Introduction
Countless papers, surveys, and statistics attest to the magnitude of the American periodontal disease problem. In a -review of the economic and social impact of the disease, Ingle(1) stresses the insidious and painless nature of the process, which only in its later stages becomes "a personal and national tragedy." He estimated in 1969 that the total cost of prevention and treatment of periodontal disease, including costs for extractions and full denture replacement was $2.33 billion.
Periodontal disease is the leading cause of tooth loss. The 1960-62 National Health Survey considered the 75 percent rate of periodontal disease among adults 18-79 to be underestimated because 20 million persons in the survey population were excluded be- cause they were completely edentulous. Chilton and Miller(2) summarized the well-known discouraging scope of the national periodontal disease problem:
The
prevalence of periodontal disease is worldwide. It occurs from
early in the first decade
of life right through to old age. It
accounts for over 50% of missing teeth in adults
and results in tremendous economic and social burdens, both upon
the individual and
upon the society. The effect of missing teeth or a totally
edentulous mouth upon the
nutritional status of an individual can only be estimated, but it is
surely well beyond that of slight inconvenience.
Prevention is the only answer. Numerous studies support
the fact that the world's population of dentists is inadequate to meet
even a fraction
of the need, much less the demand. Preventive programs are long
overdue, and even
more affluent nations like the United States have failed to place
periodontal disease
on the head of the list of chronic diseases to be eradicated.
Background
In responding to its charge from the Executive Council, the AAPHD Subcommittee on Com- munity Preventive Periodontics has attempted to bring into focus a number of disparities between what is known concerning periodontal disease and the lack of any widespread, co- ordinated effort to control it.
The 16 member Subcommittee is made up of epidemiologists, dental public health admini- strators, periodontists, dental hygienists, and public health practitioners. This group has shared a profound sense of concern that sharp imbalances exist between programs for controlling dental caries and periodontal disease. These imbalances can be better under- stood in the context of fluoridation:
For over 35 years, increasingly widespread and successful efforts at community fluori- dation have provided a classical, efficient, and cost-effective basis for controlling a major dental disease.
Fluoridation, with its well-documented predictability, has provided a sound concept upon which those concerned with public health could "hang their hats." Understandably, then, caries became the target for a concentrated, universal effort, rather than perio- dontal disease. Although equally ubiquitous, periodontal disease simply does not respond to the same classic single-agent community preventive approaches. Moreover, it is in- sidious and painless until the advanced stages, and not well understood by a public which has been educated to perceive dental disease as caries exclusively.
And last, there are increasing indications that fluoridation's dramatic effect in re- ducing caries is affecting the nature of dental practice.(3,4) Scholle,(5) in commenting on the combined protective effect of fluoridation, topical fluorides, and sealants, sug- gests an alternative to the frustration of increased concern over decreased 'busyness':
As
we become increasingly free from the rigors of restoring the
destructive effects of dental
decay, there will be unrestrained opportunity for new achievements. For
example, earlier
and better prevention, detection, and treatment of periodontal
disease is a major challenge
for us all.
So forthrightly, in fact, have caries control and fluoridation moved from the research arena into widespread implementation that caries might be regarded increasingly as an administrative [political also-ed.] rather than as a scientific problem. Clearly, mili- tant efforts to expand fluoridation benefits must continue, and this Subcommittee does not advocate either an abandonment or diminution of effort in this regard. Recently, Faine(6) and our sister AAPHD Committee on Fluoridation have described strategies to combat a formidable new generation of sociopolitical obstacles to fluoridation which will certainly demand such intensified and innovative responses.
Nevertheless, the hard evidence of fluoridation success should allow appropriate, con- cerned agencies to reassess the nature of the national oral disease threat. Indeed, the American Association of Public Health Dentists itself is an organization which should be affected critically by such a timely examination. We advocate this position while recog- nizing that ours is an organization whose very birth and development has paralleled that of fluoridation itself. Within our membership and archives are enshrined the distinguished pioneers of fluoridation-dedicated and visionary dental scientists who have left a splen- did legacy to the children of the world.(8)
An unforeseen and unfortunate by-product of this dramatic success story has been a tunnel- vision approach to public health dentistry. A simple survey of 19 years of the Journal of Public Health Dentistry reveals only 35 papers devoted primarily to periodontal disease, out of some 350 published. This finding suggests that, historically, public health dentistry may have become primarily caries-oriented rather than concerned with oral health on a broader, more comprehensive scale. Timely reappraisal, however, of the AAPHD organizational objectives relative to periodontal diseases can have a major positive impact on the oral health of the nation, as well as on the continued relevance and vitality of the Association itself.
Subcommittee Approach to Periodontal Literature and Base of Knowledge
The Subcommittee has reviewed and shared a considerable number of individual papers related to all aspects of preventive periodontics. The immensity of the task of a thorough review, however, has necessitated a concentration on several international workshops and symposia dealing with the subject.9 -16 Each of these documents comprises a series of important position papers, includi ng extensive literature reviews, critical analyses, summaries, and recommendations. The Subcommittee has been impressed with the quality of these resources. They form a significant body of scientific knowledge which can be brought to bear on national strategy to control periodontal disease. Furthermore, directions are clearly available in their various recommendations for research, education, dental practice, and public health program development.
Jackson(17) studied the recent scientifically conducted longitudinal evaluations of the pre- ventive and therapeutic procedures in periodontics. His comprehensive review provides an accurate and valuable state-of-the-art summary of what is known:
1. Gingivitis can almost be eliminated by either daily oral hygiene [measures] alone or a combination of daily oral hygiene [measures] and prophylaxis.
2. Periodontal and gingival health seem to improve and the loss of periodontal attachment seems to diminish as the number of prophylaxes and oral hygiene ap- pointments increases up to four per year, but age, dental disease activity, economics, and practicality may influence the clinician to choose less-frequent recalls with little compromise in periodontal health.
3. Any type of treatment is beneficial, but the maximum benefit is obtained by combining subgingival deposit removal by the therapist with intensive, enthu- siastic oral hygiene instructions.
4. The value of periodontal treatment, including scaling, root planing, and surgical procedures in preventing or slowing down the rate of epithelial migra- tion is proven both in patients with initial periodontal disease and in patients with advanced periodontal disease.
5. The foregoing is valid only if the patient can maintain a plaque-free or relatively plaque-free dentition.
6. Patients unable to accomplish good oral hygiene [status] should not be subject to periodontal surgical procedures, because such procedures will, in all likelihood, increase the rate of destruction.
7. Regeneration of bone in intraosseous defects can occur with a high degree of predictability in the presence of low plaque levels.
Listgarten(18) and many other investigators also acknowledge that enough knowledge is available to prevent most forms of periodontal disease, and the difficulty of applyin this information to the implementation of effective preventive programs.
Heifetz and Suomi(19) and others(20) have appraised the value of plaque-control methods in public health programs and are plainly skeptical. They think that successful programs fro caries and periodontal disease control must operate "independent of the patients' perfor- mance and cooperation." Obviously, fluoridation rather than plaque control provides the direction in the case of caries. These papers suggest the pressing need to develop an effective chemother-peutic agent to prevent periodontal disease, especially since behaviora modification technology to effect compliance in personal plaque-control procedure is not well developed.
Sheiham(21) cautions that the American public interest in oral cleanliness is indicated by over one billion dollars in sales of oral hygiene devices: and should not be underestimated. Unfortunately, even most adult consumers think that they are controlling caries and their plaque control efforts generally are not good enough to prevent periodontal disease. Nevertheless, oral cleanliness, for whatever motivation, seems to be a reasonably integral part of the culture. It remains to be sufficiently exploited to produce a universal signifi- cant effect on controlling periodontal disease.(22)
The North Carolina Studies(16, 23, 24, 25)
More than any studies in recent years, the documents associated with the North Carolina Dental Studies have served to focus attention on a population's increasing periodontal disease problem while caries prevalence is being reduced dramatically and steadily. The studies are significant for several reasons:
The impressive collaborative project represents the combined efforts of the North Carolina Dental Society, the dental section of the State Health Department, the North Carolina State Board of Dental Examiners, the University of North Carolina (Schools of Dentistry and Public Health and Health Services Research Center), the Research Triangle Institute, the Kellogg Foundation, and the Dental Foundation of North Carolina.
Extensive surveys of dental health status in North Carolina were conducted in 1963 and 1977, allowing data comparison and analyses of the 14-year trends.
The North Carolina findings should provide directions for other states and agencies concerned with national oral health problems. They have further implications for dental education, community programs, and research. The major findings of the studies are:
1.
Caries prevalence in all age groups 30 years and younger was
significanly lower in 1977 than
in 1963. The investigators attribute the reduction to 20 years of
community fluoridation and
predict continuing steady declines as the effects of a statewide
children's preventive program
are felt.
2.
Fewer caries were left untreated in 1977 compared to 1963, and it
is estimated that present dental
manpower could restore all the new carious lesions occurring in the
population each year.
3.
Periodontal disease increased significanly since 1963, especially in
children, young adults, and
blacks.
4.
Oral hygiene scores were worse in 1977 than in 1963.
5.
General practitioners in North Carolina spend less than two percent of
their time treating periodontal
disease.
North Carolina authorities regard periodontal disease as rampant, having significantly worsened in 14 years. Thus, periodontal disease is firmly established as North Carolina's major dental public health problem.
National Priorities in Oral Health
Fluoridation and dental health were identified among 15 priority areas for health improvement in the 1979 Surgeon General's Report on Health Promotion and Disease Prevention.26 In 1980, specific objectives necessary to attain those health improvement goals within this decade
were described in a subsequent federal document, Promoting Health/Preventing Disease: Objectives for the Nation.27 Although the report was weighted toward fluoridation and considered periodontal disease the second most prevalent disease, the specific objectives for periodontal health improvement "by 1990 or earlier" included:
a. Decreasing prevalence of gingivitis in children 6 to 17 years to 18 percent, from 23 percent in 1971-74.
b. Decreasing prevalence of gingivitis and destructive periodontal disease in adults to about 20 percent, down from 24 percent recorded for adults aged 18 to 74 years in 1971-74.
c. At least 75 percent of adults should be aware of the necessity for both thorough personal oral hygiene and regular professional care in the prevention and control of periodontal disease. In 1972 only 52 percent were aware of the importance of oral hygiene, and only 28 percent were concerned about regular professional care.
The 1980 report further stated a basic assumption that organized dentistry as well as a broad range of state and local health agencies will "increase their concern for and expand their activities to support fluoridation, schoolbased prevention-oriented dental programs, and perio- dontal health promotion."
The Subcommittee thinks that any major new thrust in periodontal disease prevention should be based on official identification of periodontal disease by government agencies and dental pro- fessional organizations as the ranking national oral disease priority. Its prevalence, the relative absence of effective public health preventive measures, and the socioeconomic impact of the disease justify this priority. Such recognition will have an important bearing on federal dental research efforts, on undergraduate and continuing dental education, on practice, on strategies for community-based preventive approaches, and, of course, on the health of citizens.
The General Dentist and Periodontal Practice
Because it is universally acknowledged that periodontal diseases do not yet respond to mass medication with specific vaccines or chemotherapeutic agents, professional personnel resources must be assigned an especially critical role in preventive efforts. These roles include person- nel for health education and for all levels of prevention, diagnosis, and treatment.
The general dental practitioners should be regarded as the pivotal elements in the broad scheme of preventive and therapeutic periodontal programming. Whether in the private sector, public health, military, or institutional setting, virtually all patients seeking dental services must flow through them. In terms of efficient and effective patient management, they may refer patients with noncomplex, early disease to their hygienists for primary care. The large propor- tion of patients with intermediate stages of disease are appropriately their own responsibility for therapy. They may exercise another option for patients with advanced disease: referral to or consultation with a specialist-level periodontist.
It is at this critical point, however, where the literature reveals that the dental generalist has become, by default, part of the problem rather than part of the solution to periodontal disease. Bellini(28) observed that periodontal therapy represents less than 3 percent of the total dental service rendered to the U.S. population. A 1980 survey by the U.S. Department of Health and Human Services revealed that regardless of 20 variables analyzed, the amount of time the general dentist devoted to periodontal treatment remained constant at 5 percent, with restorative procedures (44 percent) and prosthodontics (22 percent) accounting for the majority.(29) The statistics are consistent with Douglass and Day's anaylsis(22) of dental costs in the United States. Their data reveal that patient expenditures for general practitioners' services amounted to only 7.67 percent for preventive services (94 percent prophylaxes) and only 0.78 percent for perio- dontal treatment. Crown-and-bridge services have become the nation's largest single expenditure for dental care-about 35 percent of all dental care expenses. The investigators add that "the increased cost-effectiveness (in terms of disease control and teeth saved) of these services over the basic corrective types of care is not known."
Perhaps the most disconcerting finding in the previously mentioned North Carolina studies was that the state's general practitioners report that they spend less than two percent of their time treating periodontal disease. In commenting on this observation Bawden(23) wrote:
It seems to me that our graduates have adequate backgrounds and clinical experiences in periodontics, and that failure to become involved very much in the treatment of periodontal disease is a matter of attitude on their part and the part of their patients. . . . It is time for the students to be oriented to the fact that periodontal disease is the most serious dental health problem in the state and that much more of their efforts should be directed to the management of the problem.
In North Carolina, however, "Project 80" is underway, as a joint response by the state dental society and the UNC Department of Periodontics to the manpower study findings.(25) Project 80 is a multiphasic community demonstration project aimed at intensifying education in periodontal disease awarness, prevention, and treatment for citizens and general dentists alike. Like the original studies, this follow-on effort may provide a model for similar projects on a national scale.
There are many possible explanations for periodontal noninvolvement by general dentists. Generally, they lack confidence in periodontal diagnosis, treatment planning, and therapeutic procedures. Many do not understand or fully appreciate modern concepts of periodontal disease control and cure. Virtually all practitioners are more comfortable, more intrigued, and more challenged by traditional reparative styles of practice, including the associated economic aspects. Unless they become periodontally oriented, however, these traditionalists-the majority- may not be able to survive from an economic standpoint as the effect of fluoridation on caries- related dental practice increases. Research exploration of dentists' attitudes toward periodontal disease, their knowledge and technical deficiencies, their periodontal practicemanagement skills, and mechanisms to retain and remotivate them should carry a high priority. The entire approach to periodontal diagnosis and treatment must be simplified for both student and practitioner so they will not be awed by the process.
The responsibilities of practice aside, the non management of periodontal disease for those in society who seek care is a national disaster. Eventually, the legal pressures and consumer mili- tancy may force an improvement sooner than internal professional monitoring can correct the situation.
Consumer advocacy for improved dental service was heightened with publication of a dentist directory, including guidelines for selection of a dentist, by a Washington-based organization, the Public Citizen's Health Research Group.30 The comprehensive directory provided recommen- dations and patient-consumer expectations for health assessments, plaque-control programs, radiation safety, and descriptions of a periodontal examination which might have appeared in a dental text:
PERIODONTAL EXAMINATION (gum examination) The dentist should make note of any area of bleeding gums, tooth mobility or unusual colorings or the presence of bad breath. He should also use a tapered thin instrument (periodontal probe) to examine the depth of the space between the gum and the tooth as an indication of the health of your gums and supporting structures. The measurement of the periodontal pocket depth (normal is 0-3 mm, or 1/8 inch) plus a standardized oral hygiene index should be included in your dental record. Ask your dentist what your pocket depth is and your plaque index (oral hygiene index). (Remember, 67.9% of those between 12-17 years had some form of gum disease.) - Bleeding gums are not healthy and (are) an indication of disease!
It is apparent that building a "constituency" in support of periodontal disease prevention can have a potent negative impetus as well as the better-known positive, professionally sponsored variety. Organized dentistry's perception of consumer power must be considered unclear at this time.
Cohen has been one of the most eloquent and persistent critics of the generalists' minimal dedication to the periodontal needs of the population. At the 1981 National Conference on Dental Education,31 he suggested that the phenomenon is a reflection of the traditional emphasis of most dental curricula, where restorative, prosthodontic, and oral surgery departments are dominant.
Focusing on the growing consumer alarm over professionally neglected periodontal disease, Cohen states:
It is tragic to learn of the large numbers of patients who have been receiving care on a regular basis, only to find out that they are suffering from advanced periodontal disease. It may surprise a reader of the litigation section of the Journal of the American Dental Association to learn that there are more than 300 malpractice suits pending in the State of California alone, initiated by patients with chronic periodontal destruction against dental hygienists and dentists who were responsible for their maintenance care.
Wade(32) found that plaque scores and plaque control of dentists (themselves) were worse than those of patients. When such depressing information is coupled with the aforementioned indi- cators of negative dentist attitudes toward periodontal disease, it becomes obvious that the dentist is something less than a dependable resource in the preventive periodontics campaign.
Dental Hygienist or Preventive Periodontal Therapist?
The Subcommittee has indicated previously that in the global scheme of preventive periodontics, the general dentist-for better or worse-is the pivotal element. Searching analysis of both literature and practice, however, will reveal that it is the dental hygienist-of all those in the dental professional hierarchy-who is the critical element in that same scheme.
Because of a complex of social, political, legal, and economic factors, however, the full potential of the hygienist resource has not been brought to bear optimally on the nation's primary oral health problem. Current evaluations of the hygienist's role are frequently over- shadowed by the issue of independent practice-a natural, predictable outgrowth of improved education, expanded responsibility, and enhanced professionalism.
O'Leary, Koerber, and Catherman(33) compared specially trained dental hygiene students with senior dental students in a variety of "periodontally expanded functions." The hygienist- trainees were significantly better than the future dentists in periodontal examination, probing accuracy, tooth mobility and plaque assessments, and root planing. Root planing, in particular, is the basis for all phases of periodontics: prevention, treatment, and maintenance. Cohen31 considers root preparation to be the most difficult technique to master in the entire dental repertoire.
With these skills, then, coupled with the dentists' well documented abdication from periodontal responsibilities, it is logical to regard the dental hygienist as the primary preventive therapist in periodontics.(34) Indeed, there may be as much merit in increasing the hygienists' training and influence in periodontics as there may be in exhortations to general dentists to increase their periodontal activity-a minicapitulation to their strong reparative heritage. Corollary to this proposition is a realization that efforts to expand the hygienist's role in restorative rather than periodontal disciplines are misdirected.
Schallhorn(35) describes in considerable detail the importance of maintenance therapy as "the most critical aspect of dental treatment." He provides a comprehensive review of both hygienist and dentist responsibilities in all phases of preventive periodontics, including a minute-by-minute procedure analysis of a typical preventive recall appointment. Few papers in the recent literature have highlighted the transcendant role of the hygienist as effectively. The number of practicing dental hygienists has increased tenfold during the past 30 years from 3,190 in 1950 to 32,200 in 1977. Unfortunately, however, there may be as many hygienists not practicing as there are those in practice. This great pool of trained therapists could possibly be reactivated by new strategies in periodontal disease control and by facilitation of reentry into practice for working parents. The number of trained hygienists will likely continue to increase throughout this decade.36 They should be given [seek-ed.] an increased role in the control of periodontal disease in both the public as well as the private sector, free from unnecessarily restrictive provisions in dental practice acts. The dental profession must acknowledge eventually that dental hygienists are even more appropriately trained to provide preventive periodontal therapy than dentists.(33) This is especially true in view of the fact that the economics of preventive periodontal therapy as provided by the hygienist are favorable not only to the patient and to the hygienist but to the dentist and the public health administrator as well.
Strategies for a National Program
The growing realization of the primacy of the American periodontal disease problem evokes a natural interest in developing a broad strategy for preventing the disease, or controlling it sufficiently to lessen its impact on society. Unfortunately, in addition to the recognized lack of a specific preventive agent, the absence of a universal, powerful constituency for periodontal disease eradication presents a formidable barrier to progress.
Many targeted, federally supported health programs have been initiated because of the lack of an adequate knowledge base to identify potential preventive interventions in the disease process. Kidney disease, diabetes, and sickle-cell anemia have benefited from such infor- mational deficiencies, but the common factor in the initiation of these programs seems to have been the political influence of a large and vocal group of people who are affected by the disease or condition, either directly or indirectly.
In the instance of periodontal disease, the constituency vacuum is complicated. The public does not seem aware that a serious oral health problem exists. Moreover, only a fraction of the half of the American population who may seek other than just episodic dental care have had their periodontal needs diagnosed and treated. In the absence of a massive simultaneous effort to motivate dentists toward periodontal involvement, intensive campaigns to encourage people "to see their dentists" seem almost thoughtless.
Neither the professional public health community, the federal government, nor the dental research and educational sectors have realistically contributed to the type of constituency necessary for society-wide periodontal disease control. To get things going, this Sub- committee has developed an interest in exploring the concept of a "National Periodontal Disease Program." Rather obviously, a model exists in the National Caries Program, which serves to coordinate and amplify a wide range of anti caries initiatives in addition to fluoridation. Without a constituency, however, such an approach is probably inopportune.
Short of the "task force" approach, however, the Subcommittee feels that progress can be made through realignment-toward the periodontal disease problem-of overall emphasis, staffing, and budgets within the federal and state dental agencies. Furthermore, through improved coordination- internally, and externally with other organizations-some progress may be anticipated through such initiatives by the AAPHD. For example, the American Association of Public Health Dentists should stimulate development of a permanent Committee on Public Health within the American Academy of Periodontology, while it strengthens its own programs in periodontics. Such organi- zational cross-fertilization is vital in building an information exchange system.
The Subcommittee is emphatic that the major thrust of preventive periodontics programs in public health be directed toward children and youth. Recognizing the early insidious onset of periodon- tal disease in the teens and early adulthood, effort should be directed toward improving the periodontal health of the young. Some dental public health programs shun supervised brushing and flossing in school programs because of their lack of evidence in reducing caries incidence significantly. Nevertheless, it is the only means of plaque removal which can be done on a daily basis. Clinical studies should be conducted to ascertain the impact of plaque control, as used in the supervised classroom setting, upon the incidence and severity of periodontal disease in school-age groups.
Cons(37), describing the dental health program for the State of New York Department of Health, comments on the statistics of the National Health Surveys relating to periodontal disease in children. While the statistics reveal that 68 percent of youth ages 12-17 have periodontal disease, only 5.8 percent have destructive periodontal disease characterized by pockets, and the remainder have only relatively mild gingivitis associated with a few teeth. This same report indicates that 39 percent of children 6-11 have periodontal disease and one out of 125 has evidence of chronic, destructive periodontal disease characterized by pockets. Forty percent of this age group had some degree of gingivitis, mild in severity and limited to only a few teeth. Unfortunately, the report comments that periodontal disease to most youths is not perceived as an imminent threat.
While concentrating on the preventive approach for the young, care must be taken not to neglect the adults who are presently experiencing the results of the lack of prevention and care in their early years. Whatever public thrust is designed to bring home the message otprevention of periodontal disease must include some direction for the current sufferer. As a profession, we should be prepared to shoulder the task of alleviating or, at least, slowing down the onslaught of periodontal destruction in the adult population.
New Strategies in Periodontal Disease Control
Many old beliefs about dental disease control must at last be put to the scientific test if much improvement is to be achieved in the periodontal health of the population. Dental health education in the form of plaque-control instruction has frequently been found inef- fective in public health clinical trials. The problem here may not be the objective but the unacceptability of the plaque-control methods that were offered as a means of reaching the objective and the age group at which they were directed. It is possible to interpret the literature to show that ideal brushing and flossing may be unreasonably difficult skills for all but a few compulsive individuals to master. Other methods of oral hygiene must be evaluated. Among these are antibacterial rinses and subgingival cleaning devices such as toothpicks and flexible points.
Recent advances in preventive periodontal theory which may provide needed new therapeutic strategies center on the work of Loe, Loesche, Keyes, and Listgarten.(38 41) These investigators and others have focused clinical attention on specific target organisms in the oral microflora and evaluated chemo-mechanical treatment regimens designed to suppress or eliminate them. The continuing search for an acceptable antibacterial agent has recently begun to focus on low concentration stannous fluoride compounds which offer previously established anticariogenic benefits along with strong antimicrobial effects.42 It is necessary to develop such an agent which could be used daily in combination with simple mechanical cleansing technics to control both crown and root caries as well as disease of the periodontium. This combination is particularly needed if we are to realize an effective preventive perio- dontics program suitable for implementation as a public health measure.
It is now evident that caries is being brought under control not by toothbrushing but by fluoride compounds in drinking water, dentifrices, gels: and rinses. By contrast, it seems that the control and prevention of .periodontal disease will not be accomplished so much by means of the toothbrush and dental floss as by antibacterial agents, microscopic bacterial monitoring, and simple-to-use subgingival and interproximal cleansing devices. These latter methods could be utilized by dentists and hygienists in either the public health or the private practice sectors. It is possible to foresee public dental clinics and private practices exclusively devoted to the diagnosis, prevention, and control of dental diseases. In the past such practices would not have been technically or economically feasible, yet today they may become a reality as competition in the dental marketplace intensifies and as innovative forms for the provision of dental care emerge.
Thus, an understanding of the historical neglect of periodon!al disease by general dentists and dental public health specialists alike can provide, at least, a logical basis for productive, timely new partnerships. For example, massive public health promotional efforts, coupled with public health-managed clinics for periodontal disease screening and detection, can be coordinated with extraordinary referral initiatives involving the private sector.
Whereas these partnerships obviously challenge and serve dental professionals, they probably provide the best hope for widespread periodontal control for the nation until the scientific research gap is closed.
Conclusions
1. Caries is responding so dramatically to preventive and treatment measures in society, especially community fluoridation, that periodontal disease should now be recognized and established as the principal oral disease threat in the nation.
2. Private general practitioners and dental public health programs at all levels have neglected periodontal disease. 3. There is an impressive body of knowledge that can be brought to bear on the diagnosis, prevention, and treatment of periodontal disease, which is widespread in society without an effective preventive system.
4. Research in periodontal disease may not be directed or targeted efficiently.
5. There is enough knowledge available to prevent most forms of periodontal disease. There is, however, a critical need for coordination of research, administrative, and health care efforts to control/prevent periodontal disease at the organizational, state, and national levels.
6. There is a need for a powerful, efficient, and sustained public health educational and promotional program to enhance awareness of periodontal disease in the public at large as well as in practitioners of dentistry.
7. The most critical research needs identified are:
a. the development of effective and acceptable chemotherapeutic agents to prevent periodontal disease,
b. determination of the role of professional and patient behavior in the maintenance of periodontal health,
c. investigation of the role of inadequate nutrition in enhancing susceptibility to periodontal disease, d. design and evaluation of the effectiveness of improved dental health care systems on the periodontal health of communities, and
e. studies on how effectively to educate and motivate the general dental practitioner to recognize and treat periodontal disease in its early stages.
Recommendations
1. The American Association of Public Health Dentists should adopt the position that periodontal disease is the greatest oral threat to health of the American people. AAPHD should recommend to the ADA and APHA that they adopt a similar official posture.
2. The American Dental Profession needs to undertake an aggressive effort to bring the problem of periodontal disease in the United States under more effective control. Prevention of the disease should have the highest priority.
3. The American Association of Public Health Dentists should examine its internal organizational structure to determine if its present resources and philosophical orientation are directed sufficiently toward the prevention of periodontal disease.
4. The American Association of Public Health Dentists should assume leadership in establishing an interorganizational committee to coordinate and act as a clearing- house for national preventive periodontics matters: research, demonstration projects, public information, and continuing education. Participation should include the American Dental Association, The American Academy of Periodontology, The American Dental Hygienists' Association, The Academy of General Dentistry, and elements of appropriate federal health agencies.
5. The American Association of Public Health Dentists should initiate planning for a major, multimedia health education program to inform the public of the threat that periodontal disease poses to the oral health of every citizen.
6. The American Association of Public Health Dentists should assign a high priority to establishment of oral health programs in elementary, junior, and senior high schools. Such programs would include oral health education and promotion as well as preventive caries and periodontal disease pliOQrams. Plaque-control programs should be explained, conducted, and targeted, as much as possible, to the prevention of periodontal disease.
7. The American Association of Public Health Dentists should establish a major workshop to explore ways to build a broad-based national constituency dedicated to prevention of periodontal disease. Participants should include representatives from consumer-advocate groups; federal health agencies; federal and state legislatures; national education and parent-teacher associations; third-party payment industry; national communications media; marketing, advertising, and public opinion survey organizations; labor unions; and the dental profession.
8. The American Association of Public Health Dentists should establish lines of communi- cation with elements of the North Carolina Dental Manpower Project, including a special liaison team. This initiative should assess the impact of the North Carolina studies on other state populations and explore the development of state and national demonstration projects dedicated to periodontal disease awareness and prevention.
9. The American Association of Public Health Dentists should assign a special task force to study the feasibility of establishing a national periodontal disease program.
