Although collective and individual prophylactic measures have been shown to drastically reduce or totally prevent dental caries and periodontal disease, a recent survey of over a thousand twenty-year olds from all areas in Switzerland revealed an average DMFT value of 14.5, including 8.6 teeth already filled. Alarmingly, more than two thirds of all the proximal fillings examined radiographically were inadequate and therefore sources of marginal irritation. Dentistry in the future must accordingly concentrate on increased primary prevention and, where restorations are necessary, on placing restorations that will not lead to secondary caries and destructive marginal periodontitis. These goals can be most economically achieved through a team approach where the dentist delegates to his (or her) dental hygienist and specially trained chairside assistant the tasks of radiological and clinical diagnosis of caries and of marginal irritants in order to interfere with the progress of periodontal disease. The dentist, in addition, freed from administrative tasks by electronic data processing, will direct the team, and his practice will, in the future, fall into one of two large areas: preventive dentistry and/or pedodontics of curative gnathology.

The genesis of dental caries and marginal periodontopathies has a conclusive connection with dento-gingival plaque. Plaque is a constantly regenerating accumulation of salivary constituents and especially of various oral micoorganisms. Microbial decomposition of sugars from the food produces acids from fermentation which lead to local demineralization of the teeth and carious destruction. Antigenic plaque substances cause immunological reactions. With persistent bad oral hygiene, a gingivitis may develop into a progressive periodontitis with deepened gingival pockets.

The dentition of a medieval population from the former Spandau Burgwall in Berlin was investigated with regard to caries and other abnormities of the teeth, the palate and the jaws. The caries frequency amounts to 7.9%, while 63.6% of the individuals had a caries dentition. The diminuation of the caries frequency from the juveniles to the 40--60 years old individuals depends on the high rate of loss of tooth during life. Probably, all teeth which have been lost during life can be evaluated as decayed teeth. X-ray pictures have shown that three sets of teeth have hypercementotic alterations at the roots, eight permanent dentitions have cysts and apical parodontitis. Supernumerary cuspids at the toothcrowns are to be seen as a tuberculum paramolare and a tuberculum intermedium. A second upper molar has a reduced crown with only two cuspids and shows the tendency of reduction to a bicuspid. Toothrotation and other deviations of teeth from their position in the row are frequent in this material. Four deciduous dentitions of children were investigated, too. Three carious teeth were found among 45 available teeth, two deciduous molars and one first upper molar show a Carabelli's tubercle, the other first molar has a fovea carabelli.

Of the 25,672 patients who visited this clinic between January 1964 and March 1973, 126 were diabetic. These were examined statistically and the following results were obtained. 1. Together with diabetes the following disorders pertaining to the realm of oral surgery were observed: Alveolar pyorrhea (49 cases), infection of oral tissues other than periodontal tissues (24 cases), simple periodontitis (15 cases), tumors (13 cases), dental caries (9 cases), neuralgia (6 cases) and several disorders. 2. Of these 126 cases, 85 needed tooth extraction, which was actually performed in 67 cases with the following results: (a) Of the 67 cases, 13 developed complications such as dry socket, postoperative infection, sequestrum around the extraction socket, etc. This was a significantly higher incidence than in an equal number of controls. (b) In the cases with complications convalescence was prolonged to an average of 54.2 days. (c) In the cases with complications, the preoperative fasting blood sugar level averaged 194.5 mg/dl, which was much higher than in the cases which did not develop complications (average 142.4 mg/dl).

Clinical and epidemiological studies have shown that: 1. Bacterial plaque which accumulates around the teeth is responsible for chronic periodontal inflammation. From adolescence on, this inflammation is almost universal. 2. Gingivitis prepares the periodontitis, which is characterized by a migration of the epithelial attachment, pocket formation and progressive bone loss. 3. Calculus is formed by plaque calcification. Its rough surface allows bacterial retention and proliferation in contact with the epithelial covering. 4. The mechanisms of host resistance to parasitic plaque are mostly unknown. This resistance is variable and seems to decrease with age. 5. Periodontal disease in children and adolescents is a real problem in preventive medicine, because of its immediate or remote consequences on tooth loss. Thanks to fluoride, the prevention of dental caries is quite effective; the prevention of periodontal disease is on the contrary much more difficult. Mechanical removal of plaque is tedious and must be done again and again; however, it is not logical to separate prevention of caries from that of periodontal disease. Information of the public at large on oral health is of utmost importance, as well as a good cooperation of the teachers in preventive programs for schoolchildren. Every health department or service should try to apply the following measures: -Permanent employments for "school dental nurses" should be created, on a part-time or full-time basis. They should take care of the organisation and supervision of oral health programs. -In each school dental service, a dentist should be responsible for teaching the theoretical and practical aspects of periodontal prevention. -Caries reduction obtained by fluorides is no excuse to reduce the "treatment staff". This staff should be devoted to prevention at large and to refreshing courses. In a young population with regular supervision, prevention of periodontal disease can meet with considerable success. Initial periodontal disease is reversible: it is possible to avoid the degradation of gingivitis in progressive periodontitis, and this helps maintaining dental and periodontal health throughout life.

Caries and parodontitis have been one of the most spread diseases of mankind. In an archaeological study, 53 graves of Bernese patricians were exhumed. 22 skulls of adults with 392 teeth were examined. They lived between the 16th and the 18th century in the community of Worb BE. In some cases identification could be accomplished by comparison of oil paintings with skulls, using a computerized technique. The aim of this study was to evaluate the prevalence of caries, the loss of periodontal bone, the amount of calculus and of abrasion. To compare the dental situation with another population segment sex- and age-matched dates were used. This second population segment lived between the 12th and 18th century and belonged to a lower social class than the patricians from Worb. The comparison of these two groups showed significant differences only in the abrasion pattern. We conclude that the social class did not significantly influence most of the parameters studied here. The different abrasion pattern could be due to different dietary habits.

The aging of the American population will have enormous social ramifications, among which will be a greater focus on the elderly patient. Traditionally, the dental status of this group has been extracted teeth and full dentures, but that is now steadily changing. There were 41.1% of Americans aged 65 or older who were edentulous in 1985 to 1986, but a good proportion of them have been edentulous for many years. The prevalence of total tooth loss will continue to decline with time. The growth of a dentate elderly population, however, leaves more of that group at risk of caries. Caries, once seen as a disease of childhood, is now clearly a lifelong disease. Elderly persons are particularly at risk of root caries, which follows as a consequence of periodontitis. Total tooth loss and severe caries are both associated with lower socioeconomic status. Although cross-sectional survey data invariably show, on average, a greater extent of periodontitis among older than among younger persons, periodontitis is not considered a disease of aging. The age difference in surveys is not because of greater susceptibility among the elderly but represents disease accumulated over time. Limited longitudinal data suggest that rapid loss of periodontal attachment, serious enough to threaten the dentition, is found in 7% to 15% of any population. But this group exhibits the disease when young. Those who have retained a more-or-less intact dentition into old age rarely exhibit a sudden onset of periodontitis. If such a change is seen it could be indicative of broader changes in the immune system.

The purpose of this study was to evaluate the association of periodontal health and human immunodeficiency virus infection among individuals in the early stages of disease who were participating in randomized placebo-controlled clinical trials of zidovudine. Previous reports have described a rapidly progressive periodontitis and atypical gigivitis associated with late stages of infection by the human immunodeficiency virus. A health history was completed by each subject. Baseline oral examinations were completed on 97 asymptomatic patients and nine with AIDS-related complex (ARC) during their regular clinic visit. Follow-up examinations were conducted at 3-month intervals throughout the 48 weeks of the oral study. Evaluations of plaque, calculus, gingival abnormalities, caries, and periodontal disease were conducted. Periodontal measurements included plaque index (PI), gingival index (GI), bleeding index (BI), probing depth (PD), and observation for cratering, necrosis, and tooth mobility on six teeth in each patient. More than half of the subjects had visited their dentist during the previous year and had had an oral prophylaxis; less than 25% of them had had either restorative work or extractions. The mean scores for periodontal indices averaged over the course of the study in asymptomatic and ARC respectively were: PI: 0.9 (SE 0.04) and 0.9 (SE 0.08), 0.818; GI: 1.0 (SE 0.04) and 0.9 (SE 0.07), P = 0.412; BI: 0.6 (SE 0.04) and 0.4 (SE 0.07), P = 0.278; PD: 2.9 (SE 0.05) and 2.6 (SE 0.10), P = 0.140. There was no evidence of cratering, necrosis, or tooth mobility in either group. Few had calculus or dental caries. There were no clinically significant differences detected between ARC versus asymptomatic patients. Dental histories and oral examinations showed that two groups of patients in early stages of HIV-disease were in good periodontal health.

The purpose of the present study was to investigate time trends in primary reasons for extraction of permanent teeth in Norway from 1968 to 1988. Johansen studied reasons for extraction of 8757 teeth in 4216 patients during a 3-week period in 1968. Twenty years later a random sample of 500 Norwegian dentists provided particulars about all extractions carried out during a 2-week period. 350 dentists (70%) replied in 1988 but 96 of them had not extracted any teeth during the observation period. Reasons for extraction of 985 teeth from 692 patients were available for analysis. Caries and its sequelae accounted for 35%, periodontitis for 19%, and orthodontic reasons for 20% of extractions in 1988. A comparison of the distribution of extraction according to reasons for patients over 20 yr of age revealed a highly significant difference between 1968 and 1988 (P less than 0.001) mainly due to a decrease in the role of caries and an increase in extractions for other reasons. Caries and its sequelae accounted for a higher proportion of extractions than periodontitis at all ages over 20 yr in 1968, only up to 45 yr of age in 1988. Thus it is concluded that the observed time trend in primary reasons for extraction corroborates expectations based on declining caries prevalence, increasing retention of teeth and a rise in dental attendance in Norway during the last 20 yr.

The status of the oral cavity (dental caries and periodontal diseases detection) was examined in confectioners. Salivary excretion type was found changed, this shift being explained by more intensive caries and periodontitis. Prophylactic measures helped reduce caries morbidity in this population.
