In a central institution for persons with mental retardation, the dental status in 30 adult patients with Down syndrome was compared with that in a carefully selected group of gender- and age-matched mentally retarded patients. This investigation showed an increased frequency of periodontitis in the population with Down syndrome. The caries rate, however, did not differ demonstrably between the groups. Edentulism was more frequent in patients with Down syndrome than in controls, and this fact may substantiate the observation of increased frequency of periodontitis. Caries seems to be less prevalent in institutionalized patients with mental retardation than in the population at large.

The reasons for extraction of teeth were determined in a Canadian population sample of 909 patients, ranging in age from 14 to 91 years. Caries was the primary cause of extraction (63%), followed by periodontitis (34%). For the adult age groups, the percentages were approximately the same. While periodontitis was the cause of one-third of the extractions, these occurred in only one-fifth of the population. Although there is a commonly expressed belief that periodontitis is the major cause of tooth loss in adults, a review of both historical and contemporary literature does not support this position. According to the current concept of the natural history of periodontal disease, only about one-fifth of the population, or less, is likely to have periodontitis severe enough to cause tooth loss. This view is consistent with data from this and most other studies on the reasons for tooth extraction.

The author presents different approaches to dental activities in developing countries. The general prevalence of dental caries and periodontitis in developing countries is low. The limited resources for health programmes, and for oral health in particular, underscore the need to make priorities in order to improve the health of the inhabitants. To promote oral health, it is necessary to focus on improving knowledge about the major oral diseases and the possibility of developing community-based programmes of intervention and prevention. The integration of oral health into general health programmes is a major goal in the prevention and combat of oral diseases. Knowledge and research in fields of oral medicine, preventive oral programmes as well as in fluoride toxicology as part of water programmes is important.

Scientific concepts do not emerge and develop in a vacuum but in the context in which they are used. Many concepts in epidemiology have their roots in destinal general infectious diseases that occur only once in one's life. The use of many epidemiological concepts varies greatly, even within medicine. Diseases such as dental caries, gingivitis and periodontitis cannot easily be described using concepts such as prevalence, incidence or risk, without creating confusion. The concepts sensitivity, specificity and positive and negative predictive value can also easily lead to misunderstandings. Clarifications regarding the use of these concepts in dentistry are suggested.

Dental caries and chronic periodontitis may be synergistically associated, negatively associated, or completely independent. The present report examines this relationship by comparing the susceptibility to chronic periodontitis and caries within the same individual. From an 800-patient sample, a periodontitis risk score was derived by radiographic assessment of bone loss in quarters of optimum bone height and obtaining for each subject a mean score based on all measurable surfaces. Similarly the caries risk was determined radiographically from the total decayed and filled teeth (DFT), as a percentage of the total teeth measured. The Mantel-Haenszel technique was used for analysis of the relationship between periodontitis and caries and data was stratified on four categories of age, sex, and numbers of teeth present. This analysis revealed no systematic patterns, indicating that the risks of caries and periodontal diseases are unrelated (chi 2 = 0.00; 1 df; P greater than 0.50). In addition, a regression analysis, which was controlled for sex and age, indicated a marked lack of association between caries and periodontitis (P = 0.94). Thus, although these common diseases share putative etiologic factors such as oral hygiene practices and dental attendance pattern, the major risk factors are probably quite different.

A 60 item questionnaire was completed by a self-selected sample of nurses working with elderly patients. The questionnaire was divided into three sections; to collect personal data, to assess the nurses' attitude to mouthcare and their level of training in this subject, and to assess the level of dental knowledge. This paper identifies the disadvantages of using a self selected as opposed to a random sample. Analysis of the completed questionnaires revealed a fairly high level of basic training in dental and mouthcare matters. There was however, a paucity of specific dental knowledge e.g. there was some confusion over the aetiology and prevention of dental caries and also as to the difference between gingivitis and periodontitis. In addition, few nurses seemed to be aware of the effects systemic disease and drugs may have on the oral tissues. In spite of this most respondents achieved more than 50 per cent correct answers. A number of recommendations to improve nurses' dental knowledge is given at the end of the article.

This paper reports the results of an investigation on the types and frequencies of X-ray examinations given to patients with various types of their dental diseases from their first visit to the hospital to the end of treatment. The subjects were 337 patients (not including orthodontic patients and in-patients) randomly sampled out of all those who visited the Fukuoka Dental College Hospital in 1986. Out of these 337, the number of those who were given X-ray examinations was 284. 1. The Cases of dental diseases for which X-ray examinations were given were classified into the following seven: diseases caused by dental caries, trauma, inflammation, diseases of temporomandibular joint, diseases of salivary gland and other diseases, and other examinations. Out of these X-ray examinations, those given to the patients of diseases caused by dental caries and marginal periodontitis amounted to the 60% of the total X-ray examinations. 2. On the average, 3.3 radiographs were taken per patient. 3. In the examination of luxation, a case of trauma, 7.8 radiographs were taken per patient, the largest number of all diseases on this report. In the examination of marginal periodontitis, a case of inflammation, 5.4 dental radiographs and 0.5 panoramic radiograph were taken per patient. It is necessary to make the most of panoramic examination effective for this disease to decrease radiation exposure. 4. The diseases that have more difficulty of diagnosis and more necessity of observing the prognosis had a greater tendency to depend on X-ray examinations. 5. The percentage of the patients who did not receive X-ray examination was 15.7%. Out of these patients, the patients in pedodontics accounted for 34.5%.

The main employment of stomatology with curative matters and material problems caused a neglect of genetic aspects in the aetiology of dental caries and marginal periodontitis. A critical review of literature is the base of proposals for consideration of genetic aspects in the fields of stomatologic epidemiology, dental health care programs and dental health care education.

Cases of treatment because of acutely occurring states of pain were analysed in a big-city dental outpatients department. The one-year examination covered about 4,000 cases of the total number of 40,000 consultations. As for the diagnoses considered in the examination, it concerned primarily dental caries, acute apical periodontitis and pulpitis. It was to find out if here is a relation between "toothache" and airhygienic influences. This was done with reference to an examination using the same method which was performed as early as in 1982/83. Apparently, there is no immediate correlation.

Microflora from root canals and periodontal pockets of periodontally affected teeth were compared in order to elucidate the as yet unknown relationship between pulpal and periodontal disease. Caries-free teeth affected with advanced periodontitis and diagnosed as clinically dead by electric pulp testing were selected. The root canals and periodontal pockets were sampled, and the bacterial flora examined by both culture and interference microscopy. The results indicated that the aerobe/anaerobe ratio in the periodontal pocket was 0.23, while it was 0.0022 in the root canal, the large predominance of obligate anaerobes reflecting the anaerobic environment found in the root canal. Morphological classification obtained from interference microscopy showed similar proportions of morphotypes in the two sites. Results of anaerobic culture demonstrated a significantly higher rate of detection of facultative Streptococcus bacteria in the periodontal pocket than in the root canal. The predominant bacterial species common to both regions were Streptococcus, Peptostreptococcus, Eubacterium, Bacteroides, and Fusobacterium for obligate anaerobes. As for facultative anaerobes, Actinomyces and Streptococcus were detected predominantly in the periodontal pocket. The occurrence of micro-organisms common to both sites in this study suggests that the periodontal pocket may be a possible source of root canal infections.
