Periodontal diseases among Quebec adults aged 35 to 44 years.

BACKGROUND: Very little information is available on periodontal diseases in Canadian adults. The purpose of this study was to estimate the prevalence of periodontal problems in Quebec adults aged 35 to 44. METHODS: A total of 2,110 randomly selected Quebec adults were examined between September 1994 and July 1995. The participation rate was 77% for the questionnaire and 44.5% for the oral examination. Measurements for gingival bleeding, calculus, epithelial attachment and periodontal pocket depths were taken for each tooth. RESULTS: More than 80% of examined persons presented with gingival bleeding on at least one tooth, and 75% presented with calculus on at least one tooth. The CPITN indicated that only 5.2% of individuals had no treatment needs, and that one out of 5 necessitated complex treatment. People with low family income, men and persons living in metropolitan areas are at higher risk of having at least one tooth with a pocket >6 mm. Dental health behaviours (regular dental visits, brushing and flossing frequency) were not significantly associated with the presence of periodontal pockets. Finally, individuals were relatively unaware of their periodontal problems. CONCLUSION: Increasing the population s awareness of periodontal diseases will be a major task for public health workers. The dental profession and the dental industry need to develop awareness campaigns to improve prevention, management and control of periodontal problems. It is especially important to target people at risk, in particular men and low-income groups. As well, dental schools and continuing education courses should focus on this problem with the aim of modifying dental practices.

{A pro-active approach to community intervention in the rural setting}.

This paper reports an evaluation study of a pilot project held in a "CLSC" (Local Community Health Centre) located in a rural community. The intervention design is based on multidisciplinary teams created to meet specific local community needs. Mental health intervention is part of a community-based approach open to all kinds of requests for support. Practitioners in the field give support not only to the individual with a mental health problem, but also to existing self-help networks in the community. The intervention is also designed to change the relationship between a professional, seen as the one who provides services, and a client, defined as a consumer. The term "client" gains a wider meaning, and collaborative work with informal self-help networks induces a closer relationship between the community and the practitioner. The practitioner is more open to local community values and adjusts his or her practice to match variable contexts. The evaluation study has expanded knowledge of this type of intervention design, on its impact upon service demand, intervention modalities, and service management and organization. This project was coupled with a similar project in an urban environment and was financed by the Health and Social Services Ministry in Québec.

R51163 as a sedative for handling and transporting plains bison and wapiti.

Forty captive wapiti (Cervus elaphus) and thirty-two bison (Bison bison bison) were tested in April and October 1988, respectively, for their response to the sedative R51163. Treatment animals were injected with either 0.1, 0.2, or 0.3 mg of R51163/kg and then observed for 72 hr. Behavior was significantly altered by the drug. Hyperactive, aggressive, and milling behavior was characteristic of treated wapiti and they were extremely dangerous and reared when hind quarters were touched. Although treated plains bison displayed some milling behavior, they were generally more calm than wapiti. There was a marked difference between sexes in plains bison for all behavioral categories. Male bison were more ataxic, often observed in sternal or lateral recumbency, less conscious, and were slower to respond than females or controls. Respiratory rate increased in treated wapiti and plains bison, and heart rates of treated wapiti increased. Because of the powerful sedative effect on large, male bison, R51163 may be useful for handling unmanageable or dangerous animals and warrants further studies.

[Oral health of 15-year-old students living in non-fluoridated public school sectors on l'Ile de Montreal in 1987].

Using data from a cross-sectional survey on 570 fifteen year old students living in non-fluoridated public school sectors on the Island of Montreal in 1987, the effect of terminating the restorative aspect of public dental health care insurance for twelve to fifteen year old students is examined. This study also highlights the level and quality of dental caries treatment on the twelve to fifteen year old group. The main point to be made is that there was an improvement in the DMFT index values of fourteen and fifteen year old students in metropolitan areas. In reality, fourteen year old children had a DMFT index of 6.45 in 1983-1984, while the fifteen year old children in the 06A region (non-fluoridated area) had a DMFT of 6.07 in 1987. Since the metropolitan fluoridated area had been eliminated from the results in 1987, it is quite obvious that the 6.07 result obtained overestimates the actual prevalence of dental caries in the metropolitan area in 1987. On the other hand, the progress which had been recorded between 1977 and 1984 by francophones in relation to anglophones was partially lost in 1987. Furthermore, this study has demonstrated that the prevalence and level of dental caries treatment are highly associated with the language spoken at home and also with the family's socio-economic status.

Dental caries in Quebec adults aged 35 to 44 years.

BACKGROUND: The purpose of this study was to assess the prevalence of dental caries in Quebec adults aged 35 to 44. METHODS: A stratified sample was used. The participation rate was 77% for the questionnaire and 44.5% for the oral examination. A total of 2,110 people were examined. The World Health Organization's caries criteria were used. Examiner agreement with gold standard dentist was excellent at the end of the nine-day training session (Kappa index > 0.8). RESULTS: The level of caries experience is very high in Quebec adults aged 35 to 44. Almost half of dental surfaces (65 of 148) have been affected. These surfaces are mostly missing (39.3) or filled (23.9). However, there were 1.8 decayed surfaces in need of treatment per adult, and more than half the people (55.5%) had no untreated decayed surfaces. Almost three-quarters of decayed surfaces were present in only 14% of the people; lower family income and lower education are risk factors. CONCLUSION: Comparison between Quebec and industrialized countries (United States, England and the Netherlands) shows that in adults 35 to 44, the mean number of decayed teeth is low (between 1.0 and 2.2) and the mean number of filled teeth is relatively similar (between 9.6 and 11.1); however, Quebec has a higher percentage than the United States of edentulous people. As well, in dentate adults, there are 1.6 times more missing teeth among Quebecers than among Americans.
