[Alveolysis in adolescents: prevalence and correlation with the DMF index, the OHI-S index and the PM index according to sex, age and occupation (Geneva 1970-1972)].

A randomized sample of 1392 girls and boys, 16 to 20 years old and living in the canton of Geneva have been studied through their own history, clinically and radiologically in 1970-72 during an epidemiological and socio-economical study. The rate of alveolar bone resorption (radiographic method of Marshall-Day and Shourie, with Schei grid), the degree of gingival inflammation (PM index), the oral health (OHI-S index) and the carious frequency (DMFS index) have been determined. For the same sample, an indication of the duration of caries prevention through fluoride tablets, the frequency of daily toothbrushing and the dento-facial anomalies (Angle classes) were known. Through statistical analysis, it was shown that the mean rate of alveolar resorption was 0.85 (standard deviation 1,99) for the whole sample, that 24,16% of the subjects had a zero rate, 90% of the children having a rate of no more than 3,74 and that the maximum observed rate was 20. On the other hand, this bone resorption rate was statistically significantly correlated with the PM index and the OHI-S index. However no significant correlation has been shown between alveolar resorption and the other oral characteristics such as carious attack, toothbrushing, duration of caries prevention, dento-facial anomalies.

[Comparative study of 3 irreversible hydrocolloids].

This study was realized: to determine the best manipulation of 3 alginates; to compare their dimensional stability; to compare their reproduction of detail; to evaluate, through these 3 criteria, the best of the 3 alginates. It seems necessary to point out that: The 3 examined alginates show a poor dimensional stability on account of the deformations produced during the setting time and the removal of the impression. The immediate pouring of the model gives the best results, because storing the impression is accompanied by dimensional changes. The other methods of conservation seem considerably less accurate. The reproduction of detail is excellent with the 3 alginates. The accuracy is of 25 micrometer, but it is not possible to take advantage of this quality, because the compatibility and the accuracy of model stone are insufficiently adapted to the properties of the alginates. CA-37 is, among the 3 studied alginates, the one which gave the worst results with regard to the ease of manipulation and compatibility with Vel Mix Stone.

[Knowledge, attitudes and practices of physicians west of Montreal Island regarding fluoride and the prevention of dental fluorosis].

In 1991, a questionnaire aimed at evaluating the knowledge, attitudes and practices with regard to fluoride and dental fluorosis was mailed to all the general practitioners and pediatricians of the Montreal West Island territory. The response rate after two mailings was 47.9%. The pediatricians know better than the general practitioners the fluoridation status of the cities of the territory; similarly for physicians with more than 15 years experience since graduation versus the younger physicians. In practice, 92.3% of the physicians prescribe fluoride supplements or vitamins for at least some of their patients aged less than six years old. As much as 76.3% of the physicians believe that the pediatricians and the general practitioners are responsible for prescribing fluoride to children less than six years old who visit them; only 59.4% believe themselves responsible for the dental health of these children. There are educational needs concerning fluoride, fluoride prescribing and prevention of dental fluorosis. Public health dentists should assist the medical profession in this educational process.
