The teaching of geriatric dentistry in Canada.

Very little is known about the current status of geriatric training programs at Canadian universities because of the scarcity of information published on the subject. A study of the geriatric dentistry training programs offered by Canada's 10 dental schools has been completed. Its intent was to determine what type of educational activities in geriatric dentistry have either been offered in the past, are being offered now, will be offered in the next academic year, or are planned for the next five years. The results indicate that the 10 schools are doing very little in this regard. To keep pace with the level of geriatric dentistry training currently being offered in the United States, the dental profession must convince Canadian faculty members that the teaching of geriatric dentistry is crucial to both the undergraduate student and the graduate dentist. Continuing education in geriatric dentistry could be used to meet the oral health needs of our frail and dependent senior citizens. Geriatric dentistry must be taught at all levels of the profession so that this special clientele can receive the necessary treatment either within or outside of the dental office.

Clinical evaluation of two posterior composite resins: two-year results.

Two composite resins were evaluated for clinical acceptability as restorative materials in Class I and II cavities over a 2-year-period. In addition, dispersed phase alloy was evaluated for comparison. All restorations were assessed for anatomical form, marginal integrity and marginal leakage using modified United States Public Health Service (USPHS) criteria. At the 2-year recall, 96% of the composites and 100% of the amalgams were rated 'alpha' or 'bravo', using the parameters of assessment defined in this study. However, a significant number of shifts from the baseline, within the level of acceptability, had occurred. The two composites showed the greatest number of shifts for anatomical form and marginal leakage, while there were no differences between the composites and the amalgam for shifts in marginal integrity. Although a very high level of acceptability was determined for all of the materials, the frequency of rating change within categories for the composites was a cause of concern with regard to their long-term clinical use.
