The prevalence of missing teeth has been described for US adults, but little is known about the incidence of tooth loss in any segment of the population. This study investigated the 5-yr incidence of tooth loss in a random sample of Iowans aged 65 yr and older residing in two rural counties. These people had an average of 20 teeth at baseline and approximately 40% lost at least one tooth in the subsequent 5 yr. The incidence of tooth loss was highest for mandibular molars and lowest for mandibular canines. Men were more likely than women to lose teeth. Although we were able to identify a number of statistically significant potential risk factors for tooth loss, the multivariate models that incorporated all these factors were not good predictors of which people were at highest risk for tooth loss.

These results suggest that tooth loss continues in the very old, that periodontal attachment loss is associated with tooth loss in this age group, and that loss of teeth over one's lifetime does affect certain quality-of-life measures.

A faculty of sufficient size and possessing the appropriate skills is critical to dental education. Faculty shortages have been identified, but little has been written about the skills and abilities necessary for dental faculty to be effective. This project identified consensus lists of competencies in the areas of teaching and research. A panel of dental education experts used a web-based Delphi method to refine competency lists. The final lists of competency statements were organized into foundational competencies that applied to all areas and several areas of major competencies that were defined by supporting competencies. The panel rated the importance of each competency statement for each of three dental faculty categories: 1) clinical teachers, 2) clinical scholars, and 3) research-intensive scholars. The identification of a consensus list of competency statements for effective dental faculty will facilitate the development of programs for faculty to attain and maintain these competencies. ADEA could play a coordinating role in this faculty development effort.
