Quality and adequacy of training of expanded function dental auxiliaries in the U.S. Army.

This study explores the quality and adequacy of training U.S. Army expanded function dental auxiliaries (X2s). Data were collected in the spring of 1989 using self-administered questionnaires from dental commanders, clinic chiefs, X2 graduates, dentists working with X2s, and potential X2 students. Nearly all (94.2%) dental activities personnel responded. Results show overall performance of X2s was rated excellent or very good by 76% of commanders, 70% of clinic chiefs, and 42% of dentists. Of 23 job-specific tasks assessed, X2s received lowest performance ratings for placement of complex composite restorations and highest ratings for individual topical fluoride application. Of X2 graduates, 82% rated the overall quality of X2 training as very good or excellent. X2 graduates and their supervisors recommend retaining each job-specific skill in the X2 training program while lengthening the program from 16 to 28-30 weeks. Training of U.S. Army X2s may offer a model to other dental care systems with limited resources.
