PGD training and its impact on general dentist practice patterns.

This study compares the practice patterns of general dentists with and without formal advanced training in AGED or GPR programs. The UCLA School of Dentistry surveyed a random selection of dentists from graduating years 1989, 1993, and 1997 as part of a Health Resources Services Administration (HRSA)-supported evaluation of the impact of federal funding on postgraduate general dentistry (PGD) programs. Using a sample drawn by the American Dental Association (ADA), 6,725 dentists were surveyed about their practice, advanced training, patients served, and services provided. Of the 2,029 dentists (30 percent) who responded, 49 percent were practicing dentists with no formal advanced training in general dentistry or one of the eight ADA specialties; 7 percent had Advanced Education in General Dentistry (AEGD) experience; 20 percent trained in a General Practice Residency (GPR); and 24 percent were specialists. Additionally, 7 percent of respondents had PGD training and a clinical specialty. GPR-trained dentists were significantly more likely to be on a hospital staff and to treat medically compromised patients even after ten years of practice. PGD dentists were less likely to seek specialty training. Major reasons for seeking PGD training were increasing treatment speed, learning to treat medically compromised patients, and wanting hospital experience. Primary reasons for not selecting training were starting a practice and having a great practice opportunity. Our conclusion is that PGD training has an enduring impact on practice patterns and improves access to dental care for underserved populations.
