RESUMO
The number of graduates of U.S. dental schools enrolled in U.S. postdoctoral programs in periodontics has been decreasing. The aims of this study were to determine the perspectives of periodontics department chairs regarding 1) features of a school's predoctoral curriculum that promote student interest in advanced periodontal education and 2) characteristics of a periodontal residency program that make it more attractive to dental students over other specialty programs. In 2015, a 14-question survey was designed and sent to chairs of periodontics departments at all 65 U.S. dental schools at the time. Questions addressed number of instructional hours; specialty clinic rotations; elective courses; number of applicants to periodontal residency; existence of a residency program; length of the residency program; and externships, fellowships, and financial stipends offered. The survey response rate was 73.8%. The results showed that departments offering more than seven clinical credit hours in periodontics to predoctoral students had the greatest number of residency applicants. Most of the applicants were from institutions that offered specialty clinic rotations, elective courses, and residency programs in periodontics. The number of applicants did not change significantly if a stipend or fellowship was offered. However, the availability of an externship was significantly associated with a greater number of applicants (p=0.042). These results suggest that offering periodontal clinical rotations, elective courses, and especially externships in periodontics during predoctoral education may encourage more graduating students to pursue postdoctoral periodontal education.
