Simulation for training in oral cancer biopsy: a surgical model and feedback from GDPs.

Abstract

OBJECTIVES: To describe a new bench model for oral precancer/cancer biopsy training and to assess its effectiveness in terms of trainees' perception. STUDY DESIGN: Cross-sectional, descriptive, performed on 424 general dental practitioners (GDP) who undertook biopsies on a pig tongue. The participants were assessed by direct observation for 2.5 hours using specific check-lists and by means of a self-applied questionnaire. RESULTS: The workshop was perceived as "very interesting" even by those with previous surgical experience (Xi - Xj = 0.07; 95%CI= -0.20-0.09). Most GDPs considered themselves able to undertake oral biopsies on real patients after the workshop. Those who had previously received theoretical continuous education courses on oral biopsy scored higher values within the group (Xi - Xj = 0.20; 95%CI= 0.04-0.37). CONCLUSIONS: There is a need for including clinical abilities workshops when instructing on oral biopsy techniques. More studies are needed to validate the procedure and to address cognitive and communication skills.
