In order to improve the teaching quality of stomatology standardized residency training, the method of PDCA cycle quality management was tried, and 8 stomatology teachers were evaluated by 4 rounds of improvements. The evaluation included theoretical knowledge teaching satisfaction, operational skills teaching satisfaction, teaching level, teacher quality assessment, teaching quality supervision group evaluation and other indicators. The comprehensive teaching ability of all the teachers recruited in this study was significantly improved after 12 months of PDCA cycle training. The results suggest that the application of PDCA cycle helps stomatology teachers to provide high quality training to residents and provide the reference for the management of clinical teaching.
