title: [The improvement of periodontal teaching mode based on PDCA theory].
abstract: OBJECTIVE
  To evaluate the effect of PDCA teaching mode on clinical ability in the process of periodontal clinical internship.
  
  
  METHODS
  Forty-eight undergraduate interns coming from School of Stomatology, China Medical University were divided into 2 groups, one group received traditional teaching mode, the other group received a teaching mode based on PDCA cycle. At the end of internship, every student was assessed by theoretical examinations, case reports and clinical skill practice. χ2-test was used to determine the significant difference in clinical ability between the two groups. Statistical analysis was carried out using SPSS 13.0 software package.
  
  
  RESULTS
  In clinical skill examination, 17 students in PDCA teaching mode group got "excellent" grade , 8 students got "good" grade, none student got "passed" grade; in traditional teaching mode group, 7 students got "excellent" grade, 16 students got "good" grade, 1 student got "passed" grade. The difference between the two groups was statistically significant (P<0.05). In the theoretical examinations and case reports, 16 students in PDCA teaching mode group got "excellent" grade, 8 students got "good" grade, none student got "passed" grade; in traditional teaching mode group, 12 students got "excellent" grade, 9 students got "good" grade, and 3 students got "passed" grade. The difference between the two groups wasn't statistically significant (P>0.05).
  
  
  CONCLUSIONS
  PDCA teaching will train each student in a personalized mode, which is beneficial to finding defects existed in clinical practice and reinforcing the ability of communication and clinical practice.
