Abstract:
Objective To evaluate the effectiveness of a digital guide and assessment system in the teaching of tooth preparation.
Methods Thirty senior students of stomatology were divided into two groups randomly, with fifteen in each group. A preparation of an upper right central incisor fixed in a dental simulation model was carried out for both groups. During the preparation, students in group A were under the guidance of Dental Clinical Guidance and Assessment system, while group B were not. The amount and time of preparation, and the frequency of help-seeking of each group were recorded and the data were analyzed with rank sum test, student′s t-test and chi-square test, respectively.
Results A significantly better tooth preparation (incisor edge preparation/labial preparation/lingual preparation/smoothness) was observed in group A compared with group B. Tooth preparation time of group A and B was (34.87 ± 3.04) and (43.67 ± 2.99) min respectively, indicating a higher efficiency of the former (t=-7.985, P<0.001) . The frequency of help-seeking of group A and B was 26.67 and 93.33% respectively, demonstrating less questions were encountered in group A than group B (χ2= 13.889, P= 0.002) .
Conclusion Dental Clinical Guidance and Assessment system can help teachers improve the teaching quality of tooth preparation and accelerate students′ mastery of this clinical technique.
