Effect Evaluation on a Banana-Jaw Model in Periodontal Flap Surgery Experimental Teaching
Objective To assess the efficacy of Banana-Jaw model in experimental teaching of periodontal flap surgery.Methods A total of 66 fourth year undergraduate students from Northwest University for Nationalities from April to May 2022 were recruited.They were divided into 3 groups using a random number table method:using only the banana model(B),using only the traditional mandibular model(T),and using the banana mandibular joint model(B-T),with 22 students in each group.Group B used the banana model as the training model for periodontal flap surgery;group T used a traditional mandibular model as the training model for periodontal flap surgery.The B-T group first trained with a banana model,and then trained with a mandibular model.The training time was 2 hours.All 3 groups underwent pre-clinical simulation training for periodontal flap surgery.Each group received theoretical knowledge teaching,the first theoretical test,periodontal flap operation practice,the second theoretical test,operation assessment,and satisfaction survey in order.The theoretical test scores,operational assessment scores,and satisfaction before and after experimental teaching in three groups were compared.Results There was no statistically significant difference in the first theoretical test scores among the 3 experimental groups(P＞0.05).The second theoretical test score of the B-T group[(77.27±15.73)points]was significantly higher than the first theoretical test score[(58.52±17.84)points],and the difference was statistically significant(P＜0.05).The second theoretical test score of Group B[(63.64±16.77)points]was also higher than the first test score[(53.41±13.46)points],with a statistically significant difference(P＜0.05),while the theoretical test score of Group T[(50.57±20.59)points vs.(53.41±10.34)points]before and after the second training showed no statistically significant difference(P＞0.05).The ranking of operational assessment from high to low was B-T group,T group,and B group[(79.66±3.56)points,(76.20±6.31)points,(73.18±3.81)points],and the difference in comparison is statistically significant(P＜0.05).The satisfaction survey showed that the B-T group was more conducive to consolidating theoretical knowledge and improving clinical skills,with a statistically significant difference(P＜0.05).There was no statistically significant difference in terms of classroom richness,introduction necessity,increase in operational confidence,consolidation of theoretical knowledge,improvement of clinical skills,and subjective perception of operations(P＞0.05).Conclusion The use of banana-mandibular model for teaching periodontal flap surgery can improve the mastery of theoretical knowledge and operational skills,which is of great benefit to provide an optional strategy for experimental teaching of periodontal flap surgery.
