摘　　要：目的:探讨头戴式放大镜在口腔规培生上前牙全瓷冠预备训练教学中的效果。方法:选择口腔修复专科低年级住培生18名随机分为A、B两组;A组先完成裸眼下3例右上中切牙全冠牙体预备,然后完成3例头戴放大镜下的牙体预备;B组先完成3例头戴放大镜下右上中切牙全瓷冠牙体预备,然后再裸眼完成3例牙体预备。对备牙效果进行评分,对比差异,并通过调查问卷分析评价头戴式放大镜的使用体会。结果:口腔规培生头戴放大镜进行右上中切牙全瓷冠牙体预备效果评分(86.80±3.19)显著高于裸眼下预备得分(81.60±4.49)(P<0.05)。问卷调查结果显示头戴放大镜辅助下,视野清晰度更好,备牙结果也更优秀,但操作流畅度不如裸眼操作。结论:头戴式放大镜辅助教学应用可有效提高口腔规培生上颌前牙全瓷冠牙体预备质量。Objective:To evaluate the effects of using magnifier in the training of maxillary anterior all-ceramic crown preparation.Methods:Eighteen dental students were randomly divided into two groups,group A carried out the prepa-ration of three cases of the right maxillary central incisors with unaided eye first,followed by the preparation of three addition-al cases using magnifier.Conversely,group B first completed three cases of right maxillary central incisor all-ceramic crown preparation with magnifier and then three cases of tooth preparation with unaided eye.The outcomes were scored and ana-lyzed,and the experience of using magnifier was evaluated and analyzed through a questionnaire.Results:The scored with un-aided eye group(81.6±4.49)was significantly lower than the group with the aid of magnifier(86.8±3.19)(P<0.05),and better definition and outcome was described as seen in the questionnaire.But the tooth preparation process with unaided eye was more fluent.Conclusion:The use of magnifier in the training of maxillary anterior all-ceramic crown preparation is effec-tively.
