目的：通过应用根管显微镜对提高开髓术和髓腔预备技术的教学效果探讨，探索其在根管治疗术实验教学中的应用前景。方法将西安交大口腔医学五、七年制学生30名随机分为无显微镜组、显微镜示教组和显微镜操作组，记录开髓和髓腔预备的时间，采用自制《开髓及髓腔预备操作技能评分表》和《学生态度测评表》，对学生操作技能情况和学习态度进行定量评价。结果3组间操作时间均无统计学差异，P＞0．05。无显微镜组与显微镜示教组之间和无显微镜组与显微镜操作组之间操作技能评分具有统计学差异，P＜0．05，显微镜示教组和显微镜操作组评分均高于无显微镜组。无显微镜组与显微镜操作组之间和显微镜示教组与显微镜操作组之间，学生态度测评分数具有统计学差异，P＜0．05，显微镜操作组评分高于无显微镜组和显微镜示教组。结论在开髓术和髓腔预备操作实验教学中，应用根管显微镜能够有效的提高学生的操作技术，提高其对该技术的学习兴趣。作者推荐有条件的医学院校可以将根管显微镜应用到实验教学中，以改善开髓术和髓腔预备实验教学的效果。

Objective The research of the application of root canal microscope aims at examining the ad‐vantages of improving the opening pulp and pulp cavity preparation technology in teaching ,and explo‐ring the root canal microscope application prospect in experimental teaching of dental pulp disease . Method The research object is thirty students and were randomly divided into three groups ,no‐micro‐scope group ,microscope teaching group and microscope operation group ,recording pith and pith cavi‐ty preparation operation time with self‐made‘open pith and pith cavity preparation skills score table’ and‘attitude of students evaluation form’ ,to quantitatively evaluate student mastery of the skills and learning attitude .Result There were no significant differences between the three groups in operation time (P>0 .05) .No microscopic group and microscopy teaching groups and no microscopic group and microscope operating group’s operation skill score have significant difference(P<0 .05) ,microscope teaching group and microscope operating group scores are higher than the group without microscope . Between group and microscope operation microscope group and teaching group and the microscope op‐eration between groups ,attitude of students test scores have the difference of statistics P<0 .05 ,mi‐croscope operation group scoring higher than those without microscope group and microscope teaching group .Conclusion The application of root canal microscope can effectively be improved in the teaching quality of this technology in the open pulp and pulp cavity preparation teaching ,helping to improve the students’ interest in learning the technique .Recommendations can develop application root canal microscope in teaching in conditional units .
