摘要
目的:评价不同医师探寻离体上颌第一恒磨牙MB2根管口的可靠性。方法:100个离体上颌第一恒磨牙开髓后,两名医师2次独立探寻MB2根管口,2次间隔2周,用Kappa分析法评价其一致性。结果:MB2的平均发现率52.3%,2名医师2次比较的Kappa值分别为0.701和0.678,属高度一致性;同一医师自身前后比较的Kappa值分别为0.861和0.844,属极好一致性。结论:MB2在上颌第一恒磨牙中比较常见,不同医师不同时间对离体磨牙MB2根管口的判断较为稳定。
AIM ： To study the reliability of second mesiobuccal canals in extracted maxillary first molars as located by different observers at different times. METHODS： 100 extracted human maxillary first molars were determined by two observers to locate the second mesiobuccal canals independently at 2 times with 2 weeks interval . Then the results were analysed with Kappa statistics. RESULTS： MB2 were located in 52.3% of first molars. The Kappa value for inter - observer agreement was 0.701 and 0.678, Which means substantial agreement. The Kappa value for intra - observer agreement was 0. 861 and 0. 844, which means almost perfect agreement. CONCLUSION： The incidence of MB2 is familiar comparatively in first molars . The reliability of location of MB2 by different observers at different times is steaty.
