【摘要】：探讨上颌第二乳磨牙近颊第二根管(MB2)的特征及临床治疗方法。选取患牙髓炎或根尖周炎的上颌第二乳磨牙95颗,拍摄术前及根充后X线片,采用耳鼻喉内窥镜观察测量髓室底各根管口位置关系;术中采用10号锉结合17%EDTA凝胶探查根管,手动器械进行根管预备,螺旋输送器导入Vitapex糊剂充填根管。在95颗上颌第二乳磨牙中,有14颗存在MB2,发现率为14.7%,MB2位于MB-P根管口之间假想连线的近中。
[Abstract]:To explore the characteristics and clinical treatment of maxillary second molars with mesiobuccal second root canal (MB2), 95 maxillary second molars with pulpitis or periapical periodontitis were selected and X-ray films were taken before and after root filling. The relationship between the root canal orifice and the root canal orifice of the pulp floor was observed by endoscope, and the root canal was detected with 10 file and 17TA gel during the operation, and the root canal was prepared with manual instruments. In 95 maxillary second primary molars, 14 of the 95 maxillary second primary molars were found to be MB2, with a detection rate of 14.7mb 2 located near the imaginary line between the MB-P root canal orifices.
