METHODS:Fifty two permanent maxillary first molars,which were diagnosed as pulpitis and periapical periodontitis clini cally,were selected.The pulp chamber floors were examined and detected to locate the mesiolingual canals(MB2) by naked eyes and SOM respectively.
由于其近颊根通常有近中颊和近中舌(MB2 ) 2个根管，而其近中舌根管细小且根管口常较为隐蔽，因此，Weine认为上颌第一恒磨牙根管治疗失败的一个主要原因是治疗中遗漏了MB2根管。

It is concluded that the ZOE with FC is not biocompatible with UB2BOS and the cell death is by apoptosis. Clinically, we suggested that Vitapex is a good choice in primary tooth root canal filling.
作者认为当细胞与传统乳牙根管充填材料作用后，细胞发生死亡之途径可能经由细胞本身之自杀，临床上使用Vitapex作为乳牙根管充填剂是可以接受的。

dentine：牙质
牙主要由牙质(dentine)构成,内部的腔隙称牙腔(cavum dentis). 牙腔与牙根内的牙根管相通,根管末端有一小孔,称牙根尖孔. 活体牙腔内充填有结缔组织、神经和血管,称牙髓(pulpadentis). 牙髓有营养牙和形成牙质的作用.
