上颌第三磨牙根管形态的CBCT研究
A study of root canal morphology in maxillary third molars using cone-beam computed tomography
摘要
Abstract
Objective This study investigated root canal morphology in maxillary third molars by CBCT to provide an anatomical guideline for clinical treatment. Methods CBCT images of 397 maxillary third molars were collected. The root canal morphology was analysed, including the number of roots and the type of canals. Results In 397 maxil⁃lary third molars, three roots were the most frequently type, accounting for 43.07%and the fused root teeth were the sec⁃ond, accounting for 40.30%. For the root canal type, three canals were the most common, accounting for 47.86%, fol⁃lowed by single canal, accounting for 28.21%. According to the Vertucci root canal classification, 89.6%of the root ca⁃nals were typeⅠ, the rest were typeⅡ, typeⅢ, typeⅤ, and other types of root canals which were difficult to deal with in clinical treatment. Conclusion The root canal morphology of the maxillary third molar is various and the root canal system was complicated.关键词
