Abstract：AIM: To observe the root canal variations of maxillary second molars from a clinical point of view. METHODS:150 maxillary second molars in 147 patients underwent root canal treatment were observed and the root canal morphology was observed and analyzed. RESULTS:Of the 150 maxillary second molars, 2 teeth had only 1 root canal;18 had 2 root canals;115 had 3 root canals;and 15 had 4 root canals. Second mesiobuccal(MB2) canal and second palatal canal were found in some of these cases. When the MB2 canal was present, one of the MB roots had a type V canal configuration. A type V canal configuration was also found in 1 of the teeth that had only 1 buccal root. CONCLUSION:The variation of maxillary second molars is comparatively large.
