Micro-computed tomography analysis of the relationship between root canal number and root concavity in maxillary first and second molars in a Japanese population

ConclusionsA significant relationship between the number of root canals and the depth of root concavity in the MB root of the maxillary first molars was observed. Close clinical monitoring is needed during the removal of calculus and cleaning of the root surfaces of maxillary first molars: specifically, excessive removal of cementum and dentin should be avoided, particularly when the molar has already undergone root canal treatment.
