| Abstract: | Aim To investigate the clinical incidence of the second mesiobuccal root canal of maxillary first molars.Methods Incidence of the second mesiobuccal root canal of maxillary first molars was determined by using the modified access preparation and probing the fissure or groves between the mesiobuccal and palatal canal orifices.Results Of the 24 maxillary first molars of 20 patients,14 of the molars had second mesiobuccal root canals.The incidence rate was 58.3%.Conclusion Identifying and treating the second mesiobuccal root canal in maxillary first molars is improved by modified access preparation and probing the fissure or grove between the mesiobuccal and palatal canalorifices. |
