Configuration of Canal System in the Mesiobuccal Root of Maxillary First Molars

Knowledge on internal dental morphology is extremely important to the correct execution of the treatment and modeling of root canals. The aim of the present study was to analyze, "in vitro", the configuration of the canal system in the mesial root of 180 maxillary first molars obtained fro...
