Maxillary second premolar with three canals Report of three cases

Clinically, precise determination of the internal structure of teeth, their form and number of canals could be a challenge. Correct radiographic interpretation can help in revealing additional roots or canals and further clinical observation and exploration of pulp chamber are necessary to rule out additional canal. Only a sound knowledge of teeth morphology and correct radiographic interpretation can help a clinician to predictably manage unusual cases. Maxillary second premolar often present with either having single or two canals. It is rare to see three canals in the maxillary second premolar. This article describes three cases of maxillary second premolar with three canals among the middle-east population which were diagnosed and treated successfully.
