ROOT CANAL RE-TREATMENT OF MAXILLARY FIRST MOLAR WITH FOUR CANALS USING HYFLEX EDM: A CASE REPORT

Abstract

The root canal system presents a complex anatomy. It is a myriad complex of canals and their various portals of exits. The maxillary first molar is an important tooth in the arch and is of prime functional importance. In maximum cases, the maxillary first molar shows presence of three canals viz. mesiobuccal, distobuccal and palatal canal. At times, there may be presence of four or five canals. These extra canals may be present as a second mesiobuccal canal, a second distobuccal canal or an extra canal in the palatal root. These canals are often missed by the clinician. Their identification has benefitted from technological innovations like microscopes and ultrasonics that have enabled easy identification of the orifices of these canals. This case report presents a case of root canal treatment of maxillary first molar with four canals.
