Due to each tooth singularity a vast number of morphological variations is possible. Such variations increase the difficulty in shaping, cleaning and filling the three dimensional root canal system.( Vertucci et al 2009). Probably, the tooth with the widest range of anatomical differences is the maxillary first molar ( Vertucci 1984, Cantatore et al 2006). A number of studies have been published on the anatomy and morphology of the maxillary first molar, depicting a great variety of anatomical configurations on this tooth. The majority of papers concern themselves mainly with the anatomy of the mesiobuccal root of maxillary first molar, and…
