Root Canal Configuration of Burmese (Myanmar) Maxillary First Molar: A Micro-Computed Tomography Study

Figure 3

Burmese maxillary first molars with supplemental root canal configurations. (a) Mesiobuccal root shows Vertucci’s type VIII canal, while distobuccal and palatal roots reveal an additional canal type (3-2) and Vertucci’s type I canal, respectively. Sheet complete isthmus is connecting two additional mesiobuccal canals at the apical region of the mesiobuccal root, and tube complete isthmus is communicating between canals in the distobuccal root at all thirds. (b) Mesiobuccal root shows an additional canal type (4-4), while the distobuccal and palatal roots reveal an additional canal type (1–3) and Vertucci’s type I canal, respectively. Sheet complete type isthmus is connecting four mesiobuccal canals at the coronal, middle, and apical regions of mesiobuccal root. (c) Mesiobuccal root shows Vertucci’s type VIII canal with lateral canals at the apical third and sheet complete isthmus at the middle third. Both distobuccal and palatal roots reveal Vertucci’s type I canal with a lateral canal at the apical third.
