Figure 2

Burmese maxillary first molars with Vertucci’s type IV canal in the mesiobuccal root. (a) Mesiobuccal root shows Vertucci’s type IV canal, while distobuccal and palatal roots show Vertucci’s type I canal. A sheet complete isthmus with a lateral canal was seen at the middle and apical third of the mesiobuccal root. (b) Mesiobuccal root shows Vertucci’s type IV canal with sheet complete isthmuses at the apical and coronal third. A lateral canal was originating from the isthmus in the apical third of the mesiobuccal root. Distobuccal and palatal roots show Vertucci’s type I canal. (c) Mesiobuccal root shows Vertucci’s type IV canal with a mixed complete isthmus at the middle third, and distobuccal root discloses Vertucci’s type II canal with a tube complete isthmus at the middle third. Palatal root shows Vertucci’s type I canal.
