A realidade da morfologia endodôntica nas raízes vestibulares fusionadas dos segundos molares superiores

Abstract

There is doubts about the endodontic morphology of the buccal region of the upper second molar when it showed the buccal roots fusioned. This paper was performed to determine the number of root canal when the tooth presents the buccal roots fusioned. Fifthy nine upper second molars that presented the buccal roots fusioned, extracted for different reasons without atention to age, sex or race, was used. After the cross-cuting at the anatomic neck the root canal was opened by endodontic instruments and painted with black ink, for best visualisation. Finaly the roots were sliced with burs in the cervico-apical direction. We found four groups of teeth based in the number of root canal and/or apex foramen.
