Importance of preoperative diagnostic imaging in treatment of maxillary central incisors with Vertucci's type V root canal configuration – A report of 2 cases

Abstract

Root canal system typically has a diverse canal configuration. One of the most difficult aspects of ensuring successful endodontic treatment is accurately identifying all canals found in a tooth. Diverse root canal configurations are not uncommon, even if the majority of maxillary incisors have a single root canal. One canal bifurcating into two at the apical third is exceptionally rare, with only two case reports previously reported. For the precise diagnosis of certain anatomical peculiarities, a thorough evaluation of preoperative diagnostic radiographs is highly required. As of periapical radiography, which is the most important diagnostic imaging for determining root canal anatomy, is limited by its two-dimensional nature, technological innovations such as cone beam computed tomography can be extremely beneficial. This paper emphasizes the significance of preoperative diagnostic imaging in the treatment planning of maxillary central incisors with unusual root canal morphology.

Bifurcation of canals in temporary upper central incisors

“…Las anomalías en la morfología dental en los dientes primarios son comparativamente menores que en los dientes permanentes (1). Múltiples estudios reportan que el sistema de conductos radiculares en la dentición temporal tiene una amplia gama de variaciones anatómicas impredecibles (2); Keerthana y cols., en un estudio publicado en el 2021, encontraron que un canal que se bifurca en el tercio apical es peculiarmente raro con solo dos casos reportados en la literatura (3).…”

“…El sistema de conductos radiculares puede tener una configuración diversa, haciendo fundamental la identificación precisa de la morfología y número de estos ya que compromete el éxito del tratamiento pulpar. La incidencia es baja ya que se reporta solo un 0,6 % la presencia de un conducto adicional en el incisivo central superior (3).…”
