Microscopic root canal treatment of fused mandibular molar with seven root canals:a case report
摘要
Abstract
Fused teeth are usually formed by the partial or complete fusion of two normal tooth germs during the de-velopment process and belong to dental developmental abnormalities.Fused teeth are relatively rare clinically,and those occurring in the posterior tooth area are even rarer.This article reports a case of fused teeth between the first permanent molar and the second permanent molar in the right mandible.This fused tooth had a complex root canal anatomical struc-ture(seven root canals).The number and location of the root canals were analyzed by cone beam computed tomography,and root canal treatment was successfully completed with the assistance of microscope.关键词
