RESUMEN
@#The mandibular canine usually has a single root with a single canal. It is rarely to see a mandibular canine with two roots and two toot canals. A case of a patient who has a right mandibular canine with two roots and two root canals was reported. Cone beam computed tomography (CBCT) comprehensively demonstrated the root canal system and especially provided the information of canal varieties and complex canal before operation. CBCT can improve the discovery rate of canal varieties, guide root canal treatment and prevent missed roots in tooth extraction.
RESUMEN
A case of mandibular canine with apical periodontitis and double root canals was treated by CBCT assisted diagnosis and root ca-nal therapy.CBCT distinctly demonstrated the morphology of the root canal system in three dimensions and provided the information of canal varieties,prevented missed canals and conserved dentin.CBCT can guarantee the success of root canal therapy for the tooth with canal vareties.
RESUMEN
The number of root canals varies most in the areas of mandibular anterior teeth, maxillary and mandibular premolars, and premolars. Generally, The mandibular anterior teeth have one root canal, but data suggest that the anatomical morphology of the root canals of mandibular incisors varies greatly, which easily leads to the neglect of root canals in endodontic treatment. This report described the case of a mother and a daughter whose mandibular anterior teeth have two symmetrical root canals.
