RESUMO
An unusual case of impacted and inverted maxillary central incisor is reported in a 12 year old girl. The inverted maxillary central incisor was not associated with any other anomaly which is rare.
RESUMO
Abnormalities in the root canal anatomy are a commonly occurring phenomenon. A thorough knowledge of the root canal anatomy and its variations is necessary for successful completion of the endodontic treatment. Mandibular second premolars usually have a single root and a single root canal. The incidence of two separate roots itself in this tooth is quite rare. Mandibular premolars are known for having an aberrant anatomy. Often considered an enigma to the endodontist, the mandibular first premolar with dual canals dividing at various levels of the root can generate complex mechanical problems.Reports about the incidence of extra roots in these teeth are quite rare. This paper attempts at explaining a rare case of successful endodontic management of a two-rooted mandibular second premolar with awareness of data pertaining to the number of canals, knowledge of canal morphology, correct radiographic interpretation, and tactile examination of canal walls which are important in detecting the presence of multiple canals.
