Abstract

Hypodontia is defined as the absence of one or a couple of teeth. It has been regarded as the most frequent dental developmental anomalies among humans. Agenesis of mandibular second premolar is the most common anomaly. In the congenital absence of permanent second premolar the management of retained primary second molar (PSM) could be challenging. The present case series report contains the endodontic treatment of two infected mandibular PSM that has developed a peri-apical lesion. Owing to the agenesis of the permanent successor tooth, during endodontic preparation the tooth was disinfected and also in the subsequent session the root canal system was filled with gutta purcha point followed by crown placement. 12 months of follow-up revealed that the tooth was symptomless as well as brought back to function, also lamina dura re-establishment and inter-radicular bone lesions healing was seen, indicating successful treatment.
