ABSTRACT:Comprehensive knowledge about the variations of morphology and anatomy of the roots and root canal systems in permanent teeth is an important factor to reach successful outcome. The aim of this case report was to explain nonsurgical endodontic treatment and long term follow-up of a mandibular second premolar with unusual root and root canal morphology. 10-year-old girl was referred with a complaint of severe toothache in her right mandibular second premolar tooth. During the endodontic treatment, it was observed by the radiographic evaluations that the tooth had three roots and four canals. In the 36th month follow-up session, complete healing of the tooth was determined. It was concluded that the variation of the mandibular second premolar tooth in the present case has never been reported. Therefore, the present case may be considered as a rare case by its unusual root and root canal morphology.
