DIAGNOSIS AND ROOT CANAL TREATMENT OF MANDIBULAR 2ND PREMOLAR WITH TWO ROOTS -A CASE REPORT

Abnormalities in the root canal anatomy are commonly occurring phenomenon. A thorough knowledge of root canal anatomy and its variation is necessary for successful completion of endodontic treatment.Mandibular premolar is known for having aberrant anatomy. Often considered an enigma to endodontits, the mandibular premolar with dual canal dividing at various levels of the root can generate complex mechanical problems. The role of genetics and racial variations may result in difference of incidence of root number and canal number. This paper attempts at explaining a rare case of successful endodontic management of two rooted mandibular 2nd premolar with awareness of data  pertaining to number of canals, knowledge of canal morphology, correct radiographic interpretation and tactile examination of canal wall which are important in detecting the presence of multiple canals.
Key Words - Mandibular second premolar, two roots, Modified access cavity
