ABSTRACT – ENDODONTIC MANAGEMENT OF MAXILLARY SECOND MOLAR HAVING MB2 CANAL: A CASE REPORT

ABSTRACT
The main objective of root canal treatment is to relieve pain, disinfect root canal and prevent reinfection. To achieve clean, disinfected and 3-dimensionally obturated root canals, clear knowledge of root morphology and canal anatomy is essential. Awareness and understanding of the presence of unusual external and internal root canal morphology contributes to successful outcome of the root canal treatment. Maxillary second molars show considerable anatomic variation and abnormalities with respect to the number of roots and root canals. Undetected extra roots or root canals are a major reason for failure of root canal treatment. Presence of a second canal in mesiobuccal root (MB2) of maxillary molars is well documented in the literature. Various studies have shown that occurrence of MB2 root canal is found to be more in maxillary first molars than maxillary second molars. Accurate radiographic technique and proper interpretation are essential for sound diagnosis and treatment. The use of preoperative radiographs at different angles helps to detect and evaluate root canal morphology and anatomy. CBCT is a method of choice to visualize extra number of roots and root canals. Other devices like magnifying loupes and dental operating microscope can also be used to detect extra canals
