title: Endodontic treatment of bilaterally occurring 4-rooted maxillary second molars: case report.
abstract: The presence of 4-rooted maxillary second molars has been described in only a limited number of case reports. Studies of anatomical features have demonstrated substantial variation in the number of roots and root canals in different teeth. The maxillary second molar usually has 1, 2, or 3 roots and generally 3 or 4 root canals. This case describes the presence of 4 roots occurring bilaterally in maxillary second molars in one patient.
