title: Endodontic therapy in a maxillary second molar with three buccal roots.
abstract: In this study, we report a case of a four-rooted maxillary second molar in which three well-separated buccal roots were located. This case demonstrated that even though it is not common, an extra root containing an independent root canal may occur.
