Abstract

The main goals of root canal therapy are to relieve pain, eliminate infections from the root canal system, and prevent future infection. The maxillary second molars typically present with three roots and contain three to four canals; however, anatomical variations frequently observed. Failure to identify these variations can complicate the procedure, emphasizing the importance of precise radiographic assessment. Cone beam computed tomography (CBCT) has demonstrated superior effectiveness compared to conventional radiography in assessing root canal morphology. This paper reports a maxillary second molar with unusual root morphology having two palatal roots. CBCT confirmed this diagnosis.
