title: Evaluation of horizontal/oblique root fractures in the palatal roots of maxillary first molars using cone-beam computed tomography: a report of three cases.
abstract: Diagnosis of root fractures is generally based on clinical and radiographic presentations. This case report aims to detect horizontal/oblique root fractures in posterior teeth using a combination of conventional radiographs and cone-beam computed tomography (CBCT). Three maxillary first molars with horizontal/oblique root fractures in the palatal roots are presented. More detailed information on root fractures can be obtained using CBCT compared with conventional radiography. As such, CBCT might be a useful complementary diagnostic method to conventional radiography in cases of suspected horizontal/oblique root fractures.
