According to the high number of articles published on invasive cervical resorption (ICR), this pathology, as commonly believed, is a more frequent form of cervical resorption. ICR is often misdiagnosed as internal resorption or caries, which leads to inappropriate treatment and even unnecessary tooth loss. Despite a correct diagnosis, the treatment of this type of hyperplastic invasive external resorption poses a challenge for the clinician.

Introduction: We investigated the root canal configuration of maxillary premolars in a Spanish population by using cone-beam computed tomography.

Methods: Images of 804 maxillary first and second premolars were obtained from 620 patients who underwent cone-beam computed tomography scanning during preoperative assessment (before implant surgery, orthodontic treatment, dentoalveolar trauma diagnosis, or difficult root canal treatment). We determined tooth position, number of roots, root canal configuration (Vertucci's classification), number of root canals, and number of apical foramina per root and used the χ(2) test to analyze the correlation between root number and tooth position.
