Abstract

Aim: This study aimed to evaluate the root canal anatomy of maxillary second premolars, and its relation to the maxillary sinus in a Saudi Arabian population using cone-beam computed tomography. Materials and methods: Records of 301 patients (602 Teeth) were obtained from a Cone-beam Computed Tomography Database of the College of Dentistry, Jazan University from February 2020 to January 2022. The number of roots, root canals, and the relationship between the root apices of maxillary second premolars and the floor of the maxillary sinuses were studied. The data was recorded, tabulated, and statistically analyzed. Results: A majority of maxillary second premolars were single-rooted (78.74%), followed by double-rooted (20.76%) and three-rooted (0.5%). Two canals (59.1%) were seen in the majority of the examined teeth, followed by one canal (40.4%) and three canals (0.5%). The roots of the maxillary second premolars were predominantly (69.17%) outside the sinus. Nineteen percent of roots were in contact with the floor of the maxillary sinus with no significant difference between buccal and palatal roots, and around twelve percent (11.73%) of roots were inside the maxillary sinus. Conclusions: The root canal system morphology of maxillary second premolars showed a wide range of anatomical variations in the Saudi Arabian population with a predominance of single roots. Most of the roots were located outside the sinus followed by in contact and then inside the sinus. Three-rooted second premolars were exceedingly rare. Clinical significance: The cognizance of maxillary second premolar root canal anatomy and its relation to maxillary sinus would be a valuable affirmation for dentists of different nationalities treating the Saudi Arabian population to ensure a successful endodontic treatment.
