BACKGROUND: THE CBCT TECHNOLOGY HAS A VERY EXCELLENT SPATIAL RESOLUTION IN ALL PLANES WITH HIGH QUALITY, minimizes the acquisition time, lowers radiation doses and it’s proved for the variability and complexity of the anatomy of the root canal system premolar teeth. The aim of this cross-sectional study was to discover root canal morphology of premolar teeth regarding Vertucci and Weine classification and also to determine number of roots and location of apical foramen among population in Kurdistan region of Iraq.

Methods: One hundred and three images taken of maxillary and mandibular first and second premolars through the CBCT technique were analyzed. The images were taken from private dental clinics and were collected for the study analysis between November 2021 and May 2022 according to inclusive criteria.

Results: In accordance to Vertucci classification despite to maxillary first premolar teeth type IV was the commonest type (26.0%) and in maxillary second premolar teeth type II is the highest rate (12.0%) and whereas for mandibular first and second premolar teeth type I is the most prevalent type (18.0%), (17.0%) respectively. Regarding to Weine classification for maxillary first premolar teeth type III was the most prevalent type 26.0%, in maxillary second premolar teeth type II is the highest rate (12.0%), Whereas to mandibular first and second premolar teeth type I is the most common (18.0%), (17.0%) respectively. According to root numbers for maxillary first premolar teeth two rooted number is the highest rate (26.0%) and for maxillary second and mandibular first and second premolar teeth one rooted teeth are the commonest root number (19.0%), (20.0%), (26.0%), respectively. Despite to the location of apical foramen for all maxillary and mandibular first and second premolar teeth the center location is the most prevalent location (15.0%), (16.0%), (15.0%), (15.0%), respectively.

Conclusions: This cross-sectional study illustrate that the type IV is the most widespread for maxillary first premolar teeth, and type II to maxillary second premolar teeth and for mandibular first and second premolar teeth type I is the most common type. But in Weine classification for maxillary first premolar teeth type III was the most widespread type, for maxillary second premolar teeth type II and in mandibular first and second premolar teeth type I is the most common type. Regarding number of roots, in maxillary first premolar teeth two rooted teeth are more common but in all maxillary second and mandibular first and second premolar teeth one rooted teeth is the most prevalent root number. About the location of apical foramen, the center is the highest ratio among all the other locations for premolar teeth.
