Abstract
Introduction: Successful root canal treatment depends on thoroughly understanding root canal morphology. Variations in this anatomy are common and can significantly impact treatment outcomes. This study aimed to investigate the prevalence of root and canal configurations in maxillary premolars and their association with age, gender, and jaw side in a specific Iranian population.
Methods: A cross-sectional study analyzed CBCT images of maxillary premolars from patients treated at oral and maxillofacial radiology clinics in Rasht City, Iran, between 2021 and 2022. Root number and canal morphology (Vertucci classification) were determined. Statistical analysis assessed associations between these variables and age, gender, and jaw side. The significance level of the tests was set at 0.05.
Results: A total of 1732 maxillary premolars were analyzed. Maxillary first premolars showed a nearly equal distribution of single- (46.1%) and double-rooted (52.9%) teeth, while maxillary second premolars were predominantly single-rooted (91.1%). Vertucci types II and IV were most frequent in single-rooted maxillary first premolars, while type I predominated in second premolars. A statistically significant association was found between canal morphology and both gender (p < 0.05) and age (p < 0.05), but not jaw side. Males had a higher frequency of multi-rooted teeth, and canal complexity increased with age.
Conclusions: This study provides valuable data on maxillary premolars' root and canal morphology in a specific Iranian population. The findings highlight significant morphological variations related to tooth type, gender, and age affecting endodontic treatment planning. Pre-operative CBCT assessment may improve treatment outcomes
