PREVALENCE OF MAXILLARY SECOND PREMOLAR TEETH WITH 2 CANALS IN SAUDI POPULATION OF EASTERN AND SOUTHERN REGIONS
Abstract
Aim: The aim of this study is to increase the practitioner’s awareness of the possibility of 2 canals of upper second premolar teeth during endodontic treatment that helps to avoid failure of RCT caused by missing one of the main canals.
Methodology: It is a cross-sectional study was conducted in 2 different regions east and south regions of Saudi Arabia. Data collected from randomized patients sample of armed forces hospital southern region and from Dammam medical complex- dental department (ministry of health) in eastern region including male and female with age between 15-45 y/o, by using Chi-square test. 140 patients were selected for the study (95 patients in the southern region and 45 patients in eastern region). They were examined clinically and radiographically. Results: Out of 140 patients, 79 patients (56%) have 2 canals in the upper second premolars and 61 patients (44%) have 1 canal in the upper second premolars In eastern region, out of 45 patients, 26 patients (57.77%) have 2 canals in the upper second premolars and 19 patients (42.33%) have 1 canal in the upper second premolars. In the southern region, out of 95 patients, 53 patients (55.78%) have 2 canals in the upper second premolars and 40 patients (44.22%) have 1 canal in the upper second premolars.
Conclusion: This study showed close proportions in the probability of two canals of upper second premolar teeth in both eastern and southern regions of Saudi Arabia. So, the dentists should be aware that the percentage of two canals in upper second premolar teeth almost reaches more than 50% while doing root canal treatment.
