Adel Al Obiad | Suheel Manzoor Baba

Abstract: Knowledge of the root canal morphology and the possible anatomical variations of mandibular premolars are important for the successful endodontic treatment. The aim of this study was to evaluate the variation in morphology of root canals in mandibular premolars in patients from asir region of Saudi arabia. Methodology One hundred and ten human mandibular premolars (36 first premolars and 74 second premolars) from patients requiring endodontic treatment were involved in this study. After access the cavity of the teeth, the root canals were explored and radiographs were taken. Results Premolars with one canal were found in 91of cases (30 % first premolar and 61 % second premolar) and premolars with two canals were found in 8 % of cases (3 % first premolar and 5 % second premolar). There was just one case (1 %) where a first premolar had three canals. These differences were statistically significant with P<0.05. Conclusion Clinicians should be aware of the root canal variation in the mandibular premolars and be able to apply this knowledge in radiographical and clinical interpretation.
