ABSTRACT

Objective: To evaluate the frequency of root canal morphological patterns of mandibular first premolars analyzed by cone-beam computed tomography (CBCT) scans among patients reported to a dental hospital in Islamabad

Study Design: Retrospective cross sectional analytical study.

Place and Duration: From 1^st January 2018 to 31^st December 2019 at Operative Dentistry Department in Islamic International Dental Hospital, Islamabad.

Methodology: Cone-beam computed tomography (CBCT) scans (PLANMECA, Finland) were used with image size 13 x 9cm (651 x 651 x 451 cm³), voxel size 200μm to include mandibular anatomy with 96 KV radiation dose, exposure time of 12.078 seconds and current of 9 MA. Slice thickness of 0.200mm was recorded. Axial, coronal and sagittal planes were used to evaluate root canal anatomy of mandibular first premolars. Root canal configurations as per Vertucci’s classification were recorded.

Results: Out of 150 cone-beam computed tomography (CBCT) scans, 206 mandibular first premolars met the inclusion criteria. Total number of teeth having one root and one canal was 99.03%, whereas teeth having two roots and two canals were two and probability of such morphology was very rare i.e. 0.97% only. The most common type of morphology on the basis of Vertucci’s classification was type I i.e. 87.4% followed by type V in 9.18%, type III in 2.42%, type IV in 0.96% of the subjects. 

Conclusion: In a sample of patients visited a dental hospital, majority of mandibular first premolars had one root and type I canal configuration. No significant difference was found between gender and root canal morphology. CBCT is a reliable tool in assessing root canal morphology.
