Evaluation of canal configuration and frequency of second canal in mandibular lateral incisor using Cone Beam Computed Tomography (CBCT)

Objective: To categorize root canal configuration according to Vertucci’s classification and determine the frequency of second in mandibular lateral incisors Pakistani subpopulation (Karachi based) by using Cone Beam Computed Tomography.
 Study Design: Cross sectional study.
 Place Duration Study: Out-patient department Oral Maxillofacial Surgery Radiology at Dow University Health Sciences, Karachi Pakistan, from Jan Jul 2019.
 Methodology: was conducted on 160 extracted permanent incisors. After extraction, teeth were randomly arranged wax models imaged via CBCT. Each tooth sample analyzed axial sagittal sections. The images investigated two blinded examiners data morphology recorded.
 Results: single recorded as 107 (66.9%) whereas 53 (33.1%) showed canals. Females presented with a higher canalled incisors, although results statistically insignificant. most prevalent anatomy detected Type I (105, 65.6%) followed III (33, 20.6%), II (12, 7.5%) V (10, 6.3%). Mandibular presenting canals anatomy, (32, 97%) commonly 100%) (9, 90%).
 Conclusion: CBCT scans are an effective tool for identification morphology. frequently configuration.
