Keywords: First premolar | Mandibular | Maxillary | Vertucci’s classification | Spiral computed tomography.

The present study was carried out to observe root canal variations in maxillary and mandibular first premolarteeth in the local population using spiral computed tomography. Sixty, each of well formed maxillary and mandibular firstpremolar teeth without any carious lesions were used in this study. They were placed in 5% sodium hypochlorite solutionfor 30 minutes for the removal of organic debris. They were then stored in normal saline till further experiment was carriedout. Each tooth was scanned with a slice thickness of 0.625 mm. Data collected was used to reconstruct the scanned teeththree dimensionally. The configuration seen in longitudinal and transverse sections was used to classify the canal anatomyaccording to Vertucci’s classification.
