Introduction: The aim of this study was to investigate root canal morphology of maxillary second premolars in Kashmir population. Materials and Methods: Two hundred maxillary second premolars were collected, stained, decalcified, and cleared. Cleared teeth were examined in a steromicroscope under 7.5× magnification and the following observations were made: (1) length of the teeth, (2) number of root canals, (3) root canal configuration by Vertucci’s classification, (4)number of isthmi between the canals, (5) frequency of apical deltas. Results: Of the two hundred maxillary second premolars, 61.5% had one root canal at the apex and 32.5 % had two root canals at the apex. The average length of the teeth was 20.5 mm. Concerning the canal morphology, 34% of the teeth exhibited Vertucci type II configuration followed by type I  29.5% and  type IV pattern (27.5%). Isthmi and apical deltas was found in 14% and 12% of the cases, respectively. Conclusion: The root canal morphology of Maxillary second premolars can be complex and requires careful evaluation prior to endodontic therapy.
Key words: Apical delta; decalcification and staining; maxillary second premolar; root canal morphology; Vertucci’s classification.
