Introduction:The purpose of this study was to investigate root canal morphology of maxillary second premolars in an Indian 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, 64.1% had one root canal at the apex and 35.4 % had two root canals at the apex. The average length of the teeth was 21.5 mm. Concerning the canal morphology, 33.6% of the teeth exhibited Vertucci type II configuration followed by type IV pattern (31.1%); 29.2% of the teeth possessed type I pattern. An additional canal configuration type XIX was found in one tooth. Isthmi and apical deltas was found in 19% and 14% of the cases, respectively.Conclusion:The root canal morphology of Maxillary second premolars can be complex and requires careful evaluation prior to endodontic therapy.

“…Anatomic variations of maxillary second premolars are well documented in the literature, however, trifurcated second premolars are rare. [27][28][29][30][31] (Table 2) Knowledge of such variation is crucial during endodontic treatment of the premolar which may necessitate modification of the typical access cavity and consequent technique of management. 28,32 Visualization of the third root (palatal root) of the premolar can be challenging on plain radiographs due to superimposition of the buccal roots.…”
