Eapen Thomas 1 Department of Pediatric Dentistry, Meenakshi Ammal Dental College and Hospital, Chennai, India Many morphological variables have been identified both in primary and permanent dentitions. This report describes incidental finding of some uncommon dental traits like central accessory cusp or dens evaginatus, seventh accessory cusp in primary second molars and protostylid, triangular morphology of primary first molars. These characters have been amply documented in the permanent dentition. Presence of these extra cusps may have dental problems such as caries, sensitivity, occlusal interference and hence there is a need for continuous dental surveillance. http://pubs.sciepub.com/ijdsr/1/2/3/ijdsr-1-2-3.pdf dental traitsprimary dentitionaccessory cusp
