Abstract

The present article shows the occurrence of a rare dental morphological trait, “protoconidal cingulum” or “protostylid” on the buccal surface of permanent mandibular first molar in a 14 year old Indian male patient. This morphological dental variation was reported more frequently in primary dentition involving second molars. Prevalence, clinical implications, classification systems and various nomenclatures pertaining to protostylid is discussed in this paper.
