Protostylid: A case series
A 6-year-old South Indian girl came for routine dental checkup to the Department of Pediatric Dentistry. Family and medical histories were non-contributory. There was no reported history of orofacial trauma. Extra oral examination revealed no abnormalities. Upon intra oral examination, no soft-tissue abnormalities were observed except mild gingivitis. A bilateral protostylid was present on the buccal surface of the maxillary right and left first primary molars viewed in the frontal plane []. Protostylid, which is present on the left side, presents a free cusp apex that doesn’t reach the occlusal plane. Indeed, the protostylid is out of function since there is no occluding anatomical structure on the opposing mandibular arch. On buccal view, protostylid constitutes a conical shape, which was measuring about 3 mm cervico-occlusally and 3 mm mesio distally. Triangular prominence with its base below the gingival margin and its apex oriented occlusally. Protostylid on the maxillary right first primary molar was not prominent.
