Description
Original diagnose after Case (1980) p. 79 [390]: Anterior teeth of a juvenile, crown height approximately 2 mm, and width of the teeth across the three cusps, approximately 2 mm, partially fragmented teeth, missing small portions of the enameloid coating on the lower margins of the crowns, most evident on the labial views, where the central lower portion and the left lower apron of the teeth are missing, while on the lingual sides, the dentinous material is spongy.
