DENS IN DENTE:
PRIMARY TOOTH
Report of a Case BERNARD

D.D.S.,* Los ANGELES, CALIF.
dens in dente are comparatively common in permanent teeth, WL.HILE none have been reported in primary teeth. K., a white boy, aged 3 years, 5 months, presented himself to the office on March 5, 1951. He complained of pain and swelling in the upper left primary cuspid area. On clinical examination the tooth presented an atypical appearance. The labiolingual diameter was greater than normal. The enamel seemed hypoplastic with a deep groove in the coronal portion. The area above the apex was highly inflamed and swollen. The tooth was sensitive to percussion and palpation and was mobile.

Roentgenographic studies at varying angles revealed two distinct root canals and a short accessory root. Part of the floor of the pulp chamber was lined with a radiopaque layer. Because of the periapical infection the tooth was removed and a ground section was made. The section was made to show the invagination, pulp area *Diplomate American Board University of Southern California.

and enamel lining the pulp similar to the pattern in the classic description of dens in dente of Tomes (1859) and Miller (1901), as quoted by Thoma. The tooth was diagnosed as a dens in dente of the upper left primary cuspid because of the histologic evidence. Fig. 1 is an x-ray of the upper left primary cuspid showing 2 distinct root canals in the main root portion. It also shows an accessory root and typical coronal invagination of dens in dente. Fig. 2 is a histologic ground section of the upper left primary cuspid, a dens in dente. D, dentine; E, enamel; I, invagination. Fig. 3 is a high-power photomicrograph of marked area in Fig. 2. D, dentine; E, enamel; P, pulp. A survey of the literature reveals no previous cases reported in primary teeth though quite a number of investigators have reported dens in dente in permanent teeth.
