Microradiographic description of a crown dilaceration.
A case of a crown dilaceration in an upper permanent incisor of a 6-year-old child is described. Microradiographs of sagittal sections demonstrated that enamel was broken into fragments which differed on the vestibular and palatal sides. A study of the structural lines in the dentin layer and the disposition of the enamel fragments permits consideration of the lesion as a consolidated fracture.
