ABSTRACT

Nevus of Ota is a benign dermal melanocytosis, that involves facial skin as a macular discoloration, appearing as blotchy blue to blue gray. It involves the upper portion of the face, especially over the periorbital area. It also involves ocular structures such as episclera, sclera, conjunctiva, cornea, retina, uveal tract and also nasopharynx, auricular mucosa, tymphanic membrane and dura. Glaucoma and malignant melanoma are the two known ocular complications in patients with Nevus of Ota. 12-18% of these patients exhibits palatal pigmentation. Here we are reporting two cases of Oculodermal melanocytosis, one of which exhibited palatal pigmentation.

ABSTRACT

Dens invaginatus is a deep surface invagination of the crown or root that is lined by enamel. It is one of the developmental anomalies affecting the teeth. It commonly affects maxillary lateral incisor, followed by central incisor, premolar, canine and molar tooth. Maxillary teeth are more commonly involved than mandibular teeth. It usually occurs unilaterally although 43% occur bilaterally. The invagination within the tooth can be single, double and even triple has been reported. The affected tooth usually is thick, barrel shaped with a small round palatal opening to the invagination. It usually traps plaque, food debris and is prone for dental caries, which may lead to pulpal and periapical pathology. So if detected early the dens invaginatus should be prophylatically restored. Two unilateral and one bilateral case of dens invaginatus are reported here.
