RESUMO
Talon cusps in anterior teeth are relatively rare developmental anomalies. They are characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or cementoenamel junction. Facial talons occur very rarely; <10 cases have been described in the literature. This article attempts to describe the variants of this anomaly with 2 case reports involving facial and bilateral palatal manifestation.

Unicystic ameloblastoma (UCA) is a cystic lesion that shows clinical, radiographic, or gross features of an odontogenic cyst, but reveals a typical ameloblastomatous epithelium lining in the cyst cavity, with or without luminal and/or mural tumor growth. This article reports the case of a 22-year-old man with dull intermittent pain and swelling in the mandible. Histopathological examination revealed a UCA of a luminal, intraluminal, and intramural histological subgroup, which has a high risk for recurrence.

BACKGROUND: Quid chewing practice has been a part of our tradition since centuries with little known evidence of oral cancer. However, recent trends show a rise in occurrence of oral cancer often associated with tobacco and arecanut usage. Ascorbic acid is an important salivary antioxidant. Betel leaf which is used in quid is known to contain ascorbic acid. AIM: The aim of our study was to assess the salivary levels of ascorbic acid in traditional quid chewers so as to determine whether the betel leaf has protective antioxidant action. MATERIALS AND METHODS: Salivary ascorbic acid levels of 60 subjects were estimated using the Dinitrophenyl hydrazine method. RESULTS: The results revealed that quid chewers who used betel leaf had higher salivary ascorbic acid content compared to nonbetel leaf quid chewers. This could possibly be due to the protective antioxidants in the betel leaf.
