Successful treatment of osseous lesion associated with palatoradicular groove using local drug delivery and guided tissue regeneration: A report of two cases.

Developmental grooves are not rare and often appear on maxillary lateral and central incisors and are an important predisposing factor to localized periodontal disease. Various techniques have been adopted to eliminate the groove and regenerate lost periodontium. This report of two cases describes the technique of using the local drug delivery system with chlorehexidine and the guided tissue regeneration (GTR) to control the disease progression and regeneration.

Fusion of complex odontome with permanent mandibular molar.

Odontomas are malformation of the dental tissue, arising during normal tooth development. They are usually asymptomatic, but often associated with tooth eruption disturbance. This article reports a case of complex odontome in a 23-year-male, which hampered the eruption of mandibular right second molar as well devitalization of first molar.
