Reactive Lesions Of Oral Cavity.

Oral mucosa is subjected constantly to external and internal stimuli that can give rise to reactive lesions. These lesions are non- neoplastic in nature. They manifest a spectrum of diseases that range from developmental, inflammatory, and reactive to neoplastic changes. Reactive lesions are typically gives response to chronic inflammation caused by various forms of low grade chronic irritations to the oral mucosa such as dental plaque and calculus, sharp edges of grossly carious teeth, faulty dental restorations, chronic biting habits, ill-fitting dental/oral appliances and food impactions. These lesions have a very similar appearance to benign neoplastic proliferations. This similarity is troublesome in differential diagnosis among them. Different types of localized reactive lesions of oral cavity are focal fibrous hyperplasia (FFH), pyogenic granuloma (PG), irritational fibroma, peripheral giant cell granuloma (PGCG), peripheral ossifying fibroma (POF), fibro-epithelial hyperplasia/polyp, inflammatory fibrous hyperplasia, and inflammatory gingival hyperplasia.

Trabecular Juvenile Ossifying Fibroma in A 13 Year Old Boy– A Case Report.

Juvenile ossifying fibroma (JOF) is an uncommon, benign, bone‑forming neoplasm with an aggressive local growth that is distinguished from other fibro‑osseous lesions primarily by its age of onset, clinical presentation and aggressive behaviour. JOF is considered as a variant of the ossifying fibroma (OF) and the former includes psammomatoid JOF (PsJOF) and Trabecular JOF (TrJOF). Both variants involve the craniofacial bones with the trabecular variant being more common in the jaws and the psammomatoid variant being more common in the craniofacial skeleton. TrJOF is a unique variant of JOF. We report a rare case of massive TrJOF involving the maxillary sinus in a 13‑year‑old male.

Tricho dento osseous syndrome.

Tricho-dento-osseous dysplasia is a rare autosomal dominant disorder which involves increased bone density, enamel hypoplasia, enlarged pulp chambers, and molar taurodontism. We report a case of a 12 year old female presenting with tricho dento osseous syndrome.
