Foreign bodies in maxillary sinuses are unusual clinical conditions, and they can cause chronic sinusitis by mucosal irritation. Most cases of foreign bodies in maxillary sinus are related to iatrogenic dental manipulation and only a few cases with non-dental origin are reported. Oroantral fistulas secondary to dental procedures are the most common way of insertion. Treatment is surgical remova...

BACKGROUND Bisphosphonates‎ inhibit osteoclasts, prevent bone resorption and decrease bone turnover. This study examined radiography finding in bisphosphonate-associated osteonecrosis of jaws. MATERIALS AND METHODS This is a retrospective series of 12 clinically diagnosed patients between 7 to 21 year old (average 13 years).

Actinomycosis is a chronic granulomatous infection caused by Actinomyces species which may involve only soft tissue or bone or the two together. Actinomycotic osteomyelitis of maxilla is relatively rare when compared to mandible. These are normal commensals and become pathogens when they gain entry into tissue layers and bone where they establish and maintain an anaerobic environment with exten...

Additionally, it is difficult to determine the size of the OAC clinically. If the communication is not diagnosed and managed properly, there is a risk that an epithelialized permanent oroantral fistula with resultant maxillary sinu...
