[Diagnosis and management of sinusitis of odontogenic origin].
Maxillary sinusitis are common infections. A dental origin is found in about 10% of the cases. The roots of the posterior maxillary teeth are adjacent to the sinus floor. Extensions of dental infections are therefore possible to the sinus. An odontogenic source should be considered in patients with a history of dental pain or recent oral surgery and those with extended unilateral sinusitis or unilateral sinusitis resistant to conventional treatment. Maxillary sinusitis of dental origin are polymicrobial infections. Conventional radiographs and CT-scans are required for the diagnosis and proper management. Dental treatments to remove the underlying cause combined with oral antibiotics to treat the infection are required. Endoscopic or open surgery may be necessary to complete the treatment and restore adequate sinusal function.
