Characteristics and risk factors in odontogenic maxillary sinusitis from different dental infections: a retrospective study based on sinus CT imaging

Odontogenic maxillary sinusitis has more severe pathogenesis than non- odontogenic maxillary sinusitis and accounts for 26.96% of maxillary sinusitis. The distance between the sinus floor and the odontogenic lesion, and also the type of odontogenic lesions are important risk factors in the severity of odontogenic maxillary sinusitis, which provided new references for guiding the clinical diagnosis and dental treatment of odontogenic maxillary sinusitis.
