What was done
This narrative review summarizes the pathophysiological mechanisms of bacterial odontogenic sinusitis (ODS) originating from endodontic infections. The authors outline anatomical relationships between maxillary tooth roots and sinus cavities, microbial factors in root canal infections, and host immunological responses.
What was found
The abstract reports no original experimental or clinical data. It cites background literature indicating that 25% to 40% of chronic maxillary sinusitis cases are attributable to dental etiologies, with endodontic infection representing one of the most common causes.
Why it matters
It emphasizes the clinical importance of recognizing endodontic pathology as a frequent underlying etiology in chronic maxillary sinus disease, supporting interdisciplinary dental and otolaryngologic assessment.
Limits
The paper is an unsystematic narrative review providing no primary patient data, statistical analyses, or explicit inclusion/exclusion criteria for reviewed literature. All quantitative figures represent background citations from prior publications.
Cited by
- supports Failing root canals on upper molar teeth can allow bacteria to spread into the maxillary sinus cavity due to the proximity of the tooth apex to the sinus floor.
