The global prevalence of maxillary sinusitis of odontogenic origin (MSOO) is still unknown. Therefore, this study aimed to determine the combined prevalence of MSOO and verify the associations between different odontogenic conditions and MSOO.
Methods
Six electronic databases and gray literature were searched on August 25, 2022. Two independent reviewers selected observational studies reporting the prevalence of MSOO and associated conditions in adults.
Studies that did not use computed tomography for diagnosis were excluded . The methodological quality of the studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Cross-Sectional Studies.
Data were analyzed using proportion and association meta-analysis. The certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach .
Results
Thirty-eight studies were included in the qualitative analysis and thirty-one in the meta-analyses. Only 12 studies (31.6%) met all items of the methodological quality checklist.
In general, studies reported prevalence measures per maxillary sinus or patient. Therefore, the pooled prevalence of MSOO was 51% per breast (95% confidence interval [CI] [40%–61%]) and 50% per patient (95% CI [41%–59%]). ]).
Apical lesion (odds ratio [OR]: 4.03, 95% CI [2.26–7.19]), periodontitis (OR: 5.49, 95% CI [2.27–13.24]), moderate (OR: 2.57, 95% CI [1.85–3.57]) and severe bone loss (OR: 13.80, 95% CI [2.81–67.85] were significantly associated with MSOO The certainty of the evidence for associations was very low.
Conclusions
- The combined prevalence of MSOO on CT evaluation was 51% per maxillary sinus and 50% per patient.
- Therefore, half of maxillary sinusitis may be of odontogenic origin.
- Apical lesion, periodontitis, and moderate and severe bone loss were significantly associated with MSOO.
