Associations between odontogenic and sinus pathologies - a low-dose CBCT study.
Article in Acta odontologica Scandinavica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo evaluate maxillary sinus and odontogenic findings in low-dose CBCT, and to test if associations exist between these findings. Methods: From 263 consecutive CBCT scans, 212 were included. Evaluated odontogenic parameters were periapical lesions (PAI), marginal periodontal bone loss (PBL), root contact to the maxillary sinus, the presence of crowns, implants, defective restorations and extensive caries. Maxillary sinus findings were categorized as mucosal thickening (MT; generalized and localized), mucosal retention cysts, and opacification/fluid level. Crosstabulations and generalized estimating equations were used as statistical tests. Prevalence and bias adjusted kappas were calculated for inter- and intra-observer agreement.
resultsThe only dental finding statistically associated with sinus pathology when compared to healthy sinuses was root contact, which increased the risk for generalized MT (OR = 1.47, p = 0.015), mucosal retention cysts (OR = 2.60, p < 0.001) and opacification/fluid (OR = 1.76, p = 0.018). All parameters showed almost perfect or substantial intra- and interobserver reliability, except for PBL, where the former was moderate and the latter fair.
conclusionRoot contact was the only dental finding significantly associated with sinus pathology. Thus, there may be fewer associations between radiological dental findings and sinus pathology than previously thought. With the exception of PBL, all parameters demonstrated at least substantial intra- and interobserver reliability, indicating that the assessment is reliable overall.
