Characteristics and risk factors in odontogenic maxillary sinusitis from different dental infections: a retrospective study based on sinus CT imaging.
Article in BMC oral health, 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
backgroundOdontogenic maxillary sinusitis is a common type of maxillary sinusitis, which is secondary to adjacent infectious maxillary dental lesions. However, the prevalence and the different odontogenic risk factors that influence the pathogenesis of odontogenic maxillary sinusitis are not clear. Thus, odontogenic maxillary sinusitis is often overlooked and facing great difficulties of multi-disciplinary treatment decisions for odontogenic maxillary sinusitis. The objective of this study was to analyze the different dental potential risk factors of odontogenic maxillary sinusitis and optimize dental decision-making of odontogenic maxillary sinusitis, which finally provides evidence-based options for multi-disciplinary treatment.
methods968 patients diagnosed with maxillary sinusitis were included based on sinus Computed Tomography, among which 261 patients were categorized as odontogenic maxillary sinusitis. The maxillary sinus and ostiomeatal complex Lund-Mackay score were used to evaluate the severity of sinus infection. Different dental lesions and relevant risk factors that may impact the severity of maxillary sinusitis are systematically evaluated with radiologic data. P < 0.05 were considered statistically significant.
resultsThe prevalence of odontogenic maxillary sinusitis in maxillary sinusitis patients was 26.96% and in odontogenic lesions present simultaneously with unilaterally maxillary sinusitis reached up to 79.63%. The Lund-Mackay score of odontogenic maxillary sinusitis was significantly higher than that of non-odontogenic maxillary sinusitis. The first molar involved accounts for the highest tooth position in odontogenic lesions. The highest incidence of dental origin was peri-root origin, followed by apical origin and oral-antral fistula. The maxillary sinus Lund-Mackay score was significantly increased when the distance between the maxillary sinus floor and the odontogenic lesion was less than 3.32 mm. When the maxillary sinus floor bone was discontinuous, peri-root origin lesions led to a higher ostiomeatal complex Lund-Mackay score.
conclusionOdontogenic 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.
