Factors influencing submandibular fossa visibility on panoramic images: a comparative CBCT study.
Article in BMC oral health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThis study aimed to investigate the variables affecting the visibility of the submandibular fossa (SF) on panoramic images, including SF depth and types, age, gender, presence or absence of tooth, location of mandibular canal, and alveolar bone thicknesses.
methodsCone beam computed tomography (CBCT) images and conventional panoramic images of 150 patients were analyzed retrospectively. The visibility of the SF on panoramic images was compared with its depth and adjacent alveolar bone thicknesses on CBCT. Predictive variables affecting the SF visibility were identified, and binary logistic regression analysis was performed.
resultsBased on CBCT measurements, the SF depth was ≥ 2 mm in 65% of the hemi-mandibles with radiolucent area (26.7%). A significant difference was observed between the SF visibility on panoramic images and its depth, and the lingual cortical bone thickness as measured on CBCT. When the SF was visible and not, the mean SF depth was 2.24 ± 0.97 mm and 1.6 ± 0.8 mm, and lingual cortical bone thickness was 1.27 ± 0.47 mm and 1.53 ± 0.49, respectively. Regression analysis revealed significant associations between SF visibility and gender (Odds ratio (OR) = 3.28, 95% confidence interval (CI): 1.77-6.09), age (OR = 0.96, 95% CI: 0.94-0.98), SF depth (OR = 2.01, 95% CI: 1.43-2.81), and lingual cortical bone thickness (OR = 2.02, 95% CI: 1.30-3.16).
conclusionsA prominent radiolucent SF on panoramic images indicates a deeper fossa and thinner lingual cortical bone, necessitating caution by clinicians during surgical planning.
