Radiomics analysis of panoramic radiographs using machine learning for the detection of peri-implantitis.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo develop and validate a deep-learning detection model (Mask R-CNN) and a complementary radiomics-based machine-learning analysis for peri-implantitis detection on panoramic radiographs.
methodsPanoramic radiographs from 144 patients (mean age 57.2 ± 11.7 years) were retrospectively collected. The peri-implantitis regions surrounding the implants of 144 patients were semi-automatically segmented by two dentomaxillofacial radiology residents. A total of 7,045 radiomic features peri-implant were extracted; 6 key features were selected via variance thresholding, SelectKBest, and LASSO regression. A Mask R-CNN (ResNet-50 backbone) was trained (80% train, 20% validation) with data augmentation. Diagnostic performance was assessed by FROC analysis and compared against six machine-learning classifiers.
resultsThe Mask R-CNN achieved an F1-score of 0.84 (95% CI 0.80–0.88) and AUC of 0.86 (95% CI 0.82–0.90) on the validation set. The best radiomics-based classifier (XGBoost) reached an F1-score of 0.84. Inter-observer ICC for segmentation was 0.97.
conclusionsRadiomics-enhanced deep learning can reliably detect peri-implantitis on panoramic radiographs. Prospective multicenter validation is warranted before clinical deployment.
