A deep learning approach to predict the results of root coverage procedures based on intraoral photographs: a retrospective study.
Article in BMC oral health, 2025. 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
backgroundGingival recession (GR) occurs frequently in patients with periodontitis. The prediction of post-operative gingival margin (GM) holds significant importance for the development of surgical plans. The accuracy of the prediction of the root coverage procedures can be influenced by the periodontists' subjective bias and the complex anatomical factors of the affected teeth. Deep learning network may improve the accuracy and efficiency of the prediction of the root coverage procedures. This study aims to establish a deep learning model based on intraoral photographs, which could accurately predict the results of root coverage procedures.
methodsA total of 963 teeth (408 intraoral photographs) were included to construct the model. A deep learning model based on YOLO-v8 was proposed to annotate the papilla zeniths (PZ), mesial and distal contact points (CP), cemento-enamel junction (CEJ), and point angles (CPA) on each tooth, to predict the maximum root coverage (MRC). The differences between the manually annotated and the model-predicted key points were calculated to evaluate the accuracy of the model. Another 114 teeth (50 intraoral photographs) 6-month postoperative were included in this study to validate the accuracy of the model on real clinical cases.
resultsThe mean radial error (MRE) for all key points detections was 2.19 pixels, and the standard radial error (SRE) was 3.72 pixels, the MRE between manually annotated and model-predicted key points ranges from 0 to 8 pixels. In real cases, the MRE between the manually annotated GM and the model-predicted MRC was 0.91 pixels, the SRE was 1.32 pixels.
conclusionsThe model constructed in this study could accurately predict the results of root coverage procedures, thereby enhance clinicians' clinical decision-making and facilitate doctor-patient communication.
