A Deep Learning Model for Second-Molar Lesions Related to Impacted Third Molars.
Article in International dental journal, 2026. 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
objectivesThis study aimed to develop an automated deep learning (DL) system to detect and classify second molar (M2) pathologies associated with impacted third molars (ITMs) on panoramic radiographs. We sought to enhance diagnostic accuracy and support informed clinical decision-making.
methodsWe constructed a dataset of 1,170 panoramic radiographs that show second molars (M2s) adjacent to impacted third molars (ITMs). The cases were retrospectively divided into 4 groups: (1) no lesions; (2) caries (tooth decay); (3) external root resorption (ERR; loss of tooth root structure from external factors); or (4) both pathologies. Three oral surgeons, each with extensive experience, annotated the images using standardized criteria, resolving any disagreements by consensus. Our enhanced SMM-YOLOv8n model is based on You Only Look Once version 8 (YOLOv8) and features Slim-Neck optimization and multidimensional attention mechanisms. We trained the model with transfer learning (applying knowledge from pre-trained models to new tasks). We evaluated it using 5-fold cross-validation (dividing the data into 5 parts and rotating the validation sets).
resultsSMM-YOLOv8n achieved an mAP@50 of 0.886 on the internal test set. The macro-averaged precision, recall, and F1-score were 0.894, 0.96, and 0.926 (calculated at an IoU threshold of 0.5). These results show clear improvement over the baseline YOLOv8. For 60 images, the clinicians' mean sensitivity increased by 0.171, and the average interpretation time decreased by 8.79 minutes.
conclusionsSMM-YOLOv8n offers accurate and efficient detection of ITM-related M2 pathologies on panoramic radiographs. This approach may enhance early diagnosis, aid in treatment planning, and reduce the need for cone-beam computed tomography in initial assessments. CLINICAL SIGNIFICANCE: This DL-based diagnostic tool may serve as a valuable decision-support system, particularly in clinical settings with limited access to specialized dental expertise.
