Automated differentiation of caries requiring filling and caries necessitating root canal treatment using machine learning.
Article in Oral radiology, 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
objectivesNovice dentists or those at the onset of their professional careers require assistance in diagnosing cases that necessitate fillings or root canal treatments. In this study, we propose an innovative recommendation system based on deep learning to assist dentists in identifying the type of tooth caries (requiring filling and necessitating root canal treatment) and determining the appropriate treatment for detected caries. Correctly identifying the type of caries in teeth with no caries, only one type of caries, or more than one type of caries is important for determining the type of treatment to be applied.
methodsWe utilized 1253 bitewing images augmented with various variations, employing three different segmentation methods to automatically detect caries types in the first molar teeth. Furthermore, this study introduces a novel recommendation system for determining the treatment type required for the detected caries type, which represents a significant contribution to this field. The YOLOv8, U-Net, and Detectron-2 networks were evaluated for their efficacy in detecting various types of caries and recommending appropriate treatment methods.
resultsThe pixel-label-based comparative results generated by these methods on data labeled by experienced dentists were as follows: 95.03% for Detectron2, 90.88% for U-Net, and 89.23% for YOLOv8. The determination of the type of caries and the recommendation of the type of treatment differ from each other. In terms of treatment recommendations, the success rates of the three methods were as follows: Detectron-2, 88.09%; YOLOv8 70.23%; and U-Net, 61.90%. Consequently, Detectron-2 produced the most successful outcome among the three methods. These results are acceptable for the auxiliary treatment recommendation system.
conclusionThe system can serve as a supportive tool for less-experienced dentists and as a diagnostic aid for experienced practitioners. The learning-based segmentation method shows great promise for clinical use in the recommendation of treatment.
