In dental radiology, previous studies applied deep learning models for caries detection and classification on different image modalities8,9,10,11,12,13,16. Today, dental caries is accepted as an imbalance in the biofilm-induced cyclic process of demineralization and remineralization of tooth structure, by the acidic by-products resulting in a pH maximal drop followed by the return of the pH to initial pH modulated by saliva. This situation may lead . You are using a browser version with limited support for CSS. % Res. The only radiographically certain way of determining pulp exposure is the visualization of secondary caries and periapical changes in the alveolar process, such as widened periodontal ligament space or lack of continuity of lamina dura. Furthermore, prospective studies are required to evaluate the diagnostic accuracy of deep learning models against clinicians in a clinical setting. In cases of diseased third molar, where pain or pathology are obvious, there is a general consensus that surgical removal is indicated3. Amirsys. The most commonly used radiographic method for detecting caries lesions is the bitewing technique. Sci Rep 11, 12609 (2021).
