Initial caries lesion: Early lesions that demonstrate net mineral loss in enamel or exposed dentin that may only be visible when the tooth is dried by air or color change toward white. Imaging is an integral component of caries detection. Radiographically, dental caries appears as radiolucency leading to loss of normal homogeneity of the enamel, as the lesion extends further toward the dentino-enamel junction (DEJ), the DEJ line loses its continuity in the region. Radiopaque Refers to structures that are dense and resist the passage of x-rays. The objective of this study is to assess the classification accuracy of dental caries on panoramic radiographs using deep-learning algorithms.

A daily dilemma in dentistry and oral surgery is to determine whether a third molar should be removed or not. Importantly, an increase in the quantity of sugar consumed alone is not a predictor of increased caries, as many communities around the world have increased caries preventive strategies over the same time period as sugar consumption has increased. Moderate caries lesion: Moderate mineral loss with loss of tooth surface integrity/anatomy with deeper demineralization. Gudkina J, Amaechi BT, Abrams SH, Brinkmane A, Jelisejeva I. Eur J Dent. Rarely, cavitated dental caries undergoes spontaneous arrest. Dental caries. The classification accuracy and the area-under-the-curve (AUC) were calculated. 1). During the caries process, bacteria-produced acids cause hydroxylapatite to be released from the dental tissues, which is why carious lesions appear less radiopaque than intact enamel or dentin. Dentin is exposed. Patients may also experience pain on eating, bad breath (fetor oris) or taste disturbances.
