ImageNet: A large-scale hierarchical image database. What are the two major types of dental examinations? The confidentiality created by the dentist, the record, & the patient is: Violation does not apply to dental assistants. Radiotherapy for head and neck cancers lead to decreased salivation especially if the salivary glands are in the direct path of radiation. It is known that the short-term loss of function in the salivary glands leads to clinical xerostomia, which further accentuates clinical caries, especially rapidly advancing root caries. The disease develops in the crowns and roots of teeth, and it can arise in early childhood as an aggressive tooth decay that affects the primary teeth of infants and toddlers. Scheinfeld MH, Shifteh K, Avery LL, Dym H, Dym RJ. Enamel, Dentin, Cementum and bone: Enamel: is the most radiopaque structure. 634 . Imaging is an integral component of caries detection. The lack of lubrication and buffering action from saliva, increased salivary pH (acidic), and increased colonization of acidogenic bacteria (especially S mutans ) all lead to caries of smooth surfaces, and this is termed radiation caries, although it not directly caused by radiation. How many continuing education hours are required each year for a registered dental assistant? Rarely, cavitated dental caries undergoes spontaneous arrest. Incidence of occlusal dental caries in asymptomatic third molars. Being able to detect dental caries on radiographs is an essential skill needed for providing comprehensive dental treatment.
