Table 1 summarizes the classification performance of MobileNet V2 on the test set, including the accuracy, positive predictive value, sensitivity, specificity and negative predictive value. Caries classification on third molars using PR(s) is flawed by limited and varying accuracy of individual examiners leading to inconsistent decisions and consequently suboptimal care9. The data used in this study can be made available if needed within the regulation boundaries for data protection. Caries activity is defined as active or inactive/arrested. Dental caries is a continuum of demineralization and remineralization with a net demineralization resulting in tooth surface alterations that eventually result in cavitation. endobj Sci Rep. 2022 Apr 12;12(1):6139. doi: 10.1038/s41598-022-10126-x. The prevalence of carious lesions in third molars is reported to range between 2.5% and 86%4. Sensitive caries detectors serve as adjuncts for early caries detection that help to shift the dental practitioner toward minimal intervention dentistry. Of the following statements which is more true? Thank you for visiting nature.com. Diagnostic accuracy of cone beam computed tomography compared with panoramic radiography. Clinical skills include detection and removal of calculus, accurate periodontal pocket depth measurements, tissue management, and final case presentation. Periapical means surrounding the apex of the root of a tooth ( Fig.1 ); hence it captures the complete crown and root of a tooth with about 2mm beyond the root apex. Occasionally, radiological abnormalities detected on an PR may even require further investigation with a cone-beam computed tomography (CBCT)5. Proc. Most of periapical radiolucencies are the result of inflammation such as pulpal disease due to infection or trauma. https://doi.org/10.1016/j.joms.2004.11.009 (2005).

There are multiple theories for their pathogenesis but contributing factors include a combination of a sugar-rich diet, anatomy, oral cavity microbiome, poor dental hygiene, hyposalivation and time 1,2. Subsequently, features are projected back to low-dimensional representation with a linear convolution18. Analog films are still being used in clinical practice; however, it is recommended that no dental radiographic film with speeds lower than E- or F-speed shall be used for intraoral radiography, as the dose is essentially halved from the older D-speed to E-plus or F-speeds. The ADEX Dental Hygiene Examination is based on specific performance criteria used to measure clinical competence. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Your email address will not be published. Studies have shown that the median time for caries penetrating the enamel to form is 6.1 months. Corresponding values for conventional radiography were 63% and 93% at the buccal line angle, 61% and 93% at the lingual line angle, and 44% and 95% at the mid-gingival floor, respectively.
