Recently, there has been an increase in the number of dental practitioners with no experience of endodontic treatment using optical instruments, but who are beginning to introduce optical instruments to locate root canal orifices and treat root canals. Moreover, advances in digital technology have led to optical instruments that we could call “digital magnifiers”, which allow the practitioner to view an enlarged image of the oral cavity on a display. However, no reports examining the issue of how effective these optical instruments are in terms of locating root canal orifices have been published to date. This study examined methods for objective evaluation of the accuracy of orifice location using the naked eye, optical instruments, and dental microscopes. Specifically, the authors also developed root canal orifice models replicating molar pulp cavities and attempted to locate root canal orifices. When orifices were searched for with the naked eye, the sensitivity was 86.44 and the specificity was 70.27, which gave a mean accuracy of 78.36. With a digital magnifier, the sensitivity was 90.63, the specificity was 90.63, and the accuracy was 90.63. Using a dental microscope produced a sensitivity of 83.61, specificity of 62.86, and an accuracy of 73.23. In observer performance, disparities in server scores were largest for the dental microscope and lowest for the digital magnifier. The root canal orifice model that produced the best outcomes had a score of zero root canal orifices and a pulp chamber floor depth of 8 mm. The worst outcome was the root canal orifice model with two root canal orifices and a pulp chamber floor depth of 7 mm. The digital magnifier had the highest level of accuracy in locating root canal orifices, followed by the naked eye and then the dental microscope. There was significant disparity among interobserver scores when the dental microscope was used, and the accuracy of orifice searches varied depending on the number of orifices and the depth of the pulp chamber floor. The findings suggest that practitionersʼ diagnostic ability can be objectively evaluated based on the sensitivity, specificity and accuracy of the outcomes of the search for root canal orifices using a digital magnifier with root canal orifice models, and that this approach may be effective for educating practitioners in the operation of optical instruments for dental use.","subitem_description_type":"Other"}]},"item_10002_full_name_75":{"attribute_name":"著者別名","attribute_value_mlt":[{"affiliations":[{"affiliationNames":[{"affiliationName":"朝日大学歯学部口腔機能修復学講座歯科保存学分野","lang":"ja"}],"nameIdentifiers":[]}],"familyNames":[{"familyName":"瀧谷","familyNameLang":"ja"},{"familyName":"TAKITANI","familyNameLang":"en"}],"givenNames":[{"givenName":"佳晃","givenNameLang":"ja"},{"givenName":"YOSHIAKI","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4071","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000002270004","nameIdentifierScheme":"CiNii
