Resumo: | Objective: To verify the existence of hidden caries and compare the diagnosis agreement among different Examiners between the visual and radiographic exam and computed microtomography images of incipient dental lesions on the occlusal surface of extracted molars.Methods: Two hundred and fifteen healthy teeth were extracted from the corpses of children with a mean age of 12 years and analysed by visual examination. However, only 11 teeth were included in current study because they showed suggestive caries image when examined by microtomography (micro CT scan). Occlusal sites were examined both visually and by dental radiograph by 3 different dental practitioners and results were compared and validated independently by each Examiner with computed microtomography, henceforth a gold-standard in current investigation. The coefficient of agreement was calculated by Cohen’s kappa test.Results: the coefficient of agreement among Examiners for the diagnosis by standard microtomography was excellent (K = 0.924) and moderate for both the visual (K=0.515) and the radiographic (K=0.583) examinations. Computed microtomography-produced images allowed the Examiners to visualize radiolucent areas, unseen in previous radiographic images and visual exams, in which there existed communication between enamel and/or dentine and the external environment.Conclusion: Hidden caries was the product of the conventional exam´s limitations, or rather, the lesion was due to enamel non-collapse. Consequently, conventional exams were not accurate enough to detect the lesions. |

Entretanto, apenas 11 dentes foram incluídos no presente estudo pois apresentavam imagem sugestiva de cárie quando examinados em microtomografia (micro CT scan). Os sítios oclusais foram examinados tanto visualmente como radiograficamente por 3 cirurgiões dentistas e foram comparados e validados independentemente para cada examinador com microtomografia computadorizada, doravante um padrão ouro em pesquisa. O coeficiente de concordância foi calculados pelo teste de Cohen’s kappa.Resultados: O coeficiente de concordância entre examinadores para o diagnóstico pelo padrão da microtomografia foi excelente (K=0.924) e moderado para ambos exames visual (K=0.515) e radiográfico (K=0.583). As imagens produzidas por microtomografia permitiu aos examinadores visualizarem áreas radiolúcidas, não observadas em imagens radiográficas prévias e exame visual, no qual havia comunicação entre esmalte e/ou dentina e o ambiente externo.Conclusão: Cárie oculta foi o produto da limitação de exames convencionais, ou melhor, a lesão se dava no esmalte não colapsado. Consequentemente, exames convencionais não foram precisos o suficiente para detecção de lesões.EDIPUCRS - Editora Universitária da PUCRS2015-07-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/1459210.15448/1980-6523.2015.2.14592Revista Odonto Ciência; Vol. 30 No. 2 (2015); 45-50Revista Odonto Ciência; v. 30 n. 2 (2015); 45-501980-65230102-946010.15448/1980-6523.2015.2reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/14592/13616Copyright (c) 2015 Revista Odonto Ciência (Journal of Dental Science)info:eu-repo/semantics/openAccessSantos Junior, Valdeci Elias dosTargino, Andreza Cristina de LimaAlencar Filho, Arnoldo Vasconcelos deRosenblatt, Aronita2015-11-03T19:34:29Zoai:ojs.revistaseletronicas.pucrs.br:article/14592Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2015-11-03T19:34:29Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
