Resumo: The aim of this study was to evaluate the accuracy on the diagnosis of secondary caries-like lesions simulated on esthetic restorations of different materials, changing the incidence vertical angle (IVA) of the x-ray beam. Twenty human teeth received MOD inlay preparations. In the experimental group (n=10), a round cavity was made in the floor of the proximal box to simulate the caries-like lesion. All teeth were restored with 3 composite resins (Charisma, Filtek-Z250 and TPH-Spectrum) at 3 moments. Two radiographic images were acquired with 0º and 10º IVA. Ten observers evaluated the images using a 5-point confidence scale. Intra- and interobserver reliability was analyzed with the Interclass Correlation Coefficient and the diagnostic accuracy was evaluated using the area under the ROC curve (Az), Friedman test and Wilcoxon test (α=0.05). Higher accuracy values were obtained with 10º IVA (Az=0.66, Filtek-Z250>Az=0.56, TPH-Spectrum) compared to 0º (Az=0.55, Charisma>Az=0.37, TPH-Spectrum), though without statistically significant difference (p>0.05). The detection of secondary caries-like lesions simulated on esthetic restorations of different materials suffered no negative influence by changing the IVA of the x-ray beam.

Vinte dentes humanos foram submetidos a preparo cavitário inlay MOD. No grupo experimental (n=10), no soalho da caixa de proximal, foi confeccionada uma cavidade esférica para simular lesões iguais-a-cárie. Todos os dentes foram restaurados com 3 resinas compostas (Charisma, Filtek-Z250, TPH-Spectrum), em três tempos diferentes. Duas imagens radiográficas foram adquiridas com 0 e 10 graus de AVI o feixe de raios-x. Dez observadores avaliaram as imagens usando uma escala de confiança de 5-pontos. A reprodutibilidade intra- e inter- observador foi analisada com o coeficiente de correlação interclasse e a precisão do diagnóstico foi avaliada usando a área sob a curva ROC (Az), o teste de Friedman e de Wilcoxon (α=0,05). Os mais altos valores de precisão (p>0,05) foram observados com o AVI em 10º (Filtek-Z250 Az=0,66>TPH-Spectrum Az=0,56) comparado com 0º (Charisma Az=0,55>TPH-Spectrum Az=0,37), porém, sem diferenças estatisticamente significantes (p>0,05). A detecção de lesões iguais-à-cárie secundárias simulada em restaurações estéticas de diferentes materiais não foi influenciada pela mudança de AVI do feixe de raios-x.Fundação Odontológica de Ribeirão Preto (FUNORP)2020-10-04T02:12:16Z2020-10-04T02:12:16Z2011info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMOREIRA, P.
