ABSTRACT
The aim of this ex vivo study was to compare visual clinical and radiographic examinations to the histological analysis for proximal caries diagnosis in extracted permanent molars and premolars. The relationship between clinical aspects and carious lesions was also evaluated. Eighty-eight proximal surfaces (44 freshly extracted teeth) were longitudinally sectioned with a 370-µm diamond disk, thinned with wet silicon carbide paper and observed with a stereomicroscope at x40 magnification. Sensitivity and specificity were 65.6 percent and 83.3 percent for clinical examination and 29.7 percent and 95.8 percent for radiographic examination, respectively. Kappa values ranged from 0.64 to 0.91. The white spots corresponded to lesions restricted to enamel, while the dark spots corresponded to lesions that reached the dentinoenamel junction. In most cases, cavitation corresponded to dentin lesions. It may be concluded that interproximal radiographic examination is not a reliable method for detection of incipient proximal carious lesions.
RESUMO
Este estudo ex vivo comparou os exames visual e radiográfico com a análise histológica no diagnóstico de cárie interproximal em pré-molares e molares permanentes extraídos. Também foi avaliada a relação entre os aspectos clínicos e as lesões de cárie. Para tanto, 88 superfícies proximais (de 44 dentes recém-extraídos) foram seccionadas longitudinalmente com um disco diamantado de 370 µm, polidas com lixas abrasivas e observadas em estereomicroscópio com aumento de x40. A sensibilidade e especificidade dos exames clínico e radiográfico foram 65,6 por cento e 83,3 por cento, e 29,7 por cento e 95,8 por cento, respectivamente. O índice de Kappa variou de 0,64 a 0,91. As manchas brancas corresponderam a danos em esmalte, enquanto as manchas escuras corresponderam à profundidade da junção amelo-dentinária. As cavitações clínicas corresponderam a lesões em dentina, na maioria dos casos. Conclui-se que o exame radiográfico interproximal não é um método confiável para descoberta clínica de lesões de cáries proximais incipientes.
