Abstract
Three diagnostic methods were used to detect occlusal caries: fiber-optic transillumination (FOTI), bitewing radiographs (XR), and clinical examination (CE). The premolars and first molars of 58 subjects (aged 12-37 years) were examined by three gauged examiners. Radiolucency in enamel and/or dentine for XR; shadow in enamel and/or dentine for FOTI were considered as cavity. The restored or radiographically unreadable surfaces were excluded. The results observed for occlusal surfaces were: XR without radio-lucency (w.r.) and CE sound (s) = 88,39%; not sound (n.s.) = 6,13%; XR with radiolucency and CE s. = 0% and n.s. = 5,48%; XR w.r., FOTI s. = 91,2% and n.s. = 0%; XR with radiolucency and FOTI s. = 1,17% and n.s. = 7,63%; FOTI s. and CE s. = 87,61% and n.s. = 5,6%; FOTI n.s. and CE s. = 0,86% and n.s. = 5,9%. A high degree of agreement among the methods assessed was observed in dentine, particularly between FOTI and XR, that presented the highest concordance. Although not able to diagnose lesions confined to enamel, FOTI and XR may be considered important complementary means for occlusal caries diagnosis.

Resumo
Três métodos de diagnóstico foram utilizados para detectar cárie oclusal: fibra óptica de transiluminação (FOTI), radiografia interproximal (rX) e exame clínico (EC). Os pré-molares e molares de 58 pacientes, com idades entre 12 e 37 anos, foram examinados por três examinadores calibrados. Radioluscência em esmalte e/ou dentina para o RX, sombra em esmalte e/ou dentina para o FOTI foram considerados como cavidade. As superfícies restauradas ou radiograficamente ilegíveis foram excluídas do estudo. Os resultados observados foram: rX sem imagem (s.i.) e EC saudável (s) = 88,39; c/cavidade (c.c.) = 6,13; rX c/imagem (c.i.) e EC s. = 0 e c.c. = 5,48; rX s.i., FOTI s. = 91,20 e c.c.= 0; rX c.i. e FOTI s. = 1,17 e c.c.= 7,63. FOTI s. e EC s. = 87,61 e c.c. = 5,60. FOTI c.c. e EC s. = 0,86 e c.c. = 5,90. Os dados foram analisados e permitiram as seguintes conclusões: um alto grau de concordância foi observado entre todos os testes; a radiografia interproximal e o FOTI são importantes meios complementares no diagnóstico de cáries oclusais.
