Resumo
O objetivo deste trabalho foi comparar in vitro a efetividade de três métodos de diagnóstico da lesão de cárie em 26sítios de interesse, dispostos na face palatina de 20 coroas de dentes caninos permanentes de humanos. Quatro examinadores receberam orientação teórico-prática para o diagnóstico, através de três métodos: inspeção visual; táctil (inspeção visual - sonda exploradora com ponta romba); e videoscópico (sistema AcuCam). Para a validação dos dados, os dentes foram seccionados paralelamente ao seu longo eixo por um disco de diamante e analisados histologicamente em um microscópio estereoscópico com aumento de 40X. Diagnósticos compatíveis com o exame histológico apresentaram percentual de acerto no método de inspeção visual de 40,4%, no exame táctil de 38,5% e no videoscópico de 41,3%, resultados que não demonstraram diferença estatisticamente significante. Concluiu-se, pelos resultados obtidos, que os três métodos apresentaram acuidade semelhante no diagnóstico da lesão de cárie; dentre os métodos estudados, o exame ao videoscópio foi o que mais se aproximou do histológico, seguido pelo visual; o mais distante foi o táctil. Constatou-se também uma elevada porcentagem de erro de diagnósticos (59,9%), o que conseqüentemente acarretaria uma conduta terapêutica inadequada
The objective of this study was to compare in vitro the effectiveness of three methods for diagnosing carious lesions in 26 sites on palatal surfaces of 20 crowns in human permanent cuspids. Four examiners were given theoretical-practical guidance for diagnosis, by means of three methods: visual inspection, tactile (visual inspection - explorer probe with blunt tip); and videoscope (AcuCam System). To validate data, the teeth were sectioned parallel to the long axis with a diamond disk and analyzed histologically in a stereoscopic microscope with X40 magnification. Diagnoses compatible with the histological examination showed a percentile of accuracy of 40.4% for the visual inspection method, of 38.5% for the tactile examination, and of 41.3% for the videoscopic exam, results that did not demonstrate a statistically significant difference. Results obtained led to the conclusion that the three methods presented similar precision in the diagnosis of carious lesions. of the methods studied, the videoscopic examination came closest to the histologic followed by the visual, and the furthest was the tactile; a high percentage of error in diagnosis (59.9%) was also verified that would consequently engender inadequate therapeutic conduct
