Resumo: The aim of this study was to evaluate two methods of optical density measurement in a group of second deciduous molars and to relate the presence of dentine caries in the occlusal surface with the values obtained with de optical density measurement by two different computer softwares. With this purpose, 28 standardized radiographs were digitized and evaluated by two different softwares, in order to obtain the optical density measurement. The results obtained with the software Digora® for Windows 2.1 were compared with the ones obtained with the software Image Tool for Windows 3.0. The numbers found with the optical density measurement were compared with the teeth sections exam on the stereomicroscope. There were no differences between the values of optical density measurement found in both softwares, Digora and Image Tool. The optical density measured in teeth without occlusal caries lesions in dentine were different from the one measured in those with occlusal caries lesions in dentine (p = 0.035). On the other hand, with the results obtained in this study, it was not possible to establish optical density values corresponding to occlusal surfaces with or without caries lesions in dentine. UNITERMS: dental caries; digital dental radiography; primary dentition

UNITERMS: dental caries; digital dental radiography; primary dentitionO objetivo deste estudo foi comparar o desempenho de dois sistemas de medição de densidade óptica numa amostra composta por segundos molares decíduos, assim como relacionar a presença de lesão de cárie dentinária na superfície oclusal de segundos molares decíduos com os valores de densidade óptica desta superfície, utilizando dois programas de computador. Para isso foi realizada a medição da densidade óptica de 28 radiografias padronizadas de segundos molares decíduos em dois programas de computador diferentes. Os resultados obtidos com o programa Digora® for Windows 2.1 foram comparados com os obtidos no programa Image Tool for Windows 3.0. Ainda, os valores de densidade óptica encontrados foram relacionados aos diagnósticos obtidos com o exame dos dentes no estereomicroscópio. Os programas Digora e Image Tool apresentaram valores de densidade óptica semelhantes, sem diferença estatisticamente significativa. Ainda, a densidade óptica observada nos dentes que não apresentavam lesões de cárie dentinárias na superfície oclusal foi diferente daquela cujos dentes possuiam lesão em dentina (p = 0,035). Entretanto, com os resultados obtidos neste estudo não foi possível estabelecer intervalos de densidade óptica correspondentes a superfícies oclusais com presença ou ausência de lesões de cárie em dentina.
