The digital radiography is a technique potentially more sensitive than the conventional radiography. The aim of this study is to evaluate in vitro the accuracy and reproducibility of the digital radiography for caries lesion detection. The detection of occlusal surface caries of deciduous molars by digital radiography will be compared to that obtained by other caries detection methods such as, visual inspection, conventional radiography and fluorescence (DIAGNodent). Eighty human deciduous molars from the - Banco de Dentes da Disciplina de Odontopediatria da FOUSP - exhibiting occlusal surface pigmentation or at least one site with suspicion of caries, with no restorations neither sealant. The teeth will be cleaned with prophylactic procedures and stored in saline solution. All the evaluations will be carried out by two individual examiners. Then, one week later, these examinations will be done again by the same examiners. The results of the digital radiographies, visual inspections and conventional radiographies will be classified following the criteria proposed by Ekstrand et al.7 (1997). The results obtained by the DIAGNOdent will be classified following the manufacturer’s instructions. The data will be statistically compared using the histological sections of the teeth as the gold standard. (AU)
