The diagnosis of proximal carious lesions is a very difficult task, even with the radiographs. Wenzel and Hintze in 1999 found that radiography is far from being an accurate method for caries diagnosis, particularly for small proximal lesions. On the other hand, Moystad et al in a previous study in 1996 emphasized the need for the development of methods that can correctly discriminate sound surfaces from those with carious lesions, especially in the outer half of enamel. Consequently, because of the need of more accurate methods for proximal caries diagnosis, mainly with the aim of detecting early lesions, it is necessary to verify if the introduction of alternative systems provided a significant contribution to the radiographic caries diagnosis recent studies have focused on the dental application of 3D imaging modalities to avoid the overlap of 3D anatomic structures in 2D images (Haiter-Neto et al 2008).
