Abstract

Proximal surface lesions are not very often detected by X-Ray examination, suggesting the predominance of a subjective diagnosis on the part of the dentist. Since the magnitude of light scattering within the tooth decreases exponentially at longer wavelengths[1], evaluation of transillumination by near infra red lasers is a new alternative non-invasive technique [2] to detect and quantify demineralization of lesions.
