dc.description.abstractThe influence of dentin permeability on transdentinal LED light propagation should be evaluated since this kind of phototherapy may further be clinically used to stimulate the metabolism of pulp cells, improving the healing of damaged pulps. This study evaluated the influence of the dentin permeability on the transdentinal LED light (630 nm) transmission. Forty-five 0.5-mm-thick dentin disks were prepared from the coronal dentin of extracted sound human molars. An initial measurement of transdentinal LED light transmission was carried out by illuminating the discs in the occlusal-to-pulpal direction onto a light power sensor to determine light attenuation. The discs were treated with EDTA for smear layer removal, subjected to analysis of hydraulic conductance, and a new measurement of transdentinal LED light transmission was taken. Spearman's correlation coefficient was used for analysis of data and showed a weak correlation between dentin permeability and light attenuation (coefficient = 0.19). This result indicates that higher or lower dentin permeability does not reflect the transdentinal propagation of LED light. Significantly greater transdentinal propagation of light was observed after treatment of dentin surface with EDTA (Wilcoxon test, p < 0.05). According to the experimental conditions of this in vitro study, it may be concluded that dentin permeability does not interfere in the transdentinal LED light transmission, and that smear layer removal facilitates this propagation.en
