Resumo
The present study evaluated the protective effects that are induced by fluoride and Nd:YAG
laser irradiation to control dentine erosion. One hundred and twenty bovine dentine slabs were
eroded with citric acid twice a day for a total period of 15 days. At day 10, the samples were
randomly assigned into eight groups: C (Control); F (Fluoride); L1 (Nd:YAG laser, 1 W, 100 mJ,
79.5 J cm2); L2 (Nd:YAG laser, 0.7 W, 70 mJ, 55.7 J cm2); L3 (Nd:YAG laser, 0.5 W, 50 mJ,
39.7 J cm2); F + L1; F + L2; and, F + L3. Optical Coherence Tomography images were collected
from the surface of the samples in order to monitor the alterations that were induced by erosion
and the effectiveness of each treatment using the Optical Attenuation Coefficient (OAC). OAC values
that were calculated for samples from groups C, F, L1, L3, FL1, and FL3 indicated no protective
effects against the progression of erosive lesions. Samples from L2 and FL2 groups presented OAC
values, indicating that laser irradiation under this condition did not induce the formation of craters on
dentine tissue and promoted sufficient chemical and morphological changes to avoid the progression
of dentine erosion.
