ABSTRACT
Objective:
To evaluate the use of nanosilver fluoride in the enamel remineralization process through optical coherence tomography. Material andMethods:
All samples were submitted to demineralization process by pH cycling during 14 days and randomly distributed into three groups (n = 11) Nanosilver Fluoride (NSF), Sodium fluoride (NaF), and negative control. Optical coherence tomography images were acquired at three different moments initial stage (T0), post caries formation (T1), and post pH cycling (T2). The integrity of the enamel surface and the measurement of the volume loss for the tissue after pH cycling in comparison to initial images were obtained from optical coherence tomography images.Results:
After analyzing the exponential decay of A-scans from each group, it was possible to identify differences in light propagation among samples. In T1 it is not possible to visualize the dentin-enamel junction, probably due to the higher back scattering of the demineralized enamel, which does not allow light to reach the dentin. The decay curves obtained from NaF and nanosilver fluoride groups showed similar behavior, while the negative group showed lower extinction coefficient.Conclusion:
Nanosilver fluoride showed the best effect against caries compared to conventional fluoride treatments.Palavras-chave
