    Caries Preventive Action of Nd:YAG and Fluoride in Three Different pH Conditions: FTIR Spectroscopy and SEM Evaluation

    by Amanda Caramel-Juvino, Nathalia A. Zanini, Sabrina Gardiano Avelino, Yasmin Reis Fontes-Oliveira, Gleice Conceição Mendonça Germano, Carlos de Paula Eduardo, Denise Maria Zezell

    This in vitro study aimed to evaluate the preventive action of topical fluoride application combined with laser irradiation under different pH conditions using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). A total of 180 samples of human dental enamel were prepared and divided into groups: Negative Control, Fluoride (FFA 12.300 µF−/g), Laser (Nd:YAG 84.9 J/cm2), and Laser + Fluoride (Nd:YAG 84.9 J/cm2 + FFA 12.300 µF−/g). The pH cycling was performed at three different pH conditions: pH 5 (below the critical pH for hydroxyapatite), pH 4.5 (below the critical pH in the presence of fluorapatite), and pH 4 (investigating acid resistance of hydroxyapatite and fluorapatite forms with laser irradiation). In the FTIR analysis, the Laser + Fluoride group demonstrated statistically significant differences compared to the Negative Control group and Fluoride group at pH 4.5 and pH 4 when evaluating the phosphate bands. Similar results were observed in the SEM analysis, where the Laser + Fluoride group exhibited lower demineralization compared to the other treatments at pH 4.5 and pH 4. In conclusion, the Laser + Fluoride group demonstrated a significant reduction in demineralization even at pH levels below the critical threshold for fluorapatite, highlighting its superior acid resistance compared to fluoride alone.

  • Evaluation of the anti-caries effect beyond the critical enamel pH of preventive treatment of fluoride associated with Nd: YAG laser irradiation

    by Amanda Caramel Juvino, Mariana Romano, Nathalia Zanini Alves, Thais Rabelo Freitas, Claudia Bianchi Zamataro, Denise Maria Zezell

    This study aimed to evaluate the anti-caries effect of fluoride associated with Nd:YAG laser irradiation in the treatment of enamel Eight groups (n = 5) were analyzed: Negative Control pH 4.5; Negative control pH 4; Fluoride pH 4.5; Fluoride pH 4; Nd-YAG pH 4.5; Nd-YAG pH 4; (Fluoride + Nd-YAG) pH 4.5 and (Fluoride + Nd-YAG) pH 4. AU samples were analyzed by Scanning Electron Microscopy (SEM) before and after the cycle. Quantification of phosphorus in the cycling solutions was carried out using the colorimetric method, as an indication of enamel demineralization. The anti-caries effect of the Fluoride + Nd:YAG treatment in addition to the critical pH of the enamel can be observed in the morphological analysis, however in the analysis of the demineralization solutions, the amount of phosphorus showed a difference only in the Fluoride group compared to the others in the investigative pH.
