Effect of application of dental varnishes on the properties and chemical composition in irradiated teeth.
Aims: To analyze the protective properties of fluor dental varnishes in teeth subjected to radiotherapy.
Methods and results: Eighty teeth were irradiated with a single dose of 60 Gy. Samples were randomized, and the following groups were made: negative control (n = 16); irradiation control (n = 16); irradiation + Duraphat (n = 16); irradiation + Mi Varnish (n = 16); and irradiation + Rivastar (n = 16). Energy dispersive x-ray (EDX) analysis and Raman spectrometry were performed to analyze the elemental composition and enamel's chemical structure. The Mi Varnish group presented a lower value (p < .05) in the Ca/F ratio than the other groups. Duraphat group presents differences (p < .05) in the ratio 1070 cm1-960 cm-1 compared to all the other groups.
Conclusion: Based on these in vitro results, the different varnishes used showed a similar preventive effect on the lesions produced by radiotherapy, with none standing out over the others.
