摘要

目的：分析氟化物清漆对接受放射治疗的牙齿的保护作用：对 80 颗牙齿进行单剂量 60 Gy 的照射。对样本进行随机分组：阴性对照组（n = 16）；辐照对照组（n = 16）；辐照 + Duraphat 组（n = 16）；辐照 + Mi Varnish 组（n = 16）；辐照 + Rivastar 组（n = 16）。能量色散 X 射线（EDX）分析和拉曼光谱分析用于分析元素组成和珐琅质的化学结构。与所有其他组别相比，Mi Varnish 组呈现出较低的值（p 1-960 cm-1）：根据这些体外实验结果，所使用的不同清漆对放疗引起的病变具有相似的预防效果，没有哪种清漆比其他清漆更突出。

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.
