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 cm-960 cm 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.
目的
分析氟化物牙科用清漆对接受放射治疗牙齿的保护特性。
方法与结果
80颗牙齿接受单次60 Gy的照射。样本随机分组，分为以下几组：阴性对照组（n = 16）；照射对照组（n = 16）；照射+Duraphat组（n = 16）；照射+Mi Varnish组（n = 16）；照射+Rivastar组（n = 16）。进行能量色散X射线（EDX）分析和拉曼光谱分析以分析元素组成和牙釉质的化学结构。Mi Varnish组的Ca/F比值低于其他组（p < 0.05）。与所有其他组相比，Duraphat组在1070 cm-960 cm比值上存在差异（p < 0.05）。
结论
基于这些体外研究结果，所使用的不同清漆对放射治疗产生的病变显示出相似的预防效果，没有一种清漆比其他清漆更突出。
