摘要

牙齿漂白剂可能会削弱牙齿的结构，因此，尽量减少它们对牙釉质和牙本质的损害是很重要的。因此，不同的材料被用来避免或减少牙齿在漂白过程中的损伤。近年来，生物活性玻璃已被证明是有效的矿化牙齿结构。因此，本研究利用激光诱导击穿光谱(LIBS)技术评估了生物硅酸盐(一种多晶生物活性玻璃陶瓷)漂白后的效果。获得4 × 4 × 3 mm的牛牙块(n = 20)，依次包埋在环氧树脂中，然后抛光。使用35%过氧化氢(白度HP)进行漂白。在处理前(T0，基线-对照组)、漂白后(T1)和应用BioSilicate®后(T2)，通过libs4测定钙(Ca)和磷酸盐(P)强度值。漂白后使用生物硅酸盐®是牙釉质表面再矿化的最佳方法，使生物硅酸盐®应用成为避免或尽量减少漂白后牙釉质表面矿物损失的有希望的辅助步骤。

After bleaching enamel remineralization using a bioactive glass-ceramic (BioSilicate®)

Abstract Tooth bleaching agents may weaken the tooth structure, therefore, it is important to minimize any risks of enamel and dentine damage caused by them. In this way, different materials have been used to avoid or minimize the tooth damage during bleaching. Recently, bioactive glasses have been demonstrated to be effective in mineralization of dental structures. Therefore, this study evaluated the effect of BioSilicate® (a polycrystalline bioactive glass-ceramic) after bleaching by Laser-induced breakdown spectroscopy (LIBS) technique. Bovine dental blocks with 4 × 4 × 3 mm were obtained (n = 20), sequentially embedded in epoxy resin and then polished. Bleaching was performed using 35% hydrogen peroxide (Whiteness HP). Calcium (Ca) and phosphate (P) intensity values by LIBSwere obtained before the treatment (T0, baseline – control Group), after bleaching (T1), and after BioSilicate® application (T2). The use of BioSilicate® after bleaching showed to be an optimal way to remineralize enamel surface making BioSilicate® application a promising adjunct step to avoid or minimize the mineral loss on enamel surface after bleaching.
