Raman spectroscopy was used to investigate how the effect of pre-treatment protocols, with combinations of hydrochloric acid (HCl), sodium hypochlorite (NaOCl) and hydrogen peroxide (H2O2), for molar-incisor hypo-mineralisation (MIH) altered the penetration depth of polymer infiltrants (ICON, DMG, Hamburg, Germany). Furthermore, the effect on the structure of the MIH portions of the teeth with treatment is examined using multivariate analysis of spectra. It was found that pre-treatment protocols improved penetration depths. The structure of the MIH portion post-treatment appeared much closer to that of normal enamel suggesting a diminution of protein in the MIH region with treatment.
采用拉曼光谱法研究了盐酸（HCl）、次氯酸钠（NaOCl）和过氧化氢（H2O2）联合预处理方案对磨牙-切牙低矿化（MIH）的影响如何改变聚合物浸润剂（ICON，德国汉堡DMG公司）的渗透深度。此外，通过光谱多变量分析研究了治疗对牙齿MIH部分结构的影响。结果发现，预处理方案改善了渗透深度。治疗后MIH部分的结构似乎更接近正常釉质，表明治疗后MIH区域的蛋白质减少。
