The objective of this study was to evaluate the remineralization effect of two different mineral containing agents on white/creamy and yellow/brown demarcated opacities in incisors in children with molar-incisor hypomineralization (MIH) by using laser fluoresence (LF).
Fifty-three children (n=401 lesions) with MIH were randomly divided into three groups: (1)calcium glycerophosphate (CaGP), (2)casein phosphopeptide amorphous calcium fluoride phosphate (CPP-ACFP) and, (3)control (1450 ppm fluoride toothpaste). Remineralization was evaluated by means of LF, at baseline, after one and threemonths. Anova Test for Repeated Measurements in intra-group comparisons in evaluating the effectiveness of remineralization agents. One-way Variance Analysis (ANOVA) and Tukey-Kramer Multiple Comparison test were used in the comparisons between groups and, Student Newman Keuls Multpile Comparison Test was used to determine the differences between the measurement averages in case of p<0.05.
There was a significant improvement in MIH-lesions over time in all groups (p<0.001), with no differences between groups. The highest percentage of change was observed in CPP-ACFP in lesions LF≤20 scores and the mean percentage of change LF>20 scores, the highest percentage changes in CaGP. There was no significant difference between the groups over the time for all the used outcome measures (p>0.05).
The additional use of both mineral containing agents in MIH-affected teeth improved these hypomineralized lesions with mineral deposition. Even if both agents could be used in the hypomineralized teeth with demarcated opacities, future studies are recommended the long-term effect of these mineral containing agents with longer observation and a larger sample size.
本研究旨在通过激光荧光(LF)评估两种不同含矿物质制剂对儿童低矿化磨牙-前磨牙(MIH)的白色/乳白色和黄色/棕色边界不透明的再矿化效果。
53 名 MIH 患儿(n=401 个病变)被随机分为三组:(1)甘油磷酸钙(CaGP);(2)酪蛋白磷酸肽无定形氟化钙磷(CPP-ACFP);(3)对照组(1450ppm 氟化物牙膏)。通过 LF 在基线、治疗后 1 个月和 3 个月评估再矿化效果。采用重复测量方差分析(ANOVA)对组内比较进行分析,评估再矿化剂的有效性。采用单因素方差分析(ANOVA)和 Tukey-Kramer 多重比较检验比较组间差异,采用 Student Newman Keuls 多重比较检验在 p<0.05 时确定测量平均值之间的差异。
所有组的 MIH 病变在时间上均有显著改善(p<0.001),组间无差异。LF≤20 分的病变中 CPP-ACFP 的变化百分比最高,LF>20 分的病变中 CaGP 的变化百分比最高。所有使用的结果测量指标在所有时间点上,组间均无显著差异(p>0.05)。
在 MIH 受累牙齿中额外使用这两种含矿物质制剂可改善这些低矿化病变的矿物质沉积。即使这两种制剂都可以用于有边界不透明的低矿化牙,但建议进行长期研究,观察时间更长、样本量更大,以评估这些含矿物质制剂的长期效果。
