Introduction

Dental erosion has a great effect on oral health, when diagnosed it is irreversible, this sets the importance of different preventive measures being investigated against dental erosion.

Aim

This in vitro study aims to evaluate the effectiveness of silver diamine fluoride and Potassium iodide (SDF-KI) in comparison to casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF) varnish, sodium fluoride (NaF) varnish, silver diamine fluoride (SDF) alone and deionized water as a control group in the prevention of dental erosion in primary teeth and assessing its staining effect.

Materials and methods

Forty deciduous teeth enamel specimens were randomly allocated into the five study groups. Tested materials were applied. An erosive challenge was done by immersing the specimens in a citric acid-containing soft drink with pH 2.85, for 5 min, 4 times/day, for 5 days. Changes in surface microhardness, mineral loss, and color change were evaluated besides recording of the surface topography and surface roughness for selected specimens.

Results

The highest decrease in surface microhardness was recorded in the control group (−85.21 ± 10.60%), with a statistically significant difference (p = 0.002). SDF-KI group (−61.49 ± 21.08%) showed no statistically significant difference when compared to CPP-ACPF, NaF, and SDF groups. For calcium and phosphorous loss, control group was statistically significantly higher compared to the treatment groups (p = 0.003) and (p < 0.001) respectively, while there was no statistically significant difference between the tested treatment groups. The highest mean value for color change was recorded in SDF group (26.26 ± 10.31), followed by SDF-KI group (21.22 ± 12.87) with no statistically significant difference between groups.

Conclusions

SDF-KI is as effective as CPP-ACPF, NaF varnishes and SDF in the prevention of dental erosion in primary teeth, there was no statistically significant difference regarding its staining potential.

氟化二胺银/碘化钾治疗预防乳牙侵蚀的效果：体外研究

介绍

牙齿侵蚀对口腔健康有很大影响，一旦确诊，它是不可逆转的，这表明了研究不同预防措施来预防牙齿侵蚀的重要性。

目的

这项体外研究旨在评估氟化二胺银和碘化钾( SDF-KI) 与酪蛋白磷酸肽-无定形磷酸钙氟化钙 (CPP-ACPF) 清漆、氟化钠 (NaF) 清漆、氟化二胺银 (SDF) 的有效性）单独使用去离子水作为对照组，预防乳牙侵蚀并评估其染色效果。

材料和方法

四十颗乳牙釉质样本被随机分配到五个研究组。应用经过测试的材料。通过将样本浸入 pH 2.85 的柠檬酸软饮料中 5 分钟，每天 4 次，持续 5 天来进行侵蚀挑战。除了记录所选样品的表面形貌和表面粗糙度之外，还评估了表面显微硬度、矿物质损失和颜色变化的变化。

结果

对照组的表面显微硬度下降幅度最大（−85.21 ± 10.60%），具有统计学显着性差异（p = 0.002）。与CPP-ACPF、NaF和SDF组相比，SDF-KI组（−61.49 ± 21.08%）没有表现出统计学上的显着差异。对于钙和磷的损失，对照组分别比治疗组（p = 0.003）和（p < 0.001）统计显着更高，而测试治疗组之间没有统计学显着差异。SDF组的颜色变化平均值最高（26.26±10.31），其次是SDF-KI组（21.22±12.87），组间无统计学显着差异。
