The purpose was to compare the effect of 0.2% sodium fluoride mouthwash and casein phosphopeptide-amorphous calcium phosphate paste on prevention of dentin erosion.
Buccal surfaces of 36 sound premolar teeth were ground flat and polished with abrasive discs. Half the polished surfaces were covered with tape to maintain a reference surface. Samples were randomly allocated into three groups. Group A was pretreated with tooth mousse (TM) 4 times a day for 5 days. Group B was pretreated with 0.2% sodium fluoride mouthwash 4 times a day for 5 days. Group C was considered as the control group with no pretreatment. In the next step, the samples were exposed to Coca-Cola 4 times a day for 3 days. After each erosive cycle, the samples were rinsed with deionized water and stored in artificial saliva. The surface loss was determined using profilometry.
The erosion in both Groups A and B was less than the control group. The surface loss in mouthwash group was significantly lower than in the control group. Erosion in TM group was more than the mouthwash group and less than the control group.
Sodium fluoride mouthwash is more effective for prevention of dentin erosion.
比较0.2%氟化钠漱口水和酪蛋白磷酸肽-无定形磷酸钙糊剂预防牙本质侵蚀的效果。
将36颗完好的前磨牙颊面磨平，用砂纸盘抛光。一半抛光面用胶带覆盖以保留参考面。样本随机分为三组。A组每天用护齿素（TM）预处理4次，共5天。B组每天用0.2%氟化钠漱口水预处理4次，共5天。C组作为未进行预处理的对照组。下一步，样本每天暴露于可口可乐4次，共3天。每个侵蚀周期后，样本用去离子水冲洗并储存在人工唾液中。使用轮廓仪测定表面损失。
A组和B组的侵蚀均小于对照组。漱口水组的表面损失显著低于对照组。护齿素组的侵蚀大于漱口水组且小于对照组。
氟化钠漱口水预防牙本质侵蚀更有效。
