Thirty premolars were used for specimen preparation. Group 1 (the control group) consisted of intact enamel samples, group 2: CPP-ACPF (Tooth Mousse Plus), group 3: bioenamel remineralising gel (Prevest DenPro). All specimens were subjected to demineralisation except the control group, followed by which remineralising agents were applied. A universal hardness tester was used to assess the surface microhardness of all samples. Results were analysed using one-way ANOVA test and comparison was analysed using Scheffe\'s post hoc least significant difference (LSD) test.
Both remineralising agents used in groups 2 and 3 have shown significant outcome in terms of improving the surface microhardness in comparison with the control group. Group 2 increased the enamel hardness by 8.34 where P = 0.023 whereas group 3 increased the hardness by 5.87, where P = 0.01.
Group 2 has a superior hardness value than group 3; however, no statistically significant results were obtained between both the groups.
30颗前磨牙用于标本制备。第1组(对照组)由完整的釉质样品组成,第2组:CPP-ACPF(牙齿慕斯加号),组3:生物釉质再矿化凝胶(PrevestDenPro)。除对照组外,所有标本均进行了脱矿质处理,然后应用再矿化剂。使用通用硬度计评估所有样品的表面显微硬度。使用单因素方差分析对结果进行分析,并使用Scheffe的事后最小显著性差异(LSD)检验对比较进行分析。
与对照组相比,组2和3中使用的两种再矿化剂在改善表面显微硬度方面均显示出显著结果。第2组牙釉质硬度增加8.34,其中P=0.023,而第3组硬度增加5.87,其中P=0.01。
第2组的硬度值优于第3组的硬度值。两组间无统计学意义的结果.
