This study aimed to compare the remineralizing efficacy of strontium-doped bioactive glass, BioMin, and NovaMin containing dentifrices on artificial white spot lesions (WSLs) after chlorhexidine (CHX) pretreatment using energy-dispersive X-ray analysis (EDAX).
Twenty-four samples of maxillary first premolars extracted for orthodontic purposes were selected. Artificial WSLs were produced by immersing the samples in a prepared demineralizing solution for 3 days. All the samples were pretreated with CHX and divided into four groups and six samples each. Group A treated with strontium-doped bioactive glass, Group B with BioMin, Group C with NovaMin, and Group D with artificial saliva as the control group for 14 days. pH-cycling model was used to simulate the oral cavity changes. EDAX was used to record the values at baseline, demineralization, and after remineralization.
Data were analyzed using one-way ANOVA (), followed by unpaired -test and Scheffe tests with Statistical Package for the Social Sciences version 16.
Strontium-doped bioactive glass exhibited a greater mineral regain compared to BioMin, NovaMin, and control groups.
Strontium-doped bioactive glass has enhanced mineral deposition on carious teeth and may provide an alternative clinical strategy for remineralizing early enamel lesions.
本研究旨在使用能量色散X射线分析(EDAX)比较经氯己定(CHX)预处理后,含锶生物活性玻璃、BioMin和NovaMin的牙膏对人工白斑病变(WSLs)的再矿化效果。
选取24颗因正畸目的拔除的上颌第一前磨牙样本。将样本浸泡在配制好的脱矿溶液中3天以产生人工WSLs。所有样本均用CHX预处理,然后分为四组,每组六个样本。A组用含锶生物活性玻璃处理,B组用BioMin处理,C组用NovaMin处理,D组用人工唾液作为对照组,处理14天。采用pH循环模型模拟口腔变化。使用EDAX记录基线、脱矿和再矿化后的数值。
使用社会科学统计软件包第16版进行单向方差分析(),随后进行非配对检验和谢费检验。
与BioMin、NovaMin和对照组相比,含锶生物活性玻璃显示出更高的矿物质恢复量。
含锶生物活性玻璃增强了龋牙上的矿物质沉积,可能为早期釉质病变的再矿化提供一种替代临床策略。
