Laser fluorescence (LF)-based clinical device DIAGNOdent™ is at present being used to detect caries. Can the same be used to detect therapeutic remineralisation of early white spot lesions?
To explore the feasibility of using LF-based device in monitoring the changes following remineralisation of demineralised primary teeth.
The sample number for the present experimental in vitro study was 10. The LF based device readings were correlated with surface microhardness (SMH) test values to evaluate its efficiency. SMH analysis was performed using a microhardness tester (Tescol-HT1000AD). All the samples were demineralised, followed by remineralisation using fluoride varnish and pH cycling. The data was analysed using the Statistical Package for the Social Sciences (SPSS) version 17.0 (IBM SPSS®) software. Paired t-test was performed to compare laser fluorescence readings and SMH test result values at baseline, after demineralisation, and after remineralisation. Pearson's correlation was used to compare the relation between the laser fluorescence and SMH test.
A good negative correlation was seen between the two methods at the baseline readings even though it was not statistically significant (P = 0.069). A positive correlation between the methods existed following demineralisation which was not significant (P = 0.074). The correlation between the parameters following remineralisation showed a moderate negative correlation but was not significant (P = 0.55).
DIAGNOdent™ values at baseline, after demineralisation, and after remineralisation was consistent with SMH values. Thus, DIAGNOdent™ can be explored to provide chairside assistance in identifying remineralisation of white spot lesions.
基于激光荧光（LF）的临床设备DIAGNOdent™目前用于检测龋齿。它能否用于检测早期白斑病变的治疗性再矿化？
探讨使用基于LF的设备监测脱矿乳牙再矿化后变化的可行性。
本体外实验研究的样本数量为10。将基于LF的设备读数与表面显微硬度（SMH）测试值相关联，以评估其效率。使用显微硬度测试仪（Tescol-HT1000AD）进行SMH分析。所有样本均进行脱矿，然后使用氟化物清漆和pH循环进行再矿化。使用社会科学统计软件包（SPSS）17.0版（IBM SPSS®）软件对数据进行分析。进行配对t检验，以比较基线、脱矿后和再矿化后的激光荧光读数和SMH测试结果值。使用Pearson相关性分析来比较激光荧光和SMH测试之间的关系。
两种方法在基线读数时呈现出良好的负相关性，尽管在统计学上不显著（P = 0.069）。脱矿后两种方法之间存在正相关性，但不显著（P = 0.074）。再矿化后参数之间的相关性显示出中等程度的负相关性，但不显著（P = 0.55）。
基线、脱矿后和再矿化后的DIAGNOdent™值与SMH值一致。因此，可以探索使用DIAGNOdent™在椅旁协助识别白斑病变的再矿化情况。
