The aim of this study was to determine the correlation between laser fluorescence (LF) values of apparently sound tooth enamel and caries history. LF measurements were recorded from six sound enamel tooth surfaces in each of 346 subjects aged 8-25 years. Caries experience was evaluated using the decayed, missing, and filled tooth (DMFT) index and the International Caries Detection and Assessment System (ICDAS). To measure differences between the unrestored and restored tooth groups, an unpaired two-sample t-test was used. To assess the relationship between LF of sound enamel and caries experience based on the DMFT and ICDAS, Pearson's correlation coefficient and linear regression analyses were used. The LF values of sound dental enamel in subjects with no history of invasive dental treatment were highly correlated with caries experience, as measured by the DMFT index (R = 0.76) and ICDAS (R = 0.7). The LF values of sound enamel in subjects with a history of previous invasive dental treatment were weakly correlated with caries experience, as measured by the DMFT index (R = 0.33), and moderately correlated with the ICDAS values (R = 0.66). The LF value of clinically healthy tooth enamel correlates with caries status based on the DMFT or ICDAS.
本研究的目的是确定外观完好的牙釉质的激光荧光（LF）值与龋病史之间的相关性。对346名8至25岁受试者的每颗牙齿的六个完好牙釉质表面进行LF测量记录。使用龋失补牙（DMFT）指数和国际龋病检测与评估系统（ICDAS）评估龋病经历。为测量未修复牙齿组和修复牙齿组之间的差异，采用了不成对双样本t检验。为基于DMFT和ICDAS评估完好牙釉质的LF与龋病经历之间的关系，采用了Pearson相关系数和线性回归分析。无侵入性牙科治疗史受试者的完好牙釉质的LF值与龋病经历高度相关，DMFT指数测量结果显示相关系数R = 0.76，ICDAS测量结果显示相关系数R = 0.7。有侵入性牙科治疗史受试者的完好牙釉质的LF值与龋病经历弱相关，DMFT指数测量结果显示相关系数R = 0.33，与ICDAS值中度相关（R = 0.66）。基于DMFT或ICDAS，临床健康牙釉质的LF值与龋病状态相关。
