摘要
目的:比较定量光激发荧光(quantitative light-induced fluorescence,QLF)系统与数码照相、肉眼检查3种方法对上颌前牙早期脱矿病损的检出率。方法:对德阳市和资阳市300名12周岁中学生的1732颗上颌前牙清洁干燥后,肉眼检查是否存在上颌前牙早期脱矿病损,并拍摄QLF照片和数码照片进行分析。结果:经卡方检验得出,QLF系统对上颌前牙早期脱矿病损的检出率(24.08%)显著高于肉眼直接检查(20.61%)和数码照相(22.17%),其差异均有统计学意义(P<0.05)。结论:QLF系统是一种对早期脱矿病损较可靠、快速、安全、无损伤的诊断方法,值得推广使用。
PURPOSE： This study is to investigate the differences of primary caries detection on smooth surface in the maxillary anterior teeth using quantitative light-induced fluorescence （QLF）,digital photo and visual examination. METHODS： Three hundreds of middle school students in Deyang city and Ziyang city were examined. Seventeen hundreds and thirty-two maxillary incisors and canines were included. After being cleaned and dried, the white spots （primary caries on smooth surface） were examined by QLF, digital camera, and visual examination. The difference among three methods was analyzed by Chi-square test using SPSS 11.5. RESULTS： In QLF examination, 24.08 percent of the examined teeth were found out having white spots. Results of the Chi-square test showed that QLF had a significantly higher capability （24.08%） on finding out the primary demineralized spots than digital camera （22.17%） and visual examination（20.61%）. There was significant difference among the three diagnostic methods （P〈0.05）. CONCLUSION： The study suggested that QLF is a trustworthy, speedy, safe and noninvasive diagnosed method and was worthy extending and applying in the clinic.
