The aim of this study was to analyze the correlation between the dental plaque indices measured using quantitative light-induced fluorescence-digital (QLF-D) and conventional clinical indices that assess gingival status.
From among the patients who visited Ewha Womans University Mokdong Hospital, 33 adults in their 20s who had relatively even teeth were selected for full-mouth QLF-D imaging. The images were used to analyze the QLF-D score and the QLF-D ΔR score. As clinical indices, the gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD), and patient hygiene performance (PHP) index were measured. The correlations between the QLF-D score and QLF-D ΔR score and each clinical index were analyzed. Analyses were performed comparing the indices of maxillary and mandibular teeth, the teeth on right and left sides of the mouth, anterior and posterior teeth, and buccal and lingual surfaces of each tooth. Pearson's correlation analysis was conducted (p < 0.05).
The mean full-mouth QLF-D score was highly correlated with the GI, BOP, PPD, PHP index (p < 0.01). The mean full-mouth QLF-D score showed the highest correlation with GI (r = 0.749) and the lowest correlation with PPD (r = 0.683). The correlations between the QLF-D score were higher in the mandible than in the maxilla and in the anterior teeth than in the posterior teeth, while no significant differences were seen between the buccal and lingual surfaces of tooth.
This study concluded that the correlations between the plaque indices measured for each tooth surface area using QLF-D and the clinical indices assessed were significantly high, and it allowed objective determination of the gingival status. Therefore, the plaque index measured using QLF-D may be used as an alternative to supplement the shortcomings of conventional clinical indices for educating patients about plaque control and continued patient oral care.
本研究旨在分析使用定量光诱导荧光数字化（QLF-D）测量的牙菌斑指数与评估牙龈状况的传统临床指数之间的相关性。
从访问梨花女子大学木洞医院的患者中，选择了 33 名 20 多岁的成年人，他们的牙齿相对均匀，对其进行全口 QLF-D 成像。使用图像分析 QLF-D 评分和 QLF-D ΔR 评分。作为临床指标，测量了牙龈指数（GI）、探诊出血（BOP）、探诊牙周袋深度（PPD）和患者口腔卫生性能（PHP）指数。分析了 QLF-D 评分和 QLF-D ΔR 评分与每个临床指标之间的相关性。比较了上颌和下颌牙齿、口腔左右侧牙齿、前牙和后牙、每个牙齿颊舌面的指数。进行了 Pearson 相关性分析（p<0.05）。
全口 QLF-D 评分与 GI、BOP、PPD、PHP 指数高度相关（p<0.01）。全口 QLF-D 评分与 GI 的相关性最高（r=0.749），与 PPD 的相关性最低（r=0.683）。下颌的 QLF-D 评分相关性高于上颌，前牙的 QLF-D 评分相关性高于后牙，但牙颊舌面之间无显著差异。
本研究得出结论，使用 QLF-D 测量每个牙面的菌斑指数与评估的临床指数之间的相关性显著较高，可以客观地确定牙龈状况。因此，使用 QLF-D 测量的菌斑指数可以作为替代方法，补充传统临床指数的不足，用于教育患者关于菌斑控制和持续的患者口腔护理。
