METHODS: The study was conducted on young adults aged between 18 and 25 years. Digit ratio and reproductive hormones were measured; dental plaque score and gingival index (GI) were recorded. Data were analysed using the MedCalc. v.20.
RESULTS: Male and female participants were categorized into two groups based on their digit ratios being either above or below the calculated average (0.99 for females, 0.98 for males). Those with a digit ratio below the average had a significantly higher mean dental plaque score (p < 0.0001) than those with ratios at or above the average. However, there was no significant difference in the GI between the two groups. Reproductive hormone profiles varied significantly between the higher and lower digit ratio groups for both sexes.
CONCLUSIONS: Digit ratio may find potential to be used as an anatomical marker to identify the susceptibility to dental plaque build-up.
方法:这项研究是针对年龄在18至25岁之间的年轻人进行的。测量数字比率和生殖激素;记录牙菌斑评分和牙龈指数(GI)。数据使用MedCalc进行分析。v.20.
结果:根据数字比率高于或低于计算的平均值,将男性和女性参与者分为两组(女性为0.99,男性为0.98)。数字比率低于平均值的那些具有显著高于平均值的平均牙菌斑评分(p<0.0001)。然而,两组之间的GI没有显着差异。男女的高数字比率组和低数字比率组之间的生殖激素谱差异显着。
结论:数字比可能被用作解剖标记以确定牙菌斑积聚的敏感性。
