背景技术定期去除牙菌斑是良好口腔卫生和促进牙龈健康的关键。这项研究旨在比较使用牙菌斑指数(PI)使用软牙刷和中等牙刷的效果,牙龈指数(GI),和探查出血(BOP)指数。材料和方法采用随机平行组研究设计。64名参与者被随机分配到2个类似的干预组(中型和软牙刷组)。PI,GI,使用BOP指数。PI的中位数和中位数差异,GI,和BOP进行了计算。采用SPSS进行数据录入和分析。使用Wilcoxon和Mann-WhitneyU检验进行数据分析。结果GI中位数得分,PI,和BOP分别从1.8、1.7和2.0显著下降,在使用中型牙刷之前,分别为0.0、0.1和0.0,使用中型牙刷后(所有P<0.0001)。同样,GI的中位数,PI,和防喷器分别从2.0、1.7和2.0显著下降,在使用软牙刷分别达到1.1、0.9和1.0之前,使用软牙刷后(P<0.0001)。GI的中位数差异,PI,使用中型牙刷的人的BOP得分高于使用软牙刷的人的中位数差异[(1.8vs0.9),(1.6vs0.8),和(2.0vs1.0),分别]。这些差异具有统计学意义(P<0.0001)。结论本研究得出的结论是,中型和软式牙刷可有效去除牙菌斑和控制牙龈炎。在实现这些结果方面,中型牙刷比软牙刷更有效。
BACKGROUND Regularly removing dental plaque is key to good oral hygiene and gingival health promotion. This study aimed to compare the effects of using soft and medium toothbrushes using the plaque index (PI), gingival index (GI), and bleeding on probing (BOP) index. MATERIAL AND METHODS A randomized parallel-group study design was used. Sixty-four participants were randomly assigned to 2 similar intervention groups (medium and soft toothbrush groups). The PI, GI, and BOP indexes were used. The median and median difference of PI, GI, and BOP were calculated. SPSS was used for data entry and analysis. Wilcoxon and Mann-Whitney U tests were used for data analysis. RESULTS The median scores of GI, PI, and BOP significantly decreased from 1.8, 1.7, and 2.0, respectively, before using medium toothbrushes to 0.0, 0.1, and 0.0, respectively, after using medium toothbrushes (all P<0.0001). Similarly, the median scores of GI, PI, and BOP significantly decreased from 2.0, 1.7, and 2.0, respectively, before using soft toothbrushes to 1.1, 0.9, and 1.0, respectively, after using soft toothbrushes (P<0.0001). The median differences in GI, PI, and BOP scores among those using medium toothbrushes were higher than the median differences among those using soft toothbrushes [(1.8 vs 0.9), (1.6 vs 0.8), and (2.0 vs 1.0), respectively]. These differences were statistically significant (P<0.0001). CONCLUSIONS This study concludes that medium and soft toothbrushes were effective in removing plaque and controlling gingivitis. Medium toothbrushes were more effective than soft toothbrushes in achieving these outcomes.
