Ultra-soft bristles are recommended for individuals with gingival recession, dentinal hypersensitivity, and patients who have undergone periodontal surgeries. However, comparative effectiveness of ultra-soft toothbrushes on dental plaque and bleeding indices has not extensively been studied, and a consensus has yet to be reached on their efficacy.
The aim of this study was to investigate the effect of ultra-soft toothbrushes with different commercial brands on plaque and bleeding indices.
In this crossover randomized clinical trial, 30 participants were selected using convenience sampling method. The subjects were randomly divided into three groups (n=10). In the first session, the bleeding index was recorded. Then each subject was given a toothbrush (Oral B, GUM, or Fuchs), asked to brush at least twice a day using the Bass technique, then avoid brushing for 24 hours after a week and refer for recording the indices. During the second session, bleeding on probing was recorded before brushing, and plaque indices were recorded before and after brushing. Plaque indices before brushing were considered the baseline plaque indices. After one week of washout, each subject used the next toothbrush in terms of the group involved. Turesky plaque index, O'Leary plaque index, and bleeding index were evaluated. The distribution of data was normal. Therefore, ANOVA, t-test, and post hoc tests were used for the analysis of data.
The bleeding and plaque indices decreased significantly compared to the baseline with the use of all the three ultra-soft toothbrushes evaluated (< 0.05), with no significant differences between the three brands (> 0.05) except for the superiority of Fuchs toothbrush in decreasing the Turesky plaque index.
Ultra-soft toothbrushes can reduce plaque index compared to the baseline, but they do not decrease the plaque index up to the optimal level, which might affect their prescription.
对于牙龈退缩、牙本质过敏的个体以及接受过牙周手术的患者,推荐使用超软刷毛牙刷。然而,超软牙刷对牙菌斑和出血指数的相对有效性尚未得到广泛研究,其功效也尚未达成共识。
本研究旨在调查不同商业品牌的超软牙刷对牙菌斑和出血指数的影响。
在这项交叉随机临床试验中,采用便利抽样法选取了30名参与者。受试者被随机分为三组(n = 10)。在第一阶段,记录出血指数。然后给每位受试者一支牙刷(欧乐B、GUM或福仕),要求他们每天至少使用巴氏刷牙法刷牙两次,一周后24小时不刷牙,然后前来记录各项指数。在第二阶段,刷牙前记录探诊出血情况,刷牙前后记录牙菌斑指数。刷牙前的牙菌斑指数被视为基线牙菌斑指数。经过一周的洗脱期后,每位受试者按照分组使用下一支牙刷。评估了Turesky牙菌斑指数、O'Leary牙菌斑指数和出血指数。数据分布呈正态分布。因此,采用方差分析、t检验和事后检验进行数据分析。
与基线相比,使用所有三种评估的超软牙刷后,出血和牙菌斑指数均显著降低(<0.05),除福仕牙刷在降低Turesky牙菌斑指数方面具有优势外,三个品牌之间无显著差异(>0.05)。
与基线相比,超软牙刷可降低牙菌斑指数,但未将牙菌斑指数降至最佳水平,这可能会影响其处方使用。
