摘要
研究目的这项长期临床研究的目的是评估与手动牙刷(MT)相比,新开发的电动牙刷(PT)对原有牙龈凹陷(GR)的大小和数量的影响:这是一项前瞻性、单盲、平行组、随机对照临床研究。参与者没有牙周炎,但至少有两颗牙齿(指数牙)的牙龈凹陷≥2 毫米,他们被随机分配到每天用 MT 或 PT 刷牙两次,MT 或 PT 采用线性磁驱动,使圆形刷头产生轻微的微振动和摆动旋转运动。主要结果参数为 36 个月内指标牙齿 GR 的平均变化:结果:92 位参与者中有 87 位完成了研究(MT/PT:n = 42/n = 45)。在为期 36 个月的评估中,MT 和 PT 患牙GR的平均变化(标准差)差异显著,前者为 0.17 (0.77),后者为 -0.10 (0.63) (p = 0.013)。此外,在研究期间,GR 改善≥1 毫米或保持稳定的部位数量在 MT 和 PT 之间没有差异,但恶化≥1 毫米的部位数量明显有利于 PT(MT 23(25.5%)对 PT 10(10.6%);p = 0.009)。二元逻辑回归发现,牙齿类型(前/磨牙 OR = 2.991 (1.096 [95% CI 1.002-8.933]; p = 0.050))和手动刷牙(OR = 3.341 (1.206 [95% CI 1291-8648]; p = 0.013))是指数牙衰退损伤的风险因素。各组在不良事件方面没有差异:结论:对于牙龈已经存在退缩,因此很有可能出现进一步退缩的人群,PT 似乎有利于 GR 的进一步发展。
Effect of a powered and a manual toothbrush in subjects susceptible to gingival recession: A 36-month randomized controlled clinical study.
Objective: The objective of this long-term clinical study was to evaluate the influence of a newly developed powered toothbrush (PT) on the size and number of pre-existing gingival recessions (GR) in comparison to a manual toothbrush (MT).
Methods: This was a prospective, single-blind, parallel-group, randomized controlled clinical study. Participants without periodontitis, but with at least two teeth (index teeth) showing GR ≥2 mm were randomized to brush either twice daily with a MT or with a PT with a linear magnetic drive causing the round brush head to produce gentle micro vibrations along with oscillating-rotating movements. Primary outcome parameter was the mean change of GR at the index teeth over 36 months.
Results: Totally 87 out of 92 participants completed the study (MT/PT: n = 42/n = 45). At the 36-month evaluation the mean (standard deviation) change of GR at index teeth differed significantly between MT 0.17 (0.77) and PT -0.10 (0.63) (p = 0.013). Furthermore, the amount of GR sites which improved ≥1 mm or remained stable during the study period did not differ between MT and PT, but the number of sites worsened ≥1 mm was significantly in favour for PT (MT 23 (25.5%) versus PT 10 (10.6%); p = 0.009). A binary logistic regression identified tooth type (OR = 2.991 for pre-/molar (1.096 [95% CI 1.002-8.933]; p = 0.050)) and manual brushing (OR = 3.341 (1.206 [95% CI 1291-8648]; p = 0.013)) as risk factors for recession impairment at the index teeth. There were no differences between groups for adverse events.
Conclusion: In a population with pre-existing gingival recessions and consequently a high risk of developing further recession the PT seems to be favourable with regard to further development of GR.
