The aim of the study is to evaluate the effectiveness of different toothbrushes in reducing gingival inflammation and dental biofilm removal in gingivitis patients with fixed orthodontic appliances.
Following baseline clinical assessments, including the Turesky modification of the Quigley-Hein plaque index (TQHI), gingival index (GI), bleeding on probing (BOP), and probing pocket depth (PPD), all patients received nonsurgical periodontal therapy. Patients were then randomly assigned to one of three groups: conventional toothbrush (C-TB), orthodontic toothbrush (O-TB), or single-tufted toothbrush (ST-TB). Each group received tailored oral hygiene instructions based on their assigned toothbrush type. Clinical assessments were repeated and recorded in the first week, sixth week, and third month.
Thirty-six patients with a mean age of 23.14 ± 3.86 (18-32 years) participated in the study. All groups with twelve patients each demonstrated significant improvements in clinical parameters compared to baseline. In the sixth week, the O-TB and ST-TB groups showed significantly greater improvements in TQHI and BOP scores compared to the C-TB group (p < 0.05). By the third month, the ST-TB group maintained significantly lower TQHI and BOP scores, while the O-TB group's scores became similar to those of the C-TB group. ST-TB and C-TB groups had significantly lower GI scores than the O-TB group in all time points. Although the effectiveness of ST-TB was significantly higher than that of other toothbrushes, all toothbrushes demonstrated lower efficacy in the posterior region.
The ST-TB was shown to be more effective in reducing gingival inflammation over three months, while it demonstrated similar efficacy to the O-TB in dental biofilm removal. Further research is necessary to substantiate these findings and to demonstrate the efficacy of this approach in promoting periodontal tissue health in patients with fixed orthodontic appliances.

本研究旨在评估不同牙刷在减少固定正畸矫治器患者牙龈炎和牙菌斑方面的效果。
在基线临床评估后，包括 Turesky 改良的 Quigley-Hein 菌斑指数（TQHI）、牙龈指数（GI）、探诊出血（BOP）和探诊深度（PPD），所有患者均接受非手术牙周治疗。然后，患者被随机分配到三组：常规牙刷（C-TB）、正畸牙刷（O-TB）或单束牙刷（ST-TB）。每组根据分配的牙刷类型接受了定制的口腔卫生指导。在第一周、第六周和第三个月重复临床评估并记录。
36 名年龄在 23.14±3.86 岁（18-32 岁）的患者参与了这项研究。所有组，每组 12 名患者，与基线相比，临床参数均有显著改善。在第六周时，O-TB 和 ST-TB 组的 TQHI 和 BOP 评分改善明显优于 C-TB 组（p<0.05）。到第三个月时，ST-TB 组的 TQHI 和 BOP 评分保持显著较低，而 O-TB 组的评分变得与 C-TB 组相似。ST-TB 和 C-TB 组在所有时间点的 GI 评分均明显低于 O-TB 组。尽管 ST-TB 的效果明显高于其他牙刷，但所有牙刷在后牙区的效果均较低。
ST-TB 在三个月内更有效地减轻牙龈炎，而在去除牙菌斑方面与 O-TB 效果相似。需要进一步研究来证实这些发现，并证明这种方法在促进固定正畸矫治器患者牙周组织健康方面的有效性。
