The aim of this randomized controlled trial was to evaluate the interproximal cleaning efficacy of waist-shaped compared with straight soft interdental brushes in patients undergoing nonsurgical periodontal therapy.
Ten patients diagnosed with periodontitis stage II or III were scheduled for nonsurgical periodontal therapy. Baseline plaque control record (PCR), modified approximal plaque index (API), papillary bleeding index (PBI), probing pocket depth (PPD), and bleeding on probing (BOP) were evaluated. Four interdental spaces of equal sizes were determined, and baseline plaque indices (PI) were assessed on eight surfaces of the respective adjacent teeth, resulting in 640 measuring positions. Interdental brushes with a straight or waist-shaped design were randomly allocated to the right or left side, and patients received oral hygiene instructions. Follow-up measurements including PCR, API, PBI, and site-specific PI were performed during initial nonsurgical periodontal therapy sessions and reevaluation which was undertaken 8 weeks afterwards.
PCR, API, and PBI decreased significantly compared with baseline at each time point (p < 0.001). PPD (waist-shaped, baseline 4 mm (range, 2-9 mm) vs. reevaluation 3 mm (range, 1-6 mm); p < 0.001; straight, baseline 4 mm (range, 2-10) vs. reevaluation 3 mm (range, 1-6) mm; p < 0.001) and BOP (p = 0.008) showed significant reduction in both groups. Sub-analysis of site-specific areas including line angles and interproximal areas revealed no significant reduction of plaque during the observation period between both brush designs. No difference between straight and waist-shaped brushes regarding PPD or BOP decrease was found.
The efficacy of both interdental brush designs concerning plaque control in patients undergoing nonsurgical periodontal therapy was similar.
The use of interdental brushes is essential for biofilm removal in patients during initial periodontal therapy, regardless of brush design.

本随机对照试验旨在评估在接受非手术牙周治疗的患者中，与直型相比，腰形软邻间刷在邻间清洁方面的效果。
10 名诊断为牙周炎 II 期或 III 期的患者被安排接受非手术牙周治疗。基线菌斑控制记录（PCR）、改良近中菌斑指数（API）、乳头出血指数（PBI）、探诊袋深（PPD）和探诊出血（BOP）均进行评估。确定四个大小相等的邻间间隙，分别评估各自相邻牙齿的 8 个表面的基线菌斑指数（PI），共 640 个测量点。直型或腰形设计的邻间刷随机分配至右侧或左侧，患者接受口腔卫生指导。在初始非手术牙周治疗期间和 8 周后进行随访测量，包括 PCR、API、PBI 和特定部位的 PI。
与基线相比，PCR、API 和 PBI 在每个时间点均显著降低（p<0.001）。PPD（腰形，基线 4 毫米（范围 2-9 毫米）与再评估 3 毫米（范围 1-6 毫米）；p<0.001；直形，基线 4 毫米（范围 2-10 毫米）与再评估 3 毫米（范围 1-6 毫米）；p<0.001）和 BOP（p=0.008）均有显著降低。在两个刷型的特定部位（线角和邻间部位）的亚分析中，在观察期间未发现菌斑有显著减少。直型和腰形刷在 PPD 或 BOP 减少方面无差异。
在接受非手术牙周治疗的患者中，两种邻间刷设计在控制菌斑方面的效果相似。
在初始牙周治疗期间，无论刷型如何，使用邻间刷对于去除生物膜都非常重要。
