简要总结
The primary aim of this clinical study is to compare the effects of IDBs and RBICs on the removal of microbial dental plaque and gingival bleeding in patients with gingivitis. Secondarily, the study aims to assess participants' satisfaction and attitudes toward using these tools.
详细描述
This study involved 40 systemically healthy, right-handed, non-smoking patients aged 18-35 with gingivitis and no prior experience with interdental cleaning tools. Inclusion criteria required a probing depth ≤3mm, a full-mouth bleeding on probing score ≥20%, at least 20 natural teeth, and a minimum of four evaluable interproximal sites per quadrant compatible with both test devices. Key exclusion criteria were severe gingivitis, attachment loss, systemic diseases, recent antibiotic use, and pregnancy.
Participants received standardized toothpaste, a toothbrush, and training in the modified Stillman brushing technique. Following a 2-week training phase on product use and a professional prophylaxis, they refrained from interdental cleaning for 3 days to allow plaque accumulation for baseline assessments (T-QHPI for plaque, PBI for gingival bleeding).
The study employed a split-mouth design. After baseline, one side of the mouth was assigned an interdental brush (IDB - TePe® Original, sizes 0.4-1.5mm) for daily use, and the contralateral side was assigned a rubber bristle interdental cleaner (RBIC - TePe EasyPick™, XS/S or M/L size). Participants were instructed on proper insertion and technique for each device.
After two weeks of use, clinical indices were re-recorded by a blinded examiner. Additionally, participants completed a questionnaire assessing their satisfaction with various aspects of the products (cleaning capacity, accessibility, ease of use, overall satisfaction, willingness to reuse, and pain experienced during use).

结局指标
主要结局
Plaque Levels
时间窗: 2 weeks
Plaque levels were assessed using the Turesky modification of the Quigley and Hein Plaque Index (T-QHPI). In each participant, dental plaque was disclosed using Mira-2-Ton® (Duisburg, Germany) and then rinsed with water (10 mL for 10 seconds). The stained plaque was scored on a scale from 0 to 5 as follows: 0 = no plaque; 1 = separate flecks of plaque at the cervical margin; 2 = a thin continuous band of plaque (up to 1 mm) at the cervical margin; 3 = plaque covering not more than one-third of the tooth surface; 4 = plaque covering more than one-third but not more than two-thirds of the tooth surface; 5 = plaque covering more than two-thirds of the tooth surface.
Gingival condition
时间窗: 2 weeks
Gingival condition was evaluated using the Papillary Bleeding Index (PBI) introduced by Saxer and Mühlemann. Measurements were performed by a blinded, calibrated examiner on four sites per tooth (mesiobuccal, distobuccal, mesiolingual, and distolingual). A manual UNC-15 mm periodontal probe (Hu-Friedy, Chicago, IL, USA) was carefully inserted into the gingival sulcus at the base of the papilla on the mesial side and moved coronally toward the tip of the papilla. The same procedure was repeated on the distal aspect. Bleeding severity was scored on a scale from 0 to 4: 0 = no bleeding; 1 = a single discreet bleeding point visible after 20 seconds; 2 = a fine line of blood or multiple bleeding points in the papilla; 3 = blood filling the entire interdental space; 4 = profuse bleeding that overflows from the interdental area
