Innovative Mouthwash in School-Aged Children With Fixed Orthodontic Appliances

2026年7月13日 更新者：Plovdiv Medical University

Laboratory and Clinical Evaluation of an Innovative Mouthwash in School-Aged Children With Fixed Orthodontic Appliances

Fixed metal orthodontic appliances create additional plaque-retentive areas around brackets, archwires and ligatures, making mechanical plaque control more difficult in children and adolescents. Increased plaque accumulation may contribute to gingival inflammation, bleeding, halitosis and early enamel changes. Therefore, adjunctive preventive agents, including mouthwashes, may be clinically useful as part of a comprehensive oral hygiene program during fixed orthodontic treatment.

The aim of the study is to evaluate the clinical effectiveness and tolerability of a test mouthwash in children and adolescents with fixed orthodontic appliances by monitoring plaque accumulation, gingival inflammation, gingival bleeding and halitosis.

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
Orthodontic Plaque Index (OPI)
大体时间：Baseline, day 7, day 21, and 3 months

The Orthodontic Plaque Index focuses on the areas around the bracket, which represents an additional plaque-retentive factor. The dentition is divided into sextants and plaque accumulation is scored from 0 to 4. The mesial, distal, incisal and cervical areas around each bracket are evaluated. The highest score among all sextants defines the oral hygiene level and identifies the need for preventive measures.

Registry field data

Code 0 No plaque accumulation is detected.

Code 1 Plaque accumulation is detected on one tooth surface around the bracket base.

Code 2 Plaque accumulation is detected on two tooth surfaces around the bracket base.

Code 3 Plaque accumulation is detected on three tooth surfaces around the bracket base; increased risk of caries and gingivitis is assumed.

Code 4 Plaque accumulation is detected on all tooth surfaces around the bracket base and/or gingival inflammation is present.
Baseline, day 7, day 21, and 3 months
Gingival Index (Loe & Silness)
大体时间：Baseline, day 7, day 21, and 3 months

The index evaluates color, contour and bleeding of the gingival tissues. A World Health Organization (WHO) 621 periodontal probe is used to examine the gingival sulcus, and bleeding is recorded within 10 seconds.

Code 0 Normal gingiva.

Code 1 Mild inflammation: slight color change and slight edema, without bleeding on probing.

Code 2 Moderate inflammation: redness, edema and glazing, with bleeding on probing.

Code 3 Severe inflammation: marked redness and edema, ulceration and tendency to spontaneous bleeding.
Baseline, day 7, day 21, and 3 months
Full Mouth Bleeding Score (FMBS)
大体时间：Baseline, day 7, day 21, and 3 months
FMBS assesses provoked bleeding from the gingival sulcus using a WHO 621 periodontal probe. Bleeding is recorded within 10 seconds and marked as present (+) or absent (-). The index is calculated as the percentage of gingival sites with provoked bleeding from all examined sites for each child.
Baseline, day 7, day 21, and 3 months
Full Mouth Plaque Score (FMPS)
大体时间：Baseline, day 7, day 21, and 3 months
Dental plaque accumulation was assessed using the Full Mouth Plaque Score. The presence of visible plaque was recorded on tooth surfaces, and the result was expressed as the percentage of plaque-positive sites. Lower percentages indicate improved plaque control.
Baseline, day 7, day 21, and 3 months

Halitosis was assessed by gas chromatography using OralChroma™. Volatile sulfur compounds were measured, including hydrogen sulfide, methyl mercaptan and dimethyl sulfide.
Baseline, day 7, day 21, and 3 months
