- Scientific TitleThe effect of manual toothbrushing on dental plaque in healthy subjects: using a pre- rinse and regarding brushing order -RCT-
- hypothesis- Primary Objective exp. 1: What is the effect of manual toothbrushing after pre-rinsing for 1 minute with water compared with toothbrushing without pre-rinsing on the level of post-brushing dental plaque in healthy subjects?

- Primary Objective exp. 2: What is the effect of manual toothbrushing starting from the lingual aspect of the lower jaw compared with toothbrushing starting from the buccal aspect of the upper jaw on the level of post-brushing dental plaque in healthy subjects?

- Secondary Objectives: What is the opinion of the participants of the 48-hours non brushing protocol, the used toothbrush, the use of a dry/wet toothbrush and rinsing 1 minute of water?

- Additional post-trial objective: What is the difference between the plaque and gingivitis scores assessed orally and from an intra-oral photo taken with the SOPROCARE?

- Brief summaryThe clinical concepts established in the 1950s remain valid. Namely, that the maintenance of an effective plaque control is the cornerstone of any attempt to prevent and control periodontal diseases (Weijden van der & Hioe 2005). Toothbrushing is today the most widespread mechanical means of controlling plaque at home (Lang & Karring 1994). The efficacy of brushing with regard to plaque removal is dictated by three main factors: the design of the brush, the skill of the individual using the brush and the frequency and duration of use (Frandsen 1985). Toothbrushing techniques and procedures are thoroughly investigated to reach high quality of mechanical plaque-control, based on individual needs, which can efficiently prevent initiation (primary prevention) as well as recurrence (secondary prevention) of gingivitis and periodontitis. Supragingival plaque is exposed to saliva and to the natural self-cleansing mechanisms existing in the oral cavity. However, although such mechanisms may eliminate food debris, they do not adequately remove dental plaque (Weijden van der & Hioe 2005). Dawes et al. (1963) described plaque as the soft tenacious material found on tooth surfaces which is not readily removed by rinsing with water. However the high-speed camera videos as presented in Kronberg, Germany showed that pre-wetted plaque might be easier to remove. Mandibular lingual surfaces demonstrate greater accumulations of both hard and soft deposits and more bleeding on probing than other areas of the mouth. Despite these findings, standard toothbrushing focuses little or no attention on this area. Suggested by Axelsson (Lang & Karring 1994) the toothbrush should first be applied to the lingual of the mandibular posterior teeth, on the right side, where most right-handed people do not use the toothbrush efficiently. Lingual plaque reaccumulates rapidly in this region, and is most adhesive: toothbrushing should commence there, while most toothpaste is on the brush and the bristles are most rigid. The mandibular buccal and occlusal surfaces should then be cleaned (Lang & Karring 1994). Dentists and hygienists have dealt with this problem by simply telling patients to brush the inside of the bottom teeth first (O’Hehir 1998).
