Effectiveness of children's habitual toothbrushing.

Area of Science:

• Pediatric Dentistry
• Oral Hygiene Research
• Behavioral Science

Background:

• Individual toothbrushing habits are typically consistent across different aspects like frequency, pattern, and duration.
• Understanding the impact of these habitual behaviors is crucial for effective oral health education.

Purpose of the Study:

• To analyze the effect of habitual toothbrushing habits on plaque removal in 13-year-old schoolchildren.
• To determine which aspect of toothbrushing (frequency, pattern, or duration) most significantly influences plaque removal.

Main Methods:

• Clinical examination of plaque before and after habitual brushing in 110 schoolchildren (aged 13).
• Filming of toothbrushing to assess pattern by dentists and measure duration.
• Assessing plaque removal using computer planimetry of photographs and the WHO oral debris index.

Main Results:

• Toothbrushing duration demonstrated the strongest effect on plaque removal.
• Frequency of brushing impacted plaque removal only in boys' maxillary teeth.
• Brushing pattern affected plaque removal in girls generally, and in boys' left jaw quadrants.

Conclusions:

• The duration of toothbrushing is the most critical factor for effective plaque removal in children.
• Dental health education should prioritize emphasizing the importance of sufficient toothbrushing duration for improved oral hygiene.
