Comparing the effect of dry and wet brushing on dental plaque removal in children.

AIMS

This study was aimed to assess the efficacy of wet and dry brushing on cleaning outcome of tooth surfaces.

METHODS

Forty-three children aged 10-12 years were randomly selected and instructed for this brushing project. Each case served as self-control. Each patient was requested to brush through one of the wet/dry techniques for 1 week and other technique on the 2 week. Samples had a washout step using pumice prophylaxis prior to each brushing week. Tooth Cleanliness Index was used to measure the plaque removal level. Two uniform Oral-B toothbrushes were used one for each week through the Modified Stillman technique. Mann-Whitney test was employed along with the Wilcoxon signed-rank test to analyze the data.

RESULTS

The level of brushing efficacy was slightly higher in males with no statistically significant difference between sexes. Remaining plaque measured was higher in wet group with significant difference (7.3 ± 1.7 for dry brushing and 7.6 ± 2.6 for wet brushing) (P < 0.05).

CONCLUSIONS

Dry and wet brushing did not show a significant difference in their capacity to remove plaque indicating that dry brushing could be considered as an acceptable brushing technique.
