Objective: To compare the efficiencies of removing dental plaque and tongue plaque by toothbrushes that has omnidirectional bristles, the experiment was implemented with manual toothbrush type and sonic vibration toothbrush type.
Methods: Sixty children who had agreed to participate in the clinical study were divided into the experimental group and the control group for 30 each. For each experimental and control group, the sonic vibration toothbrush that has omnidirectional bristles and the manual toothbrush that has omnidirectional were provided and the instruction for proper tooth brushing were given as well. Both a simplified patient hygiene performance (S-PHP) index and a tongue plaque index were checked for both the groups prior to the experiment and 1 week and 2 weeks after. The repeated measure ANOVA analysis was performed to check the difference between two groups.
Results: Both the S-PHP index and the tongue plaque index decreased for experimental group compared to the control group, which showed a significant difference statistically at 1 week and 2 weeks after the clinical experiment (p<0.05).
Conclusion: Based on the results of the clinical trials, the sonic vibration toothbrush was statistically more efficient than the manual toothbrush in the removal of tongue plaque as well as in the perspective of oral hygiene management.
