Comparing the efficacy of a high pressure spray oral hygiene appliance and a sonic vibration toothbrush in reducing dental plaque / 대한구강보건학회지

OBJECTIVES: This study aims to compare home care dental devices for their dental plaque removal ability. METHODS: A single blinded randomized crossover clinical study design was used to measure plaque index (Turesky Modification Quigley-Hein Plaque Index). RESULTS: All 3 groups showed a statistically significant decrease in the plaque index after usage (P<0.001). In manual tooth-brushing group, the teeth on the right dental arch showed a greater decrease in the plaque index than on the left arch (P=0.041). All appliances showed greater plaque reduction in the upper right posterior teeth than in the lower right posterior teeth (P=0.009, 0.004, 0.007). CONCLUSIONS: The results of this study support development of more effective oral hygiene appliances and emphasis on oral hygienic education.
