Comparative Clinical Study of Dental Plaque Removal Efficacity between Manual Brushing, Electric Brushing and Ultrasonic Brushing

The aim of this study was to see how successful a manual, powered, and ultrasonic toothbrush is at reducing dental plaque in a dental student population.

Materials and Procedures: This is a comparative cross-over analysis that enrolled 50 students and had them all complete it. All of the participants had to be in good general health and have a full dentition free of malocclusions. They had to refrain from brushing their teeth for 12 hours and from consuming any food or drink for 4 hours before each of the three appointments, during which the plaque index was measured before and after brushing with a toothbrush. Brushing time for the tooth assigned that day was 3 minutes for manual brushing and 2 minutes for electric and ultrasonic brushing.

After brushing, both toothbrushes substantially decreased plaque index (p106). The ultrasonic toothbrush was significantly more efficient at removing plaque than the manual toothbrush (P = 0.0003). The distinction between an electric toothbrush with oscillation-rotation action and a manual toothbrush (P = 0.0982), as well as the comparison between rotary and ultrasonic electric rotary toothbrushes (p = 0.0922), was statistically insignificant.

Conclusion: After brushing, the three toothbrushes were able to reduce the amount of plaque. In terms of plaque removal, the ultrasonic toothbrush outperforms the manual toothbrush.
