A Single-Brushing Study to Compare Plaque Removal Efficacy of a Manual Toothbrush, an Electric Toothbrush and an Ultrasonic Toothbrush

Introduction Bacteria present in dental plaque are the main cause of caries, gum disease, and periodontal disease. Therefore, the prevention and treatment of these diseases necessarily require the removal of plaque [1]. In 1965 Löe et al. have demonstrated that there is a relationship between plaque accumulation and inflammation of gingival tissues. Löe in 1981 proved that rigorous oral hygiene at home combined with professional cleaning and/or the use of antimicrobial components can control the appearance of oral bacterial plaque. Thus, it can be concluded that a rigorous and regular oral hygiene is necessary to a good oral health.
