JERUSALEM, Israel: Electric toothbrushes, particularly those with oscillating-rotating (O-R) movements, have shown superior plaque removal efficacy compared with manual brushes in adults and children. However, there is limited evidence on their long-term effectiveness in reducing gingivitis and plaque in preschool-aged children. A study by researchers at the Hebrew University–Hadassah School of Dental Medicine in Jerusalem has compared the efficacy of an O-R toothbrush with that of a manual toothbrush in children with primary and mixed dentition and made significant findings in favour of O-R toothbrushes.
