Children’s dental health significantly improved using electric toothbrushes


An oscillating-rotating (OR) electric toothbrush is significantly more effective than a manual toothbrush at reducing plaque and gingivitis in young children (ages 3-10 years), according to new research conducted by Hebrew University Hadassah School of Dentistry.1

Tooth decay and gingivitis are often common problems in young children, affecting up to 74% of children between 9 months and 6 years old. The likelihood of first developing tooth decay increases with age, with more than 50% of five-year-olds reporting cavities. Studies have also shown that the prevalence of gingivitis in children is as high as 91%.

Professor Avi Zini, DMD, dean of the Hadassah School of Dentistry at Hebrew University, said: “Children love using electric toothbrushes, but most studies only look at whether electric toothbrushes or manual toothbrushes are better at reducing plaque that causes cavities and cavities. As long as children use their electric toothbrush according to the manufacturer's instructions, the results should be very beneficial to their oral health.

For the study, researchers followed two groups of children for four weeks: three- to six-year-olds whose parents brushed their baby teeth, and seven- to 10-year-olds who brushed their own baby and permanent teeth. Each group used an Oral-B Kids OR electric toothbrush or a Paro Junior manual toothbrush.

While brushing with any kind of toothbrush can reduce plaque and gingivitis, children do significantly better with an electric toothbrush.

After four weeks of trial:

  • More than half of children aged 3-6 years (55.7%) had a greater reduction in plaque throughout the mouth, with an even greater reduction in the back of the mouth at 34.3%

  • The vast majority of children aged 7-10 (94.5%) had a greater reduction in plaque in the entire mouth, and a greater reduction in plaque in the back of the mouth, reaching 108.4%.

  • In children aged 7-10 years, whole-mouth gingivitis was reduced by 14%, and retro-oral gingivitis was reduced by 18.8%.
