How effective are powered and manual toothbrushes in everyday use, by people of any age, in relation to the removal of plaque, the health of the gingivae, cost, reliability and side effects?
The clinical importance of these findings remains unclear. The longer term result was based only on 14 trials, compared with 40 trials for the short-term analysis.
Good oral hygiene through the removal of plaque by effective toothbrushing has an important role in the prevention of gum disease and tooth decay. Dental plaque is the primary cause of gingivitis and is implicated in the progression to periodontitis. The build-up of plaque can also lead to tooth decay. Both gum disease and tooth decay are the primary reasons for tooth loss.
