Comparison of sonic and ionic toothbrush in reduction in plaque and gingivitis.J Indian Soc Periodontol 2011; 15(3):210-4JI
A paucity of conclusive research exists on the optimal design and mode of action of toothbrushes, leading to the introduction of new generation of toothbrushes. Sonic and ionic toothbrushes belong to this new generation of toothbrushes. The aim of the present study was to clinically assess and compare the efficacy of the sonic and ionic toothbrushes.
MATERIALS AND METHODS
A single blind study, using a split-mouth method, was conducted for 45 days on a total of 22 (11 males and 11 females) student volunteers, with age of 17 to 21 years. Plaque, gingival, and bleeding indices were recorded after every 15 days.
Both the toothbrushes showed significant reduction in all three parameters. However, the sonic toothbrush proved to be more effective than the ionic toothbrush on the percentage basis, the difference in parameters was statistically nonsignificant.
It may be concluded from the present study that though the sonic toothbrush was insignificantly superior to the ionic toothbrush, both the toothbrushes are clinically effective in removing plaque and improving the gingival conditions.
