Efficacy of the Sonicare Elite® in plaque removal and reduction of gingival inflammation fromhard-to-reach sites of the moderate periodontitis

The purpose of this study was to evaluate the efficacy of the Sonicare power toothbrush in plaque removal and reduction of gingivitis from hard-to-reach sites of the moderate periodontitis compared to regular manual toothbrush in 12 week follow-up. 82 subjects with incipient to moderate periodontitis were randomly assigned to use either the manual or sonic brush, instructed in its use, and asked to brush 2 times a day for 2 minutes. Plaque scores were taken at baseline, 1, 4, 12 weeks using Silness & plaque index and gingival inflammation was assessed by the & Silness gingival index. The results were as follows. 1. The Sonicare power toothbrush showed a significant reduction(p<0.0001) of the plaque(Silness & ) and gingival inflammation(Loe & Silness). 2. The Sonicare power toothbrush showed a significant better reduction of plaque and gingivitis(p<0.05) than the manual toothbrush after 1, 4, and 12 weeks. 3. The Sonicare power toothbrush demonstrated a significant reduction(p<0.0001) of the plaque in interproximal sites(p<0.0001), buccal sites(p<0.0001) and the lingual sites(p=0.00l8) of the teeth. 4. The Sonicare power toothbrush demonstrated a significant reduction(p<0.0001) of the gingival inflammation in the interproximal sites(p<0.0001), the buccal sites(p<0.0001) and the lingual sites(p
