title: Short-term clinical study comparing supragingival plaque removal and gingival bleeding reduction of the Philips Jordan HP735 to a manual toothbrush in periodontal patients in a maintenance program.
abstract: The Philips Jordan HP735 was compared to a manual brush for plaque removal efficacy and reduction of gingival bleeding. Subjects in a periodontal maintenance program were randomly divided into two groups; Group I (n = 27), average age 36.9 years, brushed with the manual brush; and Group II (n = 22), average age 32.9 years, brushed with the Philips Jordan HP735 electric brush. A dichotomous plaque and bleeding index was used at six sites on all teeth at baseline, three, six and nine weeks. The subjects did not use any other cleaning devices during the study. No significant statistical difference in plaque score or bleeding score was found between the two groups at baseline. Plaque scores did not statistically significantly decrease over time in either group, and there was no significant difference in plaque removal between groups during the study. The bleeding index decreased significantly in the electric toothbrushing group; however, due to the large variation in bleeding scores between subjects, the difference in the number of bleeding sites was not statistically significant between the two groups. In conclusion, in a group of periodontal patients in a maintenance phase, using an electric toothbrush did not significantly enhance plaque removal, but did decrease bleeding compared to baseline. The difference in bleeding percentages was not statistically significant compared to a manual brush.
