title: Comparison between the counter-rotational toothbrush and multi-action toothbrush.
abstract: Previous studies have demonstrated that two types of powered toothbrushes (Interplak and Braun) are more effective than a manual toothbrush in the removal of bacterial plaque from tooth surfaces. The purpose of this study was to compare the effectiveness of the Interplak Home Plaque Removal Instrument (A) and the Braun Electric Toothbrush (B) on supragingival plaque removal and gingival bleeding following (1) one time instruction; (2) reinstruction and one week of home use; (3) a third instruction and three weeks of home use. The sample population for this study consisted of twelve subjects: six (6) were randomly assigned to use the Interplak, and the remaining six (6) were assigned to use the Braun. Subjects met specific qualification criteria to participate in this examiner-blind study. The Turesky Modification of the Quigley-Hein Plaque Index and an Objective-Subjective Gingival Abrasion Index were scored before and after brushing at the initial appointment, one week later, and at the final appointment in three weeks. A timed bleeding index (Barnett-Muhleman) and probing depths were recorded at the beginning of all three appointments. Subjects received instructions on the use of the assigned toothbrush in a clinical demonstration and in a printed format to take home. Subjects were then supervised in their brushing technique. Data was analyzed using a Wilcoxon Signed Rank Test and Analysis of Variance with Repeated Measures where appropriate. Although the number of patients was small, a statistically significant difference (p less than .05) in plaque scores between the groups was obtained in favor of the Interplak.(ABSTRACT TRUNCATED AT 250 WORDS)
