title: Ten-year retrospective observations of the impact of a rotary-powered brush vs manual techniques in periodontal maintenance.
abstract: The purpose of this retrospective study is to determine whether the type of home brushing instrument used by periodontal patients can affect recare compliance and tooth retention. Data from 201 cohorts, half of which used a rotary mechanical brush, were evaluated throughout 10 years. At recall, 25% of the manual and 67% of the rotary users exhibited good to very good oral hygiene, the rotary group lost 0.082 teeth/patient/year compared with 0.185 teeth/patient/year, and 92% of the rotary group maintained acceptable recare intervals compared with 51% of the manual group. The findings for the efficacy of the rotary brush for these 3 parameters are both statistically and clinically relevant.
