Patients at a dental clinic were asked to participate in a toothpaste study. Their brushing times were covertly recorded and they completed a questionnaire about brushing habits. When the actual brushing times for the 154 subjects were compared to their estimated brushing time a highly significant difference was found. Approximately 90% of the subjects… (More)
1. Programed text and slide-tape presentations required significantly less study time than the lecture method. 2. Students of varying academic ability required approximately the same amount of study time. 3. Familiarity with self-paced study methods did not significantly affect study time.
A laboratory testing method, which has previously been shown to correlate with in vivo plaque removal results, was used to test the interproximal access efficacy (IAE) of two powered toothbrushes (Sonicare Plus and Braun Oral-B Ultra), and a manual toothbrush. This method tests IAE by means of simulated interdental spaces covered with pressure-sensitive… (More)
Eighteen subjects participated in a stain removal study following two months of Peridex use. The subjects were randomly assigned to use either Rembrandt dentifrice or Crest dentifrice for two months. Indices for stain area and intensity were taken at baseline, two, four, and eight weeks. After eight weeks' use, the Rembrandt group had a 37.1% lower stain… (More)
Sixty-five subjects were assigned to use Crest or Rembrandt dentifrice with either a placebo or Peridex rinse for eight weeks. One group, using Peridex, started with Crest and switched to Rembrandt at week four of the study. There were no significant differences among the groups on gingivitis, plaque, or calculus by the conclusion of the study. On the stain… (More)
Laboratory methods have been developed to evaluate the ability of toothbrush bristles to remove artificial plaque deposits at interproximal sites (Interproximal Access Efficacy; IAE) and on distal tooth surfaces (Posterior Tooth Surface Cleaning; PTSC). In the testing performed for this study, six toothbrushes were evaluated. These were: elmex inter X… (More)
Interproximal access efficacy (IAE) has been evaluated in a laboratory method using pressure-sensitive paper placed around simulated anterior and posterior teeth, using horizontal or vertical brushing motions. The two toothbrushes evaluated in this study were the Oral-B Cross Action Medium 40 and the Dr. Best X-Activ Mittel. Twenty-four tests on each… (More)
