title: Laboratory and clinical evaluations of the Jordan Exact toothbrush.
abstract: A new toothbrush, the Jordan Exact, has been compared with a flat multitufted toothbrush, the Oral-B 35 toothbrush. In a laboratory study the Jordan Exact toothbrush had significantly higher interproximal access, compared to the Oral-B 35, combining all toothbrushing pressures tested, using either vertical or horizontal brushing motions on simulated molar teeth. Clinical safety and efficacy were evaluated in a 30-day single blind study. Evaluations of plaque mean scores were recorded before and after a one minute brushing at baseline, day 15 and day 30. At the same time periods, assessments of irritation, gingivitis and bleeding on probing were conducted. No oral irritation from either toothbrush was observed or reported throughout the test period. At all examinations there were no significant differences in overnight plaque scores. After brushing, an analysis of covariance on plaque area scores revealed that the Jordan Exact toothbrush removed significantly more plaque than the Oral-B 35 toothbrush. By day 30, the Jordan Exact toothbrush significantly reduced gingivitis on buccal surfaces but no significant change was observed in the Oral-B 35 group. Subjects using the Jordan Exact toothbrush had a significant decline in bleeding on probing; subjects in the Oral-B 35 toothbrush group had no significant change over the 30 days of the study.
