Summary

The aim of the present randomized and single-blinded cross-over study was to compare the cleansing efficacy of waist-shaped interdental brushes with that of cylindric interdental brushes in interproximal sites.

Detailed description

Brushing efficacy of cylindric and waist-shaped interdental brushes was evaluated in a randomized, controlled, examiner-blinded, two-period crossover study. 20 periodontal maintenance patients of the University Hospital of Dental Prosthetics and Restorative Dentistry were recruited. Each subject was asked to attend three appointments. In the first visit (day one), baseline plaque and bleeding indices were assessed. Each proband was instructed by the same experienced dental hygienist with two sizes of waist-shaped and cylindric interdental brushes, respectively. Primary outcome measure plaque index and secondary outcome measure papillary bleeding index were assessed by two blinded and calibrated examiners at four sites per tooth.The odds ratio and confidence interval for establishing plaque free interdental sites were calculated with logistic regression analysis.
