Objective To compare the cleansing efficacy of waist‐shaped versus cylindric inter‐dental brushes in patients receiving supportive periodontal therapy. Materials and methods After sample size estimation, 20 periodontal maintenance patients diagnosed with periodontitis stage 3 were recruited. Brushing efficacy of waist‐shaped and cylindric inter‐dental brushes was evaluated in a randomized‐controlled, examiner‐blinded, two‐period crossover study by assessment of the Turesky modification of Quigley‐Hein plaque index (T‐QHI) and the papillary bleeding index (PBI) at four sites per tooth. Results Seventeen probands with 1,474 tooth sites finished the study. At baseline, median of overall T‐QHI scores was 1.4 (interquartile range 1.38–1.92). After 1 month, T‐QHI for waist‐shaped inter‐dental brushes was 1.24 (1.03–1.52); in 15 individuals, T‐QHI 0 was the grade most often measured. T‐QHI for cylindric brushes was 1.71 (1.18–2.29; p = .042), with T‐QHI 0 being the grade most often measured only in seven individuals. The odds ratio for establishing plaque‐free inter‐dental sites with waist‐shaped relative to cylindric brushes was 1.8 [95% CI 1.6–1.9] ( p < .001; logistic regression analysis). There were no statistically significant differences between PBI levels of waist‐shaped and cylindric brushes. Conclusion This study has demonstrated the superiority in cleansing efficacy of waist‐shaped over cylindric inter‐dental brushes in individuals receiving supportive periodontal treatment.
