Cleaning efficacy of interdental brushes in different interdental space types
Jörß, Daniela/Wolff, Diana/Pioch, Thomas/Dörfer, Christof E.
Introduction: No information is available which factors influence the cleaning efficacy of interdental brushes.
Aim: To evaluate in vitro the cleaning efficacy of interdental brushes in different types of interdental spaces.
Methods: Interdental brushes with diameters of 2, 3, 4 and 5 mm (Curaden AG) were tested in 8 pairs of extracted human molars combined to simulate two types (isosceles and equilateral) of interdental spaces with 4 sizes each. After coating the teeth with a dye to simulate plaque, digital images were taken from the proximal surfaces in a highly standardized setup. The teeth were repositioned and the proximal surfaces were cleaned in a reproducible manner. Post-brushing images were taken as before. After digital subtraction, the cleaned area was measured by pixel count. Percentage of cleaned surface area was taken as cleaning efficacy.
Results: The cleaning efficacy was 10.1± 7.8% (2mm), 16.8± 9.6% (3mm), 23.0± 9.7 % (4mm) and 22.5± 7.8% (5mm) in equilateral interdental spaces. In isosceles the cleaning efficacy was 13.2± 5.1% (2mm), 20.0± 4.7% (3mm), 26.6± 7.7 % (4mm) and 25.9± 7.0% (5mm), respectively. The differences between the different types of interdental spaces were statistically significant (Wilcoxon test for paired samples, p
