The popularity of dental composites has grown over the years as a restoration material for dentists. Due to the dimensional shrinkage during polymerization and limited curing depth, restorations must be made in small layers, costing additional time in the process. Relatively new are flowable bulk fill composites that allow curing up to 4 mm, making it a much quicker option for making a restoration. These materials are indicated for class 1 and 2 restorations but must be topped occlusally with a regular posterior composite, due to inferior wear resistance. In the interproximal space however, these flowable bulk fill composites are exposed to the oral environment. Interdental brushes are advised to patients for interproximal cleaning, but the abrasive effect of these brushes is relatively unknown. In this study samples were made of Clearfil AP-X™ (AP-X) (n=120), SureFil SDR™ (SDR) (n=120), Venus Bulk FIll™ (VBF) (n=120) and Ketac Molar™ (GIC) (n=60). These samples were place 5 mm apart from each other and 1 year of interdental cleaning was simulated by moving cilindrical (Lactona 10 mm) or conical (Lactona 6-11 mm) interdental brushes in between the samples for 730 times. The thickness of every sample was measured before and after in mm. In all groups significant abrasive wear was observed. SDR showed significantly more wear than AP-X, GIC and VBF. VBF showed significantly more wear than AP-X. Using a cilindrically or conically shaped interdental brush showed no significant difference in terms of abrasive wear. Within the limits of this experiment, class 2 restorations are due to show more abrasive wear by one year of interproximal cleaning with interdental brushes than APX or GIC restorations. Use of cilindrically or conically shaped interdental brushes will make no difference in abrasive wear after one year of use.
