Purpose: A new laboratory method was developed to compare GUM Expanding floss, Reach Mint Waxed and Oral-B Glide Pro-Health Deep Clean for their ability to reduce artificial plaque.
Methods: The floss product to be evaluated was affixed to the testing device and placed around interproximal surfaces of plaque-covered posterior-shaped teeth extending to a 60° angle. The testing apparatus was set to move in a vertical direction to the tooth apex at two strokes per second with a 5 mm stroke for 15 seconds.
Purpose: This laboratory study compared a newly designed GUM oscillating-rotating power toothbrush with a unique head design that combines both standard nylon filament and extremely tapered filaments to the Oral-B oscillating-rotating-pulsating power toothbrush with the Precision Clean head and to the Oral-B Compact 35 Indicator manual toothbrush for their ability to reach and remove artificial plaque deposits from hard-to-reach interproximal and subgingival sites.
Methods: Interproximal access efficacy (IAE) was evaluated using an artificial plaque substrate placed around simulated teeth. Subgingival access efficacy (SAE) was determined by using simulated gingiva prepared with a 0.
Objective: The purpose of this research was to evaluate five toothbrushes in a laboratory assay that determines the ability of toothbrush bristles to penetrate and remove artificial plaque from interproximal sites. Interproximal access efficacy (IAE), using the laboratory method employed, has been predictive of clinical plaque removal.
Methods: The toothbrushes tested were four elmex Caries Protection (SOFT, SOFT Short Head, MEDIUM, and MEDIUM Short Head) and the American Dental Association's (ADA) standard.
Objective: This laboratory study compared a specially engineered sonic powered toothbrush with unique sensing and control technologies and having two different brush heads to a manual flat-trim toothbrush for their ability to remove plaque at interproximal sites.
Methods: Interproximal access efficacy (IAE) was measured as the maximum width of plaque removed from the artificial plaque substrate around the teeth. Six brushes of each product were tested four times for a total of 24 tests.
Objective: A new toothbrush, with elongated fine bristles and a vibrating bristle field, has been designed and developed. In this study, the new product was compared to two commercially available powered, oscillating-rotating toothbrushes for efficacy using a laboratory method that has been predictive of clinical plaque removal.
Methods: Interproximal access efficacy (IAE) is a measure of the ability of toothbrush bristles to access interproximal sites and remove simulated plaque from these areas.
