Cleaning evaluation of toothbrushes, interdental brushes, flosses and tapes through in vitro laboratory studies and instrumental efficacy measurement
In vitro cleaning efficacy studies allow the evaluation of toothbrushes, interdental brushes, flosses and tapes which have been developed to remove stain or plaque from tooth surfaces and interproximal spaces.
New toothbrushes and interdental cleaning products are constantly being developed with novel materials, different filament types / profiles, or penetration enhancers. Toothbrushes, for example, have many innovative designs in terms of different bristles materials, arrays and shapes which drive marketing claims for these consumer products. Such products may have been developed to improve plaque reduction or stain removal from difficult to reach places. Independent evidence that clearly demonstrates performance is important to support marketing claims or packing claims and also to direct further development.
Laboratory Evaluations of Toothbrushes, Tapes and Flosses
Our team of laboratory scientists are able to carry out comparative testing for the cleaning evaluation of brushes, flosses and tapes. We are experienced in the design and fabrication of dental and interproximal cleaning models using extracted human teeth which can either be stained or coated with an artificial plaque. Following use of the product, cleaning efficacy is assessed using digital image analysis giving you a robust insight into cleaning efficacy.
Cleaning studies are appropriately powered to investigate significant improvements in efficacy and sufficient repeats are planned to assess product and assessor variability. Images can be assessed subjectively or by using digital analysis. Percentage cleaning data and any requested statistical analysis is provided in a report containing tables, graphs and images.
For over 19 years our Clinical Research Services has been a trusted partner for developers and manufacturers of oral care products. Our wider in vitro laboratory based oral care solutions include anti-plaque and anti-calculus oral care product testing, anti-stain, stain removal and tooth whitening testing, Pellicle Cleaning Ratio (PCR) laboratory studies or dentinal tubule blockage studies. Intertek's Total Quality Assurance expertise, brings quality and safety to life by providing a one-source solution for in vitro studies providing robust data to support the efficacy and marketing claims of novel treatments.
