Because this damage to the oral cavity is irreversible, prevention is ideal. The international standards for testing toothbrushes for safety and efficacy are International Organization for Standardization (ISO) 22254, ISO 20126, and ISO 20127. American National Standards (ANSI)/American Dental Association (ADA) 119 is an adoption of ISO 22254 and ISO 20126 for manual toothbrushes, and ANSI/ADA 120 is an adoption of ISO 20127 for powered toothbrushes. ISO 22254 contains a test method for the resistance of the tufted portion to deflection, from which toothbrush stiffness is calculated. Key variables of this test method, such as changing the vertical load (VL) applied to the tufted portion of the brush head during testing and changing the velocity of the brushing table of the toothbrush stiffness test machine, were examined.</p></div><div><h3>Methods</h3><p>Twenty-eight different manual (n = 5) and powered (n = 23) toothbrushes were tested with modification according to the resistance to deflection method in ANSI/ADA 119.

However, the design of meaningful tests to confirm such properties faces severe problems because of the complexity of the interaction of materials with the oral biofilm. Furthermore, owing to practical reasons, such tests need to be performed in vitro. In contrast, there is a need for predictive data that are comparable between different laboratories. Therefore, standardization of such tests has been advocated. The International Organization for Standardization (ISO) with its Technical Committee 106–Dentistry may be the relevant platform for this purpose. A standard (ISO 3990) is being developed for testing the antibacterial properties of dental restorative materials. This standard defines basic requirements for sample preparation, selection of bacterial strains, test methods and assessment, and reporting of results.
