New Guide for Screening and Training of Assessors and a General Approach for the Sensory Evaluation of Toothbrushes

1. Scope

1.1 This guide provides guidelines for the selection and training of expert assessors for the sensory evaluation of toothbrushes. Sensory evaluation of toothbrushes can be used to define the sensory attributes of toothbrushes and then to measure these attributes quantitatively for the purposes of new product development, product optimization, competitive benchmarking, and claims substantiation. 1.2 A general framework for toothbrush descriptive analysis is provided to guide the reader in the design and execution (including sample preparation and presentation, facility and testing environment, and specific evaluation protocol) of toothbrush descriptive analysis evaluations. For the purposes of this Guide, standard manual toothbrushes (including those with additional features (e.g., tongue scrapers), standard battery powered toothbrushes, standard rechargeable toothbrushes, and single use manual toothbrushes are considered. 1.4 This guide provides suggested protocols and approaches to the evaluation of toothbrushes and in no way excludes any alternate approaches that may be effective in providing such perceptual evaluations. 1.5 This guide does not address other oral care products including, but not limited to, whitening agents, oral rinses, mouthwashes, toothpastes, dental flosses, denture adhesives, floss picks, or other oral care products. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
