Twenty participants enrolled in this 3-arm crossover intraoral ETW simulation and wore their own partial denture for 14 d holding 2 human enamel specimens (per arm). In each arm, participants were assigned to 1 of 3 different dental erosion protocols severe (lemon juice/pH 2.5), moderate (grapefruit juice/pH 3.5), and no erosion (bottled drinking water, control). Enamel specimens were evaluated by white-light scanning confocal profilometry for 3D surface texture and surface loss (ETW model validation). Individual point clouds were analyzed using standard dental microwear texture characterization protocols for surface roughness and anisotropy. Fractal complexity (Asfc), texture aspect ratio (Str), and arithmetical mean height (Sa) values were generated at baseline, 7 d, and 14 d. Data were analyzed by analysis of nitor the progression of severe lesions. No clear characterization of ETW lesions could be provided by the anisotropy (Str) parameter. The purpose of this study was to translate the Environmental Assessment Tool-Higher Care (EAT-HC) into Japanese and validate its use in small-scale group living facilities in Japan. Environment of a facility is shown to improve its residents' quality of life (QOL). Japan's "welfare-based nursing homes for the elderly" are gradually shifting to a small-scale group living concept called group care units (GCUs). However, there is no appropriate environmental tool available for evaluating GCUs. The application of valid environmental assessment tools brings about a better understanding of the nature of good environments and the relationship between environments and outcomes for residents living with dementia. The study had a mixed method design conducted in several steps, covering tr
