A study on emotionally engaging toothbrush design for children: An empirical approach based on child psychology and cognitive development.

This study investigates the emotional engagement of children aged 3-12 with toothbrush color design from a psychological perspective, focusing on three distinct age groups: 3-5 years, 6-8 years, and 9-12 years. While previous research has primarily concentrated on the physical attributes of toothbrushes, this study employs a mixed-methods approach that combines quantitative surveys with qualitative interviews and observations, to analyze children's emotional responses and preferences for various toothbrush designs across different age groups. The findings reveal significant age-related differences in emotional engagement; younger children tend to prefer bright colors and playful shapes, whereas older children prioritize functionality.

Study on the Association between anterior tooth Colour Preference based on the FAHP and individual factors.

Background: The relationship between tooth colour and individual satisfaction in oral aesthetics has long been a topic of interest. In this study, we utilized the fuzzy analytic hierarchy process (FAHP) to investigate the impacts of sex and age on tooth colour preference. The findings of this study should provide a scientific basis for oral aesthetic practice.

Research on product design of FAHP bone marrow aspiration needle.

Bone marrow aspiration is a crucial medical procedure to obtain bone marrow samples for diagnosis and treatment. However, traditional bone marrow aspiration needles face several challenges such as operational difficulties, inadequate sample acquisition, and patient discomfort. To address these issues, we aimed to design a bone marrow aspiration needle product by using fuzzy analytic hierarchical process (FAHP).
