Exploring the Effectiveness of the Intentionality the Matrix of Healing in Enhancing 
Oral Health Education Outcomes for Community-Dwelling Middle-Aged and Older 
Adults 
 
Abstract 
Healthy aging is becoming increasingly important. As individuals age, three major 
symptoms—sarcopenia, dysphagia, and frailty—may develop. Early detection of oral 
functional decline and the implementation of oral health practices are essential for 
improving the quality of life in older adults. However, few studies have focused on 
the sustainability of self-care behaviors following oral health education among 
community-dwelling middle-aged and elderly individuals. Therefore, this study aims 
to apply the intentionality the matrix of healing framework as an intervention in 
community-based oral health education for middle-aged and elderly individuals to 
evaluate its effectiveness. A parallel randomized experimental design will be adopted, 
recruiting 90 middle-aged and elderly individuals from community through online 
channels. Participants will be randomly assigned to one of three groups: (1) 
Intentional interview combined with expressive arts activities, (2) Expressive arts 
activities only, or (3) Control group. Data on sarcopenia risk, eating assessment, grit, 
oral health literacy, and oral self-care behaviors were collected through questionnaires 
at baseline, one week after the intervention, and at a one-month follow-up. Statistical 
analyses, including descriptive statistics and inferential tests, were performed. The 
findings of this study are expected to provide evidence-based insights into the risks of 
sarcopenia and oral functional decline among community-dwelling older adults, while 
also offering empirical support for enhancing grit, oral health literacy, and oral self-
care behaviors. Ultimately, the results will contribute to advancing education, nursing 
practices, and policy development to improve the quality of life for middle-aged and 
elderly individuals in the community.
