Background: The elderly are more likely to have swallowing and chewing problems due to degenerative conditions.

Objective: This study aimed to test the effectiveness of a dental health promotion program that applied a self-efficacy theory of mouth exercises to increase the strength of the oral cavity of older persons.

Methods: A quasi-experimental research study using a two group pre-post test design was used. The samples were older people divided into two groups, with 31 people allocated to each of an experimental and control group. Demographic data were collected using an interview form - self-efficacy towards oral health care and gingival health were recorded. The strength of the oral cavity was also tested. Data were analyzed using descriptive statistics, independent sample t-test and Pearson Chi-square test.

Results: The results showed that after the program, the experimental group had better self-efficacy towards oral health care than those in the control group (p = .03). When comparing oral strength, there was no significant difference between the two groups. However, the experimental group had better gingival health than those in the control group (p < .01).

Conclusions: Although the strength of the oral cavity in both groups was not significantly different, oral health after the trial of the experimental group tended to be better. It is important to promote training on self-efficacy to enhance healthy gums and oral health of older persons.
