A brief Acceptance and Commitment Therapy (ACT) intervention did not significantly reduce gingivitis or plaque in young adults. However, ACT showed a positive effect on oral health in females, suggesting a potential gender-specific benefit.
Area of Science:
- Behavioral Science
- Oral Health
- Psychology
Background:
- Gingivitis and plaque are common oral health issues.
- Behavioral interventions may offer novel approaches to improve oral hygiene.
- Acceptance and Commitment Therapy (ACT) is a psychological intervention that could be applied to health behaviors.
Purpose of the Study:
- To evaluate the efficacy of a brief Acceptance and Commitment Therapy (ACT) intervention in reducing gingivitis and plaque levels.
- To assess the long-term effects of ACT on oral health outcomes in young adults.
- To explore potential gender differences in response to the ACT intervention.
Main Methods:
- A parallel group randomized controlled trial (RCT) involving 135 caries-active young adults.
- Intervention group received two ACT sessions plus standard oral health information.
- Control group received standard oral health information only. Gingivitis and plaque were measured at baseline, 9, and 18 weeks.
Main Results:
- Both groups showed significant reductions in gingivitis and plaque over time.
- The ACT intervention was not significantly more effective than standard information alone in reducing these measures.
- Exploratory analyses indicated females in the ACT group had significantly greater improvements in gingivitis and plaque compared to males.
Conclusions:
- A brief ACT intervention did not demonstrate superior effectiveness over standard oral health information for improving oral health in young adults.
- ACT may have a beneficial impact on oral health, particularly among females.
- Further research is warranted to explore the specific mechanisms and applicability of ACT in oral health interventions.
