The efficacy of cognitive-behavioral intervention on anxiety and oral health-related quality of life in adult orthodontic patients

Abstract

Objective To explore the influence of cognitive-behavioral intervention on the anxiety and oral health-related quality of life in adult orthodontic patients. Methods 152 adult orthodontic patients whose MDAS scores were greater than 11 were divided into the intervention group and the control group according Multistage Grouping Process. The former were treated with MBT appliance combined with cognitive-behavioral intervention, and the latter were treated with MBT appliance only. The State-Trait Anxiety Inventory(STAI) was adopted to evaluate anxiety in all patients during orthodontic treatment, and the UK oral health-related quality of life questionnaire(OHRQoL-UK) was adopted to evaluate the oral health-related quality of life in all patients before and after orthodontic treatment, respectively. Results 1.After 3 and 6 months cognitive-behavioral intervention, the scores of SAI in the intervention group(50.37±9.18, 35.65±8.92) were significantly reduced compared to the control group(56.62±10.52, 54.13±10.03) (P<0.01). After 6 months cognitive-behavioral intervention, the scores of TAI in the intervention group(47.92±6.82) were significantly reduced compared to the control group(51.52±7.41) (P<0.05). 2. After the orthodontic treatment, the scores of OHRQoL-UK in the intervention group(58.27±13.43) were significantly improved compared to the control group(51.99±11.69) (P<0.01). 3. The oral health-related quality of life after the orthodontic treatment were significantly related to post-treatment anxiety of adult orthodontic patients(r=-0.192~-0.459, P<0.05 ). Conclusion Cognitive-behavioral intervention can effectively reduce anxiety and improve the oral health-related life quality in the adult orthodontic patients.
