The aim of the present study was to evaluate the effect of a brief version of the behavioral intervention Acceptance and Commitment Therapy (ACT) on reducing gingivitis and plaque levels after 18 weeks.
One hundred thirty-five caries-active young adults (18-25 years of age), recruited from two public dental clinics, participated in this parallel group randomized control trial (RCT). Participants in the intervention (n = 67) received two ACT sessions in combination with standard information on oral health, and participants allocated to the control group (n = 68) received standard information only. Gingivitis and plaque levels were recorded at baseline and at the 9- and 18-week follow-ups. The effect of the intervention versus standard information alone was analyzed by intention-to-treat and per protocol, applying the General Linear Model (GLM). Exploratory analyses for the intervention and control groups were conducted to evaluate the effect of gender and smoking habits on the gingivitis and plaque outcome. The CONSORT guidelines for RCT were followed.
A significant decrease in gingivitis and plaque levels was observed over time, irrespective of treatment allocation. However, the ACT intervention was not significantly more effective at reducing gingivitis and plaque scores than standard information alone, even though the intervention participants had maintained their improvement to a greater extent. The exploratory analysis revealed that females improved their gingivitis and plaque levels significantly more than the males in the intervention group (p = 0.025 for gingivitis and p = 0.013 for plaque).
A brief ACT intervention was not proven to be more effective than standard information alone at improving oral health in a sample of young adults with poor oral health. However, ACT seems to have a positive effect on oral health among females. (TRN ISRCTN15009620).
本研究旨在评估简短版行为干预接纳与承诺疗法（ACT）对减少 18 周后牙龈炎和菌斑水平的影响。
本平行组随机对照试验（RCT）共招募了 135 名来自两家公立牙科诊所的龋齿活跃的年轻成年人（18-25 岁）。干预组（n=67）接受了两次 ACT 治疗，同时还接受了口腔健康的标准信息，对照组（n=68）仅接受了标准信息。基线时、9 周和 18 周随访时记录了牙龈炎和菌斑水平。采用一般线性模型（GLM），通过意向治疗和方案分析，分析干预与标准信息单独治疗的效果。对干预组和对照组进行了探索性分析，以评估性别和吸烟习惯对牙龈炎和菌斑结果的影响。本研究遵循 RCT 的 CONSORT 指南。
无论治疗分配如何，随着时间的推移，牙龈炎和菌斑水平均显著下降。然而，ACT 干预并不能显著降低牙龈炎和菌斑评分，与单独提供标准信息相比没有显著差异，尽管干预组的参与者在更大程度上保持了改善。探索性分析表明，干预组中女性的牙龈炎和菌斑水平改善明显大于男性（牙龈炎：p=0.025；菌斑：p=0.013）。
与单独提供标准信息相比，简短版 ACT 干预并不能更有效地改善口腔健康状况较差的年轻成年人的口腔健康。然而，ACT 似乎对女性的口腔健康有积极影响。（TRN ISRCTN15009620）。
