Edentulous denture-wearers eat fewer fruits and vegetables than do comparable dentate individuals. Improved chewing ability with new dentures has resulted in little dietary improvement, suggesting that dietary intervention is necessary. The objective of this randomized controlled trial was to have a positive impact upon dietary behavior of patients receiving replacement complete dentures through a tailored dietary intervention. Readiness to change diet (Stage of Change), intake of fruits, vegetables, and nutrients, and chewing ability were assessed pre-and 6 weeks post-intervention. The intervention group (n = 30) received two dietary counseling sessions; the control group (n = 28) received current standard care. Perceived chewing ability significantly increased in both groups. There was significantly more movement from pre-action into action Stages of Change in the intervention group, who had a greater increase in fruit/vegetable consumption (+209 g/d) than did the control group (+26 g/d) (P = 0.001). Tailored dietary intervention contemporaneous with replacement dentures can positively change dietary behavior.
无牙颌义齿佩戴者比有牙的同龄人摄入的水果和蔬菜更少。使用新义齿后咀嚼能力有所改善，但饮食改善甚微，这表明饮食干预很有必要。这项随机对照试验的目的是通过量身定制的饮食干预，对接受全口义齿修复的患者的饮食行为产生积极影响。在干预前和干预后6周评估改变饮食的意愿（改变阶段）、水果、蔬菜和营养素的摄入量以及咀嚼能力。干预组（n = 30）接受了两次饮食咨询；对照组（n = 28）接受当前的标准护理。两组的感知咀嚼能力均显著提高。干预组从行动前阶段转变为行动阶段的人数显著更多，其水果/蔬菜摄入量的增加幅度（+209克/天）大于对照组（+26克/天）（P = 0.001）。与义齿修复同时进行的量身定制饮食干预可以积极改变饮食行为。
