Dietary advice combined with prosthetic treatment could improve dietary intake earlier than prosthetic treatment only. This early improvement might signify early adaptation to new prostheses. Therefore, dietary advice might affect functional adaptation to new prostheses.
The aim was to clarify the influence of simple dietary advice on masticatory function of elderly individuals with new complete dentures.
A randomised controlled trial was performed on 59 edentulous elderly individuals who had received new complete dentures. Participants were randomly divided into an intervention group (received simple dietary advice: 15 men and 15 women, mean age: 74.8 ± 8.0 years) or a control group (received denture care advice: 15 men and 14 women, mean age: 78.6 ± 6.8 years). Masticatory function was assessed using colour-changeable chewing gum for mixing ability and test gummy jelly for shearing ability. Mixing and shearing ability were assessed at pre-treatment, and 3 and 6 months post-treatment. At each assessment time, mixing ability was compared using Student's t test and shearing ability using Mann-Whitney's U test. Within-group differences in mixing ability were analysed using repeated-measures one-way analysis of variance and those in shearing ability were analysed using Wilcoxon signed-rank test with Bonferroni correction.
At each assessment time, there was no significant difference in mixing or shearing ability between groups. In the intervention group, mixing and shearing ability significantly increased at 3 and 6 months post-treatment. In the control group, mixing ability significantly increased at 6 months post-treatment.
Simple dietary advice might lead to relatively early improvements in masticatory function.
饮食建议结合修复治疗可能比单纯修复治疗更早地改善饮食摄入。这种早期改善可能表明对新义齿的早期适应。因此，饮食建议可能会影响对新义齿的功能适应。
本研究旨在阐明单纯饮食建议对佩戴新全口义齿的老年患者咀嚼功能的影响。
对 59 名佩戴新全口义齿的无牙颌老年患者进行了一项随机对照试验。参与者被随机分为干预组（接受简单饮食建议：15 名男性，15 名女性，平均年龄：74.8±8.0 岁）或对照组（接受义齿护理建议：15 名男性，14 名女性，平均年龄：78.6±6.8 岁）。使用可变色咀嚼胶评估混合能力，使用测试胶评估剪切能力。在治疗前、治疗后 3 个月和 6 个月评估咀嚼功能。在每个评估时间点，使用学生 t 检验比较混合能力，使用曼-惠特尼 U 检验比较剪切能力。使用重复测量单因素方差分析分析混合能力的组内差异，使用 Wilcoxon 符号秩检验分析剪切能力的组内差异，并进行 Bonferroni 校正。
在每个评估时间点，两组的混合或剪切能力均无显著差异。在干预组中，治疗后 3 个月和 6 个月混合和剪切能力显著增加。在对照组中，治疗后 6 个月混合能力显著增加。
单纯饮食建议可能会导致咀嚼功能的相对早期改善。
