Association between oral health and nutritional intake among older denture wearers

Le résumé fourni par la source

PURPOSE: This study examined the association between oral health and nutritional intake among older denture wearers. METHODS: Oral health parameters were evaluated in 114 denture wearers, including the number of remaining teeth (<20 or ≥20), posterior occlusal support (Eichner classification A1-B3 or B4-C3), objective masticatory assessment (glucose concentration: <100 or ≥100 mg/dL), subjective masticatory assessment (self-reported masticatory problems), and occlusal force (<500 or ≥500 N). Nutritional intake was assessed using a brief self-administered diet history questionnaire. Differences in nutritional intake according to oral health parameters were assessed using multiple regression analysis. RESULTS: Fewer remaining teeth were associated with higher total fat (β = 0.207, P = 0.038) and plant fat (β = 0.242, P = 0.017) intakes, and with lower carbohydrate (β = -0.264, P = 0.026) and cereal (β = -0.320, P = 0.002) intakes. The presence of masticatory problems and absence of posterior occlusal support were associated with lower intakes of plant protein (β = -0.311, P = 0.002) and meat (β = -0.232, P = 0.022), respectively. CONCLUSION: Among older denture wearers, denture design-related factors, such as the number of remaining teeth and posterior occlusal support, were associated with more nutritional intake items than oral function-related parameters.
