Research Abstract

Loss of posterior occlusal support was associated with a reduced bite force and a decline in masticatory performance. Among males, occlusal support was significantly associated with intake of green vegetable, fruit, and calcium, vitamin C as nutrient components. After controlling for age, gender and baseline oral-health-related quality of life, participants who had lost teeth or experienced a decline in occlusal force after 7 years had poorer OHRQoL. Unfavourable changes in clinical oral status over time are reflected in poorer self-rated oral health.
