Mild cognitive impairment (MCI) is the stage between the expected cognitive decline of normal aging and the more serious decline of dementia. MCI should be clinically noted because it is likely to progress to dementia and thus may provide insight into the pathogenesis of dementia as a predementia stage. Previous long-term follow-up studies have shown that the rate of progression to dementia ranges from 10 to 80% among MCI patients | Mild cognitive impairment (MCI) is the stage between the expected cognitive decline of normal aging and the more serious decline of dementia.

Masticatory dysfunction refers to the decrease in or deterioration of masticatory function caused by a structural factor (e.g., number of remaining teeth, posterior occlusal contact), a functional factor (e.g., masticatory performance, bite force) or both combined. Meanwhile, subjective factors, such as the mental or psychological condition of an individual, could influence masticatory function | Masticatory dysfunction refers to the decrease in or deterioration of masticatory function caused by a structural factor (e.g., number of remaining teeth, posterior occlusal contact), a functional factor (e.g., masticatory performance, bite force) or both combined.

The number of remaining teeth has been suggested as a significant independent risk factor for cognitive impairment by explaining two possible mechanisms, i.e., neuroinflammation caused by increased proinflammatory mediator levels and malnutrition due to tooth loss [8, 13, 14]. In addition, a poor chewing ability and low occlusal force are significantly associated with cognitive function [10, 15, 16], and oral rehabilitation using prostheses, such as removable prostheses (RPs) or dental implants, is effective in preserving cognitive function [17]. | The number of remaining teeth has been suggested as a significant independent risk factor for cognitive impairment by explaining two possible mechanisms, i.e., neuroinflammation caused by increased proinflammatory mediator levels and malnutrition due to tooth loss [8, 13, 14].
