Abstrakt: Background: To date, no study has investigated the association between chewing function and related parameters as a function of the degree of dementia using a finer subdivision of the values of the Mini-Mental State Examination (MMSE).
Objective: This study aimed to investigate the differences in chewing function and related parameters as a function of the degree of dementia.
Methods: An analysis of cross-sectional data obtained from the OrBiD (Oral Health, Bite Force, and Dementia) pilot study was performed. The participants were stratified into five groups based on the outcomes of the MMSE (no dementia, MMSE 28-30; mild cognitive impairment, MMSE 25-27; mild dementia, MMSE 18-24; moderate dementia, MMSE 10-17; severe dementia, MMSE <10). The chewing efficiency, maximum occlusal force and related parameters (number of supporting zones, number of teeth, Eichner index, tooth/denture status, denture quality, and dental treatment needs) were recorded.
Results: The MMSE groups showed significantly different chewing efficiencies (p = .003, Jonckheere-Terpstra test) and maximum occlusal forces (p = .003, Jonckheere-Terpstra test), but the number of supporting zones (p = .055, chi-square test) and the number of natural teeth (p = .126, chi-square test) were not different. The Eichner index, tooth/denture status, denture quality and dental treatment need showed no significant associations with the degree of dementia.
Conclusion: An improvement in the usability of the measurement methods for assessing chewing function in people with dementia is needed. Research involving people with dementia is necessary because the nutritional situation often deteriorates rapidly within a multifactorial system, which includes chewing ability and oral health.
