Development a new chewing problem directory and its validation for Korean elders

Abstract

Objectives This study aimed to develop a new chewing problem directory (CPD) and validate it with oral health indicators such as total occlusion force, number of natural and rehabilitated teeth (NRT), NRT posterior, natural teeth, natural teeth posterior, and dental status among Korean elders. Background Chewing problem is the main oral health problem in elders. However, there has been no validated tool using both subjective and objective assessment of chewing problem. Subjects and methods A total of 537 participants aged 65 years or more were randomly assigned into 2 subsamples: developing sample (n = 260) for developing and internally validating the new CPD as the 1st stage and confirmation sample (n = 277) for confirming validation of CPD as the 2nd stage. CPD was developed using three subjective questionnaires (general eating, chewing nuts, and chewing meat problem) and objective NRT. Periodontitis, age, sex, education, smoking, alcohol drinking, metabolic syndrome, and frailty were considered as confounders. Following the development of CPD, CPD was validated using multiple multivariable logistic regression after controlling for confounders in confirmation sample and total sample. Results The Cronbach’s alpha value for three subjective questionnaires of CPD was 0.87. Among oral health indicators, NRT (0–28) showed the highest impact association with subjective chewing problem score (partial r = − 0.276). The chewing problem from the new CPD was associated with all items of oral health indicators. The prevalence of chewing problems by CPD was 57.7% in developing sample. Elders with NRT ≤ 24, compared with those with NRT ≥ 25, showed the highest impact on chewing problems by new CPD (Odds Ratio = 7.3 in the confirmation sample and 5.04 in the total sample, p < 0.05) among oral health indicators. Conclusion This new CPD was developed as a valid tool to evaluate the chewing problem for Korean elders in dental clinics and community-based settings.

Association between Chewing Difficulty and Dietary Ca, Vitamin D, and Mg Intake in Korean Older Adults: 8th Korea National Health and Nutrition Examination Survey (KNHANES) (2020–2021)

“…There remains a debate about the accuracy of self-reported CD in older adults. Fortunately, a valid assessment tool for measuring chewing problems in the Korean older population has recently been developed [45].…”

Key genes associated with Alzheimer's disease and periodontitis

“…Periodontitis is a chronic in ammation of periodontal supporting tissues caused primarily by local factors, characterized by an immune response of the host to periodontal pathogens leading to destruction of the gingiva and tooth-supporting bone, with the age of onset being more common after 35 years of age. According to the World Health Organization, the prevalence of periodontitis in adults is about 50%, of which 10% suffer from severe periodontitis, and this prevalence increases sharply in adults over 65 years of age (Vu, Lee, & Kim, 2022). The in ammatory response also plays an important role in the pathogenesis of periodontitis.…”
