This study examined the prevalence of self-perceived chewing discomfort depending on the type of dental prosthesis used in South Korean adults. The subjects were 12,802 people over 20 years of age who participated in a health interview and dental examination. Chewing discomfort was examined using a self-assessed report with a structured questionnaire. Using multivariable logistic regression analysis, adjusted odds ratios were evaluated along with their 95% confidence intervals (α = 0.05). After adjusting for covariates, including age, gender, smoking, drinking, hypertension, diabetes, body mass index, education, income, and toothbrushing frequency, the odds ratios (95% confidence intervals) for chewing discomfort in groups without a dental prosthesis, with fixed dental prostheses, with removable partial dentures, and with removable complete dentures were 1 (reference), 1.363 (1.213-1.532), 2.275 (1.879-2.753), and 2.483 (1.929-3.197), respectively. The association between the prevalence of chewing discomfort and the type of dental prosthesis used was statistically significant even after adjusting for various confounders ( < 0.0001). The type of dental prosthesis was related to chewing discomfort among South Korean adults.
本研究旨在调查韩国成年人中，根据所使用的义齿类型，自我感知的咀嚼不适的流行情况。研究对象为 12802 名年龄在 20 岁以上的参与健康访谈和口腔检查的人群。咀嚼不适使用带有结构化问卷的自我评估报告进行检查。使用多变量逻辑回归分析，评估了调整后的优势比及其 95%置信区间（α=0.05）。在调整了年龄、性别、吸烟、饮酒、高血压、糖尿病、体重指数、教育、收入和刷牙频率等混杂因素后，无义齿、固定义齿、可摘局部义齿和可摘全口义齿组的咀嚼不适的比值比（95%置信区间）分别为 1（参考）、1.363（1.213-1.532）、2.275（1.879-2.753）和 2.483（1.929-3.197）。即使在调整了各种混杂因素后，义齿类型与咀嚼不适之间的关联仍然具有统计学意义（<0.0001）。义齿类型与韩国成年人的咀嚼不适有关。
