In recent years, the relationship between oral health status and various diseases has been increasingly reported worldwide, leading to a growing understanding of the importance of oral health. This study aimed to investigate the relationship between oral health status, determined after a dental health check-up, and chewing condition, determined via a questionnaire for specific health check-ups with the newly added chewing condition item-When you chew your food, which most accurately describes your chewing-.
From 20,834 Japanese workers who underwent dental health check-ups and specific health check-ups from April 2018 to March 2019, 4,011 male workers (51.2 ± 6.1 years, range 40-64 years) were extracted for this study. Participants were divided into two groups, the good chewing condition group (GCG) and poor chewing condition group (PCG), according to their responses to a questionnaire regarding chewing conditions. We collected and compared data on subjects' age, smoking status, number of teeth present, number of filled teeth, number of decayed teeth, number of missing teeth with prosthetic treatment, periodontal pockets, gingival bleeding, oral hygiene status, and Eichner's classification. Additionally, to clarify the risk associated with chewing condition, we performed stepwise multiple logistic regression analysis with good chewing condition/poor chewing condition as the dependent variable, and age, smoking status, number of teeth present, number of filled teeth, number of missing teeth with prosthetic treatment, periodontal pockets, oral hygiene status, and Eichner's classification as the independent variables.
The result of stepwise multiple logistic regression analyses, the odds ratio (OR) and 95% confidence interval (95% CI) of the factors that remained in the final model were as follows; the number of decayed teeth (OR = 1.18 [95% CI: 1.12-1.24]); periodontal pockets of 3 mm or less vs. 6 mm or more (OR = 1.63 [95% CI: 1.12-2.37]); Eichner's classification A1 vs. A2 (OR = 1.40 [95% CI: 1.08-1.82]), A3 (OR = 1.66 [95% CI: 1.09-2.52]), B1 (OR = 3.38 [95% CI: 2.04-5.61]), B2 (OR = 5.26 [95% CI: 2.46-11.2]), B3 (OR = 4.28 [95% CI: 1.20-15.2]), B4 (OR = 7.59 [95% CI: 1.06-54.5]).
The results of this study suggest a significant association between the newly added "chewing condition" item in the questionnaire for specific health check-ups and oral status; the number of decayed teeth, periodontal pockets, Eichner's classification.
近年来，全球范围内越来越多地报道了口腔健康状况与各种疾病之间的关系，这使人们对口腔健康重要性的认识不断加深。本研究旨在调查牙科健康检查后确定的口腔健康状况与通过新增咀嚼状况项目（“当您咀嚼食物时，以下哪项最能准确描述您的咀嚼情况”）的特定健康检查问卷所确定的咀嚼状况之间的关系。
从2018年4月至2019年3月接受牙科健康检查和特定健康检查的20834名日本工人中，提取了4011名男性工人（年龄51.2±6.1岁，范围40 - 64岁）进行本研究。根据参与者对咀嚼状况问卷的回答，将其分为两组，即良好咀嚼状况组（GCG）和不良咀嚼状况组（PCG）。我们收集并比较了受试者的年龄、吸烟状况、现存牙齿数量、补牙数量、龋齿数量、接受修复治疗的缺失牙数量、牙周袋深度、牙龈出血、口腔卫生状况以及艾希纳分类等数据。此外，为了阐明与咀嚼状况相关的风险，我们以良好咀嚼状况/不良咀嚼状况作为因变量，年龄、吸烟状况、现存牙齿数量、补牙数量、接受修复治疗的缺失牙数量、牙周袋深度、口腔卫生状况以及艾希纳分类作为自变量进行逐步多元逻辑回归分析。
逐步多元逻辑回归分析结果显示，最终模型中保留的因素的比值比（OR）和95%置信区间（95%CI）如下：龋齿数量（OR = 1.18 [95%CI：1.12 - 1.24]）；3mm及以下与6mm及以上的牙周袋（OR = 1.63 [95%CI：1.12 - 2.37]）；艾希纳分类A1与A2（OR = 1.40 [95%CI：1.08 - 1.8])、A3（OR = 1.66 [95%CI：1.09 - 2.52])、B1（OR = 3.38 [95%CI：2.04 - 5.61])、B2（OR = 5.26 [95%CI：2.46 - 11.2])、B3（OR = 4.28 [95%CI：1.20 - 15.2])、B4（OR = 7.59 [95%CI：1.06 - 54.5]）。
本研究结果表明，特定健康检查问卷中新增的“咀嚼状况 ”项目与口腔状况（龋齿数量、牙周袋深度、艾希纳分类）之间存在显著关联。
