Abstract

Purpose: Individuals with impaired masticatory function tend to prefer soft foods, which results in decreased masticatory muscle activity. This study examined the association between the oral condition (number of teeth, occlusal force, and occlusal contact area) and dietary hardness using a daily dietary questionnaire.

Methods: This cross-sectional study evaluated 1841 participants aged 69-71 and 79-81 years. Registered dentists examined the number of teeth, occlusal force, and occlusal contact area. Dietary hardness was defined as the estimated masticatory muscle activity required for a habitual diet. Habitual diet during the preceding month was assessed using a brief self-administered diet history questionnaire. Confounding factors, such as age, sex, socioeconomic status, smoking habits, history of chronic diseases (hypertension, hyperlipidemia, and diabetes), and cognitive function were also evaluated. Multivariate linear regression analyses were performed to assess the association between dietary hardness and each oral condition.

Results: Occlusal force (standardized regression coefficients [β]=0.08, P < 0.01) and occlusal contact area (β=0.06, P < 0.01) were significantly associated with dietary hardness after adjusting for the confounding factors. Number of teeth was not significantly associated with dietary hardness. In addition, the associations between dietary hardness, sex, and a history of diabetes were stronger than those between dietary hardness and oral factors.

Conclusions: Occlusal force and contact area were significantly associated with dietary hardness as estimated from the masticatory muscle activity using a daily diet questionnaire.

日本老年人的牙齿数量、咬合力、咬合接触面积和饮食硬度之间的关系：SONIC 研究。

目的：咀嚼功能受损的人往往喜欢吃软的食物，从而导致咀嚼肌活动减少。本研究通过日常饮食问卷调查，研究了口腔状况（牙齿数量、咬合力和咬合接触面积）与饮食硬度之间的关系：这项横断面研究评估了 1841 名年龄在 69-71 岁和 79-81 岁之间的参与者。注册牙医检查了牙齿数量、咬合力和咬合接触面积。饮食硬度被定义为习惯饮食所需的估计咀嚼肌活动。前一个月的饮食习惯通过简短的自填式饮食史问卷进行评估。此外，还对年龄、性别、社会经济地位、吸烟习惯、慢性病史（高血压、高脂血症和糖尿病）和认知功能等干扰因素进行了评估。为评估饮食硬度与各种口腔状况之间的关联，进行了多变量线性回归分析：结果：调整混杂因素后，咬合力（标准化回归系数[β]=0.08，P < 0.01）和咬合接触面积（β=0.06，P < 0.01）与饮食硬度显著相关。牙齿数量与膳食硬度的关系不大。此外，饮食硬度、性别和糖尿病史之间的关联要强于饮食硬度和口腔因素之间的关联：咬合力和接触面积与膳食硬度显著相关，膳食硬度是通过每日膳食调查问卷中的咀嚼肌活动估算出来的。

期刊介绍： Journal of Prosthodontic Research is published 4 times annually, in January, April, July, and October, under supervision by the Editorial Board of Japan Prosthodontic Society, which selects all materials submitted for publication. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. The Journal will cover all diagnostic and clinical management aspects necessary to reestablish subjective and objective harmonious oral aesthetics and function. The most-targeted topics: 1) Clinical Epidemiology and Prosthodontics 2) Fixed/Removable Prosthodontics 3) Oral Implantology 4) Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology) 5) Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism) 6) Orofacial Pain and Temporomandibular Disorders (TMDs) 7) Adhesive Dentistry / Dental Materials / Aesthetic Dentistry 8) Maxillofacial Prosthodontics and Dysphagia Rehabilitation 9) Digital Dentistry Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, of orofacial trauma, or of a variety of dental and oral diseases and orofacial pain conditions. Reviews, Original articles, technical procedure and case reports can be submitted. Letters to the Editor commenting on papers or any aspect of Journal of Prosthodontic Research are welcomed.
