Abstract
Purpose: Several studies have reported a close association between periodontal disease (PD) and diabetes mellitus (DM). In addition, the decline in masticatory function due to decreased occlusal support may worsen DM due to poor nutritional intake. We aimed to elucidate the relationship between PD, decreased occlusal support, and DM.
Methods: We surveyed 968 participants (411 men and 557 women) aged 50-79 years in the Suita study. An oral glucose tolerance test was performed with 75 g glucose, and fasting and 2 h post-challenge plasma glucose levels were measured. The participants were classified into following four groups: normal glucose tolerance, impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and DM. Occlusal support was evaluated by the Eichner Index. PD was assessed using the Community Periodontal Index, and participants were classified into two groups: without PD and with PD. Logistic regression analysis was performed using the incidence of IFG, IGT, and DM as objective variables in the without PD and PD groups.
Results: In the without PD group, body mass index (BMI) was significantly associated with IFG, IGT, and DM, and a history of hypertension was significantly associated with DM. In the PD group, male sex and BMI were significantly associated with IGT and DM, a history of hypertension was significantly associated with DM, and decreased occlusal support was significantly associated with IGT and DM.
Conclusions: Decreased occlusal support was associated with DM in patients with PD.
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.
