A lower maximum bite force is a risk factor for developing cardiovascular disease: the Suita study

Abstract

Decreases in masticatory function are believed to be related to the development of cardiovascular disease (CVD) through inappropriate nutritional intake. This study focused on maximum bite force (MBF), which is an objective, quantitative index of masticatory function, and its association with the development of CVD (stroke and coronary heart disease) was investigated. The subjects were 1547 participants of the Suita study with no history of CVD who underwent medical and dental health examinations between June 2008 and June 2013. In addition to undergoing a basic physical examination at baseline, their MBF was measured. They subsequently underwent follow-up surveys for the development of CVD (mean follow-up, 3.5 years). The association between baseline MBF and the development of CVD was investigated by multivariate adjustment using a Cox proportional hazards model. CVD developed in 32 subjects during follow-up. The trend test showed a significant association between baseline MBF and CVD in a model that combined men and women. When analysed by sex, the trend test found a significant association between baseline MBF and CVD in women. Low MBF, which is an objective and quantitative index of masticatory function, may be a risk factor for the development of CVD.

Association of Non-carious Cervical Lesions With Oral Hygiene Aspects and Oclusal Force

“…In the present study, when comparing the bite force between men and women, it was observed that in both case and control groups the mean values of bite force were higher for males. These ndings are in accordance with several studies [37,42,47,[50][51][52][53][54][55], where a greater bite force was also found in men. Patients included in the present study were interrogated about their use of mouthwash, brushing habits such as frequency, hardness of bristles, type of toothpaste, and brushing technique.…”

Assessment of Occlusal Force and Local Gas Release Using Degradable Bacterial Cellulose/Ti3C2Tx MXene Bioaerogel for Oral Healthcare

“…Dental dyskinesia (degradation of masticatory function) and the resulting insufficient nutritional intake may result in cardiovascular disease. 7 Occlusal force has been mainly used to study masticatory mechanics and evaluate the masticatory function of patients before and after orthognathic surgery. In clinical medicine, force sensors are used to measure the dynamic changes of occlusal force and occlusal contact in different treatment stages.…”

“…Common dental diseases not only affect swallowing, speech, and other physical activities but also harm psychological health. − Among them, masticatory motor dysfunction has a severe impact on a person’s quality of life. Dental dyskinesia (degradation of masticatory function) and the resulting insufficient nutritional intake may result in cardiovascular disease . Occlusal force has been mainly used to study masticatory mechanics and evaluate the masticatory function of patients before and after orthognathic surgery.…”

Tooth Loss Related with Prevalence of Metabolic Syndrome in a General Urban Japanese Population: The Suita Study

“…Hashimoto et al [ 45 ], who conducted a follow-up study in the same field as this study, reported that decreased occlusal force increased the risk of new-onset of cardiovascular disease. Even if the number of teeth decreases, prosthodontic treatment can recover masticatory performance [ 46 ].…”
