AI Article Synopsis
- This study examined how changes in chewing ability (masticatory performance) relate to the onset of diabetes in older adults from Japan over a 5-year period.
- It involved 214 participants, where those with declining chewing abilities were found to have a significantly higher risk of developing diabetes.
- The findings suggest that poorer chewing performance may contribute to the risk of diabetes, highlighting the importance of maintaining oral health in older age.
Article Abstract
Objective: Although masticatory performance is affected by age-related reduction in number of teeth (or treatment), the relationship between longitudinal changes in masticatory performance and diabetes mellitus is unknown. This longitudinal study investigated the association between changes in masticatory performance and new-onset diabetes mellitus among community-dwelling Japanese older adults.
Methods: The data of 214 older adults living in Ohnan Town, Shimane, Japan, who participated in two surveys conducted between 2012 and 2017 were analyzed. Diabetes mellitus was defined as a hemoglobin A1c level ≥ 6.5% or self-reported diabetes mellitus. The masticatory performance (measured by number of gummy jelly pieces collected after chewing) was evaluated by dental hygienists. Masticatory performance was categorized into two groups (high or low) based on the median in each survey; further, four groups (Group A: remained consistently high, Group B: changed from low to high, Group C: remained consistently low, Group D: changed from high to low) were used to determine longitudinal changes in masticatory performance. Logistic regression was used to analyze the association between changes in masticatory performance and new-onset diabetes mellitus.
Results: Overall, 10.3% of participants had diabetes mellitus at the follow-up survey. Multivariate analysis showed that Group D (odds ratio 8.69, 95% confidence interval 1.98-38.22) was positively associated with the development of diabetes mellitus compared with Group A after adjusting for sex, age, body mass index, alcohol consumption, physical activity, and eating speed.
Conclusions: Deteriorating masticatory performance for 5 years may cause diabetes mellitus among older adults.

Background Dental caries is identified as one of the most prevalent chronic pathologies among the pediatric population on a global scale, constituting a public health problem. Within the permanent dentition, the first molars play a fundamental and critical role both in masticatory functionality and in the development of occlusion and the overall oral health of the patient. Previous research has shown that permanent molars tend to show significantly high levels of caries incidence, and a correlation has been detected between the status of the first permanent molars and the overall caries rate.

Hemangiomas are benign congenital vascular tumors that commonly arise in the head and neck regions. Although they present with indolent growth and involution in most cases, they can cause facial deformities. Hemangiomas have three subtypes: capillary, cavernous, and mixed.

It is important to investigate the changes in the masseter muscle, one of the chewing muscles, in epilepsy patients and to determine whether epilepsy can be effectively predicted on muscle. The aim of this study is to measure masseter muscle thickness, circumference and cross-sectional area in individuals with epilepsy and healthy individuals. This study was performed with 128 individuals (64 epilepsy patients and 64 healthy subjects) aged between 18 to 59 years.

: Although there has been extensive research on the orofacial morphologic effects of cleft lip and palate (CLP), the effects of CLP on mandibular structures remain largely unknown. The aim of this study was to investigate the trabeculation differences in the mandibular osseous architecture of patients with bilateral CLP (BCLP) and left-sided unilateral CLP (UCLP) using fractal dimension (FD) analysis and to compare these findings with healthy controls without CLP. : A total of 63 patients (27 females, 36 males) with a mean age of 9.
