BACKGROUND/OBJECTIVES Chewing difficulty is a factor contributing to a poor nutritional status in the elderly. The aim of this study was to examine disparities in food and nutrition intakes among Korean elderly people with and without chewing difficulty. SUBJECTS/METHODS This study utilized data from the sixth Korea National Health and Nutrition Examination Survey conducted in 2013. The study...

PURPOSE To assess possible associations between occlusal parameters and comminution of solid food during chewing in a group of completely dentate subjects. MATERIALS AND METHODS Twenty-five completely dentate volunteers (28 teeth, 14 functional dental units) aged 24-50 yrs, without any complaints of the stomatognathic system participated in this study. An Optosil test was used to estimate mas...

BACKGROUND Mastication is the first step in ingesting food, but the effects of mastication on energy intake and gut hormones in both obese and lean subjects have not been extensively evaluated. OBJECTIVE The current study aimed to compare the differences in chewing activities between obese and lean subjects and to examine the effects of chewing on energy intake and gut hormone concentrations ...

materials and methods in a randomized clinical trial, 60 patients, scheduled for cesarean section were randomly divided in to 2 groups gum-chewing group (n = 30) and control group (n = 30) postoperatively. the patients in the gum-chewing group postoperatively chewed sugar free gum 3 times daily each time for 1 hour until discharge. the patients' demographic characteristics, duration of sur...

Occlusion is an important factor that affects chewing. Unilateral posterior crossbites (UPXBs) have been reported to be one of the most prevalent malocclusions in the primary dentition and patients with UPXBs show abnormal condylar motion on the crossbite side in the mediolateral direction during mastication. The aims of this study were to investigate the characteristics of common chewing cycle...

Recent research examined the effects of chewing gum on attention and reported a significant interaction of gum chewing with time. Using a crossover within-subject design, the present study examined the effect of gum chewing on sustained attention in healthy adults over a period of 30 min. The results revealed a significant main effect of time and a significant interaction between gum chewing an...

PURPOSE The purpose of this investigation was to describe age- and consistency-related changes in the temporal characteristics of chewing in typically developing children between the ages of 4 and 35 months and adults using high-resolution optically based motion capture technology. METHOD Data were collected from 60 participants (48 children, 12 adults) across 5 age ranges (beginners, 7 month...

This study aimed to assess self-reported chewing ability among a sample of Sudanese adults and to identify factors associated with impaired oral function. A total of 1,888 adults (≥16 years old) attending outpatient clinics in Khartoum State were included. Subjective chewing ability was assessed by interviewing participants on chewing complaints and perceived difficulty of chewing 15 common Sud...

BACKGROUND One of the most immediate and important functional consequences of many oral disorders is a reduction in chewing ability. The ability to chew is not only an important dimension of oral health, but is increasingly recognized as being associated with general health status. Whether perceived chewing ability and oral health-related quality of life (OHRQoL) are correlated to a similar deg...
