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...

This was a single-center, prospective, cross-sectional study stratified by age and gender with the objective of determining the relationship between gum chewing history, salivary flow, and dental caries severity in adults. We enrolled 191 subjects aged 18-65 years who underwent assessments for gum chewing history, unstimulated salivary flow rate, salivary pH, and caries severity. Unstimulated s...

Objective This in situ study investigated the ability of a CPP-ACP chewing gum in preventing erosive enamel loss. Material and Methods: During three experimental crossover phases (one phase per group) of seven days each, eight volunteers wore palatal devices with human enamel blocks. The groups were: GI - Sugar free chewing gum with CPP-ACP; GII - Conventional sugar free chewing gum; and GIII -...

BACKGROUND Habitual khat chewing is a widespread male habit in Southern Arabia and East Africa. The aim of this study was to assess the effect of Khat chewing on oral hygiene and periodontal health status among Yemeni male khat chewers. MATERIAL AND METHODS This case- control study included 310 khat chewers, aged 20-65 years, and 72 age- and gender- matched non-chewers as controls. Periodonta...

background:dental caries is associated with oral pathogenes and streptococcus mutans (s. mutans)is one of the primary cariogenic organisms. the aim of this clinical study was to evaluate the effect of sugar free chewing gum containing casein phosphopeptide-amorphous calcium phosphate(cpp-acp) and xylitol on salivary streptococcus mutan.   m aterials and methods: 60 dental students, who voluntee...
