BACKGROUND The deleterious effects of chewing betel quid (BQ) with or without tobacco on periodontal health are poorly addressed. The aim of this study was to investigate the severity and extent of periodontal disease among individuals chewing BQ with and without tobacco. METHODS One hundred twenty individuals (70 BQ chewers: 35 with tobacco and 35 without tobacco) and 50 control individuals ...

This study aims to quantitatively clarify the physiological features in rhythmically coordinated jaw and neck muscle EMG activities while chewing gum using EMG-EMG transfer function and EMG-EMG coherence function analyses in 20 healthy subjects. The chewing side masseter muscle EMG signal was used as the reference signal, while the other jaw (non-chewing side masseter muscle, bilateral anterior...

The aim of this study was to characterize the kinematics and masseter muscle activation in unilateral posterior crossbite. Eighty-two children (8.6 +/- 1.3 yr of age) with unilateral posterior crossbite and 12 children (8.9 +/- 0.6 yr of age) with normal occlusion were selected for the study. Electromyography (EMG) and kinematics were concurrently recorded during mastication of a soft bolus and...

SUMMARY The aim of this study was to compare the electromyographic (EMG) characteristics of masticatory muscles in children with either a skeletal or dentoalveolar open bite, compared with a control group (CG). Forty-five children (31 boys and 14 girls), aged 6-11 years, were included in the study, 15 with a skeletal anterior open bite (SAOB), 15 with a dentoalveolar anterior open bite (DAOB), ...

26 The orexins (Orexin-A and orexin-B) are neuropeptides which are secreted from 27 neurons in the lateral hypothalamus, which participate in the regulation of feeding 28 behavior. It remains to be determined, however, how the orexins exert their effects on 29 feeding behavior, including masticatory movements. To this end, we analyzed food 30 intake behavior and masticatory muscle activity usin...

BACKGROUND Betel nut chewing is related to several kinds of cancer, metabolic syndrome, and type 2 diabetes. Whether it is associated with a greater risk of cardiovascular disease (CVD) and all-cause mortality, however, remains unclear. OBJECTIVE We aimed to investigate the association between betel nut chewing and CVD and all-cause mortality. DESIGN A baseline cohort of 56,116 male partici...

In the attempt to lower the sugar consumption in population is to exchange the number of sugar sweeteners which manufacture produced for used in foods, drinks and candy with non-sugar sweetener as xylitol. Xylitol is effective as noncariogenic substitutes for use in place of glucose. Objectives: A clinical trial was carried out to investigate the effect of sugar candy containing xylitol inhibit...

New formulations and technologies have been developed through oral drug delivery systems' researches. Such researches display significance of oral route amongst patients. We've reviewed all the features associated with medicated chewing gum as a modern drug delivery by introducing the history, advantages and disadvantages, methods of manufacturing, composition differences, evaluation tests and ...

Developmental changes in the coordinative organization of masticatory muscles were examined longitudinally in four children over 49 experimental sessions spanning the age range of 12-48 mo. Electromyographic (EMG) records were obtained for right and left masseter muscles, right and left temporalis muscles, and the anterior belly of the digastric. Two independent analytic processes were employed...

Tobacco smoking, betel quid chewing and alcohol drinking are oral cancer risk factors. Observational studies unanimously report that oral cancer risk in smoking-drinking-chewing exposed subjects is exceptionally high. However, none of them assessed the fractions of this risk attributable to the three individual risk factors and to the smoking-drinking-chewing interaction. The present study soug...
