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 ...

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...

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...

The proposition that chewing gum can improve alertness was investigated via both physiological and self-rated measures. The Pupillographic Sleepiness Test (PST) provided a measure of pupillary unrest (PUI); a physiological index of daytime sleepiness. Chewing gum reduced the extent of sleepiness as measured by both PUI and self-rated sleepiness. Specifically, in comparison with sham chewing and...

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...

State transitions in the chewing behaviour of six half-breed (Île de FrancexTexel) yearling female sheep (Ovis aries L.) were studied by using jaw movements recorded continuously over 5 days at the end of a number of experimental periods from 21 September 1992 to 4 April 1993. The sheep were housed in individual pens. Each of them received the same diet, that is, 250 g/day of concentrate mix (1...

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...
