statement of problem: the role of the microbial plaque in caries etiology and periodontal diseases has been proved and the mechanical methods for plaque control have special limitations, consequently, chemical methods have been suggested. one of the most effective materials is chlorhexidine gluconate that is commonly used as mouth rinses. however, the medicated formulations of chewing gums, due...

The rate of caries has long been observed to be very low in the users of chewing-sticks even when they consume high carbohydrate diets. Recent researches have revealed that the chewing-sticks help in cleaning the teeth not simply due to mechanical removal of plaque but also due to their chemical constituents that possess the properties of whitening the teeth, protecting them from decay and remo...

HYPOTHESIS Gum chewing after elective open colon resection may stimulate bowel motility and decrease duration of postoperative ileus. DESIGN AND SETTING Prospective, randomized study in a community-based teaching hospital. PATIENTS Thirty-four patients undergoing elective open sigmoid resections for recurrent diverticulitis or cancer. MAIN OUTCOME MEASURES First feelings of hunger, time t...

INTRODUCTION The production of sufficient saliva is indispensable for good chewing. Recent research has demonstrated that salivary flow rate has little influence on the swallowing threshold. OBJECTIVES The hypothesis examined in the present study was that adding fluids to foods will influence chewing physiology. MATERIALS AND METHODS Twenty subjects chewed on melba toast, cake, carrot, pean...

BACKGROUND The purpose of this study was to determine the effect of three chewing gums and paraffin on the remineralization and the hardness of demineralized enamel. MATERIALS AND METHODS A total of 12 subjects wore intraoral palatal appliances with two demineralized bovine enamel slabs. The study consisted of four experimental periods each lasting 21-days, during which subjects were assigned...

RATIONALE Recent research suggests that chewing gum may increase alertness and lead to changes in cognitive performance. The present study examined effects of chewing gum on these functions within the context of a single study. OBJECTIVES This study had four main aims. The first was to examine whether chewing gum improved learning and memory of information in a story. The second aim was to de...

OBJECTIVES The finding that chewing gum can moderate state anxiety under conditions of acute stress has proved difficult to replicate. The present study examines the extent to which chewing gum can moderate state anxiety under conditions of acute social stress. METHOD In a between-participants design, 36 participants completed a task comprising a mock job interview (a variation on the Trier S...

objective: the use of sugar-free chewing gums has been reported to be highly effective in the prevention of dental caries. this study carried out to compare the effect of mastic gum and a xylitol chewing gum on remineralization of caries-like lesions. materials and methods: in this cross-over, single blinded, in situ study, first, artificial caries-like lesions were created in six extracted hum...

background and objectives: postoperative ileus is common after abdominal resection. it causes gas store,distention, nausea, vomiting, and even pain. this study examines the impact of gum chewing as a type of sham feeding on the duration of postoperative ileus. methods: in this randomized control trial study, 70 patients in two groups (each group n=35) underwent abdominal resection. the a group ...

The current series of experiments investigated the effects of the timing of gum chewing on cognitive function, by administering a battery of cognitive tasks to participants who chewed gum either prior to or throughout testing, and comparing their performance to that of controls who did not chew gum. Chewing gum was associated with performance advantages on multiple measures when gum was chewed ...
