background: green tea contains phenolic compounds which could be considered as an anticariogenic agent. in addition, there has not been any significant side effect reported compared to sodium fluoride. so it seems that any comparison between the effects of green tea extract on the level of cariogenic bacteria with sodium fluoride is beneficial. the purpose of this study was to compare the effec...

Two winter-insulated Norwegian reindeer (Rangifer tarandus tarandus) were exposed to air temperatures of 10, 20, 30, and 38 degrees C while standing at rest in a climatic chamber. The direction of airflow through nose and mouth, and the total and the nasal minute volumes, respectively, were determined during both closed- and open-mouth panting. The animals alternated between closed- and open-mo...

OBJECTIVE Many studies report a significant relationship between the one-leg standing time with the eyes open and the occlusal relationship. To determine the association between proprioception (the periodontal membrane vs muscle spindle) to the one-leg standing time, the authors compared the one-leg standing time with eyes open between mouth-opened and mouth-closed conditions. METHODS The stu...

Saliva is secreted into the mouth at a rate of 0.3 to 0.4 ml per minute. Retained saliva in the mouth physiologically triggers swallowing to carry the saliva out of the mouth. Dawes (1983) have reported the volume of saliva in the mouth just before swallowing, the rate of swallowing, the volume swallowed per swallow, and the volume of saliva in the mouth just after swallowing. Clearance of mate...

introduction: according to the prevalence of sore mouth, its outcome and possible role of anemia in its etiology and some contradictions in this theory, our study was performed to evaluate the role of iron deficiency anemia as a etiological factor for sore mouth. materials and methods: this historical cohort study was performed on 40 cases, including 20 anemic patients as the experimental group...

BACKGROUND Timely mouth-to-mouth ventilation is critical to resuscitate drowning victims. While drowning is frequent, there are no lay persons trained in cardio-pulmonary resuscitation (CPR) in rural Bangladesh. As part of a feasibility study to create a first response system in a conservative Islamic village environment, a pilot was undertaken to examine willingness to provide mouth-to-mouth v...

A mouth is present in all animals, and comprises an opening from the outside into the oral cavity and the beginnings of the digestive tract to allow eating. This review focuses on the earliest steps in mouth formation. In the first half, we conclude that the mouth arose once during evolution. In all animals, the mouth forms from ectoderm and endoderm. A direct association of oral ectoderm and d...
