Filter by:The objective of this research is to evaluate the oral modifications caused by different types of coke drinks (regular coke and diet coke). The salivary and the dental biofilm pH will be determined in the first minutes after their consumption. Additionally, the bacterial proliferation of dental biofilm will be evaluated.
The study was carried out in 21 first grade primary school children, 100% aged 6 years, 52.4% were female. They were given 5 types of milk, each one was measured on different days (Monday cow's milk, Tuesday coconut milk, Wednesday almond milk, Thursday soy milk, Friday rice milk)
The laying of a naso-gastric tube is an extremely common event in intensive medicine; although standard naso-gastric tube laying is performed at the patient's bedside, this procedure is not without risk. Through the use of methods already used in the clinical field, of daily use, we want to identify the threshold value between tracheal and esophageal etCO2 (group A) and the threshold value between gastric and esophageal pH (group B).
Xerostomia is defined as the subjective complaint of dry mouth. Symptoms of dry mouth may range from mild oral discomfort to significant oral disease that can compromise patients' health, dietary intake and quality of life. Xerostomia is accompanied by numerous signs and symptoms mainly in the mucous membranes, lips, tongue, salivary glands and teeth. This study was designed to verify efficacy and safety of a novel dietary supplement (Aqualief),designed with the aim of stabilizing the saliva flux and pH at a neutral level and to improve the acid buffering capacity of saliva.
The diurnal variation in the flow of saliva and hence the composition of saliva is an established fact. Consumption of acidic and sweetened food and beverage is known to reduce the salivary pH and some of them reduce it to critical pH levels and result in structural damage to the hard tissues of the tooth. The purpose of this study is to ascertain the effect of the select commercially available test carbonated drink containing sugar on the salivary pH and assess the buffering capacity of the saliva with or without various intervention measures following the exposure to the test carbonated drink at different time intervals.

Consumption of most types of acidic and sweetened foods and beverages are known to reduce the pH of saliva and some of them even reduce it to critical pH levels and result in structural damage to the hard tissues of the tooth. The purpose of this study is to ascertain the effect of the selected commercially available test sweetened flavored milk drink on the salivary pH and assess the buffering capacity of the saliva with or without various intervention measures following the exposure to the test flavored milk drink at different time intervals.

The purpose of this study is to ascertain the effect of the selected commercially available test fruit-juice drink on the salivary pH and assess the buffering capacity of the saliva with or without various intervention measures following the exposure to the test fruit-juice drink at different time intervals.
This is a pilot study and will be used to power an NIH grant application on the effect of resistant starch on weight gain in children.
