this study compared diet and regular coca-cola on enamel erosion in cold and room temperatures.seventy five enamel specimens were prepared and divided into 5 equal groups (n=15) as follows: group 1: regular beverage at room temperature, group 2: regular beverage at refri-gerator temperature, group 3: diet beverage at room and group 4: diet beverage at refrige-rator temperature. the specimens we...

Dental caries and the severity (depth) and area of erosions of tooth substance were studied in 11 bulimic subjects and 22 matched controls. Erosions were seen in 69% of the bulimics' teeth and in only 7% of the controls' (p less than 0.001). Depth of penetration was greater in the bulimics, extending even into the pulp, and the area of erosion was also larger. Scores for dental caries were high...

BACKGROUND Dental erosions are determined by a mechanism involving increased oral acidity. Gastro-esophageal reflux disease (GERD) represents the pathological reflux of gastric content into the oral cavity, affecting the hard dental tissues integrity, with a major risk of advanced tooth wear. AIM This study aims to investigate the prevalence of dental erosions in GERD patients, in order to ob...

BACKGROUND/AIMS Gastroesophageal reflux disease (GERD) is common in children. Recurrent exposure to gastric acid in GERD may contribute to tooth erosion. METHODS In this prospective study, 54 GERD patients qualified according to endoscopy, pH-metry, and the GERD questionnaire and 58 healthy controls qualified by the GERD questionnaire were assessed. Two groups underwent dental evaluations for...

animal models for h.pylori infection have been developed to clarify the pathogenesis, testing new therapies and developing vaccines against human h.pylori infection. although rats have been used extensively for gastric ulceration and acid secretion studies, the animal is not normally infected with h.pylori.several chemicals such as ethanol and ammonium hydroxide can induce gastric erosion and i...

Dental fluorosis is the result of chronic endogenic intake of fluorides in amounts exceeding the optimal daily dose of 1 ppm In our country different mineral waters with high content of fluorine are on the market. As a result in numerous regions and settlements the cases of fluorosis with different degrees of seriousness have become more frequent in recent years. The aim of this study is to tes...
