Asthma is a chronic infl ammatory condition of the airway, characterised by the presence of airfl ow obstruction which is variable over short periods of time, or is reversible with treatment. Medication comprises of bronchodilators, corticosteroids and anticholinergic drugs. Most asthma drugs are inhaled using various forms of inhalers or nebulizers. Inhaled drugs must be used regularly. The ef...

Dental erosion (erosive tooth wear) is the result of a pathologic, chronic, localized loss of dental hard tissue that is chemically etched away from the tooth surface by acid and/or chelation without bacterial involvement. Acids of intrinsic (gastrointestinal) and extrinsic (dietary and environmental) origin are the main etiologic factors. Tooth wear including dental erosion is not a new phenom...

Background and Objectives: Considering importance of food habits and possible roles of obesity in tooth decay, the present study was carried out to investigate relationships between dietary habits and body mass index (BMI) withtooth decay in 4–6 years old kindergartenchildrenin Ahwaz, Iran. Materials and Methods: In this descriptive-analytical study, 359 children were selected randomly from ...

A case of uncommon occupational dental erosion was reported in an individual who had worked in the war industry for twenty years. This occupation involved daily, at least 8 hours, inhalation of chromic acid being used for cleaning of barrel of cannons. The erosion manifested as dental sensitivity with excessive cervical erosion even with pulpal exposure in certain teeth. Moreover, due to the ad...

BACKGROUND Gastroesophageal reflux disease (GERD) affects 15-25% of children and adolescents in the United States. The diagnosis of GERD in children is complex as reported symptoms or symptom profiles have been found to be unreliable. Frequently, the diagnosis must be confirmed by objective tests such as pH monitoring or histological evidence of esophagitis on an esophageal biopsy. Dental erosi...

BACKGROUND Dental erosion (DE) is the loss of the hard tissues of the tooth produced by the action of gastric juice, pepsin and acid on the dental enamel, its frequency ranges from 5 to 53.41 %. In Mexico there are no reports on the frequency and possible association. OBJECTIVE To establish the prevalence of dental erosion and its relationship to GERD. PATIENTS AND METHODS Prospective, obse...

The quality of dental care and modern achievements in dental science depend strongly on understanding the properties of teeth and the basic principles and mechanisms involved in their interaction with surrounding media. Erosion is a disorder to which such properties as structural features of tooth, physiological properties of saliva, and extrinsic and intrinsic acidic sources and habits contrib...

The aim of the study was to investigate some aspects of the oral health of male Saudi military inductees with special reference to soft-drink consumption, dental erosion, caries and fluorosis prevalences; a second aim of the study was to develop a system for assessing dental erosion. The material comprised a random selection of 95 individuals with a mean age of 20.9 years (range, 19-25 years). ...

This in vitro study investigated the erosion-inhibiting properties of dental rinses during erosion in the presence of the salivary pellicle. The erosion inhibition by a Sn/F containing dental rinse (800 ppm Sn2+, 500 ppm F –, pH = 4.5) was compared with a fluoridated solution (500 ppm F –, pH = 4.5) and water(control). Calcium release and enamel softening were significantly reduced among enamel...

BACKGROUND The distribution of lesions from dental erosion due to intrinsic acid regurgitation and vomiting may be different from patterns of dental erosion due to extrinsic acids. To date studies have failed to validate this assumption. This study described the sites and nature of lesions from dental erosion in cases of intrinsic acid regurgitation, and compared them with the distribution of l...
