The modulus of elasticity of dental amalgam has been determined by analysis of creep data (OGLESBY ET AL, J Res Natl Bur Stan 72C: 203, 1968) and by ultrasonic methods (DICKSON and OGLESBY, J Dent Res 46: 1475, 1967; HALL ET AL, J Dent Res 52: 390, 1973) to be between 63,000 and 70,000 MN/m2. These values represent the instantaneous elastic compliance term when dental amalgam is treated as a vi...

To persist in the oral cavity, bacteria must be able to tolerate rapid and substantial environmental fluctuations, particularly in pH and nutrient source and availability. Various species of Streptococcus, one of the most abundant genera in the mouth, are associated with oral health, as well as with dental caries. Cariogenic streptococci depend on a biofilm lifestyle for survival and persistenc...

PURPOSE The purpose of this study was to examine the relationship between asthma symptoms and dental anxiety, dental health attitudes, and physical symptoms and sensations such as watery eyes, upset stomach, headaches, and nausea in a group of adult dental patients with asthma. These variables are believed to be highly related to stress levels, which can exacerbate asthma symptoms during dental...

The aim of this study was to compare a group of children with high levels of anxiety during dental treatment who required physical restraint (group 1) to a group of children who collaborated with treatment (group 2). Child stress and its relationship with the manifestations of stress of the mothers and the dental students were assessed. The following psychological evaluation techniques were app...

The purpose of this study was to compare the results of different hierarchical models in engineering analysis applied to dentistry with 2D and 3D models of a tooth and its supporting structures under 100 N occlusal loading at 45° and examine the reliability of simplified 2D models in dental research. Five models were built from computed-tomography scans: four 2D models with Plane Strain and Pla...

Dental caries is an infectious microbiologic disease of the teeth that results in localized dissolution and destruction of the calcified tissue. Dental caries is a mulitifactorial disease, which is caused by host, agent, and environmental factors. Cariogenic micro-organisms enter the dental biofilm early in life and can subsequently emerge, under favorable environmental conditions, to cause dis...

[Purpose] The purpose of this study was to investigate the association between psychosocial stress, occupational stress, and musculoskeletal symptoms in Korean dental practitioners. [Subjects and Methods] Self-reported questionnaires were distributed to 401 dental practitioners in Korea. To assess the risk factors related to musculoskeletal disorders, the Nordic Musculoskeletal Questionnaire, t...

background : occupational stress is a psychosocial dimension of occupational health concept on social determinants of health, especially, job & environmental condition. recently, staff network of different government universities of thailand have called higher education commission, and ministry of education, thailand to resolve the issue of gov-ernment education policy (e.g. wage inequity, poor...
