ackground and aim: it is important to evaluate the effect of the type of filling material on deformation and strength of tooth after filling and also the effect of filling depth on quality of restoration of a decayed tooth. material and methods: the orthopantomogram (opg) of the first and second molars of a 28-year-old man was made and the teeth were 3d modeled. the stress-deformation analysis ...

In Japan, the increasing frequency of mental health problems in postgraduate dental trainees has recently become apparent. To our knowledge, there has been no previous research to investigate the influence of the type of training program on the mental health of dental residents during one year of postgraduate clinical training. Therefore, the purpose of this study was to compare changes in the ...

BACKGROUND As dental implants receive masticatory stress, the distribution of stress is very important to peri-implant bone homeostasis and implant survival. In this report, we created a saddle-type implant and analyzed its stability and ability to distribute stress to the surrounding bone. METHODS The implants were designed as a saddle-type implant (SI) that wrapped around the alveolar bone,...

This study was conducted to identify the prevalence of stress, types of stressors, consequences of stress and stress relievers among undergraduate dental students at the University of Malaya during the different years of study. A descriptive cross-sectional quantitative study was conducted using a self-administered questionnaire among Bachelor of Dental Surgery students during Years 2 to 5. A 1...

AIM To evaluate the short-term follow-up outcome in four subgroups of uncooperative child dental patients referred to a specialist paediatric dental clinic in Sweden. METHODS Seventy children, classified into four groups (based on fear, temperament, behaviour and verbal intelligence), were followed-up at their public dental clinics after termination of specialist dental treatment. Questionnai...

This study investigated stress levels and health-promoting attributes (sense of coherence, social support, and coping strategies) in dental students using a Salutogenic approach. All dental students (n=2,049) from two Australian universities, two Chilean universities, and one New Zealand university were invited to participate in this cross-sectional study. The questionnaire covered sociodemogra...

Introduction: In the last decade dental implant has become crucial beneficial modalities. Many clinical dental implant systems have been established which can be used as the individual form of therapy or it may function together with other dental treatment methods. In this study we highlighted the role of AGEs and oxidative stress in terms of lipid peroxidation (TBARS) in the progression of per...

The objective of the present study is to evaluate how the elastic properties of the fabrication material of dental implants influence peri-implant bone load transfer in terms of the magnitude and distribution of stress and deformation. A three-dimensional (3D) finite element analysis was performed; the model used was a section of mandibular bone with a single implant containing a cemented ceram...

BACKGROUND The media repeatedly portrays dentists and other health professionals as being at risk of committing suicide. While this message often is accepted without question, there are little reliable data available that verifies this alleged risk. The relationship between professional stress and suicide, if any, has not been substantiated or quantified. TYPES OF STUDIES REVIEWED The author ...
