Experimental stress analysis of dental structures has been a topic of interest during the past quarter century. The object of such research was the determination of stress distribution and improvement of the mechanical strength of these structures. Most of the stress analysis of dental structures was carried out using the photoelastic technique.1-8 A more recent method of stress analysis, origi...

o bjective : increased levels of oxidative stress markers in periodontitis have been reported by recent studies. malondialdehyde (mda) and superoxide dismutase (sod) are both in- creased during oxidative stress. the aim of this study was to detect and measure the level of oxidative stress markers in peri-implant crevicular fluid (picf). their correlation with peri-implant clinical parameters wa...

BACKGROUND The objective of this study was to investigate the stress distribution in the bone around zygomatic and dental implants for 3 different implant-retained obturator prostheses designs in a Aramany class IV maxillary defect using 3-dimensional finite element analysis (FEA). MATERIAL AND METHODS A 3-dimensional finite element model of an Aramany class IV defect was created. Three diffe...

Objective: To investigate the relationships between job characteristics, motivation, role stress and performance effectiveness of dental nurses in primary care units in the northeastern part of Thailand. Material and Method: A explanatory cross-sectional study was conducted in 326 dental nurses who were working in 310 PCUs of 19 provinces, 220 amphurs in the northeastern part of Thailand were t...

The aim of this study was to systematically review the available literature on the levels, causes, and impact of stress among dental students. The investigators searched eight electronic databases: Medline, Medline in process, Psychinfo, ERIC, Embase, Cochrane Library, Web of Science, and SCOPUS. Two independent reviewers conducted the selection, data extraction, and quality appraisal for inclu...

OBJECTIVE Stress among dental students can be a significant threat, resulting in physical and/or mental illness, and have a negative effect on students' performance and the professional practice of dentistry. Stress can occur from different sources. The purpose of this study is to test whether the year of study has an effect on the stress levels of dental students. METHOD Our study consisted ...

Background: Dental students who are at clinical or educational stage, are under environmental stress. The cumulative effect of clinical and educational stressors may also have negatively impact performance of clinical education in the long term and lead to mental and physical disorders. Our aim was to recognize and compare the stressful factors of dental environment among the students of clinic...
