BACKGROUND Students of health-professions suffer high levels of stress and burnout. The aim of the present study was to evaluate the relationship between perceived stress latent factors ('tenseness' and 'frustration') and the features ('overload', 'lack of development' and 'neglect') of the three burnout subtypes ('frenetic', 'under-challenged' and 'worn-out', respectively), in a sample of Span...

The main purpose of this paper has been to discuss the effects of psychological stress and other environmental factors on incidence of diseases. We were specifically concerned with stress that increased susceptibility of uninfected hosts when exposed to infection. If such stresses also reduced resources, fecundity and/or survivorship, there was a reduction in the host carrying capacity. In addi...

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...

Dental caries (DC) is a local disease, which occurs on hard tissues of teeth leading to its destruction by oral microorganisms. Various environmental factors affect dental caries prevalence, which are diet, especially sucrose rich; demographic factors such as age and sex and improper brushing habits. Caries is a biosocial disease, as living standards improve the severity of the disease usually ...

CONFLICT OF INTEREST NONE DECLARED Waste management is one of the key ecological challenges of the modern world. As dental practitioners, we must recognize that some of the materials and procedures we use to provide dental health services may present challenges to the environment. Realizing this, we can begin to take measures to minimize the production of these wastes and their potential enviro...

Biofilms form rapidly on dental unit waterlines. The specific design of dental units favors bacteria to colonize surfaces and to form biofilm in water supply tubes, including dental unit water line (DUWL). The majority of the organisms in the biofilm are harmless environmental species, but some dental units may harbour opportunistic respiratory pathogens. Microbiological control of dental unit ...

Common environmental chemicals, drugs, or physical agents can adversely affect human teeth during their embryonic development and after their eruption into the oral cavity. One of the more common elemental toxicants is lead. Teeth are known to accumulate lead during their development. Both animal and human studies have shown that teeth with high lead levels are generally more susceptible to den...

The assessment of indoor air volatile organic compounds (VOCs) concentration levels in dental settings has a big health relevance for the potentially massive occupational exposure to a lot of diverse contaminants. The comparison of the VOCs profile relative to indoor conditions and to the corresponding outdoor concentrations, as well as the discovery of possible correlations between specific de...

BACKGROUND Psychological stress appears to contribute to poor oral health systemically in combination with other chronic diseases. Few studies directly examine this relationship. METHODS Data from a cross-sectional study of 2,412 participants between the ages of 25-64 years old living in the City of Toronto between 2009 and 2012 were used to examine the relationship between current stress and...

Abstract Objectives The prevalence of recurrent aphthous stomatitis (RAS) among the general population worldwide is 20%. This study aims to discover any correlations between RAS predisposing factors and gender year undergraduate dental students at Faculty Dental Medicine Airlangga University. Methods A cross-sectional analytical using simple random sampling was performed. respondents answered s...
