Randomly distributed or "fluctuating" dental asymmetry has been accorded evolutionary meaning and interpreted as a result of environmental stress. However, except for congenital malformation syndromes, the determinants of human crown size asymmetry are still equivocal. Both a computer simulated sampling experiment using a combined sample size of N = 3000, and the requirements of adequate statis...

The aims of this study were to identify the perceived sources of stress in final-year dental students studying in a private dental school in Riyadh, Saudi Arabia, using a modified dental environmental stress (DES) scale and to correlate these findings, at various times in the semester, with the level of acute stress measured with salivary cortisol as a biomarker. A total of forty final-year stu...

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...

Teeth are central for the study of ecology, as teeth are at the direct interface between an organism and its environment. Recent years have witnessed a rapid growth in the use of teeth to understand a broad range of topics in living and fossil primate biology. This in part reflects new techniques for assessing ways in which teeth respond to, and interact with, an organism's environment. Long-te...

Dental caries remains a significant public health problem and is considered pandemic worldwide. The prediction of dental caries based on profiling of microbial species involved in disease and equally important, the identification of species conferring dental health has proven more difficult than anticipated due to high interpersonal and geographical variability of dental plaque microbiota. We h...

BACKGROUND Dental schools are known to be highly demanding and stressful learning environments. Dentistry involves an acquisition of required academic, clinical and interpersonal skills during the course of learning. Practicing dentistry requires clinical skills and patient management skills, which also add to the stress perceived by the students. Identifying sources of stress represents the cr...

The complete genome sequence of Streptococcus mutans, a bacterial pathogen commonly associated with human dental caries, was published in 2002. The streamlined genome (2.03 Mb) revealed an organism that is well adapted to its obligately host-associated existence in multispecies biofilms on tooth surfaces: a dynamic environment that undergoes rapid and substantial fluctuations. However, S. mutan...

objective: dental profession is associated with a high level of stress experienced by clinicians in private practice as well as students and instructors in dental school environment. the purpose of this study was to detect the main stressors in dental students of school of dentistry, babol university of medical sciences in 2011-2012.   methods: in this descriptive, analytical study, data were c...

objectives: this study sought to assess the effects of length and inclination of implants on stress distribution in an implant and terminal abutment teeth in an implant assisted-removable partial denture (rpd) using three-dimensional (3d) finite element analysis (fea).   materials and methods: in this in vitro study, a 3d finite element model of a partially dentate mandible with a distal extens...

Objectives The purpose of this study was to identify the major sources of perceived stress and their relation to a student satisfaction questionnaire about the curriculum and the pedagogy among French dental students. Materials and Methods All dental students (n = 178) from years 4 to 6 at the University of Montpellier (France) participated in this exploratory survey. In spring 2016, a 3-part...
