Development is a complex phenomenon where the forming phenotype interacts with genetic and environmental inputs. Teeth are an important model for developmental studies and their development has been thoroughly investigated. However, despite of an extensive literature on the genetics of dental development, no studies have yet focused on the environmental influences on dental morphology. Here we ...

This study compared the effectiveness of stress management programs in dental education by systematic review of the literature. The number of studies concerning stress management programs for dental students is limited compared with studies discussing sources of stress. Several types of programs for stress management have been reported, and differ in their duration, content, and outcomes. Two m...

AIM This study aimed to record, both subjectively and objectively the anxiety of patients awaiting placement of their first dental implant and their long term stress levels; and evaluate their relation to the perception of pain by the patient during and after the procedure. METHODOLOGY Early morning salivary cortisol samples were collected from 47 patients awaiting the placement of their firs...

The aim of this study was to investigate sources of stress and psychological disturbance in dental students across the five years of undergraduate study at a dental school in Trinidad. Eighty-three percent of students completed a modified version of the Dental Environment Stress questionnaire (DES) and the Brief Symptom Inventory (BSI). On a scale ranging from 0 (not stressful) to 5 (highly str...

The aim of this study was to analyze the stresses that develop by oblique and vertical forces in endodontically treated maxillary second premolars that were restored with resin composite. Additionally, in our study the effects of the different restorative approaches and use of different base materials on stress formation were analyzed using three-dimensional finite element stress analysis. For ...

Introduction: the Restoration of endodontically treated teeth is critical, and the Awareness of stresses developed by oblique and vertical forces in restorative methods take a great role in treatment plans. Due to the anatomical shape and inherent form of the stress distribution premolars, could be lost by fractures. Some fractures such as vertical fracture which is probable in...

The study was conducted to report on the scope and prevalence of occupational health related-problems experienced by dentists, dental therapists, and oral hygienists in their practice of dentistry. BACKGROUND Professional practice and dental training have many risk factors, and the dental team should be able to recognize these factors to protect themselves. The prevalence of conditions relate...
