Spatial Abilities and Endodontic Access Cavity Preparation: Implications for Dental Education.

Introduction: Access cavity preparation is a crucial step in root canal treatment but is one of the most complex procedures in the curriculum to learn, with students often reporting spatial orientation difficulties during drilling. The present study aimed to evaluate the influence of spatial abilities on the preparation of endodontic access cavities among third-year dental students.

Selenium Discrepancies in Fetal Bovine Serum: Impact on Cellular Selenoprotein Expression.

Selenium is an essential trace element in our diet, crucial for the composition of human selenoproteins, which include 25 genes such as glutathione peroxidases and thioredoxin reductases. The regulation of the selenoproteome primarily hinges on the bioavailability of selenium, either from dietary sources or cell culture media. This selenium-dependent control follows a specific hierarchy, with "housekeeping" selenoproteins maintaining constant expression while "stress-regulated" counterparts respond to selenium level fluctuations.

Personal risk factors and types of sport associated with drive for thinness and drive for muscularity in NextGen athletes.

Introduction: Professional and student-athletes are at risk of developing symptoms of eating disorders (ED), including drive for thinness and muscularity due to personal risk factors (e.g., low self-esteem) and sport-specific characteristics (e.

Oral Health of Rural Cameroonian Children: A Pilot Study in Bamendou.

Access to dental care in Cameroon is a public health issue, particularly for children living in rural areas. Given the lack of recent data, the investigation of children's oral health along with their oral hygiene behavior, needs in terms of care, and access to oral hygiene materials were investigated.
