The Impact of Restarting the High-Risk Procedures for COVID-19 Infection in Dental Practice on the Anxiety of Dental Employees: A Study with Repeated Measures.

Background: As SARS-CoV-2 is detected in the infected patients' saliva, dental employees performing aerosol-generating procedures are at high risk of being infected/spreading the infection.

Aims: This study aimed to assess the impact of restarting the high-risk procedures for COVID-19 infection in dental practice during the pandemic on the anxiety levels of dental employees.

Adaptive radiation therapy for cervical esophageal cancer: dosimetric and volumetric analysis.

Background: Cervical esophageal cancer (CEC) patients may suffer from significant anatomical changes due to tumor shrinkage or weight loss during radiotherapy. The aim of the study is to evaluate the volumetric and dosimetric changes in the target and critical volumes of CEC patients by using adaptive radiotherapy (ART) technique.

Methods: Seven CEC patients treated in helical tomotherapy (HT) unit was analyzed.

A heart atlas for breast radiation therapy and the influence of delination education on both intra and interobserver variability.

Purpose: We developed a heart atlas for breast radiation therapy and evaluated the influence of education on intra and inter-observer similarity, and cardiac dose reporting.

Materials And Methods: The data of 16 left breast cancer patients were analyzed. Eight observers delineated heart and cardiac subunits [left (LCA) and right (RCA) coronary arteries, left anterior descending artery (LAD), bilateral atrium and ventricles] before the education.
