NCT05421182
At the "Métropole Savoie" hospital, to deal with the daily influx of severe patients during the second wave of COVID-19, 23 patients had to be transferred away from their home city and far from their families as part of a medical evacuation (EVASAN). The purpose of the study is to investigate whether there is an association between medical evacuations and the occurrence of psychological disorders such as post-traumatic stress, anxiety or depression occurring within 6 to 10 months in families of evacuated patients. The investigators want to compare the prevalence of psychological disorders in the families of patients evacuated for a serious form of COVID-19 (cases) compared to that of families of patients not evacuated (controls) hospitalized for a serious form of COVID-19.

Introduction: Green dentistry, is high-technology approach that reduces the environmental impact of dental practices, improper disposal of dental materials wastes results in environmental hazards. Aim of the study: This studied will be performed o evaluate the effect of repressing of three different types of pressable ceramics, Ips Emax press, Lisi press and Celtra press with different weight percentages on patient satisfaction, mechanical properties, microstructural features and composition of these pressable ceramics. Materials \& Methods: Seventy five ( N=75) pressable ceramic discs will be constructed ,The samples will be divided to three groups (n=25 each) according to types and composition of pressed and repressed ceramics .Group 1: IPS Emax press .Group 2: Gc Lisipress Group 3: Celtrapress . Each group willbe divided into 5 sub-groups (n=5) according to the weight percentage of newly pressed and repressed ceramics. Subgroup A: 100% new ceramics. Subgroup B: 75% new and 25 % repressed ceramic .Subgroup C: 50% new and 50% repressed ceramics. Subgroup D:25%new and 75% repressed ceramics. Subgroup E: 100% repressed ceramics. Biaxial flexural strength will be measured using universal testing machine. X-ray diffraction will be performed to identify the crystalline phases, and a scanning electron microscope will be used to describe microstructural features. Energy dispersive X-ray analysis will be used to evaluate change in composition Also surface hardness will be evaluated. Patient satisfaction, plaque, cervical caries and marginal discoloration will be evaluated in a follow- up of one year (in vivo part).
