Influenza and corona viruses generate vaccine preventable diseases and have pandemic potential, frequently dramatic. A co-infection with these viruses, may be a new worldwide threat, researchers name ...it flurona. The aim of our study is to assess flu and COVID-19 Romanian vaccination for 2022-2023 season and the factor associated with higher odds to receive flu and COVID-19 vaccine.
An analytical cross-sectional observational survey was conducted in the general population; a self-administered questionnaire was used.
1056 responders were analyzed, mean age 32.08 ±13.36 years (limits:18-76), majority, 880 (83.33%), from urban areas, 608 (57.58%), high school graduated, 400 (37.88%) parents. More than half of the responders were healthcare workers, 582 (55.11%), also considered study population. In the study group, 796 (73.37%) responders consider flurona vaccination useful; and 872 (82.57%) responders consider that no sanctions are needed for not flurona vaccinating. In the 2022-2023 season, 162 (15.34%) responders vaccinated against the flu and 300 (28.41%) against COVID-19. The factor associated with higher odds to receive flu and COVID-19 vaccine was the habit of flu vaccination: for flu (OR = 58.43; 95% CI: (34.95-97.67)) and for COVID-19 (OR = 1.67; 95% CI: (1.21-2.31)). Other factors such as having university degree (OR = 1.46; 95% CI: (1.08-1.98)) and being a healthcare worker, (OR = 1.41; 95% CI: (1.07-1.87)) were influencing factors only for adult COVID-19 vaccination in the 2022-2023 season. In the parents' group, in 2022-2023 season, only 48 (12%) vaccinated their children against the flu and 68 (17%) against COVID-19, mostly parents that vaccinated themselves, p<0.001. In the 2022-2023 season, there were only 82 (7.65%) responders vaccinated against both diseases. Logistic regression analysis showed that no factor analyzed influenced the flurona vaccinated parent's decision to vaccinate their children for flu and for COVID-19.
In the season 2022-2023, in Romania, the vaccination against flu and COVOD-19 is low, in adults and children as well. More efforts must be done to increase flurona vaccination, public health educational programs are strongly needed. Children, that are at greater risk when co-infecting with these viruses, must be vaccinated, school vaccination programs should be considered.
The introduction of CAD/CAM technology in dentistry opened the way for the use of numerous materials for prosthetic restorations: dental alloys, ceramic masses, zirconia, PMMA, etc. One of the ...materials suitable for CAD/CAM technology is zirconia, used either ceramic-plated or full-contour, through its mechanical and optical properties. Zirconia, proves to be a real competitor for dental alloys used in porcelain fused to metal technology, with great results on posterior and frontal areas of dental arches. Prosthetic restorations made of zirconia in transit areas (including canines and premolars) exemplify the perfect combination between mechanical resistance and aesthetics of this material.
In dental practice, the fidelity of a model is given by the quality and type of material used, the technique by which it is made, and last but not least by the experience and skill of the dental ...technician. But, the emergence of CAD-CAM technology has led to a major change in the stages of making the working model, through the development of the virtual model. Thus, the purpose of this material is to perform a comparative study between several techniques for obtaining sectional working models, with or without pins, compared to the virtual model obtained by CAD-CAM technique.
Dental veneers made of ceramic masses are considered on conservative solution for patients that require an enhancement of shape, shade, dimension and/or position of anterior teeth. Ceramic veneers ...are successfully used on large scale to hide tooth discoloration, to correct the position and minor defects of teeth, without removing significant quantities of hard tissues.
Introduction. Titanium and the alloys that contain this element became in the last decade of the twentieth century almost irreplaceable materials in many biomedical fields, including dentistry. ...Purpose. The purpose of this study is to test and evaluate the cyto- and genotoxicity of Ti4 and Ti-6Al-4V, to obtain biomaterials with antimicrobial properties, compatible with the human body. Material and method. Ti4 and Ti-4Al-6V in powder form were analyzed using cell proliferation analysis and micronucleus test. Two concentrations of 1.5 mg/ml and 3 mg/ml were tested for each type of sample. Results and discussions. For both materials tested in the two concentrations, the presence of micronuclei was observed, but within normal limits. Conclusions. Although the variations are within normal limits, it should be noted that for Ti-6Al-4V the incidence was higher at both concentrations than in the case of Ti4.
Introduction. An important role in the appearance of acute or chronic infections is played by bacterial biofilms that contain several bacterial species and that develop preferentially on inert ...surfaces, dead tissues and medical devices. Purpose. In this material we tried to make an interesting study, regarding the adhesion capacity of microbial biofilms characteristic of the oral cavity of human subjects on the surface of materials used for industrial scale manufacturing of dental implants: titanium and zirconium dioxide (Zirconia). Material and methods. For this study were used plates of Ti4 and zirconia, on which adhesion of different bacterial strains belonging to the species Enterobacter cloacae, Klebsiella oxytoca and Klebsiella pneumonia were tested. Results and discussions. A rather high microbial load was observed on both types of materials for all types of bacterial strains studied. For certain types of strains, a lower colonization was noted in the case of zirconium dioxide compared to Ti4 surfaces. Conclusions. Although Zirconia has been reported to have a lower susceptibility to bacterial adhesion, our study contradicts this aspect specified in the literature. Both titanium and zirconium dioxide are promptly colonized by existing bacteria on the teeth left in the oral cavity
The Resistance was a reaffirmation of France's independence and individuality, as well as a struggle to regain freedom and, above all, national integrity. In fact, many historians appreciate that the ...French Resistance could have achieved more if it had been more effectively integrated into Allied plans and strategies. Thus, in this material we tried to present some short biographies of dentists who worked in the French Resistance against the German occupation troops, some of them even paying with their lives for the courage they showed.
Introduction. Atherosclerosis represents the process of stiffening of the arterial wall and includes arterial changes secondary to atherosclerosis, as well as physiological changes, reducing vascular ...elasticity in the elderly. However, the importance of knowing the pathology of atherosclerosis is mandatory among dentists, given the high frequency of patients with atherosclerotic lesions. Purpose. Through this study we tried to familiarize dentists on the therapeutic behavior towards patients with atherosclerosis but also the risks arising from it. Material and method. 87 practitioners from Romania helped to carry out this study between September and November 2018. Results and discussions. A clear picture emerged regarding the changes and manifestations in patients with atherosclerosis by dental practitioners as well as the attitude to be adopted in the case of treatments for such patients. Conclusions. Knowing the pathology of patients at cardiovascular risk as well as the therapy to be applied for them, is a must for dentists given the growing number of patients and the pathology with different stages of evolution.
