COVID-19, caused by SARS Cov2 virus is a global pandemic and a threat to the world population and economy. It can manifest with a broad spectrum of clinical symptoms ranging from asymptomatic cases to pneumonia or even fatality. One of the treatments suggested is convalescent plasma therapy. The study aims at assessing the general awareness about Covid-19 and knowledge about the role of Convalescent plasma therapy for treatment of -19 among post graduate dental students. The survey was conducted among postgraduate dental students through an online survey tool using google forms. The survey was conducted online among postgraduate dental students on the go with 19 and convalescent plasma therapy. total of 103 participant were included in the study. The responses were collected, tabulated and using SPSS software. The knowledge regarding -19 and the awareness about the usefulness of convalescent plasma was variable. Around 90% of the participants were aware of the effectiveness of convalescent plasma therapy. Advance training, proper PPE and training on handling the patients with any infectious disease should be dealt with in detail for reducing the spread from dental clinics and dentists.

Background: Recurrent aphthous stomatitis (RAS) is a chronic ulcerative disease with a complex aetiology and a strong immunological basis. The prototypical pro-inflammatory cytokine is interleukin-1 (IL-1). IL-1alpha and IL-1beta are the two subtypes of IL-1. The proinflammatory cytokine interleukin-1beta is a key mediator of inflammation which affects cell proliferation and differentiation. Aim: To systematically review the association of Interleukin 1 beta with the recurrent aphthous stomatitis. Methods: A comprehensive search was done using electronic data bases such as PubMed Central, Google Scholar and direct web search. The title scan was used to find relevant articles, which were then read and appraised for inclusion. This review analysed all research that investigated the use of IL1 beta with RAS. Results: Electronic database search identified 31 articles. After evaluating the title, abstract, and full text of these articles, only 2 were selected for the present systematic review. A final of 2 studies were included based on the inclusion criteria to meet the research question. Conclusion: This current study shows that IL1 beta is not a significant reliable indication of RAS. The association of IL1 beta and RAS varies due to a variety of confounding variables.

This study will help in determining which molecules participate in the ulceration with an integrated approach combining external and internal factors. Recurrent aphthous stomatitis (RAS) is a common condition affecting the oral mucosa. Clinically it is manifested through recurrent painful lesions. A total of 28 subjects were recruited for this systematic case-controlled study (14 Control and 14). Whole unstimulated saliva was used for measuring Cortisol and IL-1 b levels. Patients with RAS lesions exhibited an elevated salivary cortisol level as against their healthy counterparts. The mean value for salivary cortisol among RAS patients was determined to be 16.2 nM/dL as against the control group which had a mean salivary cortisol of 12 nM/dL. Overall, this study helps provide insights into the correlation of the different biomarkers and RAS patients which can eventually lead to better therapeutic options and prevent recurrence in patients.

Background: Xylene is an aromatic hydrocarbon that's extensively used as a deparaffinizing agent, and it's far extraordinarily biohazardous. It is proven to be the best chemical to be used in histopathological laboratories in spite of its carcinogenic potential. Aim: The aim of this study is to do a systematic review on the efficacy of cedarwood oil as clearing agent and deparaffinizing agent alternative to xylene in histopathological laboratories. Materials and Methods: The articles for this review were searched from PubMed, Google Scholar, Google search and manual search using the keywords cedarwood oil, natural substitute, natural alternative and xylene. The final of 3 articles were included in the review which compared the efficacy of cedarwood oil as a natural alternative with the gold standard xylene. Once the articles to be reviewed were finalized, data was collected, tabulated and was verified and interpreted. Results: Three articles included in this review showed considerable and acceptable results with cedarwood oil as clearing and deparaffinizing agent. Conclusion: Merits and demerits are equally found in both the reagents but compromising the time and cost in terms of cedarwood oil for health benefits hold good for the pathologists but bad for the patients. In case of xylene, compromising the health benefits of workers which results in quicker diagnosis hold good for the patients but not for the pathologists. Finally storage and disposal of these two reagents still remains questionable.
