The hydrophilic acrylic resin can cause denture-cleaning molecules to enter through microporosity which can be toxic to the oral tissue. Plant-based denture cleanser is commonly used one of which is edamame (Glycine Max L. Merrill) extract. Denture cleanser made from edamame extract needs to be tested for toxicity to determine the biocompatibility of the material in the oral cavity, specifically on fibroblast cells. This study aims to determine the toxicity of edamame extract as a denture cleanser for heat-cured acrylic resin, which is soaked for 4 days against BHK-21 fibroblast cells. This 4-day submersion equals 15 minutes of submersion per day for 1 year. The toxicity tests were carried out using the MTT assay method. The results of these MTT tests can be seen from the absorbance values and calculating the percentages of cell viability. The more cells that are still alive, the more intense the purple color produced. The research results showed that the acrylic resin group which was soaked in a 50% concentration of edamame extract was not toxic to fibroblast cells, because the percentage of cell viability had a value of >70%, which was 83.638%. This research concludes that 50% concentration of edamame extract as a denture cleanser for heat-cured acrylic resin is not toxic to BHK-21 fibroblast cells compared to 75% and 100% concentrations of edamame extract.","PeriodicalId":23739,"journal":{"name":"World Journal of Advanced Research and Reviews","volume":"12 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141795930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different versions of Emergency Remote Education (ERE) emerged, in which theoretical classes were taught remotely to the detriment of practice, which would be taught at another time. The discipline of Anatomy, as it is based on practice, suffered a great impact on its modus operandi leading to adaptations. Practical classes were temporarily suspended to be taught in a subsequent period, dissociated from theoretical teaching, and carried out remotely online. Methodology: 254 medical students from a public university were interviewed. All students had taken at least one period of Anatomy at ERE and at least one period in person. Results: The majority of students did not agree with the usefulness of remote classes, but they participated in online tutoring and did not seem to believe that remote teaching could lead to insecurity in the application of anatomy in the clinic. Conclusion: In general, the student did not fully approve of the ERE, but did not feel disadvantaged in the teaching of Anatomy, and prefers face-to-face teaching.","PeriodicalId":23739,"journal":{"name":"World Journal of Advanced Research and Reviews","volume":"5 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141796191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
