The produced β-TCP was calculated as a weight ratio (wt%) and 5%, 10%, and 20% were added, and then specimens for various mechanical evaluation, bioactivity, and cytotoxicity evaluation were produced. \u0000Results: As β-TCP content increased, setting time increased. And, compressive strength and Vickers hardness increased. In addition, seven days after putting it in the SBF solution, apatite was observed on the surface. \u0000Conclusions: Therefore, these results suggest that amount of β-TCP in polycarboxylate cement increased, mechanical properties improved and bioactivity increased.","PeriodicalId":232441,"journal":{"name":"The Korean Society of Oral Health Science","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133341168","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}

It then analyzed the factors affecting their levels of anxiety regarding exposure. \u0000Results: The results showed statistically significant differences between anxiety relating to dental radiation exposure and knowledge of radiation (-0.252, p < 0.01) and perceptions of radiation (-0.582, p < 0.01). An examination of the factors affecting the anxiety of dental patients regarding exposure to radiation showed that a high recognition of the need for dental radiography (p < 0.05) and more negative perceptions of radiation (p < 0.001) resulted in greater anxiety regarding radiation exposure (p < 0.001). \u0000Conclusions: In order to reduce anxiety about radiation exposure, educational materials should be produced and patient education conducted so patients can have correct knowledge and perceptions of dental radiation. In addition, relevant regulations or legal guidelines should be prepared so that radiation safety education for patients can be practiced systematically.","PeriodicalId":232441,"journal":{"name":"The Korean Society of Oral Health Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129681669","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}
