Objectives: The objective of the study were to determine if there was any (bisphenol A) BPA release from three adhesive brands, to determine the differences of BPA release between three adhesive brands, to determine the genotoxicity from three adhesive brands, and to determine the correlation of BPA release and genotoxicity. Methods: Three branded adhesives materials were polimerized in mold and immersed in pH 7 and 4 artificial saliva from 24 to 720 hours. The artificial saliva was tested with spectrophotometry test to see BPA release at 24, 240, 480, and 720 hours, then freeze dried to get solid extract. Combination of the extract and lymphocite culture (male and female) then tested with in vitro cytokinesis-block micronucleus (MN) assay to see genotoxicity level of three adhesives at 24, 240, 480, and 720 hours as well. Results: The BPA release occured at 720 hours by Adhesive 1: 0.013μg/L; Adhesive 2: 0.11μg/L; Adhesive 3: 0.036μg/L. There was a statistically significant difference between BPA release with time (F = 505.98; p=0.00) and brands (F = 147.65; p = 0.00). Time and BPA release interaction also showed a statistically significant difference (F=13.35; p=0.00). Genotoxicity can be seen at 720 hours on Flowtain LV sample (MN frequency: male: 0.044; female: 0.053). Conclusion: The number of BPA release of all brand can be seen from the first 24 hours, and were increasing from 24 to 720 hours. Genotoxicity can be seen from one of the adhesive brand at 720 hours.There was correlation between BPA leaching and micronucleus frequency

Abstract: The main transmission medium of Covid-19 is aerosol from nose and oral cavity when coughing, sneezing, and speaking. Due to the vast transmission of the virus, the Indonesian government has established various health protocols to reduce the impact of the disease. Until now, the high number of confirmed COVID-19 patients in Jakarta is suspected as a result of lack of knowledge and perception. This study was aimed to determine the relationship between knowledge, perception, and attitudes of COVID-19 transmission in dentistry in JABODETABEK Jakarta. This was an analytical and observational study with a cross-sectional design using online questionnaire containing 50 questions. This study was conducted on 572 subjects. The validity of the questionnaire was analyzed by using the Rasch model and the linear regression between variables and mediation analysis. The results obtained that the questionnaire showed a Cronbach alpha of 0.82 and item reliability of 1.00 with a separation of 29.97. Most subjects were in high category of knowledge (97.20%), perception (60.66%), and attitudes (93.88%). There was a relationship between knowledge and perception (p<0.001; 95%CI 0.357-0.925); perception and attitude (p<0.001; 95%CI 0.643-0.829); and the perception as a mediator between both variables. In conclusion, JABODETABEK communityâ€™s perception of COVID-19 transmission has an impact as mediator or influence peopleâ€™s attitude in implementing their knowledge in dentistry.Keywords: knowledge; perception; attitude; COVID-19Â Abstrak: SARS-CoV-2 merupakan tipe coronavirus baru yang dapat menimbulkan penyakit COVID-19.

Objectives: The growing popularity of vaping has introduced additional challenges, as potential health risks are still under investigation. Exploring differences in smoking perceptions between smokers and non-smokers could provide valuable insights into smoking behavior and inform effective intervention strategies. This study aimed to evaluate and compare the perceptions of smoking, specifically vaping and conventional cigarette use, among young adult smokers and non-smokers. Methods: An analytical cross-sectional design was employed, with 542 university students included through random sampling, using a questionnaire consisting of 8 items. Data were analyzed using the Kruskal-Wallis test and Rasch model analysis. Results: Of the subjects, 259 (48%) used vapes and 283 (52%) were non-smokers. The age distribution was as follows: under 19 years (13.51% vs 38.87%), 19-20 years (46.33% vs 32.16%), and over 21 years (40.15% vs 28.98%). The Wright map indicated perceptual differences between smokers and non-smokers, with smokers showing greater agreement with smoking perceptions (>1 logit). Significant differences (p < 0.001) were found in each item across all groups. Conclusion: The study identified distinct perceptual differences regarding smoking between smokers and non-smokers, with smokers having a more favorable perception towards smoking. Non-smokers generally showed a stronger aversion to conventional cigarettes compared to electronic ones. These findings underscore the importance of developing targeted smoking cessation programs that address the specific perceptions and attitudes of both groups.

Introduction: Academic potential test (APT) is the terminology used for requirement in student recruitment process at Faculty of Dentistry, Trisakti University. According to literature, APT score is believed to predict the academic achievement in graduate school. Objectives: This study assessed the impact of APT score on GPA score at Bachelor Dental Program year 2015-2018. Methods: Cross sectional descriptive analysis were done on 486 students, divided into 4 groups based on credit semester (CS); group A 144 CS, B 100 CS, C 60 CS, and D 20 CS. Result: mean APT score were 598 + 95.46 and GPA score were 2.63 + 0.72. Linear regression test showed significant correlation between APT and GPA scores (p=0.007; r2=1.5%). It shows that APT contributed as only a little aspect for the success of students in their study. In dentistry, there are other factors that may influence GPA score beside APT such as intellectual quality, talent, behavior, psychomotor and capability in social, science and communication. Conclusion: Academic potential test could be used to predict the GPA score in Bachelor Dental Program.
