Safety culture regards the perceptions, beliefs, abilities and safe behavior of individuals or groups of people with respect to their activities, especially work, to achieve a level of Occupational Health and Safety (OHS) performance. This study aims to determine the factors related to the work safety culture of the University of Hasanuddin laboratory employees. This study employs quantitative research using a cross-sectional design involving 73 participants from 64 laboratories of 10 faculties at the Hasanuddin University. The research instrument was adapted from Edgar Schein’s theory and the PRISM FGI Safety Culture Application Guide. The questionnaire used was adapted from the Loughborough Safety Climate Assessment Toolkit (LSCAT). Data analysis was done using the Spearman’s correlation test and the regression model residual test. The results show that management commitment, communication, safety rules and procedures, social environment support, involvement, safety as a priority and need, and personal appreciation for risks are significant (all p-value <0.05) in determining safety. In particular, social environment support, involvement, and safety as priorities and needs are the factors that determine the work safety culture of Hasanuddin University laboratory employees. Work Safety Culture Regression Model = 21.012 + 0.652 Social Environment Support – 0.274 Engagement + 1.616 Safety as Priority and Necessity. The most influential factor for the safety culture of university laboratory employees is the safety as priority and necessity. The work environment of each laboratory should be regulated according to ISO17025, for laboratory employees are more active in every activity related to OHS, especially for the activities of OHS laboratory.

ABSTRACT

Objective: The aim of this research was to determine the microleakage of apical sealer based on epoxy resin and methacrylate resin with continuous wave obturation technique. Material and Methods: Thirty permanent lateral incisors were selected randomly and divided into 3 groups. The samples were decoronated, the root canal was prepared and then the samples were kept in incubator at 37°C for 72 hours. The sample were coated with nail varnish then immersed in methylene blue for 48 hours. The samples were washed with distilledwater, dried and nailvarnish was removed. The samples were clearing and the penetration was measured using microscope and given score 0-4. Measurements were analyzed statistically using Kruskal-Wallistest and MannWhitney test. Results: There was no significant difference between the apical microleakage of the the epoxy resin-based root canal sealer with methacrylate resin-based root canal sealer (p>0.05). It means that the apical microleakage of the epoxy resin-based root canal sealer is comparable with methacrylate resin-based root canal sealer. Conclusion: It is concluded that the apical microleakage of epoxy resin-based sealer does not differ from the methacrylate resin-based sealer. Keywords
