ABSTRACT
Dental students learn from home during the COVID-19 pandemic era. Knowledge of dental materials will affect the success of the dental practice. Adequate polymerization of the composite resin knowledge needs for good clinical performance. This study aims to determine the level of knowledge of dental students about adequate polymerization of composite resins at the Faculty of Dentistry, Universitas Trisakti, during the COVID-19 pandemic era. In this descriptive observational study with a cross-sectional approach. A total of 100 dental student respondents filled out a questionnaire. Four-teen questionnaires are about Light Curing Units (LCU), composite resin components, material application, irradiation procedure, and inadequate polymerization. The correct answers were categorized into three levels of knowledge: 76–100% good, 56–75% sufficient, and < 56% less. The results showed that the knowledge level of the respondents was good (23%), sufficient (43%), and less (34%). Most of the respondents had good knowledge of LCU type, composite resin application, irradiation procedure, and inadequate polymerization effect. Although the respondent need to improve the knowledge about composite resin components. The limitations of the COVID-19 pan-demic era caused dental students to need to increase their knowledge by independently exploring dental materials literature. This knowledge will support skills in clinical practice on patients.
