Abstract

Objective: Clinical successful use of resin-based composite restorations (RBCs) depends on knowledge of
polymerisation related factors. The purpose of this study was to evaluate the knowledge of polymerisation of resin based composite.
Introduction: Resin-based composite (RBC) goes from a plastic phase to a semisolid phase through a process called
polymerization. The start of this process involves reactions that produce free radicals. These free radicals can be the result of energy
(heat or light) or chemical activation. Materials and methods: A questionnaire consisting of 10 multiple choice questions was
prepared based on the methods of polymerisation using online software. This study was conducted online which included 103
participants who were the undergraduates doing dentistry. The data were collected and analyzed through SPSS software.
Conclusion: The study suggests that undergraduates knowledge on polymerisation of resin base composite restorations is good.
