Knowledge, attitude, practice on different matrix systems used for class 2 composite restorations among dental students

Introduction: A matrix is defined as a properly contoured piece of metal or other contoured piece of metal or other material used to support and give form to material used to support and give form to the restoration during its placement and restoration during its placement and hardening. Characteristics of a good matrix are rigidity, establishment of proper anatomical contour,restoration of correct proximal contact relation, easy adaptation to the tooth, easy adaptation to the tooth,ability to be contoured,prevention of gingival excess, strength to offer resistance to condensation pressure and easy removal from the tooth. Aim: To check the knowledge and practice of different matrix systems in class 2 composite restoration. Materials and Methods: Self administrated questionnaire was designed based on matrix systems for class 2 composite restoration. The questionnaire was distributed through an online survey link. The questionnaire was completed by 100 participants, and the data were analysed using SPSS software. Descriptive statistics and Pearson Chi square test were done to analyze the results of the survey. Majority of the participants are aware of the different matrix system for class 2 composite restoration.
