Introduction: In the past10 to 15 years, operative dentistry has been improved to be as needed as possible, with a new development away from GV Black’s ‘extension for prevention’ to the up-to-date minimum intervention concepts, due to understanding of the carious process, the advances of adhesive aesthetic materials and a gratitude of the consequences of the removal of hard tooth structure. There was a huge expansion of resin composite dentistry over the last few decades. During the placement of resin restorations, the resin is polymerized direct in situ. As a consequence of polymerization, resin composite is accompanied by shrinkage. Shrinkage will be directed the stresses to the along restoration interfaces. Materials and methods: A questionnaire will be modified. The questionnaire is designed to elicit information from dental students regarding their knowledge about the matrix band placement. The target population from 4th year-6th year dental students. Results: The majority of the participants were female (61.3%, n=245). The distribution of the participants by year and University. Almost all the participants (99.0%, n=396) practice restorations for class II cavity. In class II cavities, the majority prefer composite restorative material, use tofflemire matrix band (82.8%, n=372), and place a wedge while doing restorations (95.8%, n=383). Conclusion: Amongst dental students and intern in Saudi Arabia, 95% of them practiced on composite class II restoration. They preferred to use matrix band “tofflemire” for restoration. Almost, all of them using wedges and polish of restoration. Also, most of them take 10 to 20 minutes to prepare the class II cavity preparation. Failure of restorations is common, and the commonest failure is Open margin restoration.
Key words: Class II composite restorations, tofflemire retainer, dental students, failure, overhang.
