Clinical Evaluation of Sectional Matrix Versus Circumferential Matrix for Reproduction of Proximal Contact

Clinical Evaluation of Sectional Matrix Versus Circumferential Matrix for Reproduction of Proximal Contact by Undergraduate Students and Postgraduate Dentists: Randomized Controlled Trial

The aim of this study is to evaluate the effects of different matricing techniques either sectional matrix or circumferential matrix on reproduction of optimum proximal contacts and contours during restoration of class II cavities with resin composite by undergraduate students or postgraduate dentists.
