Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Proximal Contact Device: MD ring and precontoured sectional matrix by TOR VM Device: Circumferential matrix and tofflemire retainer by Kerr Not Applicable

Estimated Study Completion Date : January 15, 2020

Arm Intervention/treatment
Experimental: Sectional matrix
precontoured sectional matrix band
Device: MD ring and precontoured sectional matrix by TOR VM
MD ring (separation ring) and precontoured sectional matrix (thickness 0.035mm hard) and a diamond wedge was used to secure matrix in place

Active Comparator: Circumferential matrix
Circumferential matrix band applied by tofflemire retainer
Device: Circumferential matrix and tofflemire retainer by Kerr
Circumferential matrix (thickness 0.038mm) applied by tofflemire retainer and secured in place with diamond wedge




Primary Outcome Measures :
  1. Proximal contact [ Time Frame: Up to 3 hours from randomization till contact is restored ]
    Reproduction of proximal contact either optimum, tight or loose (Categorical)
