A Stereo Microscopic Evaluation of Microleakage - Laser Versus Visible Light Cured ClaSS V Composite Resin Restorations - An Invitro Study.

Composite resins are the most commonly used direct restorative materials in present day practice. Argon laser has been approved for photo polymerization of light Sensitive restorative materials. In this study a Comparative evaluation was made to assess the Marginal sealing ability of Visible light cured and argon laser cured class V Composite resin restorations. Occlusal and cervical areas were compared in degree of marginal leakage by giving separate scores for both the areas. Marginal leakage was higher in cervical margin than the occlusal margin in both the groups. A higher degree of marginal leakage was observed in laser cured restorations compared to the visible light cured restoration.
