Postoperative Sensitivity In Class V Composite Restorations: Comparing Soft Start Vs. Constant Curing Modes Of Led., Fahad Umer, Frahan Raza Khan
Department of Surgery
Background: One of the major disadvantages associated with using composites is polymerization shrinkage, stresses are generated at the margins, and if these stresses exceed the bond strength, microleakage occurs at the tooth restoration interface which causes ingress of cariogenic bacteria, post-operative sensitivity, and secondary caries. LED offers several curing modes: constant cure, ramped cure, and soft start cure. It is claimed that soft start polymerization mode produces less polymerization shrinkage and consequently less postoperative sensitivity. Objective:To compare the postoperative sensitivity in Class V composite restorations using soft start and constant LED curing modes. Materials and
Methods:
Using the appropriate …
