Abstract :A thermal assisted light polymerization method for enhancing the degree of conversion of resin composite and reducing viscosity thus improving marginal adaptation of the restoration is to preheat the composite resin before placement. Heating the composite also dramatically decreases the curing time required for light polymerization. With the added benefit of greater depth of cure of the restorative composite, increased chemical conversion, and ease of flow for easier dispensing into the cavity preparation, pre-heating or sometimes called as pre-warming has become an indispensable technique for better dentistry. In spite of all these advantages, the cost and availability of device is a limiting factor in its use which can be overcome by using this simpler device commonly available in all clinics to make this technique popular and economically viable. A new, simple and innovative technique for pre-heating/pre-warming of dental composite resins in thermal assisted light polymerization technique is presented.
