Commercial “composite warmers” are available (e.g., Calset, AdDent Inc., Danbury, CT) to preheat the composite resin to preset temperatures up to 68°C (155°F). he increased temperature lowers the viscosity of the composite resin, potentially resulting in better marginal adaptation and reduced microleakage, although some of these results have been shown to be composite specific.Reference: Sturdevant Art and Science of Operative Dentistry 7th ed. p.235
