Influence of indirect air-cooling on the variation in intrapulpal temperature during rapid high-intensity light-curing using a bulk-fill resin composite.

Background: This study investigated the effect of indirect air-cooling on the variation in intrapulpal temperature (ΔT) during different light-curing protocols of bulk-fill resin composites in molars with class V cavities.

Material And Methods: A nonretentive class V cavity was prepared in a maxillary molar. The intrapulpal temperature changes with and without indirect air-cooling were recorded using a type K thermocouple.
