Table 2 Influence of air-cooling (AC), resin-based composite (RBC), volume of teeth (volume) and distance between the pulpal wall and the tip of the thermocouple (distance) on pulp chamber temperature increase according to generalized estimating equations. β coefficients, robust 95% confidence intervals andp values for AC effect are presented stratified by RBC, for RBC effect stratified by AC and pooled for volume and distance effect

From: How does indirect air-cooling influence pulp chamber temperature in different volume teeth and absence/presence of resin-based composite during light curing?
