Implication

In vitro study evaluates temperature changes in resin composites, indicating factors influencing pulpal risk.

Key Points

This study evaluates how different types of resin composites, increment thickness, and light intensity affect temperature rise during photopolymerization.
In vitro experimental study with a factorial design
Temperature measured at the center of increments using a type K thermocouple
Four-way ANOVA was used to analyze data, with α = 0.05
Temperature increase ranged from 3.24 °C to 18.18 °C across groups (p < 0.05)
Flowable composites led to the highest temperature rise (p < 0.001)
4.0 mm increments produced greater increases than 2.0 mm (p = 0.008)
