Objectives.
The aim of this in vitro study was to assess thermal changes on tooth tissues during light exposure using two different LED curing units.
The hypothesis was that no temperature increase could be detected within the dental pulp during polymerization irrespective of the use of a composite resin or a light-curing unit.
Methods.
Caries-free human first molars were selected, pulp residues were removed after root resection, and four calibrated type-J thermocouples were positioned.
Two LED lamps were tested; temperature measurements were made on intact teeth and on the same tooth during curing of composite restorations.
The data was analyzed by one-way analysis of variance (ANOVA), Wilcoxon test, Kruskal-Wallis test, and Pearson’s χ2.
After ANOVA, the Bonferroni multiple comparison test was performed.
Results.
Polymerization data analysis showed that in the pulp chamber temperature increase was higher than that without resin.
Starlight PRO, in the same condition of Valo lamp, showed a lower temperature increase in pre- and intrapolymerization.
A control group (without composite resin) was evaluated.
Significance.
Temperature increase during resin curing is a function of the rate of polymerization, due to the exothermic polymerization reaction, the energy from the light unit, and time of exposure.
