Temperature changes caused by light curing units on dentine of primary teeth.

AIM: This was to determine the temperature changes produced in dentine discs of primary teeth placed below a glass ionomer, microhybrid flow resin or microhybrid resin during the photocuring process with conventional halogen lamps and LEDs at different distances.

STUDY DESIGN: Experimental design.

MATERIALS AND METHODS: This in vitro study was carried out in the research laboratory of the Universitat International de Catalunya. We cut 1 mm thick dentine discs with the IsoMet 1000 cutting machine. Thereafter, we cut stainless steel rings of different heights. Subsequently, to facilitate the temperature measurement, we prepared silicone moulds, in which the dentine disc, stainless steel ring and the digital thermometer/ thermocouple were positioned. Once the silicone mould was finished, a 2 mm thick layer of the restorative material was placed on the dentine disc. Finally, the polymerisation process was conducted according to the times recommended by the manufacturers, and the temperature produced was recorded at the end of the procedure. STATISTICAL EVALUATION: Replies were analyzed using the STATGRAPHICS® Plus Version 5.0 statistics software system, in order to obtain comparative diagrams and graphs using the ANOVA multifactorial system.

RESULTS: The photocuring lamps used on the restorative materials produced statistically significant differences in temperature, with p = 0.00001.

CONCLUSION: Halogen lamps cause a greater temperature rise in materials than LEDs lamps, and the greatest rise is produced when microhybrid flow resin is photocured with the Optilux 501 halogen lamp.
