Thermographic evaluation of three dental light curing units
Journal Title: Medicine in Evolution - Year 2018, Vol 0, Issue 3
Abstract
Aim and objectives. The aim of this study was to evaluate the potential of dental light curing units to induce irreversible changes to the dental pulp (secondary pulpitis). Material and methods. The study evaluated three dental light curing units: a LED unit, a plasma unit and a halogen unit. The experiments were performed using molars cut in halves. All the teeth had cavities that were filled with composite resin. Each procedure was visualized with the FLIR A40M thermographic camera. Results have shown that the temperature gradient for the floor cavity is the highest for the LED unit. The temperature in the dental pulp for the LED unit exceeded the 4 0C threshold known to bring irreversible damage to the proteins of the dental pulp tissues. Conclusion. The LED unit was the most harmful for the dental pulp.
