Aim:
The purpose of this study was to compare the sealing ability of the three light-cured temporary restorative materials curing with two different light curing devices; halogen and LED.
Methods:
After the preparation of standard endodontic access cavities, the canal systems were instrumented by using a step-back technique irrigated with sodium hypochlorite and EDTA. Light-cured temporary restorative materials; First fill, Bioplic, and Diatemp were applied and polymerized with either of the LED or Halogen light-curing devices. The specimens were immersed in 2% methylene blue solution for four days in an incubator for the leakage assessment.
Results:
The first fill presented the least microleakage values for both the LED (2.54±0.53) and halogen (2.84±0.48) treated groups whereas; Diatemp presented the highest microleakage values for both the LED (2.83±0.59) and halogen (3.28±0.56) groups. The leakage values of all light-cured temporary filling materials for the LED-treated groups were lower than the halogen treated ones. However, there were statistically no significant differences among the three groups (P>0.05).
Conclusion:
It is concluded that light curing temporary filling materials can achieve a good and comparable sealing capacity when cured by both LED and halogen LCUs.
