Abstract

Aim

Avoiding temperature rise in the periodontal ligament during endodontic laser application is crucial. This study aims to validate the safety of a dual wavelength laser endodontic protocol on the periodontal ligament when cleaning and debriding curved root canals.

Methods

8 human curved root canals were prepared using the reciproc system and stored in thymol solution until the experiment was conducted. The samples were placed in a 37 °C water bath to mimic the body temperature. The dual wavelength laser (Er,Cr:YSGG, 2 W, 20 Hz, 50 μs, 80 Water, 30 Air and diode 940 nm 2 W, 50% duty cycle) was applied in each canal for one cycle. The thermal changes on the outer surface of the root were measured in the cervical, middle and apical thirds of the canal. The recorded measurements were descriptively analysed.

Results

None of the irradiated samples exhibited a temperature rise over 47 °C on the outer surface of the root canal. Contrarily, a temperature drop on the outer surface was recorded.

Conclusion

The dual wavelength laser Er,Cr:YSGG 2 W, 20 Hz, 50 μs, 80 Water, 30 Air and diode 940 nm, 2 W, 50% duty cycle is a safe tool to be used in debriding and cleaning curved root canals.
