Summary

The aim of this prospective, randomized clinical study is to compare the frequency and intensity of post-operative pain after root canal treatment with ultrasonically-activated or laser-activated irrigation.

Conditions

  • Post-operative Pain

Interventions

DEVICE

Laser-activated irrigation with a pulsed Er:YAG laser

The root canals and the pulp chamber are filled with NaOCl 3%. Per canal, the laser tip is placed above the root canal entrance and activated (frequency 20 Hz, pulse energy 20 mJ and pulse length 50 μs) for 30s. TThe canal is then rinsed with NaOCl using a 27G needle, followed by a second application of laser, identical to the first.

DEVICE

Ultrasonically activated irrigation

The root canals and the pulp chamber are filled with NaOCl 3%. An Irrisafe file, driven by an ultrasonic unit according to the manufacturers' instructions, is held at 1-3 mm from WL (precurved if canal is curved) and activated for 30 s. The canal is then rinsed with NaOCl using a 27G needle. This cycle is repeated three times (i.e. 3\*20s).

PROCEDURE

Orthograde root canal treatment

After rubber dam isolation and field disinfection, the pulp chamber is accessed. The root canal(s) is/are located and shaped using manual and mechanical NiTi instruments in combination with NaOCl (3%) irrigant. The canals are dried using paper points and obturated with gutta percha and epoxy resin sealer. The tooth is sealed with a temporary or permanent filling.
