Effect of Diode Laser on Postoperative Pain after Endodontic Treatment with Two Different File Systems Involving Different Kinematics: An In Vivo Study
Year: 2025
Type: article
Abstract: Aim: To assess the diode lasers influence on pain after endodontic treatment with two different file system involving different kinematics. Materials and Methodology: A total of 160 teeth diagnosed with irreversible pulpitis were included in the study; patients were randomly allocated into four groups, each consisting of 40 teeth, for endodontic treatment. Two groups received laser treatment (one with continuous rotary instrumentation and the other with reciprocating motion), while the other two were control groups with similar instrumentation. Root canal instrumentation was done using ProTaper Gold or WaveOne Gold systems. Laser root canal disinfection was performed in the laser groups. Pain evaluation was conducted using a modified visual analogue scale at 6,12, 24, and 48 hours. Results: = 0.034) but did not maintain this effect at later intervals (12, 24, and 48 hours) compared with conventional treatment. There was no significant difference in pain scores between laser and control groups. Intragroup comparisons showed no significant difference in pain scores between continuous and reciprocating motion techniques. Overall, laser treatment may provide short-term pain relief but lacks lasting effectiveness compared with conventional techniques. The control groups experienced more pain than the laser groups. Conclusion: This study suggests that combining laser therapy with the WOG (reciprocal motion) system may reduce postendodontic pain.
