A Comparative Evaluation of the Effect of Photobiomodulation on the Depth of Anaesthesia During Endodontic Treatment of Teeth with Symptomatic Irreversible Pulpitis-A Prospective Clinical Trial.

Background: Effective pulpal anesthesia is crucial in endodontic practice, particularly in treating symptomatic irreversible pulpitis. This study explores photobiomodulation therapy (PBMT) as a non-invasive adjunct to traditional anesthesia.

Aim: To compare the efficiency of diode laser and Er, Cr: YSGG laser in enhancing anesthesia depth during endodontic treatment of teeth with symptomatic irreversible pulpitis.

Methods: A total of 45 patients were divided into three groups: placebo (Group 1), diode laser (Group 2), and Er, Cr: YSGG laser (Group 3). Visual Analog Scale (VAS) scores were recorded at three stages: pre-operative, during access opening, and post-operative.

Results: Both laser groups demonstrated significantly lower VAS scores compared to the placebo group. The diode laser showed the most significant reduction in pain during the procedure.

Conclusion: Photobiomodulation using diode and Er, Cr: YSGG lasers effectively enhances anesthesia depth during endodontic treatment, with diode laser showing superior results.
