Comparative Efficacy of Conventional Versus Diode Laser Assisted Root Canal Treatment in Reduction of Postoperative Pain and Healing of Periapical Lesion: A Randomized Controlled Clinical Trial.

BACKGROUND

Laser assisted root canal treatment has emerged as a promising adjunct to conventional randomized controlled trials (RCTs).

MATERIAL AND METHOD

To evaluate the same, we observed 90 patients (98 roots) with chronic periapical lesions; they were randomized into two groups ( = 45): diode laser and control. The level of pain was measured before and at 6, 12, 24, 48, and 72 hours after treatment using a visual analog scale. Cone beam computed tomography images were obtained before and 6 months after treatment to assess the healing of periapical lesions based on their apicocoronal, mesiodistal, and buccolingual diameters.

RESULT AND CONCLUSION

It was observed that root canal disinfection by diode laser significantly decreased the postendodontic pain and resulted in a higher success rate in lesion resolution.
