Objective study via randomized controlled trial design, the effect of irrigation activation via either diode laser or ultrasonic on the post-operative pain, in single visit endodontic treatment of necrotic single canal teeth. 

Materials and Methods Forty four single canal anterior and premolar teeth with necrotic pulps were equally and randomly allocated to two different final NaOCl irrigation activation protocols. The patients were randomly allocated to either diode laser activated irrigation (Group A) or ultrasonic activated irrigation (Group B). Group A used the 320 nm flexible plain endodontic fibre of 970nm diode laser device. Group B used ultrasonic file (U-file) #15 in ultrasonic device for activation. Single visit endodontic treatment was done and post-operative pain was recorded after 24, 48, 72 hr and 1 week using a numerical rating scale (NRS). Data were analyzed using Chi–Square, Mann–Whitney and Friedman tests. A p-value ≤ 0.05 was considered statistically significant.

Results Comparing the two groups; After 24, 48 and 72 hours pain score range was 0-2 with no statistically significant difference. Over the tested time intervals; in Group A: laser; there was no statistically significant difference in median NRS score (p=0.065). While in Group B: ultrasonic; there was statistically significant increase in median NRS scores comparing preoperative with 24 hr. (p=0.001). 

Conclusion The 970nm diode laser and ultrasonic activated irrigation proved to be equally effective in achieving low incidence and intensity of post-operative pain after single visit endodontic treatment of necrotic single canal teeth.
