Photobiomodulation therapy (PBM) Therapy Showed Promising Decrease in Prevalence of Postoperative Endodontic Pain

A recent study reported, Photobiomodulation therapy (PBM) therapy after endodontic treatment showed a significant decrease in the prevalence of postoperative pain.

Luana Pontes Barros Lopes and colleagues conducted the randomized, controlled, clinical study with the aim to assess the effect of PBM with low-level laser irradiation (LLLI) on postoperative pain after endodontic treatment.

A total of 60 patients diagnosed with irreversible pulpitis in lower molar teeth were included in the investigation. A single operator performed all the therapies. The randomization was carried out and participants were divided into two groups: In experimental group (EG), endodontic treatment was presented with a reciprocating system, immediately followed by PBM with LLLI; and In the control group,  only endodontic therapy was performed. Postoperative pain was evaluated by a second examiner, who was blinded, using two scales: the verbal rating scale (VRS) and the numerical rating scale (NRS). The assessment was carried out at 6, 12, and 24 h after treatment. Data were analyzed using chi-square, Fisher's exact, Mann-Whitney tests, ordinal, and non-parametric regression analyses.

For the prevalence of pain, the difference between the groups was significant for the evaluations performed after 6 hours with p = 0.04 and at 24 hours, p = 0.02. The difference after 24 h remained significant after stratification. Increased pain intensity was linked to the extrusion of the root canal filling material to the periapical region in the two scales used.
