Low-Level Laser Adjunctive Use with Orthodontic Treatment of Patients with Compromised Periodontal Structure
Background: The analgesic and inflammatory-modulating effects of low-level laser in adjunct to orthodontic treatment for patients with compromised periodontium was assessed.
Materials & Method: A randomized controlled clinical trial through split-mouth design was done for 20 patients with chronic periodontitis underwent orthodontic treatment. One side of dental arch received Laser application (Test group), while the other side received pseudo-laser treatment (Control group). Laser application was repeated twice / week for 4 weeks following orthodontic treatment initiation and monthly thereafter until treatment termination. Subjective pain was assessed by visual analogue scale (VAS); clinical periodontal condition was assessed with periodontal parameters (GI, PI, PPD, and GR). GCF levels of IL-1β, and PGE2 were measured by ELISA.
Results: Pain intensity was markedly decreased on Laser- treated side at the all follow-up visits; with a lower peak value during first week following orthodontic treatment initiation (P ≤ 0.05). The PI scores were slightly increased on both sides, but with fewer levels on Laser-treated side at 1-month, whilst GI scores were decreased by the third-month follow -up (P ≤ 0.05). A marked decreased level of IL-1β and PGE2 in GCF was noted during the 1st month of the orthodontic treatment initiation (P≤0.05).
Conclusion: In view of these results, it can be postulated that LLL application exhibits beneficial value in pain relief and inflammation control, during early stage of orthodontic treatment among patients with compromised periodontium.
Keywords: LLL application, VAS, pain associated with initial application of orthodontic appliances.
