Purpose
To determine if management with neodymium-doped yttrium aluminum garnet (Nd:YAG) laser therapy as an adjunct to scaling and root planing (SRP) yields a better periodontal outcome in terms of reduction in periodontal probing depth (PPD) and interleukin 1-beta (IL-1β) level, as compared to SRP alone for the treatment of periodontitis.
Methods
Searches were conducted on various online databases up to and including October 2018. Studies in which Nd:YAG laser therapy was used for the treatment of periodontitis were scrutinized procedurally, and studies fulfilling the inclusion criteria were retrieved and encompassed in the present study.
Result
Five studies were included in this analysis, which used the combined approach of Nd:YAG laser therapy + SRP (test group) and SRP only (control group). The follow-up period ranged from 8 to 12 weeks. The Nd:YAG laser used in all of the studies had wavelengths, energy/pulse, and duration of irradiation of 1064 nm, 75–100 mJ, and 60–120 s, respectively. Meta-analysis showed significant PPD reduction (Q value = 75.4, DF = 3, P value < 0.0001, I2 = 96.02%) and IL-1β reduction (Q value = 86.2, DF = 3, P value < 0.0001, I2 = 96.52%) for the test group as compared to the control group at follow-up.
Conclusion
It is still debatable and yet to be determined, whether Nd:YAG laser therapy + SRP yields better result when compared to SRP alone in reducing PPD and IL-1β level for treatment of periodontitis, given that there is lack of research related to it.
