Temporomandibular disorder / jaw pain
LLLT wavelengths for temporomandibular disorder pain network meta-analysis
Ren H, Liu J, Liu Y, et al. Journal of Oral Rehabilitation. 2022.
A network meta-analysis compared LLLT wavelength ranges and TENS for TMD pain.
Evidence grade
moderate
Effect direction
positive
Panel relevance
partially-replicable
Key findings
- The review included 27 RCTs with 969 patients.
- All active treatment groups improved pain scores compared with placebo.
- The 910-1100 nm wavelength range ranked best for pain relief immediately after treatment and at one-month follow-up.
Protocol details
| Wavelengths | 633, 672, 780, 904, 910, 1100 nm |
|---|---|
| Irradiance | Not reported mW/cm2 |
| Fluence | Not reported J/cm2 |
| Session time | Not reported minutes |
| Frequency | Varied by trial |

Caveats
- Network rankings depend on indirect comparisons across heterogeneous trials.
- Most consumer panels do not target 910-1100 nm light.
