Dentin hypersensitivity
Laser therapy for dentin hypersensitivity systematic review and meta-analysis
Pion LA, Matos LLM, Gimenez T, et al. Dental and Medical Problems. 2023.
A systematic review found laser therapy can reduce dentin hypersensitivity pain, but could not define one protocol.
Evidence grade
low
Effect direction
positive
Panel relevance
not-panel-replicable
Key findings
- Thirty-four studies were included; 11 entered quantitative analysis.
- Both high- and low-power lasers reduced pain after treatment in meta-analysis.
- Evaluation methods differed too much to establish a defined treatment protocol.
Protocol details
| Wavelengths | Not reported nm |
|---|---|
| Irradiance | Not reported mW/cm2 |
| Fluence | Not reported J/cm2 |
| Session time | Not reported minutes |
| Frequency | Dental protocol-specific |
| Duration | Many studies followed patients for up to 6 months |
| Treatment area | Sensitive teeth/dentin surfaces |
| Device type | Dental laser therapy |
Caveats
- Protocol heterogeneity is high.
- Dental diagnosis is needed because tooth sensitivity has multiple causes.
