Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Review question
| Element | Planned (methods) | Found (results) |
|---|---|---|
| Population | Healthy human adults (18 years or more) with dentine hypersensitivity from exposed root surfaces | 390 participants in six studies (subjective assessment based on 108 participants) |
| Intervention | Daily home use of potassium containing toothpaste | Potassium nitrate toothpaste 5% (n=390) |
| Comparison | Control toothpaste identical to the test paste but without the potassium salt | Control toothpaste without potassium nitrate (n=390) |
| Outcomes | Changes in (1) pain symptoms in response to tactile, thermal and airblast stimuli; (2) patients' subjective assessment of pain during every-day life; only studies reporting data suitable for meta-analysis (mean and SD) were included | Tactile assessment (method a) (n=1); Tactile assessment (method b) (n=5); Air blast assessment (n=6); Thermal assessment (n=1); Subjective assessment (n=3) |
| Study designs | Randomised controlled trials (RCTs) | RCT, parallel group (n=6) |
| Timing | Sensitivity measured at 6 to 8 weeks | 8 weeks (4 studies); 12 weeks (2 studies) |
