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

ElementPlanned (methods)Found (results)
PopulationHealthy human adults (18 years or more) with dentine hypersensitivity from exposed root surfaces390 participants in six studies (subjective assessment based on 108 participants)
InterventionDaily home use of potassium containing toothpastePotassium nitrate toothpaste 5% (n=390)
ComparisonControl toothpaste identical to the test paste but without the potassium saltControl toothpaste without potassium nitrate (n=390)
OutcomesChanges 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 includedTactile 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 designsRandomised controlled trials (RCTs)RCT, parallel group (n=6)
TimingSensitivity measured at 6 to 8 weeks8 weeks (4 studies); 12 weeks (2 studies)
