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 | Immature (young) permanent teeth with open apex and vital pulp exposed to dental caries or trauma (in humans) | Immature permanent teeth with carious or traumatic pulp exposure in children aged 6-14 years (5 RCTs; 232 teeth and 118 roots) |
| Intervention | Pulpotomy dressing agents (e.g., MTA, calcium hydroxide, CEM, PRF, triple antibiotic paste) | MTA (index agent in all 5 trials); comparators CH, CEM, PRF, TAP and abscess remedy |
| Comparison | A different pulpotomy dressing agent (RCTs comparing two or more medicaments) | MTA vs CH (2 trials); MTA vs CEM, MTA vs PRF, and MTA vs TAP vs abscess remedy (1 trial each) |
| Outcomes | Clinical and/or radiographic success rate | Clinical and radiographic success rate |
| Study designs | Randomized controlled trials (RCTs) | 5 RCTs (4 parallel, 1 split-mouth); all judged high risk of bias |
| Timing | At least 6 months follow-up | 6 to 24 months follow-up |
