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.
Intervention categories, outcome domains and clusters are a proposed key pending human validation. Clear all filters

Preformed metal crown (stainless steel), conventional technique vs Aesthetic crown (stainless steel with composite/white veneer), conventional technique Adverse events: bone resorption · Children with decayed primary molar teeth · Six months and four years Preformed crowns for decayed primary molar teeth (2015) · Cochrane | Bone resorption: one case at six months in a tooth treated with a veneer crown; no bone resorption at either the veneer crown or stainless steel sites at four-year follow-up (Analysis 3.2). | 1 study · 11 participants | Very low |
Preformed metal crown (stainless steel), conventional technique vs Aesthetic crown (stainless steel with composite/white veneer), conventional technique Adverse events: gingival bleeding · Children with decayed primary molar teeth · Six months and four years Preformed crowns for decayed primary molar teeth (2015) · Cochrane | At six months, none (0/11) of the PMC sites had gingival bleeding, but all (11/11) veneer sites had bleeding, 10 of which bled on probing; statistically significant (McNemar's test, P < 0.001). At four years, one case… | 1 study · 11 participants | Very low |
