Preformed crowns for decayed primary molar teeth 2015 · Cochrane All outcomesSix months and four years
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…

Adverse effects (tooth staining and other side effects) · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)
