Class-I (single-surface) cavity restoration vs Class-II (proximal/multi-surface) cavity restoration

Treatment failure (annual failure rate) by cavity class · Children with carious primary teeth restored in Class-I versus Class-II cavities, no pulp therapy

Class-II restorations failed more than Class-I (annual failure 5-28.9% vs 1.2-14.7% in ART studies); low quality of evidence (ungraded).

Metal-free single crowns (full-contour zirconia) vs Composite strip crown

Treatment failure (annual failure rate) · Children (aged 3-5.5 years) with early childhood caries in anterior primary teeth (>=2 carious surfaces), no pulp therapy

Zirconia crowns failed less than composite strip crowns (3.3% vs 15% annual failure) in one RCT; low quality of evidence (ungraded).

Hall technique vs Compomer restoration or non-restorative caries treatment

Treatment failure (annual failure rate) · Children (aged 3-8 years) with 2-surface occluso-proximal dentine caries in primary molars, no pulp therapy

Preformed metal (Hall) crowns had a low reported annual failure rate (3.1%) versus compomer (14.7%) in one RCT; low quality of evidence (ungraded).
