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).

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).

Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years
Composite resin (hybrid 0-19.5%; bulk-fill 0-16.9%) performed comparably to or better than most alternatives across 11 RCTs; evidence is of low to unclear quality (ungraded).

Not applicable (no eligible studies) · Children with carious primary teeth (no pulp therapy)
No eligible RCTs assessed new bio-active restorative materials in carious primary teeth; this is an evidence gap identified by the review.

Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years
Glass carbomer had very high failure rates (up to 46.2%) in a single RCT, far worse than composite resin or RMGIC; low quality of evidence (ungraded).
