Caries distribution (individual/tooth/surface level) · European adolescents aged 12–19 years
Caries distribution was skewed at individual, tooth and surface levels and too heterogeneous to meta-analyze (narrative synthesis of 11 studies; not GRADE-rated).
1 finding from 1 review
No meta-analysis possible; caries distribution reported narratively from 11 studies as skewed at individual, tooth and surface levels, changing with age at tooth and surface level (Results – Caries distribution).

GRADE not reported
Early implant failure · Adults with missing teeth who received osseointegrated root-formed oral implants, functionally loaded and followed for at least 1 year
Turned (smoother) implant surfaces showed no clear difference in early implant failure compared with roughened implant surfaces (low certainty).

Peri-implantitis · Adults with missing teeth who received osseointegrated root-formed oral implants, functionally loaded and followed for at least 1 year
Turned (smoother) implant surfaces may leads to lower peri-implantitis compared with roughened implant surfaces (low certainty).

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).
