Dental cavity liner (e.g. calcium hydroxide, glass ionomer, resin-modified glass ionomer, or flowable composite) placed under the restoration vs No liner (resin-based composite bonded directly to the tooth): Restoration failure
Dental cavity liner (e.g. calcium hydroxide, glass ionomer,… showed no clear difference in restoration failure compared with no liner (resin-based composite bonded directly to the tooth) (low certainty).

Studies behind the findings
None of these reviews ties its included studies to this outcome in the data here. Cochrane reviews and reviews with headline outcomes only do not list their studies yet.
How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
