Question · asked by 1 review
Dental cavity liner (e.g. calcium hydroxide, glass ionomer, resin-modified glass ionomer, or flowable composite) placed under the restoration vs No cavity liner or a different liner material: Treatment failure
- Population
- Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis
- Intervention
- Dental cavity liner (e.g. calcium hydroxide, glass ionomer, resin-modified glass ionomer, or flowable composite) placed under the restoration
- Comparison
- No cavity liner or a different liner material
- Outcome
- Treatment failure
The evidence is very uncertain about the effect of cavity liners on treatment failure; no significant difference between lined and unlined (or differently lined) restorations was found (very low certainty).

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.
