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

Tooth survival · Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis

Cavity liners may make little or no difference to tooth survival (99.4% survival across groups; low certainty).
