Biodentine vs Calcium hydroxide (CH)

Overall success (composite of clinical and radiographic success) · Vital permanent teeth (mature or immature) with deep or extremely deep caries and asymptomatic pulp or reversible pulpitis, undergoing…

Biodentine and calcium hydroxide did not differ significantly in clinical and radiographic success (OR 3.14, 95% CI 0.91 to 10.86; ungraded subgroup analysis).

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

Secondary prevention of caries · 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 secondary caries prevention (~100% prevention across groups; low certainty).

Hydraulic calcium silicate cements (HCSC; MTA or Biodentine) vs Calcium hydroxide (CH)

Overall success (composite of clinical and radiographic success) · Vital permanent teeth (mature or immature) with deep or extremely deep caries and asymptomatic pulp or reversible pulpitis, undergoing…

At 36-month follow-up, HCSC show higher odds of clinical and radiographic success than CaOH (OR 2.34, 95% CI 1.43 to 3.84; ungraded subgroup).

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

Restoration longevity · 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 restoration longevity (high success across groups; low certainty).

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

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).

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

Postoperative hypersensitivity (POH), patient-reported (VAS score) · Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis

The evidence is very uncertain whether cavity liners reduce postoperative hypersensitivity; no significant difference was found overall (very low certainty).

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).

Oral health-related quality of life · Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis

No included study reported oral health-related quality of life (a planned outcome), so no evidence is available.
