PopulationRCTs of patients with carious pulp exposure in one or more permanent teeth (reversible or irreversible pulpitis) treated with direct pulp capping, partial pulpotomy, or full pulpotomy21 RCTs (30 records) of patients with carious pulp exposure in permanent teeth; per-trial sample size 26-413 (median ~60)
InterventionAny biomaterial used to cap the exposed/amputated pulp (e.g., calcium hydroxide, MTA, Biodentine, CEM, PRF); interventions and comparators deliberately not distinguished (all retrieved agents treated as of interest)10 capping materials formed the network; MTA (20 trials) and calcium hydroxide (14) most studied, then Biodentine (5), Theracal (3), PRF (3), CEM (2); also TAP, Abscess Remedy, Acemannan, nano-hydroxyapatite
ComparisonAny other capping biomaterial (network of all available materials)Same 10-material network; only 31% of possible comparisons informed by >=1 trial
OutcomesPrimary: composite clinical and radiographic success at >=6 months. Secondary: continued root formation, tooth discoloration, dentin bridge formationPrimary success pooled only for CH vs MTA (OR 2.94, 95% CI 1.96-4.49; low certainty); secondary outcomes (root formation, discoloration, bridge formation) reported narratively without pooling
Study designsRandomized controlled trials (including split-mouth and cluster RCTs)21 RCTs (17 two-arm, 3 three-arm, 1 four-arm); includes 1 split-mouth and cluster RCTs; RoB 2 overall moderate
