Conservative restoration of pulpless premolars with composite resins is indicated in specific instances. The effect of parapulpal pins on marginal leakage and fracture resistance was evaluated in this in vitro study for composite resin restorations in 80 extracted, pulpless premolars. Conservatively prepared pulpless premolars restored with composite resin were resistant to occlusal forces and parapulpal pins were effective in reducing gingival marginal microleakage. Parapulpal pins significantly improved the marginal seal of composite resin restorations in pulpless teeth when the gingival margins of the restoration were placed in dentin.
