Abstract

<jats:title>Abstract</jats:title><jats:p>The aim of this <jats:italic>in vitro</jats:italic> study was to evaluate the antibacterial activity of calcium silicate repair cements and sealers against a dual‐species planktonic aerobic model with different aging times and the ability to inhibit the formation of a mature 21‐day‐old multispecies anaerobic biofilm. The antibacterial activity of ProRoot MTA, MTA Angelus, Biodentine, BioRoot RCS and TotalFill BC sealer against a dual‐species aerobic planktonic model, as well as measuring how materials were affected by aging, was evaluated using the Modified Direct Contact Test. Subsequently, the ability to inhibit the formation of a mature multispecies anaerobic biofilm was evaluated using scanning electron microscopy complemented with confocal laser scanning microscopy. Biodentine and BioRoot RCS had higher antibacterial action, and Biodentine was able to maintain its antibacterial action after a prolonged aging period <jats:italic>in vitro</jats:italic>. Calcium silicate repair cement MTA ProRoot and Biodentine had higher antibiofilm action.</jats:p>
