The root canals were obturated in the same session using cold lateral compaction technique with AH Plus sealer (Dentsply DeTrey, Konstanz, Germany), Protaper Universal gutta-percha (ProTaper Universal gutta-percha, Dentsply) and .02 tapered auxiliary gutta-percha (Diadent, Chongju, Korea) cones. Residual gutta-perchas in the access cavity were removed with the aid of heated hand tools. The quality of root canal filling was checked with periapical radiographs. The pulp chamber was filled with flowable composite resin (Filtek Ultimate Flowable, 3M-ESPE, St. Paul, MN, USA) and nanohybrid composite resin (3M-ESPE) using an incremental technique. Intraoral cryotherapy was not applied.

Root canals were filled with calcium hydroxide paste (Kalsin, Turkey), prepared according to the rate recommended by the manufacturer using a lentulo spiral (Dentsply Sirona, Switzerland) 2 mm from the working length. Sterile dry cotton pellets were placed in the pulp chamber, then the access cavity was sealed with a temporary filling material and occlusion was checked. Intraoral cryotherapy was not applied. Patients were given an appointment 7 days later for second visit. In this appointment, patients were anesthetized, the tooth was isolated with rubber dam, the temporary filling material was removed. Then calcium hydroxide paste was removed by using the last instrument used to prepare the root canals at the working length during the first appointment using sufficient irrigation. The final irrigation protocol was repeated. Root canal fillings and permanent restorations were completed by applying the same techniques as in single session groups.
