Abstract
The purpose of this study was to compare and evaluate in vivo bacterial leakage after obturation of the tooth root canal with Apexit and Pulp Canal Sealer pastes. Thirty-two extracted human teeth were included in this research. The biomechanical processing was done with the crown-down technique and 2% NaOCl and 17% EDTA were used as irrig- ants. After instrumentation, the tooth roots were divided into two experimental groups: 16 teeth of the first group were obturated with the Apexit endodontic paste and 16 teeth of the second group were obturated with the En- doRez endodontic paste. After the obturation of the root canal, the teeth were stored in the Class II Safety Cabinet, Meti SAFE (Lamsystems, Berlin, Germany) for 7 days. For the determination of the leakage, the two-hole method was used and the duration of the research was 33 days. The average time of appearance of leakage in Pulp Canal Sealer was 5.3 days, while in Apexit it was 1.0 days. In the Pulp Canal Sealer group, turbidity appeared in 37.5% of cases, while in the group obturated with Apexit in 6.3% of cases. From our data, it can be concluded that Apexit paste is a better root canal obturation agent compared to Pulp Canal Sealer.
