:1. Introduction
2. Materials and Methods
2.1. Preparation of Plastic Tooth Samples
2.2. Obturation of the Plastic Tooth Samples
- Modified continuous wave technique group (CW, n = 12): The GP cone tip was coated with a small amount of AH Plus (Dentsply DeTrey) sealer at the apical 3 to 4 mm part and inserted into the canal. The GP cone was cut at 7 mm from the WL, using a fine sized heat plugger (#30, 0.04 taper) (SybronEndo, Orange, CA, USA) and System B (SybronEndo), packed with BL S-Kondenser (#35) (B & L Biotech, Ansan, Korea) at the 7 mm level and backfilled by using SuperEndo Beta 2 (tip size #25) (B & L Biotech) at a temperature setting of 200 °C.
- Single-cone technique group (SC, n = 11): CeraSeal (Meta Biomed, Cheongju, Korea) was snugly inserted in the canal space by using the provided needle tip; the tip was gently moved towards the orifice from the point from which it was engaged in. A GP cone was moved upward and downward three times to ensure good penetration of the sealer, cut using a fine-sized heat plugger and System B (SybronEndo), and gently packed with BL S-Kondenser (B & L Biotech) at the orifice level.
