(PR74) Penetration of two bioceramic sealers into lateral canals of straight canals obturated with a single-cone gutta percha technique

AH Plus Bioceramic (Dentsply Sirona, USA) has met the ISO 6876 standard for flowability. NeoSEALER Flo (Avalon Biomed, USA) is a new high flow bioceramic sealer. No previous studies have assessed the flowability of NeoSEALER Flo. In this study 3-D printed models were developed with straight root canals and lateral canals for evaluation of sealer penetration following obturation. The models were used to compare the penetration of AH Plus Bioceramic sealer (Dentsply Sirona, USA) and NeoSEALER Flo (Avalon Biomed, USA) into lateral canals of straight canals obturated with a single gutta-percha cone. -D split models with simulated straight, and lateral canals (diameter 0.2mm, depth 5.0mm) positioned bilaterally at 1 mm, 3 mm, 5 mm, and 7 mm from apex were designed (#30/.04, 23.0mm length) and printed from resin polymer (Autodesk, San Rafael, CA). Canals (straight, n=50) were obturated with either AH Plus Bioceramic (n=25) or NeoSEALER Flo (n=25) and a single cone gutta-percha. The level of sealer penetration into lateral canals was measured using ImageJ. The depth of penetration of the sealer was not significantly different (p < 0.05) between the two bioceramic sealers at 3 mm, 5 mm and 7 mm. Sealer penetration into apically positioned lateral canals (1 mm) was significantly less (p < 0.05) than at other levels. Sealer penetration into simulated lateral canals was similar between AH Plus Bioceramic and NeoSEALER Flo. Sealer penetration was less in the apically positioned lateral canals.
