Abstract

Background: Bonding of sealer to root canal walls is likely to increase the integrity of the sealer-dentin interface during mechanical stresses, thus increasing resistance to fracture. Chitra-CPC sealer is an indigenously manufactured bioceramic material and has been used as bone graft and perforation repair material. When used as a sealer, it has good potential to reinforce the root strength in addition to excellent biocompatibility.

Aim: To compare the fracture resistance of teeth obturated with novel Calcium phosphate cement-based sealer viz. Chitra CPC with Endosequence BC sealer, MTA Fillapex and AH Plus

Methods and Material: The study was carried out in 100 single rooted extracted, decoronated mandibular premolars of length 11 mm. The teeth were randomly divided into 4 groups (n = 20 for each group). Other than Group 1A and group1B, all other groups were restored with various endodontic sealers and obturated with Gutta Percha. In group1A, the teeth were left unprepared and unfilled (negative control), in group 1B, the teeth were left unobturated (positive control) In group 2, Epoxy resin based sealer (AHPlus ) ;In group 3, mineral trioxide aggregate–based sealer (MTAFill apex); In group 4, Calcium phosphate cement based sealer (Chitra-CPC);in group 5,Bioceramic based sealer(Endosequence BC ) were used. After 2 weeks all specimens were tested for fracture resistance using Universal testing machine at a crosshead speed of 1.0 mm/min until the root fractured. The force required to fracture each specimen was recorded, and the data was analysed statistically.

Results: The fracture resistance values of Chitra –CPC and Endosequence BC sealer were significantly higher than that of positive control and comparable to negative control.

Conclusions: In contrast to MTA Fill apex and AH Plus, Chitra –CPC and Endosequence BC sealer increased the fracture resistance of teeth.
