Abstract

For the complete disinfection of canals intra canal medicaments like calcium hydroxide and triple antibiotic paste are used in necrotic open apex roots in which apexification is to done by either MTA or Biodentin. Therefore, the aim of this study was to evaluate the effect on push-out bond strength of MTA and Biodentine by calcium hydroxide and triple antibiotic paste residues. One hundred fifty maxillary central incisor teeth with simulated open apices were divided into 4 experimental groups and a control group. Groups are divided as Group 1A as CH with Biodentin, Group 1B as TAP with Biodentin, Group 2A as CH with MTA, Group 2B as TAP with MTA and Group C as control group without any medicament and with both Biodentin and MTA. Push-out bond strength was evaluated for all samples using a universal testing machine and bond failure by steromicroscope. The bond strength was calculated in MPa and bond failure as cohesive, adhesive or mixed. Mean values and SD for push‑out bond strength test were calculated and statistically analysed using one‑way analysis of variance. P values less than or equal to 0.05 were considered to be statistically significant. Comparison of results  showed that control group was significantly higher bond strength than both experimental groups, implying that both intra canal medicament residues negatively affect the bond strength of both Biodentin and MTA(p<0.05).Intra group comparisons show that there is no statistically significant difference between the bond strength deterioration caused by CH or TAP.
