Abstract
BACKGROUND
To evaluate the effect of EDTA, Maleic acid, Citric acid and MTAD Irrigating Solutions on the shear bond Strength of A-H plus sealer.
MATERIALS & METHODS
Forty mandibular single rooted premolar teeth with straight roots were taken, decoronated and instrumented using Protaper rotary instruments to size #F3, 0.09 taper, at the working length, with 3 mL of 2.6% sodium hypochlorite in between irrigation. The teeth were divided into 4 groups and final irrigation was done using NaOCl/EDTA:Group 1(Positive Control group); NaOCl/Maleic acid: Group2; NaOCl/Citric acid: Group 3; NaOCl/MTAD: Group 4. Obturation was done using Obtura II thermoplasticized technique with AH Plus sealer. Each root section was then subjected to a compressive load via a universal testing machine, to measure the push out bond strength.
RESULTS
The data was collected and submitted to statistical analysis by One way ANOVA test, and Group 2: NaOCl/Maleic acid showed greater bond strength (6.542+/_ 1.12 MPa) than other groups.
CONCLUSION
Removal of smear layer with Maleic acid as a final rinse enhanced the adhesive ability of A-H plus sealer, followed by EDTA, Citric acid and MTAD. A final rinse with MTAD might have a negative effect on the bonding ability of resin-based A-H plus sealer.
