The push-out bond strength of different furcation perforation repair materials: A comparative study
Hashem, Ahmed Abdel Rahman / Marzouk, Abeer Mahmoud / El Far, Hebatallah Maged
Aim: The purpose of the present study was to assess the push-out bond strength of three furcation perforation repair materials: MTA, BioAggregate and IRM.
Materials and methods: Forty-five extracted human mandibular first molars were used in this study. Their roots were amputated 3 mm below the furcation and standardised access cavities were prepared in all molars. Furcation perforations of 1 mm diameter were performed between mesial and distal roots. The molars were divided into three groups (n = 15) according to the type of perforation repair material used. Group I was repaired with ProRoot MTA, group II was repaired with BioAggregate and group III was repaired with IRM. After setting, the samples were mounted in a loading fixture and each repair material was subjected, in an apical-coronal direction, to a compressive load with a load cell of 5 KN at a cross head speed of 1 mm/min with a 0.8 mm diameter plugger via a universal testing machine for the push-out bond strength measurement.
Results: There was no statistically significant difference between the push-out bond strength values of the three tested materials (P > 0.05).
Conclusions: It can be concluded that BioAggregate showed push-out bond strengths comparable to other commonly used root repair materials in small size cavities.
