COMPARATIVE EVALUATION OF SEALING ABILITY OF PROROOT MTA, BIODENTINE AND BONE CEMENT IN THE REPAIR OF FURCATION PERFORATION - AN IN VITRO STUDY ABSTRACT

Abstract

ABSTRACT

Context: Furcal perforation is a common occurrence during endodontic treatment. Prompt intervention and use of proper repair materials is very important to improve the prognosis of involved tooth. Material qualities are also determining factor of success. Search for newer materials that are easy to manipulate, cost effective with better physical and biological properties is a never ending process.

Objective: The aim of this in vitro study is to evaluate the sealing ability of ProRoot MTA, Biodentine & Bone cement as furcation repair materials in molar teeth using dye penetration method analysed under the stereomicroscope.

Materials and Methods: Forty five recently extracted mandibular molars with non-fused well-developed roots were collected and intentional furcation perforations were made with a bur and perforations were treated with ProRoot MTA, Biodentine and Bone Cement. These specimens were then immersed in Rhodamine B dye. After their removal, Dye penetration was evaluated after longitudinal sectioning of the teeth under the stereomicroscope.

Results: Results showed that furcation perforation repaired with Biodentine showed decrease in microleakage compared with that of ProRoot MTA and Bone Cement. However, there was no statistically significant difference between the ProRoot MTA and Biodentine.

Conclusion: Biodentine is a promising material for furcation repair as it overcomes some of the disadvantages of ProRoot MTA like long setting time and poor handling characteristics.
