Abstract
Background:A furcation perforation is mid-curvature opening into periodontal ligament space which is a worst possible outcome in root canal treatment. Perforations should immediately be repaired with a biocompatible material to seal the communication between perforation site and gingival sulcus.Aim:The aim of this study was to evaluate the push-out bond strength of glass ionomer cement, hydroxyapatite, mineral trioxide aggregate, and biodentine (BD) when used in repairing furcal perforations with and without blood contamination in permanent molars.Materials and Methods:A total of 120 human extracted molars were collected and divided on the basis of perforation repair materials and blood contamination status (n = 15). All the materials were subjected to universal testing machine to a load cell from 0 N to 100 KN at a crosshead speed of 1 mm/min.Statistical Analysis:The data obtained were subjected to statistical analysis using SPSS version 20.0. Results andConclusion:The push-out bond strength was maximum in BD contaminated with blood and least for the hydroxyapatite contaminated with blood. A significant difference was found between all the perforation repair materials.
