title: Comparison of sealing ability of bioactive bone cement, mineral trioxide aggregate and Super EBA as furcation repair materials: A dye extraction study.
abstract: BACKGROUND
  Sealing ability of furcation repair material.
  
  
  OBJECTIVE
  To evaluate the sealing ability of bioactive bone cement, mineral trioxide aggregate (MTA) and Super Ethoxybenzoic Acid (EBA) as furcation repair materials in mandibular molars using a dye extraction leakage model.
  
  
  METHODS
  In vitro, dye extraction study.
  
  
  METHODS
  FORTY MANDIBULAR MOLARS WERE RANDOMLY DIVIDED ACCORDING TO THE MATERIAL USED TO REPAIR PERFORATION: Group I-MTA, Group II-bioactive bone cement, Group III-Super EBA, Group IV-Control (furcation left unrepaired). All samples were subject to ortho grade and retrograde methylene blue dye challenge followed by dye extraction with 65% nitric acid. Samples were then analyzed using Ultra violet (UV) Visible Spectrophotometer.
  
  
  METHODS
  One way analysis of variance (ANOVA), Tukey-Kramer Multiple Comparisons Test.
  
  
  RESULTS
  MTA and bioactive bone cement showed almost similar and lower absorbance values in comparison to Super EBA.
  
  
  CONCLUSIONS
  Bioactive bone cement provi ded an excellent seal for furcal perforation repair and at the same time it provided comfortable handling properties, which could overcome the potential disadvantages as faced with MTA.
