title: Comparison of sealing ability of ProRoot MTA, RetroMTA, and Biodentine as furcation repair materials: An ultraviolet spectrophotometric analysis.
abstract: OBJECTIVE
  To evaluate the sealing ability of ProRooT MTA, RetroMTA, and Biodentine as furcation repair materials using dye extraction leakage method.
  
  
  METHODS
  Thirty-five mandibular molars were randomly divided into four groups according to the material used for perforation repair. Group I - ProRoot MTA (10 samples), Group II - RetroMTA (10 samples), Group III - Biodentine (10 samples), and Group IV (Control) - left unrepaired (5 samples). All samples were subjected to orthograde and retrograde Methylene blue dye challenge followed by dye extraction with concentration 65% nitric acid. Samples were then analyzed using ultraviolet-visible spectrophotometer using 550 nm wave lengths.
  
  
  METHODS
  One-way analysis of variance, Tukey-Kramer multiple comparisons test.
  
  
  RESULTS
  Biodentine showed least dye absorbance while RetroMTA showed highest dye absorbance values when compared with other repair materials.
  
  
  CONCLUSIONS
  Within the limitations of this study, it was observed that Biodentine showed better sealing ability when compared with other root repair materials.
