title: "Evaluation of sealing ability of MM-MTA, Endosequence, and biodentine as furcation repair materials: UV spectrophotometric analysis".
abstract: OBJECTIVE
  To evaluate the sealing ability of MICRO-MEGA Mineral Trioxide Aggregate, Endosequence, Biodentine as furcation repair materials using a dye extraction leakage method.
  
  
  METHODS
  Forty mandibular molars were randomly divided according to the material used for perforation repair. Group I- (left unsealed) control, Group II-MICRO-MEGA Mineral Trioxide Aggregate, Group III - Endosequence, Group IV - Biodentine. All samples were subjected to orthograde and retrograde methylene blue dye challenge followed by dye extraction with 65% nitric acid. Samples were then analyzed using Ultra violet (UV) Visible Spectrophotometer.
  
  
  RESULTS
  Biodentine showed highest dye absorbance, whereas Endosequence showed lowest dye absorbance when compared with other repair materials.
  
  
  CONCLUSIONS
  Within the limitations of this study, it was observed that Endosequence showed better sealing ability when compared with other root repair materials.
