[Evaluation of BioPure MTAD as an endodontic irrigant on the apical sealing ability of AH Plus sealer in vitro].
OBJECTIVE
To evaluate whether BioPure MTAD could affect the apical sealing ability of AH Plus sealer in vitro.


METHODS
Forty-four extracted single-rooted human teeth were randomly divided into six groups. The canals were treated with distilled water,1.3%NaClO,5.25 %NaClO+17%EDTA,1.3%NaClO+BioPure MTAD and 1.3%NaClO+3%EDTA endodontic irrigants, respectively. After obturated, the teeth were made transparent and permitted dye penetration,then measured by using a stereoscopic microscope. SPSS 12.0 software package was used for One-way ANOVA.


RESULTS
The microleakages lengths of obturated root canals in group C,D,E,F were (1.81+/-0.73)mm, (0.53+/-0.49)mm, (0.40+/-0.44)mm and (0.39+/-0.55)mm, respectively.Group C had significantly more leakage than group D,E,F(P<0.05), but there were no significant differences among group D,E,F(P>0.05).


CONCLUSIONS
Compared with other endodontic irrigants which usually used in clinic, BioPure MTAD doesn't adversely affect the apical sealing ability of AH plus sealer.
