Evaluation of sealing ability of root end filling materials-an in vitro study

Surinder Kaur., Anuradha Pathak., Rajinder Singh and Rattan Lal Jain

Aims:  The  aim  of  the  present  study  was  to  compare  and  evaluate  the  sealing  ability  of different root  end  filling  materials  by   testing  their  microleakage.
Methods and Material:  One hundred and   fifty   extracted human single rooted anterior teeth were resected  at  an  angle  of  0 0   and  an  apical  cavity  of  2 mm  depth  was  made  in  each  root. All  the  specimens  were  divided  into  five  groups  of  30  each.  The roots were then decalcified  by using  clearing  technique.
Stastistical  analysis  used:  The  stastitical  analysis  was  perfomed  by  using  stereomicroscope  at  10X  magnification  to  measure  dye  penetration  from  the  surface  of  the  filling  upto   deepest  portion of  penetration.
Results:  Statistical  differences  (P<0.0010)  were  seen  among  all  the  groups  in  the  descending  
order  amalgam  (Septalloy),  glass  ionomer  cement  (ChemFlex),  cermet  cement  (Hidense),  
compomer (Dyract)  and  mineral  trioxide  aggregate  (Pro Root MTA).
Conclusions:  Mineral  trioxide  aggregate  provided  best sealing  ability  as  compared  to  the  other  
Groups.  Sealing ability of the   compomer was better than glass ionomer cement.  Amalgam exhibited maximum microleakage as   compared to the other groups.
