title: [The effects of the enameloplasty on the penetration and adaptation of sealant].
abstract: OBJECTIVE
  To study the mechanism of enameloplasty technique by observing penetration and adaptation of sealant.
  
  
  METHODS
  60 extracted molars were selected and divided into three groups: pits and fissures of the samples in group A were prepared with bur(EST); those in group B were cleaned with cup-shaped brush(CST); group C, as control.
  
  
  RESULTS
  The penetration of EST was (83.75 +/- 13.11)%, CST was (55.30 +/- 11.98)%. The presence of defects between sealants and inclines of cusp of EST and CST were 7.32% and 19.05% respectively, and between sealants and lateral walls of fissures were 16.07% and 38.93%.
  
  
  CONCLUSIONS
  The penetration and adaptation of EST was superior to CST.
