title: Microleakage evaluation using acetate peel technique.
abstract: OBJECTIVE
  To evaluate and measure the interfacial space or the restoration cavity integrity for probable microleakage using acetate film; acetate peel technique under different magnifications.
  
  
  METHODS
  Premolar tooth was obtained and standardized class V restoration with Z-350 done both buccally and lingually. The tooth was hemisectioned buccolingually and embedded in epoxy resin, polished, acid etched, washed and dried. The sectioned sample was flooded with acetone and a pre-cut acetate film placed over it. As the acetone evaporated, the film took the shape of the micro relief produced by etching and dried in 10-15 mins. It was pulled off the tooth surface and mounted between two glass slides for examination under research microscope with different magnifications.
  
  
  RESULTS
  This enabled us to measure the interfacial space that might lead to leakage of restoration and also could detect the intricate details of tooth.
  
  
  CONCLUSIONS
  The acetate peel technique is an efficient way to study the interfacial space/restoration-cavity marginal integrity at a higher magnification and was a fast and reliable tool for assessing the microleakage of a restorative material.
