title: The Effect of Time of Post Space Preparation on the Seal and Adaptation of Resilon-Epiphany Se & Gutta-percha-AH Plus Sealer- An Sem Study.
abstract: BACKGROUND
  The field of endodontics is dynamic & ever expanding. With the availability of a wide array of products in the dental market it's an absolute necessity to evaluate their efficiency before including them into routine clinical practice.Hence, the purpose of this study is to evaluate the effect of immediate & delayed post space preparation & sealing ability of new root canal filling material & sealers.
  
  
  OBJECTIVE
  The effect of time of post space preparation on the seal and adaptation of Resilon-Epiphany Se & Gutta-percha-AH Plus Sealer - An SEM study.
  
  
  METHODS
  Eighty extracted permanent maxillary central and lateral incisors selected for the study were decoronated. Roots canals were prepared and obturated.
  
  
  METHODS
  Samples were divided into four groups depending on the time of post, space, preparation and obturated material.GROUP I & II: Immediate and Delayed post space preparation respectively with Gutta-percha / AH Plus as obturating material. GROUP III & IV Immediate and Delayed post space preparation with Resilon / Epiphany as the obturating material. The samples were sectioned, then measured and studied by Scanning Electron Microscope.
  
  
  RESULTS
  There was a significant difference found between immediate and delayed post space preparation in resilon -epiphany group (p<0.001). Similarly significant difference was seen between immediate and delayed post space preparation in AH Plus-GP group (p<0.001). Difference in the adaptation of the two materials was seen in the delayed group (p = 0.030) but the immediate group showed no signifcant difference (p =0.971).
  
  
  CONCLUSIONS
  Within the limitations of this study, immediate post space preparation shows less leakage in both the groups. Resilon-Epiphany shows better results when post space is delayed amongst the two whereas in immediate post space preparation there is no significant difference.
