title: Survival rates of two atraumatic restorative treatment (ART) types in occlusal carious permanent teeth after two years.
abstract: OBJECTIVE
  To compare survival rates of Atraumatic Restorative Treatment (ART) restorations placed with and without conditioners in occlusal cariouspermanent teeth after two years.
  
  
  METHODS
  The study was an experimental study among children, mean age 13.1 +/- 3.0 years. Two types of ART restorations were randomly placed on 186 occlusal carious permanent teeth on contralateral sides using split mouth design. Ethical clearance to conduct the study was obtained from the UI/UCH Review Committee. ART was performed using GC Fuji IX GP and teeth that were conditioned with GC Dentine Conditioner. Time taken to place restorations and average material cost were recorded. Follow-up of subjects to evaluate integrity of restorations was conducted at 6 monthly intervals by one independent examiner. Proportions and percentages were generated; student t-test was used to compare means. Cumulative survival rates were determined by the coded scores and standard criteria for evaluating ART restorations.
  
  
  RESULTS
  There was no significant difference in the mean time for placing ART restorations with or without conditioners and in the cumulative survival rates of both treatment types after 2 years (p > 0.05).
  
  
  CONCLUSIONS
  ART restorations placed without tooth conditioners can achieve similar result as those placed with conditioners.
