title: One-year survival of occlusal ART restorations in primary molars placed with and without cavity conditioner.
abstract: OBJECTIVE
  The objectives of this clinical study were to: evaluate the survival of occlusal atraumatic restorative treatment (ART) restorations, on a longitudinal basis, in the primary molars of children in Mosul/Iraq; and compare the success rate of ART restorations placed with and without cavity conditioning.
  
  
  METHODS
  One dentist placed 96 ART restorations in 48 6- to 7-year-olds who had bilateral matched pairs of carious primary molars. A split-mouth design was used to place restorations with and without cavity conditioning, which were assigned randomly to contralateral sides. Restorations were evaluated after 6 and 12 months using the ART criteria.
  
  
  RESULTS
  The survival rate of ART restorations placed with cavity conditioner was 89% at the 6-month assessment and 74% at the 12-month assessment. The success rates of ART restorations placed without cavity conditioning in the 2 assessments were 84% and 67%, respectively. There was no statistically significant difference between the ART restorations placed with and without cavity conditioner in both assessments (P>0.05). The main cause of failure was the loss of restoration.
  
  
  CONCLUSIONS
  The 1-year success rate of occlusal ART restorations in primary molars was moderately successful. The ART technique's cavity conditioning step was not proven to be better than not using it for Class I lesions.
