Conclusions ART single-surface restorations  presented high survival percentages in both primary and permanent posterior teeth , whilst ART multiple-surface restorations presented lower survival percentages .
ART sealants presented a high-caries-preventive effect .
Clinical relevance ART is an effective evidence -based option for treating and preventing carious lesions in primary and permanent posterior teeth
Objective The aim of the present study is to up date the results of two previous meta-analyses , published in 2006 and 2012 , on the survival percentages of  atraumatic restorative treatment ( ART ) restorations and ART sealants .
The current meta- analysis includes Chinese publications not investigated before .
One-year survival of occlusal ART restorations in primary molars placed with and without cavity conditioner.
PURPOSE 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 r and omly 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 assessment s were 84 % and 67 % , respectively . There was no statistically significant difference between the ART restorations placed with and without cavity conditioner in both assessment s ( 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
Conclusions ART single-surface restorations  presented high survival percentages in both primary and permanent posterior teeth , whilst ART multiple-surface restorations presented lower survival percentages .
