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 .
Survival rates of two atraumatic restorative treatment (ART) types in occlusal carious permanent teeth after two years.
OBJECTIVE To compare survival rates of Atraumatic Restorative Treatment ( ART ) restorations placed with and without conditioners in occlusal cariouspermanent teeth after two years . MATERIAL AND METHODS The study was an experimental study among children , mean age 13.1 + /- 3.0 years . Two types of ART restorations  were r and omly 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 st and ard 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 ) . CONCLUSION ART restorations placed without tooth conditioners can achieve similar result as those placed with conditioners
