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 .
Clinical Trial of a New Glass Ionomer for an Atraumatic Restorative Treatment Technique in Class I Restorations Placed in Latvian School Children
Objective : The aim of this study was to evaluate the performance of a new glass ionomer filling material ( ChemFlex ™ ) using the atraumatic restorative treatment ( ART ) approach in class I cavities in the permanent dentition of Latvian schoolchildren . Methods : A total of 63 fillings ( 40 test and 23 control ) were placed using the ART technique in 41 schoolchildren in Riga at the Stomatology Institute of the Medical Academy of Latvia . These fillings were then blindly assessed after 2 years . Results : The complete success rate for both the test and the control material fillings were 92.5 and 94.9 % , respectively . Conclusion : The new glass ionomer filling has shown a good performance in terms of retention , marginal failure and fractures in class I cavities
