Studies investigating restorations placed in the primary dentition showed no significant differences between the groups after 12 and 24 months .
In the permanent dentition , the longevity of ART restorations is equal to or greater than that of equivalent amalgam restorations for up to 6.3 years and is site-dependent .
No difference was observed in primary teeth .
The aim was to report on the longevity of  restorations placed using the atraumatic restorative treatment ( ART ) approach  compared with that of  equivalent placed amalgam restorations .
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
