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 .
An ART field study in western Nepal.
AIM To evaluate the effectiveness of three different types of  glass ionomer restorations placed in children 's teeth using the ART technique two years after placement by either dentists or primary health care workers . SETTING The rural district of Palpa in western Nepal . METHOD An opportunistic non-r and omised field study , commenced in April 1997 . Three different glass ionomer restorative cements were used : Fuji IX ( GC ) , Dentsply Baseline ( DENTSPLY/DeTrey ) , and S.S. WhiteR ( S.S. White ) . The restorations were assessed two years later by an independent evaluator , who was blind to the type of restorations used and also blind to the operators . RESULTS Four primary health care workers and two dentists restored 163 primary and permanent teeth using h and instruments . One and two surface restorations were placed in 105 students ranging from 3 to 19 years of age from seven schools . After two years , 79 ( 75 % ) of the restorations survived and 27 ( 25 % ) failed , while 100 % of 21 evaluated single surface restorations placed on permanent molars with Fuji IX survived . There was no statistically significant difference in the survival of the restorations placed by dentists and placed by primary health care workers , which corroborates that both groups are both capable of performing the technique satisfactorily . CONCLUSIONS ART is very effective for one surface permanent molars using improved glass ionomer cements design ed for the ART technique
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 .
