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 .
Low-cost glass ionomer cement as ART sealant in permanent molars: a randomized clinical trial.
Clinical trials are normally performed with well-known br and s of glass ionomer cement ( GIC ) , but the cost of these material s is high for public healthcare in less-affluent communities . Given the need to research cheaper material s , it seems pertinent to investigate the retention rate of a low-cost GIC applied as atraumatic restorative treatment ( ART ) sealants in two centers in Brazil . Four hundred and thirty-seven 6-to-8-year-old schoolchildren were selected in two cities in Brazil . The children were r and omly divided into two groups , according to the tested GIC applied in the first permanent molars . The retention rate was evaluated after 3 , 6 and 12 months . Kaplan-Meier survival analysis and the log-rank test were performed . The variables were tested for association with sealant longevity , using logistic regression analyses ( α = 5 % ) . The retention rate of sealants after 12 months was 19.1 % . The high-cost GIC br and presented a 2-fold-more-likely-to-survive rate than the low-cost br and ( p < 0.001 ) . Significant difference was also found between the cities where the treatments were performed , in that Barueri presented a higher sealant survival rate than Recife ( p < 0.001 ) . The retention rate of a low-cost GIC sealant br and was markedly lower than that of a well-known GIC sealant br and
