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 .
The effect of GIC-brand on the survival rate of proximal-ART restorations.
BACKGROUND Laboratory studies show diverse behaviour of different br and s of glass-ionomer cements  ( GIC ) . AIM This study investigated the clinical performance [ survival rate ( SR ) ] of three GIC br and s applied to proximal atraumatic restorative treatment ( ART ) restorations . Additionally , the SR of the tooth was evaluated . DESIGN Proximal cavities of 262 primary molars were restored . The patients had been r and omly allocated to two operators and three GIC br and s :  Fuji IX , Hi-Dense , and Maxxion R. Restorations were evaluated after 1 , 6 , 12 , 18 , 24 , 30 , and 36 months . Failed restorations were , if possible , repaired or replaced . Linear regression analyses were used to evaluate the effect of GIC br and , operator , and surface of restoration . Kaplan-Meier survival analysis and log-rank test were performed for both restoration survival and tooth survival ( α = 5 % ) . RESULTS After 3 years , 82.4 % of the restorations were evaluated . The SR of the restorations was 24.4 % , and there was no difference among GIC br and s ( log-rank test , P = 0.6 ) . In the first 18 months , a significant operator effect and significantly higher failures in distal surfaces were found . The SR of the tooth was 81.7 % . CONCLUSIONS The SR of proximal ART restorations was relatively low when compared with the SR of the tooth . There are no differences in the performance among the GIC br and s used in the study
