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 .
Survival of glass ionomer restorations placed in primary molars using atraumatic restorative treatment (ART) and conventional cavity preparations: 2-year results.
OBJECTIVE To compare the survival of  glass ionomer cement ( GIC ) restorations placed in a dental clinic setting using both the atraumatic restorative treatment ( ART ) approach with h and instruments , and conventional cavity preparation with rotary instruments . METHOD AND MATERIAL S Two encapsulated high-strength conventional GICs ( Fuji IX GP , Ketac-Molar Aplicap ) were placed in 82 Class I and 53 Class II preparations and one encapsulated non-gamma 2 amalgam alloy ( GK-amalgam ) was placed in 32 Class I preparations , in the primary molars of 60 Chinese children with a mean age of 7.40 + /- 1.24 ( SD ) years . Thus , 9 treatment groups were formed . RESULTS After two years , there were no significant survival differences found among 7 of the 9 treatment groups ( p = 0.99 ) . However , two groups comprising Fuji IX GP and Ketac-Molar Aplicap placed in Class II cavities prepared using the ART approach showed significantly lower restoration survivals ( p < 0.001 ) . Only 3 of the 72 initially sealed fissures adjacent to the restorations appeared to retain any GIC material . CONCLUSIONS In a clinic setting , both the ART h and instrument and conventional rotary instrument methods were equally suitable for high Class I restoration survival , but not for Class II restoration survival where the conventional cavity preparation method was preferable
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 .
