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 .
Clinical evaluation of three caries removal approaches in primary teeth: a randomised controlled trial.
OBJECTIVE To evaluate the clinical performance and radiographic outcome of glass ionomer cement ( GIC ) restoration in primary molars using three caries removal techniques . BASIC RESEARCH DESIGN R and omised clinical controlled trial . CLINICAL SETTING Two st and ard dental clinics in 2 hospitals near Bangkok . PARTICIPANTS A total of 276 children , aged 6 - 11 , having dentinal caries on the occlusal and /or proximal surface extending at least one-third of dentine without signs and /or symptoms of irreversible pulpitis . INTERVENTION Children were r and omly allocated into 3 study groups with different caries removal techniques : Group 1 , partial soft caries removal at enamel-dentine junction ( EDJ ) by spoon excavation ; Group 2 , complete soft caries removal by spoon excavation ; and Group 3 , conventional caries removal by steel burs . All cavity preparations were restored with GIC ( Fuji IX , GC Corp. , Japan ) . MAIN OUTCOME MEASURES Clinical and radiographic evaluations were carried out at 6 and 12 months after restoration . RESULTS After 12 months , 89 , 89 , and 88 restorations in Groups 1 , 2 and 3 were evaluated . The cumulative survival rates of GIC restorations in Groups 1 , 2 and 3 were 83 % , 83 % , and 89 % while the cumulative survival rates of pulp were 99 % , 100 % and 98 % respectively . There were no statistically significant differences in the survival of GIC restorations  or pulp in the three groups ( p > 0.05 ) . CONCLUSION The clinical and radiographic evaluations after 12 months indicated that partial soft caries removal at EDJ followed by GIC restoration was comparable to that of ART and conventional approaches
