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 .
COMPARISON OF TWO MINIMALLY INVASIVE METHODS ON THE LONGEVITY OF GLASS IONOMER CEMENT RESTORATIONS: SHORT-TERM RESULTS OF A PILOT STUDY
The purpose of this study was to evaluate the clinical performance of glass ionomer cement ( GIC ) restorations comparing two minimally invasive methods in permanent teeth after 12 months . Fifty pregnant women ( second trimester of pregnancy ) , mean age 22 ± 5.30 years , were treated by two previously trained operators . The treatment approaches tested were : chemomechanical method ( CarisolvTM ; MediTeam ) and atraumatic restorative treatment ( ART ) . A split-mouth study design was used in which the two treatments were r and omly placed in 50 matched pairs of permanent teeth . The chemomechanical method ( CM ) was the test group and the ART was the control group . The treatments were performed in Public Health Centers . The tested restorative material was a high-strength GIC ( Ketac Molar ; 3M/ESPE ) . The restorations were placed according to the ART guidelines . Two calibrated independent examiners evaluated the restorations in accordance with ART criteria . The interexaminer kappa was 0.97 . Data were analyzed using 95 % confidence interval on the binomial distribution and Fisher 's exact test at 5 % significance level . In a 12-month follow-up , 86 % of the restorations were evaluated . In the test group ( CM ) , 100 % ( CI=93.3 - 100 % ) of the restorations were considered successful . In the control group ( ART ) 97.6 % ( CI=87.4 - 99.9 % ) of the restorations were considered successful and 2.4 % unsuccessful ( marginal defect > 0.5 mm ) . There was no statistically significant difference between the 12-mounth success rate for both groups ( Fisher 's exact test : P=0.49 ) and between the two operators ( Fisher 's exact test : P=1.00 ) . Both minimally invasive methods , chemomechanical method and ART , showed a similar clinical performance after 12 months of follow up
