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 .
Glass ionomer ART sealant and fluoride-releasing resin sealant in fissure caries prevention – results from a randomized clinical trial
Background The relative performance of ART sealant and fluoride-releasing resin sealant in preventing fissure caries in permanent molars was compared in a r and omized clinical trial conducted in southern China ( Clinical Trials.gov NCT01829334 ) . Methods After obtaining ethical approval , healthy schoolchildren who had permanent first molars with occlusal fissures which were sound but deep or presented with only incipient caries were recruited for the study . Included molars were r and omly allocated into one of four parallel study groups in units of left/right teeth per mouth . Two of the four groups adopted the methods of ART or fluoride-releasing resin sealant placement while the other two groups adopted the topical fluoride application methods .  Fissure status of the molars in each group was evaluated every 6 months . Development of dentine caries and sealant retention over 24 months in the molars in the two sealant-using groups was compared in this report . Outcome on cost-effectiveness of all four groups over 36 months will be reported elsewhere . Results At baseline , a total of 280 children ( 383 molars ) with mean age 7.8 years were involved for the two sealant groups . After 24 months , 261 children ( 357 molars ) were followed . Proportions of molars with dentine caries were 7.3 % and 3.9 % in the ART sealant and fluoride-releasing resin sealant groups , respectively ( chi-square test , p = 0.171 ) . Life-table survival analysis showed that sealant retention ( full and partial ) rate over 24 months for the resin sealant ( 73 % ) was significantly higher than that ( 50 % ) for the ART sealant ( p < 0.001 ) . Molar survival ( no development of dentine caries ) rates in the ART sealant ( 93 % ) and fluoride-releasing resin sealant ( 96 % ) groups were not significantly different ( p = 0.169 ) . Multilevel logistic regression ( GEE modeling ) accounting for the effects of data clustering and confounding factors confirmed this finding . Conclusions Though the retention of fluoride-releasing resin sealant was better than that of the ART sealant , their effectiveness in preventing fissure caries in permanent molars did not differ significantly over 24 months . ART sealants could be a good alternative when and where re sources for resin sealant placement are not readily available
