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 atraumatic restorations in primary molars: a comparison between 2 glass ionomer cements.
Dental caries continues to be a highly prevalent disease among Brazilian preschoolers , especially those with low socioeconomic status . The purpose of this r and omized , controlled trial was to evaluate in vivo 245 simplified  restorations  in deciduous molars using glass ionomer cements ( Vidrion R and Ketac-Molar ) . Dental restorations were evaluated at 6- and 12-month follow-ups . The teeth restored with Vidrion R ( SS White ) on a single tooth surface were successful in 87 % of the cases evaluated at 6 months and in 63 % at 12 months . The teeth restored with Ketac-Molar on one surface achieved a success rate of 95 % at 6 months and 82 % at 12 months . No recurrent caries or pulpal infection was evident . Logistic regression analysis demonstrated that teeth with cavities restricted to the occlusal surface on sclerotic dentin showed the best adhesion to the restorative material . The restorations with Ketac-Molar had a better clinical performance than those with Vidrion
