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 .
Provision of Atraumatic Restorative Treatment (ART) restorations to Chinese pre-school children--a 30-month evaluation.
OBJECTIVES The objectives of this study were : to provide restorations using the ART approach to pre-school children in Southern China in a kindergarten environment , using a high-strength glass-ionomer restorative material ; to assess the acceptability of this approach and to evaluate on a longitudinal basis the restorations placed . SAMPLE AND METHODS A total of 170 ART restorations were placed in 95 children , aged 5.1 + /- 0.7 years , by seven final-year dental students using st and ard ART procedures and h and instruments . The restorations were evaluated every six months thereafter by two calibrated independent examiners using explorers and mouth-mirrors . RESULTS 93 % of the children reported that they did not feel pain during treatment and 86 % were willing to receive ART restorations again . The cumulative 12- and 30-month survival rates of Class I restorations were 91 % and 79 % , respectively . The corresponding figures for Class V restorations were 79 % and 70 % , while those for Class II restorations were 75 % and 51 % . The failure rates of Class III and IV restorations were high with more than half of them scored as missing within the first year . CONCLUSIONS The ART approach was shown to be acceptable to Chinese pre-school children for providing restorative dental care outside the traditional clinical setting . The success rates were high for Class I and V restorations in primary teeth , modest for Class II , and low for Class III and IV restorations
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 .
