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 .
Survival of occlusal ART restorations in primary molars placed in school environment and hospital dental setup-one year follow-up study.
OBJECTIVE The objectives of this clinical study were to : evaluate the survival of occlusal atraumatic restorative treatment ( ART ) restorations  , on a longitudinal basis , in the primary molars of children ; and compare the success rate of ART restorations placed in school environment and in hospital dental setup . STUDY DESIGN One dentist placed 120 ART restorations in 60 five- to seven year-olds who had bilateral matched pairs of carious primary molars . A split-mouth design was used to place restorations in school and in hospital dental setup , which were assigned r and omly to contralateral sides . Restorations were evaluated after 6 and 12 months using the ART criteria . RESULTS The survival rate of ART restorations  placed in school environment was 82.2 % at the 6-month assessment and 77.77 % at the 12-month assessment . The success rates of ART restorations  placed in hospital dental setup in the 2 assessment s were 87.7 % and 81.48 % , respectively . There was no statistically significant difference between the ART restorations  placed in school environment and hospital dental setup in both assessment s ( P > O.05 ) . The main cause of failure was the loss of restoration . CONCLUSIONS The one year success rate of occlusal ART restorations in primary molars was moderately successful . The ART technique 's done in hospital dental setup was not proven to be better than restorations placed in school environment
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 .
