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 .
Evaluation of Class I ART restorations in Brazilian schoolchildren: three-year results.
Atraumatic Restorative Treatment ( ART ) has been adopted around the world to avoid unnecessary extraction s , especially in non-industrialized countries . The development of specific glass ionomer cements marketed for the ART technique has contributed to the technical success rate . In this study , Ketac-Molar ( 3 M ESPE , Dental Medzin , Germany ) was used to restore 150 Class I cavities in 118 Brazilian public school children , aged from 7 - 12 years . At baseline and at subsequent recalls , CPI probes with a ball-end of 0.5 millimeters ( mm ) were used to assess loss of restorative material , and photographic color transparencies of restorations were made . After six months , 83 patients returned for follow-up examinations , with 71.8 % of their restorations design ated as acceptable . After three years , 49 patients with 57 ART-restorations were evaluated , with 21.0 % of these restorations grade d as acceptable . Another 29.8 % of their restorations had been replaced by more permanent material s. The main objective of the ART technique is tooth retention ; this was achieved for 94.7 % of the restored teeth in a high caries risk population who returned for recalls
