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 .
Atraumatic restorative treatment (ART): a three-year clinical study in Malawi--comparison of conventional amalgam and ART restorations.
OBJECTIVE This study compares the quality of class I restorations  made with the atraumatic restorative treatment ( ART ) technique and conventional class I amalgam restorations . METHODS The study was carried out among secondary school students in Mzuzu , Malawi . First-year students in 1987 who needed at least two class I restorations were selected . Based on a split-mouth design , each participant received both ART and conventional restorations . The 89 pairs of class I cavities were divided r and omly into two groups , since two different cermet ionomer cement ( CIC ) filling material s were used . Impressions of the restorations and subsequent models were made shortly after restoration , after six months , one year , two years , and three years . The quality of the restorations was determined on the models following the US Public Health Service criteria . Bulk fracture , contour , marginal integrity , and surface texture of the restorations were recorded and evaluated separately . Survival rates were determined by the result ant score of all criteria . RESULTS Though conventional amalgam restorations performed better on all criteria , this difference was significant only for the contour criterion . The survival rates of ART restorations after three years ( 81.0 % ) were lower than those of amalgam restorations ( 90.4 % ) ( P=.067 ) . CONCLUSIONS The quality of ART class I restorations is competitive with that of conventional amalgam restorations
