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 .
An atraumatic restorative treatment (ART) technique: evaluation after one year.
Extraction is the most common dental treatment provided for people in rural and suburban areas in many less-industrialised countries . By comparison , restorative care is rarely provided . In order to improve such situations , a treatment technique has been developed based only on h and excavation of carious lesions and using glass-ionomer cement as a filling material and a sealant . This Atraumatic Restorative Treatment ( ART ) technique follows the concept of minimal intervention and does not require electrically driven equipment . This paper reports on the longevity of fillings and sealants placed using the technique under field conditions in rural Thail and .  Dental caries was treated using the ART technique in one village , whilst the population in a second village received restorative care ( amalgam fillings ) through mobile dental units . A third village was the control . After one year , 79 per cent of single surface ART fillings and 55 per cent of ART fillings of greater than one surface placed in deciduous teeth were judged successful . The success rate of ART fillings  in the permanent dentition ( mainly single surface fillings ) was 93 per cent and the retention rate for sealants was 78 per cent . Children were pleased at having received treatment by this technique and showed little fear . The ART technique is a promising caries treatment procedure for use in rural and sub-urban areas in less-industrialised countries
