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 .
Performance of atraumatic restorative treatment (ART) depending on operator-experience.
OBJECTIVES Oral health care is not of major interest in developing countries because of lack of infrastructure and professional manpower . Therefore , atraumatic restorative treatment ( ART ) was introduced by the World Health Organization to be performed by dental auxiliary personnel . The aim of this study was to evaluate the performance of ART depending on operator-experience in The Republic of The Gambia . METHODS One hundred twenty-eight newly inserted restorations  were followed up for 12 months using the clinical ART index in a prospect i ve and blinded study design . The patients were r and omly assigned to operators . The clinical performance was compared among three groups : trainees , experienced Community Oral Health Workers ( COHW ) , and professional dentists . The difference in success rates was calculated at a 95 percent confidence interval . RESULTS There was a statistically significant difference between trainees and dentists in performing leakage/gap-free one-surface restorations ( P < 0.05 ) . No significant differences were found between the two groups of auxiliaries ( trainees versus experienced COHWs , P > 0.05 ) . Finally , both groups -- experienced COHWs and dentists -- performed restorations not showing statistically significant differences ( P > 0.05 ) . CONCLUSIONS For The Republic of The Gambia -- especially for areas with underdeveloped medical infrastructure -- training and assignment to perform ART can be recommended for auxiliary dental staff of Community Oral Health Workers
