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 .
A two-year clinical evaluation of glass ionomer and ormocer based fissure sealants.
UNLABELLED The objective of the present study provides further data comparing retention , marginal integrity and caries preventive effects of two fissure sealants ( glass ionomer based ; GC Fuji VII Capsule [ Fuji VII ] and ormocer based ; Admira Seal [ AS ] )  in children . This study was design ed as a r and omized single-blind clinical trial . The permanent first molars ( PFMs ) of 50 children , 7 - 13 years of age ( mean age : 8.9 + /- 1.3 years ) , were sealed with a split-mouth design . Fissure sealants applied to the PFMs according to the manufacturer 's recommendations by one pediatric dentist . Clinical evaluation of the sealants was carried out to record retention , marginal integrity and presence of caries at 6 , 12 , 18 and 24 months after placement by the other pediatric dentist . Kaplan-Meier survival analysis and Cox 's regression models were used to estimate the probability of two sealants success . RESULTS Alpha and Bravo retention rates at the end of follow-up were 13 % and 80 % for Fuji VII and 3 % and 83 % for AS , respectively . For retention and marginal integrity between fissure sealants was found similar survival rates ( p > 0.05 ) . After 24 months , presence of caries was 16 % for Fuji VII and 32 % for AS ( p < 0.05 ) . CONCLUSION Fuji VII and AS exhibited similar retention and marginal integrity during 24 months . However Fuji VII was showed better results than AS for caries preventive effect . Consequently , Fuji VII sealants may be a better choice for preventing occlusal caries
