CONCLUSION ART restorations have similar survival rate compared to conventional treatment and can be considered an option to restore occlusoproximal cavities in primary molars
BACKGROUND A previous systematic review showed that atraumatic restorative treatment ( ART ) can be an option to restore the occlusoproximal cavities in primary teeth ; however , few studies fulfilled the criteria of inclusion to generate a high level of evidence .
AIM To up date the existing systematic review and address questions regarding survival rate of ART restorations compared to the conventional approach in occlusoproximal cavities in primary molars .
Is high-viscosity glass-ionomer-cement a successor to amalgam for treating primary molars?
OBJECTIVES To assess and compare the cumulative survival rate of amalgam and atraumatic restorative treatment ( ART ) restorations in primary molars over 3 years . METHODS 280 children aged 6 - 7 years old were enrolled in a cluster r and omized controlled clinical trial using a parallel group design covering two treatment groups : conventional restorative treatment with amalgam ( CRT ) and atraumatic restorative treatment ( ART ) using a high-viscosity glass-ionomer ( HVGIC ) Ketac Molar Easymix . Three pedodontists placed 750 restorations ( 364 amalgam and 386 ART in 126 and 154 children , respectively ) which were evaluated at 0.5 , 1 , 2 and 3 years . The proportional hazard rate regression model with frailty correction , ANOVA and Wald tests , and the Jackknife procedure were applied in analysing the data . RESULTS The cumulative survival rates over 3 years for all , single- and multiple-surface CRT/amalgam restorations ( 72.6 % , 93.4 % , 64.7 % , respectively ) were no different from those of comparable ART/HVGIC restorations ( 66.8 % ; 90.1 % and 56.4 % , respectively ) ( p=0.10 ) . Single-surface restorations had higher survival rates than multiple-surface restorations for the both treatment procedures ( p<0.0001 ) . A higher proportion of restorations failed because of mechanical reasons ( 94.8 % ) than of secondary caries ( 5.2 % ) . No difference in reasons for restoration failures between all types of amalgam and ART/HVGIC restorations were observed ( p=0.24 ) . SIGNIFICANCE The high-viscosity glass-ionomer used in this study in conjunction with the ART is a viable option for restoring carious dentin lesions in single surfaces in vital primary molars
