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 .
Amalgam and ART restorations in children: a controlled clinical trial
Objectives The aims of this study were to compare 2-year cumulative survival rates of  amalgam and atraumatic restorative treatment ( ART ) restorations in primary molars and to investigate the determinants of the survival rate of restorations . Material s and methods A controlled clinical trial using a parallel group design was carried out on 258 children aged 6–7 years old , allocated to two treatment groups : conventional restorative treatment using amalgam and ART using high-viscosity glass ionomer . A total of 364 amalgam restorations and 386 ART restorations were placed by three pedodontists in 126 and 158 children , respectively , and were evaluated after 0.5 , 1 , and 2 years . Restorations were placed in vital primary molars with neither pain nor signs of pulp involvement . The survival analysis was conducted using the proportional hazard rate regression model with frailty correction . Results The 2-year cumulative survival rates for all amalgam ( 77.3 % ) and ART ( 73.5 % ) restorations were not statistically significantly different , but there was an effect of “ type of surface ” ( single/multiple ) and “ cavity filling time ” on the survival rates . Both amalgam and ART single-surface restorations had higher survival rates than multiple-surface restorations of the same material . Secondary caries was responsible for 36 and 38 % of failures in amalgam and ART restorations , respectively . Mean time for restoring all type of cavities with amalgam and ART restorations was 13.6 and 13.7 min , respectively . Conclusions Amalgam and ART restorations presented similar survival rates over a 2-year period for all , single-surface , and multiple-surface restorations . Clinical relevance In the cause of finding alternatives to amalgam , ART restorations using high-viscosity glass ionomer might be a suitable option for managing cavitated dentine carious lesions in vital primary molars
