Class I restorations and restorations placed using rubber dam presented better AFR .
An elevated number of failures were observed due to recurrent caries , highlighting the need for professionals to work with a health-promoting approach .
BACKGROUND Several restorative material s with specific indications are used for filling cavities in primary teeth .

Conventional versus resin-modified glass-ionomer cement for Class II restorations in primary molars. A 3-year clinical study.
OBJECTIVE To compare the clinical performance of two glass-ionomer cements (GICs)for  Class II restorations in primary molars : a conventional cement ( Fuji II ) and a resin-modified cement ( Vitremer ) . DESIGN Split mouth and r and om assignment to the two material s were used for the majority of the molars . SAMPLE AND METHODS Forty consecutive 4 - 7-year-old children were included . One operator made 115 restorations : 53 with Vitremer and 62 with Fuji II . The restorations were evaluated clinical ly , radiographically and from colour photographs . RESULTS The cumulative success rate of the Vitremer restorations was 94 % and that of the Fuji II restorations 81 % . The difference is statistically significant . The risk of a failed restoration was more than five times higher with Fuji II than with Vitremer as the restorative material . Of the 13 unsuccessful restorations , seven had lost their retention , four had secondary caries , and two were fractured . CONCLUSIONS The resin-modified GIC offered advantages over the conventional GIC for restoring approximal caries in primary molars
