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 .
AIM To systematic ally review the literature in order to investigate the longevity of primary teeth restorations  and the reasons for failure .
Clinical performance of a compomer and amalgam for the interproximal restoration of primary molars: a 24-month evaluation
Objectives To evaluate the clinical performance of a compomer material ( Dyract ® ) in comparison with dental amalgam ( Contour ® ) for management of proximal caries in primary molars in young children . Setting General dental practice , and a dental hospital paediatric clinic . Method This was a prospect i ve study . A split mouth design was used with identical pairs of minimal Class II cavities , of matched tooth type inthe same dental arch , usually diagnosed with the use of bitewing radiographs . Seventy-eight pairs of restorations were completed ofwhich 60 pairs were available for evaluation after 24 months . Results Comparable retention rates were observed for both Dyract and amalgam . The retention rates were high for both material s , with only four amalgam and two Dyract restorations failing over 24 months . Significantly better marginal integrity ( P < 0.05 ) was observed for Dyract compared with amalgam with no significant differences between the two material s for recurrent caries , wear or surface texture . Conclusions Dyract seemed to be a suitable alternative to amalgam for proximal restorations in primary molars of young children for use in general dental practice
