Conclusion : Within the limitations of this study , thein vitro literature seems to suggest that the use of self-adhesive resin cements shows higher retentive strength , followed by resin-modified glass-ionomer cement ( RM-GIC ) and conventional GIC .
However , RM-GIC can be a preferred luting agent due to its clinical advantages over resin cements .
Thus , it can be concluded that choice of cement will depend on individual patient needs and clinical situation
Background : Stainless steel crowns ( SSCs ) are unique coronal restorative material s used commonly in the management of primary teeth with extensive caries .
Aim : The aim of this study was to perform a systematic review to evaluate the retentive strength of luting cements for SSCs .
A comparative study of retentive strengths of zinc phosphate, polycarboxylate and glass ionomer cements with stainless steel crowns--an in vitro study.
This study was conducted on 30 extracted human primary molars to assess the retentive strengths of zinc phosphate , polycarboxylate and glass ionomer cements . The teeth were embedded in resin blocks and were r and omly divided into 3 groups of 10 each . The occlusal surfaces of all teeth were reduced uniformly by 1.0 to 1.5 mm . All mesial , distal undercuts were removed and sharp angles rounded . This was followed by cementing pretrimmed and precontoured stainless steel crowns on each tooth with h and pressure and storing in artificial saliva at 37 degrees C for 24 hours . Retentive strength was tested using Instron Universal Testing Machine . The load was applied starting from a zero reading and gradually increased until the cemented stainless steel crowns showed signs of movement and then the readings were recorded . It was found that retentive strengths of zinc phosphate and glass ionomer cements were statistically better ( P < 0.05 ) when compared to the polycarboxylate cement . Negligible difference ( 0 . 59 kg/cm2 ) was however observed between zinc phosphate and glass ionomer cements
