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 .
The influence of luting cement on the probabilities of survival and modes of failure of cast full-coverage crowns.
OBJECTIVES This study compares the probabilities of survival and modes of failure of cast full-coverage crowns bonded with five cements when subjected to tensile pull-off testing . METHODS Five groups of 25 sound human premolar teeth were prepared for full-coverage crowns , impressions recorded and customized castings fabricated in Ni-Cr-Mb bonding alloy . The cements tested were zinc phosphate , a h and -mixed and capsulated conventional glass-ionomer cement , a resin-modified glass-ionomer cement and a resin composite luting cement . The cemented crowns were stored in water at 37 degrees C for 24 h prior to application of a tensile pull-off force at a strain rate of 10 mm/min . The loads at failure were ranked and modelled by derived Weibull functions each describing the probability of a given specimen failing under a given load . Non-parametric statistical analysis was also applied to the results . RESULTS There were no significant differences between the loads at failure of zinc phosphate cement , the h and -mixed or the capsulated glass-ionomer cements . The resin-modified glass-ionomer cement and the resin composite cement  failed at significantly higher loads than the other three cements , but were not significantly different from each other . The Weibull modulus ranking for each cement from highest to lowest was resin composite = zinc phosphate , resin-modified glass-ionomer , h and -mixed conventional glass-ionomer and capsulated conventional glass-ionomer cement . SIGNIFICANCE Weibull analysis allows dentists to compare the probability of survival of a crown bonded with different cements at a chosen load giving an indication of cement reliability
