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 .
Comparison of two luting agents used for the retention of cast dowel and cores.
PURPOSE The first purpose of this study was to compare the retentive values of zinc phosphate and Panavia F resin cements when used for luting cast dowel and cores . The second purpose was to determine whether the use of a lubricant when making the resin pattern for a custom dowel and core would have an effect on the final retention of dowels cemented with either zinc phosphate or Panavia F cements . METHODS AND MATERIAL S Sixty-three caries-free extracted single-rooted human teeth were r and omly divided into three groups of 21 .  Root canal preparations were st and ardized for all 63 teeth . Clinical protocol s for fabricating and cementing dowel and core restorations were examined , comparing zinc phosphate and Panavia F resin cements . Direct dowel patterns were fabricated using the Para Post system and cast in a noble metal alloy . Group I dowel spaces were lubricated with GC lubricant prior to dowel pattern fabrication and cleaned with Cavidry solvent before cementing the cast dowel and core with zinc phosphate cement . Group II dowel spaces were rinsed with water only prior to dowel pattern fabrication . The dowels and cores in this group were cemented with Panavia F resin cement . Group III dowel spaces were lubricated with GC lubricant prior to dowel pattern fabrication ; the dowel spaces were cleaned with Cavidry solvent before the cast dowel and cores were cemented with Panavia F cement . The tensile force necessary to remove the cast dowel and cores was determined using a universal testing machine . Results were statistically analyzed using one-way ANOVA and Tukey 's HSD test . RESULTS The dowels and cores in Group I had significantly higher retentive values than either of the two Panavia F groups ( p < or = 0.001 ) . No difference in retentive values ( p > 0.05 ) was found between dowels luted with either of the lubricating agents in the Panavia F groups . CONCLUSIONS Zinc phosphate cement had higher retentive values when cementing cast dowel and cores than Panavia F. The type of lubricant used for the resin dowel fabrication ( water or GC lubricant that was removed with a solvent ) had no effect on the retention of cast dowels cemented with Panavia
