Effect of Different Techniques of Removal of Residues of Silicon fit Disclosing Agent on the Retention of Ceramo-Metal Crowns Cemented with Resin-Reinforced Glass Ionomer Luting Cement

Objective. This study was conducted to determine if the retention of permanently cemented crowns is affected by the use of a silicone fit disclosing agent. Background. Earlier research has shown that the retention of metal cast restorations may be compromised when cemented after the use of a silicone fit checker. To date, one of the cements of choice for definitive cementation of ceramo-metal crowns is resin reinforced glass ionomer, (Fuji Plus, GC America). There is little information in the dental literature comparing the effect of different cleaning methods in the removal of the fit indicator media used to assess the fit of the crown. Methods. For this study the retention of cast copings was measured after four different cleaning techniques were applied to remove the fit silicon disclosing agent residues. Results and Conclusions. Will be presented at HPD Research Day. Grants. This study was funded by a grant from the Health Professional Division.
