In Vitro Comparison of Microleakage of four Different Luting Cements for Cementation of Stainless Steel Crowns in the Primary Teeth |
|
| چکیده انگلیسی مقاله |
Statement of Problem: One of the complications in reconstruction of the primary teeth with stainless steel crowns (SSC) is microleakage at the crowns' margins. Luting cement that can seal the margins can reduce the microleakage. Purpose: This research was performed to compare the ability of four adhesive cements for reducing microleakage at the SSC margins. Methods and Material: In this experimental study, standard preparation was performed on 60 primary molar teeth for SSC restorations. After adjusting SSC, the samples were randomly divided into 5 groups, each containing 12 teeth. Then, the SSCs were cemented in each group with different cements. These groups contained Zincphosphate (Elite, ZP), Polycarboxylate (Durelon, PC), Glass ionomer (Ketac cem, GI), Resin-modified glass ionomer (Rely X luting 2,RMGI), and Resin-modified glass ionomer with bonding agent ((Single Bond,SB) . After thermocycling and using dye penetration (methylen blue 1%), the samples were evaluated under a digital microscope. For comparison of the microleakages among the groups, t-test, ANOVA and LSD tests were used. Result: Microleakage in the adhesive cement groups (GIC, RMGIC, RMGIC+BA) was significantly lower than that in the non-adhesive (ZP, PC) groups ( p < 0.05). Comparison of the cements revealed a statistically significant difference among all the groups ( p < 0.001). RMGI+SB had the lowest microleakage followed by RMGI, GI, ZP. PC cement showed the greatest microleakage. Conclusion: Adhesive cements were more effective in reducing the microleakage in cementation of SSC than non-adhesive cements. The use of bonding agents with RMGI cement showed more acceptable results in comparison with RMGI cement. |
