| Résumé : | Purpose: The micropercolation testing of dental materials is currently used to evaluate the sealing ability. The aim of the present study is to compare the sealing ability of distinct assembling materials for zirconium oxide peripheric crowns. Materials and Methods: One hundred teeth were prepared to be thermocycled after being distributed at random in 10 groups each containing 10 specimens (group 1: Fuji One; group 2: Fuji Plus; group 3: Variolink II; group 4: RelyX Ultimate; group 5: Multilink; group 6: Panavia F2.0; group 7: Bifix QM; group 8: RelyX Unicem 2; group 9: Maxcem Elite; group 10: Bifix SE). Results: RelyX Unicem 2 and RelyX Ultimate yielded high imperviousness percentages. The sealing ability in the vestibular area and lingual area is indeed best in the presence of these two materials. Our results show no difference whether the chamfer is situated in the enamel or in the dentin. Conclusion: A zirconium crown should be preferably cemented with a glass-ionomer cement modified by addition of resin material. |
