TI  - In Vitro Evaluation of the Shear Bond Strength of Different Luting Cements on Zirconium Oxide Specimens in Primary Teeth
AB  - Objective: Nowadays in pediatric dentistry clinics, zirconia crownshave become widespread restoration choice of primary teeth withextensive decay. Aim of this study was to evaluate shear bondstrength of different luting cements on zirconium oxide (zirconia)specimens in primary teeth.Methods: Eighty extracted primary molar teeth were selectedfor the study and teeth were randomly divided into four groups.Eighty zirconium oxide specimen were fabricated using CAD/CAMtechnology. Samples were cemented with zinc polycarboxylatecement (PK), conventional glass ionomer cement (GCIS), resinmodified GCIS (RMCIS) and self adhesive resin cement (RS). Aftercementation, samples were kept in distilled water for three days atroom temperature. Then speciemens were subjected to 1000 cyclesthermal cycle process. Shear bond strength was determined usinguniversal testing machine, debonded surfaces were examined usingstereomicroscope. Tamhane’s test was used for pairwise comparisonsof the mean bonding forces of the groups. Pearson chi-square testwas used to compare the debonded surfaces. Significance level (p)was accepted as 0.05 in the application of the tests.Results: Mean bond strength of RMCIS group was statisticallylower than RS, GCIS and PK cements (p<0.05). There wasn'tstatistically significant difference between mean bonding strength ofRS, GCIS and PK cement group (p>0.05). There wasn't statisticallysignificant difference between debonded surfaces of zirconiaspecimen after cementation with different bonding cements(p>0.05). Conclusion: We think that it may be more advantageous to adherezirconia crowns with self adhesive RS in pediatric patients whom aredifficult to provide moisture control.
