Title

COMPARATIVE STUDY OF MICROLEAKAGE OF FULL CROWN RESTORATIONS LUTED WITH ARIADENT AND HARWARDZINC PHOSPHATE CEMENTS

Pages

  50-59

Abstract

 Film thickness, strength, solubility and MICROLEAKAGE of DENTAL CEMENTS are essential factors in cement selection by dentist. Since failure of metal ceramic restorations is mostly due to their marginal leakage and provious studies have shown that MICROLEAKAGE of Resin, Glassionomer and Zincphosphate cements are different, this study was done to compare the rate of MICROLEAKAGE between Ariadent and Harward ZINC PHOSPHATE CEMENTS. In the case of observing no difference in MICROLEAKAGE of two cements Ariadent zinc phosphate cement which is more available than Harward zinc phosphate cement can be recommended. Frothy sound permanent premolar teeth extracted for orthodontic purposes were used. Standard metal ceramic preparation had been performed for all the teeth. In each tooth shoulder and chamfer finishing lines had been produced in labial and lingual surfaces respectively. After preparation of metal copings the prepared teeth were randomly divided into two experimental groups. In one group copings were cemented by Ariadent zinc phosphate cement and in the other group Harward zinc phosphate cement was used for luting. Both groups were sectioned buccolingually. The amount of dye MICROLEAKAGE was measured by stereomicroscope and non parametric willcoxon test was used for data analysis. Results showed that the mean of dye MICROLEAKAGE in Ariadent zinc phosphate cement in labial (1.4±1.17) and lingual surfaces (1.81±1.4) were less than those in Harward zinc phosphate cement (1.71±0.84 and 1.97±1.05 respectively). There was no significant difference in MICROLEAKAGE between the two experimental groups.
