Title

EFFECT OF TOTAL ETCH AND UNIVERSAL ADHESIVES ON MICROLEAKAGE BETWEEN COMPOSITE AND GLASS IONOMER IN CLASS II SANDWICH RESTORATIONS

Pages

  62-70

Abstract

 Background and purpose: Microleakage is the most common cause of secondary caries and failure of restorations. The aim of this study was to evaluate the Microleakage between resin modified glass-ionomer (RMGI) and resin COMPOSITE in sandwich restorations using different bonding agents. Materials and methods: Forty four premolars were used in this experimental study. Class II cavities were prepared and the gingival margin placed 1 mm below cementoenamel junction. RMGI (Fuji II LC) was inserted on the gingival floor in 1 mm thickness and the teeth were divided into two groups. Group I: cavities were etched, rinsed and treated with a TOTAL ETCH adhesive (Adper single bond 2). Group II: An universal adhesive (Single bond universal) was applied in self etch mode. All cavities were then restored incrementally using resin COMPOSITE (Filtek Z 250). To evaluate the microleakage, the samples were subjected to thermocycling (3000 cycles), immersed in methylene blue for 72 hours, and sectioned mesiodistally. The samples were subsequently observed under stereomicroscope. Mann-Whitney test was used to analyze the data (P<0. 05). Results: The microleakage was significantly higher in Adper single bond 2 group (520. 5± 401. 5µ m) compared with that in single bond universal group (193± 269. 5µ m). Conclusion: This study showed that application of universal adhesive between RMGI and COMPOSITE in self etch mode leads to lower microleakage compared with TOTAL ETCH adhesive in open sandwich restorations.
