- Abstract
Aim: The objective of the present study was to evaluate the microleakage of composite restorations alone or with amalgam base in proximal box of class Ⅱ cavity preparation. Method: Eighty proximal cavities (Mesio-occlusal and disto-occlusal) were prepared in 40 premolars with carbide bur and randomly divided into four groups. Group A restored with composite resin; the other three groups restored with combined amalgam-composite restoration as follows. Group B the composite inserted immediately after insertion of amalgam, group C the composite inserted after 5 minutes of amalgam insertion while in group D the composite inserted after two days of amalgam insertion. Marginal adaptation was evaluated at the following interfaces: tooth-amalgam(T-A), tooth-composite resin (T-C) and amalgamcomposite (A-C). Microleakage was evaluated by means of methylene blue infiltration after 21 days water storage and thermocycling aging. Microleakage was assessed by measuring the depth of horizontal dye penetration. Image J analysis software was used to measure the penetration of dye in the tooth- filling interface and in the amalgam- composite interface. One-way ANOVA and post-hoc Tukey HSD tests (α =0.05) were used statistically for analyzing gather data. Results: There were a significant statically showed by ANOVA test between teeth -fillings interface, according to Tukey’s test there were a significant difference between teeth-composite interface and teethamalgam interface (p<0.05), while between composite- amalgam interface, ANOVA test showed a significant difference between groups and Tukey’s test showed a significant difference between groups according to time of placement of composite on amalgam filling (p<0.05). Conclusion: Using of amalgam at the cervical base of the box in Class II combined amalgam-composite restoration has better result than using of composite from marginal leakage view.
