| Summary: | The purpose of this study is to evaluate the cost effectiveness of posterior
composite resin through the amount of microleakage.
Materials and Methods: 72 Cl V cavities were prepared in 36 teeth (extracted upper first
premolar), one buccally and one palatally in each tooth, the cavities were located in the
middle third of the crown.
The teeth were randomly divided into three groups (24 cavities for each group);
Group A: filled with Helio- molar radiopaque composite.
Group B: filled with Tetricceram composite.
Group C: filled with an Ariston PHc composite .
After the teeth were filled, they were restored in normal physiological saline in an incubator
at 37 oC. one third of each group (8 cavities) were thermocycled for one day (30 cycle), 2nd
third thermocycled for 10 days (300 cycle), and the last third thermocycled for 100 days
(3000 cycle).
One-way-ANOVA-analysis revealed significant differences among the groups
(p<0.05) in the terms of the cost effectiveness, The results revealed that the Ariston Phc
composite has better cost effectiveness from the other tested types. It is not a significant
difference between Group C and B, and it is a significant difference between Group C and A.
Material C has better cost effective than other tested materials. None of the
materials tested was able to achieve the absolute cost effectiveness. |
