Hypothesis
There is no difference in surface roughness of Class V restorations when using novel tooth-colored restorative materials compared to standard resin-based restorative materials.
Conclusion
Admira Fusion, Filtek, and Beautifil II demonstrated superior surface stability, while Equia Forte HT showed the least favorable performance.
Supporting Evidence
- Admira Fusion showed the smallest changes in surface roughness after five clinical years.
- Equia Forte HT exhibited the most significant surface roughness deterioration after five clinical years.
- Statistical analysis indicated a highly significant difference between Equia Forte HT and the other materials.
Takeaway
This study looked at how different dental materials change over time when exposed to heat and cold. Some materials stayed smooth, while one got rougher.
Methodology
Eighty Class V preparations were restored with four different materials and underwent thermocycling to measure surface roughness at various intervals.
Limitations
The study was limited to specific restorative materials and conditions, and further research is needed to evaluate other factors affecting clinical performance.
