In vitro study reveals microbial leakage differences in various restorative materials, indicating clinical implications.
Key Points
The study aims to investigate how different restorative materials impact microbial leakage and marginal adaptation in proximal cavities.
Conducted on 66 human third molars with standardized Class II cavities.
Used a dual-chamber model with Streptococcus mutans to assess microbial leakage over 40 days.
Employed qualitative analysis through scanning electron microscopy and various statistical methods including Kaplan-Meier analysis.
Significant differences in microbial leakage were observed among restorative materials, with a notable difference between Cention N and Filtek Z350XT (p = 0.037).
Cention N showed a longer average time before microbial leakage occurred compared to other materials.
Qualitative SEM analysis supported findings on the interfacial properties of the restorations.
