Summary
Bacteria were found under Concise restorations in all tested cavities. Acid etching combined with resin and Concise significantly reduced bacterial presence in dentinal tubules beneath restorations.
Area of Science:
- Dentistry
- Microbiology
- Dental Materials Science
Background:
- Class V Concise restorations are used for permanent molars.
- Assessing bacterial presence beneath restorations is crucial for clinical success.
Purpose of the Study:
- To evaluate bacterial presence under Class V Concise restorations in permanent molars.
- To compare the efficacy of acid etching and resin application in preventing bacterial ingress.
Main Methods:
- Bacteria beneath 58 Class V Concise restorations were registered in vivo.
- Cavities were filled with Concise only, or resin and Concise, with or without prior acid etching.
- Bacterial presence was assessed after 1-4 months.
Main Results:
- Bacteria were found in all cavities with Concise only (13/13).
- Bacteria were found in 14/15 cavities with resin and Concise, 12/15 with acid-etched Concise only, and 8/15 with acid-etched resin and Concise.
- Bacterial occurrence in dentinal tubules was greatest following acid etching.
Conclusions:
- Acid etching combined with resin and Concise significantly reduced bacterial presence compared to Concise alone.
- The findings suggest that acid etching and resin application improve the seal of Concise restorations, reducing bacterial ingress.
