Hypothesis
Disinfecting dentin with chlorhexidine does not significantly affect interfacial microleakage or the bond strength of a universal adhesive to dentin in either self-etch or etch-and-rinse modes.
Conclusion
Chlorhexidine adversely affects bond strength to dentin when using universal adhesives in self-etch mode, but does not significantly impact bond strength in etch-and-rinse mode.
Supporting Evidence
- Microleakage was not significantly influenced by the etching mode or CHX disinfection.
- The ER group exhibited the highest bond strength values.
- CHX disinfection did not significantly alter bond strength in the ER group.
- The SE-CHX group displayed significantly lower bond strength compared to other groups.
- Adhesive failures were predominant in the SE-CHX group.
Takeaway
Using a mouthwash called chlorhexidine can help keep your teeth strong, but it might not work well with certain types of dental glue when fixing teeth.
Methodology
Class I cavities were prepared in extracted human teeth, treated with chlorhexidine or not, and restored with a universal adhesive. Microleakage and bond strength were assessed after thermal cycling.
Potential Biases
Potential bias due to the limited sample size and single adhesive type used.
Limitations
Only one adhesive was evaluated, which may limit the generalizability of the results.
Participant Demographics
Extracted human molar and premolar teeth without evidence of caries or cracks.
