The primers of Clearfil Protect Bond, Clearfil SE Bond, and Optibond Solo Self-etch demonstrated significant antibacterial properties against common oral bacteria. Adper Scotchbond 1 XT also showed some inhibition, suggesting potential benefits in reducing bacteria post-cavity preparation.
Area of Science:
- Dental Materials Science
- Antimicrobial Research
- Bacteriology
Background:
- Dental bonding agents are crucial for restorative procedures.
- Assessing their inherent antibacterial properties is vital for clinical efficacy.
- Understanding the antimicrobial potential of primers and adhesives informs material selection.
Purpose of the Study:
- To compare the antibacterial activity of five dental bonding agents against three oral bacteria.
- To evaluate primers, adhesives, and their combinations, including self-etch and total-etch systems.
- To benchmark against Chlorhexidine (2.5%) as a positive control.
Main Methods:
- Bacteria tested: Streptococcus mutans, Lactobacillus paracasei, Actinomyces naeslundii.
- Inhibition zones measured on agar plates after 48-hour incubation.
- Spectrophotometric analysis of bacterial growth inhibition at 600 nm for diluted suspensions.
Main Results:
- Clearfil Protect Bond primer inhibited all three bacteria; Clearfil SE Bond primer inhibited two species.
- Optibond Solo Self-etch primer showed significant inhibition against Actinomyces naeslundii.
- Adper Scotchbond 1 XT was the only cured product with significant inhibition, against Actinomyces naeslundii.
Conclusions:
- Primers from Clearfil Protect Bond, Clearfil SE Bond, and Optibond Solo Self-etch show promise for eliminating residual bacteria.
- Adper Scotchbond 1 XT may also contribute to bacterial reduction.
- Further investigation into the long-term antibacterial effects of these bonding agents is warranted.
