Hypothesis
Does chlorhexidine varnish effectively reduce the counts of Streptococcus mutans and Porphyromonas gingivalis in patients undergoing orthodontic treatment?
Conclusion
Chlorhexidine varnishes can significantly reduce harmful bacteria and improve oral health without the side effects of traditional mouth rinses.
Supporting Evidence
- Chlorhexidine varnish significantly reduced S. mutans counts at 1 month.
- There was a significant reduction in P. gingivalis counts at both 1 and 3 months.
- The varnish did not cause the side effects associated with mouth rinses.
Takeaway
This study shows that a special varnish can help keep your mouth healthy by reducing bad bacteria that cause cavities and gum problems.
Methodology
A split-mouth technique was used with 30 patients, applying chlorhexidine varnish to one side and a placebo to the other, measuring bacterial counts at baseline, 1 month, and 3 months.
Limitations
The effectiveness of the varnish on S. mutans decreased by the end of 3 months.
Participant Demographics
Patients undergoing orthodontic treatment.
