Insights

This study compared mouthwash antimicrobial activity. Chlorhexidine mouthwashes showed the highest effectiveness against tested bacteria and fungi, while miswak extract had low activity.

Area of Science:

  • Oral Microbiology
  • Pharmacology

Background:

  • Mouthrinses are widely used for oral hygiene.
  • Assessing their antimicrobial efficacy is crucial for clinical recommendations.

Purpose of the Study:

  • To evaluate the antimicrobial activity of eight commercial mouthrinses and a 50% miswak extract.
  • To compare their effectiveness against key oral microorganisms.

Main Methods:

  • The ditch plate method was employed to test antimicrobial activity.
  • Inhibition zones were measured for eight mouthrinses and miswak extract against seven microorganisms, including *Streptococcus spp.*, *Staphylococcus spp.*, and *Candida albicans*.

Main Results:

  • Mouthrinses containing chlorhexidine demonstrated the highest antibacterial activity.
  • Mouthrinses with cetylpyridinium chloride exhibited moderate activity.
  • The 50% miswak (Salvadora persica) extract showed low antimicrobial activity.

Conclusions:

  • Chlorhexidine-based mouthrinses are most effective among the tested products.
  • Further in vivo and in vitro studies, particularly using biofilm models, are recommended.
  • Dental professionals should guide patients in selecting effective mouthrinses.
