Abstract

Insights

The root of the Salvadora persica tree (miswak) shows significant antimicrobial properties against common oral pathogens, supporting its use for preventing dental caries.

Area of Science:

  • Microbiology
  • Oral Health
  • Natural Products

Background:

  • Miswak (Salvadora persica) is a traditional, natural tooth-cleaning tool with known benefits for preventing dental caries.
  • Despite its historical use, miswak is not as widely adopted as other oral hygiene methods.
  • Scientific validation of miswak's antimicrobial efficacy against prevalent oral pathogens is needed.

Purpose of the Study:

  • To scientifically evaluate the in vitro antimicrobial effect of miswak against common oral pathogens.
  • To compare the antimicrobial activity of different parts and preparations of miswak.

Main Methods:

  • A cross-sectional study involving 100 healthcare workers was conducted.
  • Oral swabs were collected, and microorganisms were identified using standard bacteriological methods.
  • Four types of miswak (root and stem of Salvadora persica, stem of Azadirechta indica) were tested against Staphylococcus aureus, Streptococcus mutans, and Candida albicans using the agar diffusion method.

Main Results:

  • The root of the Salvadora persica tree (miswak), both packed and unpacked, demonstrated potent antimicrobial activity against all three tested microorganisms.
  • Miswak derived from the stem of the Salvadora persica tree and the stem of the Azadirechta indica tree showed no significant antimicrobial activity.

Conclusions:

  • Miswak derived from the root of the Salvadora persica tree exhibits significant antimicrobial activity against common oral pathogens.
  • This finding supports the potential of Salvadora persica root miswak as an effective oral hygiene tool for combating dental caries.
