Summary
Introduction:
This text discusses a study examining the effects of various electronic cigarette (ECIG) flavors on the growth of common oral commensal bacteria. The study compares the impact of ECIG-generated aerosols and E-liquids with and without flavorings on the growth of four common strains of oral bacteria.
Key Points:
* The study used four common strains of oral commensal bacteria: Streptococcus gordonii, Streptococcus intermedius, Streptococcus mitis, and Streptococcus oralis.
* The ECIG flavors tested included tobacco, menthol, cinnamon, strawberry, and blueberry.
* The study found that concentrated flavorings were toxic to oral bacteria, but 5% flavorings in E-liquid had no effect.
* ECIG-generated aerosols had no effect on bacterial growth when exposed to 100 puffs or an equivalent amount of E-liquid.
* however, when exposed to higher concentrations of E-liquid flavorings, dose-dependent inhibition of growth was observed.
* The study suggests that ECIG flavors may alter the growth of oral commensal bacteria, which could have implications for oral health.
* The study highlights the need for further research on the safety of ECIG flavors and their potential impact on oral health.
Main Message:
The study's main message is that ECIG flavors, particularly at higher concentrations, can alter the growth of oral commensal bacteria. This finding has implications for oral health and emphasizes the need for further research on the safety of ECIG flavors. It is important for regulators to consider the potential risks associated with ECIG flavors and take appropriate action to protect public health.
