... The efficacy of postnatal interventions in expectant mothers for preventing dental caries and MS transmission in their children has been thoroughly studied18; however, data regarding the efficacy of prenatal interventions remain unclear. Therefore, the purpose of this paper was to provide a systematic review of the current literature assessing the efficacy of maternal administration of fluoride, chlorhexidine mouthrinses, and xylitol in altering the mutans streptococci levels in children.
Introduction
Environmental neurotoxicants are pollutants that can negatively affect many cellular metabolic-processes through different pathways: neuroendocrine/thyroid hormone disruption (Pb, methyl-Hg, organochlorines, and polychlorinated biphenyls-PCB), oxidative stress (Pb, methyl-Hg, organochlorines, and chlorpyrifos), dopamine dysfunction (Pb, methyl-Hg, As, chlorpyrifos, pyrethroids, and organochlorines) (Heyer and Meredith, 2017; Rock and Patisaul, 2018).

1. Introduction
Fluoride is widespread and unevenly distributed in the environment, and it can be rapidly absorbed into the body via water, food, and air (Johnston and Strobel, 2020). Fluoride consumption at the prescribed level is essential for human health, whereas excessive fluoride exposure is harmful to health. Groundwater, minerals, soil, household chemical products such as varnishes, gels, mouthwashes, and toothpaste are significant sources of fluoride exposure. Others include industrial
7.2. Toothpaste
The effects of toothpaste on the oral microbiota have been investigated more thoroughly than the effects of toothbrushes. In the same study as previously described,33 the researchers also compared the oral and toothbrush microbiotas of participants who used either traditional Chinese medicine toothpaste or antibacterial toothpaste. While both types of toothpaste effectively reduced the numbers of a selection of pathogenic bacteria, they also suppressed oral S salivarius and L
