Potential effects of Psidium sp., Mangifera sp., Mentha sp. and its mixture (PEM) in reducing bacterial populations in biofilms, adherence and acid production of S. sanguinis and S. mutans

Virulence traits-based behavior of Streptococcus mutans bacteria from dental plaque and dental caries conditions

“…An important virulence trait of S. mutans is its ability to metabolize a variety of dietary carbohydrates such as sucrose and produce a large amount of acid by fermentation; thus, the isolates were able to drop the suspension pH from 7 to 3 to become acidic during the test three hours (Figure 1). There was a statistically significant difference in the ability of S. mutans to lower the suspension pH among the three test groups of isolates (Figures 2 -5) (p < 0.0001), which was consistent with the results of other studies (Napimoga et al 2004;Baker et al 2017;Valdez et al 2017;Shafiei et al 2020). However, comparing the acidogenicity among S. mutans isolates from the three groups revealed significant differences in their ability to reduce the pH (p < 0.0001) which did not agree with the results of Napimoga et al (2004) and this difference may be because the samples were taken from the saliva, not from plaque or caries lesion conditions as in this study.…”

Comparison of the Antibacterial Activity of the Ethanol Extract vs Hydroalcoholic Extract of the Leaves of Mangifera indica L. (Mango) in Different Concentrations: An In Vitro Study

“…This biofilm can prolong the time of colonization and infection, as well as the dispersion to different parts of the human body. 4,5,7 Infections develop from the deepening of this bacterium by a solution of tissue continuity due to trauma, skin or surgical lesions. These infections generate purulent material forming abscesses and can cause minor infections of the skin and soft tissues and invasive infections such as: infections of the central nervous system, respiratory, gastrointestinal and urinary tract, bacteraemia and osteomyelitis.…”

“…Since it is not possible to use first-line antibiotics, it is necessary to use more expensive medicines, which increases the costs for the family and society. [5][6][7][8] In health sciences, for example, the use of antibiotics is justified in the presence of odontogenic infections and as prophylaxis in at-risk patients. Among stomatological infections, bacteremia and osteomyelitis are common as a result of invasive dental procedures whose multifactorial origin includes a very varied microflora, finding opportunistic microorganisms such as S. aureus, which is related to the onset of these diseases.…”

Nanotechnologies: An Innovative Tool to Release Natural Extracts with Antimicrobial Properties

“…Moreover, the extracts of Psidium sp., Mangifera sp., and Mentha sp. and its mixtures displayed antimicrobial effects and strongly reduced Streptococcus mutans [37].…”
