Symbiotic effect of L-arginine plus Lactobacillus rhamnosus GG on the growth of cariogenic Streptcoccus mutans in people with dental wear due to the consumption of soft drinks

Abstract:

The high prevalence of erosive dental wear caused by the frequent ingestion of soft drinks has become one of the main oral health problems in children, adolescents and young adults, whose treatment becomes a challenge for health professionals. The research aimed to evaluate the exogenous erosive effect of soft drinks on dental tissue through the in vitro thermocycling process, in which 50 extracted premolars were subjected to the experience of exposure to a soft drink, under experimental conditions, resulting in a significant difference between the initial pre-thermocycling weight in each piece and the final weight obtained after the process, which demonstrates the negative effect of the consumption of soft drinks. In that same sense, and as part of this research, the beneficial effects of probiotics such as L-alanine were evaluated as a supplement for beneficial bacteria for oral health such as Lactobalilos rhamnosus GG, which manage to stop the advance of pathogenic and opportunistic bacteria such as Streptococcus mutans. The results showed that as the concentration of the probiotic increases, the decrease in the number of colony-forming units and biofilms of Streptococcus mutans is greater. In addition, the research addresses the perception of risk in students, of ingestion of soft drinks in dental erosion and the criteria that their tutor teachers have on the subject.
