Objective: The aim of this article is to review the published literature with the purpose of knowing the importance of using various probiotic Streptococcus strains as a preventive and therapeutic method for dental caries management. Materials and Methods: Research question was formulated based on the PICO strategy. A comprehensive electronic literature search was conducted across PubMed/Medline, Scopus, and EBSCOhost databases independently by two reviewers. All papers published from 1989 to December 2017 that focused on the use of probiotic Streptococcus strains for caries prevention were included in this review. Inclusion and exclusion criteria were applied to the selected articles, and a customized data extraction sheet was formulated. The selected articles were subjected to quality assessment, and the risk of bias in selected studies was evaluated. Results: A total of five articles were included. The overall risk of bias of the selected clinical trials was found to be high risk, and the overall level of evidence of the selected in vitro studies was moderate. Conclusion: The two included clinical studies on the use of probiotic Streptococcus strains for caries prevention had high risk of bias. Although in-vitro studies showed promising results, clinical studies have not demonstrated clear clinical outcomes. Thus, there is a vast scope for future research in this field. Clinical Relevance: Application of oral probiotics will help reinstate a balanced microbiota and thereby improving oral health. This systematic review focused on evaluating the role played by probiotic Streptococcus strains in the carious lesion incidence.
