Efficacy of Licorice Lollipops in Reducing Dental Caries in a Paediatric Population: A Systematic Review
Nuvvula, Sivakumar / Nunna, Mahesh / Almaz, Merve E. / Mallineni, Sreekanth K.
Purpose: To assess the efficacy of licorice lollipops in reducing dental caries in children.
Materials and Methods: A literature search was confined to the English language using MeSH terms congruent with PICO format in 'PubMed', 'Cochrane Library' and 'Ovid', covering the period from April 1967 to December 2017. Searches in Google Scholar, grey literature and hand search of cross-references were performed to find additional data. Suitable studies were selected based on the predefined inclusion and exclusion criteria. Quality analysis and risk of bias of the selected studies were performed using the Cochrane Collaboration's tool for risk of bias.
Results: Overall 519 articles were retrieved, 516 (electronic databases) and 3 (Google scholar). 516 publications were excluded due to non-availability of abstracts, or because they were unrelated studies, narrative reviews, and systematic reviews as well as letters to editors. Only three studies were included for final analysis. Quality analysis of these three studies showed that only one was of high quality, whereas the other two were rated as low.
Conclusion: Licorice lollipops showed a promising effect in reducing caries by decreasing Streptococcus mutans counts in the saliva. Further research using randomised controlled clinical trial (RCT) designs with large sample size are recommended.
