Prevalence and Risk of Dental Erosion Linked to Carbonated Drinks in Adolescents: A Systematic Review and Meta-Analysis.

PURPOSE: To determine the prevalence of dental erosion due to carbonated beverage consumption among adolescents and the association between both variables through a systematic review and meta-analysis. METHODS AND MATERIALS: This study was conducted in accordance with the preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines for systematic reviews. A comprehensive literature search was performed in PubMed, Scopus, Web of Science, LILACS, and SciELO. Observational studies were included, and the PEO framework was used to identify dental erosion and non-erosion (outcome) and intake of carbonated beverages (exposure) in adolescents (population). The prevalence of dental erosion and odds ratio (OR) with 95% confidence interval (95%CI) to determine the risk of carbonated beverages were estimated with MedCalc V.23.0.2 and Review Manager (RevMan V.5.4.1) software, respectively. A P value 0.05 was considered to indicate statistical significance. RESULTS: A total of 24 studies met the eligibility criteria. The pooled sample included 21,541 adolescents, and the overall erosion prevalence was 37.6% (95%CI 26.3, 49.7%). The meta-analysis revealed a significant association between carbonated beverage consumption and dental erosion (OR = 1.98, 95%CI: 1.42-2.77; 7785 participants; I2 = 80%; P 0.0001). CONCLUSION: Dental erosion is a prevalent condition among adolescents, with a pooled prevalence of 37.6%. Carbonated beverage consumption among adolescents is associated with a 98% increased risk of dental erosion.
