Comparative evaluation of two remineralizing agents in limiting dental erosion

Introduction: Enamel erosions are becoming increasingly important for long term dental health and have been associated with acidic attacks caused by consumption of beverages. Dental health care community has sought effective remineralizing agents to combat deleterious effects of carbonated drinks with acidic content. Methods: In-vitro study of remineralization potential of CPP-ACPF and β-TCP was evaluated on human enamel sections with one control group (Gp I) and two experimental groups (Gp II and III, n=15 in all three groups). Specimens of groups II and III were treated with CPP-ACPF and β-TCP respectively for protective remineralization over 28 days. Thereafter specimens of all three groups were subjected to a simulated acid attack by a cola-based beverage over a period of 4 days. Energy Dispersive X-ray Analysis (EDAX) was used in pre and post experimental stages to evaluate elemental mineral content of enamel. One way ANOVA was used to evaluate results. Results: Both agents resulted in remineralization and protection against acid demineralization. β?TCP was found to provide better remineralization and protection from acid attack than CPP-ACPF. The difference in both findings was statistically significant (p=
