Effect of Green Tea Extract versus Casein Phosphopeptide -Amorphous Calcium Phosphate on Treatment of Dental Erosion of Primary Teeth Enamel: An In Vitro Study

Abstract

Dental erosion is the situation of a chronic loss of dental hard tissue that is chemically etched away from the tooth surface by acids without bacterial involvement. Acid of intrinsic (gastrointestinal) and extrinsic (dietary and environmental) origins are the main etiologic factors for dental erosion. Over the last decades, there has been a significant worldwide increase in the consumption of acidic beverages, such as soft drinks and ready-to-use fruit juices which caused increase in the prevalence of dental erosion all over the world. The aim of this study was to analyze the impact of green tea extract versus CPP-ACPF on treatment of enamel erosion in primary teeth through microhardness testing and scanning electron microscope analysis. Fifty two enamel specimens were prepared from freshly extracted or exfoliated human primary molar teeth. The crowns were embedded in acrylic resin with the labial or lingual enamel surface exposed. Enamel surfaces were ground flat using wet water proof fine silicon-carbide abrasive paper.
