Saliva pH and Enamel Remineralisation: Exploring a Potential Contributor to Dental Caries
CWSF · 2026 Health & Wellness
Overview
This project studied how different salivary acidity levels similar to that of males (neutral) and females (acidic) affect tooth enamel by quantifying structural damage and recovery over time. Samples were first damaged to simulate early tooth decay, then placed in two conditions: a more acidic environment (pH 6.2) and a neutral one (pH 7.2). By tracking changes in mass and using light refraction patterns to observe internal damage, it was found that the acidic group consistently lost mass, showing ongoing damage, while the neutral group showed less damage, suggesting a pattern of repair. This knowledge is significant to dentistry and public health because it helps explain how everyday factors like diet, predetermined gender-based physiological conditions and oral care products can influence tooth health and the early stages of cavities.
