Chalky teeth - can they be prevented?

Developmental defects of enamel (popularly termed "chalky teeth") are costly to patients and society. Many of these Developmental Dental Defects (DDDs = D3s) may become preventable if a better understanding of their causes and pathologies can be gained. Recently we assembled a multidisciplinary team to investigate the commonest D3, termed Molar Hypomineralisation, which manifests as soft and porous (chalky) enamel – worldwide, this congenital defect affects the two-year molars and/or six-year molars of 1-in-5 otherwise-healthy children, causing life-long risk of toothache, tooth breakdown and decay, and perhaps tooth loss in severe cases. Our initial proteomics investigation provided intriguing insights to the nature and possible cause of Molar Hypomineralisation, opening novel avenues for basic research and clinical developments. A novel detector for porous hydroxyapatite that has potential applications in preventive and restorative dentistry arose from this work.
