Fluoride has the potential to inhibit caries by promoting remineralisation of carious lesions and acid eroded enamel. The presence of fluoride in the mouth in a sustained low level is considered to be the most effective method in dental prophylaxis and fighting caries. Therefore, some commercial polymeric dental restorative materials aim to release fluoride at the tooth surface. The major drawback with these materials is the inability to replenish their fluoride store, thus leaving them devoid of fluoride after a short period of time; they do not have the ability to recharge once they have released their fluoride content.
This project is based on developing novel and experimental polymeric dental materials, acting as fluoride rechargeable systems, with the incorporation of layered double hydroxides (LDHs). LDH consists of positively charged inorganic matrices, arranged in sheets, counterbalanced with the intercalation of anions within those hydrated interlayers. LDHs have proven to be successful in removal of excess fluoride from drinking water; they are also utilised in the controlled release of pharmacologically active compounds. The success of these LDH fluoride battery systems will have a huge impact in the dental field in fighting caries, the number one cause of tooth failure. The outcome of this project should lead to product(s) approaching the marketing stage.
• To synthesise and incorporate LDHs into a variety of commercial and experimental polymeric dental materials and to test their ability to act as rechargeable fluoride systems, maintaining an optimal low level of fluoride necessary in the mouth.
• To study the physicomechanical properties of these materials before and after releasing fluoride, after recharging and re-releasing fluoride.
