Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Silica calcium phosphate (often referred to as calcium phosphate with added silica or sometimes as tricalcium phosphate with silica) is used in dental applications primarily for its ability to support tooth remineralization and repair. The scientific rationale is based on the role of calcium and phosphate ions in the formation and maintenance of hydroxyapatite, the mineral component of tooth enamel and dentin. Silica, meanwhile, can act as a nucleating agent, facilitating the deposition of hydroxyapatite and enhancing remineralization. Several in vitro and in vivo studies have demonstrated that calcium phosphate-based compounds, especially when combined with small amounts of silica, can promote the deposition of new mineral on demineralized tooth surfaces, potentially aiding in the repair of early carious lesions and strengthening enamel. However, most clinical studies focus on bioactive glass (a specific form of silica-containing calcium phosphate) rather than generic "silica calcium phosphate." Evidence from these studies suggests moderate effectiveness in remineralization, but the quality of clinical data varies, and long-term benefits in preventing cavities or restoring enamel are still under investigation. Therefore, while there is scientific support for the use of silica-calcium phosphate compounds in dental care, especially in remineralization products, the evidence is not overwhelmingly robust and is rated as moderate (3/5).
