Research Overview
P11-4
P11-4 has been studied for its ability to penetrate initial carious lesions and self-assemble into a fibrillar matrix that nucleates hydroxyapatite. Human and preclinical studies support its role in non-invasive enamel repair.
Calcitonin
Calcitonin has been evaluated in randomized trials and reviews for pain associated with vertebral compression fractures and other bone-related conditions. The signal is strongest for short-term analgesia rather than long-term chronic pain control.
