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.

Insulin Glargine

Clinical and translational studies support its use as a basal comparator because of prolonged absorption and stable glycemic control. It is heavily used in basal-bolus regimen research and insulin-delivery optimization studies.
