In pulp regeneration, the endodontist uses nanofiber-based material along with stem cells obtained from your child's own pulp or bone marrow to build a foundation upon which the tooth can regenerate.1 The platform also supports the regulated release of growth factors to promote pulp regeneration as well as the controlled delivery of antibiotics to aid in the elimination of infection. Endodontic therapy is a form of treatment that entails removing contaminated tissue from teeth with necrotic pulp and replacing it with an inert substance. The predictability and dependability of this treatment have long been established.
