  5. 4. The effect of calcium silicate-based cements on viability and differentiation of human stem cells from the dental apical papilla. : Future aspects in endodontic regeneration.

    University essay from Umeå universitet/Wallenberg centrum för molekylär medicin vid Umeå universitet (WCMM); Umeå universitet/Tandläkarutbildning

    Author : Lahood Abdalla; Bagir Soltani; [2023]
    Keywords : MTA; Biodentine; SCAP; Regenerativ endodonti; endodonti; traumatiserade tänder; tänder; unga tänder;

    Abstract : Introduction: Pulp necrosis in immature permanent teeth stops root development and may lead to higher risk of cervical fractures and a challenging treatment. Regenerative endodontic treatment (RET) aims to continue tooth development and implies the use of calcium silicate-based cements, such as Mineral trioxide aggregate (MTA) and Biodentine to seal the root canal.
