| Research Abstract |
The ideal healing of an endodontic treatment is a mineralized tissue formation on apical foramen. This study aimed at developing the new endodontic treatment which can heal by using Mineral Trioxide Aggregate(MTA) and S-PRG filler by controlling hard tissue formation of the cell which present in the periapical tissue. We used the cells that a human cementblast (HCEM), a human pulp chamber cell (HPulp) and a human periodontal ligament cell (HPLC). The co-culture with MTA and cement containing S-PRG filler. We investigated the expression of genes involved in mineralized tissue formation (Bone Sialoprotein ; BSP, Osteocalcin ; OCN), and mineralization (Alkaline phosphatase ; ALP).It was shown that BSP, OCN and ALP revelation become the maximum in 24 hours and as for all the cells, the potential of mineralized tissue ( bone or cementum) was observed. MTA and S-PRG filler promoting the differentiation induction of HCEM, HPulp, and HPLC participating in the mineralized tissue formation.
