Bilirubin induces discoloration and hypodontia on tooth
Background
Systematic and local factors give various effects to teeth during odontogenesis or after eruption. Discoloration of teeth is also caused by systematic and local factors and sometimes leads to esthetic and biological problems. Bilirubin is the product of heme metabolism and causes greenish discoloration and hypodontia with its high concentration in blood.
Objective
This review aimed to indicate effects of bilirubin on odontogenesis with in vitro model established by stem cells of human exfoliated deciduous teeth (SHED).
Results
Recent studies showed that bilirubin suppressed cell proliferation and promoted cell death in SHED with alteration of their involved-signaling pathways. In addition, it was indicated that pamidronate recovered bilirubin-altered signaling pathways and bilirubin-impaired dentinogenic function of SHED.
Conclusion
SHED could be tool to established human in vitro model to elucidate human pathogenesis and for screening to pick up the candidates of medicines.
