| Summary: | Introduction: Chrysanthemum rubellum (durian) flower (CR) is well-known for its usefulness in conventional and advanced medicine. Bioactive glass properties are geared towards hard tissue regeneration. Hence, this study aims to investigate the response of dental pulp stem cells (DPSC) when exposed to bioactive glass-chrysanthemum flower extract-conditioned medium. Methods: Chrysanthemum rubellum (durian) yellow coloured petals freeze dried extracts (CRE) was prepared by separation and agitation in distilled water where the final powdery compound was being investigated and combined with melt-derived BG 45S5 powder to produce BGCRE-conditioned medium. The CRE extracts in various concentrations and BGCRE-conditioned medium were exposed to DPSC and the cells responses were assessed using AB and MTT assays. The CRE and BGCRE-conditioned media were also assessed using ICP-OES to check for ionic release profile from both medium. Results: The CRE-conditioned medium (7.81, 15.63, 31.25 and 62.5 μg/ml) showed a dose-dependent effect towards DPSC from Days 1 until 14. The BGCRE-conditioned medium containing BG powders (1 mg/ml) with the lower amount of CRE extracts (0.02 and 0.1 mg/ml) promoted DPSC viability and proliferation rate from Days 1 until 14 based on AB and MTT assays. The BGCRE-conditioned medium has potentially affected the DPSC viability and proliferation. Conclusion: The presence of CRE in BGCRE-conditioned medium enhanced the DPSC viability and proliferation possibly through the combined effect of CRE and BG. This BGCRE combination showed potential as natural medicament for dental tissue regeneration. © 2019 UPM Press. All rights reserved.
