The purpose of this work was to evaluate the physicochemical properties, the cytotoxicity and in vivo biocompatibility of MTA Repair HP (MTA HP) and White MTA (WMTA). The setting time, flow, radiopacity and water solubility were assessed. To the cytotoxicity assay, primary human osteoblast cells were exposed to several dilutions of both materials eluates.

Materials And Methods: Discs of each material (n = 30) were exposed to phosphate buffered saline (pH = 7.4) or butyric acid (pH = 5.
Article Synopsis
- The study aimed to investigate how various bleaching products affect the diffusion of hydrogen peroxide (HP) and their biological effects on human dental pulp stem cells (DPSCs).
- Different exposure times of the bleaching gel (15, 30, and 90 minutes) were tested on enamel/dentine discs, and the effects on cell viability, migration, and morphology were assessed.
- Results showed significant reductions in cell viability, especially with shorter exposure durations, while DPSCs preserved their stem cell characteristics despite exposure to varying bleaching agents.
Objective: To evaluate the in vitro cytotoxicity of Equia Forte (GC, Tokyo, Japan) and Ionostar Molar (Voco, Cuxhaven, Germany) on human dental pulp stem cells (hDPSCs).
Methods: hDPSCs isolated from third molars were exposed to several dilutions of Equia Forte and Ionostar Molar eluates (1/1, 1/2 and 1/4). These eluates were obtained by storing material samples in respective cell culture medium for 24h (n=40).
Introduction: The aim of the present study was to evaluate the in vitro cytotoxicity of MTA Repair HP, NeoMTA Plus, and Biodentine, new bioactive materials used for dental pulp capping, on human dental pulp stem cells (hDPSCs).
Methods: Biological testing was carried out in vitro on hDPSCs. Cell viability and cell migration assays were performed using eluates of each capping material.
Introduction: The aim of the present study was to evaluate the in vitro cytotoxicity of endodontic sealers (GuttaFlow Bioseal, GuttaFlow2, and MTA Fillapex) on human periodontal ligament stem cells (hPDLSCs). As a reference, AH Plus was compared with the more recent endodontic sealers regarding cell viability and cell attachment.
Methods: Biological testing was carried out in vitro on hPDLSCs.
