Evaluation in vitro of cytotoxicity of dentin desensitizers on human gingival fibroblasts.
The purpose of this study is to compare the cytotoxic effect of three materials, which have been used for treating dental hypersensitivity. Material and method: In vitro study. Clinpro (3M Co, St. Paul, MN. USA), Seal & Protect (Dentsply, DeTrey GmbH. Germany) and UltraEZ (Ultradent Products, I...

Clinpro (3M Co, St. Paul, MN. USA), Seal & Protect (Dentsply, DeTrey GmbH. Germany) and UltraEZ (Ultradent Products, Inc., S. South Jordan UT.

Statistical significance was set at 5%. Results: Seal & Protect and Clinpro were found to be highly toxic at 24 and 48 hours, reaching 70% toxicity at concentrations over 0.01g/ml. Seal & Protect and Clinpro polymerized disks were toxic at 24 and 48 hours. UltraEZ showed an increased between 46% and 67% in cell viability at 24 hours and between 8% and 45% at 48 hours. Statistical analysis showed differences between these three desensitizers when comparing concentration and control group (p<0.05). Discussion: UltraEZ did not have a cytotoxic effect and may be considered a compatible and safe material, whereas polymerized and non-polymerized Clinpro and Seal & Protect should be used with caution.http://www.joralres.com/index.php/JOR/article/view/joralres.2015.005/119Dentin Desensitizing AgentsCytotoxicityHuman Gingival FibroblastsDentin Sensitivity |
