Abstract
ObjectivesWound healing of the oral mucosal epithelium through the application of far infrared radiation emitted by isotropic high-density carbon was investigated in order to clarify the preventive and therapeutic effects of isotropic high-density carbon on oral mucosal injury. Materials and methodsA carbon massager with an isotropic high-density carbon tip was used. Far infrared radiation was applied to the human buccal mucosal squamous cell carcinoma cell line, HO-1-N-1 using a carbon massager, and cell growth factors and heat shock protein levels were measured using real-time RT-PCR and ELISA. Far infrared radiation was applied to oral mucosal injury in SD rats over time using the carbon massager, and its effects were examined by HE staining and immunostaining. The immunostaining positive rate was measured and analyzed using image analysis software. ResultsFar infrared radiation induced stronger mRNA expression and higher HSP27 and HSP70 protein levels on real-time RT-PCR and ELISA than in the control group. The far infrared radiation of oral mucosal injury in rats induced strong positive reactions, and positive rates for Ki67, HSP27, and HSP70 were higher than those in the control group. ConclusionsThe treatment of oral mucosal injury with far infrared radiation emitted by isotropic high-density carbon appears to have promoted heat shock protein production and induced regenerative reactions more strongly than in the control group.
