Severe burn injuries are among the most traumatic and physically debilitating conditions, impacting nearly every organ system and resulting in considerable morbidity and mortality. Given their complexity and the involvement of multiple organs, various animal models have been created to replicate different facets of burn injury. Methods used to produce burned surfaces vary among experimental animal models. This study describes a simple, cost-effective, and user-friendly mouse burn model for creating consistent full-thickness burns using a digital heating device. The tip of this device was applied to the dorsum of mice for 10 s at 97 °C to establish a chessboard-like burn and examine wound healing under the treatment of an experimental dressing. Skin samples were collected for histological analysis, including Hematoxylin and Eosin (H&E) staining and Masson's staining. Wound healing was assessed through analysis of the wound area and microscopic examination of inflammatory infiltration, re-epithelialization, and granulation tissue formation. The mouse burn injury model can serve as a fundamental tool in studying the pathophysiology of thermal injuries and evaluating therapeutic interventions.
