Abstract

Gingival disease refers to a group of pathological changes occurring in the gingival tissue, including inflammation of the gingiva and manifestations of systemic diseases in the gingiva. It can lead to inflammation of the supporting tissues of the teeth (gingiva, periodontal ligament, alveolar bone, and cementum), formation of periodontal pockets, progressive attachment loss, and alveolar bone resorption, eventually resulting in tooth loosening and loss. Tooth injury is one of the more common injuries encountered in forensic identification. The main imaging examination methods include periapical X-rays, panoramic radiographs, and CBCT (cone-beam computed tomography). Based on different imaging manifestations, the influence of varying degrees of periodontal disease on tooth injury is described, and viewpoints are proposed on the application of periodontal disease severity in forensic practice, with the aim of providing reference for fellow forensic examiners.
