当机体受到外力的作用,导致器官组织的完整性遭受破坏或功能障碍,均称为损伤。口腔颌面部是人体的暴露部分之一,因此,较易发生损伤。口腔颌面部损伤的发生率文献报道不一。Kramer 报道1.5~3.5%的儿童可发生口腔颌面部损伤;Hargraves(1970)报道儿童中6%左右前牙损伤需要积极治疗;早期研究发现口腔损伤占4~14%。
When the body is subjected to external forces, resulting in the destruction of the integrity of the organ tissue or dysfunction, are called damage. Oral and maxillofacial region is one of the exposed parts of the body, therefore, more prone to damage. The incidence of oral and maxillofacial injury in the literature reported different. Kramer reports that oral and maxillofacial injuries occur in 1.5-3.5% of children; Hargraves (1970) reported aggressive treatment of about 6% of anterior teeth injuries in children; early studies found that oral injuries account for 4-14%.
