Due to the close proximity of the primary teeth with the developing permanent successors, several developmental alterations in the permanent successors have been reported as consequences of traumatic dental injuries to the primary dentition. When they occur at a very young age such trauma could disturb normal tooth development and cause rare anomalies, including sequestration of the permanent tooth germ and odontoma-like malformations. A literature review of case reports with a history of trauma and odontoma formation is discussed in this paper. This paper also includes a case report of a patient, who was 3-years and 5-months old, when she was seen at the University of California, Los Angeles Children's Dental Center for the first time. The grandmother reported that the child was dropped from the father's lap when she was 2 weeks old and suffered head trauma and multiple skull fractures.
由于乳前牙与正在发育的恒牙位置非常接近，因此有报道称，乳前牙外伤可导致恒牙发生多种发育异常。如果这种创伤发生在非常年幼的时候，可能会干扰正常的牙齿发育，并导致罕见的异常，包括恒牙胚的隔离和类似于牙瘤的畸形。本文讨论了一份伴有外伤和牙瘤形成病史的病例报告文献综述。本文还包括了一位患者的病例报告，她在 3 岁零 5 个月大时首次到加利福尼亚大学洛杉矶分校儿童牙科中心就诊。祖母报告说，孩子在 2 周大时从父亲腿上摔下，头部受伤并多处颅骨骨折。
