Avulsion of permanent teeth in children resulting from trauma is an acute emergency presentation. When not adequately managed, it may result in functional and aesthetic disturbances, with implications for more complicated and prolonged treatment which require planning and biocompatibility in terms of forces used in moving the teeth orthodontically. Literature is scarce on a reported case of this nature and this is the first report in the literature in Nigeria.
We report on a case of avulsion of both maxillary central incisors in an 8-year-old male child of Sub-Saharan African ethnicity with sickle cell anaemia. One of the incisors produced by the parents was replanted at the clinic. The replanted tooth was later traumatized during the course of treatment which resulted in mobility and subsequent extraction of the tooth. At a later presentation at the clinic, orthodontic therapy was instituted. While orthodontic therapy has been considered to be completely noninvasive, special precautions should be taken in the clinical management of sickle cell anaemia patients to prevent local vaso-occlusive events.
The sequeale of traumatic avulsion in a medically compromised patient with sickle cell anaemia is presented. Prompt and early presentation for dental management is very important; while prevention and management of dental trauma should be recognized as a public health issue. Dental trauma in sickle cell anaemia can be minimized by practicing preventive measures with the use of mouth guard which is an effective device for preventing dental injuries, and patients should be advised to wear them during activities to prevent dental injuries.
儿童恒牙因外伤导致的牙脱位是一种急性紧急情况。若处理不当,可能会导致功能和美观问题,进而需要更复杂、更长期的治疗,这就需要在正畸移动牙齿时规划好所用的力并考虑生物相容性。关于此类报道的病例,文献资料很少,这是尼日利亚文献中的首例报道。
我们报告一例8岁撒哈拉以南非洲裔患有镰状细胞贫血的男童上颌中切牙双侧脱位的病例。家长找到的一颗脱位牙在诊所进行了再植。再植牙在治疗过程中后来又受到创伤,导致松动,随后被拔除。在诊所后来的一次就诊中,开始了正畸治疗。虽然正畸治疗被认为是完全无创的,但在镰状细胞贫血患者的临床管理中应采取特殊预防措施,以防止局部血管阻塞事件。
本文介绍了患有镰状细胞贫血的医学上有缺陷的患者因外伤导致牙脱位的后遗症。及时尽早进行牙科治疗非常重要;同时,应认识到预防和管理牙外伤是一个公共卫生问题。通过使用护齿器采取预防措施,可以将镰状细胞贫血患者的牙外伤降至最低,护齿器是预防牙损伤的有效装置,应建议患者在活动期间佩戴以防止牙损伤。
