The combination of two or more different types of traumatic dental injuries occurring concurrently to the same tooth presents a significant clinical challenge. By focusing on a rare combination of injuries, this case study explores the issues of delayed management of root fractures accompanied by coronal extrusions in immature maxillary permanent central incisors, underscoring the necessity for tailored approaches when guidelines for intervention were unmet. The case involves an eight-year-old boy who delayed seeking care for approximately a year after suffering trauma to his upper front teeth in a fall accident at school. The clinical examination revealed partial displacement of two maxillary central incisors in an incisal direction, resulting in increased mobility. Radiographs further showed horizontal root fractures in the apical third of both extruded incisors. Encouragingly, the injured teeth exhibited a normal response to electric pulp testing without signs or symptoms of pulpal pathology, suggesting pulp vitality and eliminating the need for root canal treatment. The extruded coronal fragments were repositioned orthodontically using a utility arch. At the 14-month follow-up, the affected incisors were clinically asymptomatic, functionally satisfactory, and esthetically pleasing. Conservative orthodontic management of extrusive luxation concomitant with root fracture in immature permanent teeth may prove effective in select cases, particularly when long-term follow-up and proper oral care are maintained.
同一颗牙齿同时发生两种或更多不同类型的外伤性牙损伤给临床带来了重大挑战。通过关注一种罕见的损伤组合,本病例研究探讨了未成熟上颌恒中切牙根折伴牙冠移位延迟处理的问题,强调了在干预指南未得到满足时采取定制方法的必要性。该病例涉及一名8岁男孩,他在学校摔倒事故中上前牙受伤后大约一年才延迟就医。临床检查发现两颗上颌中切牙向切方部分移位,导致松动度增加。X线片进一步显示两颗移位切牙根尖三分之一处有水平根折。令人鼓舞的是,受伤牙齿对牙髓电测试表现出正常反应,没有牙髓病变的体征或症状,表明牙髓活力正常,无需进行根管治疗。使用功能弓对移位的牙冠碎片进行了正畸复位。在14个月的随访中,患牙临床无症状,功能满意,美观效果良好。在未成熟恒牙中,对于伴有根折的牙冠移位进行保守正畸治疗在某些情况下可能是有效的,特别是在保持长期随访和适当口腔护理的情况下。
