In cases where permanent teeth have closed apices and completely erupted roots, the probability of root fractures is increased due to the stable support given by the adjacent bone and periodontal tissues. Fractures have the potential to affect several dental structures, including the pulp, dentin, cementum, bone, and periodontal tissues. In cases of horizontal root fractures (HRF), the apical section typically maintains vitality; however, the present case presented an unusual apex necrosis. Given the patient's age and tooth stability, traditional apical surgery was deemed inappropriate. Instead, a conservative treatment approach was chosen to preserve the tooth. This case report details the management and a 2-year follow-up of a maxillary central incisor exhibiting a HRF and apical necrosis, successfully addressed through the application of Mineral Trioxide Aggregate (MTA) in the both apical and coronal segments. Using MTA prevented apical surgery in cases of apex necrosis accompanied by HRF.
在恒牙根尖闭合且牙根完全萌出的情况下,由于相邻骨组织和牙周组织提供的稳定支撑,牙根骨折的概率会增加。骨折有可能影响多个牙齿结构,包括牙髓、牙本质、牙骨质、骨组织和牙周组织。在水平牙根骨折(HRF)的病例中,根尖部分通常保持活力;然而,本病例出现了不寻常的根尖坏死。考虑到患者的年龄和牙齿稳定性,传统的根尖手术被认为不合适。相反,选择了一种保守的治疗方法来保留牙齿。本病例报告详细介绍了一例上颌中切牙出现HRF和根尖坏死的治疗及2年随访情况,通过在根尖段和冠段应用三氧化矿物凝聚体(MTA)成功解决了该问题。在伴有HRF的根尖坏死病例中,使用MTA避免了根尖手术。
