Root fractures are defined as injuries involving dentine, cementum, and the pulp. They are rare, and they account for 0.5-7% of the dental injuries in the permanent teeth. Root fractures may be the result of direct trauma to the teeth or indirect trauma to the oral cavity. Their incidence is highest in the group of adolescent patients aged 11 to 20 years. The purpose of the paper is to review the literature supported by a case series with three different types of root fractures with various healing patterns, though all with successful long-term treatment outcomes. All presented patients were boys aged 10 to 11 years. Root fractures occurred as a result of direct impact with the teeth by an object. Only one boy had his root-fractured teeth endodontically treated. However, one of the teeth was misdiagnosed with pulp necrosis, and the other became non-vital after additional trauma. Root fractures in young patients have good healing potential. Appropriate and early diagnostic and therapeutic procedures for treating root-fractured teeth are necessary to achieve favorable healing and a good long-term prognosis. Regardless of the pattern of healing of fractured roots and the treatment provided, patients require long-term follow-up and the need to plan a management strategy in case complications occur. Failure of the healing of fractured root is a worst-case scenario, especially in patients of developmental age. In such cases, the primary goal of treatment is to preserve the alveolar ridge until growth is complete.
根折是指涉及牙本质、牙骨质和牙髓的损伤。它们较为罕见，占恒牙牙外伤的0.5%-7%。根折可能是牙齿直接受外伤或口腔间接受外伤所致。其发病率在11至20岁的青少年患者组中最高。本文的目的是回顾一系列病例所支持的文献，这些病例包含三种不同类型的根折，具有不同的愈合模式，但均获得了成功的长期治疗结果。所有呈现的患者均为10至11岁的男孩。根折是由物体直接撞击牙齿导致的。只有一名男孩对其根折牙齿进行了根管治疗。然而，其中一颗牙齿被误诊为牙髓坏死，另一颗在再次受伤后牙髓失去活力。年轻患者的根折具有良好的愈合潜力。为实现良好的愈合和长期预后，对根折牙齿进行适当且早期的诊断和治疗程序是必要的。无论根折的愈合模式及所提供的治疗如何，患者都需要长期随访，并且需要制定管理策略以防并发症发生。根折愈合失败是最坏的情况，尤其是在发育年龄的患者中。在这种情况下，治疗的主要目标是在生长完成前保留牙槽嵴。
