Root fractures are uncommon following dental trauma but are mostly diagnosed shortly after the injury, although occasionally at routine dental appointments. This paper presents the management of the different types of root fractures and the types of healing response suggesting the appropriate follow-up of these injuries.
A thorough clinical examination supplemented with radiographs, vitality tests, appropriate treatment planning and subsequent follow-up of root fractured teeth can improve the prognosis for these teeth and also minimize the need for subsequent extractions. Immature teeth with root fractures have a better chance of healing compared to teeth with fully formed roots.
牙根折裂在牙外伤后并不常见，但大多在受伤后不久被诊断出来，不过偶尔也会在常规牙科检查时发现。本文介绍了不同类型牙根折裂的处理方法以及愈合反应类型，提示了对这些损伤进行适当随访的方式。
通过全面的临床检查，并辅以X光片、活力测试、恰当的治疗计划以及对牙根折裂牙齿的后续随访，可以改善这些牙齿的预后，同时尽量减少后续拔牙的必要性。与牙根完全形成的牙齿相比，牙根折裂的未成熟牙齿愈合的机会更大。
