混合牙列期中,处于牙根形成期的第一恒磨牙常因龋病累及牙髓;恒前牙可因外伤造成牙髓损伤。因此,牙根发育完成之前,对损伤牙髓进行适当的治疗,促使牙根继续发育或根尖形成具有相当重要的临床价值。本文就混合牙列期牙根发育阶段,牙髓病的处理原则加以简要综述。一、保存生活牙髓的盖髓术损伤活髓的处理,存在着两种截然不同的看法。一种以牙髓愈合的可能性低,损伤的活髓将死亡为前题,主张以外科法去除受伤的活髓,或以“化学”药物毁坏牙髓而保
In the mixed dentition period, the first permanent molars at the period of root formation often involve the dental pulp due to dental caries. The permanent anterior teeth may cause dental pulp injury due to trauma. Therefore, the development of the root before the completion of proper treatment of damaged pulp, prompting root continued to develop or root tip formation has a very important clinical value. This article summarizes the treatment principles of mixed pulp dentition during the period of root development and endodontics. First, the preservation of living pulp pulp damage to the treatment of viable pulp, there are two completely different view. A low possibility of dental pulp healing, the injury of the living marrow will be the death of the former title, advocating the surgical removal of injured vital marrow, or “chemical” drugs to protect the pulp and Paul
