来源:华人健康网 | 发布时间:2010-11-25 11:47:56 | www.chinesejk.com

不可复性牙髓炎:不可复性牙髓炎按其临床经过特点,又分为:急性牙髓炎、慢性牙髓炎,逆行性牙髓炎

急性牙髓炎:急性牙髓炎临床表现是发病急、疼痛剧烈,临床所见急性牙髓炎(龋源性)大多是慢性牙髓炎急性发作。急性牙髓炎的剧烈的的疼痛的特点是自发性和阵发性痛,温度刺激的使重、疼痛常不能定位。疼痛常在夜间发作。急性牙髓炎的治疗应先急处理(开髓引流、安抚镇痛、药物镇痛),待症状缓解后再行牙髓病治疗。

慢性牙髓炎:牙髓炎的发生多为龋病所致,随着龋病的逐渐侵害,牙髓也就发生慢性炎症。慢性牙髓炎没有剧烈的自发痛,但有较长期的遇冷热刺激痛史,疼痛性质为胀痛。

逆行性牙髓炎:逆行性牙髓炎是牙周病患牙的牙周组织破坏后,感染通过侧、副根管或根尖孔进入牙髓引起的牙髓炎症。临床表现一般为急性炎症,为自发性和阵发性疼痛,对冷热刺激敏感或有放射性疼痛,治疗时则按急性牙髓炎处理。但亦可表现为慢性牙髓炎症状,则无明显自发痛,疼痛性质为胀痛,对冷热刺激敏感,则可按牙髓炎处理。
