根管治疗的目的在于清除根管内坏死的牙髓组织,利用根管充填剂的持续消毒作用,去除根管内容物对根尖周组织的不良刺激,促进根尖周病变的愈合。氧化锌糊剂是目前广泛应用的根管充填糊剂,但由于术后反应较大,且物理性能较差。本文选择260例根尖周病患者,随机分别用碧兰麻和氧化锌糊剂充填根管并进行临床疗效对比。1资料与方法1.1临床资料选取我院口腔内科门诊260例根尖周炎的患者,男110例,女150例,年龄15～72岁。将观察对象随机分成实验组130例;对照组130例。要求患者无牙周病,无根
The purpose of root canal therapy is to remove the necrotic pulp tissue of the root canal and to use the continuous disinfection of the root canal filling agent to remove the adverse stimulus to the periapical tissue by the contents of the root canal and promote the healing of periapical lesions. Zinc oxide paste is currently widely used root canal filling paste, but due to large postoperative reaction, and poor physical properties. In this paper, 260 patients with periapical periodopathy were selected and randomized respectively to fill the canal with pennilefine and zinc oxide paste and compare the clinical curative effect. 1 Materials and Methods 1.1 Clinical data selected from our hospital oral cavity outpatient 260 cases of periapical patients, 110 males and 150 females, aged 15 to 72 years. Subjects were randomly divided into experimental group of 130 cases; control group of 130 cases. Patients without periodontal disease, no root
