Acute pain and swelling following endodontic treatment are a challenge for both the patient and the dentist. According to previous studies, the incidence of flare-ups increases after endodontic treatment of teeth with necrotic pulps. Calcium hydroxide is currently used as a multi-purpose drug in root canal therapy. The aim of this study was to evaluate the incidence and severity of flare-ups after treatment of pulpless teeth using calcium hydroxide as an intracanal dressing. Sixty patients with single-root necrotic teeth participated in this study. These patients were randomly divided into three groups of 20. The patients were treated in Group A in a single-visit approach, in group B with a two-visit approach without any intracanal dressing and group C with a two-visit approach using calcium hydroxide as an intracanal dressing for one week. All of the patients were followed for 72 hours after each treatment session. The information about the incidence and severity of pain and swelling was recorded in tables, using a modified Visual Analogue Scale for pain severity measurement and a scale with four degrees for measuring the severity of swelling. The data were analyzed by chi-square test and GENMODE procedure.
根管治疗后的急性疼痛和肿胀对患者和牙医来说都是一项挑战。根据以往的研究，牙髓坏死的牙齿在根管治疗后疼痛发作的发生率会增加。氢氧化钙目前在根管治疗中用作多功能药物。本研究的目的是评估使用氢氧化钙作为根管内封药治疗无髓牙后疼痛发作的发生率和严重程度。60名单根坏死牙患者参与了本研究。这些患者被随机分为三组，每组20人。A组患者采用一次性就诊治疗，B组患者采用两次就诊治疗且不进行任何根管内封药，C组患者采用两次就诊治疗，使用氢氧化钙作为根管内封药一周。每次治疗后对所有患者进行72小时随访。使用改良的视觉模拟量表测量疼痛严重程度，并使用四度量表测量肿胀严重程度，将疼痛和肿胀的发生率及严重程度信息记录在表格中。数据采用卡方检验和GENMODE程序进行分析。
