The aim of this study was to compare the efficacy of two irrigants on decreasing the pain and swelling at different times after treatment of necrotic pulp.
Fifty patients with single canal tooth and necrotic pulp were selected and divided into two groups, twenty-five in each. Rotary files were used for preparing the canals and 0.2% chlorhexidine gluconate and 2.5% sodium hypochlorite were used for irrigation of canals. Then canals were filled by lateral condensation technique. A questionnaire was given to patients asking for the level of their pain and swelling. The patients were followed for 48h. Visual Analogue Scale (VAS) was used for determination of pain degree. The scale with 4 levels was used for measurement of the intensity of swelling. The data were statistically analyzed using Mann-Witney and Kruskal-Wallis tests.
The research showed no significant difference between irrigant solutions in decreasing the amount of pain and swelling after endodontic treatments. No significant relationship was detected between the incidence of pain with swelling, age, and sex. Flare-up in maxilla was more than mandible.
According to results of this in vivo study it was concluded that efficacies of 0.2% chlorhexidine gluconate and 2.5% NaOCl are the same.
本研究的目的是比较两种冲洗剂在治疗坏死牙髓后不同时间减轻疼痛和肿胀的疗效。
选取50例单根管坏死牙髓患者，分为两组，每组25例。采用旋转锉预备根管，分别用0.2%葡萄糖酸氯己定和2.5%次氯酸钠冲洗根管。然后采用侧向加压技术充填根管。向患者发放问卷，询问其疼痛和肿胀程度。对患者进行48小时随访。采用视觉模拟评分法（VAS）确定疼痛程度。采用4级量表测量肿胀程度。数据采用Mann-Witney检验和Kruskal-Wallis检验进行统计学分析。
研究表明，根管冲洗剂在减轻牙髓治疗后疼痛和肿胀程度方面无显著差异。未发现疼痛与肿胀发生率、年龄和性别之间存在显著关系。上颌的急性发作比下颌更多。
根据本体内研究结果得出结论，0.2%葡萄糖酸氯己定和2.5%次氯酸钠的疗效相同。
