结局指标
主要结局
measuring patients postoperative pain and swelling following endodontic re-treatment sessions using Categorical (4 points) unit using questionnaire.
时间窗: 7 days between the 2 visits ( one week)
postoperative pain and swelling will be measured by:Categorical (4 points). The incidence of postoperative discomfort was recorded and expressed as numbers and percentages Subjectively into 4 points: 1. no pain 2. Mild pain: recognizable but not discomforting pain that required no analgesics. 3. Moderate pain: discomforting but bearable pain(analgesics if used were effective in relieving pain) 4. Severe pain: difficult to bear (analgesics were effective in relieving pain). Patients with severe postoperative pain and/or occurrence of swelling were classified as flare-ups.3 Objectively : percussion test
