简要总结
the aim of the study is to evaluate the effect of cryotherapy on postoperative pain in molar teeth with irreversible pulpitis and apical periodontitis
详细描述
the purpose of the study was to evaluate the effect of 2.5c cold saline irrigation as a final irrigant on postoperative pain after single visit root canal treatment of teeth with vital pulp and apical periodontitis .thirty patients will be included in the study .the teeth will be divided into 2 groups (i.e the control group and the cryotherapy group ) in the cryotherapy group ,final irrigation with 2.5c cold saline solution for 5 mins will be performed following completion of biomechanical preparation whereas in control group same solution stored at room temperature will be used . treatment will be done in a single visit then participants will be asked to rate the intensity of postoperative pain using numerical rating scale at 6,12,24,48 hrs

结局指标
主要结局
postoperative pain assessed by NRS
时间窗: up to 48 hrs postoperative pain
Primary outcome (post-operative pain) will be collected by the operator through (NRS) which is an 11 point scale consisting of numbers from 0 through 10 0: reading represents "no pain" 1- 3: readings represent "mild pain" 4- 6: readings represent "moderate pain" 7- 10: readings represent "severe pain"
次要结局
- amount of analgesics assessed by counting(up to 48 hrs postoperatively)
