研究概览
简要总结
The purpose of this study is to determine whether maintaining an apical patency causes postoperative pain in posterior teeth with necrotic pulp and apical periodontitis.
详细描述
Apical patency (AP) is a procedure that prevents accumulation of soft and hard tissue debris within the cement canal. However, some RCTs indicate that maintaining an AP causes postoperative pain, whilst some RCTs pointed out there is no difference in terms of pain when AP has been performed. We, therefore, would like to conduct a RCT to increase the sample size of the previously performed RCTs to do an systematic review.

研究组 & 干预措施
Intervention
Endodontic treatment was performed in posterior teeth with necrotic pulp and periapical periodontitis using a reciprocating single-file system (Reciproc). Local anesthesia was provided (2% Novocaine with 1:80,000 epinephrine), isolation with rubber dam and standard access cavity preparation was done.Using 2.5 % sodium hypochlorite, canal negotiation was done & apical patency was achieved with #10 K-files in patency group after determining working length. Coronal flaring with # 2 and #3 Gates-Glidden drills was done. The canals were obturated with gutta-percha and epoxy resin sealer. The treatments were carried out in one-visit.
干预措施: APICAL PATENCY (Procedure)
Control
In the control group, apical patency did not maintained.
结局指标
主要结局
100-mm Visual Analog Scale (VAS).
时间窗: 7 days.
Pain severity was evaluated as no pain (0-4 mm), mild pain (5-44 mm), moderate pain (45-74 mm) and severe pain (75-100 mm).
次要结局
- The number of patients taking an analgesic following the endodontic treatment.(7 days.)
