Aim to compare incidence of post-operative pain and apical healing after single-visit versus two-visit root canal treatment of teeth with necrotic pulp and apical periodontitis.
Methodology: All teeth of the one and two-visit group were asymptomatic (92) and symptomatic (18) with a diagnosis of pulp necrosis (RCT cases) determined by hot and cold sensitivity tests and radiographically all teeth showed a small and irregular radiolucency at the tooth apex. Working length was established with EAL and confirmed radiographically. Reciprocating files (VDW, Munich Germany) were used to complete root canal preparation. EDTA served as a lubricant.
- Procedure: One visit RCT
- Root canal treatment in one vist
- Procedure: Post operative pain in two-visits RCT
- Root canal treatment in Two visits
Arms, Groups and Cohorts
- Experimental: Post operative Pain in one visit RCT
- One visit RCT Ibuprofen for Post operative pain. Take 400 mg every 6 hours, a week after.
- Experimental: Post operative pain in two-visits RCT
- Two visits RCT Ibuprofen for Post operative pain. Take 400 mg every 6-8 hours, a week after.
Clinical Trial Outcome Measures
- Post-operative pain in one visit
- Time Frame: one week
- Pain intensity measure with general pain scale Each patient will recall a week to evaluate post operative pain
Participating in This Clinical Trial
1. The aims and requirements of the study were freely accepted;
2. Treatment was limited to patients in good health;
3. All teeth had nonvital pulps and apical periodontitis, with or without a sinus tract;
4. A negative response to hot and cold pulp sensitivity tests;
5. Presence of sufficient coronal tooth structure for rubber dam isolation;
6. No prior endodontic treatment on the involved tooth
7. No analgesics or antibiotics were used five days before the clinical procedures began.
1. Patients who did not meet inclusion requirements;
2. Patients who did not provide authorization for participation;
3. Patients who were younger than 16 years old;
4. Patients who were pregnant;
5. Patients who were diabetic;
6. Patients with a positive history of antibiotic use within the past month;
7. Patients whose tooth had been previously accessed or endodontically treated;
8. Teeth with root resorption,
9. Immature/open apex, or a root canal in which patency of the apical foramen could not be established were all excluded from the study. Teeth with periodontal pockets deeper than 4 mm also were excluded of the study.
