Abstract:
Objective:To study clinical efficacy of one-visit versus two-visit root canal therapy for pulpitis, apical periodontitis and taintless teeth with nickel-titanium rotary instruments and ultrasonic irrigation unit. Methods: A total of 309 patients with 338 teeth were selected. The teeth were classified into pulpitis group, apical periodontitis group and taintless teeth group. Patients were randomly assigned to either the one-visit or two-visit root canal therapy, the treatment effects were evaluated with clinical trial and radiography after 3 days, 1 week, 1 month and 3 months. Results: The short-term outcome was changes in apical bone density by using the periapical index (PAI), long-term outcome exhibited equally improvement in clinical curative effect in both groups. Although one-visit root treatment could cause more intensive postoperative pain than that of two-visit endodontic treatment during 1-3 days, the indisposition could be eliminated by using medicine. Conclusion: By using of the nickel-titanium rotary instruments and canal ultrasonic irrigation unit, the cure rate of root canal therapy of one-visit and two-visit endodontic treatment has been improved, with no significant difference between two groups, so that one-visit root treatment can be used in clinic.
