Comparing One-Visit vs Two-Visit Root Canal Treatments for Infected Teeth in General Dental Practice

What this Trial Is About

Researchers are comparing one-visit versus two-visit root canal treatments for infected necrotic teeth in general dental practice. The study aims to evaluate the outcomes one and four years after treatment, focusing on periapical health, root filling quality, and complication rates. A pilot study will first identify and address any protocol issues before the main multicenter trial across several clinics in Sweden begins. Patients will be randomly assigned to receive either a root canal treatment completed in one visit or in two visits spaced at least one week apart. Both treatment methods follow standard clinical practices without rigid protocols. After treatment, patients will have a phone call 5-7 days later, a control visit at one month, and clinical evaluations at one and four years including intra-oral radiographs reviewed by independent observers. During the study, participants will undergo regular assessments of post-operative pain, medication use, tooth survival, and any complications. Follow-up includes clinical exams and radiographic checks to determine treatment success based on clinical and radiographic normalcy. The study plans to recruit about 1000 patients to ensure statistically meaningful results, with monitoring continuing up to four years after treatment completion.
