This study evaluates the postoperative pain and long-term clinical and radiographic success of single-visit primary root canal treatment in asymptomatic teeth with periapical lesions.
Patients aged 18-65 years.
Teeth that have not previously undergone root canal retreatment or surgical intervention.
Patients who are able to read and sign the informed consent form.
Patients who are physically and mentally able to tolerate the planned dental treatment.
Pregnant or lactating women.
Patients with chronic periodontal disease and/or a periodontal probing depth >4 mm.
Symptomatic patients.
Patients who are unable to comply with the scheduled follow-up periods.
Parallel
One-Fill
Other interventionRoot canal obturation using One-Fill bioceramic sealer with a single-cone technique. The prepared root canal is filled with a fitted gutta-percha cone coated with One-Fill sealer according to the manufacturer's instructions.
TotalFill
Other interventionRoot canal obturation using TotalFill BC Sealer with a single-cone technique. The prepared root canal is filled with a fitted gutta-percha cone coated with TotalFill BC Sealer according to the manufacturer's instructions.
AH Plus + Single Cone
Other interventionRoot canal obturation using AH Plus epoxy resin-based sealer with a single-cone technique. A fitted gutta-percha cone is coated with AH Plus sealer and placed to the working length according to the study protocol.
AH Plus + Continuous Wave
Other interventionRoot canal obturation using AH Plus epoxy resin-based sealer with the continuous wave of condensation technique. The master gutta-percha cone is fitted to the working length, followed by down-pack and backfill procedures using heated gutta-percha according to the study protocol.
Postoperative Pain
Postoperative pain following single-session primary root canal treatment, assessed using a 10-point visual analog scale (VAS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. higher scores indicate greater pain intensity.
Clinical Success and Radiographic Radiographic Changes in Periapical Lesion Size Following Root Canal Treatment
Radiographic assessment of periapical lesion size following single-session primary root canal treatment. Periapical lesion size will be measured on digital periapical radiographs using image analysis software. A coin of known diameter will be used as a radiographic calibration reference to standardize measurements. The maximum diameter of the periapical radiolucency will be measured in millimeters (mm) at each follow-up examination (1, 3, 6, and 12 months). Changes in lesion size will be calculated by comparing measurements obtained at baseline and subsequent follow-up examinations.
