Success Rates in Single-Visit Versus Multiple-Visit Root Canal Treatments: A Prospective Study

Root canal treatment (RCT) is a widely performed procedure to address dental pulp infections. However, there is still an argument between the efficacy of single-visit versus multiple-visit RCT, particularly concerning success rates, post-operative pain, and patient satisfaction.

To evaluate and compare the success rates, post-operative complications, and patient satisfaction between single-visit and multiple-visit RCTs in a clinical setting.

A randomized clinical trial was conducted with 100 subjects requiring an RCT. Subjects were divided into two groups: single-visit (n = 50) and multiple-visit (n = 50) treatments. Success rates were evaluated through clinical symptoms and radiographic healing over a 12-month follow-up. Post-operative pain was measured using a "Visual Analog Scale (VAS)" at 24 hours, 48 hours, and 1 week. Patient satisfaction was assessed through a standardized questionnaire.

The success rates were 85% for the single-visit group and 87% for the multiple-visit group, showing no statistically significant difference (P = 0.67). Post-operative pain was slightly higher in the single-visit group at 24 hours (VAS: 4.5 vs. 3.0, P = 0.03), but pain levels were similar by the one-week mark. Patient satisfaction was higher in the single-visit group (92%) compared to the multiple-visit group (85%).

Single-visit and multiple-visit RCTs demonstrated comparable success rates at 12 months. While single-visit treatments resulted in slightly higher post-operative pain initially, they were associated with higher patient satisfaction due to convenience. Both treatment modalities are effective, and the choice should depend on patient-specific factors.
