Single Sitting Root Canal Treatment (RCT) has become the preferred method for addressing infections in damaged or decayed teeth, offering an efficient alternative to tooth extraction. This approach involves completing the entire procedure—cleaning, shaping, and obturation—in a single visit, ensuring a faster and more convenient treatment for patients. Research comparing single-visit and multiple-visit RCTs consistently shows that both methods yield comparable results in terms of effectiveness.

While single-visit RCT achieves all necessary steps in one session, multiple-visit treatments typically involve a temporary medicament, such as calcium hydroxide, placed between the cleaning and shaping phase and the final obturation. The single-sitting approach offers the advantage of minimizing the time and number of appointments needed for successful treatment while still ensuring thorough infection removal and proper sealing for long-term tooth preservation.
