In endodontics, a failed root canal treatment (RCT) combined with an apical ledge often presents one of the most demanding clinical scenarios. Yet, as demonstrated in this real-world case by Dr. Andrea Balocco, modern rotary file systems can turn complexity into predictability — even completing the entire procedure in a single visit.
Case Overview: Pulp Necrosis, Acute Abscess, and Failed RCT
The patient presented with pulp necrosis in tooth 2.4 and an acute abscess associated with tooth 2.5, alongside a previously failed root canal treatment and a pronounced apical ledge. These conditions typically require careful negotiation, thorough disinfection, and precise shaping while minimizing the risk of further complications such as ledge creation or perforation.
Instead of scheduling multiple appointments, Dr. Balocco achieved full resolution in one efficient visit using KITE GOLD® rotary files by DENCO.
Key Clinical Steps and Techniques
- Access and Initial Negotiation
After gaining access, the existing obturation material from the failed RCT was carefully removed. The apical ledge was identified as the primary obstacle preventing straight-line access to the apical third. - Ledge Bypass with Pre-Bending Technique
A critical moment in this case was bypassing the apical ledge. Dr. Balocco utilized a pre-bending technique with KITE GOLD files to safely negotiate past the ledge without creating new iatrogenic errors. This approach highlights the flexibility and controlled taper of the KITE GOLD system, allowing precise navigation in anatomically challenging canals. - Smooth Canal Shaping to 40/.04
Once the ledge was bypassed, the canals were shaped smoothly and efficiently to a final size of 40/.04. The KITE GOLD files delivered consistent performance with minimal transportation, excellent centering ability, and predictable apical preparation — essential for effective irrigation and obturation in necrotic cases with abscess formation. - Single-Visit Completion
The entire sequence — from ledge management to final shaping — was completed in one appointment. This not only reduced patient discomfort and chair time but also delivered a highly predictable result, as confirmed by the clinical outcome shown in the case.
Why This Case Matters for Modern Endodontics
This clinical demonstration showcases how KITE GOLD rotary files excel in high-difficulty situations:
- Efficient ledge bypass without excessive dentin removal
- Smooth, controlled shaping even in previously treated canals
- Single-visit predictability for necrotic pulp and acute abscess cases
- Reduced risk of procedural errors compared to traditional hand files or less flexible systems
Endodontists and general practitioners facing similar challenges — failed RCT, apical ledges, or acute infections — can draw direct inspiration from this approach.

Conclusion: Predictable Endodontics with KITE GOLD
Dr. Andrea Balocco’s case proves that with the right instrumentation, even the most complicated endodontic scenarios can be managed efficiently and successfully in a single visit. The combination of advanced file design, proper pre-bending technique, and methodical shaping to 40/.04 turned a potentially multi-visit nightmare into a streamlined, predictable success.
For clinicians looking to elevate their root canal outcomes, this KITE GOLD case serves as a powerful real-world example of innovation meeting everyday clinical reality.
