Successful Endodontic Retreatment with Denco D-FILES and PA FILES – A Case Study by Dr. Armin Okić
Introduction
Endodontic retreatment requires precision, high-quality instruments, and effective irrigation protocols to ensure optimal results. In this case study, Dr. Armin Okić from Bosnia and Herzegovina shares a successful endodontic retreatment performed using Denco D-FILES (rotary files) and Denco PA FILES (pathfinding files), along with Denco’s endo activator and gutta-percha for obturation.
Patient Case Overview
A patient presented with a previously unsuccessful endodontic treatment on tooth 15, requiring retreatment in preparation for prosthetic therapy. After a thorough clinical and radiographic examination (Image 1), Dr. Okié decided to retreat the tooth using Denco rotary D-FILES for efficient shaping and cleaning.
First Visit: Cleaning and Shaping with Denco D-FILES
The retreatment process began with the removal of the old filling material and thorough irrigation using 2.5% NaOCl and 17% EDTA. To enhance the irrigation efficacy, Denco’s endo activator was used for improved penetration and debris removal.
After proper canal preparation, calcium hydroxide (CaOH2) was placed as an intracanal medicament for ten days (Image 2) to disinfect and prepare the canal for final obturation.
Second Visit: Glide Path and Obturation with Denco PA FILES and Gutta-Percha
In the second appointment, odontometry was performed to confirm working length. A glide path was established using Denco PA FILES (013, 016, and 019), ensuring smooth and safe progression of subsequent instruments. Additional copious irrigation with NaOCl and activation further ensured a debris-free canal.
Finally, the root canal was obturated using:
- A Denco master gutta-percha cone (20/04)
- A combination of the monocone and cold lateral condensation technique (Image 3)
The patient was then referred to a prosthetic specialist for further restoration.
Conclusion
This case demonstrates the effectiveness of Denco endodontic instruments, particularly the Denco D-FILES for retreatment and Denco PA FILES for glide path creation. The use of Denco’s endo activator and gutta-percha further contributed to a predictable and successful outcome.
For dentists seeking reliable, high-performance endodontic files, Denco D-FILES and PA FILES provide excellent results in both primary treatments and retreatments.
