Endo Addict

An 11-year-old female patient presented to my clinic complaining of:

🔸 Severe pain in the lower right posterior region
🔸 Grade II mobility of the mandibular first molar
🔸 Mild facial swelling

On taking the history, the patient's parent reported that the tooth had received a composite restoration approximately 9 months earlier, but no endodontic treatment had been performed.

After thorough clinical and radiographic examination, the diagnosis was established as:

✅ Pulpal Diagnosis: Necrotic Pulp
✅ Periapical Diagnosis: Symptomatic Apical Periodontitis with symptomatic apical involvement

🩺 Treatment Plan
First Visit (Emergency Appointment)

✔️ Access cavity preparation
✔️ Complete chemo-mechanical preparation with thorough cleaning and shaping of the canals
✔️ Irrigation protocol performed meticulously
✔️ The canals were sealed at the end of the visit without placing an intracanal medicament, aiming to control the infection through effective debridement and a well-sealed environment.

Second Visit (1 Week Later)

The patient returned completely comfortable with resolution of pain and facial swelling.

Treatment included:

✔️ Final irrigation protocol
✔️ Three-dimensional obturation of the root canal system
✔️ Coronal sealing of the access cavity

The tooth was then referred to the prosthodontic team for definitive coronal restoration, ensuring long-term protection against coronal leakage and fracture.

# # Saving a Strategic Premolar: When Every Millimeter Matters

A 23-year-old female patient was referred by her prosthodontist for nonsurgical root canal retreatment of a her first premolar. The tooth was asymptomatic, but radiographic examination revealed a short previous root canal filling associated with localized asymptomatic apical periodontitis, indicating persistent infection despite the absence of clinical symptoms.

The case presented a unique challenge. Although the remaining coronal tooth structure was in a compromised but manageable condition, the tooth held significant esthetic and functional value for the patient. With a wide smile line and a strong desire to preserve her natural dentition, maintaining this premolar was especially important because the adjacent first molar had already been extracted. Losing the premolar would have further complicated her restorative options and negatively impacted long-term function.

A thorough discussion was held with the referring prosthodontist regarding the restorability and strategic value of the tooth. Following clinical and radiographic assessment, the tooth was deemed restorable with a favorable restorative prognosis. The prosthodontist's request was clear: provide the highest possible quality of endodontic treatment to maximize the long-term survival and success of the tooth within the overall treatment plan.

Despite the challenging root canal anatomy, a decision was made to complete the retreatment in a single visit. This approach was chosen to minimize the risk of coronal leakage and bacterial recontamination associated with temporary restorations between appointments, particularly in a tooth where preservation of the remaining structure was critical.

The previous root canal filling was carefully removed, the complex canal system was thoroughly cleaned and disinfected, and the canals were obturated to their full working length. The treatment was completed successfully in one session, providing an optimal biological foundation for definitive restoration.

This case highlights the importance of interdisciplinary treatment planning, strategic tooth preservation, and meticulous endodontic retreatment. Even in the presence of apical pathology and challenging anatomy, a well-executed nonsurgical retreatment can offer a predictable opportunity to retain a valuable natural tooth and support long-term restorative success.

A 28-year-old patient walked into the clinic… not because of pain — but because of fear.

He had already been scheduled for apical surgery.
For him, it felt like the only option left.

But something didn’t sit right.

So he walked away… searching for another opinion — hoping, somehow, there was still a way to save his tooth without going surgical.

What he came with wasn’t a simple case.

Tooth #24 had already been through a failed endodontic attempt.
Two separated instruments were left behind — one buried deep in the apical third, the other trapped in the middle of the canal.

And as if that wasn’t enough…
An attempt to bypass the file had ended with a root perforation.

A case many would consider… already lost.

Yet despite all this, the patient’s only request was clear:

“Just… don’t let it end in surgery.”

🧠 The Challenge
- Two separated instruments in the same canal
- Apical lesion with cortical bone involvement
- Root perforation
- Open tooth contaminated with debris
- Patient reluctant for surgical intervention

🎯 The Plan

Instead of jumping to surgery, we chose a conservative approach:

- Retrieve what can be retrieved
- Bypass what cannot
- Seal the perforation
- Give biology a chance to heal

⚙️ The Ex*****on

Under magnification:

✔️ The coronal separated instrument was successfully retrieved using ultrasonics
✔️ The apical fragment was carefully bypassed
✔️ Full chemo-mechanical preparation completed
✔️ Perforation sealed using bioceramic material
✔️ Obturation done with warm vertical compaction + bioceramic sealer
✔️ Final restoration with fiber post & composite - case referred to make cuspal coverage restoration

⏳ The Outcome

No surgery. No extraction. No complications.

At 9-month follow-up:
✅ Complete healing
✅ Patient symptom-free
✅ Tooth preserved

(Healing confirmed radiographically and clinically)

💡 The Message

Sometimes… it’s not about what’s broken.
It’s about how far you’re willing to go to save it.

👉 Even in complex cases with separated files and perforations,
non-surgical retreatment can still win — if done right.
