Another MSEO maxillary sinusitis of endodontic origin

A challenging case due to heavy calcification, an inaccessible distobuccal (DB) canal obstructed by the deep crown margin, and maxillary sinus involvement associated with exudate drainage from the periapical lesions of the MB and palatal (P) roots, which had perforated into the sinus floors.

The patient wished to retain the tooth and restore its function rather than proceed with extraction and implant replacement. After discussing the treatment options, the patient elected to proceed with an endodontic approach, including root canal treatment (RCT) and DB root amputation.

Before completing the RCT and proceeding with the DB root amputation, I wanted to confirm that the maxillary sinus had adequately healed and that the associated edema had resolved. Within three weeks following disinfection and intracanal medication of the MB and P canals, the sinus edema had completely resolved, indicating a favorable response to the initial endodontic treatment.

With the sinus condition stabilized, the RCT was completed, and the DB root amputation was subsequently performed as planned.

🦷 MSEO (maxillary sinusitis of endodontic origin)

Endodontic Healing: Tooth #15
This case involved a cracked maxillary molar ( #15) with an endodontic infection that had extended into the left maxillary sinus, causing significant mucosal edema and sinus obstruction.

🔹 Treatment:
Complete root canal instrumentation, irrigation, and disinfection were performed, followed by placement of calcium hydroxide intracanal medicament.

🔹 4-Week Follow-Up:
A 3D CBCT scan demonstrated significant healing of the left maxillary sinus, with resolution of the previously observed mucosal edema and inflammatory changes.

The patient was referred back for placement of a provisional crown to protect and stabilize the tooth during function while allowing additional time for periapical osseous healing.

✨ A great example of how appropriate endodontic treatment can allow both the tooth and surrounding tissues to heal.

🦷 Endodontic Retreatment | Tooth #26

This young patient (25yo) presented with no pain or symptoms, but tooth #26 showed persistent apical pathology associated with a previous root canal treatment (treated in 2015 by a former general dentist).

After discussing treatment options, including apicoectomy versus non-surgical retreatment, the patient elected to remove the existing crown and proceed with retreatment.

🔬 Clinical findings:
Significant staining and contamination were noted throughout the canal system. The existing metal post was carefully removed, allowing access to the canal system for thorough disinfection.

✨ Treatment highlights:
Existing crown removed to evaluate restorability
Non-surgical root canal retreatment
Copious irrigation and intracanal medication
Chairside bleaching to reduce intrinsic discoloration
Permanent fiber post and core
Composite facial veneer for temporary esthetics
New crown planned

The patient tolerated treatment very well. The tooth will be monitored for periapical bone healing at the 6-month follow-up.

A great example of why careful evaluation, thorough disinfection, and appropriate treatment planning are essential in endodontic retreatment cases.

No PARL does not always mean no apical disease

This case involved tooth #6 with a history of trauma decades ago. During a routine cleaning, the amazing referring doctor identified a localized abscess and tissue tag and appropriately referred the patient for endodontic evaluation.

Interestingly, no obvious periapical lesion (PARL) was visible on the periapical radiograph. Yet, the clinical findings strongly suggested an underlying chronic endodontic infection.

The root tip of #6 was positioned outside the main osseous structure, with very thin facial cortical bone. Chronic endodontic infection had resulted in destruction of the thin facial bone, allowing the inflammatory process to extend toward the soft tissue rather than producing the classic, well-defined periapical radiolucency within the surrounding bone. This is an important reminder that the absence of a visible PARL on a 2-D radiograph does not necessarily exclude endodontic disease. The location of the root apex, thickness of the surrounding cortical bone, direction of bone destruction, and limitations of conventional radiography can all influence how an endodontic lesion presents radiographically.

🦷 Diagnosis:
Necrotic pulp with chronic apical abscess

✅ Treatment: One-visit root canal treatment with copious manual irrigation, followed by placement of a permanent bonded packable composite to seal the 1-mm endodontic access under high magnification.

✨ The patient tolerated treatment well, with no pain or discomfort during or following the procedure.

📅 Follow-up:
3-month recall to monitor healing.

🦷 Endodontic Treatment | Tooth #19 | 81 yo female
A case of tooth #19 presenting with a buccal abscess and chronic apical infection was treated with two-visit non-surgical root canal treatment . 6-canal system: 2 mesials 1 lateral 3 distals
✨ Treatment highlights:
GentleWave® irrigation protocol
Intracanal medication between visits
Buccal abscess resolved by the second day
At the 2-week follow-up: healthy gingival tissues with no recurrent swelling or drainage
Permanent core buildup and crown repair completed at the time of obturation
The tooth is now scheduled for 3 month follow-up to monitor periapical bone healing.
A great example of how thorough disinfection can support predictable endodontic healing. 🦷✨

Small, simple, and beautiful. 🦷✨
A premolar with a single canal and delicate lateral anatomy — a great reminder that even the smallest details matter in endodontics. Conservative access. Precise shaping. Copious manual irrigation. Three-dimensional obturation. 💫

Grossly decayed tooth—radiographically, it appeared non-restorable. After thorough caries removal, endodontic treatment, and a new post-and-core restoration, the tooth is now ready for a full-coverage crown.

Saving natural teeth is always the first choice whenever possible. 🦷✨

I had the privilege of speaking with the AEGD residents at VA Long Beach today, just four weeks before they complete their program. We had a great discussion on practice management, associationship opportunities, and some of the key things to look for as they begin the next chapter of their careers.

Of course, I couldn’t let them leave without talking about one of my favorite subjects—Endodontics!

Congratulations to these outstanding doctors. They have already demonstrated excellence by graduating near the top of their classes from UCSF, UCLA, Michigan, and Western University College of Dental Medicine. Now, they are finishing the VA Long Beach AEGD program with the confidence, clinical skills, and determination to become highly competent dentists serving their communities.

It’s inspiring to see the future of dentistry in such capable hands. Wishing each of them continued success as they embark on their professional journeys. 👏🦷 DentalEducation FutureOfDentistry
