Root-End Resection Surgery in Beaverton, OR
Root-end Resection Surgery is a specialized dental service provided by the board-certified specialists Dr. Merat Ostovar and Dr. Jovan Gvozden at Aloha Dental Specialty Center in Beaverton, OR. When conventional retreatment cannot resolve a persistent root canal infection, apicoectomy offers a microsurgical solution. Our specialists remove the infected root tip, place a biocompatible retrograde seal, and preserve your natural tooth with predictable, long-lasting results.
Microsurgical Apicoectomy: Saving Teeth When Retreatment Is Not an Option
Root-end resection, commonly known as apicoectomy, is a microsurgical endodontic procedure performed when non-surgical retreatment cannot adequately address persistent periapical infection. The procedure involves accessing the root apex through a small window in the buccal bone, resecting the apical 3 mm of the root tip — the region containing the most complex and unpredictable canal anatomy including ramifications, deltas, and lateral canals — and placing a retrograde filling material to seal the canal from the apex. At Aloha Dental Specialty Center, our endodontic specialists perform apicoectomy using modern microsurgical protocols that have improved success rates from the 60% range reported with traditional techniques to 88–97% with contemporary microsurgical approaches.
The indications for apicoectomy are specific and clinically driven. We recommend this procedure when non-surgical retreatment has already been attempted and failed, when retreatment is not feasible due to a well-fitting post and core that cannot be safely removed, when the canal is obstructed by a separated instrument that cannot be bypassed, when there is an apical root fracture confined to the resected segment, or when anatomical complexity at the apex (such as severe apical delta formation or lateral canal communication) prevents adequate disinfection from a coronal approach. In each of these scenarios, the surgical approach allows us to address the pathology directly at its source.
Modern microsurgical apicoectomy bears little resemblance to the traditional apicoectomy of decades past. We use the dental operating microscope at 8x to 25x magnification throughout the entire procedure, microsurgical instruments specifically designed for root-end preparation, and biocompatible retrograde filling materials such as mineral trioxide aggregate (MTA) or Biodentine that create a hermetic seal at the resected apex. The osteotomy is minimal — typically 4 to 5 mm in diameter — and the incision is designed for primary closure with microsurgical sutures. This contemporary approach results in faster healing, less post-operative discomfort, and significantly higher long-term success rates compared to older techniques.

Recovery After Root-End Resection Surgery
First 24–72 Hours
Swelling is expected and typically peaks at 48 to 72 hours after surgery. Apply ice packs to the affected side (20 minutes on, 20 minutes off) for the first 24 hours to minimize swelling. Take prescribed anti-inflammatory and pain medications on schedule — do not wait for pain to develop before taking them. Avoid blowing your nose if the surgery was near the maxillary sinus. Eat soft, cool foods and avoid the surgical area when chewing. Minor bruising of the facial skin may occur and resolves within five to seven days.
Days 4–14
Swelling begins to subside and discomfort decreases substantially. Sutures are typically removed at seven to ten days. You may gradually return to a normal diet as comfort allows, though continue to avoid hard or crunchy foods on the surgical side for two weeks. Brush and floss normally away from the surgical site, and gently rinse with the prescribed antimicrobial mouthwash. Most patients return to work within two to three days of surgery, though strenuous physical activity should be avoided for one week.
Months 1–12
Bone regeneration at the surgical site is a gradual process that we monitor with periodic radiographs. Initial signs of healing are visible at one month, with progressive improvement at three, six, and twelve months. The cortical bone window created during surgery fills in with new bone over this period. We schedule follow-up imaging at three months and one year to confirm successful healing. Complete radiographic resolution of the periapical pathology is expected within six to twelve months in the majority of cases.
Microsurgical Precision: How Modern Apicoectomy Achieves Superior Outcomes
The dramatic improvement in apicoectomy success rates over the past two decades is attributable to three technological advances: the dental operating microscope, ultrasonic root-end preparation tips, and bioactive retrograde filling materials. The microscope provides illumination and magnification that allow the surgeon to inspect the resected root surface for isthmuses (thin connections between canals), microfractures, and lateral canal openings that would be invisible without magnification. After resecting the apical 3 mm at a near-perpendicular angle — which eliminates the bulk of apical ramifications and reduces the exposed dentinal tubule surface area by 98% compared to the beveled resections used in traditional technique — we prepare a 3 mm deep retrograde cavity using ultrasonic tips that follow the canal anatomy precisely. This cavity is then filled with mineral trioxide aggregate (MTA) or bioactive ceramic cement, materials that are hydrophilic, set in the presence of moisture, create a biological seal against the dentin, promote cementogenesis on the root surface, and demonstrate excellent biocompatibility in periapical tissues. Studies comparing microsurgical apicoectomy with traditional techniques consistently show weighted success rates of 91–94% at one year and 88–91% at four to six years for microsurgical cases, compared with 44–68% for traditional approaches. These outcomes reflect the precision that microsurgery brings to every aspect of the procedure.
Why Choose a Specialist for Root-End Resection Surgery?
Apicoectomy is a microsurgical procedure that demands expertise in both endodontic diagnosis and surgical technique. At Aloha Dental Specialty Center, our specialists trained in accredited endodontic residency programs where they performed hundreds of apicoectomies under the supervision of fellowship-trained faculty. This training included mastery of microsurgical flap design, atraumatic tissue management, precision osteotomy, root-end preparation with ultrasonic instruments, and retrograde obturation with bioactive materials. Beyond residency, our specialists have continued to refine their surgical skills through years of clinical practice and continuing education focused on the latest microsurgical advances. We perform apicoectomies on all tooth types — from anterior teeth with straightforward access to posterior molars where proximity to the maxillary sinus, inferior alveolar nerve, or mental foramen requires meticulous pre-surgical planning with CBCT. When your general dentist or a previous endodontist determines that non-surgical retreatment cannot resolve your infection, you can trust that our team has the surgical skill, the technology, and the clinical judgment to give your natural tooth the best chance of long-term survival.

A Note from Your Dental Team
In my experience, the patients who get the best results from root-end resection surgery are those who come in with realistic expectations and follow their post-treatment instructions carefully. I’d rather spend extra time explaining what to expect than have a patient be surprised later.
“Every patient I see has a different story, a different set of concerns, and a different definition of what ‘success’ looks like. That’s why I don’t believe in one-size-fits-all treatment plans. When you come in for a consultation, I’ll listen first, examine second, and recommend third.
I also won’t recommend a procedure you don’t need. If your tooth can be saved with a filling instead of a crown, I’ll tell you that. If watchful waiting is appropriate, I’ll explain why. My job isn’t to sell treatment — it’s to give you my honest clinical judgment so you can make an informed decision.
If you have questions about whether this treatment is right for you, or if you’ve been told you need this procedure by another dentist and want a second opinion, call us at (503) 822-0096. We’re happy to take the time to explain everything — no rush, no pressure.”

I know many patients feel anxious about dental procedures — you’re not alone in that. What I hear most often after treatment is: “That was so much easier than I expected.” We’re here to make this as comfortable as possible for you.
Are You a Candidate for Root-end Resection Surgery?
Most patients in good general health are candidates for root-end resection surgery. However, certain factors may affect your eligibility or require modifications to the treatment plan:
- Medical conditions: Uncontrolled diabetes, autoimmune disorders, or blood-thinning medications may require coordination with your physician before treatment.
- Bone quality: For root-end resection surgery involving the jawbone, adequate bone density is essential. A CBCT 3D scan during your consultation determines this precisely.
- Smoking: Tobacco use significantly impairs healing. We strongly recommend quitting 2-4 weeks before and after any surgical procedure.
- Age: There is generally no upper age limit. What matters is your overall health, not your age. We have successfully treated patients in their 80s and 90s.
The only way to know for certain is a consultation with our board-certified specialists. Call (503) 822-0096 to schedule your evaluation — we’ll tell you honestly whether this is the right treatment for your situation.
Typical Healing Timeline:
Days 1-3: Initial healing, mild swelling managed with ice and medication. Days 4-7: Swelling subsides, gradual return to normal diet. Weeks 2-4: Soft tissue heals completely. Months 2-6: Bone remodeling and full integration (for surgical procedures). Individual recovery varies — we provide detailed post-op instructions specific to your procedure.

Frequently Asked Questions About Root-End Resection
What is a root-end resection (apicoectomy)?
A root-end resection, or apicoectomy, is a microsurgical procedure in which the endodontic specialist accesses the tip (apex) of a tooth root through a small opening in the bone, removes the last 3 millimeters of the root, and places a biocompatible filling material to seal the canal from the bottom. The procedure targets persistent infection that non-surgical root canal retreatment cannot resolve, preserving the natural tooth and avoiding extraction.
When is apicoectomy recommended instead of retreatment?
Apicoectomy is recommended when non-surgical retreatment is not feasible or has already failed. Specific indications include: a post and core that cannot be safely removed without fracturing the root, a separated instrument in the canal that cannot be bypassed, persistent infection after a technically adequate retreatment, complex apical anatomy that cannot be cleaned from a coronal approach, suspected apical root fracture, or calcification that prevents canal negotiation. We always consider retreatment first and recommend surgery only when it offers the best prognosis.
What is the success rate of microsurgical apicoectomy?
Contemporary microsurgical apicoectomy performed with an operating microscope, ultrasonic root-end preparation, and bioactive retrograde filling materials achieves success rates of 88–97% in published peer-reviewed literature. These rates are significantly higher than the 60% success rates associated with traditional apicoectomy techniques. The specific prognosis for your tooth depends on factors including the tooth type, the size of the periapical lesion, the presence of a root crack, and the quality of the existing root canal obturation.
Is apicoectomy painful?
The procedure is performed under local anesthesia, and most patients report no pain during surgery. We offer sedation options for patients who experience anxiety. Post-operatively, swelling is the most common complaint, peaking at 48–72 hours and resolving within one to two weeks. Pain is typically mild to moderate and well-managed with prescribed anti-inflammatory medications and over-the-counter analgesics. Most patients describe the overall experience as far more comfortable than they anticipated.
How long does the surgery take?
Apicoectomy typically takes 45 to 90 minutes depending on the tooth involved, the number of roots requiring treatment, and the anatomical complexity (proximity to nerves, sinus, or adjacent roots). Anterior teeth are generally faster due to straightforward access, while posterior molars may require more time due to limited visibility and proximity to critical structures. We allow ample appointment time so the procedure is never rushed.
What material is used for the retrograde filling?
We primarily use mineral trioxide aggregate (MTA) or bioactive ceramic cements such as Biodentine for retrograde fillings. These materials are hydrophilic (they set in the presence of moisture), create a tight biological seal against dentin, promote cementogenesis (the formation of new cementum on the resected root surface), and demonstrate excellent biocompatibility with periapical tissues. MTA has been the gold standard retrograde filling material for over two decades and has extensive research supporting its long-term success.
How much swelling should I expect?
Swelling after apicoectomy varies by individual and by tooth location. Upper anterior teeth typically produce mild to moderate swelling of the lip or area below the nose. Upper posterior teeth may cause swelling of the cheek. Lower teeth may cause swelling along the jawline. Swelling peaks at 48–72 hours and gradually resolves over seven to fourteen days. Applying ice packs in the first 24 hours and keeping your head improved when sleeping help minimize swelling. We prescribe anti-inflammatory medications to further control the inflammatory response.
Will I need time off work?
Most patients take one to two days off work following apicoectomy. The day of surgery is typically spent resting at home with ice application and medication. By the second or third day, most patients feel well enough to return to desk work or light duties. Physical labor and exercise should be avoided for five to seven days. If your job involves heavy lifting, bending, or strenuous activity, plan for a full week of modified duty.
Can apicoectomy be performed on any tooth?
Apicoectomy can be performed on most teeth, though the surgical approach varies by tooth location. Anterior teeth and premolars have the most straightforward access. Upper molars require consideration of the maxillary sinus, and the palatal root may be difficult to access surgically. Lower molars require careful management of the inferior alveolar nerve and mental foramen. Lower premolars and second molars can be challenging due to thick buccal cortical bone. We use CBCT imaging to evaluate surgical access, proximity to vital structures, and bone thickness before recommending surgery for any specific tooth.
What happens if apicoectomy fails?
If an apicoectomy does not achieve resolution of the periapical pathology, the options include a second surgical procedure (re-surgery), intentional replantation (extracting the tooth, treating it outside the mouth, and replanting it), or extraction with replacement by an implant or bridge. The likelihood of failure is low with microsurgical techniques, but if the cause of failure is a vertical root fracture or an undetectable crack, extraction is typically necessary. We discuss all contingency plans during the pre-surgical consultation.
How does apicoectomy compare to extraction and implant placement?
When apicoectomy has a favorable prognosis, it preserves the natural tooth, maintaining proprioception, periodontal ligament function, and alveolar bone volume. The procedure is typically completed in one surgical visit with a shorter overall treatment timeline than extraction, grafting, implant placement, and restoration — which can span six to twelve months. However, if the tooth has a poor prognosis due to fracture, severe bone loss, or insufficient remaining structure, an implant may offer better long-term predictability. We present both options with honest prognosis estimates so you can make an informed decision.
Why is only 3 mm of the root tip removed?
Research by Kim and colleagues demonstrated that the apical 3 mm of the root contains 93% of apical ramifications and 98% of lateral canal branches. By resecting this segment, the vast majority of complex anatomy that harbors bacteria is eliminated. Removing more than 3 mm would reduce the crown-to-root ratio and compromise the tooth’s long-term stability without significant additional benefit. The perpendicular or near-perpendicular resection angle used in microsurgical technique further minimizes the exposed dentinal tubule surface area, reducing the risk of leakage from the resected surface.
Do I need a CBCT scan before apicoectomy?
Yes, CBCT imaging is essential for pre-surgical planning. It reveals the three-dimensional relationship of the root apex to critical anatomical structures (maxillary sinus, inferior alveolar nerve, mental foramen, adjacent roots), the thickness of the buccal cortical bone, the size and extent of the periapical lesion, and whether the pathology involves one or multiple roots. This information determines the surgical approach, incision design, osteotomy location, and the feasibility of the procedure. We obtain CBCT imaging in our office during your consultation appointment.
Will my insurance cover apicoectomy?
Most dental insurance plans provide coverage for apicoectomy, as it is classified as a surgical endodontic procedure. Coverage levels vary by plan, and some plans require documentation of a prior root canal or retreatment before approving surgical intervention. Our team submits pre-authorization with CBCT images, clinical photographs, and a detailed narrative to maximize your coverage. We provide a clear cost estimate showing your expected out-of-pocket responsibility before scheduling the surgery.
What is the difference between traditional and microsurgical apicoectomy?
Traditional apicoectomy used a large bur for root-end preparation, amalgam for the retrograde filling, and was performed without magnification, resulting in larger osteotomies, beveled root resections, and success rates around 60%. Microsurgical apicoectomy uses an operating microscope for the entire procedure, ultrasonic tips for precise root-end preparation, bioactive materials (MTA or Biodentine) for the retrograde filling, and microsurgical instruments for atraumatic tissue management. The osteotomy is smaller (4–5 mm vs. 8–10 mm), the resection angle is perpendicular, and published success rates are 88–97%. At Aloha Dental Specialty Center, we exclusively perform the microsurgical technique.
Schedule Your Root-End Resection Consultation
If a previous root canal has failed and retreatment is not an option, microsurgical apicoectomy may be the solution. Our endodontic specialists will evaluate your tooth with CBCT imaging, discuss your options, and determine whether root-end resection can save your natural tooth.
