Apicoectomy in Da Nang – Root End Surgery

Apicoectomy, also known as root end surgery, root end resection, or periradicular surgery, is a specialized microsurgical procedure that removes the very tip (apex) of a tooth root along with surrounding infected tissue when conventional root canal treatment or retreatment has failed to eliminate a persistent infection. At Picasso Dental Clinic inside Vinmec Da Nang International Hospital, our dentists perform apicoectomies using modern surgical techniques, biocompatible root-end filling materials, and CBCT 3D imaging for precise surgical planning, offering international patients a last-resort solution to save teeth that might otherwise require extraction.

Apicoectomy represents the final line of defense in endodontic therapy. When a tooth has undergone root canal treatment but continues to harbor infection at the root tip, the problem often lies in the complex apical anatomy, including lateral canals, deltas, and isthmuses that are impossible to clean through conventional canal instrumentation. By surgically accessing the root tip from outside the tooth, the infected tissue and the problematic apical anatomy can be removed and the root end sealed definitively. This approach has a high success rate and can extend the functional life of a treated tooth for many years or even decades.

What Is an Apicoectomy?

An apicoectomy is a minor surgical procedure performed through the gum tissue and bone to access the tip of a tooth root. The procedure involves:

1. Making a small incision in the gum tissue near the affected tooth
2. Reflecting a tissue flap to expose the underlying bone
3. Creating a small window in the bone to access the root tip
4. Removing approximately 3 millimeters of the root tip (apex)
5. Cleaning out the periapical lesion (infected tissue, cyst, or granuloma)
6. Preparing a small cavity in the cut root surface
7. Placing a biocompatible root-end filling (typically MTA or Biodentine) to seal the root
8. Repositioning the tissue flap and placing sutures

The entire procedure typically takes 30 to 60 minutes per tooth and is performed under local anesthesia.

Who Needs an Apicoectomy?

Patients with Failed Root Canal Treatment

The most common indication for apicoectomy is a persistent periapical lesion (infection at the root tip) that has not resolved despite adequate root canal treatment or retreatment.

Patients Where Retreatment Is Not Feasible

In certain situations, conventional retreatment through the crown of the tooth is not possible or practical:

• Posts or cores that cannot be safely removed without risking root fracture
• Existing high-quality restorations such as porcelain crowns or bridges that would need to be destroyed for retreatment access
• Calcified or blocked canals that cannot be negotiated from the coronal approach
• Separated instruments lodged in the canal that prevent thorough cleaning

Patients with Specific Pathology

• Periapical cyst: A fluid-filled sac at the root tip that may not resolve with root canal treatment alone
• Periapical granuloma: Chronic inflammatory tissue at the root tip
• Root perforation: A perforation near the root tip that can be repaired surgically
• Horizontal root fracture: When the apical fragment can be removed while preserving the coronal portion

Patients Seeking to Avoid Extraction

When the only alternative to apicoectomy is tooth extraction and replacement with an implant or bridge, many patients prefer to attempt apicoectomy as a less invasive and less costly option.

Benefits of Apicoectomy

Saves Your Natural Tooth

The primary benefit of apicoectomy is preserving a tooth that would otherwise be lost. A natural tooth provides superior proprioception (the ability to sense biting forces) compared to any artificial replacement.

High Success Rate

Modern apicoectomy using microsurgical techniques and biocompatible root-end filling materials achieves success rates of 85 to 97 percent, comparable to or better than root canal retreatment.

Preserves Existing Dental Work

Apicoectomy accesses the root from outside the tooth, meaning existing crowns, posts, and bridges do not need to be removed. This saves both time and money.

Definitive Treatment

By physically removing the infected root tip and surrounding pathology and sealing the root end, apicoectomy eliminates the source of infection in a definitive manner.

Cost-Effective Alternative to Extraction and Implant

The cost of apicoectomy (USD $87 to $350) is typically less than extraction followed by implant placement, especially when the existing crown can be preserved.

Biopsy Capability

The tissue removed during apicoectomy can be sent for histopathological examination, providing a definitive diagnosis that may be important for certain pathological conditions.

The Apicoectomy Procedure at Picasso Vinmec

Step 1: Pre-Operative Imaging

CBCT 3D imaging is obtained to precisely evaluate:

• The size and extent of the periapical lesion
• Root tip morphology and the number of roots involved
• Proximity to the inferior alveolar nerve, mental foramen, or maxillary sinus
• Root length remaining after apex resection
• Adjacent tooth root positions

Step 2: Anesthesia

Thorough local anesthesia is administered. For apicoectomy, we use a combination of infiltration and block anesthesia to achieve profound numbness of the surgical area.

Step 3: Incision and Flap Design

A carefully designed incision is made in the gum tissue, taking into account esthetic considerations (especially for front teeth), blood supply, and access requirements. The tissue flap is gently reflected to expose the bone overlying the root tip.

Step 4: Osteotomy

A small window is created in the bone using a surgical handpiece with saline irrigation. In many cases where a periapical lesion has already eroded the bone, the root tip may be partially visible without extensive bone removal.

Step 5: Root End Resection

The last 3 millimeters of the root tip are resected (cut) at a slight bevel. This distance removes the most complex apical anatomy, including the majority of lateral canals and the apical delta where bacteria harbor.

Step 6: Curettage of Periapical Lesion

All pathological tissue (cyst lining, granuloma, infected granulation tissue) is carefully curetted from the bony cavity. The tissue is collected for histopathological analysis.

Step 7: Root End Preparation

Using ultrasonic tips specifically designed for endodontic surgery, a small cavity is prepared in the center of the cut root surface, following the canal anatomy, to a depth of approximately 3 millimeters.

Step 8: Root End Filling

The prepared cavity is filled with a biocompatible material, typically MTA (Mineral Trioxide Aggregate) or Biodentine, which seals the root end and promotes bone healing around the tooth.

Step 9: Closure

The tissue flap is repositioned and sutured into place. The sutures are typically removed or dissolve within 5 to 7 days.

International Cost Comparison

Aftercare Following Apicoectomy

First 48 Hours

• Apply ice packs to the face (15 minutes on, 15 minutes off) to minimize swelling
• Take prescribed medications including antibiotics, anti-inflammatory drugs, and pain relievers
• Eat soft, cool foods on the opposite side of the mouth
• Do not lift the lip to inspect the surgical site, as this can disrupt healing
• Avoid brushing the surgical area for the first 24 to 48 hours
• Do not smoke as this significantly impairs healing

Days 3–7

• Swelling peaks around day 2–3 and gradually improves
• Begin gentle salt water rinses after meals
• Resume gentle brushing near the surgical area with a soft brush
• Continue soft diet and avoid chewing on the treated side

Days 7–14

• Sutures dissolve or are removed
• Most swelling and discomfort resolve
• Gradually return to normal diet
• Attend follow-up appointment for evaluation

Long-Term Monitoring

• Follow-up X-rays at 6 months and 12 months to confirm bone healing
• Successful healing is demonstrated by progressive bone fill in the area where the periapical lesion was removed

Risks and Potential Complications

Swelling and Bruising

Post-operative swelling and sometimes bruising of the face are normal, particularly for upper front teeth procedures. Swelling is typically most pronounced on days 2 and 3 and resolves within one to two weeks.

Numbness

For lower teeth, temporary numbness of the lip or chin can occur if the surgery is near the mental nerve or inferior alveolar nerve. Permanent numbness is very rare with careful CBCT-guided planning.

Root Shortening

Removing 3 millimeters of the root tip reduces the overall root length. In most cases, this is clinically insignificant. However, teeth with already short roots may not be ideal candidates for apicoectomy.

Treatment Failure

While success rates are high, approximately 3 to 15 percent of apicoectomies may not fully resolve the infection. If this occurs, extraction and replacement is typically the next step.

Sinus Communication

Apicoectomy on upper back teeth near the maxillary sinus can occasionally create a temporary opening. This is managed with appropriate surgical technique and post-operative precautions.
