What is Microsurgical Endodontics?

Microsurgical endodontics is the modern form of apicoectomy combining the operating microscope, micro-instruments, ultrasonic retro-preparation and bioceramic root-end filling materials to treat persistent periapical pathology.

Indications include persistent or recurrent periapical lesions after adequate non-surgical retreatment, anatomic obstacles (calcifications, ledges, separated instruments), iatrogenic perforations and biopsy of suspicious lesions.

The procedure typically involves a microsurgical flap, osteotomy, root-end resection at low bevel angle, ultrasonic retro-preparation and retrograde filling with bioceramic cements (e.g., MTA, Biodentine, Bioceramic putty); reported success rates exceed 90% with modern protocols.

Symptoms

Persistent apical tenderness on percussion
Recurrent sinus tract or fistula
Persistent or growing periapical radiolucency
Localized swelling over previously treated tooth
Pain with biting after root canal therapy
Failed orthograde retreatment with adequate quality
Deep periodontal pocket associated with apical lesion

Risk Factors

Inadequate prior root canal obturation
Procedural errors (perforations, ledges, separated instruments)
Complex root canal anatomy and isthmuses
Coronal leakage and recurrent caries
Persistent intracanal infection (Enterococcus faecalis biofilm)
Cracked root or vertical root fracture
Smoking and uncontrolled diabetes affecting healing

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Persistent symptoms after well-performed root canal
  • Recurrent fistula or abscess
  • Increasing periapical radiolucency on follow-up
  • Cases where orthograde retreatment is impractical
  • Suspected vertical root fracture requiring biopsy
  • Need for cone-beam CT evaluation
  • Discussion of microsurgery versus extraction and implant

Treatment Methods

01
Cone-beam computed tomography for three-dimensional planning
02
Pre-operative antimicrobial and analgesic protocol
03
Microsurgical flap design (papilla-base, sulcular)
04
Osteotomy and root-end resection with minimal bevel
05
Ultrasonic retro-preparation along the canal axis
06
Bioceramic retrograde filling (MTA, Biodentine or bioceramic putty)
07
Long-term radiographic and clinical follow-up of periapical healing

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
