Gingival cyst is a benign, developmental odontogenic cyst that arises from remnants of the dental lamina located in the gingiva (gum tissue). It typically presents as a small, painless swelling and is most commonly found in either newborns or adults, depending on the subtype.

Overview

Gingival cysts are non-inflammatory cystic lesions that originate from epithelial remnants left behind during tooth development. They are usually superficial, well-circumscribed, and slow-growing.

Two main types are recognized:

• Gingival cyst of the newborn
• Gingival cyst of the adult

These lesions differ in age of onset, location, and clinical behavior.

Classification

Gingival cyst of the newborn

Also known as:

• Epstein pearls
• Bohn's nodules

These are small, white or yellow nodules found on the gums of newborn infants.

Gingival cyst of the adult

Occurs later in life and is typically seen in adults between the ages of 40 and 60.

Epidemiology

• Gingival cysts of the newborn are common and often underreported
• Adult gingival cysts are relatively rare
• No strong sex predilection
• Most adult cases occur in the anterior mandible

Etiology

Gingival cysts arise from:

• Residual epithelial cells from the dental lamina
• Developmental remnants trapped in gingival tissue

They are not associated with infection or trauma.

Pathophysiology

During odontogenesis (tooth development), the dental lamina forms the basis for tooth formation. After tooth development, remnants of this structure may persist.

These epithelial remnants can:

• Proliferate
• Form a cystic cavity
• Accumulate fluid or keratin

This results in a small cystic lesion within the gingiva.

Signs and symptoms

Gingival cyst of the newborn

• Small (1–3 mm)
• White or yellow nodules
• Located on alveolar ridges
• Asymptomatic
• Often multiple

Gingival cyst of the adult

• Small, dome-shaped swelling
• Usually less than 1 cm
• Located on attached gingiva
• Most commonly in mandibular canine-premolar region
• Painless
• May appear bluish or translucent

Diagnosis

Diagnosis is typically clinical but may require confirmation.

Clinical examination

• Inspection of lesion size, color, and location
• Assessment of symptoms

Imaging

Usually not required, but may be used to rule out deeper lesions.

Histopathology

Microscopic features include:

• Thin epithelial lining
• Non-keratinized or keratinized epithelium
• Clear cells containing glycogen
• Minimal inflammation

Differential diagnosis

Conditions that may resemble gingival cyst include:

• Mucocele
• Fibroma
• Periodontal abscess
• Lateral periodontal cyst
• Odontogenic keratocyst
• Peripheral ossifying fibroma

Treatment

Gingival cyst of the newborn

• No treatment required
• Spontaneously resolves within weeks or months

Gingival cyst of the adult

• Simple surgical excision if needed
• Observation if asymptomatic

Prognosis

The prognosis is excellent.

• Recurrence is rare
• No malignant transformation
• Complete resolution after treatment

Complications

Complications are uncommon but may include:

• Enlargement causing discomfort
• Cosmetic concerns
• Rare recurrence after incomplete excision

Prevention

There are no specific preventive measures, as gingival cysts are developmental in origin.
