Study Notes

Developmental Lateral Periodontal Cyst

Definition: A non-inflammatory developmental cyst, found adjacent or lateral to a vital tooth's root.
Etiology: Originates from odontogenic epithelial rests on the side of an adjacent tooth's root. The exact cause of the epithelial proliferation isn't understood, it's not an inflammatory process.
Clinical Features:
- Age: Most common in people aged 40-60.
- Sex: Male to female ratio is 2:1.
- Site: Typically in the mandibular premolar/canine region, or maxillary lateral incisor region.
- Appearance: Usually asymptomatic, discovered during routine radiographic exams. May show a slight bulge if the cyst is on the labial surface of the root, but the overlying mucosa is typically normal. The related tooth remains vital.
- Complications: If infected, symptoms may mimic a lateral periodontal abscess.
Radiographic Features:
- Radiolucent area.
- Small size (seldom exceeding 1 cm in diameter).
- Possibly well-circumscribed, or have an opaque margin.

Botryoid Odontogenic Cyst

Definition: A developmental cyst, lined by non-keratinized epithelium. It's the multicystic form of the developmental lateral periodontal cyst, frequently occurring on the lateral side or between the roots of erupted teeth.
Etiology: Thought to originate from rests of the dental lamina, reduced enamel epithelium, or rests of Malassez.
Histopathologic Features:
- Lined by stratified squamous epithelium (thin, one or two layers).
- Nodular thickenings in some cysts, with a swirling appearance.
- Cells inside may exhibit clear cytoplasm due to glycogen accumulation.
- Possible parakeratin/orthokeratin formation in the lining.
- Inflammatory cells might be present in the cyst wall, but this is a secondary phenomenon if it becomes infected.

Developmental Gingival Cyst of Adulthood

Definition: A non-inflammatory developmental cyst occurring on the gingiva, adjacent to a vital tooth. It's the gingival equivalent of the lateral periodontal cyst.
Etiology: Arises from remnants of dental lamina within soft tissue (epithelial rests of Serre's).
Clinical Features:
- Age: Frequently diagnosed in 40-60-year-olds.
- Sex: Affects both sexes equally.
- Appearance: A small, well-circumscribed, painless swelling on gingiva (less than 1 cm in diameter). Can involve the free or attached gingiva, and sometimes the gingival papilla. Larger lesions might show bluish discoloration due to bone erosion.
Radiographic Features: Does not typically show up on dental x-rays.
Histopathologic Features:
- Epithelial-lined cavity.
- Very thin, flattened stratified squamous epithelium, often non-keratinized.
- Possible keratin formation in some cases.

Gingival Cyst of the Newborn (Bohn's Nodules)

Definition/Preferred Name: Often called "Dental Lamina Cyst of Newborn" because the gingiva is related to teeth development, which isn't present in newborns.
Clinical Features:
- Appearance: Small, white, nodular lesions (a few millimeters in diameter) on the alveolar ridge.
- Origin: Develop from remnants of the dental lamina.
- Resolution: Usually resolve spontaneously, degenerating, rupturing and disappearing.
Histopathologic Features:
- Thin epithelial lining (two to three layers).
- Lumen often filled with desquamated keratin.
