Cyst | Ortho-Keratinized Odontogenic Cyst| Part 4 | Oral Pathology| BDS 3rd Year| Handwritten Notes.

Ortho-keratinized odontogenic cyst (OOC) is a developmental cyst of odontogenic origin. It is a distinct entity from odontogenic keratocyst (OKC) and shows a less aggressive behavior. Key Features: • Origin: Derived from dental lamina remnants. • Histology: The cyst lining is orthokeratinized stratified squamous epithelium (shows a well-defined granular layer and orthokeratin on the surface). • Epithelium thickness: Uniform, usually 4–9 cell layers thick. • Inflammation: Minimal or absent unless secondarily infected. • Clinical features: Often asymptomatic, may present as a slow-growing jaw swelling. • Location: Most common in the posterior mandible. • Radiology: Unilocular radiolucency, well-defined borders. • Behavior: Less recurrence rate compared to OKC. • Treatment: Enucleation with minimal recurrence. Note: It is important to differentiate OOC from OKC due to differences in biological behavior and recurrence risk. . . . histophysiology of tooth development sensory pathways physiology skeletal muscle histology development of cerebellum embryology sociotechnical systems theory brain development scholarship appendicular skeleton anatomy memorization ... parasympathetic receptors classification of skeletal system vaccine development biochemistry
