Chapter 5 - Developmental Disorders
This type of disorder is caused by abnormalities in the genetic makeup of an individual and is transferred from parent to offspring.
What is an inherited disorder?
This syndrome is characterized by a broad chest, sparse body hair, and a webbed neck.
What is Turner Syndrome?
Defined as a new growth where cells exhibit uncontrolled proliferation
What is neoplasia?
A relatively common disease of unknown cause that affects periapical bone and is most commonly in the anterior mandible.
What is Periapical Cemento-Osseous Dysplasia
Can mimic dental and periodontal pain; be confusing to both the patient and clinician.
This soft tissue abnormality occurs when the lingual frenum is partially fused to the floor of the mouth.
What is ankyloglossia (tongue-tied)?
Bony overgrowth(s) on the midline of the hard palate.
What is torus palatinus (palatal tori)?
It invades and destroys surrounding tissue and has the ability to spread throughout the body.
What is malignant tumor?
The abnormal and disordered production of cementum and bone.
What is dysplasia?
Pathologic condition involving the fifth cranial nerve that is characterized by a unilateral sharp, shooting, knifelike, or electric shock-type pain.
What is Trigeminal Neuralgia?
This structure produced enamel during orofacial development.
What is an enamel organ?
White, corrugated, soft, folds in the oral mucosa.
What is White Sponge Nevus (Cannon Disease/Familial White Folded Mucosal Dysplasia)?
An odontogenic tumor composed of mature enamel, dentin, cementum, and pulp tissue.
What is an odontoma?
What is Myofascial Pain and Dysfunction?
This is a developmental abnormality that results from the enamel organ invaginating (folding itself) into the crown of a tooth before maturation.
What is Dens Invaginatus (Dens in Dente)?
Large, pyramid-shaped molars with large pulp chambers that resemble the horns of a bull.
What is Taurodontism?
Tumor that appears as a slowly enlarging, nonulcerated, painless, dome-shaped mass.
What is pleomorphic adenoma?
A chronic metabolic bone disease with resorption, osteoblastic repair, and remineralization of involved bone.
What is Paget Disease of Bone?
Hypermobility in which the patient can relocate the mandible back into the glenoid fossa.
What is Subluxation?
This is an uncommon developmental anomaly that occurs when a single tooth germ attempts to divide to form two teeth.
What is gemination?
This syndrome is characterized by dwarfism, hypoplastic finger and toenails and the fusion of the anterior portion of the maxillary gingiva to the upper lip from canine to canine.
What is Ellis-Van Creveld Syndrome?
A benign tumor of mature fat cells.
What is a Lipoma?
A pseudocyst that consists of blood-filled spaces surrounded by multinucleated giant cells and fibrous connective tissue.
