Exam 2 (CH 5 & 6 Crash course) Flashcards
is characterized by well-defined, pear-shaped radiolucency, and is believed to be of odontogenic epithelial origin. When it is large enough, divergence of the roots of adjacent teeth can result.
Globulomaxillary
Often referred to as a pseudocyst because it is not a pathologic cavity and is not lined with epithelium. It is characterized by a well defined radiolucency in the posterior region of the mandible inferior to the mandibular canal, which is caused by a lingual depression in the mandible containing salivary gland tissue.
Stafne defect
(Static bone cyst)
Glandular odontogenic cyst are most common in anterior maxilla and posterior mandible.
True
False
True
A failure or disturbance that occurs during the process of prenatal development that can result in a lack, excess, or deformity of a body part. Also called developmental anomaly.
Developmental disorder
an odontogenic developmental cyst with a unique histologic appearance. The lumen is lined by epithelium that is 8 to 10 cell layers thick and surfaced by parakeratin. The basal cell layer is palisaded and prominent; the interface between the epithelium and the connective tissue is flat. This cyst has a higher recurrence rate than many other odontogenic cysts.
Odontogenic keratocyst
A cyst that forms around the crown of an unerupted or developing tooth. Also call follicular cyst.
Dentigerous
A complete or almost complete congenital lack of teeth.
Anodontia
Partial anodontia. The lack of one or more teeth.
Hypodontia
Globulomaxillary cyst is a cyst found between the roots of
Maxillary lateral incisor
&
cuspid
“Twinning”; when single tooth germ attempts to divide, resulting in the incomplete formation of two teeth; the tooth usually has a single root and root canal
Germination
Glandular odontogenic cyst are most common in
Anterior maxilla
&
mandible
______ is a rare developmental odontogenic cyst. Exhibit a distinctive microscopic appearance. Developmental; may cause enlargement of bone
Glandular odontogenic
“a tooth within a tooth” ; a developmental anomaly that results when the enamel organ invaginates into the crown of a tooth before mineralization. It is most commonly seen in the maxillary lateral incisor. Also call dens invaginatus
Dens in dente
Amelogenesis imperfecta is a broad group of condtions that affect the structural formation of the _________.
Enamel
A condition characterized by very large, pyramid-shaped molars with large pulp chambers and short roots.
Taurodontism
Located within the nasopalatine canal or the incisive papilla. It arises from epithelial remnants of the embryonal nasopalatine ducts. Also known as an incisive canal cyst.
Nasopalatine canal cyst
The incomplete or defective formation of enamel, resulting in the alteration of tooth form or color
Enamel hypoplasia
A mass of thyroid tissue located on the tongue away from the normal anatomic location of the thyroid gland. It is an uncommon developmental anomaly that results from the failure of primitive thyroid tissue to migrate from its developmental location in the area of the foramen cecum on the posterior portion of the tongue to its normal position in the neck. Also called ectopic lingual thyroid nodule.
Lingual thyroid nodule
Concrescence is a condition in dentistry in which two adjacent teeth are united by.
Cementum
Talon Cusp is an accessory cusp located in the area of
Cingulum in a maxillary or mandibular permanent incisor
(crown size is enlarged) – localized enlargement affecting one side of the orofacial structures.
Facial hemihypertophy
Disordered growth, alteration in size, shape and organization of adult cells or structures.
dysplasia
the most severe form of ectodermal dysplasia. Its major characteristics are hypodontia (less teeth), hypotrichosis (less hair), and hypohidrosis (less sweat).
Hypohidrotic ectodermal dysplasia
a condition characterized by a lateral incisor that is small and peg shaped or congenitally lacking, either unilaterally or bilaterally. Both primary and secondary dentitions can be affected, but mostly the latter.
Pegges lateral
Downs syndrome a type of abnormality in which ____________. This results in abnormal physical characteristics and mental impairment.
three of chromosome 21 are found instead of two
Downs syndrome is also known as
trisomy 21
a hereditary disease characterized by a cyclic decrease in the number of circulating neutrophils. The cycles occur in intervals of 21 to 27 days, and the episodes of neutropenia persists for 2-3 days.
Cyclic neutropenia
(chondroectodermal dysplsia) absent upper vestibule, serrated lower alveolar ridge, polydactyly, thinning of enamel. This best describes
Ellis-van Creveld syndrome
An inherited syndrome characterized by the presence of osteomas in various bones, especially in the frontal bone, maxilla, and mandible. Osteomas of the facial skeleton expand, obliterate the sinus, and cause facial asymmetry. Intestinal polyps are also present, which become malignant after the age of 30. Also known as familial colorectal polyposis.
Gardner syndrome
A disorder beginning in childhood characterized by progressive bilateral facial swelling that can occur in either the maxilla or mandible, with involvement of mandible being most common. The swollen jaws and raised eyes give a “cherublike” appearance and radiographs show multilocular radioluscent lesions.
Cherubism
An inherited disease characterized by marked destruction of the periodontal tissues of both dentitions, with premature loss of teeth and hyperkeratosis of palms of the hands and soles of the feet.
Papillon-Lefevre syndrome
Is a genetic disorder characterized by the growth of tumors on the nerves. The disease can also affect the skin and cause bone deformities
Neurofibromatosis of Von Reckinghausen
an autosomal dominant inherited disorder characterized by intestinal hamartomatous polyps in association with a distinct pattern of skin and mucosal macular melanin deposition.
Peutz-jeghers syndrome
An inherited disorder of bone growth that results in very short stature (dwarfism).
