Gardner Syndrome

Presence of osteomas in various bones of the skull

Peutz-Jeghers syndrome

mucosal pigmentation, associated with gastrointestinal polyposis.

periapical cemento-osseous dysplasia (cementoma)

Asymptomatic fibro-osseous lesion

Type I Amelogenesis Imperfecta

incomplete or improper development of the enamel tissue, this picture shows the pitting on the labial surface

Paget diseaseEnlargement of the Maxilla with

chronic metabolic bone disease

Pleomorphic adenoma (benign mixed tumor)

-A benign salivary gland tumor

-90% of all salivary gland tumors

-The most common extraoral location is the parotid gland; the most common intraoral location is the palate

Cementoblastoma

Odontogenic tumor of cementoblasts that resembles another odontogenic tumor but has direct attachment to a tooth

compound odontoma

- Small radiopaque masses

- Usually in the anterior jaw

- Resemble an accumulation of small teeth

Mandibulofacial Dysostosis

Also called Treacher Collins Syndrome, it is a genetic disorder that affects the development of the facial structure. Characterized by a fish-like mouth (high palate, downward sloping of the lip commissures, and an open-bite). Deafness results from a lack of otic ossicles.

Ameloblastoma

Benign but aggressive tumor w sig recurrence

Most common in post mand but can be in the ant

Most common true odontogenic tumor

multilocular radiolucency (soap bubble)

often assoc w/ impacted tooth

Cleidocranial dysplasia

supernumerary teeth extracted resulting from the cranium developing into a mushroom shape because the fontanelles remain open

pegged maxillary lateral incisors

Mandibular lesion

seen radiographically in a patient with hyperparathyroidism

-radiolucencies also called brown tumors

osteonecrosis

death of bone tissue associated with bisphosphonate therapy

Macroglossia

Enlarged tongue; associated with acromegaly

exuberant form of periapical cemento-osseous dysplasia, may involve entire jaw, African American middle aged women

Cyclic Neutropenia

ulcerated gingivitis is characterized by a decrease in the number of circulating neutrophilic leukocytes

Verrucous Carcinoma

Specific type of squamous cell carcinoma that is separated from other squamous cell carcinomas because it has a much better prognosis

Central Giant Cell Granuloma

May present as a multilocular radiolucency, most common on the anterior segments

pernicious anemia

lack of mature erythrocytes caused by inability to absorb vitamin B12 into the bloodstream

iron deficiency anemia

anemia resulting when there is not enough iron to build hemoglobin for red blood cells

sickle cell anemia

a genetic disorder in which erythroctyes take on an abnormal curved or "sickle" shape

Calcifing odontogenic cyst

most common >40

may have calcifications

squamous cell carcinoma

Lipoma

a benign, slow-growing fatty tumor located between the skin and the muscle layer

Candidiasis (Thrush)

Thick, white, raised patches in the mouth (this is probably caused from not cleaning the denture)

Central Giant Cell Granuloma (CGCG)

Non-neoplastic bone growth. Etiology unknown. Most commonly seen in females 30 years and younger. Treatment based on level of destruction. Corticosteroid injections reverse some CGCGs.

angioedema

The diffuse swelling caused by the increased permeability of deeper blood vessels depicted in the image below is called

Down Syndrome (Trisomy 21)
