Radiopacities: separate, single or multiple

Question Answer
T/F: further evaluation is necessary for thyroid cartilage calcificationFalse
T/F: further evaluation is necessary for arterial calcificationTrue
T/F: Carotid calcification is usually unilateral... even though it can be bilateralTrue
T/F: Thyroid cartilage calcification is most likely bilateralTrue
T/F: Thyroid cartilage calcification is usually unilateralFalse (bilateral)
T/F: Carotid calcification is usually bilateral and rarely unilateralFalse (usually uni- sometime bi-)
Carotid calcifications is more common in what gender, what age and with what systemic condition?Males, 50+, Hyperlipidemia
Calcifications of carotid artery and thyroid cartilage can be hard to distinguish... if the patient is young (30's or younger) which is it?Thyroid cartilage (hyperlipidemia, causative factor for arterial calcification, has not had time to develop by this age)
___% of carotid calcification seen on pan represent sever stenosis of the vessel (>50% stenosis)20%
T/F: the extent of stenosis from carotid calcification can be determined from a panoramic radiographFalse
T/F: Follow-up with a physician is indicated if carotid calcification is observed on a panoramic radiographtrue
T/F: Follow-up with a physician is indicated if thyroid cartilage calcification is observed on a panoramic radiographfalse (but it is for carotid calcification)
Tonsilloliths Usually appear as cluster of small, illdefined radiopacities where on a pan?Mid-ramus (immediately inferior to alveolar canal)
Treatment indicated for tonsillolithsno treatment (as long as asymptomatic)
calcification around the head and neck that appear with pop-corn appearance, irregular but well-definedDystrophic Lymph node Calcification
most common duct to find salivary stonesWharton's duct (submandibular gland duct)
Most common salivary gland for salivary stones (aka sialoliths)Submandibular
Nidus for rhinolith is usually ___-ogenous, while Nidus for antrolith is usually ____-ogenousExogenous; Endogenous
The styloid process normally varies from ___ to ___ cm in length. it is considered elongated when > _________ cm0.5-2.5 cm; 3 cm
Calcification of the stylohyoid ligament radiographically can represent ____ of the ligament or _____ of the processmetaplasia of ligament; hyperplasia of process
T/F: patients that show radiographically of complete calcification from styloid process to stylo-hyoid ligament to hyoid bone have eagles syndromeFalse (only have eagle's syndrome if they also have pain)
Eagle's syndrome pain is thought to come from ossified complex and scar tissue impinging on which 5 cranial nerves?5, 7, 9, 10 and 12 (these are the possibilities)
which is more common... carotid artery syndrome or classic eagle's syndrome?Carotid Artery Syndrome
steroid or lidocaine injections into the tonsillar fossa is recommended initially as a conservative treatment for what condition?Eagle's Syndrome
believed to be that cause of exostosesOcclusal forces
what is the most common type of exostoses?Torus Palatinus
histologically the same as exostoses... but it is a benign tumor of boneOsteoma
Osteomas commonly occur where?Mandibular angle and condyle
Multiple osteomas* (and often multiple impacted teeth or supernumerary teeth) are associated with what genetic disease?Gardner syndrome
genetic disease with colonic and extracolonic intestinal polyps that exhibit malignant transformation into adenocarcinoma (multiple osteomas of the jaw)Gardner syndrome
What is the most common odontogenic tumor?Odontoma
rare genetic bone disorder with short stature, large head, delayed closure of sutures and fontanels, that can meet shoulder forward until they meet in the midlineCleidocranial Dysplasia
Dental findings of this rare genetic disorder include: Narrow, high-arched palate, increased clevalence of cleft palate, prolonged retention of primary teeth, small or absent maxillary sinuses, and numerous unerupted permanent and supernumerary teethCleidocranial dysplasia

what is it?

Question Answer
Radiopacity with vertical linear distribution, irregular in shape and usually multiple...Posterior and inferior to angle of mandible, adjacent to C3/C4 or above/below greater horn of hyoid boneAtherosclerotic clarification
cluster of small, ill-defined radiopacities showing in the mid-ramus area or just inferior to the IACTonsollith (palatine tonsil calcification)
Calcification that can look like a retained maxillary root tipAntrolith (sinus stone)
pain in pharynx on swallowing, when turning head, or opening mouth ... with a history of trauma such as tonsillectomyClassic Eagle's Syndrome
pain in pharynx on swallowing, when turning head or opening mouth... with no history of traumaCarotid Artery Syndrome (subtype of eagle's syndrome)
Symptoms are produced by mechanical irritation of carotid sympathetic nerve tissue producing regional carotidynia (radiating up to mandible or eye)Carotid artery syndrome (subtype of Eagle's syndrome)
Benign localized bony protuberance arising from cortical plate of boneExostoses (torii are a subtype of exostoses)
dense radiopaque shadow on pan below or attached to hard palateTorus palatinus (palatine torus)
type of odontogenic tumor that has dentin, enamel, pulp and pdlOdontoma
