6.
A periapical cyst can expand with osteoclastic bone resorption and is mostly located int he anterior maxilla.
Correct Answer
A. True
Explanation
A periapical cyst is a type of cyst that forms at the apex of a tooth due to inflammation or infection. It can cause bone resorption, which means that it can cause the bone surrounding it to be broken down by osteoclasts, a type of bone cell. This can lead to the expansion of the cyst. Periapical cysts are commonly found in the anterior maxilla, which refers to the front part of the upper jaw. Therefore, the statement that a periapical cyst can expand with osteoclastic bone resorption and is mostly located in the anterior maxilla is true.

9.
A dentigerous cyst is a proliferation of the enamel organ remant or reduced enamel epithelium.
Correct Answer
A. True
Explanation
A dentigerous cyst is indeed a proliferation of the enamel organ remnant or reduced enamel epithelium. This cyst forms around the crown of an unerupted tooth and is the most common type of developmental cyst associated with impacted teeth. It occurs when the enamel organ or reduced enamel epithelium continues to grow after the crown of the tooth is fully formed. This growth can lead to the formation of a fluid-filled sac around the tooth, causing potential complications if left untreated.
10.
A potential complication of a dentigerous cyst is a transformation of epithelial lining into an ameloblastoma.
Correct Answer
A. True
Explanation
A dentigerous cyst is a type of cyst that forms around an impacted tooth. It is lined with epithelial cells. In some cases, these cells can undergo a transformation and develop into an ameloblastoma, which is a benign but locally aggressive tumor that originates from the cells that form tooth enamel. This transformation is a potential complication of a dentigerous cyst, making the statement "True" correct.
11.
An eruption hematoma may appear following trauma of an eruption cyst where blood may appear in the tissue space.
Correct Answer
A. True
Explanation
An eruption hematoma may appear following trauma of an eruption cyst where blood may appear in the tissue space. This statement is true because an eruption hematoma is a common complication of an eruption cyst, which is a developmental cyst that forms around an erupting tooth. Trauma to the cyst can cause bleeding, resulting in the formation of a hematoma in the tissue space.

Satellite cysts (Daughter cells) account for a high rate of recurrence in an odontogenic keratocyst.
Correct Answer
A. True
Explanation
Satellite cysts, also known as daughter cells, are small cysts that form around the main odontogenic keratocyst. These satellite cysts are responsible for the high rate of recurrence in odontogenic keratocysts. When the main cyst is removed or treated, these satellite cysts can still remain and lead to the reoccurrence of the cyst. Therefore, the statement "Satellite cysts (Daughter cells) account for a high rate of recurrence in an odontogenic keratocyst" is true.
16.
Bifid ribs show up on a chest x-ray on a patient with Nevoid Basal Cell Carcinoma.
Correct Answer
A. True
Explanation
Bifid ribs refer to a condition where the ribs are split into two branches at their anterior ends. This abnormality can be seen on a chest x-ray of a patient with Nevoid Basal Cell Carcinoma (NBCC). NBCC is a genetic disorder that causes the development of multiple basal cell carcinomas on the skin. Bifid ribs are one of the physical features associated with NBCC, along with other skeletal abnormalities. Therefore, it is true that bifid ribs can be observed on a chest x-ray of a patient with NBCC.
17.
A calcifying odontogenic cyst is also called Gorlin's cyst and is more present in the maxilla.
Correct Answer
A. True
Explanation
A calcifying odontogenic cyst is indeed also known as Gorlin's cyst, which is a rare type of cyst that forms in the jawbone. It is typically found more commonly in the maxilla, which is the upper jaw. Therefore, the statement "A calcifying odontogenic cyst is also called Gorlin's cyst and is more present in the maxilla" is true.
18.
In a calcifying odontogenic cyst, Calcifications show up as salt and pepper radiolucencies from ghost cells on an xray.
Correct Answer
A. True
Explanation
Calcifying odontogenic cysts are benign cystic lesions that can occur in the jawbones. These cysts are characterized by the presence of ghost cells, which are degenerated epithelial cells that have undergone calcification. On an x-ray, these calcifications appear as salt and pepper radiolucencies, meaning that they show up as scattered dark and light spots. Therefore, the statement that calcifications in a calcifying odontogenic cyst show up as salt and pepper radiolucencies from ghost cells on an x-ray is true.

An aneurysmal bone cyst occurs more commonly on the mandible and bruit is not heard on auscultation.
Correct Answer
A. True
Explanation
An aneurysmal bone cyst is a benign bone tumor that commonly occurs on the mandible. It is characterized by a blood-filled cystic lesion that can cause pain and swelling. Auscultation refers to the act of listening to internal sounds of the body using a stethoscope, and bruit refers to an abnormal sound heard during auscultation. In the case of an aneurysmal bone cyst, bruit is not typically heard on auscultation. Therefore, the statement "An aneurysmal bone cyst occurs more commonly on the mandible and bruit is not heard on auscultation" is true.
25.
A traumatic bone cyst shows interradicular scalloping between roots.
Correct Answer
A. True
Explanation
A traumatic bone cyst is a benign bone lesion that typically occurs in the mandible or maxilla. It is characterized by a cystic cavity filled with serous or hemorrhagic fluid. One of the radiographic features of a traumatic bone cyst is interradicular scalloping, which refers to the concave depressions or scallops seen between the roots of the affected teeth. This is due to the expansion of the cystic cavity and the resorption of the surrounding bone. Therefore, the statement that a traumatic bone cyst shows interradicular scalloping between roots is true.
26.
A depression in the posterior lingual mandible is show with a traumatic bone cyst.
Correct Answer
B. False
Explanation
Static Bone Cyst
27.
A static bone cyst is due to a hyperplastic salivary gland.
Correct Answer
A. True
Explanation
A static bone cyst is a rare benign bone tumor that typically occurs in the mandible or maxilla. It is characterized by a fluid-filled cavity within the bone. The exact cause of a static bone cyst is unknown, but it is believed to be associated with a hyperplastic salivary gland. This suggests that the overgrowth of salivary gland tissue may contribute to the formation of the cyst. Therefore, the statement "A static bone cyst is due to a hyperplastic salivary gland" is true.

A focal osteoporotic bone marrow defect is usually from poor healing in the elderly and has radiolucencies where hematopoiesis is normally seen (angle of mand. and max. tuberosity).
Correct Answer
A. True
Explanation
A focal osteoporotic bone marrow defect is a condition commonly seen in the elderly where there is poor healing. This defect is characterized by radiolucencies, which are areas of decreased density, typically found in the angle of the mandible and the maxillary tuberosity. This is true because osteoporosis, which is a condition characterized by decreased bone density, can lead to poor healing and the formation of these radiolucencies in these specific areas.
29.
Abnormal healing following a tooth extraction may be responsible for a focalosteoporotic bone marrow defect.
Correct Answer
A. True
Explanation
Abnormal healing following a tooth extraction can lead to a focal osteoporotic bone marrow defect. This means that the area where the tooth was extracted may experience abnormal bone healing, resulting in a weakened bone structure. This can lead to a localized osteoporotic condition in the bone marrow, causing a focal osteoporotic bone marrow defect. Therefore, the statement "Abnormal healing following a tooth extraction may be responsible for a focal osteoporotic bone marrow defect" is true.

The thyrglossal tract cyst is the most common development cyst of the neck.
Correct Answer
A. True
Explanation
The thyroglossal tract cyst is indeed the most common developmental cyst of the neck. This cyst forms when remnants of the thyroglossal duct, which is a structure that connects the thyroid gland to the tongue during fetal development, fail to fully disappear. These cysts typically present as painless, midline neck masses that move with swallowing or protrusion of the tongue. They are most commonly found in children and young adults. Treatment usually involves surgical removal of the cyst and any associated thyroglossal duct remnants to prevent recurrence.
