Oral Med Final Exam Radiographic Lesions Ch 20

Periapical or dental granuloma refers to a radiolucent lesion often seen at the apex of a tooth root, caused by chronic periapical inflammation. Ameloblastoma, Odontogenic keratocyst, and Nasopalatine duct cyst are different types of odontogenic cysts and tumors that present with distinct radiographic features.

A periapical or dental granuloma is a common radiolucent lesion that forms at the apex of a tooth root due to chronic inflammation. Unlike dental cysts, which are lined with epithelium, granulomas lack a lining. Periodontal abscesses are localized collections of pus in the periodontal tissues, while odontogenic keratocysts are benign but locally aggressive jaw cysts.

A periapical or dental granuloma is a localized mass of chronically inflamed granulation tissue that can lead to bone resorption, pain, and sensitivity in the affected tooth. It is a common condition in endodontics.

Periapical cysts are the most common jaw cysts that are usually associated with non-vital teeth and share similarities with periapical granulomas. The other options, dental abscess, dentigerous cyst, and radicular cyst, are different conditions that do not match the description provided.

A pseudocyst with these characteristics is indicative of an aneurysmal bone cyst, which is a benign bone lesion commonly found in the posterior mandible and can appear as a soap bubble on radiograph.

A traumatic bone cyst or simple bone cyst appears as a well-defined radiolucent lesion, commonly found in the jaws. It is usually asymptomatic and typically seen in younger individuals. Other options like ameloblastoma, osteosarcoma, and fibrous dysplasia present with different radiographic features and clinical presentations.

A traumatic bone cyst is characterized by its scalloped, clear radiolucent lesion around the roots of teeth due to past trauma or calcium deficiency. Dentigerous cyst, osteosarcoma, and ameloblastoma present with different clinical and radiographic features.

Cemento osseous dysplasia is a benign condition typically found in the jaws, characterized by a proliferation of fibro-osseous tissue. Fibrous dysplasia, osteosarcoma, and central giant cell granuloma are different pathological conditions with distinct features.

Cemento osseous dysplasia is a benign fibro-osseous lesion that commonly occurs in the jaw. Other conditions such as amalgam tattoo, apical granuloma, and odontogenic myxoma present different clinical and histological features.

Osteomyelitis is an infection of the bone, which appears as a radiolucent lesion on imaging. Cysts, fibrous dysplasia, and chondrosarcoma are other types of bone lesions that may appear radiolucent but have different characteristics and etiologies.

Osteomyelitis is an infection of the bone, commonly caused by bacteria. It can occur as a result of fractures, trauma, or surgical procedures. Arthritis, bursitis, and tendonitis are inflammatory conditions but are not typically associated with acute infections from fractures, trauma, or surgery.

A lateral periodontal cyst appears as a well-defined radiolucent lesion in the lateral periodontal area of the tooth. It is important to differentiate it from other radiolucent lesions such as dental abscess, periapical cyst, and ameloblastoma for accurate diagnosis and treatment.

The image shows a lateral periodontal cyst, which is a specific type of radiolucent lesion commonly found in the periodontal tissues. Radicular cysts, dentigerous cysts, and static bone cavities are different types of lesions with distinct characteristics.

Lateral periodontal cysts are most frequently located on the lateral surface of teeth in the maxillary and mandibular canine premolar region, which distinguishes them from other types of cysts that may occur in different locations within the oral cavity.

Dentigerous cyst is a specific type of radiolucent lesion commonly found around the crowns of unerupted or developing teeth. Periapical cyst, ameloblastoma, and radicular cyst are different types of radiolucent lesions with distinct characteristics and locations.

Dentigerous cyst is a developmental cyst that forms around the crown of an unerupted tooth, accumulating fluid and potentially causing displacement or root resorption. It is the most common type of developmental cyst in the oral cavity.

An eruption cyst is a benign, non-pathological cyst that occurs in children when a tooth is erupting. It appears as a translucent blue swelling over the unerupted tooth.

Eruption cysts are a variant of dentigerous cysts and are usually painless, found around unerupted teeth. They may resolve on their own but sometimes need help for eruption. Dentigerous cysts, periapical cysts, and radicular cysts are different types of cysts with distinct characteristics.

Radiolucent lesions are commonly seen in the field of dentistry and it is important to differentiate between them. In this case, odontogenic keratocyst is a specific type of radiolucent lesion that originates from the dental lamina. Periapical cyst, dentigerous cyst, and radicular cyst are other types of radiolucent lesions, each with their own distinct characteristics and origins.

Odontogenic keratocyst is a cystic lesion originating from dental lamina remnants, commonly seen in the posterior mandible. It has a high recurrence rate even after surgical removal. Ameloblastoma, dentigerous cyst, and periapical cyst are other common odontogenic cysts but do not have the same characteristics as odontogenic keratocyst in terms of association with nevoid basal cell carcinoma syndrome and high recurrence rate.

The primordial cyst is a type of odontogenic cyst that forms before the tooth's calcification process in the 3rd molar region. It is typically painless and asymptomatic.

The correct answer is calcifying odontogenic cyst. Dentigerous cyst, keratocystic odontogenic tumor, and ameloblastoma are different types of odontogenic lesions with distinct histological features and clinical presentations.

The correct answer refers to a specific type of cyst with unique histological features.

The correct term for this radiolucency pattern is a globulomaxillary cyst, which is a benign odontogenic cyst typically found between the maxillary lateral incisor and canine. Dentigerous cyst, Nasopalatine duct cyst, and Lateral periodontal cyst are different types of cysts with distinct characteristics and locations in the oral cavity.

The correct answer refers to a radiolucent lesion commonly seen in the nasopalatine canal area, while the incorrect answers are different types of cysts found in distinct regions of the jaw.

Nasopalatine canal cyst is a common non-odontogenic cyst that usually presents in the anterior maxilla with a heart-shaped radiolucency. Dentigerous cyst, ameloblastoma, and odontogenic keratocyst are odontogenic lesions that present differently and do not typically have heart-shaped radiolucencies.

Radiolucent lesions in the jaw can be identified by their characteristics on imaging studies. It is important to differentiate between different types of lesions based on their appearance to provide accurate diagnosis and appropriate treatment.

Adenomatoid odontogenic tumor is a well-defined benign odontogenic tumor, while the incorrect options are other types of odontogenic tumors with different characteristics and clinical presentations.
