REVIEW
R Boeddinghaus, A Whyte
Maxillofacial imaging encompasses radiology of the teeth and jaws, including the temporomandibular joints. Modalities used include intra-oral radiographs, panoramic tomography, cephalograms, cone-beam computed tomography, computed tomography, magnetic resonance imaging, ultrasound, and radionuclide imaging. Common indications for imaging are impacted and supernumerary teeth, dental implants, inflammatory dental disease, and fibro-osseous lesions, cysts, and masses of the jaws. Osteonecrosis of the jaws may follow radiotherapy or the use of bisphosphonates and other drugs...

Dentigerous cysts are the most common developmental odontogenic cysts of the jaw, which usually occur in the second and third decade of life. It is most frequently associated with impacted mandibular third molar teeth and impacted canines. Bilateral/multiple dentigerous cysts are rare and typically associated with developmental syndromes. Non-syndromic dentigerous cyst occurring bilaterally or involving both arches at the same time is very rare. Here, we discuss the review of literature with a case of unusual occurrence of non-syndromic bi-maxillary dentigerous cysts in a child...

The glandular odontogenic cyst (GOC), though rare, has now become a well known entity. The frequency of GOC ranges from 0.012% to 1.3% of all jaw cysts and its worldwide prevalence is 0.17%. The GOC's microscopic features have been well documented, and are also included in the list of World Health Organization. We report a case of GOC presenting as a unilocular osteodestructive lesion of anterior mandible in a 28-year female. The diagnosis was made on the basis of characteristic histological findings.

PURPOSE: Cysts are common pathologic entities in the oral and maxillofacial region. Enucleation is commonly used for treatment and is occasionally followed by bone grafting. However, no studies have evaluated factors affecting the failure of grafts used for cystic defects in the oral and maxillofacial region. Therefore, the present study was conducted to determine the risk factors for postoperative graft failure in patients treated with cyst enucleation and simultaneous bone grafting...

A small radiolucent area in the mandible was discovered in a 58-year-old woman with no oral complaints. The patient's history included only hypertension. The lesion was considered as an inflammatory cyst and was enucleated. Three months later, a CT revealed the presence of a cyst-like lesion in the mandible with thin expanded buccal cortical plate, localized erosion, and a polylobate appearance on the lingual aspect of the cortical plate. The histological diagnosis of the lesion was central giant-cell granuloma (CGCG)...

Dentigerous or follicular cysts of odontogenic origin are innocuous benign cysts that are often linked with the crowns of permanent teeth. A dentigerous cyst circumventing permanent teeth fails to erupt and is often displaced into ectopic positions in the upper and lower jaw in the maxillofacial region. In the maxilla or upper jaw region, the impacted teeth are often displaced and/or shift into the maxillary sinus and apart from the nasal septum, mandibular condyle, coronoid process and the palate, to harbour such ectopic eruptions of teeth...

Tooth eruption is defined as the movement of a tooth from its site of development within the alveolar process to its functional position in the oral cavity. The process of tooth eruption can be divided into different phases: pre-eruptive bone stage, alveolar bone stage, mucosal stage, preocclusal stage, occlusal stage and maturation stage. Any disturbance in these phases can lead to eruptive anomalies. The incidence of unerupted teeth is usually higher among permanent teeth than among deciduous ones. Of the primary teeth reported as unerupted, second deciduous molars are the teeth most frequently involved, followed by primary central incisors...

Primary intraosseous squamous cell carcinoma (PIOSCC) derived from a odontogenic cyst is a rare form of odontogenic carcinoma. The incidence of carcinomas arising from odontogenic cysts is particularly uncommon and is reported to occur in 1-2 individuals for every 1,000 cases. The present case describes a 25-year-old man who was initially diagnosed with a chronically infected odontogenic cyst of the mandible. Biopsy and subsequent histology revealed the presence of squamous cell carcinoma. Therefore, neck dissection and hemimandibulectomy were performed...

Odontogenic cysts and osseous lesions are often seen as challenging diagnostic lesions but the majority of them are easily classified. This article outlines the diagnostic features required for separating the most common of odontogenic cysts and select osseous lesions of the jaws. Clinical and radiographic findings of these jaw lesions often lead to a differential diagnosis that only the histologic findings will clarify. Dentigerous cyst, keratocystic odontogenic tumor, and certain ameloblastomas that have cystic change, may have identical radiographic findings, with only separation by their specific histologic features leading to the significantly different treatments required for each...

The Odontogenic keratocyst (OKC) is a cystic lesion of the jaws, which has high growth and recurrence rates compared to other cysts of the jaws (for instance, radicular cyst, which is the most common jaw cyst type). For this reason OKCs are considered by some to be benign neoplasms. There exist two sub-types of OKCs (sporadic and syndromic) and the ability to discriminate between these sub-types, as well as other jaw cysts, is an important task in terms of disease diagnosis and prognosis. With the development of digital pathology, computational algorithms have become central to addressing this type of problem...

Giant cell tumor (GCT) of bone is a giant-cell-rich bony lesion associated with abundant multinucleated osteoclast-type giant cells. It is a primary neoplasm of bone with characteristic clinical, radiological, and pathological features. It is an expansive and lytic lesion without periosteal reaction and prominent peripheral sclerosis. Giant cells are also seen in other diseases like giant cell granuloma of the jaws, traumatic bone cyst, aneurysmal bone cyst, and jaw tumor of hyperparathyroidism. We present a unique case of GCT of palate in a 30-year-old female...

OBJECTIVES: Orofacial cysts are broadly divided into odontogenic and nonodontogenic types, epithelial or non-epithelial, and developmental or inflammatory in origin. The odontogenic cyst is an osseous-destructive lesion that most commonly affects the jaw. It is formed by activation of odontogenic cell rests entrapped within the bone or gingival tissue of the jaws, such as the epithelial remains of Malassez, the dental lamina (cell rests of Serres), or the enamel organ. METHODS: We performed a retrospective study of all histologically diagnosed cysts of the orofacial region seen at the Maxillofacial clinic of the Ahmadu Bello University Teaching Hospital, Nigeria, between January 2003 and December 2012...
