Professor Fatusi at the 343rd inaugural lecture of the Obafemi Awolowo University, Ile-Ife, Osun State, said odontogenic
infections, which are infections arising from teeth and the teeth-supporting structures, can be fatal.
Cementoblastoma, osteoid osteoma, cemento-osseous lesions, adenomatoid odontogenic
tumor, calcifying epithelial odontogenic
tumor, and ameloblastic fibro-odontoma were also considered in the differential diagnoses.
Tumor Dimensions (Core and Noncore).--Owing to the intraosseous nature of odontogenic
lesions, reference to any imaging studies or consultation with a radiologist is recommended in order to achieve the best interpretation of maximum tumor dimension, combining macroscopy, specimen or clinical radiology, and microscopy.
A differential diagnosis is also possible where DCs can be distinguished from odontogenic
keratocyst, ameloblastic fibroodontoma, ameloblastic fibroma, calcifying epithelial odontogenic
tumor, adenomatoid odontogenic
tumor, and unicystic ameloblastoma (7).
There are only a handful of tumour markers that can be used by pathologists for diagnosis of odontogenic
tumours, and many other potential markers are constantly under development.
Impacted teeth may lead to common complications like carious lesions of the impacted or adjacent tooth, periapical infection, periodontal disease and pathology like cyst and tumor.9 Common odontogenic
cysts and tumors include dentigerous cyst, calcifying odontogenic
cyst, ameloblastoma, adenomatoid odontogenic
keratocyst, calcifying epithelial odontogenic
tumor, and odontoma.10 Review of literature states that cystic or neoplastic lesions are seen in 16% of impacted teeth and is most common finding during the second and third decades of life.11 The most frequent lesion associated with impacted teeth is the dentigerous cyst.12
lesion: Fifty- four OLs were detected in 39 (19.5%) of all cases (16 female and 23 male).
The most commonly implicated factor reported for CNF in the head and neck region is odontogenic
infection or post-extraction infection.
The information in the medical records included the following: female and male patients aged 0-18 years who were arranged into 0-4 years, 5-9 years, 10-14 years, 15-18 years age groups, and those who were diagnosed with some type of oral and maxillofacial pathology, divided as follows: head/neck cystic lesions, temporomandibular joint (TMJ) lesions, infectious lesions, benign head and neck tumor, malignant head and neck tumor, benign odontogenic
tumor, and those admitted to the HOMI in the period between January 2006 and December 2014.
The majority of ameloblastomas derive from the odontogenic
apparatus (ie, epithelium, enamel organ and its derivatives or remnants), or less commonly from the lining of a dentigerous cyst.
lesions in a pediatric population: Review of the literature and presentation of 745 cases.
keratocyst (OKC) is officially known as a true benign tumor, and it is aggressive in nature.
