What is an Odontoma?
Odontomas are the most common odontogenic tumours.
They are considered to be hamartomas rather than neoplasms, and are composed of the tissues native to teeth: enamel, dentin, cementum and pulp tissue.
They develop from epithelial and mesenchymal components of the dental apparatus, producing enamel and dentin..
What causes Hypercementosis?
The local factors implicated to cause hypercementosis are occlusal trauma,7 inflammation secondary to pulpal or periodontal disease, tooth mobility,2 repair of root fracture and transplantation of teeth.
What does Dilaceration mean?
Dilaceration is an abnormal bend in the root or crown of a tooth. Although the root is affected most frequently, the bend may occur anywhere along the length of the tooth and has been noted in various teeth throughout the dentition.
What is Amelogenesis imperfecta?
Amelogenesis imperfecta is a disorder of tooth development. This condition causes teeth to be unusually small , discolored, pitted or grooved, and prone to rapid wear and breakage. Other dental abnormalities are also possible.
What is odontogenic myxoma?
Odontogenic myxoma is a rare intraosseous neoplasm, which is benign but locally aggressive. It rarely appears in any bone other than the jaws. It is considered to be derived from the mesenchymal portion of the tooth germ.
What causes Cementoma?
The cause of the cementoma continues to be unknown and is linked with many sources, including trauma, nutritional deficiency, metabolic disturbances, constitutional factors, and others. Zegarelli and Kutscherl’ have collected data which suggest an association with an endocrine disturbance of an unknown nature.
What causes Cemento osseous dysplasia?
Cemento-osseous dysplasia (COD) is a benign condition of the jaws that may arise from the fibroblasts of the periodontal ligaments. It is most common in African-American females.
What is Cemental dysplasia?
Periapical cemental dysplasia is a benign condition mostly seen in patients over 20 years of age and is more common in women. The lesion occurs in and near the periodontal ligament around the apex of a tooth, usually a mandibular incisior.
What are the two types of cementum?
Cementum is classified into two types:Cellular cementum – Present at the apex of the root, this cementum contains cells called cementocytes.Acellular cementum (not containing cells) – This cemetum does not contain cells and covers the upper half or third of the root towards the crown.
What is a Cementoma?
Cementoma is an odontogenic tumor of cementum. … Considerable thickening of the cementum can often be observed. A periapical form is also recognized. Cementoma is not exclusive to the mandible as it can infrequently occur in other parts of the body such as the long bones.
How common is odontogenic Keratocyst?
An odontogenic keratocyst is a rare and benign but locally aggressive developmental cyst. It most often affects the posterior mandible and most commonly presents in the third decade of life. Odontogenic keratocysts make up around 19% of jaw cysts.
What is odontogenic Keratocyst?
The odontogenic keratocyst (OKC) is a cystic lesion of odontogenic origin, which is classified as a developmental cyst derived from the dental lamina. This lesion was first described in 1956 by Phillipsen. It is one of the most aggressive odontogenic cysts of the oral cavity.
What is florid Cemento osseous dysplasia?
Florid cemento-osseous dysplasia (FCOD) is a condition that occurs in the jaw bone, especially close to where the teeth are formed. People with FCOD develop lesions in the jaw, were spots of normal bone are replaced with a mix of connective tissue and abnormal bone.
What is a myxoma tumor?
An atrial myxoma is a noncancerous tumor in the upper left or right side of the heart. It most often grows on the wall that separates the two sides of the heart. This wall is called the atrial septum.
