Compound odontomas are regularly calcified tissue that bear similarity to teeth or appear as a collection of small teeth. We report a rare case of compound odontoma in the mandible of an adult patient with clinical and radiological features and a review of the literature.
What is the difference between compound and complex odontoma?
There are two types of odontomas: complex and compound. A compound odontoma has a tooth-like structure and is arranged in a uniform manner, similar to a normal tooth, while a complex odontoma has a mixed structure of disorganized tissue mass, according to the WIMJ article.
Are odontomas benign?
While an odontoma is a tumor, it’s a benign one and not uncommon. That alone is great news! However, odontomas usually require surgical removal. They’re made up of dental tissue that resembles abnormal teeth or calcified mass that invade the jaw around your teeth and could affect how your teeth develop.
What causes compound composite Odontoma?
It has been associated with various pathological conditions, like local trauma, inflammatory and/or infectious processes, mature ameloblasts, cell rests of serres (dental lamina remnants) or hereditary anomalies (Gardner’s syndrome and Hermann’s syndrome), odontoblastic hyperactivity, and alterations in the genetic …
What is AOT in dentistry?
Abstract. Adenomatoid odontogenic tumor (AOT) is a well-recognised slow growing benign tumor derived from complex system of dental lamina or its remnants. This lesion is categorised into three variants of which the more common variant is follicular type which is often mistaken for dentigerous cyst.
What is an Ameloblastoma?
Overview. Ameloblastoma is a rare, noncancerous (benign) tumor that develops most often in the jaw near the molars. Ameloblastoma begins in the cells that form the protective enamel lining on your teeth. Ameloblastoma occurs in men more often than it occurs in women.
What is a complex Odontoma?
Complex odontoma is a common odontogenic tumor, and it is usually a hard painless mass, which rarely exceeds diameter of the tooth. Most of these lesions are discovered accidentally on radiographic examination. The common signs and symptoms include impacted permanent teeth and swelling.
How rare is an Odontoma?
Odontomas constitute about 22% of all odontogenic tumors of the jaws. Approximately, 10% of all odontogenic tumors of the jaws are compound odontomas. The incidence of compound odontome ranges between 9 and 37% and the complex odontome is between 5 and 30%.
What is dens in dente?
Dens in dente is a rare developmental tooth anomaly characterized by invagination of the enamel organ into the dental papilla that begins at the crown and often extends to the root even before the calcification of the dental tissues.
Are Odontomas genetic?
Odontoma dysphagia syndrome (Bader syndrome) is a rare syndrome (<10 cases reported to date) first described in 1967. The cause is not known but it is suspected to be genetic in origin.
Can you leave an odontoma?
Most common treatment is surgical enucleation due to well-encapsulated nature of odontomas allowing separation from surrounding bone. If left untreated can result in a dentigerous cyst.
Does odontoma cause pain?
Odontomas rarely erupt into the mouth and tend to be associated with impacted teeth. Despite their benign nature, however, their eruption into the oral cavity can give rise to pain, inflammation, and infection and different clinical appearance.
What does an Odontoma look like?
The complex odontoma appears as an irregular mass of calcified material surrounded by a thin radiolucent area with smooth periphery and the compound type shows calcified structures resembling teeth in the center of a well-defined radiolucent lesion.
What is Ameloblastic fibroma?
Ameloblastic fibroma (AF) is an extremely rare true mixed benign tumor that can occur either in the mandible or maxilla.[1] It is frequently found in the posterior region of the mandible, often associated with an unerupted tooth.[2] It usually occurs in the first two decades of life with a slight female predilection, …
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.
How can you tell the difference between AOT and Dentigerous cysts?
The characteristic radiographic difference between dentigerous cyst and follicular AOT is that the radiolucency in the former is never associated with part of the root (always attached at the cervix) whereas in the latter it is most commonly associated with the part of the root.
What causes periapical cyst?
Periapical cysts result from infection of the tooth, which spreads to the apex and into the adjacent bone. This leads to apical periodontitis, granuloma formation and eventual cyst formation. These cysts are therefore centered on the apex of the tooth and tend to be small, most <1 cm.
What is Gorlin cyst?
The calcifying cystic odontogenic tumor (CCOT), also known as calcifying odontogenic cyst (COC) or Gorlin cyst is a rare developmental lesion which arises from odontogenic epithelium. Although the lesion has been commonly recognized as a benign odontogenic cyst since Gorlin et al.
Is ameloblastoma life threatening?
A review of the medical literature provides further evidence of the locally aggressive behavior and potentially lethal nature of this tumor. No effective treatment has evolved for extensive ameloblastomas of the maxilla that have invaded surrounding vital structures.
Can ameloblastoma be cancerous?
Although it is uncommon, ameloblastomas have been known to become malignant and spread to other parts of the body, especially to the lungs. The initial surgical treatment must be carefully and scrupulously done to avoid recurrence. Ameloblastomas do not usually become malignant.
How do I get rid of ameloblastoma?
Ameloblastoma treatment usually includes surgery to remove the tumor. Ameloblastoma often grows into the nearby jawbone, so surgeons may need to remove the affected part of the jawbone. An aggressive approach to surgery reduces the risk that ameloblastoma will come back. Surgery to repair the jaw.
Is an Odontoma cancerous?
Odontomas are one of the most common odontogenic tumors, constituting approximately 20 percent of odontogenic tumors. Ameloblastoma is the most common with 39.6 percent of odontogenic tumors. Odontomas are not cancer. They are considered benign tumors, though in humans they are often surgically removed.
How is Odontoma treated?
Odontoma is the most common odontogenic benign tumor, and the treatment of choice is generally surgical removal. After excision, bone grafts may be necessary depending on the need for further treatment, or the size and location of the odontoma.
What are odontogenic tumors?
Odontogenic tumors are a group of neoplastic growths that originate from the tissues responsible for tooth formation and the periodontal apparatus of the jaw. Odontogenic tumors usually present as radiolucent defect, which makes diagnosis somewhat confusing while differentiating them from cysts.
How is Odontoma formed?
Odontoma is a benign tumor originating from an alteration of differentiated mesenchymal and epithelial odontogenic cells; it has the capacity of forming enamel, dentin and cement. They are classified into compound and complex, in a 2:1 relationship, the difference between both being dental tissue organization.
What is cause Hypercementosis?
Hypercementosis is excessive deposition of cementum on the tooth roots. In most cases, its cause is unknown. Occasionally, it appears on a supraerupted tooth after the loss of an opposing tooth. Another cause of hypercementosis is inflammation, usually resulting from rarefying or sclerosing osteitis.
Is dentin vascular or avascular?
In contrast with bone, dentin is not vascularized, except in some fish teeth where the existence of vasodentin is well-documented [4].
What are ghost teeth?
Teeth in a region or quadrant of maxilla or mandible are affected to the extent that they exhibit short roots, wide open apical foramen and large pulp chamber, the thinness and poor mineralisation qualities of th enamel and dentine layers have given rise to a faint radiolucent image, hence the term Ghost teeth.
What is a tooth within a tooth called?
INTRODUCTION. ‘Dens in dente’ meaning ‘tooth within a tooth’ is a rare developmental anomaly of the tooth affecting mostly the permanent maxillary lateral incisors and less commonly the other permanent teeth and the primary dentition. It is also called as ‘dens invaginatus’ or ‘dilated composite odontome’.
What is a tooth inside a tooth called?
Pulp. Pulp is the innermost portion of the tooth. It’s made of tiny blood vessels and nerve tissue. Pulp cavity. The pulp cavity, sometimes called the pulp chamber, is the space inside the crown that contains the pulp.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
