Odontome composé: à propos d'un cas clinique

Les odontomes sont des tumeurs bénignes des maxillaires composées de dérivés de l'épithélium odontogène et de l'ectomésenchyme. Ils sont divisés en deux groupes: odontome composé et odontome complexe. L'odontome composé est constitué de nombreuses dents rudimentaires, de très petite taille, groupées dans un sac dont la paroi conjonctive est identique à celle du follicule dentaire normal. Il s'agit d'une jeune patiente qui s'est présentée à la consultation pour une tuméfaction maxillaire antérieure évoluant depuis 4 ans. La patiente a rapporté qu'elle a subi un traumatisme à l'enfance. L'évolution de la tuméfaction était asymptomatique. L'examen exobuccal était sans spécificité. L'examen endobuccal a montré la présence au niveau de la muqueuse vestibulaire du maxillaire antérieur, d'une tuméfaction dure à la palpation et indolore. La muqueuse de recouvrement était d'aspect normal. La TDM a montré des images radiopaques entourées d'un halo radioclaire au niveau du secteur maxillaire antérieur droit autour de la racine de la 11, avec une rupture de la corticale externe et sans envahissement des fosses nasales. Les données cliniques et radiologiques ont orienté vers un odontome composé. Une exérèse chirurgicale des odontomes a été réalisée. L'odontome fait partie des tumeurs odontogéniques benignes épithélio-mésenchymateuses mixtes. L'étiologie de l'odontome est inconnue. Il peut apparaître suite à un ancien traumatisme. Les odontomes composés sont asymptomatiques et découverts au cours d'un examen radiographique de routine. Le traitement consiste à l'extraction chirurgicale de l'odontome seule ou suivi d'un traitement orthodontique en cas d'inclusion d'une dent

Odontomas are benign jaw tumors composed of derivatives of odontogenic epithelium and ectomesenchyme. They are divided into two groups: compound odontoma and complex odontoma. A compound odontoma is made up of many rudimentary teeth, very small, grouped in a sac whose connective wall is identical to that of the normal tooth follicle. A young patient presented for the consultation for an anterior maxillary swelling that has progressed for 4 years. The patient reported that she suffered trauma as a child. The progression of the swelling was asymptomatic. The extra oral examination was unspecific. Intraoral examination showed the presence in the vestibular mucosa of the anterior maxilla, a swelling that was hard on palpation and painless. The covering mucosa was normal in appearance. CT showed radiopaque images surrounded by a radiolucent halo in the right anterior maxillary sector around the root of 11, with a rupture of the external cortex and without invasion of the nasal cavity. Clinical and radiological data have pointed to a compound odontoma. Surgical removal of the odontomas was performed. Odontoma is one of the benign mixed epithelial-mesenchymal odontogenic tumors. The etiology of odontoma is unknown. It can appear following an old trauma. Compound odontomas are asymptomatic and discovered during routine radiographic examination. Treatment consists of surgical extraction of the odontoma alone or followed by orthodontic treatment in the event of inclusion of a tooth.

Multiple Dens Evaginatus- A Rare Case Report With A Review Of Literature

Densevaginatus (DE) is a developmental disturbance affecting the shape of the teeth which is characterized by the presence of accessory enamel projections along with dentin and pulpal core on the occlusal or lingual surface of the teeth. It affects both the primary and permanent dentition. The clinical intendment is focused on early pulpal exposure due to occlusal trauma, fracture or attrition leading to infection. Treatment may be conservative or interventional. The occurrence of DE either isolated or conjoined with other dental anomalies has been reported. This article presents with a case report of conjoined occurrence of multiple DE (Schulge type 5) along with partial anodontia of maxillary premolars and left molars and also reviews the etiology, classification, diagnosis and management strategies of the teeth with DE.

Extragnathic and gnathic odontome.

This is a very rare case report of a multiple odontome involving the upper jaws, lower jaws and an extragnathic site. A thirty seven year‑old male complained of missing teeth in his left upper and lower jaw since childhood. Radiographic examination revealed multiple calcified teeth like structures in the left side of the patient’s maxilla, mandible and mastoid region of skull base. We arrived at the diagnosis of compound odontome. Patient was otherwise systemically normal and with good health. He underwent surgical enucleation of the jaw odontome while the extragnathic odontome was left under observation. This rare case report proves that the embryonic dental cells might migrate to the primordium of the Rathke’s pouch and further might be carried towards the site of the developing cranial base region.

A Ghost in a Host! – An Odontome with Unusual Presentation.

Odontomas are hamartomas, being of two types: Compound and complex and are nonaggressive hamartomatous developmental malformations or tumors of odontogenic origin, which consists of enamel, dentin, cementum and pulpal tissue. They are usually asymptomatic and diagnosed on routine radiological studies in the second and third decades of life. Compound variety is more often found in anterior maxilla; complex occurs in molar areas of either jaw. Mean age of occurrence is 12-16 years. Radiographically, they present as radiopacities surrounded by a radiolucent rim in complex variety and tooth like structures of different size and shape surrounded by radiolucency in compound variety. Here, we have discussed a rare case of erupting complex odontoma associated with an impacted mandibular third molar.

Compound Odontome Associated With Impacted Mandibular Canine.

Odontomas are considered to be hamartomas rather than a true neoplasm. They consist chiefly of enamel and dentin, with variable amount of pulp and cementum when fully developed. They are generally asymptomatic and are included under the benign calcified odontogenic tumors. Here is a case presentation of compound odontome with impacted permanent teeth in anterior mandible in a 21year old boy, which not a usual site for compound odontomes. Radiograph revealed a calcified mass and the case was finally diagnosed to be compound odontome. The mass was surgically excised and follow up for one year showed no recurrence.

ODONTOMA (complex composite odontome).

An odontomas are malformations of the dental tissues and may interfere with the eruption of associated tooth, which are benign, slow growing and non-aggressive. These lesions are usually asymptomatic and often diagnosed during routine radiography in the second decade of life. Aim is to present a case of complex odontoma associated with an impacted supernumerary tooth in anterior maxillary region and a thorough review on the etiopathogenesis, clinical presentation, radiological findings, histopathological features and treatment aspects of odontomas.

Erupted compound odontome associated with impactedmaxillary second premolar: a case report / Odontoma composto erupcionado associado a segundopré-molar superior impactado: um relato de caso

Introduction: Odontomas are the most common odontogenic tumour. They are considered to be hamartomasrather than neoplasms. They are generally asymptomatic and are discovered on routine radiographicexamination. Odontomas might be associated with disturbance in tooth eruption. Other symptoms includeretention of deciduous teeth, pain, swelling, expansion of cortical bone, tooth displacement. Eruption ofodontoma in the oral cavity is rare with only 11 cases being reported about erupted compound odontomas.Case report: An unusual case of erupted compound odontome associated with pain and impacted maxillaryleft second premolar is reported. We have also discussed the clinical, radiographic and histopathologicfeatures of this rare condition.

Introdução: Odontomas são os mais comuns entre os tumores odontogênicos. Eles são considerados hamartomas,ao invés de neoplasias. Eles geralmente são assintomáticos e descobertos em exames radiográficos derotina. Odontomas podem estar associados com distúrbio na erupção dentária. Outros sintomas incluem retençãode dentes decíduos, dor, inchaço, expansão do osso cortical e deslocamento do dente. A erupção de um odontoma na cavidade oral é rara, com apenas 11 casos relatados de odontomas compostos erupcionados.Relato de caso: Um caso incomum de odontoma composto associado à dor e segundo pré-molar superior esquerdoimpactado é relatado neste artigo. Os aspectos clínicos, radiográficos e histopatológicos dessa doençarara também são discutidos.

A Rare Case of Complex Odontome With Dentigerous Cyst Lining In The Anterior Maxilla.

Odontomas and dentigerous cysts are the common findings in the daily practice of dental professionals. However, simultaneous pathologies of odontome and dentigerous cyst are uncommon and diagnosis based on the radiographic appearance of such lesions is a challenge to overcome. They together are potential for complications like attaining large size, root resorption, destruction of jaw bones and some shows neoplastic changes like ameloblastoma. The potential complications justify histopathological evaluation and enucleation of all the odontomes. This paper is to describe a rare case of complex odontome with dentigerous lining in the anterior maxilla.

Multicystic Variant of Calcifying Cystic Odontogenic Tumor Associated With Odontome - Report of A Case And Review.

Calcifying cystic odontogenic tumor is an uncommon odontogenic neoplasm which is included in the heterogenous group of lesions under a broader description of Ghost cell odontogenic tumors. All these lesions have the presence of ghost cells as a common feature. Calcifying cystic odontogenic tumor is a unique lesion with variable biologic behaviour and found to occur with other odontogenic tumours. We present a case of Calcifying cystic odontogenic tumor occurring in a 15 year old boy involving an unerupted permanent canine and premolar. The tumor was multicystic in nature and was associated with a complex odontome. This article also includes an update on nomenclature and classification of ghost cell odontogenic lesions.
