Management of compound odontoma with 70 denticles and impacted lateral incisor over an 8-year follow-up

Odontomas are benign developmental tumors formed by the improper growth of completely differentiated epithelial and mesenchymal cells of odontogenic origin. The etiology of odontoma is unknown and it is detected during routine radiographic examination. The ideal management is early detection and surgical enucleation. The commonly associated clinical problems of odontomas are delayed exfoliation of primary teeth, delayed eruption or impaction of permanent teeth, displacement of teeth, root resorption, congenital missing, and widening of follicular space. Here, we describe a unique case of compound odontoma with a high number of denticles managed based on a definite decision support system over 8 years. An 8-year-old boy with 70 denticles in the left maxillary region underwent enucleation. On periodic follow-up, the associated impacted lateral incisor was extruded orthodontically.

Los odontomas y sus implicancias / Odontomas and their implications

La Organización Mundial de la Salud clasifica los odontomas como tumores odontogénicos benignos compuestos de epitelio odontogénico y ectomesénquima odontogénico con formación de tejido duro dental. Los odontomas, por definición, son lesiones habitualmente hamartomatosas que suelen encontrarse sobre dientes no erupcionados, compuestas de esmalte, dentina, pulpa y cemento en formas reconocibles de dientes (odontoma compuesto) o bien como una masa nudosa sólida (odontoma complejo). Algunos tumores constituyen una combinación de ambos tipos (es decir, no solo contienen estructuras múltiples de aspecto similar a un diente, sino también masas calcificadas de tejido dental dispuestas al azar). Estas lesiones se denominan odontomas complejos-compuestos. Otro tipo, el fibroodontoma ameloblástico, es un tumor infrecuente que contiene los componentes tisulares blandos del fibroma ameloblástico y los componentes de tejido duro del odontoma complejo (AU)

The World Health Organization classifies odontomas as a benign odontogenic tumor composed of odontogenic epithelium and odontogenic ectomesenchyma with dental hard tissue formation. Odontomas, by definition, are usually hamartomatous lesions, frequently found on unerupted teeth, composed of enamel, dentin, pulp and cement in recognizable forms of teeth (compound) or a solid knotty mass (complex). Some tumors constitute a combination of both types (i.e., they not only contain multiple structures similar in appearance to a tooth, but also calcified masses of dental tissue arranged at random). These lesions are called complex-compound odontomas. Another type, the ameloblastic fibro-odontoma, is an infrequent tumor that contains the soft tissue components of the ameloblastic fibroma and the hard tissue components of the complex odontoma (AU)

Transmigrated canines associated to odontomas / Caninos transmigrados asociados a odontomas

We present the case of a 13-year-old patient with bilateral transmigration of mandibular canine associated with multiple composite odontoma. Impacted canines are very uncommon, with a 0.1 % to 3.6 % prevalence of appearance. The presence in the mandible is less frequent. The odontoma development is often associated with the impacted canines. The etiology is unknown but is associated with traumatic, infectious, hereditary or genetic factors. This pathology is asymptomatic and associated with eruption disorders in temporal and permanent dentition.

Presentamos el caso de un paciente de 13 años de edad con trasmigración bilateral de canino mandibular asociado a múltiples odontomas compuestos. Los caninos impactados son muy poco frecuentes, con una prevalencia de aparición de 0,1 % a 3,6 %. La presencia en la mandíbula es menos frecuente. El desarrollo de odontomas se asocia a menudo con los caninos impactados. La etiología es desconocida pero está asociada con factores traumáticos, infecciosos, hereditarios o genéticos. Esta patología es asintomática y está asociada a trastornos de erupción en dentición temporal y permanente.

Diagnóstico precoz y tratamiento oportuno del odontoma compuesto en un niño Peruano de 3 años / Early diagnosis and timely treatment of composite odontoma in a peruvian child of 3 years

Los odontomas son los tumores odontogénicos benignos y asintomáticos más comunes en los maxilares. Generalmenteel diagnóstico y tratamiento ocurren entre la segunda y tercera década de la vida. El propósito del caso que presentamo sexplica que el diagnóstico precoz se puede obtener desde los primeros años de vida con la interpretación de los antecedentes anamnésicos, la evaluación clínica y radiográfica oportuna para realizar el tratamiento temprano de los odontomas, con el objetivo de evitar en los pacientes complicaciones y secuelas a futuro como la retención dentaria, reabsorción o dilaceración radicular, expansión ósea, formación quística y sus recurrencias.

Odontomas are the most common benign and asymptomatic benign tumor in the maxillaries. Diagnostic and treatment generally occur from the second decade of life. The purpose of the case presented explains the historical background,timely clinical and radiographic evaluation allow to obtain early diagnostics and therefore realize early treatment of odontomas, with the objetive to avoid future complications and aftermaths in patients as dental retention, root reabsorptionand dilacerations, bone expansion, cyst formation and recurrence.

Odontoma erupcionado: presentación de un caso y revisión de la literatura / Erupted odontoma: a case report and literature review

Los odontomas son clasificados por la OMS como tumores odontogénicos benignos compuestos por esmalte, dentina, cemento y pulpa, considerados lesiones hamartomatosas más que verdaderos neoplasmas. En casos excepcionales erupcionan hacia la cavidad bucal.En este trabajo se realiza la presentación de un caso de odontoma que se expone espontáneamente a la cavidad bucal, en un paciente masculino de 22 años, entidad que se conoce con el nombre de “odontoma erupcionado”. Se presenta también una revisión de la literatura entre los años 1980 y 2015, de los casos existentes de esta patología.

Odontomas are classified by the WHO as odontogenic tumors composed of enamel, dentin, cement and pulp, considered hamartomatous lesions rather than true neoplasms. In exceptional cases, odontomas erupt into the oral cavity.This study reports a case of odontoma spontaneously exposed to the oral cavity, which is known as “erupted odontoma”, in a 22-year-old male patient. A review of the literature between 1980 and 2015 of the existing cases of this pathology is also presented.

Unusual Form of Complex Odontome: A Case Report.

Odontomas are the most characteristic among odontogenic tumors of the jaws, which are benign, slow-growing and non-aggressive. There are various theories, or etiological factors were quoted for occurrences of odontomas. Being asymptomatic in nature sometimes it may interfere with the eruption of the associated tooth leading to impaction or delayed eruption. Most of the lesions are diagnosed accidently on routine radiological examination in the second and third decades of the life. The sole management mainly depends on the early diagnosis, histopathological examination and surgical removal of the lesion. Here, we were presenting an interesting case of unusually large complex odontoma associated with pain, as well as missing molar is reported.

To research the clinical and paraclinical characteristic of odontomas

All cases of odontoma treated at Hanoi Institute of Odonto-maxillo facial Institute from 1994 to 2004 were investigated. Odontoma had been occurred at any age group, the lowest was 6, the highest was 67 and mean age 20.59 years. 58.82% of Odontoma had been occurred in the upper maxial bone, 41.18% in the lower. Common clinical sumptoms were bone swell in 88.24% of cases, permanent loss of tooth 47.06%, existing milk tooth in 76.47%, pain in 11.76%. In 47.06% the pre-operative diagnosis was agreed with patho-anatomical diagnosis and 93.33% of preoperative diagnosis with pathoanatomical diagnosis Odontoma complex accounted for 73.33% and odontoma compound 26.67%.
