Panoramic x-ray is indicated, with a radiolucent image with numerous radio opaque formations that resemble dental structures and a radiolucent band in its periphery presumptively diagnosed as a compound odontoma. It is referred to the second level of attention for excresis and definitive diagnosis. Some characteristics of its etiology, diagnosis and treatment were discussed(AU)

Association Between Odontoma and Impacted Teeth.

Odontoma is considered to be the most common odontogenic tumor of the oral cavity. Most odontomas are asymptomatic and are discovered during routine radiographic investigations and can cause disturbances in the eruption of the teeth, most commonly delayed eruption or deflection. By a retrospective study design, demographic and clinical data regarding patients who presented odontomas from year 1995 to 2015 were obtained in order and the influence of active therapy on the dentition and on the treatment of impacted teeth was analyzed. Forty-five patients (mean age 14.2 years) with 29 complex and 16 compound odontomas were included in this retrospective study. Initial symptoms were delayed eruption of permanent teeth (n = 25), pain (n = 6), swellings (n = 4), and no symptoms (n = 10); 31 patients were discovered by incidence, all of them via panoramic radiographs. The mandible/maxilla ratio was about 2:1 (31/15). Thirty-two out of 45 odontomas were in close proximity of at least 1 tooth (n = 21 at incisive). A total of 12 teeth were extracted (complex: n = 8; compound: n = 4). Of the nonextracted teeth, 33 teeth were displaced and retained. Of those, 29 teeth were aligned through orthodontic-surgical approach and 4 teeth erupted spontaneously after surgery during the follow-up period. An early detection of odontoma is more likely an accidental radiological finding, hence the need for routine radiographic analysis should be emphasized. Early diagnosis of odontomas in primary dentition is crucial in order to prevent later complications, such as impaction or failure of eruption of teeth.

Odontoma compuesto: revisión de la literatura y reporte de un caso con 40 dentículos / Compound odontoma: a review of the literature and report of a case involving 40 denticles

El odontoma compuesto es un tumor benigno odontogénico conformadopor varios dentículos o dientes rudimentarios los cuales se encuentran conformados de tejido dental organizado. Su etiología no está biendefi nida pero se atribuye a traumatismos durante la primera dentición, así como a procesos infl amatorios o infecciosos, anomalías hereditarias o alteraciones en el gen de control del desarrollo dentario. Su presencia se encuentra entre los tres tumores odontogénicos más frecuentes, en diferente orden según el autor que se consulte. Está relacionado por logeneral con una alteración en la erupción o malposición dental. Tiene predilección en hueso maxilar, frecuentemente asintomáticos, se caracterizan por un crecimiento lento, diagnosticándose de forma casualmediante exámenes radiográfi cos de rutina entre la segunda y terceradécada de la vida. En este estudio se presenta el caso de un pacientefemenino de 14 años de edad, con presencia de un odontoma compuestode 40 dentículos, en la región parasinfi siaria izquierda, tratado medianteenucleación, y colocación de injerto óseo.

The compound odontoma is a benign odontogenic tumor composed ofseveral denticles or rudimentary teeth made up of organized dentaltissue. Its etiology is not well defi ned but is attributed to trauma duringthe fi rst dentition, as well as to infl ammatory or infectious processes, inherited abnormalities, odontoblastic hyperactivity or alterations in the gene that controls tooth development. It is among the 3 mostcommon odontogenic tumors, though its ranking among these varies depending on the author consulted. It is usually associated with analteration in the eruption or malposition of teeth. It has a predilection for the maxillary bone, and is often slow-growing and asymptomatic. Odontomas are diagnosed incidentally during routine X-ray examinations of patients between the second and third decades of life. In this study, we present the case of a 14-year-old female patient with the presence of a compound odontoma comprised of 40 denticles inthe left parasymphyseal region, which is treated by enucleation andbone graft placement.

Elodontoma in Two Guinea Pigs.

Elodontoma was diagnosed in two pet guinea pigs, one involving a maxillary premolar tooth and the other affecting a mandibular incisor tooth. Diagnostic imaging, including radiographs, computed tomography, and oral endoscopy was performed in order to quantify dental disease. Diagnostic imaging was also used to guide treatment of acquired dental disease, which included intraoral restoration of normal occlusal plane and tooth extraction using an extraoral approach. These are the first histologically confirmed cases of elodontoma in guinea pigs.

Odontomas and supernumerary teeth: is there a common origin?

The aim of the present work is to analyze all scientific evidence to verify whether similarities supporting a unified explanation for odontomas and supernumerary teeth exist. A literature search was first conducted for epidemiologic studies indexed by PubMed, to verify their worldwide incidence. The analysis of the literature data shows some interesting similarities between odontomas and supernumerary teeth concerning their topographic distribution and pathologic manifestations. There is also some indication of common genetic and immuno-histochemical factors. Although from a nosological point of view, odontomas and supernumeraries are classified as distinct entities, they seem to be the expression of the same pathologic process, either malformative or hamartomatous.

An idiosyncratic post-traumatic tetrad: compound odontome, dentigerous cyst, impaction, and double-dilaceration.

OBJECTIVE: This report describes the case of a 13-year-old patient who experienced traumatic intrusion of the primary maxillary right central incisor and subsequently suffered an atypical tetrad, comprising of an unerupted compound odontoma associated with a dentigerous cyst, and an impacted, doubly dilacerated permanent maxillary right central incisor; however, the high interconnectivity of the occurrence of four pathologies together is unusual has not previously been reported. SUMMARY: The pathologies were detected 7 years after trauma; surgical removal of odontome along with the dentigerous cyst was performed, followed by orthodontic extrusion of the impacted double-dilacerated permanent central incisor. The 18-month follow-up shows no pathology, no gingival recession, and normal probing depth.

Odontoma compuesto: casos clínicos y revisión de la literatura / Compound odontoma: case reports and review of the literature

Objetivo: el objetivo de este trabajo es describir los odontomas compuestos desde una perspectiva actual, a partir de casos clínicos. Casos clínicos: se presentan cuatro casos de niños a los que se les realizó la enucleación de un odontoma, cuyas biopsias confirmaron el diagnóstico inicial.

Management of multiple sequelaes in permanent dentition: 3 years follow-up.

A 12-year-old patient with multiple sequelaes of permanent dentition due to trauma in primary dentition at the age of 8 months, is presented. Clinical and radiographical examinations revealed aesthetical defects, crown-root malformations (#21), hypoplasia (#12, #22), tooth transposition (#13) and odontoma-like malformation (#11). The performed conservative, endo-surgical and prosthetic treatment to gain back the aesthetic and function is reported.

Developmental dental alterations in permanent teeth after intrusion of the predecessors: clinical and microscopic evaluation.

This case report describes the management of developmental dental alterations in permanent dentition as a consequence of severe intrusive luxation in its predecessors in a child of 2 years. At 10 years of age, this patient was referred for consultation due to lack of permanent maxillary right central and lateral incisors. Radiographic examination revealed impaction of hypoplasic permanent maxillary central incisor, absence of the lateral incisor and compound odontoma in region of the permanent maxillary lateral incisor. The odontoma was surgically removed and unerupted central incisor was placed in orthodontic traction over a period of 8 months. The central incisor presented with abnormal shape and was restored with composite resin. Odontoma histologic analysis was carried out through Hematoxylin and Eosin coloration and Scanning Electron Microscopy. Cement and osteocement formations were found in soft tissue, as well as some irregularly distributed dentine islands of tooth-like structures, indicative of compound odontoma. We followed up this patient for 5 years and orthodontic management was successfully performed for correct alignment of the maxillary right central incisor impacted by compound odontoma.

Simultaneous occurence of compound odontoma and arrested root formationas developmental disturbances after maxillofacial trauma: A case report

Traumatic injury to a primary tooth and/or a bone fracture has the potential to damage the underlying permanenttooth germ which may disturb its development. The extent of the malformation depends on the developmentalstage of the permanent tooth and the intensity of the trauma. The presence of infection may be a predictive factorfor these abnormalities. Open surgical procedures can also potentially cause impaction and developmental disturbances.Several developmental alterations such as discolouration, hypoplasia, crown dilaceration, root angulationor dilaceration, sequestration of permanent tooth buds and disturbance in eruption have been reported in permanentteeth after trauma. However, odontoma-like malformations and partial or complete arrest of root formationare rare complications developed after trauma. This article presents a rare case with simultaneous occurrence ofan odontoma-like malformation and complete and partial arrested root formations as the results of maxillofacialtrauma. Almost all pediatric fractures must be managed with closed reduction as much as possible. However, if itis necessary to perform an open reduction, careful attention must be paid during placement of the osteosyntheticplates and screws; and tooth bud development must be followed periodically (AU)

Bilateral complex odontomas: a rare complication of external mandibular distraction in the neonate.

BACKGROUND: The authors present an unusual complication of external mandibular distraction in a child with bilateral complex odontomas in the posterior mandible. CLINICAL REPORT: The patient is a 4-year-old girl with a history of micrognathia, glossoptosis, and respiratory distress (Pierre-Robin sequence) treated with neonatal external mandibular distraction. She was referred to our service with bilateral amorphic radio-opaque masses in the body of the mandible. CONCLUSIONS: The etiology of odontomas is uncertain, but different theories exist, such as local trauma, infection, family history, or spontaneous genetic mutation. After severe intrusion injuries to primary teeth, odontomalike malformations have been known to occur in the underlying permanent teeth later in life. This case highlights that externally placed distractors carry greater potential for injury to internal structures of the mandible owing to the unpredictability of placement.

A case report of Gardner syndrome with hereditary widespread osteomatous jaw lesions.

Gardner syndrome (GS) is an abnormality of familial adenomatous polyposis accompanied by characteristic jaw lesions. Gardner syndrome intestinal polyps have a 100% risk of undergoing malignant transformation; consequently, early identification and surgical intervention of the disease are important to prolong the life of the patient. We present a case of GS in a 55-year-old woman. Familial adenomatous polyposis, osteomatous jaw and ocular lesions, several dental abnormalities, and an abdominal desmoid tumor are the characteristic features of this case. This case demonstrates the presence of unusual, widespread, hereditary, osteomatous jaw lesions that caused diagnostic confusion with familial gigantiform cementoma.

Oral and maxillofacial manifestations of familial adenomatous polyposis.

Patients with familial adenomatous polyposis (FAP) develop multiple premalignant colorectal adenomas. Untreated, one or more of these polyps will progress to colorectal carcinoma in middle-aged adults. Extra-intestinal manifestations of FAP are frequently observed and this combination has been called Gardner's syndrome. Oral and maxillofacial symptoms of FAP include an increased risk of jaw osteomas, odontomas and supernumerary or unerupted teeth. Early diagnosis of FAP is crucial and may be life saving. As oral signs usually precede gastrointestinal symptoms, the dentist may play an important role in the diagnosis of FAP.

Odontoma-like malformation in a permanent maxillary central incisor subsequent to trauma to the incisor predecessor.

This report describes a case of a patient (1 year and 8 months old) with traumatic avulsion of the maxillary right primary central incisor and morphological changes in the germ of the permanent successor. One year after the trauma, an odontoma-like malformation developed. This malformation was removed 6 years after trauma and orthodontic treatment was started. Clinical follow-up and periodic radiographs are necessary after traumatic avulsion of primary teeth to monitor possible sequelae in the permanent successor. An odontoma-like malformation requires a multidisciplinary approach.
