Simultaneous occurrence of compound odontoma and arrested root formation as developmental disturbances after maxillofacial trauma: a case report.

2009

Traumatic injury to a primary tooth and/or a bone fracture has the potential to damage the underlying permanent tooth germ which may disturb its development. The extent of the malformation depends on the developmental stage of the permanent tooth and the intensity of the trauma. The presence of infection may be a predictive factor for these abnormalities. Open surgical procedures can also potentially cause impaction and developmental disturbances. Several developmental alterations such as discolouration, hypoplasia, crown dilaceration, root angulation or dilaceration, sequestration of permanent tooth buds and disturbance in eruption have been reported in permanent teeth after trauma. Howeve…

Peripheral developing odontoma in newborn. Report of two cases and literature review.

2008

Extra-osseous odontogenic tumors are rarely observed. However, it is widely accepted that the remains of odontogenic epithelium entrapped in the oral soft tissues may be a possible source for peripheral odontogenic tumors differentiation. Peripheral developing odontoma is considered exceptionally rare, since few similar cases are described in the English-related literature under diverse nomenclature, such as irregular eruption, ectopic tooth, ectopic soft-tissue mesiodens, ectopic odontoma and extra-osseous tooth germ. Previously reported cases invariably affected children and surgical exploration revealed tooth germs exclusively embedded in the soft tissue without bone involvement. Microsc…

Ameloblastic fibro-odontoma: A conservative surgical approach

2009

Ameloblastic fibro-odontoma (AFO) is a rare benign mixed odontogenic tumor that occurs predominantly in children and young adults with no gender predilection and anatomic site, usually appearing as a painless swelling. We present a case of an 11-year-old non-Caucasian boy complaining of large painless isolated swelling in the right mandibular body. Intraoral examination revealed a tumoral mass with cortical bone expansion, covered by normal mucosa measuring 4.0 x 2.0 cm, located on both the lingual and buccal surfaces of the right body of the mandible, with displacement of the neighboring teeth. Panoramic radiography revealed an expansile, radiolucent and well circumscribed lesion with scat…

Association between odontoma size, age and gender: Multivariate analysis of retrospective data

2019

Background The variety of characteristics related to odontoma research, including an unexplored one such as size, merits a multivariate approach that allows the adequate drawing of inferences with pertinent conclusions. The objective of this study is to establish the possible association between some characteristics related to the odontoma, tumor size among them. Material and methods The sociodemographic characteristics of 60 patients were evaluated. Diagnosis, size, location, type of treatment performed, and prognosis were determined. These data were analyzed descriptively and through multivariate models. Results Thirty-four compound and 26 complex odontomas in 32 men and 28 women were obs…

Odontoameloblastoma: descripción de un caso y revisión de la literatura

2004

El odontoameloblastoma (OA) es un tumor odontogénico mixto extremadamente raro que aparece en los huesos maxilares y que presenta tanto componentes epiteliales como mesenquimales. El término odontoameloblastoma fue incluido en la clasificación de 1971 de la OMS. Tan solo 23 casos bien documentados han sido publicados. Debido a su rareza, existe controversia en cuanto al tratamiento de este tumor. Presentamos un nuevo caso de OA que afecta a la mandíbula y simula un odontoma compuesto, así como una breve revisión de la literatura. Odontoameloblastoma (OA) is an extremely rare mixed odontogenic tumor appearing within the maxillary bone, with both epithelial and mesenchymal components. The ter…

Odontogenic tumours: A review of 266 cases.

2012

Objectives: The aim of this study was to examine the relative frequency of odontogenic tumours at a tertiary hospital in Ibadan, as well as to study the various histologic types based on WHO 2005 classification and to compare results from this study with those of previous studies. Study design: The records of the Oral Pathology Department of University College Hospital were reviewed. Lesions diagnosed as odontogenic tumours were categorized into four groups based on WHO 2005 classification and were analyzed for age, sex and site using SPSS for Window (version 18.0; SPSS Inc. Chicago, IL) and frequency tables were generated. Results: Two hundred and sixty six (41.7%) cases of odontogenic tum…

Prevalence of dental anomalies in Indian population

2013

Objectives: Developmental anomalies of the dentition are not infrequently observed by the dental practitioner. The aim of the present study was to determine the prevalence of dental anomalies in the Indian population. Study design: A retrospective study of 4133 panoramic radiographs of patients, who attended the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 was done. The ages of the patients ranged from 13 to 38 years with a mean age of 21.8 years. The orthopantomographs (OPGs) and dental records were examined for any unusual finding such as congenitally missing teeth, impactions, ectopic eruption, supernumerary te…
