REMOVAL OF LARGE COMPLEX ODONTOMA- CLOSURE OF DEFECT WITH BUCCAL PAD OF FAT

odontomas are mixed benign odontogenic tumors because of their origin from epithelial and mesenchymal cells. Complex odontomas involve more pathological changes than compound odontomas. Odontomas are commonly treated by conservative surgical approach and have less probability of recurrence. During Surgical treatment of large odontomas, a large portion of bone has to be excised. Different Graft options have been discussed in the literature for continuity of this defects. In this case report , an attempt was made to reconstruct a large surgical defect created after surgical excision of a considerably large complex odontome of maxilla by using autografts harvested from the neighbouring buccal area to avoid morbidity of the donor site and the results are satisfactory.

Abstract I. IntroductionOdontomas are the most common types of odontogenictumors, constitutingapproximately 70% of all odonto-genic tumors of the jaws. They are composed of variousformations of dental tissueincluding enamel, dentin, ce-mentum and sometimes pulp 1) . Odontomas are consid-ered to be developmental anomalies resulting from thegrowth of completely differentiated epithelial and mes-enchymal cells that give rise to functional ameloblastand odontoblast 2) .Odontomas are subdivided into compound and complextypes by degrees of morphodifferentiation or similaritieswith normal tooth structures. Compound odontomasconsist of a small malformed tooth having normal enam-el,dentin and cementum. They are usually located in theupper incisor areas and are mostly found in 6~10-year-olds 3) . Complex odontomas consist of a conglomeratemass of less organized dental tissues that seldom showteeth or tooth-like structures compared with compoundodontomas. Complex odontomas are usually located inthe first or second molar areas of the mandible and moreoften occur in males. The lesions constitute about 25%of all odontomas and about 22% of all odontogenic tu-mors of the jaw

Odontoma: Case series & report of cases complicated by infection and multiple denticles

Odontoma is a hamartomatous lesion of odontogenic origin involving both epithelial and mesenchymal tissues. Although it is not an uncommon lesion yet in certain conditions it can lead to complications if left untreated. This is a retrospective review of 30 diagnosed odontoma cases from the archives of Department of Oral & Maxillofacial Surgery, Government Dental College & Hospital, Nagpur, India. Out of these 30 cases, 17 were diagnosed as complex odon toma and 13 cases as compound odontoma. Two of these unusual cases have been described which emphasize the importance of early & appropriate treatment to prevent further morbidity.

Odontoma: a retrospective study of 73 cases

PurposeThe purpose of the present study was to retrospectively evaluate the clinical findings and treatment results for impacted permanent teeth associated with odontomas.Materials and MethodsWe retrospectively investigated 73 odontomas in 72 patients who visited Kyungpook National University Dental Hospital from April 2004 through November 2011. The study was performed using medical records, panoramic radiographs, and pathological reports. Data gathered included age, gender, location, chief complaints, effects on dentition, and treatment of odontoma and the impacted tooth associated with odontoma.ResultsMost compound odontomas (46.7%) were found in the second decade and complex odontomas were not related to age. Odontomas showed no gender predilection. Fifty-five cases (75.3%) of odontomas were detected on routine dental radiographs. Sixty percent of compound odontomas occurred in the canine area and 57.1% of complex odontomas in the molar areas. Impaction of permanent teeth (61.6%) was the most common complication on the adjacent teeth. Most odontomas (84.9%) were removed surgically and impacted permanent teeth were managed by surgical removal (53.2%), orthodontic treatment (25.5%), or surgical repositioning (6.4%). There was a statistically significant relation between age and preservation of the impacted permanent teeth associated with odontomas (p<0.01).ConclusionEarly detection and treatment of odontomas increase the possibility of preservation of the impacted tooth. Therefore, it would be suggested that periodic panoramic examination during the first and second decade of life might be beneficial for the early detection and better prognosis of odontomas.

Odontoameloblastoma: Report of a Case

Odontoameloblastoma (OA) is an extremely rare mixed odontogenic tumor with odontogenic mesenchyme displaying the histologic characteristics of ameloblastic fibroma and complex odontoma. OA occurs predominantly in children and young adults. The majority of the tumours are associated with unerupted teeth. OA is generally asymptomatic and occurs in either jaws with slight inclination for mandible. Review of the literature exhibits only four reported cases in the posterior maxilla. This report presents an OA in the posterior region of the maxilla of an 11-yearold female. The lesion was surgically treated, no recurrence has been observed on follow-up.

Case of Compound Composite Odontome: Diagnostic Criteria for Odontomas

ABSTRACT Odontomas behave more like developmental abnormalities (hamartomas) than true neoplasms. Odontomas are developmental anomalies resulting from the growth of completely differentiated epithelial and mesenchymal cells that give rise to ameloblast and odontoblast. Odontomas are classified as complex odontoma and compound odontomas. The purpose of the article is to enumerate the diagnostic criteria for odontomas.

Plasmocitoma ósseo solitário de mandíbula com apresentação imaginológica incomum: relato de caso clínico

The solitary plasmacytoma is a monoclonal unifocal neoplastic proliferation of plasma cells with histopathologic characteristics similar to those of multiple myeloma. Its etiology is unknown, and rarely the jaws. VMS patient, 56 years old, female, melanoderma in treatment of breast cancer, referred to oncologist for the preparation of the oral cavity in order to start the radiotherapy treatment. On physical examination, presence was seen as a fluctuation in the region of mandible body, with granulation tissue and purulent drainage without dental involvement. In-radiographic examination showed the presence of intraosseous lesion long, radiopaque, surrounded by radiolucent halo. The chance of diagnosis was chronic osteomyelitis diffuse, cement-osseous dysplasia, complex odontoma, osteoma and ossifying fibroma. After biopsy, was found to be a plasmacytoma. The objective of this work is to present a clinical case report of solitary bone plasmacytoma with primary involvement of the oral cavity, emphasizing their clinical, radiographic and histological features.

Histopathological and radiographic evaluation of rat molar teeth after traumatic injury-a pilot study

Objective:Radiographic and histopathological evaluation of mechanical trauma on the development of maxillary molars in rat.Materials and Methods:Experimental study with 7-day-old five new born Wistar rats. Trauma induced on 7th postnatal day with #55 K file. Right first molar region of the maxilla was the experimental side, and the left side as control. Each animal was sacrificed for histopathological observation on 8th day (immediately next day of injury), 10th day (after 3 days of injury), 13th day (Enamel completion), 19th day (Emergence into oral cavity) and 42nd day when all the teeth came into functional occlusion.Results:On the 42nd day experimental side of the study, the 1st molar tooth had not erupted and the radiographs taken revealed conglomerate mass suggestive of complex odontome. Reduced tooth size, altered enamel and dentin formation, abscess formation and complex odontome like structure were observed histopathologically.Conclusion:The diversity of morphlogical and histopathological changes to intrusive force implies intricate mechanism involved in tooth development.

Ameloblastic fibro-odontoma in the mandible of a 15-year-old male

A 15-year-old male presented with an incidentally discovered radiopacity above an unerupted wisdom tooth of the right mandible. A biopsy 2 years prior was inconclusive. Light microscopy of the biopsy revealed proliferating cords of odontogenic epithelium with a moderately cellular mesenchymal matrix enclosing loose stellate reticulum-like areas. There was associated new enamel and dentine formation with the structure of a complex odontoma. These features are of an ameloblastic fibro-odontoma. Ameloblastic fibro-odontoma is a rare, slowing growing, mixed odontogenic neoplasm which is usually diagnosed before the age of 20. They involve the posterior mandible or maxilla and can be associated with unerupted teeth. Radiographically the ameloblastic fibroma component appears as a well defined radiolucent area with the odontomatous component appearing as irregular radiopacities. Radiological differential diagnoses include calcifying odontogenic cyst and odontoma. Ameloblastic fibro-odontomas are generally not aggressive and can be treated with surgical curettage without removal of adjacent teeth. Recurrences have been reported. The risk of developing an amelobastic fibrosarcinoma is less than for an ameloblastic fibroma. However, follow-up is recommended.

Fusion of complex odontome with permanent mandibular molar

Odontomas are malformation of the dental tissue, arising during normal tooth development. They are usually asymptomatic, but often associated with tooth eruption disturbance. This article reports a case of complex odontome in a 23-year-male, which hampered the eruption of mandibular right second molar as well devitalization of first molar.

A variant of the Ekman-Westborg and Julin trait

Ekman-Westborg and Julin is a trait that shows multiple macrodontia and multituberculism affecting only the teeth with no other anomalies (E-WJ). The aim of this report is to present a case which appears to manifest all the clinical signs of the E-WJ trait including odontoma formation. A 18-year-old girl with gingival inflammation particularly in the maxillary insicor area was referred to the authors’ department. Panoramic, periapical and cephalometric radiographs were examined and complex odontoma associated with unerupted maxillary permanent lateral incisors was revealed. Intraoral examination revealed anterior crossbite, Angle Class III type malocclusion with mandibulary prominence and macrodontia of teeth 37, 12, 11 and 21. The patient was accepted as a new sporadic case of E-WJ. More case reports are needed to elucidate the causes and pathogenesis of this condition.

Clinical and Histopathological Investigation of Odontomas: Review of the Literature and Presentation of 160 Cases

The purpose of the present study was to evaluate the clinical and histopathologic aspects of different types of odontomas. One hundred sixty odontoma cases sent to the Institute of Oncology, Department of Tumor Pathology, Istanbul University from 1971 through 2010 were investigated. These tumors were compared by age of patient, gender of patient, localization, histopathologic type, clinical diagnosis, and clinical and microscopic features. Odontomas were classified histopathologically as complex, compound, or mixed. Of all investigated cases, 99 were complex, 57 were compound, and 4 were mixed odontomas. The mean age at diagnosis was 27.9 years, and odontomas were diagnosed most frequently at 10 to 19 years of age. From the perspective of community health, the presence of odontomas within the jaws is important because these constitute 21% to 67% of all odontogenic tumors. The present study showed 2 interesting findings that differed from previous studies. These are the lower incidence rate of odontomas within the category of odontogenic tumors and the higher incidence of complex odontomas over compound odontomas.

Odontoma kompleks pada impaksi gigi molar ketiga rahang bawah Complex odontoma in impacted mandibular third molar

Odontoma is a mixed odontogenic neoplasm composed of epithelial and mesenchymal tissues. There are: compoundodontoma and complex odontoma. Compound odontoma appears to be a radiopaque mass composed of in-groupsmall teeth. Compound odontoma is generally found in the anterior maxilla, and is double in number than complexodontoma. Complex Odontoma appears to be an irregularly-shaped mass and an amorphous radiopaque image,which is often found in the posterior maxilla. Impacted mandibular third molars occur due to either insufficientspace for teeth to grow or improper dental position. Two cases of complex odontoma-generated impactedmandibular third molar were reported. Extirpation and extraction were performed on the impacted teeth.

Peripheral ameloblastic fibro-odontoma or peripheral developing complex odontoma: report of a case

BACKGROUND. Peripheral (extraosseous) odontogenic tumors are rare. CASE REPORT. This report describes a case which illustrates the clinical and histopathological features of a lesion in an 8-year-old, healthy Caucasian girl that on purely morphological grounds would seem to be an ameloblastic fibro-odontoma, but may represent a case of a peripheral developing complex odontoma. CONCLUSION. Conservative surgical enucleation of the lesion was followed by unbcomplicated healing and no recurrence was seen.

Erratum to: Sequestrating Giant Complex Odontoma: A Case Report and Review of the Literature

Odontomas are the most common benign tumours of odontogenic origin. Due to their hamartomatous nature, they are usually asymptomatic but can cause impaction of one or more teeth. They consist microscopically of all the tissue types found in a developed tooth. We present a case of a large sequestrating complex odontoma resulting in facial asymmetry, cellulitis, pain and partial loss of function. This case has significance, as odontomas of this large size have rarely been reported.

Calcifying Epithelial Odontogenic Cyst Associated with Complex Odontome of Maxilla

The term calcifying odontogenic cyst was first introduced by Gorlin in 1962 (Eshghyar et al., Acta Med Iran 44(1):59-62, 2006). The lesion is unusual in that it has some features of a cyst but also has many characteristics of a solid neoplasm (Cysts and tumors of odontogenic origin: textbook of oral pathology, 2006). It is classified into two types-Type I-the cystic variant, Type II-solid tumor variant. This case report present Type I B-odontome producing intraosseous calcifying odontogenic cyst and Type I C-with ameloblastomatous proliferation in a 19years old male patient in the right maxillary quadrant. The lesion involved an unerupted permanent maxillary central incisor, which was displaced to the infraorbital ridge of right side and the radiograph revealed a calcified mass in the periapical region of right incisor that was later recognized histopathologically as complex composite odontoma. The lesion was removed surgically. This case report emphasizes on the presence of this Type I B and C lesion and the need to keep them in follow up.

Cemento-Osseous Dysplasia-Like Lesion and Complex Odontoma Associated with an Impacted Third Molar

We present a case of a 36-year-old female with a benign fibro-osseous lesion consistent with cemento-osseous dysplasia (COD) that was located coronally to the crown of an impacted mandibular third molar tooth and was associated with a complex odontoma. The pathogenesis of this unusual association is discussed and the odontogenic origin of COD is suggested.

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.

Erupting complex odontoma of maxilla: A case report

Complex odontomas are benign odontogenic tumours composed of enamel, dentin, cementum and pulp tissue. These are usually asymptomatic, but often associated with tooth eruption disturbances. In exceptionally rare cases odontomas spontaneously erupt into the oral cavity. Herewith, a case of complex odontoma in right maxilla is described which partially erupted into the oral cavity. The panoramic radiograph revealed complete radiopaque mass with impacted tooth placed deeper to it. In the present case there was no contributory history of trauma or injury and corresponding tooth was missing. So it might have been developed from the corresponding dental lamina.

Cemento-osseous dysplasia of the jaw bones: key radiographic features

The purpose of this study is to assess possible diagnostic differences between general dentists (GPs) and oral and maxillofacial radiologists (RGs) in the identification of pathognomonic radiographic features of cemento-osseous dysplasia (COD) and its interpretation. Using a systematic objective survey instrument, 3 RGs and 3 GPs reviewed 50 image sets of COD and similarly appearing entities (dense bone island, cementoblastoma, cemento-ossifying fibroma, fibrous dysplasia, complex odontoma and sclerosing osteitis). Participants were asked to identify the presence or absence of radiographic features and then to make an interpretation of the images. RGs identified a well-defined border (odds ratio (OR) 6.67, P < 0.05); radiolucent periphery (OR 8.28, P < 0.005); bilateral occurrence (OR 10.23, P < 0.01); mixed radiolucent/radiopaque internal structure (OR 10.53, P < 0.01); the absence of non-concentric bony expansion (OR 7.63, P < 0.05); and the association with anterior and posterior teeth (OR 4.43, P < 0.05) as key features of COD. Consequently, RGs were able to correctly interpret 79.3% of COD cases. In contrast, GPs identified the absence of root resorption (OR 4.52, P < 0.05) and the association with anterior and posterior teeth (OR 3.22, P = 0.005) as the only key features of COD and were able to correctly interpret 38.7% of COD cases. There are statistically significant differences between RGs and GPs in the identification and interpretation of the radiographic features associated with COD (P < 0.001). We conclude that COD is radiographically discernable from other similarly appearing entities only if the characteristic radiographic features are correctly identified and then correctly interpreted.
