BACKGROUND: The habit of inserting foreign objects into body cavities is seen in children and in adults with intellectual disability. Usually, the foreign objects cause chronic inflammation and local tissue destruction, which give rise to symptoms. Diagnosis at an asymptomatic stage is uncommon when the history is not suggestive. We describe a rare case where a foreign object was misdiagnosed as an odontoma in a patient with an alveolar cleft. CASE PRESENTATION: A radiopaque round mass was noted on the radiograph of a 12-year-old Sinhalese boy who was awaiting an alveolar bone graft...

Erupted odontomas occur very rarely in both the primary and permanent dentitions. The present case report discusses an unusual erupted odontome associated with a primary first mandibular molar. A 7-year-old female patient with an erupted odontome in the oral cavity was reported. The surgical extraction of odontome was performed under local anesthesia to allow eruption of underlying premolar tooth. After 4 years of follow-up, the first premolar had erupted with an unusual occlusal morphology, similar to that of a primary first molar...

The aim of the authors was to report a clinical case about immediate implant placement after the removal of complex odontoma. A 35-year-old female patient presented to private service complaining about absence of lower right first premolar. The computed tomographic showed radiopaque attenuation, surrounded by a narrow radiolucency in the area of dental absence, suggesting a mineralized lesion. The surgical removal of lesion was performed by intraoral access with general anesthesia and the implant of 3.75 × 10 mm (Neodent) was placed with the aid of a surgical guide, following the drill sequence established by the manufacturer...

Two adult long-finned ocellaris clownfish ( Amphiprion ocellaris) from 2 different aquaculture facilities were examined at the University of Florida, Tropical Aquaculture Laboratory for oral masses. Incisional biopsies were obtained from the masses under anesthesia, and histologic examination revealed both to be odontomas. Most benign odontomas are classified as hamartomas (disorganized proliferations of tissues found normally at the site of origin). Odontomas have previously been reported in wild teleost fish in association with viral infections and pollution...

Dental abnormalities in archeological material such us concrescence or odontoma are rare cases often found accidentally, mostly during routine X-ray analysis or during macroscopic examination of the mastication apparatus. In this study, we present a rare case of concrescence between an upper left third molar and a supernumerary fourth molar in a 19th century skull from Uganda. Simultaneously, it is a critical revision of earlier studies on the same object (which considered this abnormality as an odontoma), using dental X-ray imaging and histological analysis...

Ameloblastic fibroodontoma is a benign mixed odontogenic neoplasm considered in patients with asymptomatic swelling and unerupted teeth that exhibit histologic features between ameloblastic fibroma and complex odontoma. Radiographically, this lesion appears as radiolucency admixed with focal radio opaque masses of irregular shapes and sizes. This lesion is confirmed by the presence of proliferating odontogenic epithelium, ectomesenchyme, and dental hard tissue formation on pathological analysis supplementing clinical and radiographic findings...

INTRODUCTION: The adenomatoid odontogenic tumor (AOT) associated with odontoma has been described as a new entity with overlapping features of adenomatoid-like structures and odontoma. Presentation of the case: We report the second case of AOT associated with odontoma in the posterior maxillary region. A 22-year-old patient presented expansion of the vestibular and palatine cortical wall of maxilla. Radiographic examination and computed tomography confirmed erosion of maxillary walls, root resorption, displacement of a neighboring tooth and radiopacities within the lesion...

INTRODUCTION: Odontomas are considered as benign tumors of odontogenic tissue origin and are more over non-aggressive. They can also be categorized as hamartomas and are a result of developmental malformation of odontogenic tissues. As the name suggests, they are composed of mature tooth substances. They possess limited and slow growth potential and are well differentiated. They can be ectodermal, mesodermal or mixed in origin. Mixed variety may be further divided into compound or complex depending upon their radio-graphical resemblance to the tooth...

Odontomas are the most common odontogenic hamartomas worldwide. Depending on the level of organisation of the tissues inside, these can be differentiated into compound type or complex type. As these are asymptomatic and do not cause any changes in the bone, they are often diagnosed during the routine dental examination. Complex odontomas are commonly found to occur in posterior mandible while compound odontomas are found in the anterior maxilla. A nine-year-old female child reported for a routine dental check-up, when a missing left permanent mandibular lateral incisor [32] was noticed...

Supernumerary teeth are teeth that are present in addition to normal teeth. Although several hypotheses and some molecular signalling pathways explain the formation of supernumerary teeth, but their exact disease pathogenesis is unknown. To study the molecular mechanisms of supernumerary tooth-related syndrome (Gardner syndrome), a deeper understanding of the aetiology of supernumerary teeth and the associated syndrome is needed, with the goal of inhibiting disease inheritance via prenatal diagnosis. We recruited a Chinese family with Gardner syndrome...

We report the spontaneous occurrence of oral neoplasms in pickhandle barracuda Sphyraena jello Cuvier, 1829 from Parangipettai, on the southeast coast of India. A total of 11736 fish were examined, of which 43 were affected with oral tumours, with an overall prevalence of 0.37%. Gross and clinical symptoms included reddish to grayish-white distended tumourous growths on the gingiva, intra-oral bones and tongue. The tumours exhibited delayed eruption and intra- or extra-oral swelling, varied in consistency from extremely firm to fleshy and released mucinous material...

Odontomas are one of the most common Odontogenic Tumors of the jaw. The exact etiology of odontomas is unknown. Histologically they are composed of various formations of dental tissue (enamel, dentin, cementum and sometimes pulp). In the WHO classification, they are divided into complex odontoma and compound odontoma. Clinically, odontomas are generally asymptomatic and only in rare cases cause swelling, pain, suppuration or bony expansion. Radiologically, the tumor is initially lucent, but with time, it develops small calcifications, which eventually coalesce to form a radiodense lesion with a lucent rim...

REVIEW
Paul M Speight, Takashi Takata
The latest (4th) edition of the World Health Organization Classification of Head and Neck tumours has recently been published with a number of significant changes across all tumour sites. In particular, there has been a major attempt to simplify classifications and to use defining criteria which can be used globally in all situations, avoiding wherever possible the use of complex molecular techniques which may not be affordable or widely available. This review summarises the changes in Chapter 8: Odontogenic and maxillofacial bone lesions...

INTRODUCTION: Pierre Robin sequence (PRS) is a rare disorder classically observed as a triad of features including micrognathia, glossoptosis, and upper airway obstruction. It is associated with a syndrome in about 60% of cases. While odontogenic tumors are common findings in patients with familial adenomatous polyposis and nevoid basal cell carcinoma syndromes, PRS has not been found to be consistently associated with any tumors of the jaw. CASE REPORT: The current report aims to describe a patient with PRS who presented with an extensive ameloblastic fibro-odontoma (AFO) of the maxilla...

Odontoameloblastoma (OA) is a mixed odontogenic tumor that is an ameloblastoma with concurrent histologic evidence of odontoma differentiation. As a mixed tumor, OA is a tripartite lesion comprised of neoplastic odontogenic epithelium, induced dental ectomesenchyme (dental pulp), and mineralized dental matrix. Although rare, OA represents a diagnostic conundrum, as it is histologically closely related to 2 other mixed odontogenic tumors: odontoma (complex and compound) and ameloblastic fibro-odontoma. Herein we describe an OA arising from the mandible of a 4-mo-old Fischer 344 rat that had been exposed in utero to the mutagen ENU (N-ethyl-N-nitrosourea), and a naturally occurring lesion in a 2-y-old Appaloosa horse...

Primordial odontogenic tumor (POT) is a rare lesion in the jaw which has been included as a new entity of benign mixed epithelial and mesenchymal odontogenic tumour in the latest World Health Organization (WHO) classification (2017). Only seven cases have been reported. It typically occurs in the posterior mandible. We report an additional case of POT in the maxilla of an 8-year-old girl presenting with an asymptomatic buccal enlargement. A well-defined, unilocular, radiolucent lesion was observed radiographically...

Peripheral ameloblastic odontoma is a rare variant of odontogenic tumor occurring in the extraosseous region. The present report describes a spontaneous tumor in male Sprague-Dawley (SD) rats. The clinically confirmed nodule in the right mandibular region was first observed when the rat was 42 weeks and remained until the terminal sacrifice date when the animal was 48 weeks of age. At necropsy, a well demarcated nodule, approximately 2.5 × 2.0 × 2.0 cm, protruded from the ventral area of the right mandible...

BACKGROUND: Odontomas are the most common benign odontogenic tumors (especially in children and adolescents) and consist of odontogenic ectomesenchyma and odontogenic epithelium with the formation of dental hard tissues. They are also simply considered hamartomas. The WHO Classification defines them as complex and compound odontomas. The diagnosis is often occasional, in conjunction with x-ray routine examinations, or it is suggested by eruption disorders or abnormal position of teeth in the dental arch...
