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...

Gardner syndrome is known as a variant of familial adenomatous polyposis. This syndrome is characterized by multiple intestinal polyposes, osteomas, and epidermoid cysts. In addition, dental abnormalities include an increased frequency of multiple odontomas, as well as supernumerary and impacted teeth. The authors report the case of a 7-year-old male patient with Gardner syndrome. Radiographic findings revealed multiple osteomas in both sides of the maxilla, multiple diffuse enostoses in both jaws, and a complex odontoma in the left mandibular body...

The occurrence of ameloblastic fibro-odontoma (AFO) in the oral region is unusual and accounts for 1-3% of all odontogenic tumors. AFO presents mixed radiopaque patterns within the lesion with diverse findings; therefore, it is important to compare this tumor with other odontogenic tumors that radiographically present with calcified bodies. Herein, we observed the calcification patterns within the lesion in seven AFO cases (five males, two females; mean age, 8.3 years; age range, 4-13 years). Periapical and panoramic radiographs were obtained from all seven cases...

INTRODUCTION: The ameloblastic fibro-odontoma (FOA) is a rare benign tumor representing 1-3% of odontogenic tumors. The FOA affects young patients before the age of 20. Surgical treatment allows usually for recovery. Recurrence and malignant transformation are possible. OBSERVATION: A 3-year-old patient, with no medical and surgical history, was referred for a painless swelling of the right cheek progressing for several months. Radiographic examination showed a large mixed lesion...

The purpose of this paper is to describe the case of surgical management of massive compound odontoma with 36 denticles in a 9-year-boy who presented with a complaint of pain and swelling in mandibular left posterior region and retained 74. The denticles were removed after the removal of retained 74 completely and wound healing was observed. Odontomas are considered as hamartomatous dental malformation rather than true neoplasm of odontogenic origin. They are the most commonly occurring abnormally formed dental tissues that interfere with eruption of associated teeth...

Odontomas are the most common benign odontogenic tumors of the oral cavity; however, their occurrence in the primary dentition is an extremely rare condition. When associated with primary teeth, odontomas may lead to disturbances in tooth eruption, which often requires a multidisciplinary treatment approach. The purpose of this paper is to review the literature on odontomas of the primary dentition and discuss the management of a compound odontoma in a pediatric patient.

The area of the oral vestibule is often a place where pathologies appear (e.g., peripheral odontomas). The origin of these pathologies is not fully understood. In the present study, we traced a cell population expressing Sonic hedgehog (Shh) from the beginning of tooth development using Cre-LoxP system in the lower jaw of wild-type (WT) mice. We focused on Shh expression in the area of the early appearing rudimentary incisor germs located anteriorly to the prospective incisors. The localization of the labelled cells in the incisor germs and also in the inner epithelial layer of the vestibular anlage showed that the first very early developmental events in the lower incisor area are common to the vestibulum oris and the prospective incisor primordia in mice...

BACKGROUND: Odontogenic tumors such as ameloblastic fibro-odontoma (AFO) are rare conditions in children and are often asymptomatic. AFOs are found by routine clinical and radiological examination or when they cause obvious intra- or extra-oral swelling. MATERIALS AND METHODS: A case of an AFO in a 7-year-old girl is described, and 107 cases from the literature and this report are analyzed. RESULTS: The total of 108 cases revealed the average age at presentation of AFO to be 6...

Because of cellular senescence/apoptosis, no effective culture systems are available to maintain replication of cells from odontogenic tumors especially for odontoma, and, thus, the ability to isolate human odontoma-derived cells (hODCs) for functional studies is needed. The current study was undertaken to develop an approach to isolate hODCs and fully characterize the cells in vitro. The hODCs were cultured successfully with a Rho-associated protein kinase inhibitor (Y-27632) for an extended period with stabilized lengths of the telomeres to sustain a similar phenotype/property as the primary tumoral cells...

REVIEW
Elisabetta Mancinelli, Vittorio Capello
The order Rodentia comprises more than 2000 species divided into 3 groups based on anatomic and functional differences of the masseter muscle. Myomorph and sciuromorph species have elodont incisors and anelodont cheek teeth, unlike hystrichomorph species which have full anelodont dentition. Diseases of incisors and cheek teeth of rat-like and squirrel-like rodents result in a wide variety of symptoms and clinical signs. Appropriate diagnostic testing and imaging techniques are required to obtain a definitive diagnosis, formulate a prognosis, and develop a treatment plan...

Ameloblastic fibro-odontoma (AFO) is a mixed odontogenic tumor that presents epithelial and mesenchymal components. Ameloblastic fibro-odontoma is generally diagnosed between the first and second decades of life and normally shows a slow clinical growth in the posterior portion of the maxilla or mandible, being mostly associated with 1 or more impacted teeth. Radiographic features of AFO show a radiolucent well-defined, uni, or multilocular defect due to containing variable amounts of calcified material. The enucleation of the tumor is the usual conduct and should be followed up for a long period of time...

Odontomas are the most common odontogenic tumors of the oral cavity which are nonaggressive, hamartomatous in nature consisting of enamel, dentin and cementum. They are called as composite because they contain more than one type of tissue. They are generally asymptomatic, hence recognised on routine radiologic examination. The compound odontoma is composed of multiple small tooth like structures, whereas the complex odontoma consists of a conglomerate mass of enamel and dentine, which bears no anatomical similarity to the tooth...

PURPOSE OF REVIEW: The management of benign, locally aggressive odontogenic tumors, namely, keratocystic odontogenic tumors (KOTs) and ameloblastomas, can be challenging. The purpose of this article is to briefly summarize important features of these lesions and review recent trends in the literature regarding their treatment. RECENT FINDINGS: Currently, KOTs are frequently treated with a conservative approach consisting of enucleation and adjuvant decompression or local microablation with peripheral ostectomies, Carnoy's solution, or cryotherapy...
