BACKGROUND: Odontomas are among the most common odontogenic tumors and are generally considered as hamartomatous odontogenic lesions. These tumors can be histopathologically divided into complex odontomas and compound odontomas based on their composition. Odontomas show a slow growing behavior and typically lack characteristic symptoms. The standard surgical treatment for large odontogenic tumors is a mandibular (continuity) resection followed by primary or secondary plastic reconstruction.
METHODS: A 22-year-old male presented to the Department of maxillofacial surgery with an increasing feeling of pressure in the left mandible. An orthopantomogram revealed a large complex odontoma rg 038. Instead of mandible continuity resection an alternative minimally invasive technique/approach (intraoral) with a trapezoidal bone flap for the enucleation of an odontoma of the mandibular angle with subsequent flap reimplantation and osteosynthesis was performed.
CONCLUSIONS: Surgical enucleation of large mandibular odontoma with a continuity resection through an extraoral approach represents the surgical standard treatment of this entity. The present case report describes an alternative minimally invasive technique/approach. This technique may reduce surgical risks of the continuity resection through an extraoral approach (nerve damage, scarring) and can improve the long-term stability of the mandible by bone preservation.

UNASSIGNED: The objective of this case report is to offer insight into an expansive compound-complex odontoma located in the anterior maxilla of a 15-year-old male. The focus is placed on the importance of early detection and the progressive comprehension of odontomas.
UNASSIGNED: Odontomas are common odontogenic lesions that are frequently discovered during examinations for delayed tooth eruption. There are two distinct classifications for odontomas-compound odontomas and complex odontomas. With its own each set of characteristics. A timely diagnosis is critical for avoiding complications.
UNASSIGNED: A male individual aged 15 years exhibited an expansive compound-complex odontoma located in the anterior maxilla. The clinical examination showed delayed tooth eruption and asymptomatic swelling. The radiographic images showed a radiopaque mass with tooth-like structures and radiolucent borders affecting the surrounding dentition. A surgical excision procedure was conducted, followed by a subsequent histopathological examination confirming the diagnosis of compound-complex odontoma. The patient continued orthodontic treatment after a 1-year follow-up without recurrence.
UNASSIGNED: This case emphasizes the importance of regular dental exams in detecting odontomas early. This observation also highlights the growing understanding of odontomas as hamartomatous odontogenic malformations and the challenges of diagnosing them clinically. Additional molecular investigations are required to facilitate the classification and elucidation of genetic factors.

Odontomas are considered hamartomatous lesions and are one of the two most common odontogenic tumors of the jaw. Odontomas are classified as compound or complex. Recently, ameloblastic fibro-odontoma (AFO) and ameloblastic fibro-dentinoma were reclassified as developing odontomas. Though clinically odontomas are usually asymptomatic, they have adverse effects on adjacent teeth such as tooth impaction, delayed eruption, displacement of teeth, over-retention of teeth, and can give rise to odontogenic cysts within the jaw. We sought to evaluate the clinicoradiopathologic presentations of odontomas by collecting and analyzing the clinical, radiographic, and pathologic data of odontomas diagnosed in our institution from 2013 to 2022. Over this 10-year period, there were 242 patients with a histopathological and/or radiographic diagnosis of odontoma. There was no gender predilection and ages ranged from 3 to 101 years (median, 14 years). The second decade of life was the most prevalent (57.4%). There was no jaw predilection; however, the anterior jaw was the most common location. Ninety-four (38.8%) cases presented with clinical findings. The most common finding was tooth impaction (n = 83). Nine (3.7%) cases were histopathologically confirmed to be associated with other lesions such as dentigerous cysts (n = 8) and nasopalatine duct cyst (n = 1). The median age (25 years) of patients diagnosed with odontomas associated with cysts was older than patients with odontomas (14 years) without associated cysts. Compound odontomas were the most common type of odontoma compared to complex and AFOs with 71.4%, 26.6%, and 2%, respectively. The majority of compound odontomas involved the anterior jaw (69.3%) and mandible (54.9%) while the majority of complex odontomas involved the posterior jaw (59.6%) and maxilla (54.7%). The four AFOs were in the posterior jaw and 75% involved the maxilla. The median age (12 years) of patients diagnosed with AFO was the youngest compared to patients diagnosed with compound (13 years) and complex (16 years). In conclusion, we analyzed the clinical, radiographic, and pathologic features of 242 new cases of odontomas. Our study reaffirms that odontomas frequently affect the pediatric population and can disrupt their dentition. Based on the result of this study, our clinical recommendation to prevent problems to adjacent teeth from odontomas is for dentists to be apt in the diagnose of odontomas to ensure that they are surgically removed in a timely manner.

Odontomas are the most common odontogenic neoplasms. They are generally small and asymptomatic. This article presents an unusual case of a giant maxillary complex odontoma, which obscured a part of the maxillary antrum and impacted a tooth. This was discovered during an episode of maxillofacial cellulitis. In this case, surgical excision of the lesion was performed under general anesthesia, and the closure was performed with a fat pad pedicled flap. A brief review of the literature was performed to analyze the characteristics of this clinical entity and their implication in the treatment.

UNASSIGNED: Odontoma is the most common odontogenic tumor. A literature review revealed limited data for odontomas in Taiwan. This study evaluated the radiographic characteristics of odontomas in 1280 patients in the National Taiwan University Children\'s Hospital (NTUCH).
UNASSIGNED: This retrospective study analyzed the odontomas based on examination of mainly panoramic radiographs and related radiographs of 1280 patients in the NTUCH. Chi-square test was used for trend analysis.
UNASSIGNED: Among 1280 patients (710 boys and 570 girls), a total of 16 patients with odontomas (10 boys and 6 girls) were identified. There were 14 compound and 2 complex odontomas. The mean age of the patients was 10.38 years with the majority of odontomas occurring in the first (37.5%) and second decade (62.5%) of life. Odontomas had a marked predilection for the mandible (56.25%) and for the anterior region of the jaws (75%), particularly for the anterior maxilla (43.75%). Ten odontomas (62.5%) were associated with the impacted corresponding permanent teeth. The sagittal position of odontomas and vertical relation of odontomas to the corresponding permanent teeth were significantly correlated with the eruption rate of corresponding permanent teeth (P < 0.05).
UNASSIGNED: The odontomas occur most commonly in male patients with a male to female ratio of 1.67:1. The incidence of odontomas in our 1280 patients is 1.25%. The age range of patients with odontomas is 6-17 years. The most frequent location of odontomas is the anterior maxillary region. Odontoma is frequently associated with an impacted corresponding permanent tooth.

BACKGROUND: and importance: Complex odontomas are hamartomas representing a conglomeration of all dental tissues. When developed, they rarely become giant and even more rare to become giant in children. This report presented an unusual giant mandibular complex odontoma in very young patient. It also provided a literature analysis and better understanding of clinical features of such giant lesions in the mandible.
METHODS: An 8-year-old boy presented with swelling in the right side of the mandible. After clinical and radiological exams, a provisional diagnosis of giant composite odontoma was made. This lesion led to jaw expansion, asymmetrical face, and teeth eruption alterations. Surgical excision of the lesion was performed, and histopathological examination confirmed the diagnosis. The patient\'s follow-up showed that normal jaw size and facial symmetry was restored with no evidence of recurrence for 3 years.
UNASSIGNED: A literature review of reported mandibular large odontomas was made. All published reported cases of giant odontoma in the mandible caused bone expansion with or without pain. According to the literature, this paper described the youngest patient with giant complex odontoma in the mandible. This was also the first reported case from Syria.
CONCLUSIONS: Giant complex composite odontoma of the mandible can develop at any age causing facial asymmetry, however, with good prognosis and predictable surgical treatment.

Odontomas are known as the most common odontogenic tumor and usually present without clinical symptoms. It can be divided into compound odontoma and complex odontoma. Compound odontomas are calcified tissue and they bear similarity to the teeth, whereas complex odontomas do not show similarity to the tooth. Diagnosis of the odontomas is usually accidental on radiographic examination. Complex odontomas are commonly seen in the posterior mandible. Apart from the few case reports regarding the complex odontoma of the anterior mandibular region, reported occurrence in this site is rare. Here, authors described a case of a child who presented with a chief complaint of swelling in the anterior mandibular canine region. After clinical examination and required investigations, provisionally, it was diagnosed as complex odontoma. It was surgically removed and histopathological examination confirmed the provisional diagnosis. How to cite this article: Ahammed H, Seema T, Cheranjeevi J.

Ameloblastic fibro-odontoma is a rare tumor affecting the pediatric population and young adults. The World Health Organization (WHO) in 2005 defined it as \"A neoplasm composed of proliferating odontogenic epithelium in a cellular ectomesenchymal tissue with varying degrees of inductive changes and dental hard tissue formation.\" There exists a controversy on its histogenesis designating it as a hamartoma (developing complex odontoma [CO]) or a true neoplasm since both the lesions appear similar histologically. Recently, the WHO in 2017 has clubbed both these lesions as the same entity. Most cases are reported in males and in mandible, while cases in maxilla are scarce. This article describes a recurrence of a previously reported case of ameloblastic fibroma which showed maturation into AFO or CO in a girl aged 6 years in the posterior maxilla. This case is reported due to its rarity and a brief review with differential diagnosis is also discussed.
