A 19-year-old male patient reported to dental OPD of our institution with a swelling in the posterior part of the mandible on the left side. The patient gave a history of gradual increase in the size of swelling for 7 years. The patient also had a radiograph and histopathology slides from his previous dental visit at another facility. The radiograph revealed a well-circumscribed radiolucency with an impacted tooth (38). Histopathology slides showed features of an ameloblastic fibroma (AF). The patient had deferred the treatment for 5 years since he was young and reported to our OPD due to increase in the size of the swelling over the past few weeks. The present radiographs revealed radiolucency with radiopacity. Excisional biopsy was performed and the histopathological examination revealed an Ameloblastic fibro odontoma. This case report is to document and highlight the possible progression of AF to Ameloblastic fibro-odontoma.

A young female patient reported to the department of oral and maxillofacial surgery with complaint of asymptomatic swelling in left posterior region of lower jaw since 6 months. Complete intraoral and extraoral clinical examination was done. Routine radiographical investigations were advised. Based on clinical and radiographical findings she was provisionally diagnosed with odontoma of left mandible. It was a considerably giant mass with thinned out both cortical plates and the inferior border of the mandible. Although we assumed high risk of fracture of the mandible, successful surgical excision of the tumour was done using a minimally invasive intraoral approach and by sectioning the odontoma, sparing cortical bones. We managed to remove the whole of tumour without fracturing the mandible. Final histopathological report confirmed the initial diagnosis of complex composite odontoma. Patient is under regular follow-up.

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 ( = 83). Nine (3.7%) cases were histopathologically confirmed to be associated with other lesions such as dentigerous cysts ( = 8) and nasopalatine duct cyst ( = 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.

PURPOSE
Odontomas represent a common clinical entity among odontogenic tumors, but are not well-addressed in the Vietnamese population. The present study aimed to determine the clinical and preclinical characteristics of odontomas and associated factors in the Vietnamese population.
MATERIALS AND METHODS
This retrospective study retrieved data from histopathological diagnoses from 2 central hospitals of Odonto-Stomatology in Ho Chi Minh City, Vietnam during 2004-2017. The odontomas were classified as complex (CxOD) or compound (CpOD) subtypes. The epidemiological, clinical, and radiological characteristics of the odontomas, stratified by subtype and sex, were obtained and analyzed.
RESULTS
Ninety cases, consisting of 46 CxODs and 44 CpODs, were included. The average age of patients was 32.4 (±20.2) years. The patients with CxOD were older than those with CpOD (<0.05). Clinically, 67% of patients showed an intraoral bone expansion. Approximately 60% of patients with CxOD exhibited a painful symptom, about 3-fold more than those with CpOD (<0.05), whereas almost all patients with CpOD exhibited perturbations of dentition, unlike those with CxOD (<0.05). Radiologically, CxOD was characterized by a larger dimension than CpOD in both sexes (<0.05), and CpOD induced complications in adjacent teeth more often than CxOD (<0.05). The development of odontoma with advancing age differed significantly in odontoma subtypes related to their pathological origins, and between the sexes, resulting from different physiological states.
CONCLUSION
The findings of this study highlight the value of clinical and radiological features of odontomas and their associated factors for the early diagnosis and adequate treatment of younger patients.

The World Health Organization (WHO) classifies odontomas as odontogenic tumors, consisting of odontogenic epithelium and ectomesenchyme. They result from developmental abnormalities and, therefore, do not constitute authentic tumors. It is a local malformation that has no growth autonomy. They are rarely symptomatic and are usually discovered accidentally during the realization of a radiographic examination. There are two variants of odontomas: complex and compound. Complex odontomas are made of a mass consisting of an anarchic assembly of mineralized tissue (enamel, dentin, and cementum) and dental pulp; while compound odontomas are consisting of a set of small rudimentary teeth, assembling in clusters. They rarely show the features of both types together. The aim of this work is to report a rare presentation of an odontoma in a 24-year-old male patient, which present the characteristics of both complex and compound variants. Surgical excision of the lesion was performed. Anatomopathological examination confirmed the diagnosis. Clinical and radiological survey does not show any recurrence.

UNLABELLED
Odontomas, the benign odontogenic tumors of epithelial and mesenchymal origin, are very common in occurrence and are now widely accepted as hamartomas. Odontomes are invariably composed of enamel and dentin, and may also have variable amounts of cementum and pulp. Largely, odontomas have been categorized into the compound and complex varieties. Compound odontoma epitomizes itself as aberrations with the presence of all types of dental tissues and showing an orderly distribution in the form of tooth-like structures; whereas complex odontoma describes itself as aberrations in which the presence of some or all dental tissues and in a disorganized distribution. Herein, a case of compound-complex odontome associated with the impaction of a mandibular second premolar is being presented in a 13-year-old girl.

AIMS
To evaluate the presence of dentofacial asymmetry in patients with odontoma by panoramic radiography.
METHODS
Panoramic images with odontoma were selected among all panoramic radiographs (3058 patients). Maxillary odontoma was detected in 27 patients while mandibular odontoma was detected in 25 patients. In addition, 30 patients with similar age and gender characteristics were selected as the control group. Skeletal angular, skeletal linear and dental measurements were performed on panoramic radiographs. The odontoma region and the opposite side of the odontoma of the individuals were examined. The dentofacial asymmetry of the odontoma groups was compared with the control group. Paired t-test was used to determine dentofacial asymmetry on the right and left side of the patients with odontoma. The ANOVA test was used for testing the differences among groups.
RESULTS
As a result of study, no significant difference was found between the region of the odontoma and the symmetrical region in the maxilla and mandibula (P > 0.05). In the control group, a statistically significant difference was found in the angle between the mandibular canal and the mental foramen, lower incisor size, PFH/CutCat(°), and Co-Mc-Me(°) measurements (P < 0.05). In the maxillary and mandibular odontoma groups, a statistically significant difference was found in the angle between the mandibular canal and the menton, CH (mm), RH (mm), and CrH (mm) in the comparison of the odontoma and the control group (P < 0.05).
CONCLUSIONS
No difference was found between the right and left sides of the jaws related with the asymmetry of the maxilla and mandible.

Review
The invaginate tooth (IT) is an alteration in the development of the dental organ, which occurs as a consequence of invagination of the internal epithelium of the enamel organ. IT is also known as "dens in dente", among other denominations, and presents a series of clinical, histological and imaging characteristics. The most extreme variant of IT has a very complex configuration, and the magnitude of the intussusception has led to it also being called dilated odontoma, being a term that generates confusion in some professionals.While the term odontoma has been reported as a synonym for both IT as well as a new variant of odontomas, there is a difference betweene the two types: one is a developmental anomaly and the other is a growth with a hamartomatous appearance. However, the literature continues to use both terms to define IT, and thus, it is important to know the origin and be aware that the controversy is based on historical and customary references.

Review
Benign bony tumors of the skull base and paranasal sinuses are uncommon entities, with an overall higher incidence in males. Benign bony tumors may lead to local expansion with resultant mass effect of potentially critical structures. Some benign bony tumors may undergo malignant transformation. This article reviews the presentation and management of benign bone tumors of the skull base and paranasal sinuses with special consideration to involvement of the adjacent orbit, intracranial and critical neurovascular structures. This review covers tumor incidence, location, gross and histologic appearance as well as radiographic findings, treatment, and recurrence rates. Tumors discussed in this article include osteochondromas, osteomas, osteoid osteomas, aneurysmal bone cysts, fibrous dysplasia, giant cell tumors, cemento-ossifying fibroma, ameloblastic fibro-odontoma, ecchordosis physaliphora, chondromyxoid fibroma, primary chronic osteomyelitis, primary chronic osteomyelitis, osteochondromyxoma, and dense bone islands.
