Odontomas are mixed epithelial and mesenchymal tumor-like malformations (hamartoma) composed of dental hard and soft tissue, causing delayed teeth eruption. Multiple case reports have been published in the literature describing solitary, localized odontoma features in pediatric patients along with their treatment planning. This report presents clinical and radiographic features of gigantic multiple odontomas involving both jaws in a five-year-old boy.

The odontoma is regarded as a hamartomatous process of the jaws. Most are discovered as an incidental radiographic finding, averaging 15 mm in size. This report describes a case of a diminutive odontoma that was surgically removed before the onset of eruptive and pathologic consequences. A compilation of documented complications and syndromes associated with odontomas is also presented.

A 7-month-old, male, Weimaraner dog was presented for maxillary swelling. Clinical evaluation including radiographs and computed tomography revealed a large cystic lesion, unerupted right maxillary canine tooth, and mass presumed to be a compound odontoma. The cyst and mass were expansile and occupied a large portion of the nasal cavity displacing anatomical structures of the maxilla. The mass was excised via curettage through an intraoral surgical approach and the unerupted tooth and cystic lining were removed. Histopathology supported dentigerous cyst and compound odontoma. This case confirms the first report of concurrent development of dentigerous cyst and compound odontoma in a dog with successful treatment and 18-month follow-up with no recurrence.

Peripheral or extraosseous odontogenic tumors are rare oral soft tissue enlargements which demonstrate the same histologic features of their intraosseous counterparts but emerge in gingiva and mucosa. In this paper we report a case of peripheral odontoma in a 12-years-old female patient presented asymptomatic swelling in the palatal site. After the clinical and radiographic examination, excisional biopsy was applied to the lesion located entirely in the soft tissue of maxillary incisors. Histopathologically presence of tooth-like structures containing dentin with regular canals and partly enamel matrix were observed. Our aim is to present the extremely rare case of peripheral odontoma and to review the literature for demonstrating the frequency and clinicopathologic features of this entity.

OBJECTIVE: To report a delayed tooth eruption following late surgical removal of a compound odontoma in a 10-year-old child.
BACKGROUND: Odontomas are the most common odontogenic tumors. They are usually asymptomatic and discovered during routine radiographic examinations or during an assessment of delayed tooth eruption. Odontomas are classified into compound or complex based on the microscopic structure of dental tissues. Early diagnosis and surgical removal of odontomas is the keyword for favorable results.
METHODS: This paper describes a case of compound odontomas in a 10-year-old boy that prevented eruption of the permanent mandibular lateral incisor. Extraction of mandibular primary lateral incisors and surgical excision of the compound odontomas was performed. After 3 years of follow-up, at the age of 13 years, the permanent lateral incisor erupted and approached the occlusal plane.
CONCLUSIONS: Late surgical removal of odontomas resulted in a delayed eruption of the affected teeth.
CONCLUSIONS: Surgical removal of odontomas and regular follow-up to monitor the eruption of the affected teeth should be considered for the teeth with an open apex before considering orthodontic traction.

Odontomas are the most common odontogenic tumors worldwide and are usually chance findings seen on routine dental examinations. However, on progression, they may be associated with adjacent tooth displacement.
We report a case of an 11-year-old girl who presented at the Lagos University Teaching Hospital (LUTH) pediatric dental clinic with a complaint of painless enlargement of the left anterior maxilla of 2-years duration. The swelling was located between teeth 21 and 22 and was associated with distal displacement and mesial angulation of tooth 22. Clinical, radiographic and histopathologic investigations revealed a compound odontoma. Surgical exposure and enucleation was done to remove the tumor. The patient\'s postoperative course and 6 months follow-up were uneventful.
This report elucidates the importance of routine dental check-ups and minimally traumatic management of odontomas in pediatric dental patients to prevent adverse effects of odontomas, thereby, minimizing the interventions needed after surgical enucleation.
Les odontomes sont les tumeurs odontogènes les plus courantes dans le monde et sont habituellement des découvertes fortuites observées lors des examens dentaires de routine. Cependant, lors de leur progression, ils peuvent être associés à un déplacement des dents adjacentes.
Nous rapportons le cas d’une jeune fille de 11 ans qui s’est présentée à la clinique dentaire pédiatrique du Lagos University Teaching Hospital (LUTH) pour se plaindre d’un élargissement indolore du maxillaire antérieur gauche depuis deux ans. Le gonflement était situé entre les dents 21 et 22 et était associé à un déplacement distal et à une angulation mésiale de la dent 22. Les examens cliniques, radiographiques et histopathologiques ont révélé un odontome composé. Une exposition chirurgicale et une énucléation ont été effectuées pour retirer la tumeur. L’évolution postopératoire du patient et son suivi à 6 mois se sont déroulés sans incident.
Ce rapport met en évidence l’importance des contrôles dentaires de routine et de la prise en charge des odontomes par des moyens peu traumatisants chez les patients pédiatriques afin de prévenir les effets indésirables des odontomes et de minimiser ainsi les interventions nécessaires après l’énucléation chirurgicale.

A 12-year-old Japanese boy was referred to our hospital for evaluation of a radiopaque area on the left side of the mandible. Radiographic and computed tomographic examinations revealed a radiopaque lesion located on the lingual side, along with permanent tooth eruption. Several small tooth-like structures were noted within the lesion and the mandibular left second premolar was inclined in a mesial direction. An odontoma was clinically diagnosed and surgical removal by an endoscopic intraoral approach under general anesthesia was planned. Reports of oral surgery using an endoscopic approach have been presented, though none for an odontoma. With the expectation that removal of the odontoma would improve dentition in this case, we planned future management. A minimally invasive surgical removal procedure by an endoscopic intraoral approach from the lingual side was performed and good early recovery was noted. The resected tumor consisted of several small tooth-like structures. Histopathological diagnosis was a compound odontoma. One-year follow-up findings showed that the post-surgical course was good.

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.

This report describes a clinical case of asymptomatic compound odontoma in the anterior left side of the maxilla associated with an impacted canine and supernumerary tooth with a gubernacular canal of a 47- year-old female with no relevant medical history. Cone-beam computed tomography (CBCT) was performed for precise three-dimensional localization of each structure and assessment of their spatial relationship with the associated structures before surgery. The treatment protocol involved surgical enucleation of the odontoma and open extraction of both impacted and supernumerary teeth. The patient had uneventful healing and proceeded with the prosthodontic treatment plan. The dentist should be aware of the probability of a close relationship between the development of odontoma and presence of the gubernacular tract, which could be used as a future radiographic diagnostic criterion of an odontoma. Also, we recommend that more studies be performed in this field to deeply analyze the imaging characteristics of GT and its spatial association with various pathological lesions in the future.
