Odontomas are the most commonly occurring odontogenic tumors, which are considered by many to be hamartomas rather than neoplasms. These clinically asymptomatic tumors are classified into complex and compound odontomas. They are usually discovered in radiographs and rarely cause bony expansion or infection. This paper discusses a case report of a c...

... Routinely it can be detected by radiography giving information about minute details of the lesion. The presence of such lesions may influence the adjacent structures and causing pathological alterations like devitalization, impaction, mobility etc. 4,9 Odontomas are usually small but some can grow more than 8-10 cm leading to extensive expansion of underlying jaw bones and prominent facial asymmetry. The case under discussion revealed conglomerated radiopaque mass involving right of anterior maxilla which were similar to those found by other researchers. ...
Odontomas are benign asymptomatic lesions associated with delayed eruption or detected accidently on radiographic examination. This is a case report of female patient aged eight years with chief compliant of non-eruption of maxillary central incisor. On radiographic examination, multiple denticles were seen hindering path of eruption of permanent central incisor. The treatment protocol followed was surgical removal of odontoma encouraging eruption. Early recognition allows better prognosis by preventing alterations in surrounding hard and soft tissues.
... The term odontoma was coined by Paul Braco in 1867. According to WHO, odontomas are malformations or hamartomas in which the dental tissues are formed in more or less disorderly manner because the odontogenic cells do not reach the state of normal morpho-differentiation [6]. ...
... Although the aetiology of odontoma is not very clear, local trauma, infection, family history and genetic mutation could be possible causes for its occurrence [6]. Odontomas arise from odontogenic epithelium and mesenchyme which produce enamel and dentin through odontoblastic differentiation. ...
... Due to the lack of periodontal ligament, eruption of odontomas is different from normal tooth. Bone remodelling and pressure caused due to sequestration of overlying bone caused due to increase in size of odontoma led to occusal movement and eruption of odontoma [6]. ...
Odontomas are the most common type of odontogenic tumor composed of dental tissues such as enamel, dentin, pulp and sometimes cementum. They are benign, slow growing, asymptomatic and may be diagnosed during routine clinical intraoral examination or on radiographic examination. They may sometimes interfere with the eruption of an associated tooth or may erupt in the oral cavity causing malposition of the tooth. Present case report is a case of complex odontoma in the posterior region of the mandible erupted in the place of 2 nd molar.
... Studies performed worldwide suggest that hybrid odontogenic tumors can be found [15][16][17][18][19][20]. AFO in most cases is a small lesion; however, cases with a great variety of shapes and sizes are describing occurrence both in the maxilla and mandible [8,[16][17][18][19][20][21][22][23][24][25]. The recurrence rate is highly related to the surgical approach, localization, and structures involved in its composition [1][2][3][4][5][18][19][20][21][22][23][24][25]. ...

... Differential diagnostics should include pathologies with similar mixed radiological appearances such as calcifying epithelial odontogenic tumor (CEOT), calcifying odontogenic cyst (COC), immature complex odontoma, adenomatoid odontogenic tumor (AOT), ameloblastic fibrodentinoma (AFD) [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. During clinical differentiation, bone swelling should be distinguished from odontogenic cysts (OC), eruption cysts, OKC (odontogenic keratocysts), cyst-related pathologies, and rarely with PHP, primary hyperparathyroidism tumors, namely Brown tumors related to the parathyroid gland adenomas or related lesions [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. ...
The occurrence and manifestation of each ameloblastic fibro-odontoma (AFO) is quite rare and uncommon. Mentioned odontogenic tumor classification had changed over the years; however, the treatment possibilities for this lesion remain the same. In most cases surgical enucleation is sufficient enough; however, bigger lesions might require bone curettage with sometimes performed bony ostectomy, which is a quite sufficient and effective method of treatment. In the presented case report, a panoramic radiological evaluation indicated an impacted molar tooth surrounded with mixed radiolucent/radiopaque areas. The 10-year-old Caucasian girl was scheduled for an incisional biopsy. The bone cavity in the mandible after tumor removal might be left for spontaneous healing or grafting techniques, depending on the shape and size of the defect. In the presented case report, the usage of PRF/iPRF in the mandibular bone cavity, and healing improved the overall final result.

A különböző tanulmányok az odontomákat a leggyakoribb odontogén daganatok közé sorolják. A WHO besorolás szerint az elváltozás a benignus daganatok közé tartozik, azonban más nézetek alapján inkább hamartomának tekinthető. A tanulmány célja a hazai és külföldi szakirodalmat alapul véve az odontomákhoz kapcsolódó információk összefoglalása, fókuszálva az elváltozás diagnosztikus és terápiás módjaira.
Az odontomák pontos eredete ismeretlen. Néhány teória szerint bakteriális és virális infekciók, trauma, mutációk és abnormális gének is vezethetnek odontomaképződéshez. Gyakran alakulnak ki odontomák örökletes szindrómák (Gardner-, Hermann-, Gorlin-Goltz- és otodentális szindróma) részeként is.
Leggyakrabban az első két évtizedben jelennek meg, nemi eloszlás tekintetében nem mutatnak különbséget. Különféleképpen csoportosíthatjuk az odontomákat, a leggyakoribb a WHO klasszifikáció, amely szerint két típust különböztethetünk meg: a compound odontomát és a complex odontomát. Diagnosztikájuk kiegészítő vizsgálatok nélkül meglehetősen bonyolult lehet, ugyanis tünetszegények, a fogazat rendellenességei, impakció, retenció, duzzanat és/vagy aszimmetria utalhat csak a jelenlétükre. Általában röntgenfelvétel során kerülnek felfedezésre, pontos diagnózisuk csak hisztopatológiai vizsgálat után mondható ki.
Az odontomák terápiája sebészi eltávolítás, ami történhet extraorális és intraorális megközelítésből is. A műtét során egyre gyakoribb a modern készülékek (lézer, ultrahangos/piezo-/ sebészet) használata. Szövődményekre a legtöbb esetben nem kell számítani.

Odontomes are considered as hamartomatous developmental anomaly. According to WHO (2005) there are two types of odontomas: complex composite odontome and compound Composite odontome [1]. The term is now used to denote lesions that contain all dental tissues and include two types, complex and compound odontoma, which contains tooth like structures. Most of these tissues does not resemble any morphological similarity with normal tooth structures; however enamel, dentin, pulp, cementum are arranged as in normal tooth structure. Compound odontome is more common in anterior maxilla, While complex odontome are usually found in posterior mandibular region. Compound Composite odontome are more commonly found as compared to complex odontome [1]. They are usually found until 2nd decade of life. The etiologies of the odontomas were elusive and may be contributed by various factors such as growth pressure, local trauma, infection,Developmental and hereditary inuences [2]. Odontome found in 3rd and 4th decade of life are usually rare. Patient usually present for routine dental problems like pain, swelling and pus discharge.
... The strength of the trauma or constant pressure on the forming tooth germ can cause morphological changes leading to odontoma development. The developing tooth germ is replaced by its malformation [12]. The absence of the second and third maxillary molar teeth may suggest that the odontogenic tumour emerged as an abnormality in the tooth germ formation process. ...
... In the second phase, calcification occurs partlythat's why the radiopacity is seen.

Odontome appears to be in the final stage in this case, which is a radiopacity surrounded by a radiolucent edge. ...
... The enamel, dentine and pulp thus laid down are in an abnormal pattern as the odontogenic cells are usually disorganized. 1 The etiology of odontome is unclear, with infection, trauma and syndromes being considered as etiological factors. ...
... Compound odontomas are found to occur more often in the anterior region of the jaw (61%) and complex odontomas are found in the posterior segment (59%), with higher occurrence in the right than in the left side. 1 Odontomes rarely erupt in the oral cavity. Due to the lack of periodontal ligament, their eruption varies from the eruption of a normal tooth. ...
... The occlusal movements then causes it to erupt. 1,2 The odontome is usually detected accidentally on a routine radiograph. The common signs and symptoms include impacted permanent teeth and swelling. ...
Odontome is a developmental anomaly where dental tissues are disorganized and laid down in an abnormal pattern. Though several theories have been put forward, the etiology is still unknown. Occasionally an odontome may be associated with an impacted tooth interfering with the latter's eruption into the oral cavity. This is a case report in which a complex odontome lying superior to an impacted third molar not only prevents it from erupting but also pushes it inferiorly towards the lower border of the mandible resulting in a visible bulge affecting patient's esthetics. To make things worse, the close proximity of the inferior alveolar nerve along with a dilaceration of the impacted third molar made treatment planning a difficult task.
... Histologic sections revealed a mixture of radiopaque material composed mainly of dental tissues, consisting of immature dentin, enamel, enamel matrix, cementum, and pulp tissue. Histopathologic examination confirmed the diagnosis of complex odontoma (Figure 4(a)) [24]. ...
... Odontomas are common odontogenic tumors and are usually asymptomatic [17]; however, in this case, the patient experienced pain in the region of the third molar, probably due to the presence of inflammatory component of the lesion with exudate drainage. Odontomas rarely erupt [24] but when this occurs, they are different from a normal tooth because of the lack of the periodontal ligament. The increase in size leads to sequestration of the overlying bone, causing pressure and possible movement in the occlusal direction, leading to eruption. ...
... The increase in size leads to sequestration of the overlying bone, causing pressure and possible movement in the occlusal direction, leading to eruption. In this case, the tumor led to retention of the right third molar, which is a common characteristic in odontomas, although not reported in clinical cases with tuberosity of the maxilla [12], because there is high predilection of complex odontoma in the posterior region of the mandible [12,24]. Most complex odontomas reported in the literature typically measure around 1-2 cm [3]. ...
Odontomas are the most common benign tumors of odontogenic origin. They are normally diagnosed on routine radiographs, due to the absence of symptoms. Histopathologic evaluation confirms the diagnosis especially in cases of complex odontoma, which may be confused during radiographic examination with an osteoma or other highly calcified bone lesions. The micro-CT is a new technology that enables three-dimensional analysis with better spatial resolution compared with cone beam computed tomography. Another great advantage of this technology is that the sample does not need special preparation or destruction in the sectioned area as in histopathologic evaluation. An odontoma with CBCT and microtomography images is presented in a 26-year-old man. It was first observed on panoramic radiographs and then by CBCT. The lesion and the impacted third molar were surgically excised using a modified Neumann approach. After removal, it was evaluated by histopathology and microtomography to confirm the diagnostic hypothesis. According to the results, micro-CT enabled the assessment of the sample similar to histopathology, without destruction of the sample. With further development, micro-CT could be a powerful diagnostic tool in future research.
