“…They frequently lead to impaction or delayed eruption of permanent teeth. (11,12) Their pathogenesis has been associated with a number of causes including trauma during primary dentition (9,17), hereditary anomalies such as Gardner's syndrome, Hermann's syndrome, and basal cell nervous syndrome, odontoblastic hyperactivity, or alterations of the genetic components responsible for controlling dental development (8,16). The development of the odontoma is commonly associated with eruption failure of permanent teeth, impaction, and delayed exfoliation of primary teeth (17,18,19,20,21).…”

“…The compound odontoma has predilection toward the anterior maxilla (61%), whereas only 34% of complex odontomas occur in this area; the complex type shows a predilection for the posterior jaws (59%) and lastly the premolar area (7%). Both variants are made of all dental tissues such as enamel, dentin, cementum, and pulp (7,8).…”

“…Impaction has been defined as the prevention of the eruption of a tooth to the expected times into a normal functional position due to the presence of an obstacle or reasons of different nature (8,12). In all cases, surgical removal represents the best therapeutic option and the prognosis after treatment is very favorable, with very low recurrence (7,8,12,13,14,15,16,17).…”
Background: Odontomas are mixed odontogenic tumors composed of mineralized tissue of ectomesenchymal origin. According to the World Health Organization (WHO) ranks, the odontomas are classified into two main types: complex and compound. They are usually detected in routine radiographs and may be related to various causes, and are rarely associated with impacted teeth. Purpose: The aim is to present two clinical cases of complex odontoma that prevent appropriate eruption of permanent teeth.
Material and methods:We present two cases of complex odontoma associated with a retained permanent tooth. The orthopantomography and CBCT revealed circular and ovoid in shape amorphous radiopaque masses, surrounded by a thin radiolucent zone in association with an impacted permanent tooth. Results: The treatment of choice was extraction of the primary first molar, enucleation of the odontoma and the preservation of the first premolar. The complete removal of the complex odontoma was successfully performed, since after few months of follow-up the maxillary permanent teeth resumed their eruptive process. The result of the biopsy confirmed cases of complex odontoma. Conclusion: Odontomas are tumours of the dental tissues and may interfere with the eruption of the associated tooth. The early diagnosis, followed by a proper treatment at the right time, will result in a favorable prognosis and a desirable development of occlusion.

“…In most cases they are detected as incidental findings on routine radiographs [18]. In exceptional cases they may perforate the alveolar crest and become exposed to the oral cavity with resultant pain, swelling and bony expansion [19]. Pathologic changes such as impaction, malpositioning, aplasia, malformation and devitalization of adjacent teeth are associated with 70% of odontomas.…”
Odontomas are the most common benign tumours of odontogenic origin. Due to their hamartomatous nature, they are usually asymptomatic but can cause impaction of one or more teeth. They consist microscopically of all the tissue types found in a developed tooth. We present a case of a large sequestrating complex odontoma resulting in facial asymmetry, cellulitis, pain and partial loss of function. This case has significance, as odontomas of this large size have rarely been reported.
“…Odontomas are hamartomas composed of various dental tissues, that is, enamel, dentin, cementum, and sometimes pulp [2]. According to classification by World Health Organization (WHO), 1992, two types of odontoma have been recognized: (a) compound odontoma: malformations with the presence of all types of dental tissues and exhibiting an orderly distribution in the form of tooth-like structures; (b) complex odontoma: malformations in which all dental tissues are likewise represented but with a disorganized distribution [4–7]. Based on morphology, Garvey et al in 1999 have further classified compound odontoma into three types: (a) denticular type which is composed of two or more separate denticles, each resembling a tooth; (b) particulate type which is composed of two or more separate masses of particles with dental tissues abnormally arranged; (c) denticuloparticulate type where the denticles and particles are present side by side [8].…”
Eruption of tooth into extraosseous locations is an extremely rare condition. We report a case of a six-year-old girl child with tooth-like structure erupting from the right buccal mucosa. Clinical, radiographic, and histopathologic examination suggested the diagnosis of compound odontoma. Very few cases have been reported so far, where tooth has been located completely in the soft tissue and a variety of names have been used for that condition. A brief review of the literature and the ambiguity in naming the situation is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
