Compound Odontoma in Anterior Mandible-A Case Report

Management of Mandibular Compound Odontoma With Numbness in the Lower Jaw

Odontomas are considered to be among the more common odontogenic tumors in the oral cavity. Several authors classify them as hamartomas instead of actual tumors. Odontomes' precise etiology is still unknown. The majority of odontomas are found during routine radiography studies and are asymptomatic. Odontomes typically cause disruptions to the teeth's eruption, most frequently deflection or delayed eruption. Here, the reported study details the surgical management of a mandibular compound odontoma in a patient who presented with a complaint of numbness in his lower jaw.

Complex-compound Odontome with 526 Denticles: A Unique Case Report

Aim

To report a unique case presentation of a complex-compound odontome with 526 denticles.

Background

Odontoma is a hamartoma of the jaws that has both epithelial and mesenchymal components differentiating to form enamel and dentin. It is of compound and complex types. Rarely, the features of both the types are present together in what is called the compound-complex type of odontoma.

Case description

The case report discussed here is that of a 7-year-old boy who presented with a compound-complex odontoma in the right posterior mandibular region.

Conclusion

Timely diagnosis and prompt surgical treatment aid in preventing complications and bony expansion. Thus, proper histopathological examination is essential for the confirmation of odontoma. Recurrence of odontoma is rare and usually has a favorable prognosis if diagnosed early.

Clinical significance

The odontome contained 526 denticles, the maximum reported in the literature so far, making this a case of extreme clinical significance.

Odontomas are associated with impacted permanent teeth in orthodontic patients

Background

Odontomas are the most frequent odontogenic tumors in the oral cavity and can result in failure of eruption of permanent teeth or be associated with impacted teeth.

Material and Methods

The present study evaluated the prevalence of complex and compound odontomas in non-syndromic patients prior to the onset of orthodontic treatment. Panoramic radiographs of 4,267 non-syndromic patients were evaluated; 22 cases were included being 54.5% complex and 45.4% compound odontomas.

Results

The sample was composed predominantly by White males with mean age of 14.5 years. Complex odontomas were commonly found in the maxilla (83.3%) while compound type was mostly located on mandible (60%), presenting a significant association (P=0.027). Moreover, odontomas were significantly associated with impacted teeth (P<0.0001). The most frequently odontoma-associated impacted teeth were lower canines, followed by upper central incisors and upper canines, while impacted teeth with no odontoma were predominantly upper canines, lower second premolars and upper second premolars. Compound and complex odontomas showed mean size of 10.5 and 7.25 mm, respectively, presenting significant association between lesion size and odontoma type (P=0.021).

Conclusions

Odontomas affected mainly White male patients with mean age of 14.5 years, being the complex type commonly found in the maxilla and the compound type mostly located on mandible. Furthermore, odontomas were significantly associated with impacted teeth, affecting mainly lower canines. Early diagnosis and correct treatment are essential to avoid any complications, such as prolonged retention of primary teeth and delayed eruption of permanent teeth.

Anxiolysis in the Surgical Management of a Compound Odontoma in a Pediatric Patient

Among odontogenic tumors, odontoma is the most frequent. The common treatment contemplates a conservative approach. While this procedure is generally accepted and tolerated, some difficulties may be encountered in the case of pediatric patients. Indeed, negative feelings of tension, apprehension, nervousness, and fear are likely to occur. The present report is aimed at discussing the management of a compound odontoma in a pediatric patient under anxiolysis with diazepam on an outpatient basis. The surgery was carried out without complications, and the discharge was completed safely. Oral premedication with diazepam should be considered to avoid more invasive sedation procedures in anxious pediatric patients.
