TRATAMENTO E ANÁLISE HISTOPATOLÓGICA DE ODONTOMA COMPLEXO: RELATO DE CASO

Odontoma is a benign calcifying odontogenic tumor of unknown etiology, although local trauma, genetic factors, and chronic inflammation may be related. They are classified into compound and complex types, depending on the morphological, radiographic and histological characteristics. Clinically they hardly show signs or symptoms, and, when present, are related to delayed tooth eruption, cortical bone expansion and tooth displacement. Although radiographic exams are complementary, most cases of odontomas reported in the literature are found on routine radiographs. The diagnostic hypothesis is confirmed by histopathological examination that shows evidence of the presence of enamel, dentin, cementum and pulp tissue arranged in the form of denticles (compound) or a disorganized mass (complex). The treatment consists of surgical excision of the lesion. The aim of this article was to report a clinical case and histopathological analysis of a complex odontoma associated with an unerupted tooth, located on the left side in the posterior region of the maxilla, discovered by routine radiographic examination of a 57-year-old male patient. The treatment was surgical excision of the lesion, removal of the unerupted tooth and histopathological examination, which confirmed the diagnosis of complex odontoma. The case was followed-up clinically and radiographically for one year and showed no recurrence.

Dentigerous cyst in the maxilla: case report in a pediatric patient

Dentigerous cysts are the second most common odontogenic cysts of the jaws, and sometimes inhibit the eruption of teeth. Almost all of the dentigerous cyst encloses the crown of an unerupted tooth and the radiolucent area is attached to the tooth at the cementoenamel junction. Dentigerous cyst is more common in male patients and most commonly develop in the second and third decades of life. Clinically, a localized swelling of the alveolar bone can be detected, however, dentigerous cysts can be asymptomatic during a long period of time, leading to a significant destruction of bone. The conventional treatment plan is cyst removal and marsupialization. Marsupialization therapy can be useful to promote the spontaneous eruption of the involved tooth within the cyst. However, tooth eruption does not always occur spontaneously after marsupialization. This article aims to report a clinical case of the diagnosis and treatment of a dentigerous cyst in the maxilla associated with an unerupted canine in a pediatric patient and discussion of the treatment performed.

Ameloblastic Transformation of a Primarily Diagnosed Dentigerous Cyst of Jaw- A Rare Case Report

The separation of the follicle from around the crown of an unerupted tooth causes formation of dentigerous cyst. It may undergo metaplasia in several cases. In this case a 30 year old female patient reported with a history of dentigerous cyst with respect to impacted 48. The swelling started growing gradually causing facial asymmetry. On intraoral examination the swelling seem to extend from 48 to 46 region and cortical plates were expanded. The histopathological examination revealed the sample to be cystic ameloblastoma (mural variety). This paper sends a message that the potential of a cyst should never be understated, instead it must be kept in an observation or understanding the biological behavior over a course of time.

Revisiting King Appliance Space Regainer in Children: A Case Report with 1-Year Follow-Up

In recent times, for successful resolution of space discrepancies, a plethora of interceptive measures involving nonextraction approaches have been employed judiciously. Immaculate diagnosis and treatment planning help to prevent failure in diagnosing a case of space discrepancy and space regaining. This article describes a case in which space loss in the posterior quadrant of mandibular arch was successfully regained by employing King Appliance space regainer in an adolescent male, following which successful eruption of unerupted tooth took place. Additionally, after 1 year of follow-up, no marked reduction in arch dimension was seen.

Bilateral ectopic third molar in the maxillary sinuses associated with dentigerous cyst: a case report

A dentigerous cyst is an epithelial-lined odontogenic cyst formed by an accumulation of fluid between the reduced enamel epithelium and the crown of an unerupted tooth. About 70% of dentigerous cysts occur in the mandible and 30% in the maxilla and the most involved teeth are maxillary canines and maxillary third molar. Dentigerous cysts often displace the related tooth into an ectopic position. In the maxilla when the cyst expands into the sinus, usually causes total or partial occupation of the sinus cavity and can extend to the nose. We report a rare case of a 24-year-old female with bilateral maxillary third molars inside the maxillary sinuses attached to a dentigerous cyst and treated with a minimally invasive endoscopic surgery through the middle meatal meatotomy.

Pindborg tumour: A case report

The calcifying epithelial odontogenic tumor (CEOT) is a benign epithelial odontogenic lesion that accounts for less than 1% of all odontogenic tumors. CEOT is usually asymptomatic and an incidental radiological finding, often presenting as a mandibular radiolucency with flecks of calcified material. We report a case of CEOT in the right posterior maxilla of a 24-year-old female that was associated with an ectopic unerupted tooth. The tumour in this case caused mild pain and appeared radiographically similar to an odontoma or Ameloblastic fibro-odontome, due to its dense calcified contents. Diagnosis was confirmed through histopathology. This case report highlights the unusual clinical and radiographic appearence of Pindborg tumor.

Massive Dentigerous Cyst within the Anterior Part of The Mandible: A Case Report

Dentigerous cysts are the most common developmental odontogenic jaw cysts, associated with crowns of an Unerupted tooth. Usually, they occur in the second and third decade of life with a male predilection. They are frequently asymptomatic and mostly discovered incidentally on routine dental radiographic examination. Its growth is slow, and can reach a considerable size causing bone expansion and displacement of teeth. Mandibular lower third molars are the most frequently effected teeth; dentigerous cysts involving impacted mandibular canines are rarely reported. Surgical enucleation with extraction of the associated tooth is the standard treatment for dentigerous cyst, marsupialization is recommended for large lesions. We report a rare case of a large dentigerous cyst in a 62-year-old male patient, associated with impacted left mandibular canine, extending from the retro-molar area of left side crossing the midline to the 2nd premolar in the other side, that was successfully treated by marsupialization followed by enucleation and removal of the impacted tooth.

Imaging of odontogenic keratocyst of the jaw by panoramic radiography: a scoping review

Objectives: This review article is aimed to determine the imaging of odontogenic keratocyst of the jaw by panoramic radiography. Review: This research is a descriptive research using the scoping review method based on the Preferred Reporting Items for Systematic Review and Meta-analysis Scoping Review (PRISMA-Scr) which was conducted from February 2021 to April 2021. The search for literature related to the research topic was carried out through database of scientific articles on PMC NCBI, Pubmed NCBI, and Garuda as well as hand searching. The identified articles were screened by checking for duplicates, reading the titles and abstracts, and reading the entire articles. A total of 16 articles were included out of 161 articles in total. Conclusion: Imaging of odontogenic keratocyst of the jaw by panoramic radiography is most commonly found in the 1st and 2nd decades of life and in males, the lesions are unilocular or multilocular radiolucent and have an envelopmental shape in which the outline of the cyst surrounds the entire unerupted tooth. OKCs have well-defined with sclerotic or scalloped margins, most often occur in the posterior mandible and often associated with impacted 3rd molars, root resorption was a rare occurrence.
