Incidentally detected odontoma within a dentigerous cyst

Imaging approach for jaw and maxillofacial bone tumors with updates from the 2022 World Health Organization classification

Jaw and maxillofacial bone lesions encompass a wide variety of both neoplastic and non-neoplastic pathologies. These lesions can arise from various tissues, including bone, cartilage, and soft tissue, each presenting distinct challenges in diagnosis and treatment. While some pathologies exhibit characteristic imaging features that aid in diagnosis, many others are nonspecific. This overlap often necessitates a multimodal imaging approach, combining techniques such as radiographs, computed tomography, and magnetic resonance imaging to achieve a diagnosis or narrow the diagnostic considerations. This article provides a comprehensive review of the imaging approach to jaw and maxillofacial bone tumors, including updates on the 2022 World Health Organization classification of these tumors. The relevant anatomy of the jaw and dental structures that is important for accurate imaging interpretation is discussed.

Odontoma Recurrence. The Importance of Radiographic Controls: Case Report with a 7-Year Follow-Up

Odontomas are benign tumors characterized by slow and limited growth with a rare recurrence. Odontomas are generally detected by radiographic findings in the radiopaque stage, where calcification of the tissues is observed. This article seeks to report the recurrence of a radiologically diagnosed odontoma to show the importance of radiographic controls after enucleation as a diagnostic and follow-up method. Case report: A female patient, 9 years old, attended dental care in 2020 due to malpositioned teeth. In the intraoral clinical examination, she presented stage II mixed dentition with crowding. A radiographic exam showed no associated lesions. The patient reported a history of odontoma removal and a supernumerary tooth in sextant II in 2016. Subsequently, she was referred to orthodontics, where permanent dentition with moderate anterior crowding in the maxilla and mandible was observed. The radiographic examination showed a radiopaque area compatible with odontoma, palatal to teeth 12 and 13. Conclusions: Although recurrence is rare, complete removal in the case of an odontoma is critical. This study demonstrates the importance of performing radiographic controls 5 years after enucleation of an odontoma, considering the stages of evolution.

Compound Odontoma Associated with Dentigerous Cyst Incidentally Detected in an Adult Patient: Tomography and Histological Features

Odontoma is the most common benign odontogenic tumor of epithelial and mesenchymal origin. The standard treatment involves a conservative approach. While this procedure is generally well accepted and tolerated, some difficulties may arise in case of odontomas associated with cystic lesions. In general, the expansive nature of cystic lesions requires their surgical excision, different from isolated nonsymptomatic odontomas that can be monitored radiographically. However, to the best of our knowledge, there is scarce evidence currently available reporting on the presence of odontoma-associated cystic lesions in the oral cavity. Therefore, the present case report is aimed at describing the diagnostic clinical, radiological, and histological features together with the surgical management of a dentigerous cyst associated with a compound odontoma. Following surgical removal of the lesion, no recurrence was observed after 12 months of follow-up.

Mystery Behind a Broken, Discolored Right Maxillary Central Incisor: A Case Report

Odontoma is a hamartomatous benign odontogenic tumor that may resemble tooth-like structures. Odontomas can impede the eruption of the permanent underlying tooth or can cause devitalization of the tooth resulting in pain and swelling near the tooth, causing diagnostic dilemmas to the dentist. We describe a case of an unusual occurrence of such an odontoma in a 31-year-old male patient in the periapical region of a broken, discolored maxillary central incisor tooth causing a diagnostic dilemma and its treatment.

Surgical management of compound odontomas: piezoelectric surgery or rotary instruments? A clinical study

BACKGROUND

Odontomas are odontogenic tumors with a clinicopathological heterogeneity and a variable biological behavior. They usually are asymptomatic and can be discovered by routine radiographic investigations. This study aims to examine and compare intra- and postoperative consequences associated with use of piezosurgery and conventional rotary instruments for the removal of these oral lesions.

METHODS

Clinical and histological data of 120 consecutive patients with a mean age of 22 years and 1 month (age range from 19 years and 1 month to 25 years and 3 months) with compound odontomas, diagnosed by biopsy, were assembled. Of a total of 120, 100 oral lesions were placed in the anterior region of the maxilla; of these, 50 were extracted through traditional rotary instruments (GROUP 1) and 50 with piezoelectric surgery (GROUP 2). The remaining 20 oral masses took place in the posterior area of the same bone; of these, 10 were extracted through traditional rotary instruments (GROUP 1a) and 10 with piezosurgery. (GROUP 2b). The piezoelectric cutting device was (Mectron Medical Technology) with MT1-10 insert, pump level 4, vibration level 7. Finally, pain, swelling, and surgical time evaluation were measured 24-48-72 hours after the intervention.

RESULTS

As regards the mean time of surgery, in Group (1 and 1a) were 12 minutes, while in Group (2 and 2a) were 18 minutes. Regarding surgery, the osteotomy of the cortical bone was performed in all cases. As regards the measure of bone saved, calculated through a surgery gauge, it was greater of 3.2 mm in Group (2 and 2a) than in Group (1and 1a). The main of facial swelling in both Groups (1 and 1a) was 5.82 mm and 2.23 mm for the Groups (2 and 2a) immediately after surgery.

CONCLUSIONS

Piezosurgery produced less postoperative discomfort about the swelling. It is an effective technique in daily surgical practice, especially as regards the safety of soft tissues, bone, and nerves.
