Annals of International medical and Dental Research
Treatment of patients with maxillofacial defects is one of the most challenging tasks. Prosthetic reconstruction of maxillomandibular defects may be achieved with the help of removable and fixed prosthesis to restore the lost form, function and speech. The purpose of this article is to describes a case of CEOT (Calcifying Epithelial Odontogenic Tumor) in left mandibular body region managed with a treatment obturator, which allowed closure of the defect by secondary healing through granulation tissue maturation and associated bone fill. A 19 guage wire was used to stabilize the appliance, and provide retentive properties. The obturator allowed decrease in size of defect and enhanced comfort and overall wellbeing of the patient.
Calcifying epithelial odontogenic (Pindborg) tumor. A clinical case
Minerva stomatologica
Calcifying epithelial odontogenic tumor (CEOT), Pindborg tumor, is a rare benign odontogenic neoplasm representing about 0.4-3% of all odontogenic tumors. This tumor more frequently affects adults in an age range of 20-60 years, with a peak of incidence between 40 and 60 years. About 190 cases of CEOT have been reported in the dental literature. Fifty-two percent of cases of CEOT is associated with a tooth impacted and/or displaced by the tumor. The primary CEOT has a recurrence rate of 10-15%, after total excision, and its malignant transformation is a very rare occurrence. The authors report a case of primary intra-osseous CEOT, embedding the mandibular right second molar, in a 24 year-old male. Radiographs showed a well-defined unilocular osteolytic lesion, swelling and reabsorbing the mandible and displacing the inferior alveolar nerve. It was possible to perform conservative surgical treatment consisting of the enucleation of the tumor together with a portion of tumor-free bone...
Single tooth prosthetic rehabilitation of a patient with recurrent keratocystic odontogenic tumor
international journal of stomatology & occlusion medicine, 2013
Background Keratocystic odontogenic tumor (KCOT) is one of the most common odontogenic neoplasms. There are many kinds of treatment modalities which can be a conservative method, such as enucleation or an aggressive method, such as enucleation followed by cryosurgery and radical surgical tactics with bone resection. In the literature a relatively high recurrence rate reported for KCOT with a range of 5-70 % depending on the method of treatment.

The calcifying epithelial odontogenic tumor (CEOT) is a benign tumor, accounting for 0.4-3% of all odontogenic tumors. It mostly occurs in the 4 th to 6 th decades of life with equal propensity for both the genders. In about 52% of cases, the tumor is found in association with an unerupted tooth, with lower jaw being more commonly involved. It is usually asymptomatic and often causes bone expansion similar to other odontogenic tumors; therefore, diagnosis depends upon the lesion's histologic features. We report a clinical presentation of CEOT not associated with unerupted teeth and occurring in the anterior mandible of a 16 years old male. The tumor was treated by surgical removal with no sign of recurrence after a period of 6 months. The surgery required complete removal including adequate margins of normal tissue in order to ensure complete removal.
Surgical management of a large calcifying epithelial odontogenic tumor in the maxilla: A case report
International Journal of Surgery Case Reports, 2019
INTRODUCTION: The calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a locally invasive benign neoplasm. Histogenesis is controversial. PRESENTATION OF CASE: A 26-year-old male presented asymptomatic swelling on the right side of the face, with approximately six months of evolution. At intraoral examination, a hard nodule localized in the right posterior region of the maxilla, measuring approximately 5.0 x 3.0 cm was observed. The computed tomography images showed hypodense lesion with points of calcification associated with two non-erupted teeth. We suspect of odontogenic lesions. The final diagnosis of CEOT was established based on the histopathological aspects. DISCUSSION: This tumor is more frequent in adult men, usually develops in the posterior region of the mandible and may present clinical-pathological similarities with others odontogenic lesions. The radiological aspects observed in the CEOT are variable and depend on the time of evolution of the tumor. The histopathological examination is mandatory to establish the final diagnosis. CONCLUSION: Our case was treated with simple enucleation without signs of recurrence in five years of follow-up. Further studies are needed to understand the aetiology and the biological behaviour of this tumor.
Osteoradionecrosis of a Mandible: A Case Report of Implant-Supported Rehabilitation
European Journal of Inflammation, 2013
The head and neck are the sixth most common sites of cancer in the world; the survival rate at 5 years from diagnosis is 60%. Surviving patients, after the critical phase of the disease, require proper rehabilitation. The treatment of oral neoplasia, such as surgery and radiotherapy, may often determine significant disability, such as impaired speech, swallowing, mastication and facial deformity, with severe consequences on the quality of life of these patients. Dental implant-based prosthodontic rehabilitation is a consolidated technique for improving the quality of life in patients who have overcome oral cancer. Implants provide stability and support for removable prostheses in oral cavities seriously deformed by surgical treatment. Moreover, mobile prostheses have the advantage of being removable, to check the health of oral tissues and intercept possible relapses of the neoplasia. On the other hand, a lack of residual bone following resection makes it difficult to place implants in an ideal position, and patients who have been submitted to radiotherapy of the head and neck are reported to have a reduced success rate. This paper presents the case of a 67-year-old woman rehabilitated with dental implant-based prosthesis after a hemimandibulectomy due to osteoradionecrosis, without bone reconstruction.

Pindborg tumors (calcifying epithelial odontogenic tumors) are uncommon neoplasms of odontogenic origin most often located in the posterior mandible. First described in detail in 1955 by Pindborg, these tumors are considered benign but can be locally aggressive in nature, with recurrence rates of 10% to 15% reported. The malignant form of this tumor is exceedingly rare. We describe the case of a 64-year-old woman initially treated for a painful infected left mandibular third molar. The patient underwent extraction of the tooth and excision of an associated soft tissue component. Subsequent histologic review identified a Pindborg tumor of the left posterior mandible. After initial excision, this tumor recurred twice, with the recurrences exhibiting a progression to a malignant Pindborg tumor (odontogenic carcinoma) with vascular invasion and spread to a cervical lymph node. Further treatment involved radical surgery and adjuvant radiotherapy. At last review 12 months after treatment, the patient was disease free. This article describes only the second case of odontogenic carcinoma. The transformation from benign to malignant histologic findings has not previously been documented in this tumor. The salient clinical features of this case are presented along with supportive pathologic and radiologic evidence.

Patient underwent mandibular resection due to surgical therapy of oropharingeal malignoma. Facial asymmetry and cosmetic distortion are frequent consequences of such interventions, which may also include deviation and intrusion of the mandible, motor and sensory disorders, abnormal intermaxillary relations and malocclusion. Implant-supported prosthesis could be an optimal solution to prosthodontic treatment of such patients. However, there is a problem in determination of stable (interocclusal) intermaxillary relations. This article describes the choice of therapy and procedures undertaken in prosthetic rehabilitation of a patient who underwent mandibular resection and radiotherapy with supported prosthesis retained with four implants.

Calcifying epithelial odontogenic tumor is a benign neoplasm, but its local destructive potential may lead to the formation of major bone defects. Microscopically, there are some histological variants. Among them, we highlight the clear cell variant due to its more aggressive behavior and a higher incidence of relapse. In this context, it is pertinent to describe the clear cell variant of calcifying epithelial odontogenic tumor. Despite the large bone defect formed in the posterior region of the mandible, conservative treatment associated with guided bone regeneration assured complete bone formation and the absence of recurrence in an 8-year follow-up period.
