Central odontogenic fibroma is an extremely rare benign tumor, accounting for less than 0.1% of all odontogenic tumors. The most recent literature review that only 69 cases have so far been reported. This tumor has a slow persistent growth that results in painless cortical expansion clinically, and well defined unilocular or multilocular radiolucent lesion. Root resorption of associated teeth is common, and lesions located between the teeth often cause root divergence. There is occurring tendency to female more than male, and occurring in the mandible and in the maxilla with equal frequency. The treatment is surgical excision with no tendency to undergo malignant transformation. We report a case of central odontogenic fibroma in the maxilla of a 27-year male with literatures review.

Odontogenic myxoma is one of rare tumors in oral and maxillofacial region and it is thought to be mesenchymal or ectomesenchymal origin. Its characteristics are benign and non-metastatic but it has the potential of local invasion and high recurrence rate. It originally occurs in atrium of heart and in central case, my xoma is located mainly in the maxilla and mandible. Most odontogenic myxoma develops in 2nd or 3rd decades of life and rarely occurs in child or older persons over fifty. The distribution of reported cases between the sexes is similar and the maxilla and mandible are equally affected or slightly higher in mandible. Clinically it is usually asymptomatic, however it can cause pain and paresthesia is complained in the advanced stages. Displacement and mobility of teeth have also been reported. Odontogenic myxoma is not a frequent tumor, but in case of slow and painless growing tumor it must be considered as a differential diagnosis.

Purpose : 1. Retrospectively evaluate the accuracy of tentative diagnosis or impression from the clinico-radio-graphic materials of jaw lesions which showed mixed lesions associated with teeth. 2. To observe the diagnostic importance of the calcified part of the lesions which appear as radiopaque areas. Materials and Methods: 14 cases of jaw lesions which showed mixed lesions associated with teeth were reviewed. These lesions were mostly diagnosed as adenomatoid odontogenic tumors (6 cases) or calcifying odontogenic cysts with (4 cases) or without odontomas (4 cases). The calcified elements of the lesions which demonstrated various sizes and patterns of radiopaque shadows resembled odontoid tissues in some cases but could not be defined in some other cases radiographically. Results : The final histopathologic diagnosis confirmed adenomatoid odontogenic tumors in 4 of the 6 cases. The remaining 2 cases turned out to be odontoma and ameloblastic fibroodontoma. The 4 cases of calcifying odontogenic cysts with odontomas were correct in 3 cases but remaining 1 case was just odontoma. The 4 cases of calcifying odontogenic cysts were proved to be odontogenic keratocyst, calcified peripheral fibroma, unicystic ameloblastoma and squamous cell carcinoma. Conclusion : The diagnostic accuracy of the adenomatoid odontogenic tumors and calcifying odontogenic cysts were high when the lesions show typical appearance. The calcifications which show radiopaque areas could be odontomas or dystrophic calficifations or remnants of bone fragments from resorption.

The peripheral odontogenic fibroma (WHO type) is a relatively rare and characteristically benign and unencapsulated, exophytic gingival mass of fibrous connective. Odontogenic epithelium is found within the gingival mass, but usually appears to playa minor role when compared to the fibrous component. The connective tissue is ranged from markedly cellular to relatively acellular and well collagenized. but the connective tissue in this case report appears less cellular. Peripheral odontogenic fibroma must be differentiated histologically from peripheral ossifying fibroma, Peripheral cemental epithelial odontogenic tumor and Peripheral ameloblastoma. The author reports the following conclusions after clinical and radiological examination, excisional biopsy and reviewing literatures. 1. Peripheral odontogenic fibroma is rare lesion and frequently occurs in interdental papila as a form of fibroblastic connective tissue including odontogenic epithelium within the lesion. 2. Peripheral odontogenic fibroma must be differentially diagnosed with Peripheral ossifying fibroma by including less cellular connective tissue, odontogenic epithelium and dysplastic dentin 3. Treatment consists of surgical excision including removal of alveolar bone which is eroded under the lesion

Keratocystic odontogenic tumor (KCOT) is a common benign tumor of osseous lesions in dental and maxillofacial practice. We describe three cases of large KCOT located in the posterior part of the mandible extending to the angle and ramus region, which were enucleated via sagittal split osteotomy (SSO) of the mandible. There are cases in which a conventional enucleation procedure does not ensure complete excision of the entire lesion without damage to vital structures like the inferior alveolar nerve. In such cases, a SSO approach could be a better choice than conventional methods. The purpose of this article is to describe our experience using unilateral mandibular SSO for removal of a KCOT from the mandible.

Objectives: Since World Health Organization reclassified the odontogenic keratocyst as a keratocystic odontogenic tumor(KCOT) in 2005, management of KCOT remains controversial. The purpose of the this study is to present a current concept of the treatment of the KCOT. Methods: Recent articles were focused on the method of the surgical therapy and the recurrence rate of KCOT. Results: The treatment modality is divided into conservative treatment-such as simple enucleation with or without curettage or marsupialization-and aggressive treatment including peripheral ostectomy, chemical curettage with Carnoy's solution, and resection. Conclusions: Keratocystic odontogenic tumors have higher recurrence rates than other odontogenic lesions; thus, the selected type of treatment is very important.

The odontogenic myxoma is an infiltrative benign tumor of bone that occurs almost exclusively in the jaw bones and comprises 3% to 6% of odontogenic tumors. This neoplasm is thought to arise from the primitive mesenchymal structures of a developing tooth, including the dental follicle, dental papilla, or periodontal ligament. Radiographically the odontogenic myxoma may produce several patterns: unicystic, multilocular, pericoronal, and radiolucent-radiopaque, making the differential diagnosis difficult. In this report, two cases of the odontogenic myxoma in the jaw bones are presented. The first case involved only the mandible, while the second case involved the maxilla. Both cases presented extensive multilocular radiolucencies characteristic of odontogenic myxoma.

A central odontogenic fibroma is a rare benign tumor composed of mature fibrous connective tissue with variable amounts of odontogenic epithelium. It appears at similar rates in the maxilla and mandible. In the maxilla, it usually occurs anterior to the molars. Radiographically, central odontogenic fibroma commonly presents as a multilocular or unilocular radiolucency with a distinct border. This paper reports a case of an aggressive central odontogenic fibroma involving the right posterior maxilla of a 53-year-old man. Radiographs showed an extensive soft tissue mass involving the entire right maxilla with frank bone resorption. The patient had a history of 2 operations in the region, both more than 2 decades ago. Although it was impossible to confirm the previous diagnoses, it was presumed that this case was a recurrent lesion.

Objectives: This study aimed to determine the prevalence of odontogenic cysts, tumors, and other lesions among reports in the archives of the Department of Oral and Maxillofacial Surgery at the Faculty of Dentistry affiliated with Kocaeli University collected over a four-year period. Materials and Methods: In this retrospective study, patient records from the archive of the Department of Oral and Maxillofacial Surgery from 2014 to 2018 were reviewed. Patient demographic information (age and sex) and lesion location were recorded and analyzed. Results: From a total of 475 files reviewed, odontogenic cyst was confirmed in 340 cases (71.6%), and odontogenic tumor was confirmed in 52 cases (10.9%). Regarding odontogenic cyst type, the most common was radicular cyst (216 cases), followed by dentigerous cyst (77 cases) and odontogenic keratocyst (23 cases). Among odontogenic tumors, the most frequent was odontoma (19 cases), followed by ossifying fibroma (18 cases) and ameloblastoma (9 cases). Giant cell granuloma was also reported in 35 cases. Conclusion: The distribution pattern of odontogenic cysts and tumors in our retrospective study is relatively similar to that reported in the literature. Complete clinical reports for final diagnosis of these lesions and routine follow-up examinations are very important for treatment.

The odontogenic keratocyst (OKC) was originally classified as a developmental cyst, and OKC is histologically divided into orthokeratic and parakeratic types. According to revised histopathological classification of odontogenic tumors by the World Health Organization (2005), the term, keratocystic odontogenic tumor (KCOT) has been adopted to describe parakeratic OKC. The KCOT is noted for its capacity to recur after treatment. The aggressive, or potentially aggressive, nature of KCOT has led to alternative treatments. Among the treatments is noted the use of Carnoy's solution as adjunctive intralesional therapy having a low rate of recurrence. This study suggests a possible benefit of Carnoy's solution against recurrence of KCOT.
