“…Routine panoramic radiography is part of the diagnostic investigation for pathology screening. However, panoramic radiography cannot rule out other diagnoses whose radiological features can be similar to that of ameloblastomas [27]. These include odontogenic keratocyst, fibromyxoma, fibrosarcoma, haemangioma, aneurysmal bone cyst and giant cell tumour.…”

Introduction: Ameloblastoma is the most common benign tumour of odontogenic origin in Africa and presents five times more in the mandible than the maxilla. The presentation of ameloblastoma in the mandible is unique due to its anatomical variation and hence the aim of this study was to analyse the radiographic and histopathological features of ameloblastoma involving the mandible. Materials and methods: This was a retrospective, descriptive study of all histopathologically diagnosed ameloblastoma of the mandible over a period of 45 years. Patient demographics, radiographic and histopathological features were recorded and compared to previous studies. Results: A total of 148 lesions were included. The male to female ratio was nearly equal (1.05:1). The majority of patients were below 50 years of age (83.77%) and were black African (58.8%). The posterior region was the most affected site with majority of lesions presenting with multilocular appearance (68.24%) and root resorption (66.38%). Histologically, conventional ameloblastoma was the most common variant (48.65%). Conclusions: Mandibular ameloblastoma had a higher predilection for black African patients with higher prevalence of mixed density lesions when compared to previous studies. The size of lesions in this sample was considerably larger than those reported in previous studies. In addition, lesions in this sample also exhibited marked cortical expansion as well as root resorption.

“…It was first described in 1855 by Maisonneuve as "buttery cyst" but finally named as "odontogenic keratocyst" in 1956 by Philipsen [2,3]. It originates from dental lamina remnants or from the overlying epithelium basal cells [4]. The OKC can be unique or multiple, and sometimes associated with a basal cell nevus syndrome (previously known as Gorlin or Gorlin-Goltz syndrome) [5,6].…”

Though odontogenic keratocysts (OKCs) are benign lesions, they have a high recurrence rate. Because of their aggressive behavior, they have been classified as tumors by the WHO until 2017. Main differential diagnoses are amelobastoma and dentigerous cyst. Anatomopathological examination can reach a final diagnosis. Several treatments have been proposed: curettage, resection, enucleation (alone or together with peripheral ostectomy) and decompression. Decompression aims to decrease the volume of the lesion of “large” OKCs, in order to prevent surgery-related fractures and to preserve the surrounding important anatomical structures such as the inferior alveolar nerve. It could lead to a complete regression. If not, secondary enucleation can be performed in better conditions: a reduced volume to remove, a thicker epithelium to detach, a lower risk to damage neighboring anatomic structures and a lower recurrence rate. Long-term follow-up however remains necessary. Nowadays, minimally invasive surgery prevails. And since OKC was returned into the odontogenic cysts group in the WHO classification, decompression should be considered as the first intention treatment. The purpose of this paper is to provide an update about OKC features and biological mechanisms, to review the different treatment options and to provide a step-by-step protocol for decompression.

“…However, the difference in bone expansion can be used as a radiographic finding to differentiate between ameloblastomas and odontogenic keratocysts. 3 Previous studies indicated that some radiographic findings are particularly helpful for the diagnosis of ameloblastomas and odontogenic keratocysts, such as buccolingual expansion, the number of locules, internal density, and root resorption of the adjacent teeth. [4][5][6][7] However, to the best of our knowledge, no study has ever attempted to analyze the width (buccolingual expansion) of lesions in relation to their length (anteroposterior dimension) in this context.…”
