    Ameloblastoma of the mandible: A radiological and clinical study at the University of the Western Cape Oral Health Centre
    (University of the Western Cape, 2019) Ranchod, Sanjay; Morkel, Jean
    Ameloblastoma is the most common benign tumour of odontogenic origin and presents five times more in the mandible than in the maxilla (Reichardt et al. 1995). Although benign, it exhibits an invasive behavioural growth pattern with a high rate of recurrence if not managed appropriately. Ameloblastoma occurs in all age groups, but is most common in patients between the ages of 20 and 40 years. Males and females are equally affected. Clinically, ameloblastoma presents as a slow-growing, painless tumour, which if left untreated, can grow to enormous proportions. Radiographically, the lesion presents as either multilocular or unilocular radiolucency. The internal appearance of multilocular lesions may resemble a soap-bubble, honeycomb or spider-like pattern. Combinations of these patterns are not unusual.

    Perforation of the palate - A report of two Syphilitic Gumma cases
    (South African Dental Association, 2020) Titinchi, Fadi; Behardien, Nashreen; Morkel, Jean; Opperman, Johan
    Syphilis has recently shown resurgence in its incidence especially in immune-compromised patients. We present two cases of tertiary syphilis in middle-aged males with large perforations in the hard and soft palates, one of which had Human Immunodeficiency Virus (HIV) co-infection. Diagnosis was initially difficult due to non-specific features mimicking other conditions such as perforation of cocaine abuse aetiology, neoplastic conditions, sarcoidosis, fungal infections, bacterial infections other than Treponema pallidum and Wegeners granulomatosis.

    Prevalence of odontogenic tumours at Tygerberg oral health centre
    (Universty of the Western Cape, 2024) Lange, Johny De; Morkel, Jean
    The prevalence of odontogenic tumours differs worldwide, with different countries reporting a difference in age, gender and types of tumours seen in their respective population groups. The changing classification systems of odontogenic tumours also impacts the prevalence and frequency distribution of these tumours. The objective of this study was to determine the prevalence of odontogenic tumours in South Africa, at Tygerberg Oral Health Centre, according to the World Health Organization (WHO) classification. The secondary objectives were then to determine the demographics of these tumours in the South African population serviced by the Tygerberg Oral Health Centre and the most common location of these tumours within the maxilla and mandible.

    Residual cysts of the jaws: a retrospective study of characteristic features and management at the university of the Western Cape oral health centre
    (University of the Western Cape, 2023) Titinchi, Fadi; Morkel, Jean
    Residual cysts are infrequent inflammatory cysts of the jaws which are of odontogenic origin. They are usually preceded by a radicular cyst which has developed apical or adjacent to a carious tooth. These cysts usually present with similar features as radicular cysts; however, due to absence of the causative tooth, they can mimic more aggressive cysts and tumours on radiographs. Moreover, they have the ability to destroy bone within the jaws without any symptoms. There is paucity of studies in the literature regarding these cysts as they are often overlooked due to their lack of symptoms and innocent radiographic appearance. Hence, the aim of this study was to describe the clinical, radiological and histopathological features of residual cysts in the jaws as well as analyse their surgical management and recurrence patterns.
