Surrogate Immunohistochemical Markers of Proliferation and Embryonic Stem Cells in Distinguishing Ameloblastoma from Ameloblastic Carcinoma.

Purpose: The current study aimed to investigate the use of surrogate immunohistochemical (IHC) markers of proliferation and stem cells to distinguish ameloblastoma (AB) from ameloblastic carcinoma (AC).

Methods: The study assessed a total of 29 ACs, 6 ABs that transformed into ACs, and a control cohort of 20 ABs. The demographics and clinicopathologic details of the included cases of AC were recorded.

Insights into dental age estimation: introducing multiple regression data from a Black South African population on modified gustafson's criteria.

Dental Age Estimation (DAE) is an effective instrument of the rule of law for verifying dubious age claims in living individuals. Once tooth development is complete, only degenerative dental characteristics can be used for this purpose. The influence of ethnicity on these degenerative dental characteristics has not been clarified.

A radiologic-pathologic study of the histopathologic variants of ameloblastomas and their proliferation indices.

Objectives: This study aimed to analyze the clinicoradiologic features and Ki-67 proliferation indices between the histopathologic variants of ameloblastomas (ABs) for possible associations.

Study Design: The diagnosis and histopathologic variant were confirmed for all cases by experienced Oral and Maxillofacial Pathologists. Immunohistochemistry for Ki-67 was performed on the most representative formalin-fixed paraffin-embedded tissue block.

The relevance of taurodontism in forensic dental age estimation.

Taurodontism is a dental morphological anomaly characterized by enlarged pulp cavities repositioned towards the apical region of the tooth, coupled with shortened root structures. Molars are commonly affected by this alteration. Certain populations exhibit up to 48% prevalences for this dental alteration, underscoring its significance in dental age estimation (DAE).

Studying eruption patterns of mandibular third molars for forensic age assessment: Introducing current reference data from a population of black South Africans.

Introduction: Evaluation of the eruption of mandibular third molars in orthopantomograms (OPGs) is a method of forensic age assessment. The objective of our study was to provide valid reference data for this trait within a population of black South Africans. The study was guided by the criteria for reference studies in age assessment.

Ultrasonography use for tongue cancer management: A scoping review.

Background: Tongue cancer is associated with debilitating diseases and poor prognostic outcomes. The use of imaging techniques like ultrasonography to assist in the clinical management of affected patients is desirable, but its reliability remains debatable. Therefore, the aim of this study is to investigate the importance of ultrasound use for the clinicopathological management of tongue cancer.

A cone-beam computed tomography study of canalis sinuosus and its accessory canals in a South African population.

Objectives: Canalis sinuosus (CS) is a clinically relevant structure in the anterior maxilla. The present study aimed to determine the prevalence and distribution of CS and its accessory canals (ACs) in the South African population and describe its anatomical variations.

Methods: In total, 500 cone-beam computed tomography (CBCT) scans of the anterior maxilla were assessed for prevalence, sidedness, diameter, and distribution of CS.

Clinicoradiologic features of ameloblastomas: A single-centre study of 155 cases.

Background: The purpose of the current study was to report on the clinical presentation and radiologic features of 155 cases of ameloblastoma (AB), representing a detailed, large, single-centre radiologic study.

Methods: Histologically confirmed cases were reviewed over 11 years. Demographic and clinical data were retrieved from the patient's records.

Fibrodysplasia ossificans progressiva.

Key Clinical Message: Fibrodysplasia ossificans progressiva is a progressively debilitating condition associated with significant morbidity caused by heterotopic ossification. Recognition of the early signs of hallux valgus and painful soft tissue nodules can assist in the early diagnosis of this condition. Periodic radiographic examination is mandatory to monitor the disease progression.

Clinicopathological Features of Metastasis to the Oral and Maxillofacial Region-Multicenter Study.

Background: This study aimed to investigate the clinicopathological features of metastases in the oral and maxillofacial regions.

Methods: In this retrospective study, biopsy records were obtained from referral centers for oral and maxillofacial diagnosis in Brazil, Guatemala, Mexico, and South Africa.

Results: A total of 120 cases were evaluated.

The radiologic progression of ameloblastomas.

Background: In developing countries, many diagnosed cases of ameloblastoma (AB) have a significant delay in receiving treatment because of patient factors and healthcare facility constraints.

Objectives: The radiologic progression of ABs with delayed treatment was analysed using panoramic radiographs and cone-beam computed tomography imaging.

Method: Histopathologically confirmed cases of AB with follow-up radiographs indicating no treatment were retrospectively reviewed over a study period of 10 years.

Resolution of Apical Periodontitis-induced Mental Nerve Paresthesia Through Nonsurgical Endodontic Retreatment: A Case Report.

Paresthesia is a potential consequence of unsuccessful root canal treatment. Persistent infection resulting in apical periodontitis may enlarge sufficiently to involve the mental neurovascular bundle. The case presented in this report was referred for endodontic evaluation with a chief complaint of discomfort on mastication and persistent numbness of the lower left lip.

Radiological aspects of lymphomas and leukaemias affecting the jaws: A systematic review.

Background: This systematic review aimed to investigate the radiological features of lymphomas and leukaemias affecting the jaws.

Methods: A systematic literature review was conducted using the electronic databases of PubMed, Web of Science and Scopus. Articles that contained sufficient radiographic examinations (periapical, panoramic or computed tomography images) for individual cases were included.

Keratoameloblastoma: A Report of Seven New Cases and Review of Literature.

Background: Keratoameloblastoma (KA) is an uncommon and controversial variant of ameloblastoma exhibiting central keratinisation. Due to their rarity, there is limited information in the literature on their clinical, radiologic and histologic features. This study adds seven additional cases of KA to the literature, and reviews the current published literature on this rare entity.

Clinicoradiological spectrum of primary aneurysmal bone cysts of the maxillofacial region: A series of 31 cases.

Objectives: The aim of the current study was to analyse the demographic, clinical and radiological features of primary aneurysmal bone cysts (ABCs) involving the maxillofacial region.

Methods: Histologically confirmed cases affecting the maxillofacial region were retrospectively reviewed over a 21-year period (2000-2021). Cases were collected from the archives of five Oral Pathology laboratories from three countries: South Africa, Guatemala and Brazil.
