Extensive Mandibular Odontogenic Keratocysts Associated with Basal Cell Nevus Syndrome Treated with Carnoy's Solution versus Marsupialization.

The inherent proliferative capacity of the cystic lining of odontogenic keratocysts and tendency to recur with enucleation led to more aggressive management being widely recommended. Larger lesions preclude the possibility of resection. A case is reported in which extensive odontogenic keratocysts involve almost the entire mandibular medulla of a patient with basal cell nevus syndrome, illustrating the importance of customising treatment to accommodate the clinical and radiographic presentation of individual cases.

A clinical evaluation of dry sockets at the Medunsa Oral Health Centre.

Dry sockets, or alveolar osteitis, is one of the most common postoperative complications following the extraction of teeth. For the patient this is often a very painful and distressing condition. Most dental practitioners will experience this complication at some or other stage of their career.

Tooth width predictions in a sample of Black South Africans.

Space analysis during the mixed dentition requires prediction of the mesiodistal widths of the unerupted permanent canines and premolars and prediction tables and equations may be used for this purpose. The Tanaka and Johnston prediction equations, which were derived from a North American White sample, is one example which is widely used. This prediction equation may be inapplicable to other race groups due to racial tooth size variability.

Facial profile perceptions in a group of South African blacks.

Introduction: Each society has its own general perceptions of facial aesthetics and one study show that there is significant agreement among populations regarding facial preferences. People of African decent generally have a bimaxillary protrusive profile which in some orthodontic circles is regarded as a malocclusion that should be treated.

Objectives: The purpose of the study was to evaluate Black South African student perceptions on the facial profile of Black South African subjects with bimaxillary protrusion.

Soft tissue profile analysis in a sample of South African Blacks with bimaxillary protrusion.

Introduction: Evaluation of facial proportions and shape is one of the most important steps in determining treatment options and outcomes for the orthodontist and maxillo-facial surgeon. Balancing the position of the lips in relation to the nose and chin has a direct relationship with the patient's aesthetic preference.

Objectives: The purpose of this study was to analyse the soft tissue profile preferences in a sample of South African Blacks and to establish a Profile Index for bimaxillary protrusion.

Coronal leakage of teeth root-filled with gutta-percha or Resilon root canal filling material.

This study compared the micro-leakage of a root canal filled with Resilon or gutta-percha (GP), utilizing either cold lateral condensation or System B. Four experimental groups were used. Group one was obturated with GP using cold lateral condensation, group two with GP using System B, group three with Resilon using cold lateral condensation, and group four with Resilon using System B.

Enamel dysplasia with odontogenic fibroma-like hamartomas: review of the literature and report of a case.

This article reports on a case presenting with a rare syndrome characterized by enamel dysplasia and multiple unerupted teeth with large solid fibrous pericoronal lesions manifesting with odontogenic fibroma-like features. Our case shows in addition to these findings an anterior open bite malocclusion and gingival overgrowths. These overgrowths exhibit the microscopic features of the multiple pericoronal odontogenic fibroma-like lesions that appear to be the hallmark of this syndrome.

An introductory report on a new cephalometric method: the Dawjee analysis.

A new method of lateral cephalometric analysis referred to as the Dawjee analysis is introduced. Landmarks, planes and angles are defined, and the technique is outlined. The Dawjee analysis is primarily focused on evaluating craniofacial structures in the vertical dimension and this introductory presentation demonstrates its application in both open and deep bite cases.

Herpes zoster post-herpetic neuralgia.

Post-herpetic neuralgia (PHN) is the most frequent complication of herpes zoster and often results in significant morbidity and a reduction in the patient's quality of life. The peripheral nerve injury that occurs during the acute phase of herpes zoster (HZ) leads to an abnormal tonic impulse discharge from primary nociceptive afferent neurons which induce slow temporal summation. This "wind-up" phenomenon is responsible for continuous partial depolarisation of second-order neurons with increased spontaneous impulse discharge and expanded receptive fields within the dorsal horn nociceptive neurons.

HIV/TB co-infection: literature review and report of multiple tuberculosis oral ulcers.

Human immunodeficiency virus/tuberculosis (HIV/TB) co-infected subjects demonstrate enhanced HIV replication and plasma viremia; CD4+ T-cell depletion; morbidity and mortality; and susceptibility to secondary bacterial and fungal infections compared to subjects solely infected with HIV. As the incidence of HIV/TB infection has been increasing, one would have expected to encounter oral lesions of tuberculosis more frequently. However, such oral lesions are uncommon.

A review of candida and periodontal disease in immunocompetent and HIV-infected subjects.

The role of candida in the aetiology and pathogenesis of periodontal diseases is unclear. In spite of the organism being present in subgingival biofilm samples and in gingival biopsy specimens taken from affected subjects, it has not been possible to demonstrate that it is an active agent in these cases. There is an increase in the prevalence of candida species in the oral cavities and specifically in the subgingival biofilm of HIV-seropositive patients.

Halitosis: a review.

Halitosis, or bad breath, is caused by mainly volatile sulfur compounds (VSC) as a result of bacterial breakdown of protein and can be quantitatively and qualitatively measured in the expired oral breath. In eight to ninety percent of cases, halitosis originates in the mouth due to inadequate plaque control, periodontal disease, dry mouth, faulty restorations, and in particular due to excessive bacterial growth on the posterior third of the dorsal surface of the tongue. In the remaining ten to twenty percent of cases, bad breath is caused by systemic disorders such as hepatic, pancreatic and nephritic insufficiencies, trimethylaminuria, upper and lower respiratory tract infection, medication and cases where gastric content may generate oral malodour.

Low-grade intraosseous osteosarcoma of the jaws.

Two cases of low-grade intraosseous osteosarcomas are reported, bringing the total number of such osteosarcomas in the jawbones documented in recent literature to six. Our first case involved the maxilla of a 69-year-old man and the second involved the mandible of an 18-year-old girl. In clinical and microscopic appearance, these neoplasms resemble benign proliferations in many respects.
