A heterogeneity in the anatomy-based HNC nomenclature has resulted in underestimation of its incidence and significance worldwide. METHOD: The global cancer statistics database (GLOBOCAN) was used to evaluate the combined data of cancer incidence in two subsets: a.) excluding HNC and b.) including oesophageal cancers (Upper Aerodigestive Tract Cancer: UADTC). Combined age standardized incidence rates (ASIR) of HNC and UADTC were analyzed using both regional and individual country-derived data RESULT: Frequency ranking of HNC in Africa increases dramatically when cancers from contiguous HN regions are evaluated, compared with considering oral cancer data alone UADTC and HNC ranked second and third in Africa, respectively. Similar trends were observed by global development index evaluation. CONCLUSION: With the exclusion of a few urban regions, the diagnostic and treatment opportunities for HN/UADT cancers in sub-Saharan Africa are dismal Effective education and research efforts by local and international (non-) governmental agencies are urgently required to reduce the associated morbidities. <![CDATA[<b>The relationship between oral candidiasis and micronutrient deficiency amongst adult tuberculosis patients in Alexandra, Johannesburg</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018000800004&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Tuberculosis (TB), a major public health problem worldwide, is associated with micronutrient deficiency and wasting, and co-infections could worsen the condition AIM: To investigate the relationship between micronutrient deficiency and oral candidiasis in adult TB patients METHODS: A cross-sectional study among 88 TB adult patients in Alexandra, Johannesburg. Patients underwent a complete oral examination to establish the prevalence of candidiasis and blood was collected for the assessment of micronu-trient levels RESULTS: The mean age of participants was 36.66 years of age, the majority being female (60.23%) and HIV positive (69.30%). The prevalence of oral candidiasis was 39.77% with pseudomembranous being most common (48.00%). In those with micronutrient deficiencies, oral candidiasis was prevalent in 40% patients with Zinc deficiency, 25.00% with Vitamin A deficiency, 32.00% with Albumin deficiency, 33.00% with Selenium deficiency, 31.00% with Iron deficiency and in 36.00% with Vitamin D deficiency CONCLUSION: There was a significant association between the presence of oral candidiasis in TB/HIV co-infected patients and Zinc, Vitamin A and Vitamin D- deficiencies, but not in the TB only group <![CDATA[<b>Dental management of patients with inherited bleeding disorders: a retrospective study</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018000800005&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Minor invasive procedures can precipitate a prolonged bleeding episode in patients who have inherited bleeding disorders (IBD). Protocols have been established to minimize this postoperative bleeding, and the management of dental procedures performed on patients with IBD have been reviewed internationally. This paper undertakes a review of the topic and is probably the first of this nature in South Africa AIM AND STUDY DESIGN: This retrospective study reviewed dental procedures performed over a 16-year period on patients with IBD at the Charlotte Maxeke Johannesburg Academic Hospital (CMJAH), and compared those treatment approaches with published international guidelines. METHODS: The data were extracted from the files of patients seen at the Haemophilia Comprehensive Care Centre (HCCC) and from the Wits Oral Health Centre (WOHC) database at CMJAH RESULTS: Dental extractions accounted for 58% of dental procedures performed.Local haemostatic agents were used in 42% of the study population Postoperative bleeding was observed in three subjects, and the management of these correlated with the published guidelines. CONCLUSION: In this single centre review, bleeding following dental procedures was infrequent. The recommended improvements include greater use of preventive and supportive dental procedures; and administration of local haemostatic agents in invasive procedures <![CDATA[<b>Root canal treatment in mandibular canines with two roots: a review of the literature and a report of three cases</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018000800006&lng=pt&nrm=iso&tlng=pt Endodontic treatment may sometimes fail because the morphological features of the tooth can adversely affect the treatment procedures. Mandibular canines can present with complex internal anatomy and many investigators have reported associated anatomical variations. This paper describes three clinical case reports of mandibular canines, each with two roots and two canals. In addition, the prevalence, aetiology, root morphology and the clinical and radiographic diagnoses for mandibular canines that present with this anatomical variation will be discussed. <![CDATA[<b>Oral health status of sentenced offenders in KwaZulu-Natal province</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018000800007&lng=pt&nrm=iso&tlng=pt OBJECTIVE: To assess the oral health status, knowledge, attitude and practice of sentenced offenders in KwaZulu-Natal correctional centres METHODS: Simple random sampling selected 373 offenders from nine correctional centres in KwaZulu-Natal, South Africa. Data were collected using a closed-ended structured questionnaire, collated and analyzed using the Statistical Package for Social Sciences (SPSS) version 24 RESULTS: One hundred and sixty-one (43.2%) were aged 18-29, 144 (38.6%) in age group 30-39, 52 (13.9%) in group 40-49 and 16 (4.3%) were older than 50 years. Over two thirds of the study participants (72.7%) reported brushing teeth twice daily Oral health was perceived as poor by 292 (78.3%) offenders. Common self-reported dental problems were caries, bleeding gums, loose teeth and sensitive teeth. Cigarette smoking was prevalent and relatively high among offenders older than 50 years. CONCLUSION: Special attention is required from the Department of Correctional Services and the public oral health sector to meet the basic oral health needs of this population. A preventive-oriented oral health care system can synergistically complement other existing services offered in correctional facilities such as the smoking cessation programme. The prevalence of oral diseases of this vulnerable population can be drastically reduced <![CDATA[<b>Antibiotic prescribing practices of dentists at Medunsa Oral Health Centre</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018000800008&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Inappropriate prescribing and excessive use of broad spectrum antibiotics are reported to be leading contributors to the development of antimicrobial resistance worldwide AIMS AND OBJECTIVES: To examine the antibiotic prescribing practices of dentists in Medunsa Oral Health Centre. The range of conditions for which antibiotics were prescribed was identified and the characteristics of antibiotic prescribing were described. The prescription practices were investigated for concurrence with available evidence. DESIGN: A retrospective, cross-sectional descriptive study in which existing medical records were reviewed METHODS: Medical records of patients who received medication from the dispensary during March 2017 were reviewed Data in the health history questionnaire and data related to demographic characteristics, condition(s) diagnosed, procedure carried out and medication prescribed were extracted. Information from recent independent reviews and individual studies was reviewed to assess the alignment of prescribing practice with available evidence. References in retrieved review articles were used to identify additional studies. RESULTS: Healthy patients comprised 74.6% of the study participants. Perioperative prophylactic antibiotics for dental extractions accounted for 59.1% of the prescriptions.
