AIMS AND OBJECTIVES: The aims and objectives of this qualitative study were to investigate the perceptions of parents regarding their influence of the unhealthy behaviour of South African adolescents in their excessive consumption of free sugars. DESIGN: The study design was qualitative exploratory and the research strategy, inductive, deductive and abductive. METHODS: Data were collected from five focus group interviews using the non-probability purposive theoretical sampling method and the data were analysed using the grounded theory approach. RESULTS: The parents contended that while natural sugars are acceptable, refined (free) sugars cause dental caries and gum diseases. CONCLUSION: Parents attributed the excessive consumption of free sugars among adolescents to their availability both at home and in the stores as well as their affordability. The present study recommends that babies be weaned off exclusive breastfeeding after six months with meals not sweeter than maternal breast milk and parents and schools should provide enabling environments that do not encourage excessive consumption of free sugars. <![CDATA[<b>Dental status of children receiving school oral health services in Tshwane</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000400004&lng=pt&nrm=iso&tlng=pt BACKGROUND AND PURPOSE: School health services and baseline oral health information are central to monitoring the progress of ongoing reforms, addressing areas requiring improvement and revitalization of South African primary health care. The study described the dental status of learners receiving oral health services in Tshwane, and assessed the influence of factors such as age, gender, location, and services received. METHODS: A cross-sectional analytical study design with a multistage sampling technique was employed to randomly select ten schools. Oral health examinations were conducted on all learners in two selected grades in each school RESULTS: There were 736 participants, ages 6 to 16 years, 50.9% were girls. Dental caries prevalence in the permanent dentition was 25.9% and in the primary dentition, 30.2%. Mean DMFT/dmft scores were [(0.90; SD:1.7; SiC :2.7); (1.2;SD:2.3; SiC:3.7)] respectively PUFA/pufa prevalence mostly affected the primary dentition (pufa 5,2% vs PUFA 2.2%). The unmet treatment need (UTN) was 89.6% and associated factors included gender, location and type of services received. CONCLUSION: The prevalence of dental caries was relatively low in comparison with similar South African studies, but untreated disease levels were high. Most affected were females, primary school learners, urban learners and those not participating in a supervised tooth brushing programme <![CDATA[<b>Oral health-related knowledge, attitudes and practices of adult patients in Mangaung Metropolitan Municipality, South Africa</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000400005&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Planning and implementation of oral health education is of more value when oral health-related knowledge, attitudes and practices (KAP) are known AIM: To assess and describe oral health-related KAP of adult patients in the Mangaung Metropolitan Municipality using the theory of planned behaviour METHODS: A quantitative descriptive design was used and data were collected from a sample of 207 adult oral health patients using a questionnaire based on the Theory of Planned Behaviour (TPB RESULTS: Positive responses by participants towards oral-related KAP were regarded as strengthening oral health-related practices. Oral health-related knowledge as reflected by participants' behavioural beliefs (93.7%), normative beliefs (81.1%), subjective norms (70%) and perceived behavioural control (71.9%) strengthened oral health behaviours positively. Participants' control beliefs did not strengthen oral health practices. Participants' attitudes (62.3%),intention (98.5%), actual behavioural control (99%) and behaviour (95.1%) strengthened oral health-related practices Adult patients generally portrayed behavioural beliefs, normative beliefs, subjective norms and perceived behavioural control that strengthened oral health behaviours positively. CONCLUSIONS: Understanding oral health-related KAP of adult patients would assist role players in the health sector to plan evidence based oral health education. Healthcare workers should be sensitive to the KAP of adult patients receiving oral health-related care <![CDATA[<b>Root canal preparation: A literature review and clinical case reports of available materials and techniques</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000400006&lng=pt&nrm=iso&tlng=pt Mechanical enlargement and shaping of complex endodontic root canal systems to facilitate disinfection remain the main foci of endodontic treatment. A large variety of root canal shaping and preparation systems with different design features and advantages are available to the clinician. Although there are many studies in the literature comparing these different systems, the aim of this paper is to provide the clinician with an overview of some of the available systems as well as their clinical applications. <![CDATA[<b>Cemento-osseous dysplasia: a diagnostic challenge</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000400007&lng=pt&nrm=iso&tlng=pt Cemento-osseous dysplasia is the most common fibro-osseous lesion affecting the jaw bones. Due to the potential risk of introducing an infection, biopsy of an asymptomatic lesion is contra-indicated and it is therefore mandatory to establish an accurate diagnosis only on clinical and radiological information. In order to achieve this, a thorough knowledge of the clinical manifestations of cemento-osseous dysplasia together with the pertinent radiological features is required. This paper is aimed at providing oral health practitioners with the diagnostic features and clinical differential diagnosis of the spectrum of lesions categorised as cemento-osseous dysplasia. <![CDATA[<b>What's new for the clinician: excerpts from and summaries of recently published papers</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000400008&lng=pt&nrm=iso&tlng=pt Cemento-osseous dysplasia is the most common fibro-osseous lesion affecting the jaw bones.
