AIMS AND OBJECTIVES:The aims and objectives of the present study were to investigate parents' perception of their role in the prevention of the health compromising behaviour of inadequate consumption of fruit and vegetables among adolescents in South Africa. DESIGN: The study design was qualitative and exploratory and the research strategy used was inductive, deductive and abductive. METHODS: Using a guiding question schedule data were collected from Ave focus group interviews. A non-probability purposive theoretical sampling method was utilized and the sample size of 37 determined by theoretical saturation. Data analysis was performed using the grounded theory approach. RESULTS: The findings of the study suggest that children should be introduced to fruit and vegetables as early as possible. CONCLUSION: The study recommends that infants should be exposed to the taste of locally available fruit and vegetables followed by the gradual introduction of fruit and vegetables into their diet together with a variety of other nutrient-dense foods when solid foods are being introduced. http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162020000500005&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Cross infection in the dental clinical environment remains a low priority in conversations around oral health care despite the high risk of exposure to blood and airborne infections. AIM AND OBJECTIVES: The aim of this study was to determine the presence of selected pathogens after use of disinfectants on specific dental environmental surfaces at a public oral health facility in KwaZulu-Natal. METHODS: This was a cross-sectional descriptive case study with a non-experimental design. The dental clinical environment was divided into four zones and 9 dental units were systematically selected Swabs were collected from the 26 identified areas at specific time intervals (7.00, 9.00, 11.00, and 16.00) after the use of chlorine, ethanol (70% in water) and glutaral-dehyde (2%) as surface disinfectants. The collected swab samples were cultured in nutrient agar media for two days at 37°C. The colony forming units were then examined and characterized using the MALDI-TOF spectrometer. RESULTS: Out of the 312 samples taken, 262 (84%) were shown to be bacterial culture positive. The most contaminated areas in the dental environment were around the chair area (86.53%) and the area away from the chair (92%) Glutaraldehyde was found to be more effective than chlorine and ethanol. CONCLUSION: The study suggests an association between the frequency of cleaning, the type of disinfectant used and the bacterial microbial count on the specified dental environmental surfaces at the identified oral health facility. http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162020000500006&lng=pt&nrm=iso&tlng=pt BACKGROUND: Maxillofacial and oral surgeons (MFOS) are trained to manage hard and soft tissue conditions affecting the orofacial region. They, therefore, play an essential role in the health care of cleft lip/palate (CLP) and craniofacial deformities (CFD) patients The complex and lengthy nature of CLP and CFD management requires collaboration between different disciplines. Consequently, it becomes increasingly important that the academic education available to MFOS provides in-depth knowledge, multidisciplinary participation and adequate clinical exposure provided by field experts. OBJECTIVES: This study aimed to investigate the exposure and knowledge level of MFOS regarding the management of CLP and CFD. A second objective was to obtain an opinion from practising MFOS about the academic educational needs of those working with CLP and CFD METHOD: An online survey and telephone interviews (using a structured questionnaire) were used to investigate the level and scope of the MFOS academic education and to determine their academic needs RESULTS: The questionnaire was completed by 53 (of 121) of practising MFOS on the Medpages health care provider database, 64.8% of whom had more than 10 years of professional experience Of the respondents, 60% showed a good general knowledge of CLP and CFD. However, 66.5% acknowledged that they had received only limited clinical training and exposure, which prevented them from providing adequate services to CLP/CFD patients. Only 41% of the respondents offered primary and/or only secondary treatment for both CLP and CFD patients, and 53.8% of them had participated in multidisciplinary teams. All the respondents agreed on the need for a dedicated training programme(s) in CLP and CFD management, and the majority recommended a subspecialty training either by degree courses or clinical fellowship and /or certification. CONCLUSION: This study demonstrates that postgraduate academic training and clinical exposure are limited in the CLP and CFD fields. All the respondents agreed that an educational strategy to meet the needs of MFOS providing CLP and CFD care should be established. Participants suggested that part-time clinical and/or degree courses should be developed http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162020000500007&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Removable partial denture (RPD) designs may differ based on types of materials used. AIMS: The aim of the study was to investigate how a sample of non-metal clasp (NMC), acrylic and metal RPD designs complied with biomechanical design principles. METHODS: This cross-sectional study examined 60 clinical designs of NMC, acrylic and metal RPDs at 3 commercial dental laboratories in the Cape Town Metropole, at the stage when the dentures were ready for transport to dentists. Retention, indirect retention, support, soft tissue cover, and cross-arch design features were recorded and compared with "ideal" control designs developed by 2 experts in the specialty of prosthodontics. RESULTS: Fifty Ave % of the clinical designs had no rests, hence were mucosa supported. None of the NMC and only 35% of acrylic RPDs had some rests. A total of 35 clinical designs required indirect retention, but it was only provided in 14 (40%) of them. Eighty Ave % of acrylic RPDs had no clasps; metal RPDs had more clasps than required while NMC RPDs had slightly less clasps than required. Ratio teeth covered/replaced was most favourable for metal (0.91), followed by acrylic (1.83) and NMC (1.80) RPDs. Cross - arch stabilization was absent in 22% of clinical designs, all of them from the NMC group. CONCLUSION: Of the 3 types of RPDs, metal RPDs complied best with requirements in terms of tissue support (mostly tooth and mixed tooth/mucosa), retention, cross-arch stabilization and "open" design. Acrylic RPDs provided cross-arch stabilization but were lacking in all other aspects. Except for direct retention, NMC RPDs did not conform to any of the agreed biomechanical requirements for RPDs assessed in this study. http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162020000500008&lng=pt&nrm=iso&tlng=pt Amelogenesis imperfecta (AI) comprises a vast group of developmental alterations in the quantity and/or quality of enamel, unaffected by systemic disorders. In this case report we describe the typical clinical and radiographic features of AI with multiple impacted teeth and altered eruption pathways. Patients with AI benefit from early diagnosis and treatment to prevent tooth loss and loss of vertical dimension. Optimal management of these patients requires a multi-disciplinary approach and regular dental recall appointments. Therefore it is the oral health clinician's responsibility for the timeous identification of this condition. http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162020000500009&lng=pt&nrm=iso&tlng=pt Amelogenesis imperfecta (AI) comprises a vast group of developmental alterations in the quantity and/or quality of enamel, unaffected by systemic disorders.
