A total of 120 questionnaires were distributed to oral health workers located in private and public dental settings in eThekwini district. One hundred (n=100) completed questionnaires were retrieved, yielding a response rate of 83%RESULTS: The majority of participants (82%) reported that HIV testing and counselling did not occur in their workplace. Participants (87%) also indicated to have not been trained to perform HIV testing Sixty-six participants (66%) reported willingness to implement HIV testing in their respective dental workplace. Less than half of the study population (41%) were "unsure" regarding the accuracy of rapid HIV testing.CONCLUSION: Participants reported inadequate knowledge and practice of VCT. Participants had positive attitudes towards VCT implementation in the dental setting, provided that adequate training and support was available from the KwaZulu-Natal Department of Health <![CDATA[<b>Orthodontic repositioning of traumatically intruded permanent incisors - A report of three cases</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162021000100005&lng=en&nrm=iso&tlng=en Intrusive luxation of permanent teeth is one of the most serious traumatic dental injuries involving damage to the gingival tissue, periodontal ligament, cementum, bone and to the neurovascular supply of the pulp. In addition to disruption of normal tooth development and eruption, it can also lead to pulpal necrosis, root resorption and marginal bone loss. Based on the extent/severity, intrusion maybe classified into mild (<3mm), moderate (3-6mm) and severe (&gt;6 mm). Available techniques for managing intrusive luxation include a wait-and-watch approach to allow for spontaneous re-eruption, orthodontic traction and surgical repositioning. The type of treatment approach employed depends upon the stage of root development, severity of intrusive luxation and the presence or absence of alveolar fractures. It is difficult to predict reliable outcomes with these approaches, since the presence of variables such as the severity of intrusion, associated crown/root fracture, stage of root development and presence of alveolar fractures may alter the prognosis. The present article presents a series of three cases with intrusive luxation of permanent incisors successfully treated using an interdisciplinary approach involving orthodontic traction along with endodontic rehabilitation. <![CDATA[<b>A comparison of root canal transportation and centering ability between WaveOne® Gold and Protaper Next® files, using micro-computed tomography</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162021000100006&lng=en&nrm=iso&tlng=en AIM: This study compared the transportation and centering ability of ProTaper Next (PTN) and WaveOne Gold (WOG) files in curved permanent teeth using micro-computed tomography (μCΤMETHODOLOGY: Twenty-four molar teeth with curved roots were divided randomly into two equal groups. The root canals of one group was prepared using PTN files, and the other using WOG files. Pre-instrumentation and post-instrumentation imaging were taken for all the teeth. The dentine thickness of the pre-and the post-instrumentation cross sections was measured at eight different points at three levels: 3, 5 and 7mm from the apex, by two dentists using image analysis software. The data were analysed using one-way ANOVA, at a 5% significance levelRESULTS: The transportation in both groups was within the range accepted in the literature. The WOG file exhibited significantly less root canal transportation compared with the PTN file (p=0.001). The WOG file showed a significantly (p<0.001) higher mean centering ratio of 0.4286 when compared to that of PTN at 0.2448CONCLUSIONS: Using a novel technique to measure canal transportation, this study found that the WOG and PTN systems were both suitable for preparation of curved molar root canals, but the WOG showed significantly less canal transportation and better centering ability than the PTN system <![CDATA[<b>Factors influencing apical debris extrusion during endodontic treatment - A review of the literature</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162021000100007&lng=en&nrm=iso&tlng=en AIM: This study compared the transportation and centering ability of ProTaper Next (PTN) and WaveOne Gold (WOG) files in curved permanent teeth using micro-computed tomography (μCΤMETHODOLOGY: Twenty-four molar teeth with curved roots were divided randomly into two equal groups.

As a consequence the South African government imposed hard lockdown measures (level 3) as a means to curb the pandemic. Governments around the world are scrambling to obtain and roll-out Covid-19 vaccination programs to save lives and livelihoods. Most developed countries have initiated inoculations, amid widespread misinformation and hesitancy. Literature indicate that healthcare professionals (HCPs) are generally complacent and hesitant about vaccination. The COVID-19 uptake is likely to be suboptimal among HCPs and the general populations. The voluntary immunization program will commence in February 2021, and the Healthcare professionals will be among the first to be vaccinated. It remains to be seen if this cohort will achieve the desired vaccinations rates. Failure for this influential group to vaccinate could derail the program and lead to failure to achieve herd immunity. In the face of emerging vaccine hesitancy among HCPs, should oral health professionals be compelled to vaccinate? Will any refusal by OHPs to be immunized be morally justified? Oral health professionals in this context of this paper, represent all oral health professionals involved in the management dental patients. No singular ethical framework is held as sufficient to resolve these questions. This paper interrogates aspect of clinical ethics, including the Hippocratic Oath, principilism, public health ethics (Utilitarianism) and Kantian deontology, to tackle the questions raised. We conclude that OHPs have a moral duty to be vaccinated against Covid-19.
