Mesiobuccal canals of 50 mandibular first molars were used. Teeth were randomly divided into two preparation groups. Results were analysed using a one-way analysis of variance (ANOVA). Apically, ProGlider/ProTaper Next X2 demonstrated better centering ratio values and lower transportation values compared to WaveOne Gold Glider/Primary WaveOne Gold (p<.05). No differences were found in the mean combined centering ratios and transportation values between groups (p&gt;.05). No statistically significant differences between the canal preparation times were found (p<.06). The combination of ProGlider /ProTaper Next X2 yields better results for transportation and centering ability apically compared to WaveOne Gold Glider in combination with Primary Wave-One Gold. <![CDATA[<b>Sterilisation and single-use of endodontic files - a short report</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162020000400005&lng=en&nrm=iso&tlng=en INTRODUCTION: In many countries, endodontic files continue to be sterilised and reused in multiple clinical cases as the alternative of single-use of these instruments is avoided due to financial reasons. METHODS: A survey was performed including South African general dental practitioners and specialist prosthodontists to determine the current endodontic file sterilisation methods in place and the adoption rate of single-use protocols of both hand and engine-driven instruments. RESULTS: The majority of respondents (76.6%, n=141/184) indicated autoclaving endodontic files prior to reuse. Almost a quarter of the respondents (23.4%, (n=43/184) used only cold sterilisation. Some respondents (2,8%, n=5/181) indicated not sterilising their files at all. A low number of respondents had adopted the single-use of endodontic hand files (10.9%, n=20/184). Engine-driven files were used only once and discarded by 18.5% (n=34/184) of respondents. CONCLUSION: It appears that, at times, acceptable infection prevention and control practices regarding the sterilisation these instruments are not necessarily being adhered to. The adoption of single-use protocols of endodontic files in a South African dental setting is higher than previously reported. <![CDATA[<b>The microbiology of head and neck space infections at the Maxillofacial Clinic at Livingstone Hospital</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162020000400006&lng=en&nrm=iso&tlng=en INTRODUCTION: Head and neck space infections remain one of the most commonly encountered conditions at Maxillofacial clinics countrywide. Patients admitted with these infections tend to have prolonged hospital stays and often require intensive care support. This places financial and logistic constraints on our health care system. There are also growing concerns, worldwide, regarding antibiotic resistance AIMS AND OBJECTIVES: To determine the microbial spectrum of head and neck space infections in patients admitted to the Maxillo-Facial clinic at Livingstone Hospital in the Eastern Cape over a period of 5 years. METHODS: Demographic, clinical and laboratory data was retrieved from the medical records of 140 patients presenting with head and neck space infections RESULTS: Most patients were males aged 21-40 years. The most common cause of head and neck infections was non-odontogenic. The submandibular space was the most commonly implicated. Gram positive facultative anaerobes were most commonly identified. Bacteroides species and Staphylococcus aureus displayed sensitivity to clindamycin and amoxicillin with clavu-lanic acid. Viridans streptococci were sensitive to both penicillin and clindamycin CONCLUSION: Bacteroides species were the most commonly isolated bacteria, followed by Viridans streptococci and Staphy-lococcus aureus. <![CDATA[<b>Student perceptions of clinical experiences in endodontic access cavity preparations</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162020000400007&lng=en&nrm=iso&tlng=en OBJECTIVES: The aim of this study was to gain understanding into the perceptions of undergraduate dental students regarding their levels of competence and confidence when preparing endodontic access cavities MATERIALS AND METHOD: Anonymous survey forms were given to 100 undergraduate dental students at Sefako Makgatho Health Sciences University, School of Oral Health Sciences. Students were asked to indicate their self-confidence level by using a 5-point Likert scale as 'not confident', 'manageable', 'comfortable and confident',' extremely confident' and 'never done it'. RESULTS: The response rate was 75 % out of 100 students. The majority of the participants (88%) indicated that they would perform endodontic access cavity preparation with ease on anterior teeth and the lowest (43%) confidence levels was indicated on multi-rooted posterior teeth <![CDATA[<b>Focal dermal hypoplasia - a radiographic case report</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162020000400008&lng=en&nrm=iso&tlng=en Focal dermal hypoplasia (FDH) is an unusual X-linked dominant disorder that affects ectoderm and mesoderm derived tissues with females affected in 90% of cases. A case report ofa12 year old female diagnosed with FDH is presented. The dental significance of these patients are multifactorial and dental management should be focused on prevention and regular monitory visits. Restoration of functionality should be addressed by a combination of orthodontic, basic restorative and pros-thodontic disciplines. Due to the multisystem involvement and the dental complexities of patients suffering from FDH a multidisciplinary approach is required for optimal patient care. <![CDATA[<b>Lichenoid Granulomatous Stomatitis - an oral medicine case book</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162020000400009&lng=en&nrm=iso&tlng=en Focal dermal hypoplasia (FDH) is an unusual X-linked dominant disorder that affects ectoderm and mesoderm derived tissues with females affected in 90% of cases.
