These developments would be of clinical interest for dentists in endodontics, in which exciting areas of endodontic research are emerging. In roots having thin dentinal walls, there is a risk of fracture when mechanical preparation of the root canal is undertaken. The innovative option of regenerative endodontic procedures could prove to be an effective approach in these cases. This review is an attempt to update on the current trends. <![CDATA[<b>Microbial contamination of denture polishing equipment</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000300005&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Lathes and pumice slurry are commonly used without change or disinfection for polishing both new and old, repaired dentures PURPOSE: To identify and quantify any microorganisms harboured in these components in the laboratories of an academic teaching institution where the machines are in constant daily use. MATERIAL AND METHODS: Two machines were identified and labelled in each laboratory, one for exclusive use for new dentures and the other for dentures which had been exposed to any form of patient oral contact. Users were so informed. Samples were collected twice daily on alternate days over a period of one week and tested for the presence and type of microorganisms, and whether the levels of contamination increased with usage. RESULTS: Pumice throughout was contaminated with a variety of bacteria, yeasts and moulds. notably Aspergillus, which will hover in the abundant aerosol during polishing. Cross-contamination can thus occur between dentures, posing danger to patients. Consultation between the dental staff and the Department of Medical Microbiology established a standardised disinfection protocol for the polishing wheels, machinery and pumice slurry. CONCLUSION: Prevention of cross contamination is crucial to avoid inadvertent but nevertheless culpable infection of denture-wearing patients, as well as for personal protection. <![CDATA[<b>Radiographic assessment of multiple pathoses and dental malocclusion: a case study</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000300006&lng=pt&nrm=iso&tlng=pt Odontomas are rare pathological abnormalities which may occur at any age. It is most unusual to observe an odontoma together with supernumerary teeth, more particularly if this is found in conjunction with an osteoma. This report emphasizes the underlying pathology of a case co-incidentally encountered in a 14 year old patient whose main complaint was of a painful 85 tooth. An incisional biopsy of the area revealed the presence of mineralized tooth-related tissue resembling a complex odontoma. In conjunction with the radiographic evidence, which confirmed the presence of complex and compound odontomas as well as a number of small osteomas, a provisional diagnosis of Gardner's syndrome was made. The syndrome is a rare autosomal disease that is difficult to treat. If a dentist suspects a patient may present with Gardner's syndrome, the patient should be referred immediately for further medical management. <![CDATA[<b>Chronic Suppurative Osteomyelitis of the Maxilla - rare case presentation</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000300007&lng=pt&nrm=iso&tlng=pt Chronic Suppurative Osteomyelitis of the maxilla is a relatively uncommon lesion with scarce information in the medical literature regarding its clinical/pathological status and treatment perspectives. We report a rare clinical case of a patient presenting with osteomyelitis of the maxilla with pus discharge. The review discusses the pathogenesis, clinical course, investigative procedures and treatment. The diagnosis in this patient was based on data assessed from a specialized imaging technique and from the histopathological findings. Timely medical and surgical therapy reduced the morbidity which may otherwise have occurred due to the significant complications associated with this chronic lesion. This interventional approach can thus be recommended as one of the novel treatments for osteomyelitis of the jaws with the prospect of significant clinical and radiological improvement, as was shown in the present case. <![CDATA[<b>Glide path preparation in Endodontics: case report and a literature review of available materials and techniques</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000300008&lng=pt&nrm=iso&tlng=pt Maintaining a smooth, reproducible, glide path when successive files are used is an important characteristic of proper root canal preparation. Glide path enlargement allows for safer, more effective canal shaping with increased prospects of successful treatment outcomes. Many authors have proposed that rotary nickel titanium (NiTi) instruments should not be used for canal preparation without prior glide path preparation. In this paper the authors discuss a review of the literature on some of these glide path techniques and illustrate the correct clinical application of some of these preparation techniques through clinical case studies. <![CDATA[<b>South African toothpaste pot lids</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000300009&lng=pt&nrm=iso&tlng=pt Maintaining a smooth, reproducible, glide path when successive files are used is an important characteristic of proper root canal preparation.
