Even though several clinical reports have documented the use of L-PRF, controversy still exists with regards to many aspects of this biomaterial. Diverse publications report the use of non-standardised methods to prepare L-PRF, resulting in variable clinical results. The impact of the type of centrifuge, as well as of the growth factor release kinetics, have recently been studied and have yielded new insights into the structure and function of L-PRF. The presence of bone morphogenetic proteins as well as stem cells has also been documented. In this report we analyse various factors affecting L-PRF preparation and its constituents and highlight some of the controversies surrounding the biomaterial. <![CDATA[<b><i>In vitro</i> antimicrobial comparison of three commercially available chlorhexidine-based oral rinses</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162016000700005&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Commercially available chlorhexidine (CHX) formulations differ in their CHX concentrations (0.2% and 0.12%) as well as in various additives including alcohol, antimicrobials such as cetylpyridinium chloride and anti-discolouration chemicals such as ascorbic acid and sodium metabisulphite. AIMS AND OBJECTIVES: To compare in vitro the antimicrobial efficacies of three different CHX preparations (Corsodyl®, Curasept® and GUM® Paroex®) using 0.2% and 0.12% CHX concentrations as controls. METHODS: A disk diffusion test was performed using pure cultures of the organisms Streptococcus mutans and Candida albicans, and mixed cultures (facultative and strict anaerobes) prepared from oral rinse samples of 14 study participants. The means and standard deviations of the diameters of inhibition zones were calculated. RESULTS: A statistically significant difference (p value = 0.0001) was found only in Candida albicans cultures between the mean inhibition zones of the CHX preparation disks. Pure CHX preparations and Corsodyl® showed higher antifungal efficacy than Curasept® and GUM® Paroex. CONCLUSION: Both CHX preparations (0.12% and 0.2%) and the 0.2% CHX preparation containing alcohol (Corsodyl®) have more potent antifungal properties against C. albicans than alcohol-free 0.12% CHX preparations such as Curasept® and GUM® Paroex® <![CDATA[<b>Availability, indications for use and main ingredients of mouthwashes in six major supermarkets in Gauteng</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162016000700006&lng=pt&nrm=iso&tlng=pt Patients often ask oral health care practitioners to recommend the "best" mouthwash for their specific needs and desires. Considering the vast array of products available, the number of television, radio and printed media advertisements, and the promotional campaigns from dental representatives, selecting and recommending a single product can be daunting. As a result, advice and selection are often based on personal preferences, and may not identify a mouthwash most suitable for the specific needs of a particular patient. This study was undertaken to investigate the range, availability, advertised indications and ingredients of all the mouthwashes on offer in six large supermarket chains in Gauteng. After identifying all the available over-the-counter mouthwashes on sale, a descriptive cross sectional study was undertaken. The advertised indications for use, active ingredients, mode of action and cost of the collected samples were compared. The results may help clinicians have a better understanding of the range, nature and characteristics of a selection from each brand enabling a recommendation of the most suitable product to meet each individual need. <![CDATA[<b>Oral candidosis: an update on diagnosis, aetiopathogenesis and management</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162016000700007&lng=pt&nrm=iso&tlng=pt Candidosis is the most common oral opportunistic infection and can be caused by any member of the heterogeneous genus Candida. Diagnosis is based on clinical features and on microscopic identification of the candidal hyphae or pseudohyphae on a smear or in a biopsy specimen of the lesional tissue. Although candida in both commensal and pathogenic forms has similar immunogenic properties, commensal yeasts generate a state of immune tolerance while pathogenic hyphae or pseudohyphae provoke an immuno-inflammatory reaction. The first step in the treatment of oral candidosis is to moderate any local and systemic predisposing factors, and to prescribe a course of topical antifungal agent. Systemic antifungal treatment should be considered only if topical treatment has been unsuccessful or in cases of severe oral candidosis in debilitated or immuno-compromised subjects. In this paper, we briefly describe the clinical variants, the diagnosis and the management of oral candidosis, and discuss the commonly used pharmacotherapeutic agents. <![CDATA[<b>Statistical terms Part 2: Principles of research study design: Understanding the options, indications and limitations</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162016000700008&lng=pt&nrm=iso&tlng=pt Candidosis is the most common oral opportunistic infection and can be caused by any member of the heterogeneous genus Candida.
