The size and prominent location of the lesion(s) in the oral cavity ensures early recognition. This paper aims to provide a comprehensive background of this rare lesion and discusses the presentation in a neonate diagnosed at 35 weeks on a routine ultrasound. Oral health practitioners should be aware that these lesions may cause dental developmental anomalies at the site where they occur. <![CDATA[<b>Radiopacities in soft tissue on dental radiographs: Diagnostic considerations</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162015000200004&lng=pt&nrm=iso&tlng=pt Radiopacities in soft tissue in the maxillofacial and oral region frequently manifest on panoramic radiographs in various locations and in several sizes and shapes. Accurate diagnosis is important as the finding may indicate serious disease states. This manuscript provides guidelines for the interpretation of soft tissue radiopacities seen on dental radiographs and recommends additional radiological views required to locate and diagnose the calcifications. <![CDATA[<b>A comparison of the efficacy of various disinfection protocols in endodontic treatment: An <i>in vitro </i>study</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162015000200005&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Disinfection is the main objective of root canal preparation and whilst irrigation is most commonly used, another method is Photo-activated Disinfection (PAD). AIMS AND OBJECTIVES: The aim of this in vitro study was to compare the efficacy of eradication of bacteria from root canals by six different disinfection protocols. METHODS: Root canals of 84 extracted human teeth were prepared to a standardised size and taper. The teeth were sterilised and then inoculated with E. faecalis. The teeth were randomly assigned to one of seven groups (n = 12), each of which underwent a different disinfection protocol. Dentine samples were plated onto BHI plates and incubated anaerobically. After five days, colony-forming units (cfu) were counted. The Pairwise Wilcoxon Rank Sum test and the Kruskal-Wallis test were used for statistical analysis of the data. RESULTS: The most effective disinfection protocol was: 3% NaOCl with 2% CHX, followed by 3% NaOCl with PAD, Chlor-XTRA and 2% CHX. The 3% NaOCl-protocol performed significantly better than PAD and distilled water. The PAD-protocol performed significantly better than distilled water. CONCLUSION: The most efficient protocol in eradicating E. faecalis from the root canals was 3% NaOCl followed by irrigation with 2% CHX. <![CDATA[<b>Effectiveness of pictorial sign boards for patient navigation in multidisciplinary Dental Facilities</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162015000200006&lng=pt&nrm=iso&tlng=pt OBJECTIVES: Evaluation of the effectiveness of pictorial sign (symbol) boards in the identification of clinics/departments and in directing traffic in dental schools and hospitals. METHODS: Sign Boards (PSB's) were designed to illustrate dental clinical disciplines. 260 subjects were briefly instructed in the roles of these disciplines. A first questionnaire required participants to match PSB's with departments, and to identify the best PSB. A second questionnaire asked participants to rate how appropriate was the depiction of each department and to comment on the importance of PSB's in a multidisciplinary dental set-up. RESULTS: The PSB of of Oral & Maxillofacial Surgery (100%) was rated the most easily recognised, followed by the PSB's of Orthodontics & Dentofacial Orthopedics (99.6%), Public Health Dentistry (99.6%) and Oral Medicine & Radiology (99.2%). Least identifiable were the PSB's of Conservative Dentistry & Endodontics (86.2%) and of Periodontology (85.8%). The PSB's were generally approved, that for Orthodontics & Dentofacial Orthopedics gaining the highest rating, while those for Conservative Dentistry & Endodontics and for Periodontology scored the least. 97.3%-99.2% of the subjects agreed that PSB's would be valuable in dental clinics/hospitals to facilitate patient navigation. CONCLUSION: Pictorial Sign Boards are indicated in dental facilities. <![CDATA[<b>Oral medicine case book 67: Oral manifestations of Evans syndrome: a presenting feature of HIV infection?</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162015000200007&lng=pt&nrm=iso&tlng=pt OBJECTIVES: Evaluation of the effectiveness of pictorial sign (symbol) boards in the identification of clinics/departments and in directing traffic in dental schools and hospitals.
