fa Biofilm of Candida albicans from oral cavity of an HIV-infected child: challenge on enamel microhardness بیماری های دهان Oral Medicine پژوهشي Research <p> <strong>Objective</strong></p><p>  The aim of this study was to analyze the effect of C. albicans on enamel microhardness in vitro. </p><p> <strong>Study Design</strong></p><p>  Candida albicans was isolated from the oral mucosa (M) and dentin carious lesion (D) of an HIV+ child. Three groups of 12 enamel blocks each were placed in Petri plates (yeast carbon base agar/1% bovine serum albumin): G1, exposed to biofilm formed by C. albicans from M G2, exposed to biofilm formed by C. albicans from D G3, no biofilm. Three enamel blocks from each group were removed on days 3, 5, 8, and 10 after biofilm formation to measure the cross-sectional Knoop microhardness (CSMH) of the enamel areas, exposed and not exposed to biofilm. <strong></strong></p><p> <strong>Results</strong> </p><p> CSMH decreased in G1 and G2: in G1 on day 5, and in G2 on day 3 (analysis of variance: P < .05 Mann-Whitney test: P < .05), with a similar mean percentage reduction for both groups. </p><p> <strong>Conclusions</strong></p><p>  Candida albicans can reduce enamel microhardness in vitro. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p> <a href="http://www.oooojournal.net/article/S2212-4403(12)01707-5/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1582&slc_lang=fa&sid=1 Senda Charone 10031947532846007324 10031947532846007324 No Department of Pediatric Dentistry and Orthodontics, School of Dentistry, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil Maristela Barbosa Portela 10031947532846007325 10031947532846007325 No Department of Clinics and Pediatric Dentistry, School of Dentistry, Universidade Federal Fluminense, Niterói, Brazil Madeleine Souza das Chagas 10031947532846007326 10031947532846007326 No Department of Pediatric Dentistry and Orthodontics, School of Dentistry, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil Rosangela Maria de Araújo Soares 10031947532846007327 10031947532846007327 No Department of Microbiology, Institute of Microbiology Professor Paulo de Góes, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil Gloria Fernanda Barbosa de Araújo Castro 10031947532846007328 10031947532846007328 Yes Department of Pediatric Dentistry and Orthodontics, School of Dentistry, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil
