The genus Mycoplasma and L-form bacteria are both members of this group. The aim of this study was to search cell-wall-deficient bacteria in periodontal biofilm and link their presence to periodontal disease. Eighty-nine individuals were recruited and divided into three groups: periodontally healthy individuals, individuals with chronic periodontitis, and those with aggressive periodontitis. The presence of cell-wall-deficient bacteria was detected in freshly collected biofilm by light microscopy, transmission electron microscopy (TEM) with and without electron microscopy in situ hybridization, atomic force microscopy and DNA stain (Hoechst). A new dichotomic index of classification for prevalence and morphologic variants was developed to classify cell-wall-deficient bacteria in periodontal biofilm. Cell-wall-deficient bacteria were found in periodontal biofilm and classified into Protoplastic, Everted, Filament and Intracellular forms, the last one mainly associated with aggressive periodontitis. We also assessed the prevalence of periodontopathic bacteria by means of polymerase chain-reaction (PCR) and found no clear, statistically significant, correlation among periodontal pathogens tested (except T. denticola) that allowed individuals with chronic periodontitis to be distinguished from those with aggressive periodontitis. Association between cell-wall-deficient bacteria and periodontal condition was: periodontally healthy, 3.3% (1/30); individuals with chronic periodontitis, 30.6% (11/36); and those with aggressive periodontitis, 100% (23/23).

Among the various organs involved, the skin is one of the\u0000most frequent site, sometimes being the first manifestation of the disease. The frequency of oral mucosal\u0000manifestations is variable, between 9 to 45% of SLE and 3 to 20% of Chronic Cutaneous Lupus\u0000Erythematosus. Oral mucosal manifestation of LE can present themselves in different ways and their\u0000description is varied in different studies. Oral Lupus Erythematosus is histopathologically characterized as\u0000an interface mucositis with hyperkeratosis, alternating epithelial hyperplasia with atrophy, changes in\u0000epithelial maturation, vacuolization of the basal layer, thickening of the basement membrane by Schiff's\u0000periodic acid staining and superficial and deep lymph-histiocytic infiltrate in the lamina propria, which can\u0000show focal, interstitial, perivascular location or in a tight epithelial band.

Methodology: The flow was evaluated based on ISO 6876/2012 standard (mm) and in area (mm2 ). For assessment of filling ability and apical extrusion of the sealers, curved artificial canals were prepared up to size 25.06, and filled with the sealers by the single cone technique. The samples were scanned in microcomputed tomography (SkyScan 1272. Bruker, Belgium) after preparation and after filling of the root canals. The percentage of voids throughout the entire extension of the root canals and in the apical third, besides the volume of apical extrusion of each sealer were calculated. Data were statistically analyzed using ANOVA/Tukey tests (α = 0.05). Results: Bio-C Sealer showed the highest flow and NeoMTA Plus had the lowest value (p < 0.05). Bio-C Sealer had lower percentage of total voids than NeoMTA Plus (p < 0.05). AH Plus had greater percentage of voids in the apical third than Bio-C Sealer and Sealer Plus BC (p < 0.05). Bio-C Sealer showed higher volume of extrusion (p < 0.05) than AH Plus and NeoMTA Plus. Conclusion: Bio-C Sealer and Sealer Plus BC had greater flow and proper filling ability in the apical third.

Failure to keep a denture clean can lead to staining\u0000from foods, along with subsequent colonisation of the denture and associated mucosa by microorganisms,\u0000particularly Candida albicans. This colonisation can potentially lead to chronic erythematous candidosis\u0000and other oral infections. This study investigated the association between staining of denture acrylics by\u0000different food types and subsequent C. albicans colonisation.\u0000Materials and Methods: Chemically polymerised acrylic specimens were produced and stained for 14 days\u0000with six different combinations of food stains. The level of acrylic staining was determined\u0000spectrophotometrically. Specimens were then incubated in Sabouraud-dextrose broth (SAB) or SAB\u0000inoculated with Candida albicans. Confocal laser scanning microscopy coupled with propidium iodide\u0000staining of C. albicans was used to determine the extent of C. albicans colonisation to these acrylics. Results\u0000analysed descriptively and by one-way analysis of variance (ANOVA), one sample student t-test, and\u0000Dunnett’s test.\u0000Results: Acrylics in Group 4 (stained with spices, tomato puree, acai berry juice and sunflower oil)\u0000exhibited highest staining but had low C. albicans colonisation. Highest C. albicans colonisation occurred\u0000with Group 5 (sunflower oil) stained acrylics. The unstained control acrylic group had lowest colonisation.\u0000Conclusion: This study demonstrated that staining acrylics with certain foods promoted C. albicans\u0000colonisation, but this was not associated with level of visual staining. Further research is required to\u0000determine the precise mechanism(s) by which residual food stains promote candidal colonisation on denture\u0000acrylics. This knowledge may then be used by dental professionals to advise patients on improving denture\u0000hygiene to improve not only denture aesthetics but also minimise Candida biofilms.","PeriodicalId":72781,"journal":{"name":"Dental Oral Biology and Craniofacial Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69831804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On inspection of the oral cavity, the mucous\u0000membranes appeared unscathed. The previously extracted aleveolus of 1.6 was evident.
