Validation of ATP bioluminescence as a tool to assess antimicrobial effects of mouthrinses in an in vitro subgingival-biofilm model
Objectives. The aim of this investigation was to evaluate whether the adenosine triphosphate (ATP) bioluminescence method is an appropriate tool to assess the efficacy of antiseptic mouthrinses in terms of quantitative reductions of total viable microbial counts in mixed biofilm populations in vitro. Study Design. Three mouthrinses, containing respectively, chlorhexidine and cetylpyridinium chloride (CHX/CPC), essential oils (EO) and amine fluoride/stannous fluoride (AFSF), as well as Phosphate Buffered Saline (PBS) used as control, were tested in an in vitro static biofilm model by ATP bioluminescence and compared to culture method. Biofilms were grown on saliva-coated hydroxyapatite disks…
Comparison of the detection of periodontal pathogens in bacteraemia after tooth brushing by culture and molecular techniques
Background: The prevalence and amounts of periodontal pathogens detected in bacteraemia samples after tooth brushing-induced by means of four diagnostic technique, three based on culture and one in a molecular-based technique, have been compared in this study. Material and Methods: Blood samples were collected from thirty-six subjects with different periodontal status (17 were healthy, 10 with gingivitis and 9 with periodontitis) at baseline and 2 minutes after tooth brushing. Each sample was analyzed by three culture-based methods [direct anaerobic culturing (DAC), hemo-culture (BACTEC), and lysis-centrifugation (LC)] and one molecular-based technique [quantitative polymerase chain reactio…
Assessing EPAP lexical features: A corpus-based study
The features of specialised languages have been extensively described by scholars in the literature. Amongst them, Enrique Alcaraz’s work stands out as an exhaustive and comprehensive description of EPAP at all linguistic levels: lexical, syntactic, semantic and pragmatic. This research aims to provide a bottom-up assessment of his description on a lexical level through the implementation of corpus-based techniques on two specialised corpora of legal and telecommunications English. The results support Alcaraz’s portrayal as regards term usage, the relevance of sub-technical vocabulary, the peculiarities of Latin single and multi word terms in legal English and the significant presence and u…
