Biofilms on oral piercings may serve as a bacterial reservoir and lead to systemic bacteraemia or local transmission of periopathogenic microbiota.
The investigators hypothesize that there are microbiological differences in bacterial samples collected from tongue /or lip piercings made of different materials. The investigators also hypothesize that the piercings carry the same characteristic bacteria as found in the piercing channels and that independently the biofilm on the tongue/adjacent teeth is similar to the other study locations.
85 subjects with tongue and 85 subjects with lip piercing will participate. Periodontal clinical parameters, traumata of hard tissues, and characteristics of the stud are evaluated. Sterile piercings of four different materials will be randomly allocated to the study subjects. After two weeks, microbiologic samples are collected and are processed by checkerboard DNA-DNA hybridization methods.

To assure the uniform collection, handling, storage and transport of patient whole blood specimens and associated information to support validation of the T2 Bacteremia Assay.
The presence of bacteremia and sepsis in percent of critically ill patients and none at all, associated with different expression and faction of Toll-Like-Receptors (TLRs.
The purpose of this study is to assess the safety and efficacy of ceftobiprole versus a comparator in hospitalized patients with bacteremia.
This study examines the clinical outcomes and healthcare costs associated with gram negative bacteremia at Duke University Medical Center from 2002-2015.
In the US and Europe, bacteremia are ranked the 7th leading cause of death from all causes. E. coli is one of the main microorganism involved, responsible for 30% to 45% of bacteremia. In ...
Maintaining healthy teeth and soft oral tissue is important. Clinical research has shown manual toothbrushes with end-rounded filaments to cause significantly less gingival abrasions than those withou...
Streptococcus agalactiae or group B streptococcus (GBS) is a frequent pathogen in immunocompromised adults. The aim of this study was to determine the relative frequency, clinical presentation, antimi...
Background: In recent years, increasing numbers of adults and adolescents have opted to undergo tattoo and piercing procedures. Studies among adolescents with tattoo and piercing have usually explored...
Scientific evidence is not clear regarding the use of antimicrobial mouth rinse before dental extraction to reduce bacteremia. We tested the null hypothesis that there would be no difference in the in...
Bloodstream infections remain a major cause of morbidity and mortality. Gram-negative bacilli (GNB) bacteremia is typically transient and usually resolves rapidly after the initiation of appropriate a...
The presence of viable bacteria circulating in the blood. Fever, chills, tachycardia, and tachypnea are common acute manifestations of bacteremia. The majority of cases are seen in already hospitalized patients, most of whom have underlying diseases or procedures which render their bloodstreams susceptible to invasion.
The transport of materials through a cell. It includes the uptake of materials by the cell (ENDOCYTOSIS), the movement of those materials through the cell, and the subsequent secretion of those materials (EXOCYTOSIS).
The only species in the genus GARDNERELLA, and previously classed as Haemophilus vaginalis. This bacterium, also isolated from the female genital tract of healthy women, is implicated in the cause of bacterial vaginosis (VAGINOSIS, BACTERIAL). It occasionally causes postpartum bacteremia and bacteremia following a transurethral resection of the prostate.
Substances used to create an impression, or negative reproduction, of the teeth and dental arches. These materials include dental plasters and cements, metallic oxide pastes, silicone base materials, or elastomeric materials.
Materials placed inside a root canal for the purpose of obturating or sealing it. The materials may be gutta-percha, silver cones, paste mixtures, or other substances. (Dorland, 28th ed, p631 & Boucher's Clinical Dental Terminology, 4th ed, p187)
Dentistry is the study, management and treatment of diseases and conditions affecting the mouth, jaw, teeth and their supporting tissues (Oxford Medical Dictionary) The work of a dentist ranges from regular patient check-up to orthodontics and surgery....
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
