The practice of oil pulling or oil swishing is a time-honored Indian folk remedy that involves swishing edible oil in the mouth for oral and systemic health benefits. Oil pulling offers a naturalistic approach to oral health care for a growing body of individuals who desire alternative and complementary medicine. The purpose of this paper was to summarize published research on the effectiveness of oil pulling on oral health. Literature was retrieved from 1992-2011 through databases including Cumulative Index to Nursing and Allied Health Literature (CINAHL), Education Resources Information Center (ERIC), Medical Literature Analysis and Retrieval System Online (MEDLINE), and …


In Vitro Antimicrobial Effect Of A Cold Plasma Jet Against Enterococcus Faecalis Biofilms, Chunqi Jiang, Christoph Schaudinn, David E. Jaramillo, Paul Webster, J. William Costerton Jan 2012

In Vitro Antimicrobial Effect Of A Cold Plasma Jet Against Enterococcus Faecalis Biofilms, Chunqi Jiang, Christoph Schaudinn, David E. Jaramillo, Paul Webster, J. William Costerton

Bioelectrics Publications

The hypothesis that a cold plasma jet has the antimicrobial effect against Enterococcus faecalis biofilms was tested in vitro. 27 hydroxyapatite discs were incubated with E. faecalis for six days to form a monoculture biofilm on the disc surface. The prepared substrata were divided into three groups: the negative control, the positive control (5.25% NaOCl solution), and the plasma treatment group. Resultant colony-forming unit counts were associated with observations of bacterial cell morphology changes using scanning electron microscopy (SEM). Treatment of E. faecalis biofilm with the plasma and 5.25% NaOCl for 5min resulted in 93.1% and 90.0% kill (P < 0.0001), respectively. SEM detected that nearly no intact bacteria were discernible for the plasmaexposed HA disc surfaces. The demonstrated bactericidal effect of the plasma with direct surface contact may be due to the enhanced oxidation by the locally produced reactive plasma species.


Effects Of Low Temperature Atmospheric Pressure Plasma On Tooth Whitening, Denise Michelle Claiborne Oct 2011

Effects Of Low Temperature Atmospheric Pressure Plasma On Tooth Whitening, Denise Michelle Claiborne

Dental Hygiene Theses & Dissertations

Low temperature atmospheric pressure plasma (LT APP) is a novel science being studied as an alternative light source to enhance tooth whitening. The safety and effectiveness of LTAPP has not been established therefore; the purpose of this study was to determine if LTAPP along with H2O2 gel would safely and effectively accelerate the tooth whitening process, in terms of lightness and temperature. Two treatment groups were utilized: 36% H2O2 gel only and 36% H2O2 gel plus LT APP. Control group received no treatment. Experimental teeth were exposed to LT APP at …

Community & Environmental Health Faculty Publications

Background

Dental health is a neglected aspect of adolescent health globally but more so in low-income countries. Secondary analysis using the 2004 Zambia Global School-Based Health Survey (GSHS) was conducted in which we estimated frequencies of relevant socio-demographic variables and explored associations between selected explanatory variables and self-reported poor oral hygiene (not cleaning or brushing teeth) within the last 30 days of the completion of questionnaire.

Findings

Most of the 2257 respondents were males (53.9%) and went hungry (82.5%). More than 4 in 10 respondents drank alcohol (42.2%) while 37.2% smoked cannabis. Overall 10.0% of the respondents reported to have …

Oral Healthcare In Kenya: Implications For Dental Hygiene Care, Grace Kogi

Dental Hygiene Master's Papers and Projects

This paper is a review of literature describing the educational, healthcare delivery and healthcare finance systems in Kenya. The document discusses the unmet oral health needs of the Kenyan population and how implementing the role of the dental hygienist would positively impact oral health promotion throughout the country. Kenyan communities experience all of the major environmental determinants of oral disease, e.g., widespread poverty, underdevelopment, outdated dental equipment, insufficient supply and distribution of qualified dental care professionals and lack of preventive oral health services. About six in ten Kenyans are unable to afford healthcare, clothing, or food; therefore, oral healthcare has …

Bisphenol A Blood And Saliva Levels Prior To And After Dental Sealant Placement In Adults, Joyce Marie Downs Jul 2008

Bisphenol A Blood And Saliva Levels Prior To And After Dental Sealant Placement In Adults, Joyce Marie Downs

Dental Hygiene Theses & Dissertations

Placement of pit and fissure dental sealants is an effective therapy for tooth decay prevention and is widely accepted as a standard of care throughout the United States. Pit and fissure dental sealants (sealants) are manufactured using the resin component of composite dental materials, formed by reacting glycidyl methacrylate with bisphenol A. Bisphenol A (BPA) is a hormonally active, synthetic chemical that is part of a broad group of chemicals known as endocrine disrupting compounds, xenoestrogens, which mimic bioactivity of estrogen. This study measured BP A in saliva and blood after the placement of a widely used, pit and fissure …

In Vitro Evaluation Of The Reciprocating Disposable Prophylaxis Angle Versus The Rotating Disposable Prophylaxis Angle In Extrinsic Stain Removal Effectiveness, Inma Lacross, Michele Darby, Sharon S. Stull, Carlene M. Lynch

Dental Hygiene Faculty Publications

This study determined the extrinsic tooth stain removing effectiveness of a 90° counter-rotational disposable prophylaxis angle (DPA) with rubber cup compared to the traditional 360° unirotational DPA with rubber cup. Four randomly-assigned groups of cleaned, sterilized, extracted human teeth, artificially stained with coffee, tea, tobacco, and red wine, were polished on the buccal and lingual surfaces using one of the 2 DPAs. Each dependent variable (4 different stain types) was tested 4 times with each prophylaxis angle, using 4 prophylaxis paste conditions, and 3 different rpm; therefore, 2 trials x 2 angles x 3 speeds x 4 stains x 4 …

Dental Hygiene Faculty Publications

Cold plasma is a state of matter that contains a large number of particles that are electrically charged. Plasmas generate chemically reactive species and ultraviolet radiation making them useful in decontamination applications (Kong & Laroussi, 2003). Research regarding the inactivation of gram-positive bacteria by cold plasma has been studied by Laroussi et al (2003); however, there is limited research regarding the germicidal effectiveness of cold plasma on Geobacillus stearothermophilus and Bacillus cereus microorganisms. The purpose of this study was to determine if cold plasma technology inactivates Geobacillus stearothermophilus and Bacillus cereus vegetative cells and spores. This study consisted of 981 …
