Bactericidal Effects Of Low Temperature Atmospheric Pressure Plasma On Porphyromonas Gingivalis, Arwa Mahasneh
Bactericidal Effects Of Low Temperature Atmospheric Pressure Plasma On Porphyromonas Gingivalis, Arwa Mahasneh
Dental Hygiene Theses & Dissertations
Purpose: The biomedical application of low temperature atmospheric pressure plasma (LTAPP) is a collaborative interest for engineering, medical, dental and biological researchers. This laboratory study tested whether LTAPP can limit growth of Porphyromonas gingivalis, a periodontal pathogen strongly associated with periodontal disease, disease progression, and refractory periodontitis. Methods: After extensive pilot trials, the study consisted of 24 agar plate samples of P. gingivalis- 20 samples were exposed to LTAPP at 5, 7, 9 and 10 minutes and 4 control samples were exposed to helium gas only. Immediately after exposures, the samples were incubated anaerobically for 72 hour at …

This document is our final report describing the research activities carried out under AFOSR Grant FA9550-06-1-0004. First, descriptions of our cold plasma generation systems are presented. Two systems, developed with past and present AFOSR support, are available in our laboratory. The first is a pulsed device capable of emitting a cold plasma plume in room air. The second is an air plasma generator the core of which is a dielectric barrier discharge excited by a high AC voltage. Following these brief descriptions we first present the effects of an atmospheric pressure air plasma on four different types of eukaryotic microalgae. …
Effects Of Low-Temperature Atmospheric Pressure Plasma On Streptococcus Mutans, Margaret Farrer Lemaster
Effects Of Low-Temperature Atmospheric Pressure Plasma On Streptococcus Mutans, Margaret Farrer Lemaster
Dental Hygiene Theses & Dissertations
The recent emergence of low temperature atmospheric pressure plasma (LTAPP) technology has led researchers to explore biomedical applications. The present study set out to determine if LTAPP has the ability to inactivate dental caries causing bacteria, specifically Streptococcus mutans. Methods: A total of 90 samples were processed. Seventy-two samples of S. mutans at 1: 100 dilution in BHI broth were exposed to LTAPP for various time intervals (60, 120, 180, 300 seconds). Eighteen control samples were plated but not exposed to LTAPP. Samples were plated on Mi tis salivarius (MS) agar and incubated 48 hours at 37° C. Colony …

The Advanced Dental Hygiene Practitioner At The Master's-Degree Level: Is It Necessary?, Michele Leonardi Darby
Dental Hygiene Faculty Publications
The article reflects on the Advanced Dental Hygiene Practitioner (ADHP) curriculum proposed by the American Dental Hygienists' Association at the master's degree level. It is stated that dental hygienists and ADHPs can collaborate with other health care professionals for contributing towards the advancement of quality health care to the most vulnerable populations. It is mentioned that preparation at the master's degree is a logical pathway to the expanded scope of practice.
Oral Healthcare In Kenya: Implications For Dental Hygiene Care, Grace Kogi
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 …

Introduction: Cold plasma, also known as Low Temperature Atmospheric Pressure Plasma (LTAPP) is a novel technology consisting of neutral and charged particles, including free radicals, which can be used to destroy or inactivate microorganisms. Research has been conducted regarding the effect of cold plasma on gram-positive bacteria; however, there is limited research regarding its ability to inactivate the spore-formers Geobacillus stearothermophilus and Bacillus cereus.
Purpose: The purpose of this study was to determine if cold plasma inactivates G. stearothermophilus and B. cereus vegetative cells and spores.
Methods: Nine hundred eighty-one samples were included in this study (762 experimental and …
