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 …

Bactericidal Effects Of Cold Plasma Technology On Geobacillus Stearothermophilus And Bacillus Cereus Microorganisms, Angela D. Morris, Gayle B. Mccombs, Susan L. Tolle, Mounir Laroussi, Wayne L. Hynes

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 …

Debate: A Teaching-Learning Strategy For Developing Competence In Communication And Critical Thinking, Michele Darby

Dental Hygiene Faculty Publications

The article highlights key benefits from debate as a teaching-learning strategy for developing critical thinking and analytical skills while fostering teamwork and communication. According to the author, it is an effective pedagogical strategy because of the level of responsibility for learning and active involvement required by all student debaters. She also notes that the debate strategy can be used as a method to achieve competencies in baccalaureate and graduate dental hygiene programs.

Effects Of Tooth Whitening Use On Oral Health Interests And Values In Adults, Katie Jo Ballantyne Sargent

Dental Hygiene Theses & Dissertations

The primary purpose of this study was to determine if tooth whitening product use influences oral health interests and values in an adult population. A two-group, randomized, pre-test, multiple post-test design was used for studying 60 adults between the ages of 18 and 60. Persons who use tobacco products, have composite/tooth-colored anterior restorations, less than eight anterior teeth, pregnant or lactating women, or those who have previously used a whitening product other than toothpaste were excluded from the study. At baseline, a researcher-designed Oral Health Questionnaire was administered to consenting adults to determine the level of oral health interests and …

Effects Of Five Different Finger Rest Positions On Arm Muscle Activity During Scaling By Dental Hygiene Students, Mary Elizabeth Cosaboom

Dental Hygiene Theses & Dissertations

This study was conducted to determine the effects of five different finger rest positions, (fulcrums: opposite arch, standard intra-oral, basic extra-oral, cross arch and finger on finger) on the muscle activity of four forearm muscles, (extensor carpi radialis longus, flexor carpi ulnar is, biceps brachii and pronator teres) during a simulated periodontal scaling experience. A convenience sample of 32 consenting right handed senior dental hygiene students who met inclusion criteria participated. The 32 students had no history of injuries or disabilities to the right arm, wrist, or hand. Pre-test maximum voluntary isometric contraction (MVIC) scores were obtained prior …

Vital Tooth Whitening Effects On Oral Health-Related Quality Of Life In Older Adults, Ann Michelle Poindexter

Dental Hygiene Theses & Dissertations

This study determined if vital tooth whitening affects oral health-related quality of life (OHRQOL) in adults ≥50-years old, and if tooth whitening promotes individuals to seek regular professional dental care and participation in social activities. Using a two-group, single blind, randomized, pre-test-post-test design, 62 participants were enrolled. The experimental group used a whitening product twice daily for three weeks, while the control group used no whitening products. Tooth color satisfaction was assessed using the Tooth Color Satisfaction Scale and was correlated with overall oral health-related quality of life. The Oral Health Impact Profile (OHIP), used as the pre-test …

Bactericidal Effects Of Cold Plasma Technology On Geobacillus Stearothermophilus And Bacillus Cereus Microorganisms, Angela Dawn Morris

Dental Hygiene Theses & Dissertations

Non-equilibrium atmospheric pressure plasma, also known as cold plasma, is a state of matter that consists of a mix of neutral and charged particles. Plasma generates chemically reactive species and ultraviolet radiation making them useful in decontamination applications (Kong & Laroussi, 2003). Research regarding the inactivation of gram-positive bacteria, such as Bacillus atrophaeus, by cold plasma has been studied by Laroussi et al. (2003); however, there is limited research regarding the germicidal effectiveness of cold plasma on the microorganisms Geobacillus stearothermophilus and Bacillus cereus. The purpose of this study was to determine if cold plasma technology inactivates heat …

This historical review encompasses selected literature that acknowledged dental Hygienists' direct involvement in U.S. school-based or school-linked oral health programs from 1970-1999.

METHODS: Five researchers independently searched MEDLINE, PubMed, and other electronic databases to identify relevant literature for the years 1970-1999. The search aimed to locate articles authored by or that documented dental Hygienists' involvement as "service provider" in U.S. school-based oral health programs. For the purpose of this review, service provider was …

Changing Perspectives On The Use Of Antimicrobial Mouthrinses, Michele Leonardi Darby

Dental Hygiene Faculty Publications

As oral health care professionals, we need to make evidence-based recommendations to our patients. Studies from which we derive our recommendations need to have been conducted with scientific rigor and need to be confirmed with other welldesigned studies. Given the numerous, long-term, peer-reviewed published studies on antimicrobial mouthrinses with consistent statistically and clinically significant outcomes, it is time to change our professional thinking and practices.

Antimicrobial Mouthrinses In Contemporary Dental Hygiene Practice: The Take Home Message, Michele Leonardi Darby

Dental Hygiene Faculty Publications

The article discusses the significance of antimicrobial mouthrinses to the oral hygiene of people in the U.S. Such product is vital to those with or without dental problems because its regular use reduces supragingival plaque and gingivitis. Studies reveal that an American Dental Association (ADA)-Accepted antimicrobial mouthrinse can result in a greater reduction in plaque and gingivitis than brushing
