Effects of Low-Temperature Atmospheric Pressure Plasma on \u3ci\u3eStreptococcus Mutans\u3c/i\u3e

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 forming units (CFU) were counted and inactivation factor (IF) were determined. Data were analyzed using repeated measures ANOVA at 0.05a significance. Results: Analysis revealed a statistically significant bactericidal effect of LTAPP on S. mutans at time exposures of 60, 120, 180, 300 seconds (p=0.272, p=0.0001, p=0.0001, p=0.0001, respectively). Conclusion: LTAPP had a statistically significant bactericidal effect on S. mutans at all time exposures, as measured by CFU/mL counts and inactivation factors that ranged from 53-95%

Injury Prevention with Physical Therapy

(First paragraph) Ergonomics is the study of human performance (positioning and movement) and workplace design, such as equipment, ambience, and placement. The purpose of ergonomics is to maximize productivity by increasing safety, improving work quality, reducing operator fatigue and discomfort, and decreasing the risk of work -related musculoskeletal disorders (MSDs).1-

Oral Care in the Long-Term Care of Older Patients: How Can the Dental Hygienist Meet the Need?

It is estimated that the older population, aged 65 and older, will make up over 20% of the U.S. population by the year 2030. Research acknowledges about 4% of the older population resides in long-term care facilities (LTCFs), where the long-term older patient (LTOP) is under the formal supervised care or custody of institutions with skilled nurses. By the year 2040, 4 million geriatric residents are predicted to move into LTCFs in the U.S. In 2000, the Surgeon General reported LTOPs in LTCFs have greater oral hygiene needs than any other segment of the population to include: root caries, periodontal disease, xerostomia, fungal infections and other oral health concerns. Serious systemic health conditions occurring at high incidence rates have been linked to poor oral hygiene in the LTOP. The purpose of this manuscript is to identify systemic health conditions, oral health conditions, barriers to oral care for LTOPs and to offer recommendations for increased access to care within LTCFs through the use of registered dental hygienists (RDHs)

Perceptions of the Counseling Profession: From Health Science Graduate Faculty and Students

Counseling is considered a newer healthcare profession and possibly unknown to others. This study uses a post-positivist phenomenological approach exploring healthcare faculty and students\u27 perceptions of counseling professionals after participating in a semester long interprofessional health promotions and maintenance course. Results indicated most professions are unaware of counselors, their scope of practice, and their benefit to interprofessional teams. Participants showed growth in their knowledge. Results indicate the importance of interprofessional education and need for advocacy awareness

Electromyographical Assessments of Recommended Neck and Trunk Positions for Dental Hygienists

Purpose: Dental professionals are recommended to limit neck and trunk flexion to within 20° of a neutral (0°) body posture, however empirical support for the recommendations is lacking. The purpose of this study was to determine whether there are differences in muscle workload between a range of neck and trunk postures in a population of dental hygiene students. Methods: Fifteen first semester senior dental hygiene students with no history of neck and trunk injury volunteered to participate. Surface electromyography was used to record muscle activity from two neck extensors muscles, cervical erector spinae (CES) and upper trapezius (UT), and two trunk extensor muscles, thoracic erector spinae (TES) and iliocostalis lumboruni (IL). Participants performed ten conditions, including five neck flexion angles (0°, 10°, 20°, 30°, 40°) and five trunk flexion angles (0°,10°, 20°, 30°, 40°). For each trial, posture was checked with a goniometer and maintained for 20s. Muscle activity for each muscle was normalized to the individual\u27s maximum voluntary isometric contraction (MVIC). Results: Activity of the CES was significantly lower in the neutral position than all flexed neck positions. Activation of the UT increased with neck flexion but required 30° of flexion to differ significantly from the neutral position. Activity of the TES required 20° of trunk flexion to differ significantly from neutral and IL activity in the neutral position was significantly lower than all other trunk flexion conditions. Conclusion: Even small amounts of neck or trunk flexion (10°), within the recommended range (≤ 20°), can significantly increase the workload for some muscles in an oral health care provider

A Brief Motivational Intervention for Heavy Alcohol Use in Dental Practice Settings: Rationale and Development

Although brief alcohol interventions have proven effective in a variety of health care settings, the present article describes the development of the first brief intervention for heavy drinkers in dental practice. Elements of motivational interviewing and personalized normative feedback were incorporated in a 3- to 5-minute intervention delivered by dental hygienists. The intervention is guided by a one-page feedback report providing personalized normative feedback regarding the patient\u27s current oral health practices, their drinking in comparison to others, and oral cancer risk associated with current smoking and drinking. Future publications will present data regarding intervention effectiveness from an ongoing randomized trial
