The Effects Of Orthodontic Appliance Base Plate Material, Pmma, Infused With Silver And A Novel Antibacterial Compound On Biofilm Formation, Ryan D. Jolley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Retention is required in the majority of orthodontic patients throughout the remainder of their life. The traditional Hawley style retainer is still considered by many orthodontic professionals to be the gold standard in retention appliances. The orthodontic population, in general, is at a higher risk for caries due to plaque accumulation from poor diet, suboptimal oral hygiene, and often a lack of motivation. A Hawley retainer that reduces caries-causing oral microbes could improve oral health and be very beneficial to the post-orthodontic patient. Developing methods to safely include antibacterial products within the Hawley retainer’s base plate material could help effect …

Oral Microbial Burden Of Periodontal Pathogens Among Orthodontic Patients, David Jolley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objectives

Many research studies involving orthodontic patients have a natural inclination to focus on changes in levels of cariogenic pathogens after bracket placement, and very few studies examine the role of changes of periodontal pathogens – particularly among adult patients. Interestingly, recent evidence suggests that increased levels of a specific periodontal pathogen, Fusobacterium nucleatum, may elevate risk for development of colon cancer in adults through direct pathways. Based upon this new evidence, the objective of the current study was to screen saliva samples taken from orthodontic patients to determine the prevalence of periodontal pathogens, including F. Nucleatum, T. denticola, and …

Collaborative Learning: Students’ Perspectives On How Learning Happens, Abdulaziz Almajed, Vicki Skinner, Ray Peterson, Tracey Winning

Interdisciplinary Journal of Problem-Based Learning

Collaborative learning (CL), a core component of inquiry-based learning approaches, aims to support students’ development of key skills (e.g., working in multidisciplinary teams). To design effective CL activities, we need to understand students’ perceptions about CL. However, few studies have examined students’ understandings of CL. This qualitative study aimed to address this gap by analyzing participants’ constructions of their CL experiences. Focus group data (14 first- and 14 fourth-year dental student volunteers) were analyzed by an inductive thematic analysis strategy. The findings explained students’ perspectives of key factors for facilitating positive learning within an inquiry-based CL context, namely having a …

Another Piece Of The “Silence In Pbl” Puzzle: Students’ Explanations Of Dominance And Quietness As Complementary Group Roles, Vicki J. Skinner, Annette Braunack-Mayer, Tracey A. Winning

Interdisciplinary Journal of Problem-Based Learning

A problem-based learning (PBL) assumption is that silence is incompatible with collaborative learning. Although sociocultural studies have reinterpreted silence as collaborative, we must understand how silence occurs in PBL groups. This essay presents students’ explanations of dominance, leadership, and silence as PBL group roles. An ethnographic investigation of PBL groups, informed by social constructionism, was conducted at two dental schools (in Australia and Ireland). The methods used were observation, interviews, and focus groups. The participants were volunteer first-year undergraduates. Students attributed dominance, silence, and members’ group roles to personal attributes. Consequently, they assumed that groups divided naturally into dominant leaders …

Impact Of Interviews On Heterosexual Students' Expressions Of Cultural Competency, Carol Isaac, Linda Behar-Horenstein

The Qualitative Report

The purpose of this qualitative study was to understand the effects of a cultural competency intervention on dental pre-doctoral students’ attitudes toward individuals of a different sexual orientation. 22 heterosexual students interviewed gay or lesbian individuals and wrote reflective text. Results illustrated that participants found that their interviewees had “surprisingly similar” beliefs and values – especially in the areas of religion and family. Because of their “similar values,” these students expressed respect toward their interviewees who were “so different” than themselves. This conclusion of “sameness” forced them to see homosexuals as people, rather than a stigmatized invisible outgroup, mitigating sexual …
