Bone Stimulation Implemented Using The L-Prf Technique Within The Clinical Setting In Kentucky And Tennessee, Kyndall A. Hudson

Honors College Capstone Experience/Thesis Projects

Leukocyte Platelet Rich Fibrin (L-PRF) is an autologous graft that is obtained from the patient’s blood. This provides a condensed network of fibrin that is saturated with cytokines, growth factors, and platelets. L-PRF speeds up the healing process and also optimizes bone grafting results.

Dental treatment options are expanding and new techniques within the office setting are constantly being developed. Present treatment modalities can assist with the stimulation of tissue formation after dental surgical procedures, leading to various results. The placement of L-PRF provides enhanced healing following specific dental procedures using the patient’s donor tissue; therefore, reducing the ...


Subgingival Air Polishing In Dentistry, Chelsea T-P. Howell 2015 Western Kentucky University

Subgingival Air Polishing In Dentistry, Chelsea T-P. Howell

Honors College Capstone Experience/Thesis Projects

Modern statistics have shown that periodontal disease is highly prevalent in today’s society. Periodontal disease has detrimental effects to the oral cavity, including: bone less, recession, and tooth mobility. A strong correlation has been linked to the use of the subgingival air polisher on patients with active periodontal disease and the regression of the disease after being treated with the device. This is being compared to traditional hand-scaling beneath the gingiva margin which is less efficient in removing biofilm subgingivally. Recent studies (Petersilka et al.) are confirming this to be true by treating patients with both hand-scaling and the ...

Vitamin D deficiency has many effects on the body, such as bone pain and muscle weakness. A strong correlation has been noticed in humans with vitamin D deficiency and decreased exposure to natural sunlight, which is vital to absorb the vitamin D they have ingested. Those suffering from milk allergies or are following a strict vegan diet may also have some implication of a vitamin D deficiency. Recent studies (Hujoel, 2012) have also shown that there is ...


Periodontal Disease: Molecular Visualization Through Computer Modeling And 3d Printing, Catherine Chatowsky 2015 University of Rhode Island

Periodontal Disease: Molecular Visualization Through Computer Modeling And 3d Printing, Catherine Chatowsky

Senior Honors Projects

Periodontal disease is a common infection that damages gingival tissue and creates jawbone destruction that can lead to the loosening or loss of teeth. Hundreds of diverse bacterial species reside in the harsh environment of the oral cavity. The creation of plaque and biofilms serve to allow the bacteria to avoid immune-mediated destruction. This project analyzed periodontal disease pathogens using molecular printing 3D visualization. Two bacterial species (T. denticola and P. gingivalis) were chosen from the public resource: Research Collaboratory for Structural Bioinformatics: Protein Data Bank. T. denticola was a bacteria found to have a binding protein (FhbB) that structurally ...

Oral Wellness: Using Occupational Therapy To Enhance Oral Hygiene Delivery In Long-Term Care, Lauryn J. Banovitz, Liberty Bellah, Rosemarie Lion

Master's Theses and Capstone Projects

Based on current literature, oral health in long-term care (LTC) facilities is frequently of low priority and does not follow evidence-based best practices. Poor oral health reduces the quality of life of older adult residents and patients and can lead to systemic diseases, such as cardiovascular disease, stroke, and pneumonia, the leading cause of death in LTC. Occupational therapists can play an instrumental role as oral care consultants, and educators, and can act as resource guides to raise the standards of oral care in LTC facilities.

This capstone project explored ways in which occupational therapy, a profession traditionally designated for ...

Brief interactions with 20 patients who were receiving oral care helped put a face to the system and provided an additional perspective on ...


Oral Health Beliefs Of Alaska Native Dental Patients, Abigail N. Adams, Carly T. McKenzie 2015 University of Alabama - Birmingham

Oral Health Beliefs Of Alaska Native Dental Patients, Abigail N. Adams, Carly T. Mckenzie

Washington University Journal of American Indian & Alaska Native Health

This study investigated the oral health beliefs of Alaska Native dental patients via a questionnaire with 4-point Likert scales. Respondents (n = 136) reported high perceived importance of keeping natural teeth. Females viewed oral health as more important than males. Respondents generally did not view dentists as readily available (M = 2.86, SD = 0.66). Perceived availability and efficacy of dentists were positively correlated (r = 0.219, p = 0.021). Beliefs regarding seriousness of dental problems and importance of oral health were strongly correlated (r = 0.547, p < 0.001). Age predicted perceived seriousness of oral health problems, dentist availability, and prevention benefits. Access to dental care is perceived as a barrier among Alaska Natives generally and elders in particular. Oral health education and prevention messages should utilize the existing belief that keeping natural teeth is important. Public information about available services and transportation logistics may decrease perceived availability barriers.

Samples were evaluated histologically and by immunohistochemical staining for areas of new osteoid tissue and new bone tissue ...


The Purpose And Value For Students Of Pbl Groups For Learning, Vicki J. Skinner, Annette Braunack-Mayer, Tracey A. Winning 2015 University of Adelaide

The Purpose And Value For Students Of Pbl Groups For Learning, Vicki J. Skinner, Annette Braunack-Mayer, Tracey A. Winning

Interdisciplinary Journal of Problem-Based Learning

Groups are central to problem-based learning (PBL) and educational and professional outcomes relevant to clinical education. However, PBL groups in practice may differ from theoretical conceptions of groups. Therefore, this study explored students’ understandings of the purpose and value of PBL groups for their learning. We conducted a naturalistic study with novice (first-year) students at two dental schools (Australia, Ireland), using observation and interviews analyzed thematically. Students constructed PBL learning as individual knowledge gain, and group purpose as information gathering and exchange; few students acknowledged the learning potential of group processes. Group value depended on assessment and curriculum context. Findings ...
