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

Mahurin 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 subgingival …

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

Mahurin 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 opportunity for …

Barriers To Care And Buyer Behavior In Relation To Oral Hygiene, Allison E. Mccutchen

Mahurin Honors College Capstone Experience/Thesis Projects

How much of an impact do advertising, brand loyalty, and socioeconomic status have on the overall oral-health knowledge and dental care product purchases of consumers? A survey was distributed to collect data on consumers’ background, oral hygiene purchasing habits, and decision making rationales. It was assumed that those with minimal access to care and minimal oral-health knowledge would be purchasing products based on sale prices, or the promise of improved esthetics, whereas consumers with increased access to care would likely make their purchasing decisions based on the recommendations of a dental professional and be potentially more interested in trying new …

The Importance Of Educating Dental And Dental Hygiene Students On The Correlation Between Vitamin D Deficiency And Dental Caries, Sara Brown

Mahurin Honors College Capstone Experience/Thesis Projects

Recent studies from the U.S. National Library of Medicine have shown that vitamin D deficiency is rapidly increasing among the adult population. 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 a …

The In Vivo Granulopoietic Response To Dexamethasone Injection Is Abolished In Perforin-Deficient Mutant Mice And Corrected By Lymphocyte Transfer From Nonsensitized Wild-Type Donors, Pedro Xavier-Elsas, Cassio Luiz Coutinho Almeida-Da-Silva, Bruno Marques Vieira, Daniela Masid-De-Brito

All Dugoni School of Dentistry Faculty Articles

Exogenously administered glucocorticoids enhance eosinophil and neutrophil granulocyte production from murine bone-marrow. A hematological response dependent on endogenous glucocorticoids underlies bone-marrow eosinophilia induced by trauma or allergic sensitization/challenge. We detected a defect in granulopoiesis in nonsensitized, perforin-deficient mice. In steady-state conditions, perforin- (Pfp-) deficient mice showed significantly decreased bone-marrow and blood eosinophil and neutrophil counts, and colony formation in response to GM-CSF, relative to wild-type controls of comparable age and/or weight. By contrast, peripheral blood or spleen total cell and lymphocyte numbers were not affected by perforin deficiency. Dexamethasone enhanced colony formation by GM-CSF-stimulated progenitors from wild-type controls, but not …

Sustained Release Of Calcium Hydroxide From Poly(Dl-Lactide-Co-Glycolide) Acid Microspheres For Apexification, Bernardino Isaac Cerda-Cristerna, Alejandro Breceda-Leija, Verónica Méndez-González, Daniel Chavarría-Bolaños, Héctor Flores-Reyes, Arturo Garrocho-Rangel, Takashi Komabayashi, Aniket S.

Calcium hydroxide (Ca(OH)2) loaded poly(DL-lactide-co-glycolide) acid (PLGA) microspheres (MS) might be employed for apexification requiring a sustained release of Ca++. The aim of this study was to formulate and characterize Ca(OH)2-PLGA-MS. The Ca(OH)2-loaded MS were prepared by either oil-in-water (O/W) or water-in-oil/in-water (W/O/W) emulsion solvent evaporation technique. MS produced by the O/W technique exhibited a larger diameter (18.63 ± 7.23 μm) than the MS produced by the W/O/W technique (15.25 ± 7.37 μm) (Mann Whitney U test P < 0.001). The Ca(OH)2 encapsulation efficiency and Ca++ release were calculated from data obtained by absorption techniques. Ca++ release profile was evaluated for 30 days. The percentage of encapsulation efficiency of the O/W-produced MS was higher (24%) than the corresponding percentage of the W/O/W-produced MS (11%). O/W- and W/O/W-produced MS released slower and lower Ca++ than a control Ca(OH)2 paste with polyethylene glycol 400 (ANOVA 1 way, Tukey HSD P < 0.01). O/W-produced MS released higher Ca++ than W/O/W-produced MS (statistically significant differences with t-Student test). We concluded that Ca(OH)2-PLGA-MS were successfully formulated; the technique of formulation influenced on the size, encapsulation efficiency and release profile. The MS were better sustained release system than the Ca(OH)2 paste.
