Perceptions And Attitudes Of Healthcare Students Towards Marijuana, Carrie Crosby

EWU Masters Thesis Collection

Perceptions of marijuana were studied in healthcare students at EWU. It was found that most students had an average self-reported knowledge of marijuana use. Marijuana comes in several forms such as, edibles, smoked, patches, and lotions. With its recent legalization in Washington State, sales tax alone has accumulated $400 million dollars in the past 3 years. With this increase in use an examination of healthcare students was warranted. Most students also felt there was a need for more education on marijuana and that their current knowledge level was not enough to be competent when talking with patients about use. Overall, …

Clinical And Histomorphometric Outcomes Following The Use Of Small Versus Large Particle Sized Bone Allografts In Ridge Preservation Procedures: A Randomized Clinical Trial, Gentiane Valiquette

All ETDs from UAB

Alveolar ridge preservation at the time of tooth extraction is a commonly performed procedure as it significantly minimizes ridge resorption and allows for more optimal implant placement. The amount of new vital bone has been shown to vary with the use of different types of bone replacement grafts, however, the effect of bone graft particle size on the outcomes following ridge preservation has not been elucidated in the scientific literature. The present randomized clinical trial compared clinically, radiographically and histomorphometrically the use of small- (0.25-1.0mm) versus large- (1.0- 2.0mm) sized particle mineralized cortico-cancellous bone freeze-dried bone allografts (FDBAs) in ridge …

The Effect Of Primary Palatal Repair On Growth In Cleft Lip And Palate Patients, Nadia Abou Kheir

All ETDs from UAB

Cleft lip and palate (CLP) is a facial defect that is represented as a split in the mouth, palate or both. In the United States approximately 4440 babies are born with CLP annually. More than US$600 million are spent on their treatment and mostly on surgical interventions. Considering the high expenses of primary palatal repair, its effect on growth has been controversial. Surgical scaring is postulated as the cause of maxillary hypoplasia. However, this operation has been considered necessary for function and development of speechHowever, this operation has been considered as necessary for better functional and speech outcomes. Materials and …

Endodontic Post Retention With Resin Cements (Ilumi Fiber Post), Faimeena Farheen

All ETDs from UAB

Objectives: Loss of post retention is the leading cause in the cemented post. There is no good method of bonding a fiber post in a post space with resin cements because adhesive cementation into a prepared post space is difficult- due to an inability to place, dry and light cure the adhesive and the cement. A new post system (iLumi) that transmits light to the apex of the post has recently been developed. We want to know if this system will improve post retention in each section (coronal, middle and apical) of the prepared post space and if this curing …

A Randomized Trial To Evaluate The Effect Of Allograft Bone Particle Size On Histomorphometric And Clinical Outcomes Following Ridge Augmentation Procedures, Hussein Basma

All ETDs from UAB

Ridge deficiency is an unfortunate obstacle that obviates the placement of dental implants or results in placing them at an angle that compromises the prosthetic restoration. An ideal volume is essential for implant placement in an optimal three-dimensional position. Several methods for augmenting the alveolar ridge in preparation for implant placement have been described. Autogenous bone grafts, considered to be the “gold standard”, are associated with significant morbidity and require a second surgical site. Guided bone regeneration (GBR), is an alternative technique that use bone-substitute materials as adjuncts to or replacements for autografts in bone augmentation procedures to overcome the …

Comparison Of Three Dimensional Accuracy For Surgical Guided Template Fabrication Using Two Different Implant Planning Software Programs, Natchaya Thitaphanich

Chulalongkorn University Theses and Dissertations (Chula ETD)

Statement of problem: Static computer-assisted implantation system (s-CAIS) has been introduced to implant dentistry for decades. According to previous studies, they were recognised the inaccuracies of actual implant position placed via using static computer-assisted implantation system. These inaccuracies result from an accumulation of every step in the workflow from planning to accuracy assessment. Recently, there are multiple implant planning softwares available. coDiagnostiXTM software and Implant StudioTM software are widely used third-party implant planning softwares which claimed to provide predictable implant placement outcome. However, the effect of softwares used on accuracy of guided surgery in anterior maxilla region has not been …
