Passive Self-Ligating Brackets Vs. Conventional Brackets: Is There A Difference In The Transverse Dimension? A Systematic Review And Meta-Analysis, Justin Scott Tenbrook

Graduate Theses, Dissertations, and Problem Reports

Background and Objectives:

Self-ligating brackets have risen in popularity in clinical orthodontics, but many claims made by their manufacturers have been made without substantial evidence. Any differences among the bracket types are very small when consulting new peer reviewed literature testing their differences. Nevertheless, self-ligating brackets are still purported to be able to increase the dental transverse dimension more effectively than conventional brackets. In 2018, Yang et al. performed a systematic review on the transversal changes, space closure, and efficiency of conventional and self-ligating appliances. Since then, there were several clinical trials published in the literature comparing the mandibular arch …

Immediate Loading Of 4 Guided Implants Supporting A Maxillary Overdenture Using A Novaloc Retention System, Doheum Choi

Graduate Theses, Dissertations, and Problem Reports

The purpose of this study was to test the treatment concept of maxillary overdenture retained by four unsplinted implants placed using a flapless guided approach and immediate loading with Novaloc® attachments. Subjects with fully edentulous maxillae received 4 BLX implants (Roxolid®, SLActive®, 3.75mm diameter, Institut Straumann AG, Basel, Switzerland) to support an immediately loaded overdenture. Implants were connected with Novaloc® attachments (Institut Straumann AG, Basel, Switzerland) immediately following surgery if insertion torque (IT) reached 20 N/cm or above. The primary outcome variable was the radiographic bone level change at 6- and 12-months following implant placement. Secondary outcome variables were peri-implant …

Survival Rate Of Dental Implants Placed In Alveolar Ridge Preservation Sites - Systematic Review, Sravanthi Papisetti

Graduate Theses, Dissertations, and Problem Reports

Introduction: It is not known so far performing Alveolar Ridge Preservation (ARP) in a freshly extracted socket with intact walls would improve clinical outcomes of implants placed in these sites. It is not known whether different biomaterials and techniques would affect the survival of dental implants.

Aim: The current systematic review is undertaken to assess the survival rate of dental implants placed in these sockets and to assess different socket graft materials as well as techniques of ridge preservation with regard to the survival of implants.

Material methods: Search for relevant articles was done in Medline (PubMed). No …

Accuracy, Prosthetic Outcomes, And Patient-Related Outcomes With Immediate Loading Of 4-Guided Implants Supporting An Unsplinted Maxillary Implant-Retained Overdenture, Nathaniel Chertok

Graduate Theses, Dissertations, and Problem Reports

Aim: Assess the accuracy of implant placement using a mucosa-supported surgical guide relative to the planned implant position and examine patient-related outcomes associated with immediately-loaded Mx IOD using a single-attachment abutment system. The secondary aim of the study is to examine the prosthetic complications associated with this treatment.

Materials and methods: Fifteen individuals with edentulous maxillae were included. Each participant received 4 Straumann BLX implants through a stereolithic mucosa-supported surgical guide distributed in the Mx arch to maximize AP spread. Implant lengths ranged from 10 to 14 mm. A post-op CBCT was taken after the surgery to compare …

Current Practices Used To Increase The Success Rate Of The Inferior Alveolar Nerve Block In Mandibular Molars With Symptomatic Irreversible Pulpitis, Nishtha Chauhan

Graduate Theses, Dissertations, and Problem Reports

Introduction: Pain control during endodontic access is important to ensure patient comfort. Achieving adequate anesthesia in an acutely inflamed mandibular molar poses a treatment challenge as the reported failure rate is 30- 83%. A number of pre-medications, anesthetic techniques and adjuncts have been researched to determine their effect on the anesthetic success of the inferior alveolar nerve block (IANB). The purpose of this research was to describe the current clinical practices used by the members of the American Association of Endodontists in pain control of inflamed mandibular molars.

Methods: A cross-sectional observational study design was used. The study …

Cbct Use In Orthodontic Residency Programs In Usa, Su Min Han

Graduate Theses, Dissertations, and Problem Reports

Background and Objectives: Cone beam computed tomography (CBCT) scans in dentistry have been up and coming forms of x-ray technology that allows cross-sectional images to form a comprehensive 3-dimensional representation of the mouth. While the typical use for CBCT imaging is reported to be for implant dentistry, there are many contexts in which it is indicated in orthodontics. There are various schools of thought regarding when CBCT is indicated for specific diagnosis of problems or general use in the collection of initial, progress and post-treatment orthodontic records. There are programs that follow the Radiology guidelines for taking CBCT scans10 and …

Zonulin As A Mediator Of Psychological Stress And Periodontal Disease, Casey D. Wright

Graduate Theses, Dissertations, and Problem Reports

The prevalence of chronic inflammatory diseases is on the rise. Some have posited the permeability of tight junctions in gastrointestinal epithelium tissues as a potential mechanism for precipitating inflammatory processes throughout the body. Zonulin is the only known modulator of tight junction permeability and has been implicated in numerous chronic inflammatory processes (e.g., proinflammatory cytokine production) and diseases, more generally. The role of zonulin in oral inflammation, however, has yet to be explored. Periodontal disease is the most common oral inflammatory condition and primary perpetrator of tooth loss. Periodontal disease also is associated with a number of other health problems …

Medicaid In The Orthodontic Community: Provider Trends And Perceptions, Miranda L. Fabrega

Graduate Theses, Dissertations, and Problem Reports

Background and Objectives: Medicaid is a federal and state insurance program aimed at helping economically disadvantaged individuals and families with gaining access to health care. Lack of provider participation in the Medicaid program leaves many Medicaid-eligible individuals with the inability to obtain certain medical services, such as orthodontic care. The objective of this study was to use an electronic survey to better understand the beliefs and behaviors of orthodontists in regard to participation in the Medicaid program, and to determine if differences exist between Medicaid providers and non-Medicaid providers. Experimental Design and Methods: Survey: Requests to participate in an electronic …

Cytotoxic Effects Of Potential Irrigants For Endodontic Surgery, Kaiying Haggard

Graduate Theses, Dissertations, and Problem Reports

Purpose: The aim of this study is to investigate if hypochlorous acid (Vashe and Endocyn), Ozone, sodium hypochlorite (0.5% NaOCl), chlorhexidine (0.12% CHX), and MTAD can be used as a disinfectant for endodontic surgery without causing bone tissue toxicity by comparing their cytotoxic effects to saline on osteoblasts in vitro.

Methods: Human Fetal Osteoblast Cells (hFOB 1.19, ATCC CRL-11372) were used. The cells viability after 10-minute exposure of Vashe, Endocyn, Ozone, NaOCl (0.5%), CHX (0.12%), MTAD, and saline at concentrations of 10, 30, 60, 90 % volume ratio were measured using CCK8 analysis and the absorbance were measured at 450 …
