Prevalence And Rationale Of Orthodontic Extractions At Loma Linda University, Teresa T. Tran

Loma Linda University Electronic Theses, Dissertations & Projects

Aim: The purpose of this study was to determine the prevalence of orthodontic extraction cases and the rationale for the decision-making. Materials & Methods: The records of consecutive patients who had completed orthodontic treatment at Graduate Orthodontic Clinic, Loma Linda University School of Dentistry, between January 2010 and December 2014 were reviewed for prevalence of orthodontic extractions. Cone beam computed tomograms (CBCTs) of patients, that had extraction(s) prescribed as part of orthodontic treatment, were analyzed dentally and skeletally. Patients were then categorized according to the degree of crowding in each dental arch. A one-way ANOVA (Kruskal-Wallis) test and …

Comparison Of The Kois Dento-Facial Analyzer System With An Earbow For Mounting A Maxillary Cast, Laura H. Lux, Geoffrey A. Thompson, Kenneth J. Waliszewski, Gerald J. Ziebert

School of Dentistry Faculty Research and Publications

Statement of problem: The Kois Dento-Facial Analyzer System (KDFA) is used by clinicians to mount maxillary casts and evaluate and treat patients. Limited information is available for understanding whether the KDFA should be considered as an alternative to an earbow.

Purpose: The purpose of this study was to evaluate maxillary casts mounted using the KDFA with casts mounted using Panadent's Pana-Mount Facebow (PMF). Both articulation methods were compared against a lateral cephalometric radiograph.

Material and methods: Fifteen dried human skulls were used. Lateral cephalometric radiographs and 2 maxillary impressions were made of each skull. One cast from each skull was …

Targeted Salivary Biomarkers For Discrimination Of Periodontal Health And Disease(S), Jeffrey L. Ebersole, Radhakrishnan Nagarajan, David Akers, Craig S. Miller

Center for Oral Health Research Faculty Publications

Generally, clinical parameters are used in dental practice for periodontal disease, yet several drawbacks exist with the clinical standards for addressing the needs of the public at large in determining the current status/progression of the disease, and requiring a significant amount of damage before these parameters can document disease. Therefore, a quick, easy and reliable method of assessing and monitoring periodontal disease should provide important diagnostic information that improves and speeds treatment decisions and moves the field closer to individualized point-of-care diagnostics.

OBJECTIVE: This report provides results for a saliva-based diagnostic approach for periodontal health and disease based upon …

Effect Of Chemical Pocket Disinfection As An Adjunct To Non-Surgical Maintenance Therapy Of Inflamed Periodontal Pockets, Chad Riggs

Theses & Dissertations

Purpose: Scaling and root planing with adjunctive chemical pocket disinfection (SRP+C) utilizing sodium hypochlorite solution has been used to treat inflamed pockets of periodontal maintenance patients for many years, without evidence of its benefits. The primary objective was to determine if SRP+C is more effective than scaling and root planing alone (SRP) in improving clinical outcomes. The secondary objective was to compare the effect of SRP+C and SRP on pro-inflammatory IL-1β, anti-inflammatory IL-1ra, and anti-inflammatory index (IL-1ra/IL-1β ratio) found in gingival crevicular fluid (GCF).

Materials and Methods: Pockets (≥ 5 mm and BOP) of 31 maintenance patients were included. Test …

Prevention Of Experimental Periodontitis In Rats With A Simvastatin Prodrug, Aaron Bradley

Theses & Dissertations

Introduction: Simvastatin (SIM) is a hypolipidemic drug that has been shown to have anti-inflammatory and bone anabolic properties. The aim of this study was to examine the effects of novel locally-applied SIM conjugated with methoxypolyethylene glycol to form micelles (SIM/SIM-mPEG) in an experimental periodontitis model in rats using micro-computed tomography (µ-CT) and histologic evaluation.

Methods: Experimental periodontitis was induced using silk ligatures around the maxillary right second molar (M2) in 40 Sprague-Dawley rats. Rats were divided into five groups using SIM/SIM-mPEG at 0.5, 1.0, or 1.5 mg SIM doses, mPEG-alone or no drug (ligature-alone) injected into the palatal M1-M2 gingiva …

Comparing The Efficacy Of Laser Fluorescence And Explorer Examination In Detecting Subgingival Calculus In Vivo, Mark Mccawley

Student Theses, Dissertations and Capstones

This paper investigated the sensitivity, specificity, accuracy, and precision of laser fluorescence and tactile probing for the detection of subgingival calculus. The gold standard for subgingival calculus detection has always been tactile probing. In this study 27 teeth were collected and 108 surfaces investigated, one tooth was excluded (group #13) where no calculus was observed on any surface, and three surfaces because of subgingival root caries to avoid confounding data, which left a total of 101 surfaces of 26 extracted teeth that meet the investigation criteria. The presence of subgingival calculus was observed on 75 tooth surfaces (74.25%). There was …

Can Dentistry Have Two Contracts With The Public?, David A. Nash

Oral Health Science Faculty Publications

The social contract is an implicit agreement between parts of society and society as a whole. Since the Middle Ages, the learned professions, recently including dentistry, have had a covenantal relationship with the public based on trust, exchanging monopoly privileges for benefiting the public good. Unlike commercial trade in commodities, professional relationships are grounded in ensuring an adequate level of oral health to all. A second contract is emerging where dentists relate to society as business operators, exchanging commodity services for a price. Recent actions by the Federal Trade Commission and the U.S. Supreme Court make it unlikely that dentistry …

Changes In Composite Toxicity Following Exposure To Pulp Capping Materials, Audra Long

Master's Theses (2009 -)

Introduction: Direct pulp capping involves placing a material over the exposed pulp in order to maintain its vitality. For decades, calcium hydroxide (CH) has served as the gold standard for this purpose, but its toxicity to the pulp may negatively impact treatment outcomes. Mineral Trioxide Aggregate (MTA) has become a popular alternative based partly on its excellent biocompatibility. Pulp-capped teeth are often restored with highly toxic composite materials, but the pulp capping material’s ability to alter these toxic effects has never been investigated. The purpose of this in vitro study is to determine the effects of Dycal, a CH-based cement, …

The Direct Effect Of Low-Magnitude High-Frequency Mechanical Vibration On Osteoclast Formation From Raw267.4 Monocytes, Maxwell Antonio Abraham

Master's Theses (2009 -)

Low-magnitude high-frequency (LMHF) mechanical vibration has been demonstrated to enhance bone formation possibly through inhibition of osteoclastogenesis of bone. Earlier research has demonstrated osteoclast formation from RAW264.7 monocytes was inhibited by a chewing cycle mimicking vibration through inhibition of dendritic cell-specific transmembrane protein (DC-STAMP). We hypothesize that application of LMHF mechanical vibration directly inhibits osteoclast formation from RAW264.7 monocytes in a frequency dependent manner. RAW264.7 monocytes (ATCC) were cultured in alpha minimal essential medium (MEM) with 10% fetal bovine serum (FBS ) and 1% Pen/Strep at 37°C and 5% CO2. The cells were seeded at a density of 2000 cells/well …

Influence Of Fluoride And Stress On The Electrochemical Properties Of Nickel-Titanium Coils, Ashley Barnes

Master's Theses (2009 -)

The aim of this study was to examine the effects of fluoride and stress on the electrochemical properties of nickel-titanium coils. Forty Dentsply GAC NiTi coils were divided into four groups of ten and individually tested. Twenty coils were placed in a solution of artificial saliva, where ten of the twenty were compressed and the other ten were not stressed. The other twenty coils were placed in a 1500 ppm NaF solution, where ten were compressed and ten were not. The coils were connected to a computer driven potentiostat and three tests were conducted: open circuit potential monitoring for 2 …
