School of Dentistry Faculty Research and Publications

INTRODUCTION

Myositis ossificans (MO) is characterized as heterotopic bone formation within muscle. MO rarely occurs in the head and neck region. Excision of the heterotopic bone is the standard treatment. This report summarizes a case of a 12-year old female with MO involving the lateral pterygoid muscle. The heterotopic bone was excised using an intraoral incision. Despite intensive physical therapy, the operation failed as evidenced by new bone formation in the area within three weeks of the operation.

Effect Of Curcumin On Tnf-Α-Induced Cyclooxygenase-2 Gene Expression And Prostaglandin E2 Synthesis In Bone Marrow Stromal Cell Line, Varittha Thongtan

Chulalongkorn University Theses and Dissertations (Chula ETD)

The objective of this study was to investigate the effect of curcumin on TNF-α-induced expression of COX-2 and PGE2 synthesis in mouse ST2 bone marrow-derived stromal cells. ST2 cells were treated with TNF-α to determine the optimum concentration and treatment duration for inducing COX-2 expression. Then, ST2 cells were treated with TNF-α in the absence or presence of various concentration of curcumin. COX-2 expression was determined using reverse transcriptase polymerase chain reaction and PGE2 level in culture medium was measured using ELISA. TNF-α at concentrations of 1-50 ng/mL significantly increased COX-2 expression, with the maximum induction at 20 ng/mL. The …

The result showed that porcelain polished with zirconia paste had the highest mean Ra value, porcelains polished with alumina and alumina-zirconia paste had lower Ra values than zirconia paste while porcelain polished weight diamond paste demonstrated …

Effects Of Acemannan Deacetylation On Biological Activity Of Gingival Fibroblast, Jaroenporn Chokboribal

Chulalongkorn University Theses and Dissertations (Chula ETD)

Acemannan extracted from Aloe vera gel is unique in the presence of acetylated mannose residues and was reported to accelerate mice buccal wound healing. In order to assert structural and biological roles of mannose acetyl groups, high-molecular-mass DeAcAM of various DDAs were prepared by alkaline hydrolysis at 80°C for 5 min using varied concentrations of NaOH. All of the DeAcAMs are not cytotoxic to HGFs and their effects on cell proliferation and VEFG and type I collagen expressions were further investigated. In general, bioactivities of the DeAcAMs were lost to some extents upon the removal of the mannose acetyl groups …

Bioerodible Calcium Sulfate Bone Grafting Substitutes With Tailored Drug Delivery Capabilities, Bryan R. Orellana

Theses and Dissertations--Biomedical Engineering

Bone regeneration or augmentation is often required prior to or concomitant with implant placement. With the limitations of many existing technologies, a biologically compatible synthetic bone grafting substitute that is osteogenic, bioerodible, and provides spacing-making functionality while acting as a drug delivery vehicle for bioactive molecules could provide an alternative to ‘gold standard’ techniques.

In the first part of this work, calcium sulfate (CS) space-making synthetic bone grafts with uniformly embedded poly(β-amino ester) (PBAE) biodegradable hydrogel particles was developed to allow controlled release of bioactive agents. The embedded gel particles’ influence on the physical and chemical characteristics of CS was …

Oral Health Literacy Of Parents And Dental Service Use For Children Enrolled In Medicaid, Angel Smith

Walden Dissertations and Doctoral Studies

Many people in the United States have untreated dental disease due to a lack of dental insurance, a lack of oral health knowledge, and a lack of priority placed on dental health. Despite an increase in dental service use by Medicaid recipients as a result of local programs, children enrolled in Medicaid often have low rates of use of dental services. Using the health literacy framework of the Paasche-Orlow and Wolf (POW) model, the purpose of this study was to explore to the relationship between oral health literacy of parents and dental service use for children enrolled in Medicaid and …

Detection Of Scardovia Genus From Oral Samples In Children Using Real-Time Quantitative Polymerase Chain Reaction, Jungyi Alexis Liu

All ETDs from UAB

Streptococcus mutans (Sm) and Streptococcus sobrinus (Ss) , are considered the major bacterium associated with dental caries. However, recent findings identify Scardovia species (Sc) is associated with early childhood caries, with or without the presence of Sm or Ss. This IRB approved study quantified the presence of Sm and Sc in saliva by real-time quantitative PCR (qPCR) in relation to caries. Saliva samples were collected from 72 preschool children in a high-caries risk community in rural Alabama. SYBR Green-based qPCR using extracted DNA and primers specific for Sm, Ss, Sc and total bacteria determined the copy number (CN/ml). Twenty two …

Section of Dental-Oral Maxillofacial Surgery

Background: Correction of orthodontic asymmetries is crucial to achieve functional occlusion, aesthetics and stability of post orthodontic treatment results. To date valid frequency data of dentofacial asymmetries in Pakistani orthodontic patients do not exist to document orthodontic treatment need. The objectives of this study were to determine frequency of dento-facial asymmetries, severity of dental asymmetries and to determine difference in frequency of dentofacial asymmetries in mixed and permanent dentition.
Methods: The sample of this cross-sectional study comprised of 280 patients (177 females and 103 males) with no history of previous orthodontic treatment having no craniofacial anomalies. Dento-facial asymmetries were assessed …

The Effect Of Canal Preparation On Fill Length In Straight Root Canals Obturated With Guttacore®, Robert Bryan Whitten

MUSC Theses and Dissertations

Introduction: A common critique of using thermoplasticized obturators is the incidence of overextension. It would be of benefit to clinicians to have a technique for canal preparation that would allow for predictable length control. This study compared straight canals instrumented to a size 40 file using a 0.04 standardized taper preparation (STP) with a varied taper preparation (VTP) by evaluating the extension of GuttaCore® (GC) obturators (Dentsply Tulsa Dental, Tulsa, OK). Methods: Eighty extracted mature human premolars with single straight canals were randomly divided into 2 experimental groups (n = 40). Group 1 was instrumented to size 40/.04 at working …

Fasl Expression In Articular Discs Of Human Temporomandibular Joint And Association With Osteoarthrosis, Flavio De Alcantara Camejo, Luis Eduardo Almeida, Andrea Doetzer, Karina Sao Thiago Caporal, Viviane Ambros, Marina Azevedo, Luciana Reis Azevedo Alanis, Marcia Olandoski, Lucia Noronha, Paula C. Trevilatto

School of Dentistry Faculty Research and Publications

Background

Apoptosis is a programme of cell death which does not induce an inflammatory response. Recent previous research has suggested a correlation between temporomandibular internal derangement and apoptosis. Fas ligand (FasL) is an apoptosis‐inducing factor, known to trigger apoptosis through distinct signal pathways. This study aims to examine, by immunohistochemistry, the expression of FasL in temporomandibular joint (TMJ) articular discs of patients with anterior disc displacement with reduction (ADDwR) and without reduction (ADDwoR) in patients with and without osteoarthrosis (OA).

Methods

Forty‐two (n = 42) TMJ articular discs were divided into two cut‐offs: (i) 8 control, 17 ADDwR, 17 …

Replication Of Known Dental Characteristics In Porcine Skin: Emerging Technologies For The Imaging Specialist, L. Thomas Johnson, Thomas W. Radmer, Dean C. Jeutter, Gary L. Stafford, Joseph Thulin, Thomas Wirtz, George Corliss, Kwang Woo Ahn, Alexis Visotky, Ronald L. Groffy

School of Dentistry Faculty Research and Publications

This study demonstrates that it is sometimes possible to replicate patterns of human teeth in pig skin and determine scientifically that a given injury pattern (bite mark) correlates with the dentitions of a very small proportion of a population dataset, e.g., 5 percent or even 1 percent. The authors recommend building on the template of this research with a sufficiently large database of samples that reflects the diverse world population. They also envision the development of a sophisticated imaging software application that enables forensic examiners to insert parameters for measurement, as well as additional methods of applying force to produce …
