Effect Of Jagged-1 And Delta-Like1 On The Proliferation And Osteogenic Differentiation Of Primary Deciduous Pulp Cells, Karnnapas Peetiakarawach

Chulalongkorn University Theses and Dissertations (Chula ETD)

Objectives: The purpose of the present study was to investigate the influence of Notch ligands, Jagged-1 and Delta-like1, on the proliferation and osteogenic differentiation of primary deciduous pulp cells in vitro. Methods: Jagged-1 and Delta-like1 ligands were immobilized to the tissue culture surface using indirect affinity immobilization technique. Cell proliferation was determined by a MTT assay and the mRNA expression levels of apoptosis related-genes. The osteogenic differentiation was determined by the ALP activity assay, the mineralization assay, and the mRNA expression levels of osteogenic genes. Statistical analyses were performed using Kruskal-Wallis H followed by Mann-Whitney U. Results: Cell proliferation was …

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

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 …

Operative Management Of Idiophatic Myositis Ossificans Of Lateral Pterygoid Muscle, Luis Eduardo Almeida, Andrea Doetzer, Flavio Camejo, Jose A. Bosio

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.

PRESENTATION OF CASE

A twelve years old female patient presenting with mouth opening of 10 mm, no facial asymmetry, and no jaw …

Racial/Ethnic Disparities In Provision Of Dental Procedures To Children Enrolled In Delta Dental Insurance In Milwaukee, Wisconsin, Pradeep Bhagavatula, Qun Xiang, Fredrick Eichmiller, Aniko Szabo, Christopher Okunseri

School of Dentistry Faculty Research and Publications

Objectives: Most studies on the provision of dental procedures have focused on Medicaid enrollees known to have inadequate access to dental care. Little information on private insurance enrollees exists. This study documents the rates of preventive, restorative, endodontic, and surgical dental procedures provided to children enrolled in Delta Dental of Wisconsin (DDWI) in Milwaukee.

Methods: We analyzed DDWI claims data for Milwaukee children aged 0-18 years between 2002 and 2008. We linked the ZIP codes of enrollees to the 2000 US Census information to derive racial/ethnic estimates in the different ZIP codes. We estimated the rates of preventive, restorative, endodontic, …

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

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 …

Review Found Little Difference Between Sandblasted And Acid-Etched (Sla) Dental Implants And Modified Surface (Slactive) Implants, Gary L. Stafford

School of Dentistry Faculty Research and Publications

Data sources

Medline, Embase, the Cochrane Oral Health Group's Trials Register and OpenGREY databases were searched together with the reference lists of identified articles.

Study selection

Randomised controlled trials (RCTs) and prospective cohort studies of at least six month duration were included. Studies/case series in which there was only one implant surface (SLA or SLActive) and one loading protocol (immediate or early) were also considered.

Data extraction and synthesis

Two reviewers screened, selected and abstracted data, independently. RCTs were assessed for quality using the Cochrane risk of bias approach and observational studies using the Newcastle-Ottawa scale (NOS). The primary outcomes …

Patterns Of Dental Service Utilization Following Nontraumatic Dental Condition Visits To The Emergency Department In Wisconsin Medicaid, Nicholas M. Pajewski, Christopher Okunseri

School of Dentistry Faculty Research and Publications

Objectives: To examine patterns of dental service utilization for adult Medicaid enrollees in Wisconsin following nontraumatic dental condition (NTDC) visits to the emergency department (ED).

Methods: This is a retrospective, observational study of claims for NTDC visits to the ED and dental service encounters from the Wisconsin Medicaid Evaluation and Decision Support database (2001-2009). We used competing risk models to predict probabilities of returning to the ED versus obtaining follow-up care from a dentist.

Results: We observed a 43 percent increase in the rate of NTDC visits to the ED, with most of this increase occurring from 2001 to 2005. …

Management Of Dental Extraction In A Female Patient With Fanconi Anemia, Andre Peisker, Gregor F. Raschke, Arndt Guentsch, Korosh Roshanghias, Stefan Schultze-Mosgau

School of Dentistry Faculty Research and Publications

Oral surgery in patients with bleeding disorders is associated with a high risk of bleeding during and after surgery. This article is aimed to present the case of an eight-year-old girl suffering from severe Fanconi anemia with pancytopenia who underwent a dental extraction. The hemostatic effect of local administration of tranexamic acid in combination with a primary suture seems to be extremely helpful in order to reduce the necessity of blood products and the risk of postoperative bleeding.
