Effects Of Aging On Apoptosis Gene Expression In Oral Mucosal Tissues, Octavio A. Gonzalez, Michael John Novak, Sreenatha S. Kirakodu, Arnold J. Stromberg, Shu Shen, Luis Orraca, Janis Gonzalez-Martinez, Jeffrey L. Ebersole

Center for Oral Health Research Faculty Publications

Apoptotic processes are important for physiologic renewal of an intact epithelial barrier and contribute some antimicrobial resistance for bacteria and viruses, as well as anti-inflammatory effects that benefits the mucosa. The oral cavity presents a model of host-bacterial interactions at mucosal surfaces, in which a panoply of microorganisms colonizes various niches in the oral cavity and creates complex multispecies biofilms that challenge the gingival tissues. This report details gene expression in apoptotic pathways that occur in oral mucosal tissues across the lifespan, using a nonhuman primate model. Macaca mulatta primates from 2 to 23 years of age (n = …

Evaluation Of Accuracy Of Impression Materials With Different Mixing Techniques, James Ywom

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: To investigate gypsum compatibility and dimensional stability of irreversible hydrocolloid impression materials with three mixing techniques. A comparison between vacuum-mixed, mechanically-mixed and manually-mixed techniques was evaluated for each impression material. Materials and Methods: Three irreversible hydrocolloid impression materials Kromopan 100® (Lascod™), Identic® (Dux dental™), and Jeltrate Plus® (Dentsply™) were tested gypsum compatibility in accordance with ANSI/ADA Specification No. 18 for alginate impression materials. The test for linear dimensional stability was tested in accordance with ANSI/ADA Specification No. 19 for elastomeric impression materials. A One-way ANOVA test was used to analyze dimensional stability at a significance level of (p < 0.05). Conclusion: The vacuum mixing technique facilitates the mixing of irreversible hydrocolloid impression materials and improves the compatibility with gypsum material and reproduces a more dimensionally accurate cast than the other mixing techniques.

Awareness And Beliefs Regarding Intimate Partner Violence Among First-Year Dental Students, Rhonda J. Everett, Karl Kingsley, Christina A. Demopoulos, Edward E. Herschaft, Christine Lamun, Sheniz Moonie, Timothy J. Bungum, Michelle Chino

Environmental & Global Health Faculty Research

Intimate partner violence (IPV) may affect one to four million individuals per year in the United States, with women accounting for the majority of both reported and unreported cases. Dental professionals are in a unique position to identify many types of IPV because injuries to the head and neck may be indicators or predictors of IPV abuse. Fewer than half of dental programs surveyed have reported having IPV-specific curricula, and most dental students surveyed have reported having little experience or training to recognize IPV. Based on this information, this pilot study sought to assess the awareness and beliefs regarding IPV …

Pediatric Dentistry Training For Dentists In Pakistan, Farhan Raza Khan, Sadia Mahmud, Munawar Rahman

Section of Dental-Oral Maxillofacial Surgery

OBJECTIVE: In the last decade, a rapid growth has been observed in the number of dentists due to establishment of number of dental colleges in Karachi, Pakistan. There is an acute dearth of Pediatric Dentistry faculty in Pakistani dental institutions. Similarly, no post graduate Pediatric Dentistry fellowship program exists in the country. The objectives of this study are to map the pattern of pediatric dentistry services provided by the clinicians in teaching institutions and private practices of Karachi. METHODOLOGY: A cross sectional study conducted at dental departments of academic institutions and selected dental practices in different parts of Karachi. The …

Ccl3 And Cxcl12 Production In Vitro By Dental Pulp Fibroblasts From Permanent And Deciduous Teeth Stimulated By Porphyromonas Gingivalis Lps, Carla Renata Sipert, Ana Carolina Morandini, Karin Cristina Da Silva Modena, Thiago José Dionísio, Maria Aparecida Andrade Moreira Machado, Sandra Helena Penha Oliveira, Ana Paula Campanelli, Carlos Ferreira Santos

All Dugoni School of Dentistry Faculty Articles

OBJECTIVE: The aim of this study was to compare the production of the chemokines CCL3 and CXCL12 by cultured dental pulp fibroblasts from permanent (PDPF) and deciduous (DDPF) teeth under stimulation by Porphyromonas gingivalis LPS (PgLPS).

MATERIAL AND METHODS: Primary culture of fibroblasts from permanent (n=3) and deciduous (n=2) teeth were established using an explant technique. After the fourth passage, fibroblasts were stimulated by increasing concentrations of PgLPS (0-10 µg/mL) at 1, 6 and 24 h. The cells were tested for viability through MTT assay, and production of the chemokines CCL3 and CXCL12 was determined through ELISA. Comparisons among samples …

Protaper Rotary Instrument Fracture During Root Canal Preparation: A Comparison Between Rotary And Hybrid Techniques, Huma Farid, Farhan Raza Khan, Munawar Rahman

Section of Dental-Oral Maxillofacial Surgery

AIMS:

This study aimed to compare the frequency of ProTaper rotary instrument fracture with rotary (conventional) and hybrid (rotary and hand files) canal preparation techniques. Secondary objectives were to determine whether there was an association of ProTaper file fracture with the canal curvature and to compare the mean time required for canal preparation in the two techniques.

METHODS:

An in vitro experiment was conducted on 216 buccal canals of extracted maxillary and mandibular first molars. After creating an access cavity and a glide path for each canal, a periapical radiograph was taken and the canal curvature was measured with Schneider's …

Principles Of Periodontology, Andrew R. Dentino, Seokwoo Lee, Jason Mailhot, Arthur F. Hefti

School of Dentistry Faculty Research and Publications

Periodontal diseases are among the most common diseases affecting humans. Dental biofilm is a contributor to the etiology of most periodontal diseases. It is also widely accepted that immunological and inflammatory responses to biofilm components are manifested by signs and symptoms of periodontal disease. The outcome of such interaction is modulated by risk factors (modifiers), either inherent (genetic) or acquired (environmental), significantly affecting the initiation and progression of different periodontal disease phenotypes. While definitive genetic determinants responsible for either susceptibility or resistance to periodontal disease have yet to be identified, many factors affecting the pathogenesis have been described, including smoking, …

Paclitaxel-Induced Apoptosis Is Bak-Dependent, But Bax And Bim-Independent In Breast Tumor, Anna V. Miller, Mark A. Hicks, Wataru Nakajima, Amanda C. Richardson, Jolene J. Windle, Hisashi Harada

Philips Institute for Oral Health Research Publications

Paclitaxel (Taxol)-induced cell death requires the intrinsic cell death pathway, but the specific participants and the precise mechanisms are poorly understood. Previous studies indicate that a BH3-only protein BIM (BCL-2 Interacting Mediator of cell death) plays a role in paclitaxel-induced apoptosis. We show here that BIM is dispensable in apoptosis with paclitaxel treatment using bim−/− MEFs (mouse embryonic fibroblasts), the bim−/− mouse breast tumor model, and shRNA-mediated down-regulation of BIM in human breast cancer cells. In contrast, both bak−/− MEFs and human breast cancer cells in which BAK was down-regulated by shRNA were more resistant to paclitaxel. However, paclitaxel …

Two-Component System Response Regulators Involved In Virulence Of Streptococcus Pneumoniae Tigr4 In Infective Endocarditis, My Trihn, Xiuchun Ge, Alleson Dobson, Todd Kitten, Cindy Munro, Ping Xu

Philips Institute for Oral Health Research Publications

Streptococci resident in the oral cavity have been linked to infective endocarditis (IE). While other viridans streptococci are commonly studied in relation to IE, less research has been focused on Streptococcus pneumoniae. We established for the first time an animal model of S. pneumoniae IE, and examined the virulence of the TIGR4 strain in this model. We hypothesized that two-component systems (TCS) may mediate S. pneumoniae TIGR4 strain virulence in IE and examined TCS response regulator (RR) mutants of TIGR4 in vivo with the IE model. Thirteen of the 14 RR protein genes were mutagenized, excluding only the essential …
