BACKGROUND: Screening for medical conditions (MCs) of public health importance is a first step in disease prevention and control. Prior studies in the United States found oral health care providers (OHCPS) embrace screening for increased risk of medical conditions in the dental setting. Our objectives were to assess Saudi Arabian (SA) dentist's attitudes, willingness and perceived barriers towards implementing screening for MCs into their dental practices.

METHODS: A self-administered, 5-point Likert Scale (1 = very important/willing to 5 = very unimportant/unwilling) questionnaire was given to a convenience sample of 190 practicing dentists. Friedman nonparametric analysis of variance was used to …

A new study by Fraser et al (2018) urges the use of phylogenetic comparative methods, whenever possible, in analyses of mammalian tooth wear. We are concerned about this for two reasons. First, this recommendation may mislead the research community into thinking that phylogenetic signal is an artifact of some sort rather than a fundamental outcome of the evolutionary process. Secondly, this recommendation may set a precedent for editors and reviewers to enforce phylogenetic adjustment where it may unnecessarily weaken or even directionally alter the results, shifting the emphasis of analysis from common patterns manifested by large clades to rare cases.

The prevalence of edentulism is common worldwide. While improvements in access to healthcare and dental care are reducing the prevalence rate of edentulism, the rapidly growing number of elderly as a percent of the global population will sustain a need for denture therapy for the foreseeable future. While denture use has positive impacts on the quality of life, their use is associated with some problems and risks. Denture stomatitis, a chronic infection-related inflammatory disorder of the oral mucosa, is extremely common and has been reported to occur in up to two-thirds of denture wearers. Importantly, epidemiology studies have shown edentulism …


Oral Biofilms: Development, Control, And Analysis, Daniela Berger, Aviva Rakhamimova, Andrew Pollack, Zvi G. Loewy Jan 2018

Oral Biofilms: Development, Control, And Analysis, Daniela Berger, Aviva Rakhamimova, Andrew Pollack, Zvi G. Loewy

Touro College of Pharmacy (New York) Publications and Research

The oral cavity harbors hundreds of microbial species that are present either as planktonic cells or incorporated into biofilms. The majority of the oral microbes are commensal organisms. Those that are pathogenic microbes can result in oral infections, and at times can initiate systemic diseases. Biofilms that contain pathogens are challenging to control. Many conventional antimicrobials have proven to be ineffective. Recent advances in science and technology are providing new approaches for pathogen control and containment and methods to characterize biofilms. This perspective provides (1) a general understanding of biofilm development; (2) a description of emerging chemical and biological methods …


The Effects Of Drug Abuse On Oral Health, Betzalel Krasnow Jan 2018

The Effects Of Drug Abuse On Oral Health, Betzalel Krasnow

The Science Journal of the Lander College of Arts and Sciences

Drug abuse, currently a national epidemic affecting millions of Americans, causes numerous health issues including increased dental disease. There are several factors which can contribute to an increase in caries and missing teeth. One of the most discussed mechanisms is xerostomia. Drug abusers tend to have large sugar intakes which exacerbates the problems caused by xerostomia. Drug abusers are also at risk for oral infections associated with dental decay due to their altered saliva composition. Unfortunately, once the symptoms are present there is little that can be done to correct them and the goal of the treating dentist should be …

MicroRNAs (miRNAs) are short, noncoding RNAs involved in the regulation of several processes associated with inflammatory diseases and infection. Bacterial infection modulates miRNA expression to subvert any innate immune response. In this study we analyzed, using microarray analysis, the bacterial modulation of miRNAs in bone marrow-derived macrophages (BMMs) in which activity was induced by infection with Porphyromonas gingivalis The expression of several miRNAs was modulated 3 h postinfection (at a multiplicity of infection of 25). A bioinformatic analysis was performed to further identify pathways related to the innate immune host response under the influence of selected miRNAs. To assess the …

This study aims to consider the microbial distribution in oral disease, as well as gene analysis and expression, in elucidating: 1, the fundamental underpinnings of oral disease, and 2, the potential relationship between oral diseases and systemic health. A key focus is identifying the microbiota associated with oral disease manifestations characterized by both conventional microbiological and molecular methods. Variations in the observed microbial populations characterized by conventional and molecular approaches have been identified for caries, periodontitis, peri-implantitis, and stomatitis. The discovery of therapeutic approaches for oral disease will require comprehensive microbial and genomic analysis. This study evaluated the current state …


The Effects Of Sports Drinks On Teeth, Gabriel Kaye Jan 2017

The Effects Of Sports Drinks On Teeth, Gabriel Kaye

The Science Journal of the Lander College of Arts and Sciences

With a push towards a more active lifestyle, the sports drink industry has grown substantially in recent years. However, despite their popularity, sports drinks contain acid, giving them extremely low pHs, which can cause erosion. There have been many studies, including self-administered surveys, studies in vitro, and studies in situ that have shown sports energy drinks cause dental erosion, leading to permanent loss of tooth volume and a softening of the outer layer of the tooth.


The Relationship Between Periodontitis And Cardiovascular Disease, Jonathan Krupka Jan 2017

The Relationship Between Periodontitis And Cardiovascular Disease, Jonathan Krupka

The Science Journal of the Lander College of Arts and Sciences

The relationship between periodontal disease and cardiovascular disease has been the subject of much research in recent years. The aim of this study is to review and analyze the relevant literature regarding this relationship, with an emphasis on determining a presence of periodontal bacteria from the periodontal pocket in atheromatous plaques, and to explore the biological role of inflammatory mechanisms that may link periodontitis and cardiovascular disease. Although there seems to be conflicting reports, the overall consensus confirms the presence of periodontal bacteria, such as Porphyromonas gingivalis, in atheromatous plaques. Additionally, the presence of systemic markers of cardiovascular disease in …


Is Tooth Bleaching Really Safe?, Yehoshua Krasnow Jan 2017

Is Tooth Bleaching Really Safe?, Yehoshua Krasnow

The Science Journal of the Lander College of Arts and Sciences

The field of cosmetic dentistry emerged when people began to realize the importance of a good smile. Stains on teeth were no longer deemed acceptable with the advent of cheap and safe procedures like tooth bleaching. This new procedure replaced the older, more costly and invasive method of laminated veneers and crowns. The chemistry behind this bleaching occurs via unstable hydroxyl radicals and thus the question arose as to how safe this accepted procedure really is. The purpose of this paper is to analyze the negative ramifications of tooth bleaching and to determine if it’s truly safe. The null hypothesis …


Using Dental Stem Cells To Regenerate Tooth Tissue And Whole Tooth Replacement, Peretz Rapoport Jan 2017

Using Dental Stem Cells To Regenerate Tooth Tissue And Whole Tooth Replacement, Peretz Rapoport

The Science Journal of the Lander College of Arts and Sciences

Irreversible dental problems such as dental carries and periodontal disease create a plethora of general and oral health issues. Although there are solutions to treat these different problems, an emphasis has been placed on finding a solution to these points with the help of bioengineering and stem cells. Using stem cells to treat these problems could result in a more permanent fix than the methods dentists employ now. Two novel approaches to fixing irreversible dental problems via stem cell therapy are tooth tissue regeneration and whole tooth replacement. This paper reviews the advantages and disadvantages of using dental pulp stem …

The Role Of Streptococcus Mutans In The Formation Of Dental Caries: An Ecological Perspective, Jason Yeshaya Friedman

The Science Journal of the Lander College of Arts and Sciences

The teeth are among the most distinctive and productive features of the human species. It is the longest lasting surface of the body and can be used in research studies many years after death. Yet, in the living individual, the integrity of the teeth is constantly assaulted by a microbial challenge so great that dental caries, or decay, ranks as one of the most widespread medical afflictions. According to studies, dental caries rank third in medical costs, behind only heart disease and cancer (Loesche 1996). This review will attempt to describe what is responsible for dental caries, namely a bacterium …
