Future Dental Journal

Purpose: To assess the effect of aging and various surface treatments on the microtensile bond strength of resin cement to two hybrid esthetic materials. Materials and Methods: Zirconia-reinforced lithium silicate (Celtra Duo, Dentsply Sirona, United States) and hybrid resin nanoceramic (Cerasmart TM, GC Corporation, Japan) blocks were cut into plates of 3 mm thickness. Each ceramic material was surface treated either with hydrofluoric acid etching and silane or with sandblasting and silane. A dual-cured adhesive resin cement (Panavia TM V5, Kuraray, U.S.A.) was utilized to bond the composite resin plates to the surface treated ceramic plates. The ceramic-composite resin blocks …

Biofilm Forming Ability Of Bacteria Isolated From Dental Caries: With Reference To Streptococcus Species, Sonali Kaustubh Ambulkar, Vidya Tale, Abhijit Jadhav, Komal Kulkarni

Future Dental Journal

Dental caries is formed by the group of microorganisms attached to a tooth surface embedded in a matrix of polymers. Biofilm plays an important role in the development of dental caries, plaque and other periodontal diseases. The present study is aimed to isolate, identify and characterize bacteria from dental caries. The ability of biofilm formation of these isolates was confirmed by Congo red agar method, Tube method and Microtitre plate method. High biofilm-forming bacteria were identified by 16S rRNA sequencing. Streptococcus mutans, Streptococcus anginosus, Enterococcus faecalis and Rothia dentocariosa are the predominant biofilm forming bacteria associated with dental caries.

Using Cold Plasma As A Surface Treatment With Peek Dental Implant: A Case Series”., Mohamed Dohiem, Hebatalla Mahmoud El Afandy

Future Dental Journal

Background: Polyetheretherketone (PEEK) is a material that can be used instead of normal titanium implants. PEEK is considered inert and biocompatible, however, it has been shown to possess low surface energy and that leads to decreased osteointegration with bone, Recent researches have focused on increasing the bioactivity of PEEK by modifying the surface by chemical and physical means such as plasma treated surfaces.

The Purpose of this article to evaluate peek dental implant with cold plasma surface treatment

Materials In this case series an immediately loaded peek dental implant, treated with plasma surface activation method, was used to replace anterior …

Expression Of Mir-720 Is Correlated With Dnmt3 In Oral Squamous Cell Carcinomas, Andrew Graves, Sukhdeep Sandhu, Karl Kingsley

Dental Medicine Faculty Research

Background: Many factors are involved with cellular differentiation and pluripotency, such as long non-coding and microRNAs (miRNA). miR-720 has been demonstrated to affect development, differentiation and pluripotency in dental pulp stem cells but has also been linked to many cancers (renal, prostate, skin, colorectal, breast, cervical and esophageal) through shared pathways including DNA methyltransferase family members (DNMT)3a and DNMT3b, which are highly upregulated in many oral cancers. However, little is known about the expression (or function, if expressed) of miR-720 in oral cancers. Based upon this lack of information, the primary objective of this project was to evaluate the expression …

Improving Dental Hygiene Students' Journal Writing, Susan Davide

Publications and Research

During the introductory semester of treating patients, students are in need of assistance and guidance throughout the assessment and treatment phases of patient care. As novice learners, there is little to no prior knowledge on writing a patient case study presentation. To assist and improve dental hygiene student writing of patient case journals, a scaffold assignment was created. Over the course of the semester students were required to submit five patient case studies in the form of a journal. Each journal had a writing focus with specific directions for each along with a detailed rubric; the final journal encompassing all …

Evaluation Of Mechanical And Biocompatibility Properties Of Hydroxyapatite/Manganese Dioxide Nanocomposite Scaffolds For Bone Tissue Engineering Application, Fatemeh Azizi, Fatemeh Heidari, Farahnaz Fahimipour, Mohammad Sajjadnejad, Daryoosh Vashaee, Lobat Tayebi

School of Dentistry Faculty Research and Publications

The aim of this research was to evaluate the mechanical properties, biocompatibility, and degradation behavior of scaffolds made of pure hydroxyapatite (HA) and HA‐modified by MnO₂ for bone tissue engineering applications. HA and MnO₂ were developed using sol‐gel and precipitation methods, respectively. The scaffolds properties were characterized using X‐ray diffraction (XRD), Fourier transform spectroscopy (FTIR), scanning electron microcopy (SEM), energy dispersive spectroscopy (EDS), and transmission electron microscopy (TEM). The interaction of scaffold with cells was assessed using in vitro cell proliferation and alkaline phosphatase (ALP) assays. The obtained results indicate that the HA/ MnO₂ scaffolds possess higher …

School of Dentistry Faculty Research and Publications

Magnetic dual-template molecularly imprinted polymer (Fe₃O₄@SiO₂-MDMIP) was prepared to enrich and determine both p-Coumaric acid (p-CA) and ferulic acid (FA) based on syringe-to-syringe magnetic solid-phase microextraction (SS-MSPME). The obtained MDMIP was characterized and recognized, and then its adsorbing performance was studied. Based on the results, the Fe₃O₄@SiO₂-MDMIP indicated selective recognition towards p-CA and FA with large adsorption capacity. The optimization of MDMIP–SS-MSPME conditions (pH, Fe₃O₄@SiO₂-MDMIP mass, NaCl concentration, number of cycle, and elution volume) were conducted using the central composite design (CCD). …

Effect Of Nanofiller Coating And Loading On Facial Elastomer Physical Properties, Rahmi K. Aulia

Theses & Dissertations

Current materials used for facial prostheses are far from being desirable, and improved properties with “skin-like” feel are needed. This study evaluates property changes induced by sequential additions of uncoated and hydrophobic-coated nano-SiO₂ to polydimethylsiloxane (PDMS) and compares them with those measured for conventional submicron SiO₂-filled materials. Each filler type was sequentially added to vinyl-terminated PDMS at 0%, 0.5%, 5%, 10%, and 15% by weight. Tensile, tear, Durometer hardness, translucency and viscoelastic properties were evaluated, with hardness and translucency also evaluated following 3000 hours of outdoor weathering. Results demonstrated that 15% coated nano-SiO₂-filled PDMS materials …
