The Effect Of Artificial Aging And Surface Treatments On Microtensile Bond Strength Of Resin Cement To Hybrid Ceramics, Engy I. Hassan Shohdy, Shereen A. Nossair, Amina M. Hamdy

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 …

Journal of Dentistry Indonesia

Nanotechnology is a branch of science focusing on the manipulation of materials measured on the nanoscale (size = 1–100 nm). Recent advances in the field of nanodentistry have resulted in the development of alternative treatment plans for common dental problems, bringing about a paradigm shift in dentistry. Nanorobots, also known as “nanites” or “nanomachines,” are theoretical microscopic devices that may be used for the diagnosis and treatment of oral health problems. This paper aims to discuss the latest innovations in the field of nanodentistry.

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 …

Antibacterial Efficacy Of Novel Eastern Medicine-Inspired Toothpastes Compared To Commercial Formulations, Joshua S. Goldfaden

Pacific Journal of Health

Toothpaste is an oral health care agent that dates back to the 5^th Century B.C. in East Asia. Following the conception of dentistry in the 7^th Century B.C. and the field’s subsequent growth, the embodiment of toothpaste has evolved from containing natural substances such as tea leaves to abrasive chemicals, particularly: fluoride, triclosan, and sodium lauryl sulfate (SLS). Regarding how each respective reagent functions, fluoride forms a complex with calcium ions in the teeth to prevent erosion of the protective enamel coating. This ion also disrupts metabolic activities of Streptococcus mutans (S. mutans), which are the …

Replacing A Single Tooth: Single Implant Vs. Three Unit Bridge, Ibeth Erazo, Aneeza Hussain

Publications and Research

There are more than two options for restoring a single tooth but our research includes a three-unit bridge and a single-tooth implant as the main options. In this paper, we discuss the advantages and disadvantages of these methods and the factors that must be considered when choosing between them for the replacement of a single tooth. Although in some cases a three-unit bridge is the most appropriate choice, implants have the advantage of allowing preservation of the integrity of sound teeth adjacent to the edentulous area. Many factors must be considered when choosing between a three-unit bridge and an implant …

Journal of Dentistry Indonesia

The number of people living with HIV (PLHIV) has been increasing since the first known case in the early 1980s. However, PLHIV can also experience comorbidities, such as health anxiety. In the oral cavity, anxiety is often associated with the etiology of parafunctional habits. Anxiety can be measured using self-administered instruments, such as the Hospital Anxiety and Depression Scale (HADS) and Short-Health Anxiety Inventory (SHAI), which is specifically used in the medical setting. Objectives: We are describing a case of HIV positive patient with health anxiety who presented to the oral medicine clinic in our hospital with a complaint of …

Differential Diagnosis And Histopathological Analysis Of Localized Gingival Overgrowths: Study Of 218 Cases From Northeast Thailand, Lordjie Marr Morilla, Ajiravudh Subarnbhesaj, Poramaporn Klanrit

Journal of Dentistry Indonesia

Localized gingival overgrowths (LGOs) are relatively common clinical findings. These lesions can be associated with chronic irritation, infections, or they can represent benign or malignant tumors that can either be primary or metastatic. The etiology of these lesions is multifactorial, but the most prevalent cause is reactive hyperplasia and inflammation induced by dental plaque. Objective: This study presents the prevalence of LGOs in Northeast Thailand and identifies the most common LGOs in the region. Methods: A series of 218 LGO cases was studied. Results: Pyogenic granuloma (PG), gingival squamous cell carcinoma (GSCC), and peripheral ossifying fibroma (POF) were the three …

Comprehensive Review Of Current Endodontic Sealers, Takashi Komabayashi, David Colmenar, Nicholas Cvach, Aparna Bhat, Carolyn Primus, Yohji Imai

Dental Medicine Faculty Publications

Endodontic sealers for non-surgical root canal treatment (NSRCT) span many compositions and attributes. This comprehensive review discusses current types of endodontic sealers by their setting reaction type, composition, and properties: zinc oxide-eugenol, salicylate, fatty acid, glass ionomer, silicone, epoxy resin, tricalcium silicate, and methacrylate resin sealers. Setting time, solubility, sealing ability, antimicrobial, biocompatibility, and cytotoxicity are all aspects key to the performance of endodontic sealers. Because sealing ability is so important to successful outcomes, the relative degree of microleakage among all the relevant sealers was calculated by way of a meta-analysis of relevant literature. Compared to AH Plus, tricalcium silicate …

Three Dimensional Biometric Guide In Determining Maxillary Tooth Position And Arch Form, Tawfiq Omar Farouq

Student Works (2020-2029)

In complete denture fabrication, when pre-extraction records are lacking, determining the denture teeth positions to where the natural predecessors occupied is essential yet challenging. Although several biometric guides were suggested to position teeth for dentures, none is providing three-dimensional (3D) positions of teeth that can be used in the recently developed computer designed digital dentures. The aim of this study was to develop new biometric guides to determine the original 3D positions of the maxillary teeth and dental arch form individualised for each given dentate or edentulous maxillary cast based on selected intraoral landmarks. The objectives were to investigate the …

Investigation Of Inflammatory Responses Following The Use Of Novel Anisotropic Hydrogel Tissue Expander In The Skin Of Maxillofacial Region, Salim Igdayir Kholoud Mohamed Ali

Student Works (2020-2029)

Background: The purpose of tissue expander is to grow healthy supplementary tissue under the controlled of mechanical force exerted by the tissue expander. In the field of reconstructive and plastic surgery, the use of soft tissue expanders are important for growing healthy supplementary tissue. However, the molecular mechanism associated with the inflammatory response associated with the force generated from the use of tissue expanders is still not characterized. Among the many types of tissue expanders, anisotropic type of hydrogel tissue expander was chosen due to its ability to produce controlled incremental inflation on the tissue that enhance cellular adaptation and …
