Corrosion Of Implant Materials In The Human Body, Maedeh Barzmehri

Corrosion Research

This paper extensively examines the complex problem of implant corrosion occurring within the human body. The corrosion of implants gives rise to substantial challenges, encompassing compromised implant durability, patient safety concerns, and potential adverse impacts on the long-term functionality of the medical device. The study's primary objectives include offering a concise overview of the various corrosion mechanisms that impact a range of implant materials and outlining health complications linked to the byproducts of implant corrosion. Furthermore, it delves into a cost analysis specific to hip or knee revision arthroplasty, which has become a prevalent scenario in implant failure cases on …

Acceptability Of Fully Guided Virtual Implant Planning Software Among Dental Undergraduate Students, Shishir Ram Shetty, Colin Murray, Sausan Al Kawas, Sara Jaser, Wael Talaat, Medhini Madi, Vinayak Kamath, Nisha Manila, Raghavendra Shetty, Vidya Ajila

School of Dentistry Faculty Publications

Background: Fully guided implant surgery as a technique is gaining popularity. It has been observed that use of surgical guides improves precision and predictability for dental implant placement. However, like any other newer technology, the acceptance of fully guided dental implant technology among users is based upon its perceived usability. This study aimed at evaluating the perception about using Virtual Implant Planning Software (VIPS) among undergraduate dental students at the university of Sharjah. Methods: Ninety-Six dental surgery students from the University of Sharjah were included in the study. One week after the Virtual Implant Planning Software (Planmeca Romexis version 6.2 …

Sfd Indications And Technique: When And How To Use Sdf To Manage Caries Lesions, Margherita Fontana Dds, Phd

The Journal of the Michigan Dental Association

The aim of this article is to review indications for 38% SDF and the appropriate technique for use. Evidence-based recommendations by the American Dental Association and umbrella reviews of systematic reviews are summarized to provide indications for SDF use in primary and permanent teeth, including sound surfaces and those with non-cavitated and cavitated caries lesions. High-quality evidence supports that SDF is an effective treatment alternative for managing active cavitated coronal and root caries lesions and preventing root caries lesions. Dentists can help by incorporating SDF as an option into their caries prevention and management armamentarium and by helping to train …

Too Much Of A Good Thing: Case Of Fluoride Toxicity, Swet Patel, John Polunin, James Espinosa, Alan Lucerna, Trent Malcolm

Rowan-Virtua Research Day

Overall, the beneficial role of fluoride for the maintenance of proper dental hygiene has been known for many decades which has been corroborated by a plethora of research. Media and culture have further highlighted how using fluoride supplementation can help with dental cavities. It is clear that just as there are benefits to fluoride usage, there also risks. Further awareness needs to be made that showcases the downfalls of excess fluoride use. Labels need to be placed on fluoride products that emphasizes the dosing. It is imperative that people are educated on the toxicity of fluoride as too much of …

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 …

Determination Of Dioctyl Phthalate (Dehp) Concentration In Polyvinyl Chloride (Pvc) Plastic Parts Of Toothbrushes, Ghazal Sadeghi, Elham Ghaderian, Anne O'Connor

The Downtown Review

Phthalates are chemicals that are widely used in daily products and polyvinyl chloride (PVC) plastics, mainly because of their ability to enhance flexibility and durability. The presence of phthalates in various products contributes to the substantial exposure that all consumers may experience. Continuity in phthalate exposure has several side effects, including endocrine disruption, neurological damage, asthma, hormonal imbalances, obesity, infertility, genital defects, and testicular cancer. The purpose of this research experiment was to determine the Dioctyl phthalate (DEHP) concentration of PVC plastic parts of toothbrushes. The method used to conduct the experiment was Gas Chromatography/Mass Spectrometry. The result showed that …

Bioerodible Calcium Sulfate Bone Grafting Substitutes With Tailored Drug Delivery Capabilities, Bryan R. Orellana

Theses and Dissertations--Biomedical Engineering

Bone regeneration or augmentation is often required prior to or concomitant with implant placement. With the limitations of many existing technologies, a biologically compatible synthetic bone grafting substitute that is osteogenic, bioerodible, and provides spacing-making functionality while acting as a drug delivery vehicle for bioactive molecules could provide an alternative to ‘gold standard’ techniques.

In the first part of this work, calcium sulfate (CS) space-making synthetic bone grafts with uniformly embedded poly(β-amino ester) (PBAE) biodegradable hydrogel particles was developed to allow controlled release of bioactive agents. The embedded gel particles’ influence on the physical and chemical characteristics of CS was …

Frictional Forces Of A Fixed, Esthetic Orthodontic Appliance System, Brady Michael Nance

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: The demands of an all esthetic fixed orthodontic appliance system are ever increasing in today's world. Frictional values of an esthetic, fixed orthodontic appliance system are needed to evaluate their clinical effectiveness for orthodontic treatment. The aim of this study is to evaluate the frictional values of various esthetic orthodontic archwires ligated to an esthetic orthodontic bracket.

Methods: Three types of stainless steel and nickel titanium alloy (niti) esthetic orthodontic archwires (epoxy, poly, plastic) in four sizes (.016, .018, .017 x .025, .019 x .025 inches) were ligated to both a stainless steel bracket system and a ceramic (esthetic) …
