eflected in urinary values).3 Conrad Howe, Balraj Kang, Julie Kim, Brittany Kraft, Kevin Kurtzner, Michael Kutsyk “Is BPA a concern for dentistry?” Bisphenol A (BPA) is a synthetic compound used worldwide in the manufacturing of plastics and epoxy resins. Derivatives of BPA are present in resin-based sealants and composites used in dentistry.1 Some of these compounds include bis-DMA (BPA dimethacrylate), bis-GMA (BPA glycidyl methacrylate) and BADGE (BPA diglycidylether).1 Although pure BPA is not utilized in dental resins, it has been demonstrated that bis-DMA has the ability to be hydrolyzed into BPA by salivary esterases.1 This is a potential cause for concern due to the many adverse health effects associated with BPA. These effects are presumably due to the ability of BPA to bind to nuclear estrogen receptors and interfere with endocrine signaling.1 Thus, it is of interest to determine the estrogenic potential of dental resins over time. A study done at the Institute of Biomaterials and Bioengineering in Tokyo analyzed BPA release from orthodontic brackets submerged in water. ...
Professionalism in the dental profession refers to our responsibilities and obligations that exists throughout our entire dental career. “Professional competence is the habitual and judicious use of communication, knowledge, technical skills, clinical reasoning, emotions, values and reflection in daily practice for the benefit of the individual and community being served (Kirk, 2007).” A health professional must be able to regulate their own behavior and comply with a code of ethics in professional practice. Fundamental principles of professionalism include primacy of patient welfare, social justice and patient autonomy (Kirk, 2007).
I am currently studying at CFCC to get into the Dental Assisting program. Upon graduating, I would like to acquire a job at an orthodontists office. The employment for this occupation is actually expected to grow much faster than average; between 2008 and 2018, employment is expected to grow 36 percent. The job demand in the Cape Fear area seems to be fairly higher than other areas in North Carolina, and higher than some other states as well.

The contraction moulding method can be used to process an acrylic denture base. In this method, bite blocks are fabricated in the lab and sent to the clinic for patient trial. These are then received from the clinic and teeth are mounted onto the bite blocks. The wax is eliminated and teeth are pressurized and attached onto a gypsum mould. (McCabe and Walls. 2008.) Sodium alginate is applied onto the mould to act as a separator to prevent any monomer from the acrylic base seeping into the base and the mould. Acrylic PMMA is applied onto the mould and either heat-cured or auto-polymerized. Both of these curing methods form the...
During recent years, numerous newspaper and magazine articles have suggested that humans may be at risk because small amounts of well known environmental contaminants, such as dioxin, PCBs and DDT, can affect hormone levels. Hormones are produced by the endocrine system as regulators of biological function in target organs. Because hormones play a critical role in early development, toxicological effects on the endocrine system often have an impact on the reproductive system. The term endocrine disruptor is used to describe chemicals that can mimic hormones and may either enhance or counteract their effects. It has been suggested that these hormone changes can, in turn, lead to a variety of health problems including cancer, decreased fertility, and abnormalities in newborns.

I decided to do my research report on dentistry because it is a perfect blend of science and art. It is a science in that you must fully comprehend on the different types of diagnostic and procedures you are doing. It is an art in that you are constantly working with your hands to create a beautiful smile. The impact you make on helping a person achieve an impeccable smile is not one to compare with materialistic things like money or cars. People often mistake dentist as only doing practices when in fact they could do more, like research. I was fortunate enough to have been given the opportunity to interview Dr. Sarah Pham, DDS, a close family friend who practices dentistry in her own private office in Los Angeles, California. Dr. Pham was
o Please describe a time when you performed a thorough head, neck and oral exam and the findings had a significant impact on how you proceeded with the dental hygiene process of care. Annette was performing her usual head, neck, and oral exam on a patient and found an enlarged thyroid. She recommended to the patient that she go see her primary care physician to get a better diagnosis. The patient went to her primary care physician and was told there was probably nothing. Later, the patient returned to the dental office and saw Annette and told her what the physician said.
In the Dental Hygiene field, many challenges come about every day and during different situations. Every day there are new challenges and unusual situations that occur in the dental field, but one challenge that continues to come about and has been a big dispute over the years is the ability to provide beneficial information about oral health care for the underprivileged. For the individuals that are not fortunate enough to pay to have services done in the dental office, lack the knowledge of how important good oral health care is. They do not receive the one on one conversations explaining the significance of taking care of your teeth and gums that the patients who can afford to make appointments and receive essential services do. That
The US Container Recycling Institute estimates that 67 million plastic water bottles are discarded every day, which is enough to wrap around the planet 149 times each year. Therefore, plastic water bottles should be banned from public use. The usage of water bottles should be suppressed because they are incredibly dangerous, wasteful, expensive, and rarely recycled. Researchers have stated that plastic bottles containing water can contain many harmful chemicals. After close examination of the plastic, researchers have concluded that some plastics contain chemicals, such as phthalates, bisphenol A (BPA), endocrine disruptors, and carcinogens, which may leach into the water, especially after being stagnant for long periods of time.
Bisphenol-A (BPA) is all around us: in food containers, toys, baby bottles, dental products, CD/DVD discs, water bottles, register receipts, fax reports, newspapers, toilet paper and cereal boxes. BPA can cause cancer, behavioral problems, diabetes, ADHD and many other hormonal issues. 1 There is an increased risk of developing behavior problems when one is exposed to BPA at an early stage of life. As a parent, I am concerned about my children’s exposure to BPA. We tend to use plastic frequently as glass can break easily which is not safe for the children. Disposable containers and packaged food are convenient and readily available. 1 I searched on PubMed and Google scholar for peer reviewed articles related to BPA and its effects on children. The focus of this article will be to discuss some of the sources of BPA which children encounter and some examples of health risks children face due to BPA in the environment.
An example of an additive is di-butyl phthalate and biphenyl A (BPA), these substances are incorporated while the plastics are being manufactured to provide tensile flexibility and tensile strength. The microplastics tend to accumulate and adsorb toxic materials from the seawater around them, such as organic pollutants and heavy metals. The chemicals are not bound to the microplastic surface, and as a result, when ingested they tend to leach into the animal tissues (Do Sul, J. A. I, 2014). The impacts from such chemical leaches include hepatic stress in fish, mortality, and endocrine
The topic of endocrine disruption, and the potential consequences for human health, is a popular area of investigation for many scientific researchers. Endocrine disrupting chemicals (EDCs) are compounds that have the capability of modifying hormone signaling while possibly effecting the development of both the nervous and reproductive systems, as well as enabling the development of cancer (Site 1). Of all the possible EDCs, phthalates seem to be one of the best-studied and most habitually encountered EDC. According to a study that investigated EDCs and asthma-associated chemicals in consumer products, phthalates are commonly used as solvents in personal care products, adhesives, detergents, lubricants, as well as pesticides despite the short
