Dental amalgam is a material which is commonly used to fill cavities. This type of filling is also known as silver fillings. There have been many questions raised due to the use of this form of filling. This is due to the fact that dental amalgam is made up of a mixture of metals. These metals consist of liquid mercury and a powdered alloy that is made up of elements such as silver, tin, and copper. The reason why the use of this filling is so controversial is due to the fact that about 50% of dental amalgam is mercury. High amounts of mercury exposure are known to be toxic in humans. One would naturally wonder why this would be a controversial topic. One would think if it is toxic to humans why use it? Well there are reasons for this, and this is because unlike other types of mercury metallic mercury is considered non-toxic. Swallowing metallic mercury causes no type of poisoning or any harm to the human body. However, it is a proven fact that breathing in large quantities of metallic mercury vapor can cause a serious amount of poisoning. Metallic mercury vapors can be absorbed into the bloodstream almost instantly. In dental amalgam large quantities of mercury vapor are not being poured into the lungs, it is actually a …show more content…
Its advantages consist of the fact that they bond chemically to teeth, making it much easier to insert. Another advantage is from its constant release of fluoride into the mouth, which in turn reduces the chances of tooth decay. It is also a very good adhesive in the sense that it is very efficient when it comes to permanently cementing crowns, bridges, etc. The disadvantages of glass Ionomer cement fillings are actually a step down from composite fillings. For example, they are not as strong as composite fillings, nor are they less expensive than composite fillings. Another disadvantage is its ability to wear and they are also prone to
In comparing micro-leakage of resin-modified glass-ionomers (RMGI), flowable composite liners, and no liners, it was found that by applying a RMGI liner before placing the composite decreased the extent of micro-leakage3. By doing this, the farthest the micro-leakage occurred was to the cervical wall, whereas with composite liners and no liners there was leakage to the cervical wall and into the axial wall3. The reason for the difference could be attributed to the bond between the glass ionomer and composite. This bond is weak and can be thought of as an unbounded wall, leading to less shrinkage stress to the bonds between composite and dentin3.
Pit and fissure sealants are tooth coloured materials that are applied on the occlusal surfaces of the posterior teeth in deep grooves, pits and fissures. They protect the tooth from various bacterial plaques in these caries prone areas of the teeth. The sealants protect these areas by sealing of the entrance to bacteria which give rise to dental caries in susceptible individuals especially in children. Pit and fissure sealants are now commonly being used due to the increase in the awareness among public about dental caries prevention

Dental carries is one of the most common oral diseases in the world, and it often goes untreated due to the expense of treatment. According to the World Health Organization (WHO) 60 to 90 percent of school aged children throughout the world suffer from untreated dental carries. Ethnic minorities, the poor, the elderly, and those who are mentally and/or physically disabled are other disparities who also suffer from untreated dental caries (Alcorn & Rogo; 2012). Looking for a way to solve the epidemic of dental caries by providing affordable treatment, silver diamine fluoride (SDF), also known as the “silver fluoride bullet,” was created. Claiming to be both affordable and effective, SDF could be the answer to low cost carries treatment the world has been searching for. The purpose of this paper is to research the efficacy of silver diamine fluoride in comparison to sodium fluoride varnish. Our PICO question is: In a patient with dentinal caries, will the use of silver diamine fluoride compared to sodium fluoride varnish, be more effective at arresting caries?
Fluoride added in our waters would also add other toxics that we may not know about. “The CDC admits that that 43% of fluoridation chemicals tested from contain arsenic, 2% contain lead and 3% contain copper” (12 Reasons). How is that supposed to help our bodies or decrease tooth decay? Scientist say, that the level of them are too low to do any damage to our bodies. The Environmental Protection Agency however, states that arsenic and lead have incre...
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...

Picture yourself with a toothache or someone with poor hygiene and knowing you cannot do anything to change it without a dentist. A dentist is specialized individual that treats the diseases and conditions that affect the oral cavity.
The existence of micro-leakage in dental restorations was first identified in scientific research in 19126. In a study done by Harper (1912), air pressure was used to penetrate the surface between an amalgam restoration and cavity preparation7. By applying pressure through a hole in the pulpal floor, Harper could quantify the amount of pressure needed to establish leakage through the emergence of bubbles from the margins of the restoration. Research has come a long way since Harper first recognized micro-leakage. Adaptations of new materials used when placing composite restorations like BondAband, a light-cured glass-ionomer cement has been shown to reduce marginal micro-leakage in posterior restorations8. A decrease in microleakage has also been shown with the use of an ...
Almost everyone chews a piece of gum in his lifetime. According to consultingcase101.com, seventy five percent of kids and teenagers between the ages of eight and fifteen chew gum. Of the people that chew gum, they average about two sticks per day. This is just in the United States alone. People should really pay attention to what they are putting into their mouths and digestive systems when they chew gum. This paper's purpose is to reveal the secrets behind gum manufacturing.
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
This is a strong neurotoxic which it lethal if people absorb 0.2-0.4 grams into their body. The acute poisoning person see loss of appetite, need more water, salivation, vomiting, bloody and diarrhea, eye inflammation, gait instability, and other performances. It will cause by sudden death is mainly due to cardiac conduction system and spinal cord damage, and it also caused acute kidney failure(Basic). The propose of industries using mercury in mascara that they mixed mercury with chlorine, and get the production HgCl, this element can use as preservative, in order to extend the expire the day of the product. More importantly, mascara is used near the eyes, and eyes have the closest nerval connect with brand, which means mercury can easily go into people’s brand by blood circulation and causes irreversible damage, such as nervous prostration, increase violent tendencies and reducing IQ. In addition, by the time people absorbed mercury into body by whatever accident, mercury will stay in their body forever, there is no way to get rid of the mercury from inside of human’s body so far. Even though, mercury only take a little weight overall the ingredient, probably like 1/10000 grams in entire mascara. However, the potential damage of mercury bring to people cannot be ignored or avoided. Moreover, the worker is the biggest victim for those manufacturing that extract the mercury. Mercury only can extract by
Impression materials are used to register or reproduce the form and relations of the teeth and the surrounding oral tissues (1). Making an impression represents a critical step in processing and fitting of a dental prosthesis (2). Several types of impression materials are produced. These include silicones, polyether, polysulfide and alginate which are available for crowns and fixed partial denture impressions. Silicone impression materials are considered to be suitable impression materials to use for fixed prostheses (3). Also, it has been reported that silicone has the ability to remain dimensionally stable through disinfection procedures (4). Among silicone impression materials, one type of them, called polyvinyl siloxane (PVS) is reported
Dental treatments including fillings, root canals, and bridgework can contribute to disease. Moreover, the utilization of hazardous materials
Growing up I heard many stories from my peers of their experiences at the dentist’s office. It is upsetting to say that most of my visits were vividly terrifying. As a child, the grinding, scratching, and high-pitched twangs of the instruments digging around in my mouth would leave my ears ringing and teeth vibrating every single time. The smell of fluoride and disinfectants permanently infected the air, sending chills through my body the minute I walked in. I quickly learned that latex posses an extremely unappetizing aftertaste. Needless to say, I was not always enthusiastic about going to the dentist’s office and getting braces did not make anything better for me.
