Dental amalgams are a great material that provided major leaps in the world of dentistry. While being such a major advance they have also became an issue of great debate. The mercury in dental fillings has been thought to cause central nervous system complications, an overall diminished well-being in some patients, and Alzheimer. The dental field should incorporate safer filling materials for patients. In this article we will take a look at the history of the silver amalgam and view both the negative and null views of this issue.
Throughout the history of dental medicine dentist have searched for the perfect material to aid in the treatment of the most common problem in people’s mouths, cavities. The material would also be useful in fixing chipped and broken teeth. Dentist needed a material that was strong, relatively low costing, easy to apply, durable, and able to limit the growth of bacteria. In the early 19th century in France dentist found their wonder material and that material was amalgam. The dental amalgam is constructed of a mixture of mercury and at least one other metal such as zinc, copper, tin, or silver. The combinations of these metals are the foundation of what gives silver amalgams their strong make up and shiny metallic appearance.
The earliest use of amalgams in dentistry is still quite unknown to researchers but there are claims that it may have been dated as far back as 659 A.D. in China. Before the discovery of the amalgam dentist tried all types of material to help in the restoration of teeth. Stone chips, resin, cork, gum, turpentine, lead, and gold were some of the early materials that were boiled up and poured on teeth to create fillings. A dentist by the name of Louis Regnart had the brilliant idea t...

Frank. On March 1, 1872, the Pennsylvania College of Dental Surgery in Philadelphia conferred the degree of Doctor of Dental Surgery upon twenty-six men, one of whom was John Henry Holliday. Upon completion of his training and graduation, Dr. Holliday opened an office with a Dr. Arthur C.
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
* A small amount of mercury is found in the crust of the earth. This is not the problem. The anthropogenic mercury is the problem.
The loss of his mother and is devotion to education spurred him to peruse a degree in dentistry. In 1870 Holliday moved to Philadelphia to attend the University of Philadelphia Dental School. During his studying he wrote his thesis on the “disease of the Teeth”. His mentor during school Lucian Frink who practiced dentistry in Valdosta, Georgia between 1868 until 1879, Holliday attempted to gain the most information possible. At the University of
3) Describe the rationale and demonstrate how to chart existing restorations (amalgam, composite, gold, crowns, bridges, other), missing teeth, incipient caries and caries.
The variety of dental instruments that have been invented since the beginning of basic dentistry till modern times is enormous. Dentistry has been around since the Ancient Egyptians, the firsts known dentist was Hesy-Re, who has inscribed on one of his tomb walls “the greatest of those who deal with teeth”. Onward from Hesy-Re, the focus on dental health became a concern, however, it was not till about the end of the 1700’s that dentistry was regarded as true profession. Dentistry during the American Civil War was not the initial interest of the time, the focus was of course on the injured men who would come off the battle field. When one thinks of Civil War medicine they may tend to think of amputations and treating bullet wounds. However,
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 has been established for many years as an effective ingredient in the fight against caries. Silver has been used in health care as an anti-bacterial agent in many medical applications such as silver sutures and silver catheters. Silver diamine fluoride was created to increase the effectiveness of both.
After the treatment and procedure is complete, patients leave with healthier, more beautiful teeth, giving them the confidence to ask someone out on a date or the confidence to smile on an important job interview. Dentistry is and has been for centuries, an important aspect of people’s ...
Knowing the origins of career is key to understanding the importance of why it began. According to the American Dental Association (ADA), dentistry's ancient origins began in 500 B.C. with the belief of "tooth worms as the cause of teeth decay." Later down the road in 1700 – 1550 B.C., an Egyptian text reveals toothache remedies. Oral cavity issues were provident in a very early time of humanity. As a result, oral cavity issues continued therefore so did research which inspired Hippocrates and Aristotle to write
Denture teeth can be made of acrylic poly(methyl methacrylate) (PMMA) or composite resins. PMMA is a polymer - a material made the from joining of methyl methacrylate monomers. Properties of PMMA include resistance to abrasion, chemical stability and a high boiling point. (Jun Shen et al. 2011). However, weak flexure and impact strength of PMMA are of concern as they account for denture failure. (Bolayir G, Boztug A and Soygun K. 2013). Composite denture teeth are made of a three distinct phases - filler, matrix and coupling agents. Out of the types of composite teeth available, nano-filled composite teeth are preferred. Composite teeth have a PMMA coating around the tooth and a high content of filler particles. This gives them strength, higher resistance to forces than acrylic teeth and provides compete polymerization due to the PMMA coating. (Anusavice, K. J., Phillips, R. W., Shen, C., & Rawls, H. R, 2012). If the interface between the PMMA denture base and PMMA or composite teeth was weak, the denture will not be able to sustain occlusal forces, making the base-teeth interface, an entity of significance.

When it comes to products that are being marketed, there are many different brands that are trying to be sold. It is important for the dentist to know which brand is best for the office. Research can be done online. They can compare the uses, advantages, and cost. The main use for composite resin dental materials is for restoring teeth that has been affected by decay and other damages (know your teeth, 2007). Composite resin is different from other dental materials because it is a white filling. It can be matched to the patient’s natural tooth color so the appearance is not an issue. Patients have the option of choosing between non esthetic and esthetic filling. That is why some patients prefer to have composite resin fillings than other dental materials. It is used for cosmetic purposes as well as fixing the decayed teeth. When the patient has a composite filling done, the dentist will place it on the tooth in layers. Most often, a light is used to harden the material. After the layers are in place and it is auto cured by the light, the dentist uses electronic instruments to reshape the tooth. It is important to shape it back as much as possible to the original tooth structure and anatomy....
Our analysis revealed that Affinis® had more dimensional stability in comparison to Panasil® and in the Panasil® impression material, the percentage of dimensional change was significant after 168 h. However, dimensional changes in all of the evaluation times were in the American Dental Association (ADA) standard range. Therefore, these materials had acceptable clinical dimensional stability for approximately 168 h. In the current study, impressions were made from stainless steel dies following the ADA specification for impression materials. This provides a protocol that can be easily replicated by others and it is the same as making a clinical
Nano-technology is a revolution in almost all disciplines of life today. Nanotechnology approaches the manipulation of matter at atomic and molecular level. This technology, which deals with matter in nano-dimensions, has widened our views of poorly understood health issues and provided novel means of diagnosis and treatment. Dentistry, not being an exception, also faces major revolutions to constantly provide better and more comfortable dental care to patients. Researchers in the field of dentistry have explored the potential of nano-particles in existing therapeutic modalities with moderate success. The important application in the field of dentistry
Cosmetic dentistry is a specialized field that deals with improving the aesthetics of teeth and the human face. The teeth are an important part of human beauty. Even minor damage to the teeth, such as breakage or loss can drastically alter the overall appearance of the face. This is where cosmetic dentistry comes in to restore beauty. Cosmetic dentistry has become a highly specialized branch due to various advancements in surgical procedures and diagnostic techniques. Several new materials have also been discovered. These materials are very close to the natural enamel and bone from which teeth are made and are virtually indistinguishable. Cosmetic dentistry is an option in conditions such as teeth loss, gaps between teeth, cracked or chipped teeth, cavities and dental
