Abstract:
The word ‘amalgam’ is derived from a Medieval Latin word ‘amalgama’. It means a combination or mixture of different things. In dentistry, it’s called dental amalgam as it has a combination of metals (mainly Silver, Mercury Tin and Copper). They are commonly known as silver fillings because of their silver-like appearance. (1,2)
It is an excellent tooth filling material which is used to restore decayed teeth. It has been one of the most popular and efficient filling material of choice by the dentists for more than one hundred years around the globe because of its strength, high longevity, ease of use and inexpensive material. (1,2)
Dental amalgam consists of two components: liquid (Mercury) and Powdered alloy (Mixture of Silver tin copper zinc iridium or palladium). Elemental mercury constitutes approx. 50% of the total weight. The chemical reaction allows it to binds all other components together to form a firm, safe and stable mass of filling material and allows it to be easily manipulated into the oral cavity.(1,2)
When the individual is not concerned about the esthetics, dental amalgam can be used in individuals of nearly all ages, stress bearing areas (posterior teeth,) …show more content…

Liquid mercury is mixed with alloy powder to produce a doable mass, by a process called trituration. While, the chemical reaction taken place between the particles of alloy and mercury is known as Amalgamation. Its advantages include: easy to insertion into the oral cavity, high resistance to fracture, prevention from marginal leakage and a relatively long life. The disadvantages of dental amalgam include: conspicuous appearance, high corrosion and galvanism, and brittle nature because metals are a good conductors of heat so there may be a little sensitivity to change in temperature of oral cavity. Despite of its pros and cons, dental amalgam toxicity is still a concern in this modern era.

    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 look at the history of false teeth shows a pain-staking and quirky evolution:

In reviewing these research studies, SDF is an affordable, effaceable alternative to restorative treatment that can be particularly helpful in areas without much dental personal, equipment, or facilities. Further study is needed to determine the recommended interval, exact application, and longer term outcomes. In conclusion, research suggests SDF would be a great carries treatment solution for people around the world, especially those in disparity groups.

    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...

    Abnormal wear of tooth surfaces was an orthodontic problem early on, even ancient people wanted straight teeth! To close gaps, it has been construed that catgut did the work now done by today’s orthodontic wire. In 400-500 BC, Hippocrates and Aristotle both ruminated about ways to level teeth and fix many dental conditions. It should be noted that in Medieval times, expert barbers often performed dental “operations”, extractions, and procedures such as blood-letting. In seventeen twenty-eight, French Dentist Pierre Fauchard published a book called “The Surgeon Dentist” about ways to straighten and align teeth. He used a device called a “Bandeau,” a horse-shaped piece of precious metal which helped...

    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.

  • Dentistry: The Causes and Effects of Micro-Leakage in Posterior Composite Restorations

    1134 Words  | 3 Pages

    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 ...
