quickly. Dental erosion is also commonly referred to as tooth enamel erosion or decay. There are multiple characteristics of humans that can cause dental erosion or speed up the time that it takes for tooth enamel to wear away. Erosion of the enamel is a result of mainly biological factors, chemicals, and behavioral actions (Lussi & Jaeggi, 2008). Many clinicians and researchers have been concerned about the condition of tooth enamel erosion for many years, which led them to discover that dental
The clinical examination of Enamel Hypoplasia: There are two main types of enamel hypoplasia, a hereditary type and an environmental in which both dentitions may be involved. Usually in the heredity type, only the enamel is infected whereas the environmental can affect both enamel and dentin. In mild environmental hypoplasia, few pits, small grooves or fissures are seen on the enamel surface (Fig.1) where in much more severe conditions the enamel may exhibit rows of deep pits arranged horizontally
decorated by four wheel shaped ornaments and two crosses of thin silver, affixed by pins of the same metal, clenched inside. The other articles found in the same situation consists of personal ornaments, the chief of which are two circular enamels upon copper 1 3/4 diameter, in narrow silver frames, and a third, which was so far decomposed as to be irrecoverable; they are enamelled with a yellow interlaced dracontine pattern, intermingled with that peculiar scroll design, visible on the same
In this essay I will discuss the techniques of medieval enamel artist and the how and why a piece was made. In researching the subject of enamelling I became interested in both the Cloisonné and Champlevé techniques. Generally they were the major techniques used by the medieval goldsmith. But as I didn’t want this essay to read like a how to manual I wanted to elaborate on what type of pieces and the reasons why they were made. Enamel has been in use since Mycenean metalworkers first decorated gold
Tooth enamel is a hard mineral substance that covers your teeth. Without this special coating, your teeth will decay and erode. In fact, mineral is found inside your body, especially in your bones. This is the same chemical makeup that you can expect to find in large mammals like whales. If you read on, you’ll find that the main ingredient in mineral is hydroxyapatite, a ceramic biomaterial made of calcium phosphate. Despite the mineralized form of your teeth, you still need to protect your tooth’s
The tooth is the hardest structure in the body, with the strength of enamel exceeding that of bone. If teeth are so tough that they can grind through wood then that begs the question why we keep losing them? It’s nearly inevitable that at some point in life you will lose some of this super tissue just by having a sip on your fizzy. Although it seems that there is a large number of ways for you to lose dental hard tissue, they can be boiled down into to broad mechanisms: Mechanical destruction e.g
Dentinal hypersensitivity is characterized by a short, sharp pain in response to stimuli. Dentinal hypersensitivity, which is more commonly seen in adults in the 20 – 40 – year old age group, has several etiological factors. Gingival recession and enamel loss both contribute to the prevalence of this condition, resulting in the exposure of dentin. Dentinal hypersensitivity is believed to occur due to the movement of fluid within the dentinal tubules occurring in response to: Tactile: Contact with
of enamel without loss of tooth structure Diagnosis: No radiographic abnormalities. Radiographs recommended, especially if other signs or symptoms are present Treatment: Etching and sealing with resin; Smooth sharp edges Follow up: Usually none Enamel fracture Definition: Complete fracture of the enamel with no visible sign of exposed dentin Diagnosis: Clinical - enamel loss is visible Percussion: not tender Mobility: normal Sensitivity: not reliable Radiographic findings: Enamel loss
meets any acids, it reacts with it and calcium acid, phosphoric acid and water will be produced. The acids are fatal to enamel that forms on human’s teeth, and this cause the tooth decay. However when the hydroxyapatite meets fluoride, the single displacement occurs and fluoroapatite (Ca5(PO4)3F) and hydroxide(aqueous) will be produced. This product fluoroapatite can protect enamel from acid attack, which means it fights against the cavity and tooth decay. This is how fluoridation water can help fight
(FluorideAlert). It can be clearly proven that this limits are surpassed daily for the average person and one sign is that more children are being affected by dental fluorosis, a condition that causes white or brown discoloration or spots on the enamel, or tooth surface that only occurs from to much fluoride and this should not be much of surprise if you include the fact that on top of water having anywhere from 0.7-1.4mg of fluoride, toothpaste is 94% fluoride, processed beverages also contain
that are signs of demineralization under an intact enamel. The damage is usually called hypocalcification while the spots are called hypoplasia. Once there are white spots present, this may also indicate a tooth decay or cavity formation has started. What are the causes of white spots on teeth? There are a number of factors why white spots occur and some of these factors are as follows: • Fluorosis. This is a condition which damages the enamel of the tooth primarily because of excessive intake of
The first thing you see when you get into the car, and the last thing you see when you get out. Painting cars is an art, from stock to custom paint there is a lot of possibilities and techniques. Something some people don’t pay attention to and some people its the first thing they look at, and some people make their living by painting cars. In this research paper i will talk about painting and certain various types of custom painting techniques. Painting a car is a good way to make it unique and

Teeth -Chewing on Ice Dear you, here’s the cold truth --chewing ice or ice cubes can do more harm to your pearly whites than good. At first, you may see it as something innocent as drinking water, but really it can cause microscopic fractures in your enamel or even gum injury. Some even experience having a broken teeth because of chewing ice. This is most especially true if you have just visited your dentist and have a dental work done. If you also have a brace, chewing ice will do more harm to you than
Tooth is composed of three hard tissues enamel, dentin and cementum .The colour of the tooth is determined by reflectance of dentin and thickness of enamel[30].As cementum is in root portion of the tooth its influence on determining the color of the tooth is not much. Tooth color is different among the different people, different teeth in same person and different areas of the same tooth[31].Tooth color is not constant and it changes due to various reasons.According to the location of the stain the
INTRODUCTION During restoration of an affected tooth, if any margins between the composite restoration and tooth of concern are open, micro-leakage can occur1. Micro-leakage is a phenomenon in dentistry resulting from imperfect bonding that allows the movement of bacteria and fluids between the restoration and tooth of interest2. When a composite restoration is placed and undergoes polymerization through curing, shrinkage occurs. Research has shown that the percent of gaps between composite restorations
abrasives to brush off any unwanted particles and light stains. Examples of abrasives include calcium carbonate, dehydrated silica gels, hydrated aluminum oxides, magnesium carbonate, phosphate salts and silicates. Fluoride to strengthen tooth enamel and remineralize enamel in the early stages of tooth decay. Humectants to prevent water loss in the toothpaste. Examples include glycerol, propylene, glycol and sorbitol. Flavoring agents, such as saccharin and other sweeteners improve taste Thickening agents
these views regard fluoridation of water to be a sort of mass medication and find it to be an immoral activity. On top of that, many support their views with unreliable evidence that links the practice of fluoridation to mouth difficulties such as enamel fluorosis and other illnesses. Water fluoridation should continue to be the leading method in the distribuition of fluoride to the general population because of its positive effects on the human body. Beginning in the mid 20th century, many exploratory
Root Surface Caries Caries can affect any surface of the teeth. The most commonly seen caries are found on the crown of a tooth, above the cemento-enamel junction, it is also possible for caries to form on the root surface, below the cemento-enamel junction. Dental root caries has received a great deal of attention in the past few decades. A variety of different patients are at risk for root surface caries. Dentists use several methods of treatment. Root surface caries are also called cemental caries
INTRODUCTION Resin composite restorations are becoming have had a significant increase in popularity over the last few decades, and have become the patient’s preferred choice in filling material, due mainly due to their enhanced esthetics when compared to other restorations, as well as their ever-increasing durability. These factors have led to a large increase in demand from patients.1 As patient demand for this restorative material increases, so too do patient expectations for comfort and longevity
