For Dental Clinic in South Delhi
Let’s learn about Dental fillings.
Dental caries (tooth decay) has historically been considered the most important component of the global oral disease burden. Dental caries is still a major public health problem in most high income countries. Dental caries levels, prevalence rates and dental caries experience has tended to increase rapidly with changing lifestyles and growing consumption of sugars, inadequate exposures to fluorides; etc.
Dental materials are used for direct restoration (filling) of a tooth in order to save its function while
Indirect materials include pre-formed metal crowns, dental porcelain, and cast restorations. Types of direct restorative materials are
- Dental amalgam (silver-tin-copper amalgams containing mercury),
- Resin-based composite materials (RBC),
- compomers and giomers (glass filler modified composites),
- glass-ionomer cements, light cured resin modified materials and
- Ceramics- Inlays/Onlays
What’s best for me?
Depends on how big is the cavity, what is load taking capacity of that tooth, your socio-economic standards, and any special needs due to presence of any disease etc.
While tooth-colored restorative materials are generally more expensive than amalgam, they offer an aesthetic alternative to traditional amalgam fillings. However there are concerns about their longevity and wear particularly in areas subjected to masticatory forces. Microleakage is also a disadvantage but it can be reduced with proper manipulation and strict clinical procedures.
DIRECT FILLINGS- No Lab Backup
Resin-based composite restorative materials are complex blends of polymerizable resins mixed with glass powder fillers. To bond the glass filler particles to the plastic resin matrix, the filler particles are coated with silane, an adhesive coupling molecule. Other additives also are included in composite formulations to enhance radiographic opacity for better diagnostic identification, to facilitate curing and to adjust viscosity for better handling. Color and translucency of dental composites are modified to mimic the color and translucency of teeth, making them the most esthetic direct filling material available.
Glass ionomers are tooth colored filling materials that can be used to restore cavities with low load-bearing requirements. They have fluoride releasing capacity which prevents secondary caries.
Resin modified glass ionomers are similar to conventional glass ionomers but have better properties and handling characteristics. Acrylic resins similar to those used in resin-based composites are added to the material to reduce sensitivity to the setting environment and to provide the ability for the material to be rapidly cured. They have better mimicking ability of the enamel translucency.
White But Indirect- Materials of Choice
INDIRECT- Lab support required.
Typically, tables have lines between the rows and columns. However, some tables in this template are formatted with hidden lines. To reveal the underlying rows and columns of a table, click Show Gridlines on the Table menu. This feature is especially helpful when you’re not sure if your document has tables in it or not.
You can change the colors of rows and columns by clicking the area you want to change, clicking Borders and Shading on the Format menu, clicking the Shading tab, and then picking a color. At this point, you should specify whether you want the shading to apply to just the text, the selected paragraph(s), the whole cell, or the entire table.
The dark blue rule that appears over a headline is a characteristic of the headline’s paragraph: It’s formatted to have a dark blue rule above it. This and all the other characteristics of this paragraph are identified as a paragraph style named Heading 2. The first headline in this newsletter does not have a rule since it appears at the beginning of the newsletter. It’s a style called Heading 1.
