Which cement is better OPC cement or PPC cement?
Uses of Portland Pozzolana Cement (PPC):
- This Cement is Flyash based cement recommended for brick masonry, plastering, tiling, and waterproofing work.
- In these works, strength isn’t the major criterion.
- PPC has an edge on OPC as PPC has a slower rate of the heat of hydration.
- Thereby PPC is prone to educe shrinkage & less cracks ), better workability, and finishing.

- Adiseal is waterproof so it is also suitable for use outside. ...
What is luting glass ionomer cement?
A glass ionomer cement (GIC) is a dental restorative material used in dentistry as a filling material and luting cement, including for orthodontic bracket attachment. Glass-ionomer cements are based on the reaction of silicate glass-powder (calciumaluminofluorosilicate glass) and polyacrylic acid, an ionomer.
What are the requirements for luting cement?
Luting agent requirements Basic mechanical, biological, and handling requirements must be met by the cement : It must not harm the tooth or tissues. It must allow sufficient working time to place the restoration. It must be fluid enough to allow complete seating of the restoration.
Which cement is used for teeth?
Dental cements Zinc phosphate, zinc oxide eugenol, and polycarboxylate cements are available and still used in dentistry. However, glass ionomer and resin composite cements are primarily used today because of their superior properties and handling characteristics.
Which is the best luting cement?
Glass Ionomer Luting Cement These cements have many positive characteristics that make them relatively desirable in the dental marketplace. One of the greatest advantages is fluoride release. Glass ionomer cements also possess good adhesion to both enamel and dentin and form relatively strong bonds.
Can luting cement be used for restoration?
It is mainly provisional crowns and bridges (fixed partial dentures) that are cemented with eugenol-containing temporary cements, but sometimes they may be used for permanent restorations.
What cement Do dentist use for crowns?
Zinc Phosphate: Known as the original cement, zinc phosphate is used for preparing crowns, inlays, onlays, orthodontic appliances, and partial dentures. This cement composition produces high compressive strength, an acceptable film thickness, and high tensile strength that makes it hard to beat.
What does luting mean in dentistry?
A luting agent is a cement that your dentist uses to help secure a dental restoration — such as a crown, inlay, onlay or fixed bridge — to your teeth.
Can you use dental cement on a broken tooth?
Use a cold pack on your cheek or lips that cover the broken tooth. The cold helps reduce swelling and alleviates pain. Look for temporary dental cement at the drug store. Use it to cover the part of the tooth that remains in your mouth until you see a dentist.
What do dentists use to glue teeth?
Dental cement is the glue that bonds a wide range of dental and orthodontic applications to the tooth surface. Because of this wide range of use, dental cement comes in a variety of forms that are used for temporary or permanent restorations. Dental cement is chemical compounds that bond two surfaces.
What is the strongest cement for crowns?
Several laboratory studies have determined that bonding crowns with resin cements increases the retention strength of the crown more than cementing with glass ionomer or zinc phosphate cements.
Which dental cement is strongest?
PANAVIA™ V5 is the strongest dentin bonding cement we have ever developed.
What is luting agent?
A luting agent is a cement that your dentist uses to help secure a dental restoration — such as a crown, inlay, onlay or fixed bridge — to your teeth. According to a review in the American Journal of Materials Science and Engineering (AJMSE), dental cements have been used for many years and possess unique chemical properties ...
What properties of cement are needed for restoration?
Anticavity properties: The cement should help to prevent the formation of decay in the area around the restoration. Low viscosity and film thickness: An ideal cement should be very thin when applied so as not to alter the fit of the restoration.
What is dental cement made of?
Most consist of a powder and liquid that create a chemical reaction when mixed together, causing the cement to set. When choosing a dental cement, your dental professional will factor the composition of the restoration it will be used with and the specific requirements that your situation calls for. According to the AJMSE review, some of the more ...
What is polycarboxylate cement?
Polycarboxylate: This can be used as a final or intermediate cement. Polycarboxylate cement has also been used for orthodontic purposes and insulating bases. Glass ionomer: Developed in the late 1960s, glass ionomer cement consists of a silicate glass powder and a liquid solution of polyacrylic acid.
Does cement protect teeth?
Heat insulation: The cement should protect the tooth from sensitivity to hot and cold foods and beverages . Adequate bond strength: The agent should be able to bond to hard tooth surfaces. Long shelf life: A dental professional should be able to store the cement for a period of time without it losing effectiveness.
Does cement affect tooth color?
Sufficient light transparency: In the case of tooth-colored restorations, the cement should not affect the color or aesthetic of the final restoration. Resistance: The act of chewing should not dislodge a restoration once it is cemented. Heat insulation: The cement should protect the tooth from sensitivity to hot and cold foods and beverages.
Does dental cement dissolve in saliva?
According to an article in the Journal of Advanced Medical and Dental Sciences Research, these properties include: Low resolution ratios within liquids in the mouth: This means that the cement should not dissolve or "wash out" in the presence of saliva or other liquids typically found in the mouth. Biocompatibility: Dental cement should not be ...
What is luting cement made of?
It is usually made up of a powder (zinc oxide and magnesium oxide) and a liquid (aqueous phosphoric acid). Mixing of zinc phosphate is done by using a spatula to gradually incorporate the powder into the liquid. By using a chilled glass slab, the working time will be increased.
What is a luting agent?
Caulk Company in the early 1900s. A luting agent is an application of a dental cement connecting the underlying tooth structure to a fixed prosthesis. To lute means to glue two different structures together. There are two major purposes of luting agents in dentistry – to secure a cast restoration in fixed prosthodontics ...
What is provisional luting agent?
Provisional (or temporary) luting agents are used specifically for inter-appointment fixation of temporary restorations, prior to cementation of a permanent restoration. It is mainly provisional crowns and bridges (fixed partial dentures) that are cemented with eugenol-containing temporary cements, but sometimes they may be used for permanent restorations.
What is RMGIC cement?
RMGIC, also known as hybrid cements, was developed with the purpose of eliminating weaknesses of the traditional glass-ionomer (GI) to enhance its existing properties . The addition of polymerisable resins ( hydrophilic methacrylate monomers) results in higher compressive and tensile strength, as well as lower solubility, all of which are ideal properties of a dental luting agent. The setting reaction takes place with the relatively quick polymerisation of resins and gradual acid-base reaction of GI. At the early stage of setting reaction, RMGIC has a certain degree of solubility at the margins. Therefore, it is important to keep the margin dry for around 10 minutes to minimise loss of marginal cement.
What is dual cured resin cement?
Dual-cured resin cements. It consists of a light-activated paste mixed with a chemical catalyst for resin polymerisation. It is widely used for luting dental restoration whereby the thickness allows penetration of light for partial curing only.
What is the first cement to bind to tooth structure?
Zinc polycarboxylate was the first cement to bind to tooth structure. It is generally made up of the same powder as zinc phosphate (zinc oxide and up to 10% magnesium oxide) but uses a different liquid – aqueous copolymer of polyacrylic acid (30-40%).
What is a dental lute?
Dental lutes can be classified in many ways, some of which based on: (i) user's knowledge and experience of use. conventional: zinc phosphate, zinc polycarboxylate, and glass-ionomer (GI) contemporary: resin-modified glass-ionomer cement (RMGIC) and resin. (ii) type of setting mechanism.
