Access Edge works great. Superior in many ways to Traxodent and Expasyl. Easier to place and won't pull away when placing. Much easier to rinse away. It doesn't dry up like Expasyl because of the unit dispensing. I am no longer ordering the other two products.

- Dr. Cuevas (Fairfield, CT)

The unit dose fluoride is a real time-saver and easy to apply.

- Dr. Michael Kaner (Trevose, PA)

Clean up and application is much easier using Centrix brushes and applicators.

- Dr. Louis Kaufman (Chicago, IL)

I like Centrix for their innovative products and their desire to make dental practice easier for both the doctor and the patient.

- Dr. Howard Glazer (Fort Lee, NJ)

GingiTrac has simplified my crown and bridge procedures therefore reduced my stress levels.

- Dr. David Hecht (Forked River, NJ)

I will say SuperCure is the best core buildup material out there!

- Dr. Michael Smulewitz (Scotch Plains, NJ)

- Dr. Felicia Chu (Elgin, IL)

Access Crown allows me to make temporary crowns in half the time.  No need to polish and the margins are perfectly clear.

- Dr. Randy Pritz (New York, NY)

Tempit is very easy to use and hardens faster and more reliably then Cavit. Like the fast set and one time application of Encore Minimix.

- Dr. Ronald Linden (Shelton, CT)

Access Crown is the best temporary material I have ever used. Curing time and minimal shrinkage are biggest advantages.

- Dr. Ruben Romero (San Diego, CA)

I like Centrix for their innovative products and their desire to make dental practice easier for both the doctor and the patient.

- Dr. Howard Glazer (Fort Lee, NJ)

Tempit is a huge time-saver. Less than thirty seconds to fill after an endo, It honestly takes longer to place the cotton pellet.

- Dr. Jonathan Conover (Cincinnati, OH)

I love using SuperCure!  It's ease of dispensing, bulk curing, and NO WAIT to continue on with my preps are awesome.

- Dr. David Wright (Fresno, CA)

Tempit has a nice working consistency. Doesn't crumble on you like when Cavit gets older.

- Dr. Felicia Chu (Elgin, IL)

Tempit is a time saving, fast setting, easily applied material used to seal endodontically-treated teeth in between visits. The unit dose delivery system is ideal in preventing cross-contamination. There is no mixing, no mess, no fuss. It increases our efficiency by spending less time on mixing, applying and on cleanup. My assistant can't decide which part she likes better, the fact that there's no mixing or no mess.

- Dr. Michael Kaner (Trevose, PA)

The Centrix disposable tubes and plugs are a much more efficient way of delivering materials, both low and high viscosity with less waste. The needle tips are perfectly designed for precise placement of materials whether it's cement in a post prep, a proximal box or a core buildup.

- Dr. Michael Kaner (Trevose, PA)

I've used a whole range of centrix products for many years. They are always finding new and better ways to deliver quality dentistry to my patients. I really appreciate that and I have a great deal of trust in what they create for dentistry.

- Dr. Thomas Ohlson (Stamford, CT)

Centrix fluoride varnish is the best, most cost-effective varnish that we have ever used in our office.  It's the perfect amount for children, teens, and even adults, plus goes on almost invisibly.

- Dr. Gregg Fink (Newark, DE)

Love the GingiTrac, much easier and more comfortable for the patients, instead of packing cord.

- Dr. Felicia Chu (Elgin, IL)

I have been very pleased with the value, time savings, and strength of the Centrix product Access Crown. My assistant is able to make perfect temporaries that don't break in about 5 minutes.

- Dr. Charles Newens (Carmichael, CA)

We used to use IRM but it was so sticky and it sometimes came out by the time our patients got to the parking lot, but then our wonderful Centrix representative told us about Tempit, and we have not stopped using it since.  It is light-cured and saves not only my own time but time for my patients too (because they do not have to come back when their IRM temporary filling comes out)!  Centrix truly makes dentistry for us at Olympia Fields Dental Associates easier...thank you!

- Dr. Roshan Parikh (Olympia Fields, IL)

No crown or bridge impression is made in my office without Centrix's GingiTrac. It's so easy to use, and gives me very accurate impressions every time.

- Dr. Chris Ricker (Palm Beach Gardens, FL)

One of the more forward thinking dental supply companies — always looking to reinvent a product to make it better and easier to use. Very responsive to dentist input.

- Dr. Larry Krevitz (Hatboro, PA)

I use Centrix almost exclusively for my temps, really like the ease of use, functional, and esthetic capabilities for a temporary material. I really like the Encore D/C core build up material. Cuts very similar to dentin and I like the delivery system with the unidose and metal tips.

- Dr. Jeffrey Goodman (Pennington, NJ)

I love the GingiTrac system; it is hands down the most efficient time saving retraction system in Dentistry! It works every time and is so much more comfortable to the patient than using retraction cord.  I couldn't practice without it.

- Dr. Craig Sater (Cocoa, FL)

Just about most of the products that I tested made my life a lot easier, especially the Centrix retraction and matrix material and the Access Crown temp material. I have found Access to be one of the best temp materials I have used in my 25 years and the most cost effective.

- Dr. Joseph Romanelli (Fairfield, CT)

Encore DC MiniMix by Centrix makes a Post and Core easier and faster.  Combined with a dual cure bonding agent I cement the post and make the build up at the same time.  It is easier and faster than using a cement for the post and another for the core.

- Dr. Ronald Chaiklin (North Arlington, NJ)

Tempit is a product that I have used for years.  The easy use in sealing endodontic access sites and the fact that it does not adversely affect bond strengths with bonding agents or cements makes this a superior product for everyday use.

- Dr. Terry Hopper (Austell, GA)

I have been using Centrix's Encore D/C MiniMix for over a year now. It is hands down the easiest, most efficient core build-up on the market. The price can't be beat on it as well. This core build-up blows away the competition: it is ridiculously easy to place, it doesn't slump, it cures fast, it stays in place, and it cuts well! What more could you ask for in a core-buildup material?

- Dr. Gary Klein (Harrisburg, PA)

I use Tempit for interim filling of root canal access openings.  The material is easy to adapt and firm enough to hold its shape until set.  Low stickiness to instruments and fast reliable placement with the CR syringe makes it our material of choice for short term provisional filling of the endo access.

- Dr. Jeff Kosoris (Waxahachie, TX)

The CR syringe is our workhorse for composite placement.  Most composites are available in prefilled tips that perfectly fit the CR.  I have found it to be durable, comfortable in the hand, precise in dispensing, and easy to reload with fresh tips.  It's the best product for dispensing composite resin I have found.

- Dr. Jeff Kosoris (Waxahachie, TX)

My Centrix Rep, Tammy Micenko, is experienced, knowledgeable, and has been very instrumental in the common sense implementation of Centrix products in my office. Centrix unit dose packaging has streamlined my practice. There is less material waste and its packaging is aseptic on its delivery at the chair. These products are less chair-side assistant dependent. Centrix products simplify the delivery of care making practice more enjoyable. Thank you Tammy.

- Dr. Tim Crowe (Chicago, IL)

We have switched from UltraSeal XT by Ultradent to Champ exclusively because of its simplicity. When placing sealants, our hygienists only have small window to place the sealants, before the child becomes uncooperative. With Champ, we are able to place the sealant into the grooves securely and efficiently. With the other product, we used to have to take a microbrush and "pat" down the sealant, Champ eliminates this step for us.
Thanks for making sealants go quicker for both our hygienists and our patients!

— Dr. Gary Klein (Klein Family Dentistry), Harrisburg, PA

The beauty of using GingiTrac is that not only does it offer an easy way to get nice gingival retraction, but it cleans the prep area as if you are taking a clean second impression.  Details of the prep are cleaner and easier to read. GingiTrac can be easily used with or without retraction cords depending of depth of preparation and tissue thickness.

— Dr. Allen Schneider (Springfield, VA)

Composite: Tooth-colored restorative material made up of resins and fillers. A resin with an organic substance of vegetable origin can be produced synthetically. In dentistry, resins are often in a semi-solid state, capable of being molded into place to fill cavities. Added to these resins are various types of fillers, inorganic materials such as quartz, borosilicate glass, strontium glass, and color pigments. The addition of fillers produces a reinforced or "filled resin," commonly called a composite resin or simply a "composite."

Compressive Strengths: This is the amount of force a material can support in a single impact before breaking. It is one of the easiest tests to perform and often cited in advertisements for dental materials. Compressive strength is such a commonly used physical property that has developed a greater respectability in the profession than its actual clinical relevance. There is no direct correlation between compressive strength and clinical performance. However, compressive strength does measure strength and gives an indication of a materials resistance to creep and plasticity.

Contact Angle: This is a measurement on how a liquid wets a solid. As the angle becomes smaller there is the increased ability of wetting the surface, which is preferred in pouring impression materials, or improves the penetration of the bonding material into micromechanical porosities of a substance.

Dentin blush: Red to pink discoloration of dentin due to pupil hemorrhages, usually a result of a trauma.

Dentin Smear Layer: In cases of tooth preparation where the enamel and underlying dentin are removed by rotary instruments, such as burs, and a layer of debris is created. This layer of debris is called a smear layer. At present, there is controversy surrounding the desirability of removing the smear layer from the dentin prior to application of the bonding agent, to allow a better bond. Some believe that as tubules are opened, the risk of bacterial infection and sensitivity is increased.

Erupt, Eruption: A new tooth coming in. The tooth is said to erupt when the tooth breaks through the surface of gums so you can see the tooth in your mouth.

Etching: Process by which the tooth structure (usually enamel) or porcelain is exposed to a mild acid which dissolves the surface creating an irregular, rough surface of many small pores. This irregular surface allows a physical bond between tooth and composite. The composite fills the pores and forms minute tags of the resin as the composite is solidified during polymerization. (The same process applies to etching porcelain)

Hydrofluoric Acid: The type of acid used to etch porcelain.

Hydrophilic: Having an affinity for water. The contact angle of water to a surface is used to measure wetability; lower angles are more hydrophilic. For impression materials the lower the contact angle makes them more easily poured in gypsum die stone. This is considered to be an advantage of an impression material.

Hydrophobic: Having an aversion to water. The contact angle of water to a surface is used to measure wetability; higher angles are more Hydrophobic. For impression materials the higher the contact angle makes them more difficult to pour them in gypsum die stone. This is considered being a disadvantage with impression materials.

Viscosity: Resistance of composite material to flow. If it is too thin, it will not stay in place; it will float or slide. If it is too thick, the force needed to seat the veneer may break it.

Water Sorption: Measure of the ability of a composite to absorb water. Water sorption can cause the material to weaken or discolor over time.

Wisdom Tooth: A 3rd molar. This is the eighth tooth from the center of the mouth to the back of the mouth. Wisdom teeth are often impacted (obstructed from erupting) and have to be extracted.

Working Time: The amount of time a dentist has to work with a material (composite) before it begins to set, or cure.
