Frequently Asked Questions About Resiment® and Resiment Ready-Mix®

 

Can Resiment Chemical Cure be used on dentin?

Yes, Resiment may be used safely and effectively used on dentin, enamel, composite, or metal.

Is a dentin bonding agent necessary?

Yes. The reason for a dentin bonding agent is two-fold; stronger adhesion and to prevent any possibility for sensitivity.

What is a dentin bonding agent and how does it work?

A dentin bonding agent is a linking or coupling agent between the dentin and the Resiment®. Prior to placing the adhesive, the dentin surface is etched or conditioned. This changes a small layer of the dentin to become more receptive to the adhesive. A dentin bonding agent also reduces sensitivity by occluding the dentinal tubules which can number over a million when a tooth is prepared for a crown.

Which dentin bonding agents should I use?

Any system that has full or conditional acceptance by the ADA or has documented research published in referred dental journals.

Should I acid etch the tooth before applying a dentin bonding agent?

Most authorities say yes; The reason for this is that the mild phosphoric acid will clean the smear layer.  (Smear layer is the debris or material that forms on the tooth structure and reacts like a separating medium and will not allow cement to adhere).

Does Resiment require exact mixtures of catalyst and base?

No.  Tests conducted at Loma Linda University, CA revealed that either component could be off by 1/3 and not diminish the strength. This is one reason why the product is so user friendly. Powder and liquid cements have to be exact or the final results are questionable.

Can Resiment be used with noble metals like gold?

Yes, but first they should be micro-etched and then tin plated. Another method would be to use a metal primer on the gold after roughening.

When should I start cleaning Resiment from a newly cemented crown or prosthesis?

Test the cement with a sharp tipped instrument; Start cleaning when the cement has the initial set or becomes rubbery (about ½ minute after seating). If you wait until final cure Resiment is extremely difficult to remove.

Will acid etch hurt pulp?

Several studies have shown that a short etch of 15 seconds using phosphoric acid 37% will remove the smear layer without adversely affecting the pulp.

Should Maryland Bridge lateral wings and other metal restorations to dentin be sandblasted before cementation?

Yes, and a metal primer should be applied.

Should enamel be etched before cementation of Maryland Bridges?

Yes, because the surface of the enamel must be prepared to bond to the unfilled resin.

Is Resiment good for implant abutments?

Yes, in fact Resiment is the cement of choice by many implant clinicians and is recommended by many implant companies to insure the doctor uses the correct cement.

Is the strength of standard Resiment different from fluoridated Resiment?

Test results at Ohio State University and Loma Linda Dental Schools have indicated that the fluoridated Resiment maintains the same high strength and in some situations is even stronger.

If the implant abutment is sub gingival and oozing does occur, will the strength be diminished if cement is contaminated?

Again, test results at Loma Linda revealed that Resiment maintained more strength in this situation than other cements tested.
