Technical Details

The Making of the Metal Dento-Infusor Tip

Dr. Fischer designed the earliest version of the Metal Dento-Infusor tip in the basement of his home in Utah. In one of his lab experiments, Dr. Fischer pulled an IV syringe from his supply cabinet, cut off the needle point, and used an orthodontic tie wire to pull a retraction cord through the needle. Using orthodontic pliers, he then bent the needle into the shape the MDI tip still comes in today.

Designed for Profound Hemostasis

The Metal Dento-Infusor tip is specially designed with a blunt, bent cannula and a padded brush end. The tip’s first-of-its-kind design is ideal for delivering hemostatic right where it’s needed in the capillary openings.

Still the Best

The Metal Dento-Infusor tip was the first tip in what is now a complete line of specially designed delivery tips. Even after all these years, the Metal Dento-Infusor tip remains paramount for profound hemostasis.

Comfort Hub Feature

The Comfort Hub feature provides larger, ergonomically designed wings for an improved user experience while attaching or removing the Metal Dento-Infusor tip. Clinicians can apply greater torque to ensure secure attachment or easy removal with less finger stress and discomfort.


Placing Hemostatic Agent


The Metal Dento-Infusor tip infuses hemostatic agents into capillaries, forming a cork-like “plug,” then wipes coagulum away.


Subgingival preparation results in a bleeding sulcus. The Metal Dento-Infusor tip rubs hemostatic agents firmly against bleeding tissues to immediately arrest bleeding and to provide profound hemostasis.


Tissue Management Technique Step by Step

See Instructions for Use for complete instructions, warnings, and precautions.

Step 1

With the Dento-Infusor™ tip, scrub hemostatic firmly against cut bleeding tissues until bleeding stops.

Step 2

Give firm air/water spray to remove residual coagulum and to test for profound hemostasis. If bleeding continues, repeat.

Step 3

After complete hemostasis has been attained, excellent retraction is achieved using Ultrapak™ knitted cord placed with the Ultrapak™ packer

Frequently Asked Questions

  • Applying pressure to the sulcus and scrubbing and rubbing seems counterintuitive to me. Wouldn’t that technique cause even more bleeding?

    We admit that it does seem counterintuitive at first. But years of quality hemostasis achieved with this technique has taught us that it truly does work. Scrubbing and rubbing the hemostatic into the cut tissue infuses the solution into the capillary openings, and the brush end of the Metal Dento-Infusor tip removes the excess off the cut tissue so that the only place where coagulum remains is within the cut capillary opening. A diamond bur rotating at a half million RPMs will cut connective tissue and epithelium, but the soft padded-brush end of the Metal Dento-Infusor tip will not. In addition, coagulum may accumulate around the tip, but by rubbing and scrubbing, the solution moves down within each cut capillary opening, plugging and sealing it off. Within 1 or 2 minutes, you will notice no new coagulum forming. You know the capillaries are sealed, and you know the bleeding is stopped. Should it take longer than 1 to 2 minutes, we suggest using a stronger hemostatic like Astringedent X hemostatic agent.
  • I’ve seen other tips like the Metal Dento-Infusor tip for sale from other companies. Why should I stick with the original?

    It’s true that other companies have created tips based on the advanced design of the Metal Dento-Infusor tip. But these tips are not manufactured with the same quality as the original Metal Dento-Infusor tip. When you purchase tips of a lower quality, you will likely find many defective tips in the pack, which can be frustrating—not to mention expensive. The more tips you end up throwing away, the more money you end up wasting. Take it from others who have learned the hard way: don’t settle for knockoffs!
  • Where is the Metal Dento-Infusor tip manufactured?

    The Metal Dento-Infusor tip is proudly manufactured in the USA.
  • What is the Comfort Hub design and why has it been added to the Metal Dento-Infusor tip?

    The Comfort Hub design is an exclusive Ultradent tip design that includes larger wings for easy syringe attachment and removal. The increased surface area allows for a secure grasp of the tip while offering a slightly concave, ergonomic hub that dramatically improves ease of use. While attaching or removing the tip, greater torque can be applied with less finger stress and discomfort.
