Centrix.

Centrix's history page says Dr. William B. Dragan started the company in 1970 in his basement to deliver composite and cement from the pad to the tooth. The Mark I syringe and C-R tube were the first products after large composite makers declined the idea. The name Centrix is his alteration of the word centric. The company says it is now in a facility in Shelton, Connecticut. A March 2025 memorial says Dr. Dragan was born March 15, 1934, graduated from Temple University dental school in 1958, died on January 11, 2025, and that his son Bill Dragan is president and CEO. The memorial credits him as inventor or co-inventor on about 95 patents.

The delivery line grew past the steel barrel. Centrix lists an all-plastic Mark II, a Mark III, and needle tubes for small preparations. A 2021 company article says six additional syringe and gun models followed the original and that plastic snap-fit versions increased expression force. Those are company descriptions of its own redesigns.

Preventive products sit beside the syringe. FluoroDose is the varnish named in the memorial, including the 2024 DraganBerry flavor. An older history page mentions more than 140 employees worldwide. That sentence is the company's, from a page that also misstates the month of Dr. Dragan's death relative to the memorial. Use the memorial for the date, January 11, 2025, and treat the headcount as an undated company figure.

Centrix does not manufacture the patient's chair or the composite itself in the story it tells. It manufactures the path the composite takes into the tooth, plus related applicators and a varnish. The composite brand can be someone else's. The tube has to fit the viscosity.

Centrix suits a restorative practice that places composites and cements with a syringe rather than a hand instrument alone, and a hygiene practice that uses FluoroDose. The universal composite guide chooses the material. The Centrix tube is how a scooped or injected increment gets to the box. The fluoride varnish guide is the preventive comparison.

Pediatric offices are a natural varnish buyer. The flavor line, including DraganBerry, is a compliance detail, not a fluoride-dose change. Confirm the fluoride content on the unit dose.

A laboratory is rarely the customer. These are chairside tools. Office products is the right directory.

Other companies now sell unit-dose tips that resemble the C-R idea. Centrix's claim is that the 1970 syringe was the first practical one. Newer guns from Centrix and from composite manufacturers compete on force and tip size. Match the tip to the composite you already adopted. A tip that fits one brand's capsule may not fit another's.

FluoroDose competes with other varnishes in the fluoride guide, including products from Premier and Young Dental. Compare unit dose, flavor, and whether the varnish contains the fluoride form your protocol names.

The Benda Brush competes with other disposable applicators. It does not etch, bond, or cure. Those are still separate steps.

Standardize the gun and the tube together. A Mark I steel syringe and a later plastic gun do not share every tube. Ask which tubes are current before you buy a year's supply of plugs that fit a discontinued barrel.

The Shelton facility is the company address in the history narrative. Street-level ship-to detail should come from the current contact page or your dealer. Leadership is Bill Dragan, per the 2025 memorial. Warranty on a reusable gun versus a disposable tube will differ. Get both.

Training is the technique the founder described: load the tube, inject from the bottom of the preparation, avoid voids. That is not a formal certification. New assistants still need someone to watch the first restorations.
