Gutta Percha Points in Canada vs the US: Which Class Applies?

Quick facts

• Gutta percha is made from the coagulated sap of certain tropical trees and is used to fill the root canal of a tooth; it is softened by heat, inserted into the canal, and hardens as it cools.
• United States: 21 CFR 872.3850 places gutta percha in Class I with general controls, and exempts it from premarket notification subject to the limitations in 21 CFR 872.9.
• Other endodontic materials in the same part of the code sit in other classes: a root canal filling resin is Class II where chloroform is not an ingredient and Class III where it is, and a root canal post is Class I and exempt.
• Canada: there is no named entry. Gutta percha is inserted into the root canal, which means it enters the body through an artificially created opening, and Rule 1(1) of Schedule 1 to the Medical Devices Regulations, SOR/98-282 classifies a surgically invasive device as Class II.
• The result is a one-class gap on a small, inexpensive item: Class I in the United States, Class II in Canada.
• Canadian regulation text used here is current to 2026-09-21 and last amended 2026-06-17, as stated on the official consolidation.

Gutta percha is the material that fills most root canals, and it is a good example of how a low-cost consumable can still carry a class that differs between two neighbouring markets. The American code names the material and puts it in Class I with a premarket exemption. Canada classifies by what the material does: because it is placed inside the root canal, it is a surgically invasive device and lands in Class II. This article sets out both routes, the endodontic materials that sit alongside it, and the record an endodontic practice should hold.

What is gutta percha in each classification system?

The American identification paragraph is short and unusually concrete. Section 872.3850(a) describes gutta percha as a device made from coagulated sap of certain tropical trees intended to fill the root canal of a tooth, and states that the gutta percha is softened by heat and inserted into the root canal, where it hardens as it cools.

That wording fixes three things: the material, the destination and the method. It is the destination that matters most for the Canadian comparison, because the destination is what brings the Canadian rule into play.

The classification paragraph places the device in Class I with general controls and exempts it from premarket notification subject to the limitations in section 872.9.

Canada writes no paragraph for the material. Two definitions and one rule decide the outcome:

• Invasive device — a device intended to come into contact with the surface of the eye or to penetrate the body, either through a body orifice or through the body surface.
• Surgically invasive device — an invasive device intended to enter the body through an artificially created opening that provides access to body structures and fluids.
• Rule 1(1) — all surgically invasive devices are classified as Class II.

An endodontic access preparation creates the opening, and the point is placed through it into the canal. The material therefore meets the definition of a surgically invasive device, and Rule 1(1) reaches it.

How does the gutta percha class differ between Canada and the United States?

This is a clean one-class divergence, and it does not depend on how the material is used in the operatory.

Item	Canada	United States
Named entry	None in Schedule 1	21 CFR 872.3850
Class	Class II as a surgically invasive device	Class I with general controls
Basis for the class	The material enters the body through an artificially created opening	The material is named as a generic type and placed in a class
Premarket notification	No named entry to exempt	Exempt subject to the limitations in 872.9
Neighbouring root canal post	Rule 3(b), Class I as an instrument or Rule 1(1), Class II if it enters the canal	872.3810, Class I, exempt
Special controls concept	Not a Canadian mechanism	Not applied to this generic type

The American decision was made by generic type and by material. Gutta percha is a naturally derived, long-established, low-risk filling material, and the code says so in one word.

The Canadian decision is made by placement. Rule 1(1) does not look at whether the material is soft, cheap or long-established; it looks at whether the device is surgically invasive. Because gutta percha fills the root canal, it is.

That is why the same point that leaves a factory as a Class I exempt device in one market is a Class II device in the other, and why the gap does not narrow if the point is sold in a different size or a different taper.

Which endodontic materials sit near gutta percha in each code?

The materials that complete the same root canal treatment carry different classes, and the differences are instructive.

Device	Canada	United States
Gutta percha point	Rule 1(1), Class II	872.3850, Class I, exempt
Root canal filling resin without chloroform	Rule 1(1), Class II	872.3820(b)(1), Class II
Root canal filling resin containing chloroform	Rule 1(1), Class II	872.3820(b)(2), Class III, with a premarket approval date
Root canal post	Class I or Class II depending on placement	872.3810, Class I, exempt
Endodontic file, reamer and spreader	Rule 3(b), Class I as dental instruments	872.4565, Class I, exempt
Root canal sealer	Rule 1(1), Class II	Section by material

Two features stand out. The first is the American resin section, which changes class on a single ingredient. Section 872.3820 places a root canal filling resin in Class II if chloroform is not used as an ingredient, and in Class III if chloroform is used, and it adds a premarket approval or product development protocol date of December 26, 1996 for the Class III form.

Canada does not draw that distinction. The same rule applies to both resins, because both are surgically invasive devices and Rule 1(1) does not look at the formulation.

The second feature is the treatment of the instruments. Files, reamers and spreaders are Class I on both sides, in the United States as named items in the dental hand instrument section and in Canada under Rule 3(b).

Do Canada and the United States classify an endodontic material the same way?

They agree on the instruments and diverge on the filling materials, and the divergence has a consistent cause.

The American code names materials, so it can place gutta percha in Class I and a chloroform-containing resin in Class III within the same part, using the material and the formulation as the criterion. The exemption also travels with the named generic type: gutta percha is exempt subject to section 872.9, and the Class III resin is not exempt at all.

The Canadian schedule names neither material, so both are classified by the same general rule. The rule is about placement, and both materials are placed into the root canal. The result is one class for a shelf of materials that the American code spreads across three.

For a practice that stocks several obturation materials, the practical consequence is that the Canadian class of the whole shelf is uniform, while the American class depends on which material is picked up.

A buyer or quality lead who wants to check a specific product can look up the American entry in the openFDA device classification API or the FDA classification database. On the Canadian side the class follows from the rule, and the rule text is the reference to keep.

What should an endodontic practice keep on file?

Six items, and the first three are set by the practice's own protocol.

• The material file for each obturation line. The maker's intended use statement and the lot or batch record belong with the material.
• The instrument file for files, reamers and spreaders. Cleaning and sterilization records for the instruments belong with the reprocessing log.
• The obturation record. The material, the technique and the operator belong with the patient record for the appointment.
• The device file for any powered obturation unit. Where a heat carrier or a downpack unit is used, its instructions and servicing record belong with the device.
• The maker's material composition statement. In the United States the presence of chloroform changes the class of a resin, so the composition statement is part of the regulatory file.
• The licence or clearance position. In Canada, the class and licence status; in the United States, the position of each material under its own section.

Which consumables does an endodontic operatory restock alongside its materials?

An endodontic operatory restocks isolation, suction and barrier supplies on the same cycle as its materials. For practices buying at case level, the wholesale ordering page sets out account and case terms, and the B2B wholesale collection lists the lines held for institutional buyers. The low dead space syringes cover irrigation and medication delivery, the saliva ejectors keep the field dry during obturation, and practices that want to see the monitoring and consumable lines together can start with the sterilization monitoring collection or the biological indicator 5-pack trial.

Frequently Asked Questions

What class is gutta percha in the United States?

Class I with general controls under 21 CFR 872.3850. The section exempts the device from premarket notification subject to the limitations in 21 CFR 872.9.

What class is gutta percha in Canada?

Class II, derived from Rule 1(1) of Schedule 1 to the Medical Devices Regulations. The rule classifies all surgically invasive devices as Class II, and gutta percha is inserted into the root canal through an opening created by the access preparation.

Why is a root canal filling resin a different class in the United States?

Because of one ingredient. Under 21 CFR 872.3820 a root canal filling resin is Class II if chloroform is not used as an ingredient, and Class III if chloroform is used. The Class III form also carries a premarket approval or product development protocol date of December 26, 1996.

Does Canada draw the same chloroform distinction?

No. Rule 1(1) applies to a surgically invasive device without regard to the formulation, so a root canal filling resin without chloroform and one containing chloroform are both classified by that rule.

What class is a root canal post?

Class I and exempt in the United States under 21 CFR 872.3810, which describes a post made of austenitic alloys or alloys containing 75 percent or greater gold and metals of the platinum group. In Canada the answer depends on placement, because an item cemented into the canal is a surgically invasive device.

Are endodontic files and spreaders classified as materials?

No. They are instruments. In the United States they are named items in the dental hand instrument section, 21 CFR 872.4565, and are Class I. In Canada they fall under Rule 3(b), which classifies all surgical or dental instruments as Class I.
