Short answer
A cement spatula is a hand-held dental tool used to mix dental cement powder and liquid on a pad or slab. U.S. regulation treats it as a dental hand instrument, not as part of the cement, and the tool a product calls for is set by that cement’s own instructions for use (IFU), not by a general rule.
Definition and scope
The FDA defines a dental hand instrument as “a hand-held device intended to perform various tasks in general dentistry and oral surgery procedures” (21 CFR 872.4565). The regulation is Class I (general controls). Its list of instruments does not name a cement spatula, and the FDA product classification database has no product code with that name (openFDA classification API). Related codes under the same regulation include “Instrument, Filling, Plastic, Dental” and “Instruments, Dental Hand”.
The cement is a separate device. Under 21 CFR 872.3275, zinc oxide-eugenol cement is Class I, while dental cement other than zinc oxide-eugenol is Class II. The regulation describes dental cement as intended to serve as a temporary tooth filling or base cement, to affix devices such as crowns or bridges, or to protect the tooth pulp.
How it is used in practice
The use of the spatula is defined by the cement maker. As one example, the IFU for AT&M Biomaterials’ glass ionomer luting cement (document dated 2026-05-27) states that the cement is mixed “using a plastic cement spatula”. The kit lists powder, liquid, a plastic spoon and a mixing pad. These statements apply to that product only.
Related concepts
- Mixing pad or slab: the surface the spatula works on; in the IFU above it is supplied in the kit.
- Dappen dish: a small container used for dental liquids; see dappen dish.
- The cement itself: for the chemistry and classification of one cement family, see glass ionomer cement.
- Restorative materials: composites are handled differently from cements; see dental composite resin.
- Other hand instruments: for another class of precision hand tools and how they are described, see microsurgery instruments.
Where it matters for labs, clinics and supply decisions
Because no regulation or product code defines a “cement spatula” on its own, the cement’s IFU is the document that tells staff what the tool must be. The table below shows which tool and surface that one IFU specifies, so a supply list can be checked against the IFU rather than against a catalogue heading.
| Item | What the AT&M IFU states for its product |
|---|---|
| Mixing tool | Plastic cement spatula |
| Mixing surface | Mixing pad supplied in the kit |
| Ambient conditions | The IFU states a room-temperature range for mixing; see the document |
Another cement will state different values. Read the IFU of the specific product each time.
Common misunderstandings
- “The FDA lists cement spatulas.” The dental hand instrument regulation does not name one, and the classification database has no product code under that name.
- “One spatula suits every cement.” The example IFU specifies a plastic spatula for its product; that statement is not a rule for other cements.
- “The spatula and cement share a classification.” The instrument falls under 21 CFR 872.4565; the cement under 21 CFR 872.3275.
FAQ
What is a cement spatula used for?
It is used to mix dental cement powder and liquid into a smooth paste. In the cited IFU the mixing tool is a plastic cement spatula.
Is a cement spatula a regulated medical device?
Dental hand instruments are Class I devices under 21 CFR 872.4565, subject to general controls. The regulation does not name a cement spatula specifically.
Who decides which spatula to use?
For a given cement, the manufacturer’s IFU states the mixing tool, surface and conditions.
