Full title and description

ISO 9917-1:2007 — Dentistry — Water‑based cements — Part 1: Powder/liquid acid‑base cements. This international standard specifies requirements and test methods for powder/liquid acid‑base dental cements intended for permanent cementation, lining and restoration (hand‑mixed and encapsulated forms).

Abstract

ISO 9917-1:2007 defines performance criteria, classification (luting agent, base/liner, restorative), and laboratory test methods for powder/liquid acid‑base dental cements, and explicitly excludes resin‑modified water‑based cements. The standard includes normative annexes covering specific test methods such as compressive strength, acid erosion, optical properties, acid‑soluble arsenic and lead, and radiopacity.

Scope

Specifies requirements and test methods for powder/liquid acid‑base dental cements used for permanent cementation, lining and restoration; applicable to both hand‑mixed and encapsulated cements. The standard sets limits for material properties according to intended use (luting, base/liner, restorative) and does not cover resin‑modified water‑based cements.

Key topics and requirements

• Definition and classification of powder/liquid acid‑base dental cements (luting agents; bases/liners; restorative materials).
• Minimum performance criteria and acceptance limits for properties by use category (e.g., working/setting time, compressive strength, solubility, film thickness, dimensional stability, radiopacity).
• Standardized test methods and normative annexes, including: determination of compressive strength; determination of acid erosion; determination of optical properties (for restorative glass‑polyalkenoate cements); determination of acid‑soluble arsenic and lead; and determination of radiopacity.
• Exclusion: resin‑modified water‑based cements are out of scope (these are covered in the related Part 2).
• Requirements intended to support product specification, production quality control and comparative laboratory evaluation.

Typical use and users

Used by dental materials manufacturers (product development and specification), independent and in‑house testing laboratories (quality control and conformity testing), regulatory and notified bodies reviewing dental materials, and researchers evaluating material performance. The standard informs lab test protocols and acceptance criteria for powder/liquid acid‑base cements.

FAQ

Q: What is this standard?

A: ISO 9917‑1:2007 is the International Standard titled "Dentistry — Water‑based cements — Part 1: Powder/liquid acid‑base cements," specifying requirements and test methods for powder/liquid acid‑base dental cements used for permanent cementation, lining and restoration.

Q: What does it cover?

A: It covers classification, performance limits and laboratory test methods for powder/liquid acid‑base cements (hand‑mixed or encapsulated), including tests for compressive strength, acid erosion, optical properties (where applicable), acid‑soluble toxic elements and radiopacity; it excludes resin‑modified water‑based cements.

Q: Who typically uses it?

A: Manufacturers, quality control and testing laboratories, dental materials researchers, and regulatory bodies use the standard for specifying, testing and assessing powder/liquid acid‑base dental cements.

Q: Is it current or superseded?

A: ISO 9917‑1:2007 is withdrawn/superseded; a newer edition, ISO 9917‑1:2025, has been published and replaces the 2007 edition. Users should refer to the latest edition for current requirements.

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 9917 series (water‑based dental cements). Part 2 addresses resin‑modified water‑based cements (ISO 9917‑2).

Q: What are the key keywords?

A: Dental cement, acid‑base cement, powder/liquid, glass polyalkenoate, luting cement, restorative cement, film thickness, compressive strength, radiopacity, ISO 9917.
