This document specifies test methods for the evaluation of biological effects of medical devices used in dentistry. It includes testing of pharmacological agents that are an integral part of the device under test. This document does not cover testing of materials and devices that do not come into direct or indirect contact with the patient's body.

Overview

EN ISO 7405:2025 - Dentistry: Evaluation of biocompatibility of medical devices used in dentistry (ISO 7405:2025) is the latest CEN-adopted edition for biological evaluation of dental medical devices. Approved by CEN in June 2025 and published as a European standard, it specifies test methods and procedures to assess biological effects of dental devices - including devices that contain pharmacological agents integral to the device. The standard explicitly excludes materials and devices that do not come into direct or indirect contact with the patient.

Key topics and requirements

Device categorization: Guidance on categorizing devices by nature of contact (non-contact, surface-contacting, external communicating, implantable) and by duration of contact (limited, prolonged, long-term).

Biological evaluation process: Framework for selecting appropriate tests, overall assessment, and re-evaluation when design, materials or manufacturing change.

Test groups and methods:

Physical and chemical characterization: Baseline data to inform biological testing.
Group I / II / III tests: Structured classification to determine in vitro and in vivo testing needs.
Specific dental test procedures: Detailed methods for dental-relevant assays such as agar diffusion test, filter diffusion test, pulp and dentine usage test, pulp capping test, and endodontic usage test.

Sample preparation: Recommendations for preparing test specimens, including light-curing and chemically setting materials, and use of positive control materials.

Reporting and assessment: Requirements for documenting methods, controls, assessment parameters and test reports to support regulatory or conformity claims.

Practical applications and users

EN ISO 7405:2025 is intended for:

Dental device manufacturers - to plan preclinical biocompatibility testing and support regulatory submissions.

Biomedical and materials test laboratories - to implement standardized in vitro and in vivo dental-specific assays.

Regulatory affairs and quality teams - to assess compliance and prepare technical files for market approval.

R&D and product development - to guide material selection, risk assessment and safety verification.

Notified bodies and conformity assessors - to evaluate evidence of biological safety for dental devices and integrated pharmacological agents.

Practical uses include design verification, risk management, preclinical safety testing, and re-evaluation after formulation or process changes.

Related standards

The standard aligns with broader biological evaluation frameworks used in medical device regulation. For comprehensive program design, organizations commonly reference complementary biological evaluation standards and national regulatory guidance when preparing submissions.
