Full title and description

St ISO 9873-2019 — Dentistry — Intra-oral mirrors. This international standard specifies requirements and test methods for reusable intra-oral mirrors with a coated glass reflecting surface, including requirements for metallic casings and metallic handles used in dental practice.

Abstract

ISO 9873:2019 defines performance, construction and testing criteria for intra-oral dental mirrors to ensure adequate optical quality, mechanical strength and safe use in the oral cavity. It covers materials, surface coating, dimensional and mechanical requirements, and standardized test methods for evaluating mirror performance and durability.

Scope

Specifies requirements and test methods for reusable intra-oral mirrors with a coated glass reflecting surface intended for dental use in the oral cavity. The standard also gives specific requirements for metallic casings and metallic handles and includes methods to assess optical quality, mechanical integrity and surface condition after intended cleaning/sterilization procedures.

Key topics and requirements

• Optical performance: reflectivity, absence of distortion, and detail reproduction.
• Coating and surface finish: coating adhesion, corrosion resistance and longevity under cleaning/sterilization.
• Dimensional and geometric requirements: mirror diameter, curvature tolerances and edge safety.
• Mechanical strength: handle attachment, torque and bending resistance, and casing integrity.
• Hygiene and sterilization: materials and design compatible with common sterilization/cleaning methods.
• Test methods: standardized procedures for assessing optical quality, coating durability and mechanical performance.

Typical use and users

Used by dental practitioners and assistants for intra-oral visualisation, by dental instrument manufacturers during product development and quality control, by procurement teams specifying instruments for clinics, and by regulators and testing laboratories verifying compliance with dental device requirements.

Related standards

Standards commonly referenced alongside ISO 9873 include medical device quality and risk-management standards such as ISO 13485 (quality management systems for medical devices) and ISO 14971 (application of risk management to medical devices), which guide manufacturers on quality and risk processes for devices including dental instruments.
