SIST EN ISO 13397-2:2005/A1:2013 PDF

Overview

EN ISO 13397-2:2005/A1:2012 is a CEN-adopted amendment to the international standard for dental instruments titled Dentistry - Periodontal curettes, dental scalers and excavators - Part 2: Periodontal curettes of Gr‑type. Amendment A1 (2012) adds guidance on colour coding for a reduced set of Gr‑type periodontal curettes to improve instrument identification and clinical workflow. The amendment was prepared by ISO/TC 106 (Dentistry) and approved by CEN in 2012.

Key topics and technical requirements

• Scope: Applies specifically to Gr‑type periodontal curettes within the ISO 13397‑2 framework.
• Colour coding guidance: Provides a recommended colour scheme (manufacturer’s discretion) for a reduced set of Gr‑type curettes to indicate intended tooth positions/areas.
• Suggested mapping (Table 3):
  • Gr 5 & Gr 6 - Yellow: Anterior and premolar teeth
  • Gr 7 & Gr 8 - Green: Molar and premolar teeth, buccal and lingual/palatal aspects
  • Gr 11 & Gr 12 - Red/Orange: Molar and premolar teeth, mesial surfaces and furcations
  • Gr 13 & Gr 14 - Blue: Molar and premolar teeth, distal surfaces and furcations
• Implementation note: The colour coding is advisory and left to the manufacturer’s discretion; the amendment supplements EN ISO 13397‑2:2005 rather than replacing it.
• Regulatory/administrative: The amendment was to be adopted into national standards by April 2013 across CEN member countries; users should be aware of possible patent rights related to instrument designs.

Practical applications and users

• Dental instrument manufacturers: Implement consistent colour marking schemes on Gr‑type curettes to align with market expectations and improve product usability.
• Dental clinics and hygienists: Use colour-coded curettes to speed instrument selection during periodontal therapy, reduce errors, and streamline tray setup.
• Dental schools and training programs: Teach students standardized instrument identification to improve ergonomics and clinical efficiency.
• Procurement and sterilization departments: Improve organization of instrument sets and tracking through standardized colour cues.
• Regulatory and standards professionals: Reference the amendment when specifying compliance requirements for dental equipment.
