What is ISO 22598 about?
ISO 22598 discusses colour tabs for intraoral tooth colour determination for dentistry. ISO 22598 outlines requirements for tooth-like colour representations made of ceramic materials used to determine the tooth colour in the patient’s mouth. Or to check the colour of dental prosthesis, which are referred to as colour tabs in ISO 22598.
Colour tabs for intraoral tooth colour can be manufactured from any materials and serve solely to illustrate the colour effect; they do not serve to determine colour inside the mouth.
Note: Resources for visualizing the colours of ceramic and other masses, e.g., mass shade guides and colour patterns for certain ceramic and other masses, do not fall into the scope of ISO 22598.
Who is ISO 22598 for?
ISO 22598 on colour tabs for intraoral tooth colour determination for dentistry is useful for:
- Manufacturers for intraoral tooth
- Medical laboratories for intraoral tooth
- Regulatory authorities
Why should you use ISO 22598?
In dentistry, colour matching, colour communication among dentists and dental technicians (indirect restorations), colour reproduction and verification are essential elements for a successful aesthetic restoration.
ISO 22598 guideline provides requirements on material, processing, appearance, uniformity, cleaning, disinfection, and colour stability. ISO 22598 provides test methods on the positioning of the colour tab, measurement parameters to be set, and the number of measurements for colour measurement. This helps in the successful aesthetic restoration and fulfils other appearances such as opacity, gloss, opalescence, and fluorescence of tooth colour.
