Overview
SIST EN ISO 13397-2:2005 is an international standard developed by ISO/TC 106 and CEN/TC 55, specifying the designs and dimensions for Gr-type periodontal curettes used in dentistry. This standard defines the precise characteristics of these specialized dental instruments to ensure uniformity, safety, and effectiveness in periodontal treatments. It supersedes the previous 1996 edition, introducing updates such as the addition of new Gr-type curettes (Gr 15 to Gr 18) and clarifications on angles and surface specifications.
Gr-type periodontal curettes are hand instruments specifically designed for the debridement of periodontal pockets and root surfaces. The working ends feature a semicircular cross-section with sharp ground blades tailored for precise root surface treatment.
Key Topics
- Specification of Gr-type Curettes: EN ISO 13397-2 details the exact designs including blade shape, cutting edge, and angular relationships between key surfaces of the curette.
- Dimensions and Tolerances: The standard defines blade width, thickness, height, shank height, length to first bend, and radius of the blade’s curvature with precise measurement points and tolerances.
- Angles and Surfaces: It specifies the cutting angle (approximately 70° between the facial surface and the longitudinal axis of the shank), relief angle, and offset angle to optimize cutting efficiency and access to root surfaces.
- Types of Gr Curettes: The document covers Gr-types 1 to 18 with detailed illustrations and dimensions to accommodate different clinical needs.
- Measurement Methods: Guidance on how to measure and verify curette dimensions to maintain quality control and adherence to the standard.
- Terminology: Standardized definitions relevant to periodontal curettes, facilitating consistent communication among dental professionals and manufacturers.
Applications
SIST EN ISO 13397-2:2005 is essential for:
- Dental Manufacturers: Ensuring periodontal curettes meet international design and dimensional criteria to guarantee compatibility and quality.
- Dental Practitioners: Enabling selection of properly designed Gr-type curettes for effective periodontal therapy, including removal of plaque and calculus from root surfaces.
- Regulatory Authorities: Assessing the compliance of dental instruments with recognized standards to uphold patient safety.
- Educational Institutions: Teaching dental students about standardized instrumentation and its impact on periodontal treatment outcomes.
Using instruments conforming to this standard improves clinical efficacy, reduces the risk of instrument failure, and harmonizes production standards globally, fostering better dental hygiene and periodontal care practices.
Related Standards
This standard is part of the broader ISO 13397 series, which covers periodontal curettes, dental scalers, and excavators:
Additionally, it references:
- ISO 1942 - Dentistry vocabulary, providing standardized definitions critical for understanding dental instrumentation terminology.
Manufacturers and dental professionals should consider these related standards to ensure comprehensive compliance and optimum instrument selection.
By conforming to SIST EN ISO 13397-2:2005, stakeholders in the dental sector enhance the quality, reliability, and safety of Gr-type periodontal curettes, ultimately supporting better periodontal health outcomes worldwide.
