The Karlin Style Curette with a 9.5-inch length and a 3.0mm angled-up blade is designed for subgingival scaling, root planing, and calculus removal in periodontal therapy. The angled-up blade provides precise access to periodontal pockets and interproximal areas, allowing clinicians to effectively remove calculus and debris from difficult-to-reach regions around the root surfaces, particularly in posterior teeth or areas with curved roots.
