The Karlin Style Curette, at 9.5 inches in length, features a 2.7mm straight-down blade, engineered for subgingival scaling, root planing, and calculus removal in periodontal procedures. The straight-down blade allows for precise access to deeper periodontal pockets, making it ideal for root surface debridement and the removal of subgingival calculus with minimal trauma to the surrounding soft tissue.
