The Karlin Style Curette, featuring a 9.5-inch length and a 2.7mm angled-up blade, is an essential instrument for periodontal scaling, root planing, and subgingival calculus removal. The angled-up blade is specifically designed to provide superior access to deep periodontal pockets and interproximal spaces, facilitating the efficient removal of calculus and debris in areas that are difficult to reach with traditional instruments.
