The Karlin Style Curette, measuring 9.5 inches in length, features a 3.5mm angled-up blade with a #1 blade size (FA), making it an ideal instrument for subgingival scaling, root planing, and calculus removal in difficult-to-reach areas. The angled-up blade offers precise access to deep periodontal pockets and furcations, allowing the clinician to perform detailed cleaning and effective debridement.
