What is the main difference between a scaler and a curette in periodontal instrumentation?
Show answer and explanation
Correct answer: Scalers are used supragingivally; curettes are safe subgingivally
Scalers typically have triangular cross-section with pointed tips and are meant for supragingival calculus removal. Curettes have a rounded back and toe, making them suitable for subgingival scaling and root planing without damaging soft tissue.
