Study Notes
Sickle Scaler Function
- Designed to remove supragingival calculus (hardened plaque) from tooth surfaces.
- Utilizes a sharp, curved blade to scrape calculus deposits away.
Thick Diameter Functional Shank Significance
- Provides strength and stability during use, minimizing the risk of bending or breaking.
- Helps control the instrument's movement and prevents excessive pressure on the tooth.
Sickle Scaler Cross-Sectional Shape
- Triangular or semi-circular.
- This shape facilitates adaptability to tooth surfaces, enabling effective calculus removal.
Contra-Angled Shank Areas of Usefulness
- Posterior teeth (molars and premolars), due to their limited accessibility.
- The angle allows for better visualization and manipulation of the instrument in these areas.
Periodontal Instrument for Light Deposits and Root Planing
- Universal curette is ideal for removing light deposits and root planing.
- It features a rounded back, which prevents damage to the soft tissues surrounding the tooth.
