Scalers and curettes are dental instruments used for the removal of dental plaque, calculus (tartar), and other deposits from the teeth and gums. These instruments are commonly employed in dental cleanings (prophylaxis) and periodontal treatments to maintain oral health and prevent gum diseases. Scalers and curettes come in various designs and are essential tools for dental hygienists and dentists. Here’s an overview of scalers and curettes:
Scalers:
Design:
Scalers have pointed tips with a curved or angled design. The tips are sharp and are used to remove hard deposits such as calculus from the tooth surfaces.
Function:
Scalers are designed to be used supragingivally, which means above the gumline. They are effective in removing calculus and plaque from the enamel surfaces of the teeth.
Types of Scalers:
Universal Scalers: Versatile scalers that can be used on all tooth surfaces.
Area-Specific Scalers: Designed for specific areas of the mouth, such as mesial, distal, buccal, or lingual surfaces.
Jacquette Scalers: Have a shorter, thicker blade and are used for heavy calculus removal.
Uses:
Scalers are effective in removing calculus, plaque, and stains from the tooth surfaces. They are commonly used in the early stages of dental cleanings.
Curettes:
Design:
Curettes have a rounded or semicircular shape with a rounded toe. The working end is curved, allowing for adaptation to the tooth surface and root.
Function:
Curettes are designed for subgingival use, reaching below the gumline. They are used to remove calculus and plaque from the tooth surfaces and root surfaces within the periodontal pockets.
Types of Curettes:
Universal Curettes: Versatile curettes used on all tooth surfaces.
Gracey Curettes: Designed for specific quadrants of the mouth, with different blade designs for mesial or distal surfaces.
Uses:
Curettes are particularly effective in cleaning and scaling below the gumline in periodontal pockets. They are crucial for treating gum diseases like periodontitis.
Differences:
Location of Use:
Scalers are primarily used above the gumline (supragingival), while curettes are designed for use below the gumline (subgingival).
Tip Shape:
Scalers have pointed tips for removing hard deposits, while curettes have a rounded toe for effective subgingival adaptation.
Application:
Scalers are often used initially in dental cleanings to remove large deposits, followed by the use of curettes for more detailed subgingival scaling in periodontal pockets.
Versatility:
Scalers are versatile and can be used on all tooth surfaces, while curettes may have specific designs for different areas of the mouth.
