🦷 Introduction to Using an Area-Specific Curette
The first paragraph introduces the design and use of an area-specific curette, which is semi-circular in cross-section with a rounded back and toe. This design enables its use both supragingivally and subgingivally. The curette has a single cutting edge per working end, with a face tilted at approximately a 70-degree angle to the lower shank. The instrument's curved cutting edges and rounded toe enhance its adaptation to tooth surfaces and root concavities. The paragraph also contrasts the area-specific curette with the sickle scaler or universal curette, emphasizing the different angles of the face in relation to the lower shank. The lower cutting edge of the area-specific curette is at the correct angulation when the lower shank is parallel to the tooth surface. The technique practice involves using the curette on the posterior sextant, beginning with the mandibular right first molar facial aspect. The paragraph emphasizes the importance of self-assessment of position and patient comfort, as well as the correct selection and use of the working end of the curette. It provides a step-by-step guide for inserting the curette, making controlled strokes, and ensuring adaptation to the tooth surface throughout the procedure.
📚 Technique Practice with Area-Specific Curette on Anterior Sextants
The second paragraph focuses on the technique for using an area-specific curette on anterior sextants. It discusses the importance of selecting the correct working end for the mesial surface of the central incisor. The correct working end is identified by the instrument's phase tilting toward the tooth surface, partially hiding the face. The technique practice involves placing the working end in the 'get ready' zone, sliding it beneath the gingival margin to the base of the pocket, and adapting the toe third of the cutting edge to the tooth surface. The paragraph provides instructions for making controlled strokes across the facial surface, maintaining adaptation, and ensuring that the strokes extend past the midline of the mesial proximal surface. It also highlights the effectiveness of horizontal strokes in removing calculus from specific areas of posterior teeth and the midlines of anterior teeth. The technique includes repositioning the curette and making oblique strokes across the facial surface, as well as using short controlled horizontal strokes across the midline of the facial or lingual surface.

Area-specific curettes are designed with a semi-circular cross section, rounded back and toe, allowing for both supra- and sub-gingival use.
Each working end of an area-specific curette has only one cutting edge, with the face tilted at approximately a 70-degree angle to the lower shank.
The curved cutting edges and rounded toe of the curette enhance adaptation to rounded tooth surfaces and root concavities.
The face of a sickle scaler or universal curette is at a 90-degree angle to the lower shank, with level cutting edges.
In contrast, the face of an area-specific curette is tilted, causing one cutting edge to be lower than the other on each working end.
The lower cutting edge of an area-specific curette is automatically at the correct angulation when the lower shank is parallel to the tooth surface.
When practicing the technique, first select the correct working end and establish a finger rest before insertion.
Ensure the lower shank is parallel to the tooth surface and the functional shank goes up and over the tooth for the correct working end.
Turn the toe of the working end toward the distal surface before placing it in the get-ready zone at the distal facial line angle.
Prepare for insertion by lowering the instrument handle to establish a zero-degree angulation.
Gently slide the working end beneath the gingival margin and onto the distal surface of the root.
Adapt the toe third of the working end to the distal surface of the root and imagine locking it against the tooth surface.
Make controlled strokes across the facial surface, ensuring each upward stroke is distinct and the grasp is relaxed.
Use horizontal strokes, which are extremely effective in removing calculus near the distal facial and lingual line angles of posterior teeth.
Insert the curette slightly distal to the distal facial line angle and begin a calculus removal stroke there.
Reposition the curette to continue making oblique strokes across the facial surface after several strokes.
When using an area-specific curette on anterior sextants, choose the correct working end by checking if the phase tilts toward or away from the tooth surface.
For anterior sextants, aim the toe of the working end toward the mesial surface and adapt the toe third of the cutting edge to the tooth surface.
Continue making controlled strokes across the mesial surface until at least halfway, maintaining adaptation with the instrument handle.
