Universal curettes are designed so that it is possible to adapt the one instrument to all tooth surfaces by making use of both cutting edges on each blade. Area-specific curettes, such as the Gracey curettes, are designed so that each blade adapts to a specific tooth surface or area.

What are universal scalers?

Universal Curettes are used for the removal of supra and subgingival calculus. Barnhart curettes have universal blades with sharp cutting edges on both sides and a rounded toe.

What is the best universal curette?

Traditionally the most popular universal curette has been the Columbia 13-14. It is the shortest shank universal curette and very similar to a 204S scaler with a rounded toe instead of a pointed tip. While the Columbia 13-14 is still common, the Barnhart 5-6 has now become the most popular universal curette.

How many types of blades have universal curettes?

There are 9 types of traditional Gracey curettes. Each of them is designed to access particular areas of the mouth and particular surfaces of the teeth.

What is the Barnhart 5/6 used for?

Designed for the removal of moderate to heavy calculus from all supra- and subgingival tooth surfaces. These instruments remove moderate to heavy calculus from supra- and subgingival tooth surfaces. Put one of the cutting edges against the tooth.

How can you tell the difference between curette and Gracey?

Differences between Universal Curettes and Area Specific (Gracey) Curettes: The blade of Area-specific curettes are curved from head to toe and also along the side of the cutting edge. The Universal curettes are curved in one direction only.

What is the difference between a universal curette and a Gracey curette?

Universal curettes are designed so that it is possible to adapt the one instrument to all tooth surfaces by making use of both cutting edges on each blade. Area-specific curettes, such as the Gracey curettes, are designed so that each blade adapts to a specific tooth surface or area.

What is a Kirkland knife used for?

SMS Instrument Kirkland double end knife is a periodontal instrument for initial bevel incision for gingivectomy or gingivoplasty procedures. Especially effective in retro-molar region. For incisions that remove or recontour soft tissue. Also useful to excise interproximal tissue.

What is a Gracey 3/4 used for?

Area specific curettes for the removal of deep subgingival calculus. These area-specific curettes are for removing deep subgingival calculus and for finishing subgingival root surfaces. Put the tip third or half of the cutting edge against the tooth.

How many cutting edges does a universal curette have?

The blade of a universal curette has a round toe and back, and two cutting edges for scaling, making it an efficient design for scaling the entire mouth. Universal curettes are also available with rigid shanks in select patterns for moderate to heavy calculus removal.

Is a Barnhart 5/6 a universal curette?

PDT’s most popular universal curette, the Barnhart 5-6, features two cutting edges and a round toe for use on all surfaces. PDT instruments are ideally weighted, featuring the most ergonomic handle with knurling to the instrument shank to provide increased comfort with less hand fatigue and pinch.

Is a sickle scaler universal?

The strength and efficiency of sickle scalers have made them universally popular. New posterior sickle designs now provide clinicians with better choices for initial scaling but they should always be followed by curets to complete definitive instrumentation.

What is a Gracey 13 14 used for?

Gracey curettes are area specific instruments, designed for all types of calculus removal and root planing. With a rounded toe and only one cutting edge, Graceys have a “safe-side” for carefree deep periodontal cleaning. LM’s optimally contoured blade tips follow curved tooth morphology.

What Gracey curette is used for anterior teeth?

The Gracey 1/2 is designed for use on all aspects of anterior teeth (including canines). The instrument has a small contra-angle and a return angle resulting in an instrument toe which is close to the mid-line of the instrument handle for better stability.

What is the Gracey 17 18 used for?

The 17/18 Gracey Curette is designed to improve access to the distal surfaces of posterior teeth (Figure 15). The deep angle of the shank, along with multiple bends, provides crown clearance and prevents interference of the handle with the opposing arch and teeth.

Which of the following are design characteristics of a universal Curet?

• Face is perpendicular to the lower shank.
• Face off set at 70 to 80 degrees to lower shank.
• One cutting edge per working-end.
• Two cutting edges per working-end.

Where do I use Gracey curette?

These area-specific curettes are for removing deep subgingival calculus and for finishing subgingival root surfaces. Put the tip third or half of the cutting edge against the tooth. (The larger outer curve is always the cutting edge.)

What are area specific curettes?

(ār’ē-ă spĕ-sif’ik kyūr-ets’) Periodontal instruments used to remove calculus deposits from the crowns and roots of teeth. Each area-specific curette is designed for use only on certain teeth and certain surfaces. These curettes have long functional shanks; one working cutting edge is used for calculus removal.

What is hoe scaler?

For the removal of supra- and subgingival calculus. Suitable for deep, narrow pockets and concave root surfaces. For both vertical and horizontal techniques.

What Gracey curette is used for posterior teeth buccal and lingual surface?

The Gracey 7/8 curet is an area-specific curet that has a straight shank with an angle or bend. Its primary function is to remove soft and hard deposits along the buccal and lingual surfaces of the posterior teeth for patients with slight to severe periodontitis.

What is the Orban knife used for?

The unpredictability of current surgical procedures for papilla reconstruction has been a matter of concern for both periodontists and patients.

What is a Williams probe used for?

Williams Probe: It is also called the periodontal probe it is the first probe to be used to assess probing depth of a pocket, it has the following markings – 1,2,3,5,7,8,9,10 mm.

What is a Gingivectomy procedure?

A gingivectomy removes and reshapes loose, diseased gum tissue to get rid of pockets between the teeth and gums. A gum specialist (periodontist) or oral surgeon often will do the procedure. The doctor will start by numbing your gums with a local anesthetic. He or she may use a laser to remove loose gum tissue.

What does a Gracey curette do?

Gracey curettes are area-specific periodontal curettes made from stainless steel used to remove supra and subgingival calculus. … Gracey curettes are especially ideal for subgingival calculus removal because the design of the instrument allows for better adaptation to the anatomy of the roots.

Which of the following instruments has a universal blade with a Gracey design and a more rigid shank?

The Langer Curettes were designed to take the shank designs of the Gracey Curettes and combine them with the universal blade, thus allowing utilization of the same instrument for both mesial and distal surfaces. Langer Curettes have the following characteristics: Universal blade. Gracey shank design.

What kind of shank does a universal Curet have?

The Langer universal curet is designed with a universal blade but with the shank of a Gracey. This combination provides the operator with easy adaptation to difficult areas through the shank and two cutting edges for a more universal use around a tooth (Figure 3).
