Periodontal scalers are dental instruments used in the prophylactic and periodontal care of teeth most often human teethincluding scaling and root planing. The working ends come in a variety of shapes and sizes, but they are always narrow at the tip, so as to allow for access to narrow embrasure spaces between teeth. They differ from periodontal curetteswhich possess a blunt tip. Together with periodontal curettesperiodontal scalers are used to remove calculus from teeth. While curettes are often universal in that they can be used on both supra- and sub-gingival calculus removals, scalers are restricted to supra-gingival use.
Scalers have scraping edges on both sides of their blades and thus are fit for both mesial and distal surfaces of any tooth in the area in which they are being used.
Scalers are best used when their terminal shank, namely, the last portion of the functional shank closest to the working end, is angled slightly toward the surface of the tooth. The composition of hand instruments are continuously evolving, which is why it may be a challenge to find the proper instrument for the right clinical situation.
With the continuous, evolving technology of hand instruments, it gives dental professionals the opportunity to implement dental treatment more effectively for the patient while improving their work surroundings simultaneously. Generally, there are two cutting edges per working end: the outer cutting edge farther from the instrument handle and the inner cutting edge closer to the instrument handle. Typically, periodontal scalers have pointed backs, but some new scaler designs have working ends with rounded backs as well.
3: Instruments and Instrumentation
When it comes to periodontal therapy, there are multiple steps that are required prior to activating a proper working stroke on the teeth. First, a modified pen grasp position must be achieved before starting periodontal instrumentation; this position involves the thumb and the index finger placed on the instrument handle, the middle finger resting on the shank, and the little finger neutral and relaxed near the ring finger.
In addition, there are several characteristics of a calculus removal stroke that are vital to the effectiveness of periodontal instrumentation;  these include stabilization, adaptation, angulation, lateral pressure, characteristics, stroke direction, and stroke number.
Once all these characteristics are understood, the clinician will activate the periodontal debridement strokes using the periodontal scalers. When performing periodontal debridement, the instrumentation of anterior teeth and posterior teeth are applied with the following steps. These instrumentation techniques are followed to achieve effective periodontal therapy using periodontal instruments,  such as periodontal scalers.

Miller Willoughby D. Miller Carl E. Endodontology Orthodontology Prosthodontology.The subgingival use of sickle scalers may be the best kept secret of dental hygiene practice.Camhi online
Most clinicians were taught to use sickles only supragingivally for gross calculus removal. It is not unusual, however, for many experienced clinicians to use all types of sickle scalers subgingivally for light as well as heavy scaling. During my lectures on periodontal instrumentation, I routinely ask audience members questions about sickle scalers.
First, I ask them to raise their hands if they were taught to use sickle scalers only supragingivally. Almost all raise their hands. Next, I ask how many now use sickle scalers subgingivally. Then, I ask if they use these sickles subgingivally as deep as they can possibly get them without traumatizing the tissue. So why are we all sneaking around in the secrecy of our operatories using sickles and hoping that no one will catch us? Excellent knowledge of root morphology and clinical experience are required to develop the ability to visualize the position of the sharp point of this potentially dangerous instrument, especially as it approaches the soft tissue attachment.
Once they gain this experience, many dental hygienists and dentists begin to use sickle scalers subgingivally because they discover that sickles can be more efficient at removing heavy calculus than curets. Therefore, many experienced clinicians routinely use sickle scalers first for heavy scaling or follow initial subgingival ultrasonic scaling with sickle scalers before finishing with universal or Gracey curets.
This angulation allows the strong sickle scaler blade to fracture the deposit cleanly away from the tooth. The calculus often breaks away from the tooth in visible chunks or pieces rather than being shaved or whittled away, layer by layer, from the tooth.
On the proximal surfaces of molars, the acutely angled shanks of posterior sickles allow the blades to engage the calculus with a more open angle than a Gracey curet.
These sickles are specifically designed for premolars and molars so they are safer and more efficient for subgingival calculus removal on the posterior teeth.
In recent years, several companies have introduced new posterior sickle designs that are becoming very popular in the United States and Canada. With a light, tactilely sensitive plastic handle and curved, mirror image blades, this scaler became a favorite of dental hygienists who were searching for a thin, sharp scaler to use on patients with light to moderate calculus.
InPDT, began to produce a new Rigid Montana Jack for heavier scaling that has larger shanks with blades that are as narrow as the original Montana Jack but thicker face to back Figure 1. The Hartzell MJ4 scaler is double ended with rigid, large, strong, curved blades that are ideal for scaling moderate to heavy subgingival calculus Figure 2.Related to sickle scaler: Gracey curette. An electronic circuit that records the aggregate of a specific number of signals that occur too rapidly to be recorded individually.
Electronics Also called: counter or scaling circuit an electronic device or circuit that aggregates electric pulses and gives a single output pulse for a predetermined number of input pulses.

Full browser?The objective of scaling is to remove calculus from the tooth surface. This is easy to accomplish when the calculus is located on the enamel of the tooth. Calculus attached to the root surface, however, is embedded in the surface irregularities and is much more difficult to remove. The dentist or hygienist will smooth out the irregularities and remove the calculus. As this is done, some root structure is removed. This is referred to as root planing. Several instruments have been designed for scaling and root planing.
They include sickles, curettes, files, chisels, and hoes illustrated in figure We will discuss dental implant scaling instruments.
A sickle scaler fig. Sickles with straight shanks are designed to adapt to anterior teeth, and those with contra-angled shanks called Jacquettes adapt to posterior teeth and are illustrated in figure The basic characteristics of the sickle scaler are they are triangular in shape, have two cutting edges, and are pointed at the tip.

After reading this chapter the reader should be able to identify the various types of instruments and have an understanding of the purpose of each periodontal instrument, and its advantages and disadvantages in different situations.
The instruments used for periodontal non-surgical management can be divided into of two main categories:. There are many groups of instruments that are used for scaling procedures. Each instrument is designed for use in a specific area of the mouth. An instrument can be categorised by:.
The chisel scaler is a straight instrument that curves slightly as the blade extends from the shank Fig It is available in different widths and is used with a controlled push stroke from the labial aspect of the lower anterior teeth to remove interproximal and lingual supragingival calculus.
It should only be used where there is sufficient embrasure space or gingival trauma will result. It may be used subgingivally where the interdental papillae have lost attachment.
A mouth mirror should always be used to protect the tongue and the floor of the mouth. Fig The chisel scaler is a straight instrument that curves slightly as the blade extends from the shank. The working end of trihedral scalers is triangular in cross-section Fig It is designed so that its lower border does not damage gingival tissue.
There are two blades, one either side of the superior surface, which end in a point. The blades curve in a lateral plane allowing them to engage the tooth surface. The shank may be straight or contra-angled. There are two main types of trihedral scalers: sickle scalers and jacquette scalers G3, G4, J1 and H5.
Sickle scalers H6 and H7 are principally used for the removal of supragingival calculus or for subgingival calculus that is located just below the gingival margin. Fig For lower anterior teeth a mini-sickle scaler has a tighter curve at the instruments working end.
The single blade is bevelled. Hoes can be used on all tooth surfaces and are primarily used for subgingival scaling and root surface instrumentation.Greek mythology assignment
It is important that a two-point contact is maintained Fig throughout the instrument stroke. Care must be taken to avoid gouging of the cementum with the corners of the blade. These instruments are difficult to sharpen, although tungsten carbide hoes are durable and require less frequent sharpening.
There are four instruments, which are designed to enable the mesial, distal, buccal and lingual surfaces to be instrumented TC,and We can customize any Cislak instrument.

Excess force is not only bad for the patient, but can contribute to serious hand, wrist, neck, shoulder, and back pain for the practitioner. Sharp instruments on the other hand save time, improve cutting ability, increase tactile sensitivity, reduce fatigue, and the list goes on…read more on our Dental Instrument Sharpening blog post.
To correctly sharpen scalers and curettes, it is important that you are able to identify them and their differences. Scalers have a sharp triangular tip and blades on both sides.Unitrunker 2 download
Because scalers have the sharp triangular tip, they can cause damage to the gingiva and should not be used below the gum line subgingivally.
Curettes are designed with a rounded tip and at least one edge that is not sharp for safely removing calculus subgingivally.Refrigeration hard start kit
They are also commonly used supragingivally due to the fact that they come in many shapes and angles designed for specific tooth surfaces and areas in the mouth. There are two types of curettes.
This makes the Gracey less versatile, but more efficient at removing subgingival calculus.
Instrument Organization: When purchasing new scalers and curettes it can be very helpful to use identification tape or rings link to instrument id collection to easily differentiate between scalers, and universal and gracey curettes.
Instrument ID systems will not only save you time while sharpening, but also during your dental procedures. Area-specific curettes are sharpened on an angle so one side of the blade is sharper than the other. The sharper side goes against the We can custom order any Cislak instrument.

Cislak P16 double-ended sickle scaler N Scalers have a sharp pointed tip unlike curettes which have a rounded Description Cislak P16 double-ended sickle scaler N Scalers have a sharp pointed tip unlike curettes which have a rounded toe.
Z-Soft These handles are made with colourful soft silicone grips combined with durable stainless steel and are fully autoclavable. CS A thinner and heavier handle option. The Cislak Way Cislak Manufacturing is the source for quality crafted dental hand instruments for the veterinarian. All Cislak instruments are made of the highest quality materials in the USA or Europe the only exceptions are noted.
Cislak has worked with a number of veterinary dental specialists to develop a line of instruments with specific veterinary needs in mind. Knowing the importance of being able to hold the instrument correctly, Cislak offers multiple handle choices to suit all customers. Cislak instruments also come with the added benefit of the ability to be re-tipped because they are manufactured in such a way that the handle and shank can be separated. Customers can then save the handles of any damaged or worn instruments and send them to Serona for re-tipping, rather than replacing them with new instruments at a higher cost.
Material failure is defined as any defect, pitting or corroding or breakage due to a fault in the steel or handle of an instrument. Any instrument found to have these types of defects will be repaired or replaced.
Scalers Scalers have a sharp triangular tip and blades on both sides. Curettes: Curettes are designed with a rounded tip and at least one edge that is not sharp for safely removing calculus subgingivally.
