●The history of periodontal instruments can be traced back to ancient civilizations, where teeth
cleaning was done using various tools such as twigs, feathers, and animal bones.
●Modern treatment, with illustrated text and sophisticated instrumentation, did not develop until the
time of Pierre Fauchard during the eighteenth century.
●In the 19th century, dental instruments began to be manufactured using metals such as silver and
stainless steel.
●The first periodontal instruments specifically designed for the treatment of periodontal disease were
developed in the early 20th century. These included the curette, a hand-held instrument used for
scraping plaque and tartar from the teeth, and the scaler, a tool used for removing calculus (hardened
plaque) from above and below the gumline.
●With the advancement in technology, periodontal instruments have become more specialized and
sophisticated, with ultrasonic and laser technology being used to aid in the removal of plaque and
tartar.

EARLY CIVILIZATIONS
●Oral hygiene was practiced by the Sumerians, the Babylonians, and the Assyrians (gingival massage,
herbal medication).
●The medical works of ancient India and China devote significant space to oral and periodontal
problems and oral hygiene (gingival inflammations, periodontal abscesses, gingival ulcerations).

THE CLASSICAL WORLD
●Among the ancient Greeks, Hippocrates of Cos (460 bc-377 bc), the father of modern medicine,
discussed the etiology of periodontal disease. He believed that inflammation of the gums could be
caused by accumulations of “pituita” or calculus, with gingival hemorrhage occurring in cases of
persistent splenic maladies.
●Paul of Aegina (625 ad-690 ad) wrote that tartar deposits must be removed with either scrapers or a
small file and that the teeth should be carefully cleaned after the last meal of the day.

THE MIDDLE AGES
●Albucasis (936-1013) described the techniques of scaling the teeth with the use of a set of instruments
that he developed, splinting loose teeth with gold wire and filing gross occlusal abnormalities.
●Avicenna (980-1037) was possibly the greatest of the Persian physicians. His Canon, a comprehensive
treatise on medicine, was in continuous use for almost 600 years. Avicenna used an extensive “materia
medica” for oral and periodontal diseases and rarely resorted to surgery.

THE RENAISSANCE
●Albucasis’ work was expanded during the fifteenth century by the Turkish author Serefeddin
Sabuncuoglu (1385-1468), who included illustrations of the surgical removal of hypertrophic and
swollen gingiva and lingual frenum. (A tube is placed on the gums and a hot cautery is inserted into the
cannula to cauterize the gingival tissue).
●The Frenchman Ambroise Paré (1509-1590) understood the etiologic significance of calculus and used
a set of scalers to remove the hard deposits on the teeth.

THE EIGHTEENTH CENTURY
●Modern dentistry essentially developed in eighteenth century Europe, particularly France and
England.
●Pierre Fauchard (Brittany, 1678) is regarded as the father of the dental profession. His book, The
Surgeon Dentist, which was published in 1728, covered all aspects of dental practice. Fauchard
described in detail his periodontal instruments and the scaling technique for using them.

THE NINETEENTH CENTURY
●Riggs and his disciples had great influence on the dental profession. Among Riggs’ followers were L.
Taylor, D.D. Smith, R.B. Adair, and W.J. Younger. The instruments designed by Younger and later
modified by his student Robert Good were used widely until well beyond the middle of the twentieth
century.

THE TWENTIETH CENTURY
●During the first third of the twentieth century, periodontics flourished in central Europe, with two
major centers of excellence: Vienna and Berlin.
●Neumann (1882-1958), in a book published in 1912 (with new editions in 1915, 1920, and 1924),
described the principles of periodontal flap surgery, including osseous recontouring as it is currently
known.

●HANDLE
●SHANK
●WORKING END
●The handle of the instrument is used for grasping the instrument.
●The design of instrument handles vary greatly from manufacturer to manufacturer. Presently, they are
available in various weights, diameters and textures (serrations).
○WEIGHT:
■The weight of the handle is determined by its diameter and core (solid or hollow).
■Hollow handles increase tactile sensitivity and minimize muscle fatigue.
■Solid handles reduce tactile sensitivity and increase muscle fatigue.
○DIAMETER:
■Small handles decrease control and increase muscle fatigue.
■Large handles maximize control and reduce muscle cramps but restrict movement in areas where access
is limited (posterior areas).
○SERRATION
■Serrated knurled handles maximize control and decrease hand fatigue.
■Smooth handles decrease control and increase fatigue.
●Thus, handles with small diameter, solid metal core and smooth texture are generally avoided.

●Shank connects the handle to the working end and allows adaptation of the working end to the on
the tooth surface.
●Shank can be functional or terminal.
○The functional shank extends from the working end to the shank bend closest to the instrument handle.
■It can be short, long or intermediate.
■Long functional shanks are needed to reach the tooth surfaces of posterior teeth or the root surfaces of
teeth within periodontal pockets.
■Short functional shanks are found on instruments used to remove supragingival calculus deposits or to
reach the surfaces of anterior teeth.
○The terminal shank extends between the blade and 1st bend.
●Shank can be either curved or straight.
○Curved shanks are used on both posterior and anterior teeth (universal instruments).
○Straight shanks are limited to use on anterior sextants (anterior instruments).
●Shank can be flexible, moderately flexible or rigid in design.

SHANK FLEXIBILITY RELATED TO INSTRUMENT USE
●The working end does the work of the instrument.
●The working end or blade is made up of several components such as the face, cutting edge, back and
toe/tip.
○A rounded working end is called toe whereas a pointed working end is called tip.
●The instrument may be single-ended or double-ended.
○Single-ended instruments reduce motion economy.
○Double-ended instruments provide efficient time utilization and motion economy.
○The working ends of a double-ended instrument may be paired or unpaired.
■Double-ended instruments with working ends that are mirror images of each other have paired working
ends, while instruments with two dissimilar working ends have unpaired working ends.

●The diagnostic mouth mirror, also known as the dental mirror, is a small handheld instrument that
dentists and hygienists use to reflect light into the patient's mouth to view hard-to-see areas.
●The evolution of the diagnostic mouth mirror can be traced back to the early 20th century, when
mirrors were first introduced in dental practice. Initially, mirrors were made of metal, such as silver or
stainless steel, and were relatively simple in design. Overall, the evolution of the diagnostic mouth
mirror has been driven by the need to improve visibility and access to hard-to-see areas of the
patient's mouth, as well as to make the instrument more comfortable and durable for the practitioner
to use.

●RECENT ADVANCES:
○In the 1940s, plastic handles were introduced, making the instrument more comfortable to hold and
easier to maneuver in the patient's mouth.
○The reflective surface of the mirror also evolved, with the introduction of glass mirrors coated with a
layer of metal, such as gold or chrome, to improve visibility and reduce glare.
○In the 1960s, fiber-optic technology was introduced, which greatly improved the visibility of the mirror,
as it allowed light to be directed into the patient's mouth with greater precision. This technology also
made the instrument more durable and resistant to corrosion.
○Today, diagnostic mouth mirrors come in a variety of designs and materials, including lightweight
aluminum handles and mirrors with a non-glare coating for improved visibility.
○Some mirrors are even equipped with LED lights to provide additional illumination.

Dental Mirror is a versatile tool in the world of dentistry,
but the problem is the characteristic of conventional
dental mirror that’s always faced by dentists in general is
mirror surface which is very vulnerable to get dirty due to
the debris or water droplet. A tool used for cleaning debris
or water droplets in dental mirror is by using dental
syringe that can spray water and air spray.
The “Three In One Dental Mirror” is able to prevent debris
or water spray that stains the surface of the dental mirror
so, that the use of the tool can be maximized without
additional procedures that will take up time time such as
cleaning the surface glass.
This instrument is a combination of three dental
instruments which are put together as one instrument so
that it has three functions. The function of this tool
specifically is to see the condition of the oral cavity which
is difficult to see directly which is equipped with an
operator lamp component to provide illumination in the
oral cavity as well as a syringe component to clean and
rinse mirror surfaces that are affected by debris
(treatment residual) or splashes of water droplets.

●Probe is a latin word, which means “to test”.
●A periodontal probe is used to accurately locate, assess and measure the sulcus and pocket depth.
●RATIONALE:
○To detect and measure loss or gain of clinical attachment level
○To determine the extent of previous or ongoing periodontal disease activity
○To assess the efficacy of the treatment done
●Ideally, these probes are thin and the shank is angled to allow easy insertion into the pocket. When
measuring a pocket, the probe is inserted with firm, gentle pressure to the bottom of the pocket. The
shank should be aligned with the long axis of the tooth surface to be probed.
●Presently, various periodontal probes are available which vary in their markings, colour coding,
diameter, material and angle.

●The typical periodontal probe is a tapered, rodlike instrument calibrated in millimeters, composed of a
blunt, rounded tip, shank and handle.
● The basic uses of the calibrated periodontal probe are:
○Measurement of the probing depth of a sulcus or periodontal pocket
○Determination of the topography of the junctional epithelium
○Determination of the probing level of the attachment
○Measurement of the width of the attached gingiva
○Assessment of bleeding points
○Measurement of the size and/or depth of an oral lesion

●HISTORY OF PERIODONTAL PROBES:
○The periodontal probe was first described as a periodontal diagnostic instrument by John W Riggs in
1982.
○The diagnosis of pyorrhoea by measuring pocket depths using a periodontal probe was described by F V
Simonton in 1925. He emphasized that the presence of pyorrhoea and its extent could only be
determined by the presence and depths of periodontal pockets.
○The first systematic classification of periodontal probes was given by B L Pihlstrom in 1992, who
classified the probes into 3 generations:
■FIRST GENERATION PROBES: conventional or manual probes which do not have pressure or force
measuring device attached to them
■SECOND GENERATION PROBES: pressure sensitive probes which allow standardization and
quantification of pressure during probing
■THIRD GENERATION PROBES: automated probing systems where along with a constant pressure
application, the data is stored by the computer

●SECOND GENERATION PERIODONTAL PROBES
○To overcome the lack of standardization of pressure applied in first-generation probes, second
generation probes were developed to standardize and quantify the pressure used during probing.
○Pressure sensitive, probing pressure should not exceed 0.2N/mm

○History:
■Gabathuler and Hassell (1971) designed the 1st pressure sensitive probe with a constant force
application.
■Another pressure sensitive probe holder was designed by Armitage in 1977.
■Tromp et al. (1979) introduced a pressure-sensitive probe in which a torque spring was attached to a
loose probe head that could rotate in a point bearing. They achieved a constant force application of about
15gms which was independent of the force applied by the operator.
■Vitek et al. (1979) introduced leaf spring force-controlled periodontal probe which delivered a force
within 0.5gms to Michigan ‘O’ probe tip.
■Polson et al. (1980) introduced electronic pressure sensitive probe, also known as Vine Valley Probe.

used to assess:
○Subgingival deposits
○Necrotic cementum
○Smoothness of root surface after root planing
○Carious and decalcified lesions
○Defective margins on restorations
○Tooth surface irregularities
●The pointed working end (explorer tip) is 1-2mm in length
●Explorers are made up of flexible metal which helps in better tactile sensation when the instrument is
moved on the tooth surface. Only light exploratory strokes are applied to evaluate the surface
smoothness.

ADVANTAGES AND DISADVANTAGES OF MECHANIZED INSTRUMENTS COMPARED WITH MANUAL INSTRUMENTS 66
INDICATIONS, PRECAUTIONS, AND CONTRAINDICATIONS FOR USE OF MECHANIZED INSTRUMENTS 67
●Various physical factors play a role in the mechanism of action of power scalers:
○frequency
○stroke
○water flow
○physiologic effects of water
●Water contributes to three physiologic effects that play a role in the efficacy:
○Acoustic steaming is unidirectional fluid flow caused by ultrasound waves.
○Acoustic turbulence is created when the movement of the tip causes the coolant to accelerate,
producing an intensified swirling effect. This turbulence continues until cavitation occurs.
○Cavitation is the formation of bubbles in water caused by the high turbulence. The bubbles implode and
produce shock waves in the liquid, thus creating further shock waves throughout the water

●Gracey Curvettes comprise a set of four mini-bladed curettes:
○the Sub-0 and #1-2 are used for anterior teeth and premolars
○the #11-12 is used for posterior mesial surfaces
○the #13-14 is used for posterior distal surfaces
●The blade length is 50% shorter than that of the conventional Gracey curette,
and the blade is curved slightly upward.
○allows Gracey Curvettes to adapt more closely to the tooth surface than any
other curettes, especially on the anterior teeth line angles
● However, this curvature also carries the risk of gouging or “grooving” into the
root surfaces on the proximal surfaces of the posterior teeth when #11-12 or
#13-14 is used.
●Additional features are a precision-balanced blade tip in direct alignment with
the handle, a blade tip perpendicular to the handle, and a shank closer to parallel
with the handle.

#13-14 is used.
●Additional features are a precision-balanced blade tip in direct alignment with
the handle, a blade tip perpendicular to the handle, and a shank closer to parallel
with the handle.

●Quétin furcation curettes are actually hoes with a shallow,
half-moon radius that fits into the roof or floor of the furcation.
●The curvature of the tip also fits into developmental
depressions on the inner aspect of the roots.
●The shanks are slightly curved for better access, and the tips
are available in two widths.
○The BL1 and MD1 instruments are small and fine, with a
0.9-mm blade width.
○The BL2 and MD2 instruments are larger and wider, with a
1.3-mm blade width.
●These instruments remove burnished calculus from recessed
areas of the furcation and lessen the likelihood of root damage.

●Used for final finishing of root surfaces
○can produce a smooth, even, clean, and highly polished root surface
●Do not have cutting edges; instead, they are coated with very fine-grit diamond
●Sharply abrasive and should be used with light, even pressure against the root surface to avoid gouging
or grooving
●Diamond files must be used carefully because they can cause overinstrumentation of the root surface.
They will remove too much root structure if they are used with excessive force, are poorly adapted to
root morphology, or are used too long in one place.
●Diamond files are particularly effective when used with the dental endoscope, which reveals residual
deposits and directs the clinician to the exact area for instrumentation.

●CONSIDERATIONS FOR ULTRASONIC INSTRUMENTS:
○Ultrasonic instrumentation is accomplished with a light-to-moderate grasp and varying
pressure depending on the amount and tenacity of the deposit. Excessive pressure can
cause dampening of the vibration of the tip.
○The tip should be kept in constant motion and parallel to the tooth surface, gouging and
roughening of the root surface or overheating of the tooth can occur.
○The ultrasonic tip must come in direct physical contact with calculus to fracture and
remove it. The tip must also contact all aspects of the root surface to remove biofilm and
toxins thoroughly. Although as much as 10 mm or more of the length of the ultrasonic tip
vibrates, only the terminal few millimeters (1-2mm) of the tip produce maximum vibration.
○Immediately after instrumentation, the tooth surfaces should be carefully inspected
visually with optimal lighting and the aid of a mouth mirror and compressed air; surfaces
also should be examined with a fine explorer or probe.

●CONSIDERATIONS FOR ULTRASONIC INSTRUMENTS:
○Ultrasonic instrumentation is accomplished with a light-to-moderate grasp and varying
pressure depending on the amount and tenacity of the deposit. Excessive pressure can
cause dampening of the vibration of the tip.
○The tip should be kept in constant motion and parallel to the tooth surface, gouging and
roughening of the root surface or overheating of the tooth can occur.
○The ultrasonic tip must come in direct physical contact with calculus to fracture and
remove it. The tip must also contact all aspects of the root surface to remove biofilm and
toxins thoroughly. Although as much as 10 mm or more of the length of the ultrasonic tip
vibrates, only the terminal few millimeters (1-2mm) of the tip produce maximum vibration.
○Immediately after instrumentation, the tooth surfaces should be carefully inspected
visually with optimal lighting and the aid of a mouth mirror and compressed air; surfaces
also should be examined with a fine explorer or probe.

●DISADVANTAGES OF PERIO-ENDOSCOPY SYSTEM:
○Cost: Perio-endoscopy equipment can be expensive and may not be available in all dental
clinics. The cost of purchasing and maintaining the equipment can also be a barrier for
some practitioners.
○Technical difficulties: Perio-endoscopy requires a certain level of technical skill and
training to use effectively. This can be a disadvantage for practitioners who are not
familiar with the system and its use.
○Limited accessibility: The design of perio-endoscopy systems can limit access to certain
areas of the mouth, particularly in cases of severe crowding or dental malocclusion.
○Uncomfortable for patients: The insertion of the endoscope into the periodontal pockets
can be uncomfortable for some patients and may cause gagging or other unpleasant
sensations.
○Limited diagnostic information: While perio-endoscopy provides valuable diagnostic
information, it is not a substitute for other diagnostic tests and should be used in
conjunction with other diagnostic tools.

●CONSIDERATIONS FOR CLEANING AND POLISHING INSTRUMENTS:
○Selection of appropriate instruments
○Proper technique: The technique used to polish teeth should be gentle and controlled,
avoiding excessive pressure that could damage the teeth or surrounding tissues.
○Patient comfort: Patients should be informed about the procedure, and appropriate
measures should be taken to minimize discomfort, such as using a topical anesthetic or
taking breaks during the procedure as needed.
○Monitoring for adverse effects: The practitioner should regularly monitor the patient for
adverse effects during and after the polishing procedure, such as sensitivity, irritation, or
pain.
○Post-polishing care: Patients should be instructed on proper post-polishing care,
including avoiding highly abrasive or acidic foods and drinks, brushing and flossing
regularly, and visiting the dentist for regular check-ups.
○Regular evaluation

In conclusion, periodontal instruments play a crucial role in the diagnosis, treatment, and maintenance
of periodontal health. From diagnostic tools, such as mouth mirrors and periodontal probes, to
therapeutic instruments, such as curettes, scalers, and ultrasonic devices, there are a wide range of
instruments available to help dental professionals diagnose and treat periodontal conditions.
Periodontal instruments must be selected and used appropriately to achieve the best outcomes, and
they should be regularly maintained and sterilized to minimize the risk of cross-contamination.
Additionally, dental professionals should have a good understanding of the indications, techniques, and
potential complications associated with each type of periodontal instrument to ensure that they are
used safely and effectively.
