4. INTRODUCTION
• DENTAL CARIES:- Acc to Shafers in 1993
Dental caries is an irreversible microbial disease of the calcified
tissue of the teeth, characterized by demineralization of inorganic portion and
destruction of organic substance of tooth which often leads to cavitation.
• Risk assessment is based on past caries experience, Socioeconomic
factors & biological factors.
• To identify who will most likely develop dental caries
• Provide these individuals proper preventive & treatment measures

5. CARIES RISK PREDICTORS & INDICATORS
Per Axelson. Diagnosis and risk
predicion of dental caries.
5
Predictors
• Key Age Groups
• Risk Individuals
• Key risk teeth
• Key risk surface
Indicators
• White spots
• Caries
• Enamel lesion
• Restorations˃ 3 years
6. CARIES RISK ASSESSMENT
• Can be defined as procedure to predict future dental
caries development before the clinical onset of disease.
•
• Determines caries incidence i.e number of new cavitated
or incipient lesions.
• Involves probability that there will be change in size or
activity of lesion.

7. • Risk assessment:
1. fosters the treatment of the disease process
instead of treating the outcome of the disease.
2. gives an understanding of the disease factors for a
specific patient and aids in individualizing preventive
discussions.
3. individualizes, selects, and determines frequency
of preventive and restorative treatment for a patient.
4. anticipates caries progression or stabilization

• Caries-risk assessment models currently involve a
combination of factors including diet, fluoride exposure, a
susceptible host, and microflora that interplay with a
variety of social, cultural, and behavioral factors.
10. 1. Caries questionnaire in combination
with clinical observation
• Featherstone et al. evolved a consensus statement to
assess individual caries risk from a questionnaire that
addresses issues such as maternal dental history, family
dynamics, socioeconomic factors, oral hygiene measures,
fluoride exposure, and frequency of sugar exposures.
• clinical observations were made by visual, tactile, and
radiographic examination of teeth.

A cariogram model
was used to create
caries risk profiles
on 499 children
aged 5 and 12 years
±6 months. They
were divided into 2
groups. The group I
and group II
consisted of 250 and
249 children
respectively. Re-
examination was
done after 1 year
and caries increment
was recorded. The
caries risk profiles
generated by the
cariogram software
The risk of
developing new
carious lesions
consistently
reduced from high-
risk category to
low-risk category,
reflecting the
cariogram ability in
accurately
estimating future
caries. Hence,
cariogram can be
said to be a useful
tool for caries
prediction.

40. Fosdick calcium dissolution test
Action: The test measures the milligrams of powdered
enamel dissolved in 4 hours by acid, formed when the
patients saliva is mixed with glucose and powdered
enamel.
Equipment: Powdered human enamel, saliva collection
bottles, sterile test tubes, test tube agitation equipment
and equipment for determining the calcium content of
saliva.
Nemmarugommula N, Arun A, Mythri H. Caries Activity Tests. Research and Reviews:
Journal of Dental Sciences 2013.
41. Procedure
• 2.5ml of stimulated saliva are collected, one part of this is analyzed for
calcium content, the rest is placed in an 8 inch sterile test tube with
about 0.1g of powdered human enamel.
• The tube is sealed and shaken for 4 hours at body temperature after
which it is again analyzed for calcium content.
• The chewing of gum to stimulate saliva produces sugar. If paraffin is
used, a concentration of about 5% glucose is added. The amount of
the enamel dissolution increases as the caries activity increases.
Interpretation
• Amount of calcium increases, as the caries activity increases.
• Amount of dissolution increases, as the caries increases.

meter or color indicator.
The test measures the number of millilitres of acid
required to lower the pH of saliva through an arbitrary pH
interval, such as from pH 7.0 to 6.0 or the amount of acid or
base necessary to bring color indicators to their end point.
Equipment: Needed equipment includes a pH meter, titration
equipment, 0.05N lactic acid, 0.05N base, Paraffin, Sterile
glass jars containing a small amount of oil.
Nemmarugommula N, Arun A, Mythri H. Caries Activity Tests. Research and Reviews:

48. Procedure:-
• 10ml of stimulated saliva is collected under oil at least 1hr
after eating: 5ml of this are measured into a beaker.
• The pH of the saliva is adjusted to 7.0 by addition of lactic
acid or base.
• The level of lactic acid in the graduated cylinder is
recorded ,lactic acid is then added to the sample until a
pH of 6.0 is reached.

50. Cariostat test
A sterile cotton swab - run across the buccal surfaces of all
maxillary teeth present.
The cotton swab is then placed into the ampule supplied by
the manufacturer (2 ml of the culture medium).
Incubated for 48 hr at 37°C.
51. • The test medium’s color change was compared with four
reference tubes provided.
• Scored :
Dark blue (pH 7) = 0;
Green (pH 5.5) = 1;
Yellow-green (pH 4.5) = 2;
Bright yellow (pH 4) = 3.
52. Dentocult SM Strip mutans
• Mutans streptococci play an important role in the initiation
and progression of dental caries and they are considered
the primary cause of bacteriological caries.
• This bacterium thrives in the plaque that forms on the
surface of teeth.
• The earlier the colonisation of teeth occurs, the higher
the prevalence of dental caries.
Nemmarugommula N, Arun A, Mythri H. Caries Activity Tests. Research and Reviews:
Journal of Dental Sciences 2013.
53. Interpretation:
• Mutans streptococci adhere to the rough area of the strip
in proportion to their density in saliva. After incubation they
are visible as light to dark blue, raised colonies on the
rough area of the test strip.
Nemmarugommula N, Arun A, Mythri H. Caries Activity Tests. Research and Reviews:
Journal of Dental Sciences 2013.
54. ORATEST
• based on the rate of oxygen depletion by micro organisms.
• Under aerobic conditions the bacterial enzyme, aerobic dehydrogenase
transfers electrons or protons to oxygen.
• Once oxygen gets utilized by the aerobic organisms and an anaerobic
environment is attained, methylene blue [redox indicator] acts as an
electron acceptor and gets reduced to leucomethylene blue.
• The metabolic activity of the aerobic microorganism is reflected by the
reduction of methylene blue to leucomethylene blue.
• The test is based on rinsing the mouth with sterile milk which dislodges
the micro-organisms and also produces a substrate for their further
metabolism. The formation of leucomthylene blue can be easily
observed because of the white color of milk.
•
Nemmarugommula N, Arun A, Mythri H. Caries Activity Tests. Research and Reviews:
Journal of Dental Sciences 2013.
55. Conclusion
• Clinical variables especially past caries experience,
bacterial levels, sociodemographic variables are most
significant predictors of future dental caries
development.
• Caries risk assessment is goal of practitioners to
establish more efficient dental care delivery system.

58. INTRODUCTION
• Diagnosis is derived from Greek word ‘dia’ means- by
and ‘gnosis’ means knowledge.
• Dental caries is the most common disease in the world.
• Diagnosis is the process of identifying a disease by its
signs and symptoms and results of various diagnostic
procedure.
• The conclusion reached by this process is also called as
diagnosis.
Michele Baffi Diniz, Jonas de Almeida Rodrigues and Adrian Lussi (2012). Traditional and Novel Caries
Detection Methods, Contemporary Approach to Dental Caries, Dr. Ming-Yu Li (Ed.), ISBN: 978-953-51-
58
59. • Objectives of caries diagnosis are to identify those
lesions that require surgical treatment, those that require
nonsurgical (restorative) treatment, and those persons
who are at high risk for developing carious lesions.

60. IMPORTANCE OF DIAGNOSIS
• It is self evident that before preventive means can be intelligently
instituted or before curative or restorative procedures can be
restored to, it is first necessary to make a thorough diagnosis of a
case.
• The examination of the patient is, then, an important procedure and
should be considered carefully and thoroughly.
• It should include not only a close inspection of the teeth and
supporting structures, but also general inspection of patient.

Caries Detection Methods, Contemporary Approach to Dental Caries, Dr. Ming-Yu Li (Ed.), ISBN: 978-
953-51-0305-9, InTech.
61. CRITERIA FOR DIAGNOSIS
• For a robust gold standard 3 criteria should be fulfilled
1. Reproducible
2. Reflect the patho-anatomical appearance
3. Be independent of the diagnostic tests under assessment
• According to PITTS(1997)the ideal method for diagnosis of carious
lesions would be non-invasive and provide simple, reliable, valid,
sensitive, specific, and be based on biologic processes directly
related to the carious process

62. • It should also be affordable, acceptable, and allow early
implementation in both clinical practice and research
settings.
• Its use should promote informed and appropriate
preventive treatment decisions, enhancing long term oral
health.
62
63. TRADITIONAL METHODS
• Meticulous clinical examination
• Tactile examination
• Radiographic examination
• Tooth separation
• Dental floss
63Michele Baffi Diniz, Jonas de Almeida Rodrigues and Adrian Lussi (2012). Traditional and Novel Caries
Detection Methods, Contemporary Approach to Dental Caries, Dr. Ming-Yu Li (Ed.), ISBN: 978-953-51-
64. Meticulous clinical examination
• Careful examination of the teeth under clean and dry
conditions using good illumination may reveal visual
signs of caries like
1. Brownish discoloration of pit and fissure
2. Opacity beneath pit and fissures or marginal ridges
3. Frank cavitation of the tooth surface
64Jeffery B. Price. A Review of Dental Caries Detection Technologies. PennWell
Publications. June 2013.
65. • This method is based on a combination of light, mirror, and
gentle probing and is used in most epidemiologic surveys .
• Caries is diagnosed if the tooth meets the American dental
association criteria of softened enamel that catches the
explorer and resists its removal.
• Or allow the explorer to penetrate proximal surfaces under
moderate to firm probing pressure.

Detection Methods, Contemporary Approach to Dental Caries, Dr. Ming-Yu Li (Ed.), ISBN: 978-953-51-
66. RADIOGRAPHIC EXAMINATION
• Conventional, intraoral periapical and bitewing
radiographs are employed for diagnosis of dental
caries.
Bitewing radiographs have more diagnostic value because
• Interproximal caries
• Recurrent caries below proximal restoration
• Both maxilla and mandible in one film

73. • The latent image that is formed on photoconductive plate
is converted in to a positive image by a process known
as development in a processor unit.
• Here the image is developed using a liquid toner.
• The toner image on the plate surface is then dried and
lifted off the plate by means of transparent adhesive
tape.
• Lamination of the tape to a translucent backing material
fixes the image which is now ready to view.

• Introduced by Richard Webber
• Digitization- taking a picture of the radiograph using
high quality camera.
• This is fed to a computer imaging device called digitizer
.
75
76. • Two standardized radiographs produced with identical
exposure geometry are used.
• The first one is called the “reference image” and the
subsequent images are taken for comparison.
• The reference image is displayed on the screen over
which the subsequent images are superimposed
• The difference between the original and subsequent
images can be seen as dark areas.

81. 4. DIGITAL FIBEROPTIC TRANSILLUMINATION
• This is a digitized and computed version of the FOTI.
• DIFOTI can also be used to detect fractures, cracks, and
secondary caries around restorations.
• DIFOTI uses white light to trans illuminate each tooth
and to instantly create high-resolution digital images of
the tooth.

82. • It is based on the principle that carious tooth tissue scatters and
absorbs more light than surrounding healthy tissue.
• The light is then directed through the mouthpiece to a miniature
electronic charge coupled device CCD camera in the handpiece.
• The camera digitally images the light emerging from either the
smooth surface opposite the illuminated surface or the occlusal
surface.
• These images are displayed on a computer monitor in real time and
stored on the hard drive for easy retrieval for comparative review of
images over time.

83. 5. Diagnodent
• laser auto fluorescence technology
• instead of using blue light it uses red light of wavelength 655nm.
• This red light identifies caries as having an increased fluorescence
over sound tooth, whereas blue light highlights caries as a reduced
fluorescence compared to sound tooth.
• A reading is provided on a digital display accompanied by an audible
tone
• Higher the digital reading and pitch of the audible tone, greater the
potential for caries involvement of the dentinoenamel junction and
underlying dentine

84. • Diagnodent unit comprises a pen like device with a
detachable tips of different diameter
• The central core fiber running trough the pen grip and
the tip is the red laser, with surrounding fiber being
detectors to measure the returned fluorescence light

• The Conductance measurement were made between a
specially designed probe tip and a hand held connector
• The frequency of the device was of 25 Hz which was
able to produce a low current of 3 micro amperes
• The machine displayed a frowning face that indicated
extensive demineralization or smiling face indicated a
sound site

• The main disadvantage of this ECM is difficult
measuring procedure.
• Enamel cracks and hypo mineralized areas can give
false positive readings

• BENNEDICT-first person to observe the fluorescence in human
teeth
• He noted a differential fluorescence between sound and carious
enamel.
• The visible light with in the blue green region has been used for the
development of a sensitive method for the detection of caries at an
early stage
• The tooth is illuminated with a broad beam of a blue green light of
488nm wave length from an argon ion laser.
7. QUANTITATIVE LASER FLOURESENCE
90. • When the teeth are illuminated with high intensity blue
light, the resultant auto-fluorescence of enamel is
detected by an intraoral camera which produces a
fluorescent image.
• The emitted fluorescence has a direct relationship with
the mineral content of the enamel.
• Thus, the intensity of the tooth image at a demineralised
area is darker than the sound area.

DIAGNOSIS OF DENTAL CARIES. Journal of Evolution of Medical and Dental Sciences/Volume
91. • Incipient as well developed caries in enamel were
clearly visible as dark areas which contrasted with the
fluorescent surrounding
• Microradiographic analysis of the longitudinally ground
section of the tooth confirmed that the dark area in the
laser fluorescence corresponded to a demineralization of
the enamel
• This can also be used to image plaque and calculus, and
therefore be useful in identifying active caries.

92. Technique
The QLF device consists of the light source and the intraoral camera
The QLF technique is a 2-stage process. First, an image of the
toothmust be acquired with the intraoral camera (ccd) held in the hand.
Then, both qualitative and quantitative assessments of mineral loss are
obtained.
The enhanced contrast between sound and demineralized enamel
enables the clinician to identify areas of concern.

95. 8. ULTRASONIC IMAGING
• Ultrasonic imaging can be used to detect early caries on the smooth
surfaces.
• Here an ultrasonic probe is used to send and receive sound waves from the
surfaces of the tooth.
• Normal enamel produces -no echoes
Initial white spot lesions - weak surface echoes
cavitated areas -echoes of high amplitude.
• This method may be more sensitive than visual, tactile or radiographic
method for detecting early lesions.

96. Ultrasonic system is composed of a transducer (probe) & an ultrasonic
precision thickness gauge.
The contact transducer is of the right angle type with a 1.5mm tip
contact diameter, 11MHz nominal center frequency with a removable
plexiglass delay tip.
The delay line tip of the contact transducer is at a right angle so that it
could be inserted or used in restricted height areas.
These high frequency focused delay line transducers are compatible
with any ultrasonic instrument capable of displaying a return echo at
depths as minute as 0.010inches.
The useful range is from 0.010 to 0.25 inches approximately.

97. 9. CONE BEAM COMPUTATED
TOMOGRAPHY (CBCT)
• CBCT also called as dental volumetric tomography, cone-
beam volumetric tomography, dental CT, and cone beam
imaging.
• Initially developed for angiography in 1982 and subsequently
applied to maxillofacial imaging.
• The principal feature of CBCT is that multiple planar
projections are acquired by rational scan to produce a
volumetric dataset from which inter-relational images can be
generated.
97•Mital P, Mehta N, Saini A, Raisingani D, Sharma M. RECENT ADVANCES IN DETECTION AND
DIAGNOSIS OF DENTAL CARIES. Journal of Evolution of Medical and Dental Sciences/Volume
98. • Cone-beam scanners use a 2D digital array providing an area detector
rather than a linear detector as CT does. This is combined with a 3D X-
ray beam with circular collimation so that the resultant beam is in the
shape of a cone, hence the name “cone beam.”
• As CBCT requires only a single scan for capturing the necessary data
the time required for CBCT scanning is substantially less (< 30 sec).
• This technology has limitations related to the cone beam projection
geometry, detector sensitivity, and contrast resolution that produce
images that lack the clarity and utility of conventional CT images.

99. 10. RADIOVISUOGRAPHY(RVG)
• The very first system that was introduced in digital radiography in
dentistry was radiovisiography by Trophy in France in 1987.
• Digital radiography is a method of reproducing a radiographic image
using a technology sensor of solid-state, which are broken into
electronic pieces, and presented and stored as an image using a
computer.

100. • There are two advanced technologies that create digital images
without an analog precursor;
1. Direct digital images.
2. Semi direct digital images.
• Direct digital images are acquired using a solid-state sensor.
• The solid-state sensors are based on charge coupled device (CCD)
and complementary metal oxide semiconductor (CMOS) and
CMOS-active pixel sensor (CMOS-APS) based chips.
• Semidirect digital images are obtained using a phosphor plate
system.

101. 11. OPTICAL COHERENCE
TOMOGRAPHY
• OCT, creates cross sectional images of biological structures
using differences in the reflection of light
• It was first proposed by Huang et al for imaging the
biological tissue
• OCT uses reflections of near infra-red light to determine not
only the presence of decay but also the depth of caries
progression.
101•Mital P, Mehta N, Saini A, Raisingani D, Sharma M. RECENT ADVANCES IN DETECTION AND
DIAGNOSIS OF DENTAL CARIES. Journal of Evolution of Medical and Dental Sciences/Volume
102. • OCT uses light wavelength of which dictates the
scattering and therefore the depth of penetration of the
imaging technique
• Most of the OCT techniques described for imaging the
dental tissue have used wavelength 842-1310 nm. this
gives the imaging depth of 0.6 -2mm
102•Mital P, Mehta N, Saini A, Raisingani D, Sharma M. RECENT ADVANCES IN DETECTION AND
DIAGNOSIS OF DENTAL CARIES. Journal of Evolution of Medical and Dental Sciences/Volume
103. • OCT is based on the interference of light
• When a light beam is spilt into two and recombined , interference
produces a pattern , the intensity of which is determined by the level
of light in each beam
• OCT systems use super luminescent diodes as a light source , this
type of source produces light with a broad range of wavelength ,each
of which produce it’s inference pattern
• The intensity of the interference is a function of scattering caused by
the changes in tissue structures of the tooth
• Variation in scattering measured in relation to the depth from a single
point on the tooth surface is called an A- scan
103•Mital P, Mehta N, Saini A, Raisingani D, Sharma M. RECENT ADVANCES IN DETECTION AND
DIAGNOSIS OF DENTAL CARIES. Journal of Evolution of Medical and Dental Sciences/Volume
104. As two beams are produced from a light source
• 1. sample beam
• 2. reference beam
• Sample beam goes into the tooth and scattered according to the nature
of tissue so caries teeth scatters light to a greater extent than sound tooth
structure
• Reference beam travels to the moveable mirror and reflected back and
recombined with a sample beam
• The recombined reference and sample beam are focused on a photo
detector where any degree of interference between the beams can be
observed

105. 12. CARIES DETECTOR DYES
• Useful to aid the dentist in differentiation of infected dentin.
• They are non-specific protein dyes that stain the organic
matrix of less mineralized dentin, including normal circum
pulpal dentin and sound dentin in the area of the dentino-
enamel junction.
• Observation of colored dye signifies presence of caries.
Various dyes like Procion, calcein, brilliant blue, propylene
glycol have been used to detect enamel caries.

109. CO2 LASER
• Radiation of wavelength - 10.6 µm is used.
• Philosophy underlying application of carbon dioxide lasers is based on
assumption that subsurface layer of early carious lesions has more organic
content when compared with adjacent sound enamel.
• Photo-vaporization by a CO2 laser of this organic material in the incipient
carious lesions will leave a carbonized residue, which appears dark black.
• At low power levels & short duration times, inorganic substance of sound
enamel with minimum water content will be much less affected by laser
beam.

110. Conclusion
• It is clear from the above discussion that the differences
in caries presentations and behavior in different
anatomical sites make it unlikely that any one diagnostic
modality will have adequate sensitivity and specificity of
detection of carious lesions for all sites.
• A combination of diagnostic tools will help us diagnose
lesions earlier and detect failing restorations sooner, all
to avoid more costly, destructive dental procedures and
truly take dentistry into the preventive rather than the
reactive mode.
