Cognitive science:
is a research area that draws on
several fields (such as
psychology, artificial intelligence,
linguistics, and philosophy) to
develop theories of perception,
thinking, and learning.
Cognitive science relates to
information science as we try to
understand how information is
represented in the human mind.
Computer science relates to
information science as try to
simulate our mental processes in
computing environments.

using a CAM technology
(such as a CNC milling
machine, or 3D printer). The
chairside systems are

31. Virtual Patients
31
The Virtual Dental Patient (VDP) application
was designed to aid dentists in getting
acquainted with the teeth anatomy, the
handling of drilling instruments and the
challenges associated with the drilling
procedure.
The VDP simulator allows the user to :
view/manipulate a 3-D head and oral cavity
model constructed using anatomical data,
adapt the model to the characteristics of
specific patient using either facial photographs
or 3D data,
animate it using an MPEG-compatible facial
animation player and
perform virtual tooth drilling within the oral
cavity using a Phantom haptic device to
control the drilling tool.
Drilling is performed on 3D
volumetric/surface models of teeth, obtained
from cross sections of real teeth.

32. Manikin-based simulators
32
DentSim™, consists of a
manikin with head and
dentoform (plastic teeth), a
dental hand-piece and a light,
an infrared camera and two
computers. The manikin head
and the hand-piece contain
infrared emitters that are
tracked by the infrared
camera. Using this optical
tracking system to trace the
movements of a hand piece,
the simulator scores the
accuracy of a student's cavity
preparation in a manikin’s
synthetic tooth.

Image Guided Implantology
(IGI), for teaching, diagnosis,
treatment planning and
placement of implants.
Providing a particular
patient’s CAT scan, the
simulator allows the patient
and the virtual model image
to be coordinated during the
actual surgery. If the
computer recognizes that the
surgeon is making a serious
deviation from the treatment
plan during the actual
surgery, the computer will
stop the hand-piece and the
surgeon will need to override
the computer to continue.

35. Haptic Devices
35
Virtual Reality Dental Training System
(VRDTS).
Aiming for cavity preparation, the software
simulates a set of dental instruments.
Using VRDTS dental students work with a
virtual decayed tooth and learn to probe it for
diagnosis, use a drill to prepare a tooth for
cavity repair, fill the prepared cavity with
amalgam and carve the amalgam to match
the original tooth contour. Unlike plastic
teeth, VRDTS enables the student to feel the
difference between enamel, dentin, caries,
amalgam and pulp throughout the
procedure.
The student's operation can be tracked
precisely in real time, providing quantifiable
feedback to both student and teacher.
Lastly, since the entire process is virtual, the
student has the ability to zoom, rotate and
even cut the tooth in cross section to better
understand the process. VRDTS offers the
student the opportunity to practice
procedures as often as needed, with no
additional cost for materials.

shown in real-time, and the user can adjust
the model position, viewpoint and
transparency level.
The system allows instructors to create short
scenarios of periodontal procedures, which
can be saved and replayed at any time. The
3-D component permits students to replay
from any angle, so the user can observe
different views of the placement of the
instrument and gingival relationships during
a procedure, Steinberg said.
The recorded file is an actual representation
of the original scenario, which offers great
training potential.

Reference management software, citation
management software or personal
bibliographic management software is
software for scholars and authors to use for
recording and utilizing bibliographic citations
(references).
Once a citation has been recorded, it can be
used time and again in generating
bibliographies, such as lists of references in
scholarly books, articles and essays.
Searching Dental E Sources- EM Al-Madi Oct-2012
75. 75
Reference management software collects a much
smaller database, of the publications that have been
used or are likely to be used by a particular author or
group, and such a database can easily be housed on
an individual's personal computer.
