12. Patient Dental Chair
The Dental Chair is a specially
designed medical device
intended to support a patient's
whole body, Adjustable,
comfortable, so that the
dentist can recline patients to
virtually any position
Also ensures patient comfort
even during long procedures.
14. Three-way or Air-Water
syringe
The air water syringe tip is
the item that is used to
spray air and water in a
patient's mouth during a
dental treatment. Due to
it's simplicity, a dentist
orthodontist, and hygienist
overlook the cross-
contamination ramifications
that can occur from not
properly sterilizing their
metal air water syringe tips
18. Radiography Unit
Dental radiographs are commonly called X-
rays. Dentists use radiographs for many
reasons: to find hidden dental structures,
malignant or benign masses, bone loss, and
cavities.
A radiographic image is formed by a controlled
burst of X-ray radiation which penetrates oral
structures at different levels, depending on
varying anatomical densities, before striking
the film or sensor. Teeth appear lighter
because less radiation penetrates them to
reach the film. Dental caries, infections and
other changes in the bone density, and the
periodontal ligament, appear darker because
X-rays readily penetrate these less dense
structures. Dental restorations (fillings,
crowns) may appear lighter or darker,
depending on the density of the material
21. Panoramic xray
Panoramic films have many
positive elements and are
widely used. They can
reveal both jaws on the
same radiographic film
Also for ( lesions or teeth)
and provide a screening
tool for the maxillary
sinus and orbit.
24. Dentistry definition
Dentistry is the branch of medicine that is
involved in the study, diagnosis, prevention,
and treatment of diseases, disorders and
conditions of the oral cavity, commonly in the
dentition but also the oral mucosa, and of
adjacent and related structures and tissues,
particularly in the maxillofacial (jaw and facial)
area.
45. Reamer
Classical hand root canal reamers are long, tapered,
stainless steel instruments made from rectangular,
triangular, or rhomboidal cross-sectional wires.
More tapered rotary reamers made of nickel-titanium
have essentially replaced the stainless steel hand
reamer
46. • Finger instrument
• Colour coded by size.
The 6 colours used most often are: size 15 (white); 20 (yellow); 25
(red); 30 (blue); 35 (green); 40 (black). Also available in size 6 (pink),
8 (grey) and 10 (purple)
• Operator gradually increases the size of the file to smooth, shape
and enlarge canal
• The larger the number of the file, the larger the diameter of the
working end
• Disposed of in the sharps’ container(safety box)
Endodontic K files
55. Transmission occurs when
droplets containing microbes
from the infected person are
spread a short distance
through the air and deposited on
the host's body
DROPLET TRANSMISSION
56. Droplet generated by sneezing
Coughing or respiratory tract
procedures
like Broncoscopy or suction process
DROPLET TRANSMISSION
57. -Anyone whose resistance to disease
decreases
-Reasons for lowered resistance: age,
existing illnesses, fatigue and stress
-The elderly have weaker immune systems
and a lower resistance to pathogens
WHO IS AT RISK??
