Introduction to
dentistry

2. ➢ Dentistry:
Is a healing art and science that is concerned
with the teeth, oral cavity, and associated
structures.
➢ Dentist:
One whose profession is to treat diseases and
injuries of the teeth and oral cavity and to construct
and insert restorations of and for the teeth, jaws,
and mouth.

4. HISTORY OF DENTISTRY

5. THE EARLIEST HISTORY OF TREATING TOOTH RELATED
PROBLEMS GOES ALL THE WAY BACK TO 7000 BC, THE FIRST
METHOD OF TREATMENT WAS BOW DRILLS, WHICH WERE
ANCIENT PRIMITIVE TOOLS USED FOR WOOD WORKING AND
TREATING TOOTH PROBLEMS.
Moving forward into 5000 BC, the Sumerians blamed tooth
worms as the cause of any dental issues, with the worms
boring little holes in your teeth and hiding out inside.
The idea that a worm traveled through your mouth
and was the cause of dental pain lasted until it was
proven false in the 1700s

6. IN ANCIENT GREECE, HIPPOCRATES AND ARISTOTLE
WROTE ABOUT TREATING DECAYED TEETH AS
WELL AS HAVING TEETH EXTRACTED TO KEEP
MOUTH PAIN AWAY.
Interestingly enough, the professionals who were doing
these extractions during the middle ages were not medical
authorities. These partially trainers began using a “Dental
Pelican” in the 14th century and then a “Dental Key” to
extract teeth from their patients’ mouths.

7. The man behind the science was 17th century French
Physician, Pierre Fauchard. He is called “The Father of
Modern Dentistry”, and he was the brains behind many of
the procedures still used in today’s society. For instance,
he was the man behind the thought process for dental
fillings, and he also helped to explain that acids from sugar
are a major source of tooth decay.
From here, the rest is history. In 1840, the first dental
college was opened, called the Baltimore College of Dental
Surgery. This led to more government oversight, and
eventually regulation through the American Dental
Association (ADA).

8. IN 1873, COLGATE MASS-PRODUCED THE FIRST
TOOTHPASTE IN A JAR, AND, JUST A FEW
YEARS LATER, IN 1885 THE FIRST TOOTH
BRUSH WAS MASS PRODUCED IN AMERICA.
THE FIRST REAL ELECTRIC TOOTHBRUSH WAS
PRODUCED IN 1939, BUT IT WAS DEVELOPED
IN SWITZERLAND.

Geriatric dentistry is the delivery of dental care to older adults involving diagnosis, prevention, management and treatment of problems associated
with age

18. ➢ Teeth are more than projections in the mouth that
allow you to grind the food and prepare it for the
initial phase of digestive process.
➢ Teeth are one of the most important elements of
the masticatory system.
➢ Man supplied through his life by two sets of
teeth, a deciduous or primary set, and followed
by a permanent set.

19. 1. Mastication:
It is the most important function of the teeth.
The teeth are designed to perform this function.
2. Appearance:
Well clean teeth with proper alignment give
nice appearance to the face and also support the
facial expressions.

22. 3. Speech:
The teeth are important for clear
pronunciation and for production of sound.
4. Growth of jaws:
The teeth play a role in the growth of the jaw
in some periods.

PRIMARY DENTITION.
MIXED DENTITION.
•
•
• Permanent dentition.

24. ➢ Primary dentition (deciduous dentition, first
dentition): The number of primary teeth present in
the child is usually 20 if none are congenitally
missing or lost as a result of disease.
PRIMARYTEETH

25. ➢ The eruption of primary teeth is expected to begin at
6 months of age.
➢ Usually at age 2 to 2.5 years or thereabout, the
primary dentition is completed.
➢ However, the time of eruption of both the primary
and permanent teeth varies greatly. Variations of six
months either side of the usual eruption dates can
be considered normal for a given child.

27. Usually exists in a person's oral cavity from
approximately 6 to 12 years of age. This mixed
dentition is a combination of primary and
permanent dentition. Mixed dentition occurs as
the permanent teeth begin to erupt within the oral
cavity, while some of the primary teeth are still
present.
MIXED DENTITION

28. ➢ Permanent dentition (secondary dentition): 32
teeth of adulthood that either replace or are added to
the complement of deciduous teeth.
➢ The eruption of permanent teeth is expected to
begin at 6 years of age.
➢ Usually at age 17 to 21 years, the permanent
dentition is completed.
PERMANENT DENTITION

29. ➢ 20 deciduous teeth
Two arches
called the
DENTALARCHES
➢ 32 permanent teeth

30. ➢ one upper and one lower, each arch contains half
the number of the teeth (10 deciduous then later
16 permanent teeth).
➢ The upper jaw is called MAXILLA upper
or maxillary teeth.
➢ The lower jaw is called the MANDIBLE
lower or the mandibular teeth

31. Maxilla
Mandible

33. ➢ THE PERMANENT TEETH ARE EQUALLY ARRANGED
OR GROUPED INTO FOUR QUADRANTS:
1. Upper Right Quadrant or, Maxillary Right Quadrant.
2. Upper Left Quadrant or, Maxillary Left
Quadrant.
3. Lower Right Quadrant or, Mandibular
Right Quadrant.
4. Lower Left Quadrant or, Mandibular Left
Quadrant.
