| Dental Anatomy |
Analyze the function of the tooth when biting each other and where the
other missing teeth in the chewing surfaces. Dental normal fertilization before
came out of the womb beginning. Dental anatomy as Taxonomy Scent (Taxonomy from
Greek Taxi = managing nomos = law) is classified as science. Regarding the name
of the teeth along with the structures that exist. Primary teeth are generally
28 to 32, with teeth Mars (Wisdom teeth) can grow and not grow. Primary teeth
found on the Upper Jaw teeth 10 and Lower Jaw 10. The permanent teeth in the
Upper Jaw (maxillary) with 16 teeth and Lower jaw (mandible) with 16 teeth.
Teeth and can grow more than 32.
Teeth grow very familiar shape eating it starts from the embryonic cell, Grower
up and grow in the mouth, although it has different characteristics. Baby teeth
begin from 6 to 8 weeks in the womb, and it is not likely at this stage, it
will not have any teeth in the mouth when the baby's born out of the womb.
The first major organs of developing teeth Branchial arch.
Her twig’s "Epithelial Root Sheath growth of epithelial sac of the root.
Dental papilla cell evolves into an Odontoblast the shape of Dentin forming
cells. The title of the papilla and Inner Enamel Epithelium also determine the
shape Crown teeth.
Dental papilla cells in up to three substances are Cement oblast, Osteoblast,
and Fibroblast.
- Cement oblast creator Cementum
- Osteoblasts form the alveolar bone
- Fibroblast periodontal ligament
that attaches the tooth to the alveolar bone through Cementum.
The teeth were divided into the following phases as follows Bud stage, cap, and
Bell Finally maturation. These stages it very interrelated.
II- Identification determining identities
a- Nomenclature
Teeth were put into position Arch stage. Teeth are divided into 2 phases
Baby teeth and permanent teeth. For Succedaneums dental referring to those who
grow (Incisor, Canine, and premolar Dent permanent) and means that the
maxillary upper Jaw Mandible referred Lower jaw.
Teeth were divided into 4 groups, Incisor, canine, premolar, and molar. Premolar
teeth while Incisor is divided into 2 lateral and central Premolar First and
Second premolar Molar divided into 1, 2 and 3.
b- Numbering systems
Numbering systems are very much in determining the dental system to call,
but the system which uses 3 simple background
- FDI (World dental federation notation)
- Universal Numbering System
- Palmer notation method
The FDI system used in all the world the universal numbering system used
in the United States.
In 1891 he Victor Hade rap Dane mark created using the plus (+) and (-) plus
the Upper Jaw and Lower jaw.
For example, +1 -> +5 for the teeth on the right
1+ -> 5+ for the teeth on the left
III- Anatomic Landmarks anatomical location
Crown is part of the teeth were used in two parts
2. Clinical Crown means is part of visible teeth in your mouth when speaking.
Crown composed of Dentin-pulp and Chamber. Before coming phase eruption tooth,
Crown covered by bone, but later Crown was recovering from bone, which we see
as an anatomically normal and Clinically Healthy mouth.
3- Anatomic root
Anatomic root is seen under CEJ armored sheath around the root Cementum
Clinical we cannot see directly in the mouth. Dentin is also an organic part in
creating the Root of Tooth combination with Pulp Canal. The root of the tooth
can be from 1 up to (eg: Incisor, Canine, Premolar usually have 1 or Molar or 2
or 3 ...).
Generally, teeth, jaw, the support structure to combine with Periodontium who
is associated or teeth to the bone.
1- Surface
Surface say that means the surface or parts or regions. Area near Cheek
or Lip is called Facial any surface and near the tongue is called Lingual. For
Facial Surface divided into 2 parts
1. A section in the back and near the cheek called buccal Surface
2. The section near lip and called Labial Surface
The Lingual Surface also be divided into 2 parts
1. The parts that remain in the tongue called Lingual
2. The parts that remain in the back of the tongue Hard Palate called Palatal
Surface
Surface bites, chew food assistance is called Occlusal Surface teeth
called Incisal surface.
Surface near the Junction of the Crown and root called cervical surface
Surface near the end or be called Apical. Mesial and Distal be called in
the same sense Mesial means the nearest surface (Mesial surface) Surface of the
adjacent teeth versus Surface Line median and most distant Distal surface.
2- Cups
Cusp is responsible or bumps that grow on the Occlusal Surface of
posterior teeth and canine. It's part of the chewing surfaces of teeth as
follows
- Canine Cusped 1,
- Maxillary Premolar cusped 2 (1 on the buccal inside Lingual 1)
- Mandible first premolar, cusped 2 (1 on the buccal inside Lingual 1)
- Mandible second premolar, cusped 3 (1 inside buccal 2 at the Lingual)
- Maxillary Molar have cusped 4 (2 on the buccal 2 at the Lingual can have
another small cusped Lingual mesial called Carrabelle cusped)
- Mandible molar Cusped 4 and 5 (2 inside buccal 2 at the Lingual).
3- Cingulum
Cingulum is a brand which places covered enclosed Line Mesiodistal shaped
Encircle and still Lingual Surface, where 1/3 of Cervical of incisor. Generally
U-shaped appearance on the Lingual lob that we can see clearly that it is
growing well. The Cingulum mandibular incisor is shallow less clear to us that
the lack of growth. The canine Cingulum very precise shape and shiny teeth than
others.
4- Ridge
Ridge is a flat line that runs on the teeth
and was named to the place where it is located.
a- buccal ridge line running on the surface Crevice Occlusal the center of the
Buccal Premolar.
B-Lingual Ridge: A line running from Cingulum towards the top Cusped part
Lingual Surface of canine. Cervical ridges run straight on the sides
Mesiodistal 1/3 of Cervical Buccal surface of crown
c- Cusped Ridge: a ridge that divides the top of Cusped (Radiate).
All teeth on Marginal ridge 2 is Mesial and Distal his ridge on the edge of the
Mesial and Distal Lingual tooth surface while Marginal ridge on the corner
Mesial and Distal occlusion surface.
D-Triangular Ridge: Ridge features a triangle from the top Cusped Premolar and
Molar referring to Central Groove
E- Transverse Ridge: Ridge combination of Triangular ridges of a variety of
teeth. For example, the combination of the buccal and lingual Triangular ridges
into Transverse Ridge.
f- Oblige Ridge: There was still occlusal surface of the maxillary Molar caused
by combining distal cusp ridge of Mesiolingual and Triangular Ridge
Distobuccally cusp. Usually Oblige Ridge on the border of the central fossa.
5 -Development Groove
Teeth that show us that growing up a notch shallow groove on Mandibular
central and lacteal incisor. The canine evolution, it has deep scars groove and
makes us realize that there Groove good and very strong growth with the
jawbone.
6- Embrasures
Embrasures gap is shaped like a triangle, which is located between the
proximal surfaces of teeth against each other. Corner of Embrasures due Match
Interdental papillary gingiva, the adjacent teeth together with a contact point
where the teeth touch each other.
The cervical embrasures usually filled with Interdental papillary gingiva. When
the degradation or loss of gums and large Embrasures called Black angle or
Angular is NIGRA
Embrasures 3 functional parts
1. The spill way a hole to pass
2. For preventing food affects the gums and dental cleaning Mechanic 1
3. To help prevent and treat periodontal injuries after clashes
7- MA melon
MA melon is still on the face of tiny bumps shaped like teeth of 3 or 4
lobed. When the diameter of reprisals lamps or bite......... MA melon will wear
away tooth, especially for the elderly. MA melon clearly saw when teeth have
grown out of the oral cavity.
Note: For adults, if there is room MA melon, let us know that he had a problem
Malocclusion.
IV- Distinguishing characteristic of teeth characterizing teeth
A- Incisor: 8 teeth for Maxillary 4 and Mandible 4
It contains functions for food and non-cusped but it has a surface area on the
teeth for a meal called incisal ridge or incisal edge
1- Maxillary central incisor: the crown of it, we see clearly Crown square
shaped and melon it faded away when older people (from war).
2- Maxillary lateral incisor: It is located adjacent distal surface of
maxillary central incisor and the mesial surface of maxillary canine.
4- Mandibular lateral incisor: It is located next to the corner and distal of
mandibular central incisor and with corner Mesial of mandibular canine.
B canine: It all amounts to 4 molar teeth on the lower jaw 2 and 2 also can
call it a corner stone, also because it is near and cusped 1
2- Mandibular canine: It has the same shape and maxillary canine except it
grows on the lower jaw.
C- Premolar: it amounted to 8 teeth, jaw on 4 and jaw under 4 and it does not
exist in phase it grows in whither broken missing and located next corner
distal of canine and the other adjacent corner Mesial of first molar.
1 Maxillary first premolar: it is positioned between the distal of maxillary
canine and corner Mesial of maxillary second premolar for functional bites and
food and it 2cuspids at the buccal sharp stronger. The Crown bent at a third of
the cervical refers to the root. Or 2 and sometimes creek
2- Maxillary second premolar: It is situated between the upper teeth distal
maxillary first premolar corner and the other at the Mesial of first molar and
function as first Molar. It has 2 cusp on the buccal shaped large and sharp
Lingual small fir and functional chewing.
3- Mandibular first premolar: It is situated between the mandibular
canine teeth next corner
and distal side’s mesial mandibular second premolar. It functions like a canine
mandibular and 2 cusp cusped and sharp on the buccal or a number.
4- Mandibular second premolar: It is situated between the first premolar
mandibular teeth on the distal side and the side mesial mandibular first molar
and function as Molar cusped 3 but cusp larger and sharper on the buccal.
D Molar: It is located next after Premolar functions for grinding and chewing
food thoroughly Cusped than 4 and up, depending on the mouth of the primary and
permanent molar differ dramatically. They called Molar who later called the
Wisdom teeth (Molar from the Latin word meaning mill).
1- Maxillary first molar
It is located between Second premolar teeth second Molar and it Cusped 4 2 2 on
the buccal and palatal root and 3.
2- Maxillary second molar
it is situated between the teeth, maxillary first Molar Distal Third Molar
mesial. Molar tooth permanent and primary teeth difference Third Molar behind
it. And it has Cusped 3, 4 and root.
3- Maxillary third molar
It is located to the Dismal’s second mandible and Primary teeth do not have
teeth, it contains Cusped 4, is at the Buccal 2 and above Lingual 2, it has the
roots of 3 and the shape change much, they can call it Wisdom teeth.
4- Mandibular first molar
It is situated between the teeth Mandibular second premolar side Distal and
second molar side Mesial it functions for milling chewing food mashing and
there Cusp 5 2 at inside Buccal 2 other on Lingual and 1 other on the Distal
and it Oppose and First molar of Maxillary. 2, or the Mesial and Distal
5- Mandibular second molar
It is situated between the Mandibular first molar teeth and Distal Third Molar
Mesial side and the normal tooth Cusp 4 2 2 on the buccal inside Lingual and it
has 2 or above Mesial and Distal
6- Mandibular third molar
It's next to side Distal and second molar of mandible for primary teeth do not
have teeth, and dental forms and shape vary greatly depending on individual
locations.
V- The root canal
is the study of the anatomy of the eye socket or teeth? Nature in the
central part of the tooth, there is a hollow hole, located in the roots, which
is a place for storage to him (Block) pulp (a hole in your teeth that it has a
hollow hole, a parent, including small holes which are separated from Pulp to
other places on the Root.
1- Tooth structure
In the center of the tooth (the cob, etc. teeth), it was the region Hole,
which is a storage location soft tissue Otherwise (connective tissue), such as
Nerve, blood vessel and connective tissue loophole are broad at the head, teeth
called Pulp chamber. Hole run from wells root-like pencil wells 1. Pulp
received husbandry and supply through the blood vessels and small nerve that
runs through sending signals to the brain. When dental problems and pain it can
recover if treated pulp canal of the root properly.
2- Pulp
Space in the hole or gap teeth loaded with that nerves and blood vessels.
Connective tissue, which is very loosely and talents is a pulp Dental, a
subsidiary and other tissues, such as dentin. Dental pulp and who are
contributing to creating a local dental germination period of 1 to 2 years
after germination present in the oral cavity. Moreover
the teeth also provide support for raising the pulp as well, making teeth there
is a strong, tough and not easily broken or brittle fracture when chewing food.
The pulp had any function as to what is too hot or cold. Root canal is a word
very simple for use in inequality yuan dental portion endodontic therapy is
treatment cut piercings and the remove the organ that was in the canal pulp out
and then cleaning washing antiseptic and take drugs coming off touches to full
chignon hole holes or white.
3- Root canal anatomy
in the anatomy of the root canal is the pulp chamber and root canal. Both
organs are in Dental pulp and it has separated longer a small tree called
accessory canal that was visible near the apex but also along the body or
teeth. root canal, it amounts to more or less depending on the number of roots
of the teeth more or less the same Example if dental or 1, the root canal also
has 1 well is their team, if available, or 4, it will also have a root canal 4
as well. For teeth that are more or that bringing the issue failed to treat
very well. Example Before treatment, we know that first maxillary molar with or
3, and also has roots 3, but sometimes the roots side lingual, it can have
roots split into 2 more, so that we're wrong, that's why treatment Levi met
defeat.
