Tooth chronology and dimensions

 Here is sequence of development and eruption of every tooth in mouth and their dimensions also explained 

Complete Morphology Of Permanent Maxillary lateral incisors

Lateral Incisor

 Maxillary lateral inisors are two in numbers and next to central incisors,these are smaller than central incisors. Maxillary lateral incisor shows greater variations  in morhpology

Labial view

It looks like trapezoid in shape labially

Lingual view

Trapezoid in appearance 

Mesial Aspect 

Proximal aspect of permanant maxillary lateral incisor is triangular or wedge shaped.

        Labial out line is less convex than that of  central incisor.

        Lingual out line is like central incisor convex  gingivally with crest of curvature at cingulum,concave in middle (lingual fossa) slightly convex at incisal edge.

Distal Aspect

Tooth morphology of maxillary central incisor

Morphology describes the shape and form of teeth.

There are two sets of teeth in human beings

1: deciduous teeth(milk teeth)

2:permanent (adualt teeth)

 According to shape and functions 4 types of teeth present in mouth

1:incisors 

2:canines 

3:premolars

4:molars 

Teeth are arranged in two arches,upper and lower.

Upper arch named Maxillary arch 

Lower arch  named mandibular  arch 

Each  arch holds 16 teeth out of 32 teeth 

Each arch  is divided into two  Quardrants by midline plan

 Incisors  

      Morphology  of central incisors

          These are towards midline and only teeth having mesial to mesial contact of two central incisors, all other teeth have contact points with mesial of one tooth and distal side of adjascent tooth .

From facial /lingual view crown  is trapazoid and from proximal view it lookslike a Wedge.mosioincisol angle is more square and disto incisol angle is round

Anatomical terminology

Terminology
              Is a general word for group of spacilized words relating to a particular field. Or
        It is a system of terms relating to a particular subject.
 Anatomical terminology
               It is form of a scientific terminology used by anatomist,doctors and zoologist.
It is related to anatomical structures of human and animal bodies.

•      Terms usually used are

  1:Anatomical position

          - body erect
           - head,eyes,toes directed forward
            - limbs at side of body
             - palms directed
               forward
2:prone position
                When the body is lying in anatomical position with face downward
3:supine position
                  When body lying with face up in anatomical position
4: Median plan
                    Vertical plane passing through center of body dividing it into 2 equal halves right and left
5: sagittal plane
                       Vertical plane a parallel to median plane also called paramedian plane
6: coronal plane
                          vertical plane seperates the body into anterior and posterior parts
7: horizontal plane
                         Parallel to floor,perpendicular to coronal and median plane ,separate the body into superior and inferior parts
8: anterior/ventral
                           closer to anterior surface of body
9: posterior/dorsal
                             closer to posterior surface of  body
10: superior/ cranial
               Closer to head
11: inferior/ caudal
                Closer to feet
12:superficial
                  Closer to surface of body
13: deep
             Away from surface
14: proximal
               Closer to root of limbs
15: distal
               Furaway from root of limbs
16: external
                Out side of a hollow structure
17: internal
                 Inside of a hollow structure
18: medial
                   Close to midline
19: lateral
                  Away from midline
