lecture on Anatomy Of Teeth

1. Lecture by: DR.SAIQUA
Reference : Anatomy and Physiology
By Kenneth S. Saladin

2.  Dentition
 16 in mandible and 16 in maxilla
 On each side of midline there are two incisors, one
canine, two premolars and three molars
 Incisors are chisel like cutting teeth
 Canines are pointed act to puncture and shred
 Premolars and molars crushing and grinding

3.  DECIDUOUS 20 ( 6- 30 MONTHS)
 PERMANENT 32 ( 6-25 YEARS)
 WISDM 17-25
 TERMS
 Occlusion
 Occlusal surface
 Cusps: rounded bumps
 Bicuspids : premolar

5.  Teeth is embedded socket called alveolus
 Teeth makes joint with alveolus that joint called gomphosis (
between teeth and bone)
 Periodontal ligament attaches bone and teeth
 Alveolar bone is covered by Gum or also called gingiva
 Gingival Sulcus: space between tooth and gum
 ROOT:
 NECK: point at which crown ,neck and gum meet
 CROWN: Part above the Gum

7.  DENTIN: Living connective tissue(odentocytes),
cells embedded in calcified cell matrix
 Cementum: Living Connective tissue at the root (
cementocytes)
 Enamel : Non cellular secretion released before teeth
erupts
Enemal can not be regenerated
Internally teeth has a PULP CAVITY in the crown and a
narrow root canal in the root
PULP : Mass of Loose Connective Tissue, blood and
Lymphatic vessels and nerves
Apical Foramen: Pore at the root of each tooth
