yellow = cementum pink = PDL green = bony socket blue = junctional epithelium/sulcular epithelium
HERS
What do the red and blue arrows represent
PDL development
red = during eruption blue = after eruption
What do the pink and green represent
pink = cellular cementum green = acellular cementum
fiber fringe

predentin
mineralized dentin
non-mineralized dentin
advancing root edge
HERS
mineralized cementum
mineralized dentin
fiber fringe

cementoblasts
mineralized dentin
What are these strucutres from left to right
cementoblast
collagen fibers/fiber fringe at the ends
predentin
What is the green arrow
cementoblast
What is taking place in this image
mineralization of the fiber fringe (at descrete foci denoted by the arrows)
What is taking place in this image
total mineralization of the fiber fringe = cementum
What is taking place at the red line
mineralization front
Which one of these arrows is pointing to the primary cementum and secondary cementum
second arrow = primary
last arrow = secondary
What is the main purpose of this cementum
attachment
What is this image depicting
that cementum width varies
What do the blue and purple arrows represent
blue = cellular intrinsic fiber cementum
purple = mixed fiber cementum
What are these tissues
outside = acellular cementum inside = dentin
What are these tissues (from left to right)
left most = acellular cementum
Tome’s granular layer
right = dentin
What are these tissues
cellular cementum
dentin

What is this
cementoblasts
cementoid
What are these
lines = growth lines

hypercementosis
What do the black circle and arrow represent
the extent of the periodontal ligament
What is the arrow pointing to
cementoblasts
What are the arrows point to from top to bottom
osteoblasts
osteoclasts
cementoblasts
blue arrow = osteoclasts
red arrow = osteoblasts
epithelial rests of Mallesez
epitheial rest of Mallesez
What is this image showing

Where are these vessels penetrating
foramen in the alveolar socket
white i = cellular cementum
arrows = PDL
black i = alveolar bone
yellow stars = vascular bundles
black arrows = nerve fiber bundles
alveolar process
What are the differnt types of bone
C = cortical T = trabecular
What are the differnt types of bone
yellow arrow = bundle bone
C = cortical
T = trabecular
yellow arrows = bundle bone
orange i = trabecular bone
blue i = cortical bone
What is the radioopaque like surrounding the bone
lamina dura
What are these images depicting
the cribiform plate-likeness of the alveolar process
What does the black i represent
Sharpey’s fibers
