cavity of a female lion. Notice the small blood spot on the
mandibular left 4th Pre-Molar.

Close
up view of a Class III fracture of the middle cusp of this
mandibular left 4th pre-molar. Instrument is a periodontal
pocket probe with 3mm markings.

View
of proper placement of intra-oral radiograph packet, which can
be held in place with an ordinary rubber dental 'bite-block'.

Utilizing
a tapered diamond dental bur to open access into coronal portion
of pulp canal down to fresh, vital, healthy pulp tissue.

It
is normal and very desirable to have copious bleeding from
freshly amputated pulp tissue. If this tissue is healthy, the
bleeding will stop within a few moments, because of the
constriction and clotting of normal healthy blood vessels. This
slow down and clotting is a sign that the exposed pulpal tissue
has been amputated back to healthy tissue, which has the
capacity to heal, and form a secondary dentin bridge.

The
interior of the "cavity preparation" is cleaned with
solutions of hydrogen peroxide and sodium hypochlorite -
injected simultaneously to maximize cleaning effect.

Placing
a layer of Bioglass synthetic, particulate grafting material
into the "cavity preparation", and utilizing a sterile
plastic packing instrument to condense this hemostatic material
gently onto the amputated 'stump' of healthy pulp tissue.

Injecting
a second layer of restorative Calcium Hydroxide material over
the Bioglass to protect it from the disruptive sequence of
restorative materials which follow.
