Video summary
Pulpectomy is a dental procedure typically performed on primary teeth that involves removing both the coronal and radicular portions of the pulp, followed by filling the root canal space with an appropriate material. The process concludes by sealing the tooth's crown using restorative materials and placing a stainless steel crown to ensure long-term protection. This treatment becomes necessary when inflammation has spread throughout the entire pulp tissue, which is clinically indicated by dark red or purple hemorrhage oozing from the canal orifice that does not stop easily even after applying wet cotton for several minutes. Patients usually present with symptoms of irreversible pulpitis characterized by spontaneous pain that persists long after stimuli are removed and may experience night pains or increased discomfort during postural changes, such as lying down, due to elevated intrapulpal pressure.
Radiographic examination often reveals periapical changes including interradicular radiolucency and bone loss in the furcation area, confirming the extent of infection beyond just the pulp chamber. Unlike procedures on permanent teeth where biomechanical preparation is prioritized, pulpectomy in primary dentition places greater emphasis on chemical disinfection of both the pulp chamber and root canals. This shift in focus is primarily due to the short course of the root canal space in baby teeth and the presence of numerous accessory canals, particularly within the furcation region, which make thorough cleaning essential for successful healing.
Following a complete chemomechanical preparation of the root canal system, clinicians utilize specific obturating materials designed for primary dentition to fill the cleaned spaces effectively. Commonly used substances include zinc oxide eugenol, calcium hydroxide, iodoform-based pastes like Vitapex or Metapex, and other specialized filling agents such as Endoflas that provide both sealing properties and therapeutic benefits against residual bacteria. The selection of these materials is critical because they must accommodate the unique anatomical challenges of primary teeth while ensuring a sterile environment within the root canal system to prevent reinfection before final restoration.
The most crucial step after completing pulpectomy involves providing a hermetic seal for the coronal portion of the tooth using a stainless steel crown, which acts as an artificial enamel layer to protect the remaining dentin structure from fracture and bacterial leakage. Without this robust sealing mechanism, the treated primary tooth would be highly susceptible to failure due to its thin walls and the high functional forces it endures during chewing. By combining thorough chemical disinfection with appropriate filling materials and a definitive coronal seal via a stainless steel crown, pulpectomy offers a viable option to preserve natural primary teeth until they naturally exfoliate, maintaining proper space for permanent successors while alleviating patient pain and restoring function.

procedure which is usually performed in
a primary tube it involves the removal
of the coronal and the radicular portion
of the pulp followed by the placement of
a suitable material within the radical
space and sealing the coronal portion of
the tooth by using a restorative
material and finally a stainless steel
crown when is it indicated it is usually
indicated when the inflammation has
spread to the coronal as well as the
radical portion of the pulp which is
indicated by a hemorrhage which is dark
red or purple in color which oceans out
of the canal orifice and which is not
easily stopped even after the placement
of a wet cotton for three to five
minutes the patient will give a history
of irreversible palpitus which is the
pain will be spontaneous in nature which
lingers for a longer period of time even
after the removal of the stimuli the
patient may also complain of a night
pain or pain which increases during
postural changes that is when the
patient lies down the pain increases it
is caused due to an increase in the
intra purple pressure
radiographically there will be evidence
of periodicular changes inter radical
radiolucency inter radicular bone loss
Etc
unlike in permanent teeth uh the Prime
in primary tooth palpectomies the chem
the chemical disinfection of the pulp
chamber and the root canals is more
important as compared to that of
biomechanical preparation which is more
important in permanent dentition this is
mainly because of the Torches course of
the root canal space in the primary
indentation and also due to the presence
of a larger number of accessory canals
especially in the furcation region after
a complete chemo mechanical preparation
of the Road Canal space the obturating
materials that are most commonly used
for the obturation are zinc oxide
eugenol calcium hydroxide iodoform
calcium hydroxide base iodoform base
space like vitapex metapex etc endoflas
etc after the pulpectomy is completed it
is very important to provide a hermetic
seal of the coronal Portion by using a
stainless steel crown
I hope the basic concept of pulpectomy
is clear for everyone I will be back
with another video Until then bye bye
thank you
