The main objectiveof pulp therapy in the primary dentition
is to retain every primary tooth as a fully functional
component in the dental arch to allow for proper mastication,
phonation, swallowing, preservation of the space required for
eruption of permanent teeth and prevention of detrimental
psychological effects due to tooth loss.
UNCONTROLLED PULPAL HEMORRHAGE
Indicatedfor any tooth in absence of successor
Any deciduous teeth with severe pulpal necrosis
provided there is no radiographic contraindication
Primary teeth with necrotic pulps and minimum of
root resorption
Primary teeth with an abscess or sinus opening
Traumatized teeth with fracture or caries involving the
pulp irreversibly
INDICATION-CLINICAL
• Young patientwith systemic illness such as
congenital ischemic heart
disease, leukemia
• Children on long term steriods therapy or those
who are immunocompromised.
CONTRA-INDICATION-GENERAL
10.
• Excessive toothmobility and /or reduced bone
support
• A non- restorable tooth
• Underlying dentigerous or follicular cyst
• Communication between the roof of pulp
chamber and the furcation Region
• Insufficient tooth structure to allow isolation by
rubber dam and extracoronal restoration
CONTRA-INDICATION-CLINICAL
11.
-A primary toothwith excessive root resorption
invoving more than
two thirds of the root
-Internal root resorption in the apical 1/3 rd of the
root
- Radicular cyst, dentigerous cyst in association
with primary teeth
- Inter- radicular radiolucency that communicate
with the gingival sulcus
CONTRA-INDICATION-RADIOGRAPHICALLLY
12.
Partial pulpectomy
i
procedure’ inwhich the coronal portion of the radicular
pulp is amputated, leaving vital tissue in the canal that is
assumed to be healthy
• The decision to implement partial pulpectomy in primary
molars is made after removing the coronal pulp and
encountering difficulty with hemorrhage control from the
radicular orifice.
• The canals should not show evidence of necrosis or
suppuration
• It is widely used to refer to an:-
13.
Indication
-Large carious exposure
with
frankinvolvement of
radicular pulp without any periapical changes
-Primary teeth with inflammation extending
beyond
coronal pulp indicated by hemmorrhage from
the amputed radicualar stumps that is dark red, a
slowly oozing and uncontrollable.
-Teeth that exhibit clinical symptoms to heat or cold
and not to percussion
• Studied byLawrence 1966 and later by starky 1973
Indication (Paterson and Curzon in 1992 )
• Indicated where infection , an abscess and chronic sinus exist
• Nonvital primary teeth
• Teeth with necrotic pulp and periapical invovlement
MULTIPLE VISIT PULPECTOMY
THIRD APPOINMENT (OBTURATION)
Appointmentshould be 5-7 days apart
Remove the temporary restoration
Irrigate and dry the canaI
Startobturating
First coat the walls of canal with thin watery mix of cement with the help
of
Reamerand then then use thickmix andfilI the canals using lenturospirals
Keep adding fresh mix till no further cement can be incorporated in
canals Seal the pulp chamber with temporary restoration
Recall after 1 week and if asymptomatic , do final restoration and give SSC.
That endodontic coronalpreparation which enables unobstructed
access to the canal orifice , a straight line access to the apical
foramen, complete authority over the enlarging instrument and to
accommodate the filling technique
ACCESS OPENING for pulpectomy in
primary teeth
24.
Rules
1. Obtaining astraight line access to the apical foramen or to the
Initial
Curvature of canal to aid in
-improvised instrumentation control
- Improved obturation
-decreases the procedural error
2. Conservation of tooth structure:
-to minimize weakening of remaining tooth structure
3. Unroofing the pulp chamber and removal of the pulp horns to aid
in
-locating the root canal orifice
-maximum visibility
-locate canals
30.
Since instrumentation andirrigation with an inert solution
ALONE CANNOT ADEQUATELY REDUCE THE MICROBIAL
POPULATION IN AROOT CANAL SYSTEM:-
Disinfection with irrigants such as one percent sodium
hypochlorite and/or chlorhexidine is an important step in
assuring optimal bacterial decontamination of the canals.
• Non-inflammatory andnon-irritating to the
underlying permanent tooth germ
• Radio-opacity for visualization on radiographs
• Ease of insertion
• Ease of removal
•Should not cause any discoloration of tooth
