DEFINITION .
Obtusa1-ion -
'
to obstruct
'
or to occlude
Obtusa 1-ion is the method used to fill and seal a cleaned and

OBJECTIVE
• Fluid

Fluid

• Bacteria

•
Total obliteration of soot canal

.

7. NEED FOR OBTU RATION
• TREduce coronal leakace and bacterial contamination,
• Seal the
apex
from the
periapical tissue ,
• Entomb the
Detraining
imitates in the canal .

TIMING OF OBTU RATION
Factois
influencing the
timing of obtusa1-ion
depends on :
Patient's
signs
and
symptoms
ii) status of
pulp and
pesciapical tissue.
iii
Degree of
difficulty including procedural excess
iv

,
psychological state.
NOTE : Microbes are
