Objectives of Obturation

Create a complete seal of the entire rootcanal system by eliminating all avenuesof leakage from the oral cavity or theperiradicular tissues into the root canalsystem.

To seal within the system any irritantsthat cannot be fully removed duringcanal cleaning and shaping procedures.

Completed C&S

The canal systemshould be properlytapered in a continuous

funnel shape allowingdebridement, irrigationand obturation.

Completed C&S

Note your FWL.*FWL is 1mm short of

patency length.

Example: FWL=23mm

Spreader Fit

To check satisfactory apical cleaning andshaping before obturation.

To see if there is enough room forcompaction with the selected fingerspreader. (size: medium fine MF)

Set rubber stop 1-2mm short of FWL.

Spreader fit

Fit within 1-2mmof FWL.

If not, moreshaping is requiredbecause apical sizeand taper isinadequate.

MC is short

Reinsert MAF file. Sometimes, dentin

filings prevents itfrom seating toFWL.

Reshape

Check to see ifMAF goes to FWL.

Go through handfiling procedure.

Sometimes,repeating C&S withrotaries is necessary.

Refit MC

After filing with theMAF to FWL, theselected Master

Cone should fit toproper FWL also.

Master Cone Fit

The MC should have a definite apicalresistance when MC is placed to FWL.

The MC should exhibit tugback orresistance to removal.
