9/11 Posterior Root Canal Plugger
Double-ended endodontic plugger with large flat tips for controlled gutta-percha compaction in posterior canals.
Key Features:
• Double-ended design with 1.00 mm and 1.15 mm flat blunted tips
• Tip diameters measured 1 mm from tip for standardized sizing
• 21 mm working length on both ends for full canal reach
• 1.00 mm tip for middle-third compaction; 1.15 mm for coronal backfill
• Depth markings at 5 mm intervals for penetration monitoring
• Angled shanks align tips with posterior canal anatomy
• Satin-finish knurled handle for secure, low-fatigue grip
• Surgical-grade stainless steel construction, autoclavable at 134°C
The 9/11 Posterior Root Canal Plugger is a double-ended endodontic instrument built from surgical-grade stainless steel, carrying two flat, blunted working ends — 1.00mm in diameter on one end and 1.15mm on the other, each measured 1mm from the tip. Both ends share a 21mm active length with depth markings at 5mm intervals along the shank for real-time penetration monitoring during the obturation sequence. The slightly angled shank on each end positions the flat tip parallel to the posterior canal axis, maintaining full contact between the condensation face and the gutta-percha mass during apical pressure strokes. The satin silver knurled handle provides a firm pen grasp with low-fatigue balance throughout repeated compaction cycles.
The 9/11 Root Canal Plugger 21mm 1.00mm & 1.15mm DE is the largest standard-format plugger in the ISO series — sized specifically for the wider, straighter canal anatomies found in posterior teeth. Where the 5/7 figure (0.50/0.75mm) addresses moderate canals, the 9/11 targets molars and premolars with broader coronal-to-middle canal diameters. The 1.00mm end handles the middle-third condensation zone while the 1.15mm face manages orifice-level compaction of each backfilled increment.
Endodontists use the 9/11 Posterior Root Canal Plugger during warm vertical condensation in posterior teeth with standard-to-wide canal preparation. After the heated instrument completes down-packing, the clinician introduces the 1.00mm end to compress the first backfilled gutta-percha segment. The 1.15mm end then seats each subsequent increment coronally until the canal is fully obturated at the orifice level.
The Endo Plugger – #9/11 – 21mm delivers confident posterior obturation on every case. Leader Surgical produces this instrument to consistent tip diameter tolerances, verified stainless steel composition, and sterilization-safe finishing.
What do the numbers 9 and 11 represent?
These numbers indicate the diameter of the working ends in hundredths of a millimeter at the tip: 1.00 mm (#9) and 1.15 mm (#11).
