Dental 5/7 Root Canal Plugger

The Dental 5/7 Root Canal Plugger is a double-ended endodontic instrument constructed from surgical-grade stainless steel, carrying two flat, blunted working ends — 0.50mm diameter on one end and 0.75mm on the other, each measured 1mm from the tip. Both ends share a uniform 21mm active length with depth markings at 5mm intervals along the shank, allowing the clinician to monitor penetration depth during vertical condensation without removing the instrument. The shank transitions smoothly from the central handle into each working end through a gentle curve, keeping the flat tip parallel to the canal axis during apical pressure strokes. The silver satin-finish knurled handle provides a controlled pen grasp throughout active compaction.

The Endo Plugger – #5/7 – 21mm – Double Ended occupies the mid-range position within the standard plugger series — larger than the 1/3 figure (0.40/0.45mm) but narrower than the Machtou 3/4 (0.80/1.10mm). This positions the 5/7 as the instrument of choice for moderate canal diameters where smaller pluggers provide insufficient condensation face area and larger ones cannot descend past the coronal third. The two differing tip widths address separate canal zones on a single instrument, eliminating instrument switching mid-sequence.

Endodontists use the Dental 5/7 Root Canal Plugger during warm vertical condensation of gutta-percha in moderately sized canals. The 0.50mm end is pre-fitted to the middle-to-apical third and used to compact thermoplasticized material immediately after down-packing. The 0.75mm end then condenses each backfilled increment at the coronal level until the canal is fully obturated.

The 5/7 Root Canal Plugger is a dependable mid-range staple on any obturation tray. Leader Surgical produces this plugger to consistent tip diameter tolerances, verified stainless steel composition, and sterilization-safe finishing standards.

What is a 5/7 21mm Endo Plugger?
It is a double-ended hand instrument used in endodontics to vertically condense (compact) filling materials like gutta-percha into a prepared root canal.
