R&S manual K-FILES files - 25mm

The R&S K-Files 25mm are precision stainless steel hand instruments designed for root canal catheterisation — the initial exploration, negotiation, and shaping step in endodontic treatment. Manufactured in France by R&S, each 6-file pack lets dentists in Egypt reliably locate, identify, and prepare the canal system before rotary or hand instrumentation continues, using ISO-standard colour-coded stops for fast size recognition chairside.

Clinical Uses

• Initial canal negotiation and patency confirmation before rotary shaping
• Manual filing and canal wall smoothing in narrow or curved canals
• Removal of pulp tissue and dentin debris during cleaning and shaping
• Working length verification with an apex locator or radiograph

Key Features

• ISO diameter colour coding on every file for instant size identification
• Stop colour indicates length: blue = 25mm, red = 21mm
• Square cross-section on sizes 06–10 for rigidity; triangular cross-section on 15–40 for flexibility
• Ergonomic finger-fitted handle for tactile control during filing

Specifications

How to Use

1. Confirm working length with a radiograph or apex locator before starting.
2. Irrigate the canal generously with sodium hypochlorite solution before and between files.
3. Insert the file passively to the previous size's depth, then work with a gentle back-and-forth (watch-winding) motion — never force.
4. Withdraw, wipe, and irrigate between each file to clear debris and re-confirm patency.
5. Progress sequentially through sizes until the canal is shaped to the planned master apical size.

Why Buy From MedSTA

• Genuine R&S stock, not unmarked substitutes common in the Egyptian market
• Fast Cairo-wide and nationwide delivery for busy clinics
• Direct support from a dedicated dental supply team — not a general marketplace

FAQ

What does the 25mm length mean?
It's the total working length of the file from tip to handle stop — R&S marks 25mm files with a blue stop and 21mm files with a red stop, so you can tell them apart at a glance.

Can R&S K-Files be reused after sterilization?
Like most stainless steel hand files, they can be autoclaved and reused for a limited number of cycles, but should be discarded once flutes show any distortion or unwinding.

What's the difference between the square and triangular cross-section sizes?
Sizes 06, 08, and 10 use a square cross-section for extra rigidity in very fine canals, while sizes 15–40 use a triangular cross-section that improves flexibility for larger, more curved canals.

Do I need EDTA or another lubricant with these files?
Yes — using an EDTA gel or solution alongside K-files reduces friction and helps clear the smear layer, especially in calcified or narrow canals.

Pair these files with Gates Glidden drills for coronal flaring, EDTA solution for canal lubrication, Manual H-Files for canal finishing, and Gutta Percha points for obturation once shaping is complete.
