Types of endodontic rulers
Endo ring ruler
The endo ring ruler sits on a finger, with a scale up to 3.5 cm. A file is laid against it and its length is read and set without putting the file down or reaching for a ruler on the tray — the endo ring is used for hand and rotary files and for spreaders, pluggers and points.
Flat stainless steel ruler
The 6-inch stainless steel ruler carries inch and centimeter scales on one blade, so a length can be read in either system — a stainless steel mm ruler that stays with the restorative or endodontic set and goes through the same sterilization as the instruments it measures.
How to choose an endodontic ruler
- Chairside file work: the ring keeps the endo ruler on the hand during instrumentation and obturation.
- Tray and laboratory: the flat stainless steel ruler measures longer items, models and laboratory work.
What are endodontic rulers used for?
Measuring files and setting their stops to the working length; checking the length of spreaders, pluggers and points during the procedure; and measuring instruments, materials, models and laboratory work at the chair and on the bench.
