Resumo
The endodontic millimetered ruler is necessary to transfer working length to the
endodontic instrument. It must be standardized and accurate to avoid mistakes in interpretation
or measurement which may compromise the success of endodontic therapy. The purpose of this
study was thus to evaluate the standardization and accuracy of four different brands of millimetered
rulers used for endodontic odontometry. Eighty rulers were selected and included in four groups of
twenty each, according to brand: 1. Malleifer; 2. Jon; 3. no brand name; and 4. Imagem. They were
measured with a profile projector. Three cycles were carried out for each position with reference
points from 15 to 25 mm at a temperature of 19.9 °C. as measured by a thermohygrometer. After
statistical analysis using Friedman and linear regression tests, it was concluded that there was no
standardization among the four brands of endodontic rulers tested. All of the endodontic rulers,
whatever the brand, were imprecise in their measurements. Of the four groups, the no-brand rulers
were the most accurate, followed by Imagem, Jon and Malleifer.
