Henriques PSG, Rua Hilário Magro Jr
The most commonly used procedure for root surface debridement is mechanical scaling and root planing using hand instruments. Periodontal files are used as a part of treatment introduced in subgingivally pockets. The difficult lies in establishing an analogy of this depth measurement to the probe by a PCP 12 and the corresponding input of this file at the same distance. The author’spresent new files, similar to Hirschfeld, have been modified with external marking at 12 mm, allowing the Periodontist this analogy, and facilitating the process.
On the other hand a specific small diameter PH enriques 6 and PH enriques 7 files, to instrument more easily this complex region. Consist of a series of 3 blades and its sharp edges in 270 degrees around the active tip, reaching the root trunk, fornix and neighbor´s surfaces. They are extremely useful especially in Class III involvement and sharpening in the same way as conventional files.
