Instrument Care and Sharpening

These flashcards cover key concepts related to instrument care and sharpening, necessary for effective periodontal practice.

Instrument Sharpening

The technique of refining the cutting edge of instruments to enhance their effectiveness in periodontal debridement.

Sharp Instruments

Instruments with a fine cutting edge that efficiently remove deposits during periodontal care.

Dull Instruments

Instruments with worn cutting edges that slide over deposits and may burnish them instead of cutting.

Visual Detection of Sharpness

Evaluation method where a sharp cutting edge does not reflect light, while a dull edge appears rounded and reflects light.

Tactile Evaluation of Sharpness

Assessment by feeling whether a sharp edge grabs the surface of a test stick, unlike a dull edge which slides.

Internal Angle

The angle formed between the face and lateral surface of instruments, ideally between 70-80 degrees.

Goals of Sharpening

To achieve a sharp edge, preserve the instrument design, and conserve the blade.

Perio Retriever

A double-ended, highly magnetized instrument designed for retrieving broken instrument tips from periodontal pockets.

Managing a Broken Working-End

Procedure to follow when a tip breaks, including remaining calm, informing the patient, and attempting retrieval.

Sharpening Technique Steps

Specific steps for sharpening instruments including lubricating the stone and maintaining the correct angle during sharpening.
