The present disclosure generally relates to periodontal instruments, and more particularly to periodontal instruments such as scalers and planers used in debridement of root surfaces of a tooth.
Conventional periodontal therapy, also known as non-surgical periodontal therapy, is the most common and conservative form of treatment for periodontal (gum) disease. An important objective of such therapy is to remove or eliminate the etiologic agents that cause inflammation, dental plaque and its products, and calculus, thus helping to establish a periontium that is free of disease. Such therapy may include the use of both scaling and planing procedures to accomplish debridement of the root surface of a given tooth below the gumline.
Scaling is a somewhat coarse procedure by which most of the overall volume of deposits on the root surface below the gumline is removed. Such deposits may include plaque, tartar, cementum, and dentin that is rough or permeated by calculus. When performing scaling procedures below the gumline, clinicians typically use rather heavy gage periodontal instruments equipped with blunt or rounded ends (to protect the soft tissue of the gums) and strong, often rather rugged blades featuring sharp cutting edges in order to break up, dig out, and/or scrape away such deposits in bulk. By comparison, root planing is a relatively fine procedure by which the smaller part of the overall volume of deposits typically left behind on the root surface after the initial scaling procedure is complete is removed. When performing root planing, clinicians typically use somewhat lighter gage periodontal instruments, such as thin curettes, equipped with relatively fine, often razor-like blades featuring very sharp cutting edges to shave (or ‘plane’) away the remaining deposits down to the bare surface of the root, or to smooth the root surfaces by removing any infected tooth structure. Root planing performed after scaling can result in the gum tissue more firmly reattaching to the root surface that are clean and smooth, thereby reducing the likelihood of tooth loss and sensitivity problems. The root planing procedure also makes it more difficult for plaque to accumulate along the surface of the root in the days and weeks after the root surface debridement treatment is complete. As such, clinicians who take the extra time to accomplish root planing immediately after scaling can bring about quicker healing, and more effectively facilitate subsequent re-attachment of the gum tissue to the root surface, than clinicians who perform periodontal therapies in which scaling alone is used.
In order to perform conventional periodontal therapy, clinicians have at their disposal a wide variety of instruments, including ultrasonic tools, as well as manual or hand instruments. Before the advent of ultrasonic scaling, moderate to advanced gum disease was typically treated only by means of surgery. With the current broad availability of ultrasonic scaling, however, most calculus deposits appearing on root surfaces can be removed without surgery. The setup for ultrasonic scaling typically includes a hand piece with a small scaling tip. Used in combination with a water flow, the soft or low amplitude ultrasonic vibration transmitted by the hand piece to the root surface via the scaling tip can quickly and effectively remove most moderate to large-scale calculus deposits.
Whether an ultrasonic scaling hand piece is used for root surface debridement, or traditional manual instruments are used, dental and periodontal clinicians typically place a high value on speed and efficiency. The clinician may prefer or be required to use many different debridement instruments featuring differently configured respective working tips due to differences in anatomical geometry. Such differences may arise, for example, based on whether the root surface being scaled or planed is that of an incisor, a canine, a premolar, or a molar. Such differences may also arise based on whether the root surface being scaled or planed is one or another root surface of the same tooth. Time spent deciding which periodontal instrument to use next, and on actually switching from instrument to instrument, or from working tip to working tip (e.g., during ultrasonic scaling), can add up during a given procedure, lengthening the time for treatment or causing delays which patients and clinicians would prefer to avoid if possible. Accordingly, a current need exists for innovative periodontal tools, instruments, and root surface debridement kits that provide the clinician with greater utility and ease of use.
Accordingly, periodontal instruments, periodontal tools, working tips for periodontal instruments, and periodontal treatment kits for root surface debridement, as well as tooth maps and clinician gowns are disclosed that provide the clinician with greater utility and ease of use.

Scaling and root planing is the most common and conservative form of treatment for periodontal (gum) disease. The objective of scaling and root planing, otherwise known as conventional periodontal therapy or non-surgical periodontal therapy, is to remove or eliminate the etiologic agents which cause inflammation: dental plaque, its products and calculus, thus helping to establish a periodontum that is free of disease. In order to perform this procedure, clinicians typically use a combination of ultrasonic scalers and hand instruments. This disclosure describes, for example, a dual faceted dental surgical instrument that combines scaling and planing into one handy periodontal instrument. This instrument has much utility in the dental arena as it combines multiple instruments, featuring a modified surface for greater utility and ease of use for the clinician.
The following discussion includes a description of particular examples of periodontal instruments, periodontal tools, working tips for periodontal instruments, tooth maps, and periodontal treatment kits in accordance with the principles of the present disclosure. Alternate embodiments are also disclosed.
