Hot Tips for Obturation Success

Why allow your dental customers to bring out the heavy artillery to obturate a root canal, when all they need are two compact units from DiaDent?

The purpose of obturating a root canal is to fill the space three-dimensionally to eliminate entryways through which bacteria might gain a foothold. Thanks to DiaDent, sales professionals can offer their customers a bulletproof way to seal root canals that will help ensure treatment success.

Studies indicate that using the warm compaction technique increases the chances that no voids will be left behind in the obturation process. Warming gutta-percha to its thermoplastic state allows it to easily flow where it might not otherwise go. But while countless methods and techniques are available for this procedure, perhaps none is as promising as DiaDent's warm vertical compaction system.

With DiaDent's efficient obturating system, there's no need for the dental operatory to look like a war zone. No more messing around with open flames, ovens and accidents waiting to happen. The system uses two devices — the Dia-Pen and Dia-Gun — to deliver complete obturation. It's neat, tidy, safe and simple. Your clinical customers are sure to appreciate the confidence and convenience this "Dia-duo" provides in allowing them to achieve consistently successful results.

THE MIGHTY PEN

First in the DiaDent lineup is the Dia-Pen, a warm vertical compaction device that delivers reliable and predictable clinical outcomes. After a canal has been cleaned and shaped, a gutta-percha cone is selected for a snug fit and tug back, according to the prepared apical size of the canal (Figure 1). The corresponding Dia-Pen tip, which is available in a range of color-coded sizes, is inserted into the canal to the point that it is 4 to 7 mm short of the working length. The endo stop is set accordingly.

Next, the gutta-percha cone is coated in sealer and placed into the canal. The Dia-Pen is used to quickly cut the cone in the middle, and the remaining material is softened and briefly compressed to approximately 6 to 9 mm from the apex. The Dia-Pen is then deactivated and allowed to cool while the operator continues to push downward. This further compacts the gutta-percha vertically and into lateral and accessory canals. Following this, the device is activated once more and the warmed gutta-percha continues to be pressed to the point of 4 to 7 mm of working length. The material is condensed once more with the use of a hand plugger. Because this area is narrow and often curved, the Dia-Pen is an excellent choice for this job, thanks to its fine needles and compact size — allowing both safety and optimal access and visibility.

THE TRUSTY GUN

The Dia-Pen is followed by the Dia-Gun, which employs a warm backfill technique on top of the material compressed by the Dia-Pen and hand plugger. The Dia-Gun extrudes small amounts of gutta-percha into the yet unfilled portion of the canal (Figure 2). Following each precise extrusion, a hand plugger is used to compact and spread the material laterally, eliminating any voids. The process is repeated incrementally until the canal is completely filled.

The Dia-Gun comes with two types of disposable tips that can be warmed to low, medium or high settings. The tips can be bent to the desired shape and angle using the multi-purpose wrench that's provided. (Bending by hand is not recommended, as this can result in broken tips.) Gutta-percha pellets (included with the Dia-Gun kit) are placed into the loading slot and, once loaded, the gutta-percha is pushed into the heat chamber via the plugger. Temperature on the activated gun can be easily seen on the digital display. The gun's heat chamber swivels 360 degrees to allow safe, easy changes to the tip's direction, providing versatility and convenience when backfilling maxillary teeth.

COOL FEATURES

Both the Dia-Pen and Dia-Gun feature lightweight, compact and cordless designs for freedom of movement around the office — or just around a patient. In fact, at just 65 grams, the Dia-Pen is among the lightest instruments in its class. Both units help ensure effectively and tightly compacted canals, including lateral canals, resulting in an optimum seal.

The Dia-Pen features three temperature settings for its quick-heating tip. Low temperature mode is pre-set for 170º C; the medium setting is 200º C; and the high setting quickly tops out at 220º C, saving treatment time. An easy-to-clean silicone cover fits over the device to protect it from debris. For easy identification, color-coded pen tips — which can be adjusted into six positions — are available in a variety of sizes. The intuitive controls for the Dia-Pen include power- and tip-setting functions, temperature setting and operation mode.

The Dia-Gun is designed to provide reliability and precision while delivering a fast, continuous flow of canal-sealing gutta-percha. Variable temperature settings, including 160º C, 180º C and 200º C, offer superb control of obturation flow. And, thanks to the Quick Heating System, tip temperature can reach 200º C in just 25 seconds.

The ergonomically designed 360-degree Swivel Needle allows improved access, while the thin tip eases narrow canal filling. Other benefits include a lid for the heat chamber that offers protection from dust and dirt; a safety cap that offers protection for both patient and operator; and a silver alloy gun tip that guards against breakage.

TAKE THE HEAT

What busy clinician wouldn't enjoy the advantages of a lightweight, compact, warm obturation system that's easy to use and will help deliver great results? As a bonus, the ergonomic design of each unit reduces hand fatigue, while offering comfort and excellent tactile feedback. Both units are easy to clean with a soft cloth and alcohol prior to autoclaving. A scrubbing brush is included to help remove residual gutta-percha from the Dia-Gun.

With DiaDent's Dia-Pen and Dia-Gun in their armamentariums, your customers will be well prepared to deal with any obturation challenge that comes their way. And that's a hot tip worth sharing.
