Since 1989, Discus has been regarded as both the pioneer and global leader in teeth whitening. The Discus flagship product, NiteWhite, was developed by company founders Dr. Bill Dorfman and Robert Hayman, who sold cases of syringes directly to US dentists out of a small Los Angeles office with the aid of a small team of high-energy, enthusiastic sales reps. Over the years, Discus enhanced its whitening portfolio to include a full offering of both chairside (Zoom!, BriteSmile, Dash) and take-home (NiteWhite, DayWhite, Whitespeed) options for dentists and their patients.
Over the next few years, the company expanded beyond whitening to launch a line of impression materials (Splash, Precision) restorative materials (FLASHlite, Matrixx, Cabrio) and oral hygiene products (BreathRx, Fluoridex). The following decade in Discus’ history was defined by bold, sexy marketing campaigns and a direct sales model that fostered close relationships between Discus and its customers. This customer-centric model, coupled with aggressive and daring promotions, positioned Discus as the veritable “gold-standard” of marketing in dentistry.
By 2004, Discus gained a loyal customer base of over 50,000 North American dentists, direct operations in Canada, the UK, Germany, Benelux, France, Spain, Australia, and New Zealand, and a global presence through distributors in over 90 more countries. In an effort to offer global clients more than esthetic solutions, Discus explored entry into an entirely new area to the Company—endodontics. The goal was to develop something unique and effective that would truly make an impact on the endodontic community. The company wanted a system that offered both the dentist and their patients a better and more effective treatment method, and a system that put patient safety first.
In June 2006, both companies were acquired by Discus and the creation of the SMART Endodontics was in full swing. It was now time to ignite the Discus marketing machine, leverage the company’s strong direct-selling model and vast international dealer network to introduce these products to Discus’ broad base of customers.
This philosophy is one that seems to be gaining momentum these days. “At Penn, we teach all of our endo post-docs the importance of treating root canals with biologically acceptable root canal preparations,” explains Dr. Syngcuk Kim, endodontist and Professor and Chair of the Department of Endodontics at the University of Pennsylvania. “Preserving healthy tooth structure and respecting what nature created is fundamental in all our teachings. An instrument that helps accomplish this is a key part of our endodontic armamentarium.”
In terms of safety, the unique features of the LSX instrument are best described by an on-going study at Creighton Dental School, where the faculty has been teaching dental students the LightSpeed technique for roughly 10 years. A study conducted with the previous version of LightSpeed (LS1) showed a remarkably low irretrievable breakage rate of 1.3%. Since Creighton converted from LS1 to LSX in 2005, they continued monitoring instrument breakage. Out of 3,100 canals treated by junior and senior dental students using the LightSpeedLSX with the new safety release feature, the breakage rate dropped from 1.3% to only 0.37%—a reduction of approximately 72%.
While irretrievable breakage has not yet been completely eliminated, 0.37% is enough to instill confidence in LSX users. But the news gets even better--the same Creighton study showed that 75% of irretrievable instrument fragments could be bypassed and filled to length. This result is a factor of the unique LSX spade-shaped blade, which can leave ample room for bypassing on either side. This means that the chance of leaving a short fragment in the root without being able to bypass it is approximately 1 in 1,000.
With the EndoVac, there is no positive-pressure delivery of irrigant inside the root canal itself. Irrigants are drawn into the canal through a MacroCannula that evacuates gross debris, and the smaller debris is drawn through a MicroCannula placed at full working length. The MicroCannula is a true engineering and manufacturing phenomenon. Within the last 0.7 mm of the MicroCannula tip are 12 laser-drilled holes, each 100 mm in diameter. It is through these suctioning holes that liquid EDTA, sodium hypochlorite, or other irrigants are drawn down and evacuated safely away.
“All positive pressure [needle] irrigation systems can eject irrigants through the apical termination and also fail to circulate irrigant in the critical last few millimeters. Thus, micro-organisms and their by-products remain in the most critical apical area of the canal,” explains Schoeffel. “In 2009, Desai (JOE 2009, pgs 545-549) demonstrated that the safety features I developed were effective, while Nielsen (JOE 2007, pgs 611-615) and Hockett (JOE 2008, pgs 1374-1377) demonstrated significantly superior canal cleanliness and 100% biological control.”
To finish the case, Discus introduced the HotShot cordless backfill obturation device to the endodontic community. This product became the ideal solution for back-filling behind the 5-mm length SimpliFill Apical Plug. HotShot has been a huge hit as it couples the clinical benefits of warm backfill with the freedom of a cordless design.
“LightSpeedLSX is the most flexible rotary NiTi instrument in the world and the most effective at cleaning the apical third, especially in curved canals,” says Senia. “Though the traditional classic LightSpeed technique was successfully used by thousands of dentists for many years, we’ve known that eventually we’d need to respond to customer demands and offer a crown-down alternative.” After over 3 years of development and multiple rounds of prototypes, Discus launched the LightSpeedCRX™ (C stands for coronal) and LightSpeedMRX™ (M stands for mid-root) instruments in mid-2009. Clinicians appreciate the CRX because it eliminates the number of instruments needed during a typical coronal flaring procedure; because of its tapered shape, one CRX does the work of three Gates-Glidden drills. The benefit of MRX is that it creates a smooth, funnel-like shape through the mid-root, leaving the tough-to-reach apical third for LSX. This is a very unique approach, as each instrument type (CRX, MRX and LSX) is designed and optimized to clean and shape its specific third of the canal.
At the same time Discus introduced CRX and MRX to the endodontic community, the company also released the HotShot’s sister product—the HotTip. This cordless device offers an alternative for doctors using a warm vertical compaction technique, and is also an ideal tool for eliminating voids during the incremental backfill process utilizing HotShot.
“What we’ve got here is a product line that puts patients first, improves outcomes, protects clinicians, and provides support,” says Vice President of Global Marketing Jennifer McNally. “Irretrievable broken instruments, irrigation accidents, and poor fills are concerns that all doctors have to some extent. We take pride in offering a system that can be easier, safer, and more worry-free for our customers.”
Discus “Mentors” teach small, private continuing education (CE) courses often in their own offices. When doctors are making a major purchase that has significant practice management implications, they prefer to speak to a wet-fingered dentist actually using the product. “We’ve learned two important lessons as we’ve hosted CE courses over the years: (1) doctors prefer to talk to other doctors before, during, and after the purchase, and (2) bigger is not better,” says Senia. In a smaller group setting, participating doctors are able to receive the one-on-one attention they often need to gain understanding and confidence in these new techniques. It also allows them to establish a close relationship with the mentor, one they can turn to later if they need additional help.
The Discus SMART Endodontics Mentor program begins with two courses offering a total of 11 CE units. The first three units are completed as a series of online webinars from the comfort of one’s own home or office. The advantage of this approach is that a participant can proceed at his or her own pace and view the material again if necessary. It also gives one a sense of the philosophies that support SMART Endodontics so they will better know if it is the right system for them before investing more time, effort, and money. The next eight units are mostly hands-on experience with the techniques and equipment, and are taken at one of many locations around North America. “Our biggest competitor is inertia,” says Senia. “Change introduces uncertainty and this program can provide the skills and confidence to help eliminate that uncertainty.”
In 2010, Discus will hold over 120 small hands-on courses. In fact, they plan to host courses every other week at their corporate headquarters in Culver City. “Whether you’re from Southern California or not, we’d love to invite every doctor to come out to LA so we can show you around the office and welcome you to the Discus family,” says CEO Steve Semmelmayer.

RACINE, WI – Science has shown that irrigants are more effective when they are electro-mechanically activated. Acoustic streaming and cavitation of endodontic solutions has been shown to significantly enhance cleansing of difficult anatomy. Studies have shown that low frequency (Sonic) oscillation (160-190Hz) was not sufficient in creating acoustic streaming or cavitation within the canal space.
EndoUltra™ is the only cordless, compact, battery operated piezo ultrasonic (40kHz) activation device. Only EndoUltra™ is capable of producing acoustic streaming and cavitation in small canal spaces, resulting in significantly improved debridement, disruption of biofilm, improved penetration of irrigants into dentinal tubules, and the removal of vapor lock. Resulting in improved outcomes.
