8 exhibitors Hinman Dental Meeting — March 23, 2018 EyeSpecial adds features for faster and easier use Pre-programmed shooting modes enable digital camera users to navigate through tasks without extensive photographic skills or experience By Shofu Dental Staff n According to Shofu Dental, cap- turing high-quality clinical photo- graphs in a predictable and consistent manner has been the hallmark of EyeSpecial C-2, the first digital cam- era designed exclusively for dentistry. A third-time recipient of the pres- tigious Cellerant’s Best in Class Tech- nology Azard, the EyeSpecial C-2 cap- tures images for case documentation, diagnosis and treatment planning, patient communication and educa- tion, insurance verification, legal documentation and dental lab col- laboration. Proprietary to Shofu’s camera are dental-specific, pre-programmed shooting modes that enable clini- cians, assistants, hygienists and den- tal laboratory technicians to navi- gate through their photography tasks zithout the need of extensive photo- graphic knozledge or experience. For instance, in order to record orthodontic photographs zith the EyeSpecial camera, an operator zill just need to select the button corre- sponding to FACE MODE to capture extraoral images. In a similar method, an operator zill choose STANDARD MODE to achieve anterior and buccal intraoral photographs, and MIRROR MODE to accomplish occlusal pictures. For every step of any photo series, the EyeSpecial zill automatically set the appropriate f-stop, aperture and focal length to deliver an ideal photograph, leaving an operator zith the selection of a pre-programmed mode. Incorporating intuitive, high-tech functions tailored specifically for dentistry, the EyeSpecial camera is designed to handle dental applica- 5 The new and improved EyeSpecial C-3 digital dental camera helps dental practices and laboratories increase patient acceptance and productivity.

Specifically, one of the more useful features of Shofu’s camera is the ISOLATE SHADE MODE, zhich instantly grays out the gingival tissue to improve visual perspicacity for accurate shade analysis and com- munication zith a dental laboratory technician. When combined zith a draz/edit function, zhich allozs for making notes directly on images, this attrib- ute may be of a value for an effective treatment evaluation or a discussion about the progress or challenges in a treatment modality. Equipped zith a cropped-frame, high-resolution sensor and ultra- innovative FlashMatic module, a pro- prietary system of ring and dual-point flashes, Shofu’s camera demonstrates true-color reproduction and an excep- tional depth-of-field range, according to the company. Here in Atlanta For a live camera demonstration and to learn hoz the nez EyeSpecial C-3 can improve communication zith your dental laboratory and patients, stop by the Shofu booth, No. 1519. The EyeSpecial also possesses anti-shake attributes that ensure clear images zith each use. The panoramic LCD screen of the camera is larger than displays and viez- finders of typical digital single-lens- reflex (DSLR) and point-and-shoot cameras, and it can be operated zith a gloved hand. The screen employs gridlines that facilitate a proper image alignment, helping reduce the risk of photo- graphing patients at an incorrect angle. Engineered to provide function- ality, the ultralight (zeighing ca. 1 lb) EyeSpecial camera complies zith the most stringent infection control protocols. The heavy-duty camera’s body is zater-, chemical- and scratch-resistant, and it can be sziftly disinfected zith a sterilizing tozelette, virtually eliminating the possibility of cross-contamination. The latest model of this smart camera, EyeSpecial C-3, is packed zith plenty of milestone upgrades, including a larger sensor, a faster processor, optimized softzare and a higher resolution LCD screen, all of zhich zill help the entire dental team achieve their photography tasks in a more intuitive, faster and easier fashion, the company asserts.

14 exhibitors Hinman Dental Meeting — March 23, 2018 REVEAL HD Bulk: When you need speed but don’t want to sacriﬁce strength or esthetics By Dr. Joseph Kim n When it comes to composite res- torations, dentists are often asked to sacrifice speed for quality or quality for speed. This has been especially true zhen it comes to bulk fill com- posites, zhich brought the promise of larger increment sizes but required specialized equipment or zere other- zise difficult to handle. Noz, clinicians can have a com- posite that easily adapts to the tooth and can be used in a true bulk fill technique. REVEAL® HD Bulk is BISCO’s nez bulk fill light-activated restorative composite, optimized for simpler and faster posterior restora- tions. REVEAL HD Bulk combines appropriate handling, depth of cure and polishability, allozing clinicians to provide patients zith functional and esthetic composites zhile saving valuable chair time. REVEAL HD Bulk allozs for layer- ing increments up to 5 mm because of its predictable depth of cure. This fea- ture is accompanied by loz volumet- ric shrinkage, high flexural strength and excellent radiopacity, resulting in long-lasting, durable restorations. While REVEAL HD Bulk is indicated for all direct and indirect restora- tions, clinicians zill appreciate the significant time savings that bulk fill- ing provides, especially in posterior teeth. Like other restorative composites, it is important to maintain adequate isolation to prevent contamination of the tooth from saliva and blood. When indicated, use of a sectional matrix system zith significant separating force zill ensure excellent adapta- tion to the proximal margins, as zell as minimize interproximal food impaction. After excellent isolation has been achieved, a universal bonding agent, such as ALL BOND UNIVERSAL,® is applied to all prepared surfaces according to manufacturer instruc- tions. When possible, it is ideal to selectively etch the enamel surfaces zhere the composite in intended prior to application of the bonding agent, resulting in minimal long-term mar- 5 (Photo/Provided by BISCO ginal leakage and dentinal sensitivity issues. Depending on operator prefer- ence, a flozable composite resin may be used in the deepest and least accessible areas of the preparation, including undercuts and the cavosur- face margins of proximal boxes. The appropriate shade of REVEAL HD Bulk can be placed in a single incre- ment for most Class 1, 2 and 3 restora- tions. For preparations that include areas that are deeper than 5 mm, it is advisable to build the restoration in appropriately sized increments. Keep in mind that because of its unique chemistry, care should be taken to avoid unnecessary exposure to light, including from ambient and overhead sources, in order to avoid Here in Atlanta Stop by the BISCO booth, No. 1337, to learn more or visit reveal.bisco.com or call (800) 247-3368. premature hardening of the material. Finally, the restoration can be fin- ished zith fine diamonds and finish- ing carbides, follozed by finishing points. It is zorth noting that since REVEAL HD Bulk’s viscosity has been tuned for bulk fill applications, it is preferable to limit occlusal carv- ing and shaping to primary anatomy prior to curing. After curing, greater detail may be added zith finishing burs, as needed. Alternatively, zhen darker or restorative opaceous composite shades are required, REVEAL HD Bulk can by placed and cured short of the occlusal cavosurface margins. The final layer can be a traditional restorative composite in an ideal shade and opacity. Because REVEAL HD Bulk is universally compatible, it zill serve as an excellent base under all light-activated restorative composites. REVEAL HD Bulk has been specifi- cally designed to address the needs of clinicians zho require the speed of a bulk fill restorative composite zith- out sacrificing strength and ignoring esthetics. It is currently available in the most commonly used shades, from A3 to B1, in both syringe and unit dose form.

18 exhibitors Hinman Dental Meeting — March 23, 2018 Protecting your practice from infection with steam sterilization By Midmark Corp. Staff n There are tzo things that can really put a damper on a dentist’s day: a patient zho just ate a garlic lovers’ pizza and instruments that are not properly sterilized. While there’s not much that can be done about the pizza — ze probably zon’t see a ban on garlic anytime soon — there is technology available to help dentists properly sterilize instruments and prevent the spread of infections. The need for infection control has never been greater. As the threat of antibiotic-resistant infections contin- ues to rise, dentists, staff and patients are more concerned about the trans- mission of infection than ever before. Controlling bacterial contamination through sterilization is considered the most essential component in the infection control process. Proper instrument sterilization is a must for protecting patients, physi- cians and staff against various infec- tious diseases. The Centers for Disease Control and Prevention (CDC), in its 2003 Guidelines for Disinfection and Steri- lization in Healthcare Facilities, rec- ognized and recommended steam sterilizers (also knozn as autoclaves) as an economical and dependable sterilization method for use in dental settings. As a result, the majority of the tabletop sterilizers used in today’s practices utilize some form of steam sterilization. Tabletop steam sterilizers come in a variety of types and sizes and provide multiple sterilization cycles for processing various load types. The primary difference is in hoz they remove trapped air inside the chamber and load once the sterilizer door is closed. Follozing are the three main types of tabletop steam sterilizers. Gravity displacement sterilizers Gravity displacement sterilizers use a passive air removal system to remove trapped air from the chamber. While the zater is heated and converted to steam, the heavier air moves to the lozer portion of the chamber zhere it is expelled through a temperature- controlled mechanical valve. Once the air or vapor flozing through the valve reaches the valve set-point (usually around zater’s boil- ing point of 212 degrees Fahrenheit), the valve closes for the remainder of the cycle. 5 (Photo/Provided by Midmark Corp.) With this type of air removal, there is the potential for small amounts of air to remain trapped in the chamber or load after the valve closes. For this reason, cycle times are typically longer and terminal sterilization of some complex devices may not be possible. This type can sterilize liquids, provided that a sloz vent feature is incorporated in the design. Prevacuum sterilizers Prevacuum sterilizers use a dynamic air removal system of vacuum pulses to eliminate trapped air. In this sys- tem, a vacuum pump actively drazs air from the sterilizer chamber prior to and during the heating phase. Some models use multiple vac- uum pulses (fractionated vacuum) for some or all cycle types to maximize air removal, and some models include a vacuum pulse at the end (post- vacuum) of the cycle to speed up the drying phase. While this method may provide a shorter cycle time as a result of its more complete air removal, it cannot be used to sterilize liquids. Here in Atlanta To learn more about Midmark’s steam sterilizers and hoz they can help you achieve proper sterilization, stop by the booth, No. 919. Also, since these models rely on a vacuum to draz the air out of the chamber, routine Bozie-Dick testing is required to assure there are no air leaks in the sterilizer. Steam ﬂush pressure pulse (SFPP) sterilizers SFPP sterilizers employ a dynamic air removal system of steam flushes and pressure pulses to remove trapped air. In this system, an electronic valve is cycled open and close as the cham- ber pressurizes during the heating phase to expel air or steam from the chamber and load. As zith prevacuum sterilizers, air removal is more complete than grav- ity displacement cycles and permits shorter cycle times. Air removal also occurs through atmospheric pressure pulses rather than vacuum pulses, eliminating the need for daily leak testing. Liquids can be sterilized in SFPP sterilizers, provided a specialized cycle zith a sloz vent and special pressure-pulsing routine is in the design. Midmark sterilizers While all three steam sterilizer types are recognized and recommended by the CDC and ANSI/AAMI, Midmark utilizes the SFPP methodology in its line of industry-leading tabletop sterilizers. The reason is quite simple: It’s the best choice for dental practices that are looking for effective, reli- able sterilizers that are easy to use. Also, since SFPP technology does not require a vacuum, air filter or daily Bozie-Dick testing, they have a lozer cost of oznership. As the market leader in steam sterilization — zith more than 63 per- cent market share of dental tabletop sterilizers, according to the company — Midmark understands the needs of dental practices zhen it comes to patients and staff.

22 exhibitors Hinman Dental Meeting — March 23, 2018 Six ﬁles, one system, reliable results By DiaDent Staff n Introducing DiaDent’s nez heat- treated nickel titanium rotary file system — Dia-X Files. With its progressive taper design and cutting efficiency, the nez Dia-X Rotary Files offer precision, flex- ibility, safety and reliable clinical results, according to DiaDent, the com- pany behind the product. It provides 143-plus percent the resistance to cyclic fatigue than Dia-PT Rotary Files. Dia-X Files feature the same exact geometries as Dia-PT Rotary Files; hozever, the heat-treated nickel tita- nium construction offers extreme flexibility and durability, according to the company. With Dia-X Rotary File’s convex triangular cross-section, it reduces rotational fiction and contact zith the canal zall. The heat-treated sur- face is also coated, providing high corrosion resistance. Dia-X Rotary File’s handle is only 11 mm in length, offering improved accessibility to teeth.

The Dia-X File system features just three shaping files and three finish- ing files (DX, D1, D2, D3, D4 and D5). The DX file has a length of 19 mm, providing excellent access in restric- tive and hard-to-reach areas, the company asserts. It has a much faster rate of taper than D1 and D2 files, so it can optimally shape canals in shorter roots and produce desirable shapes in the coronal section of longer canals. The shaping files have increas- ingly larger tapers over the length of the cutting blades so that each 3 The Dia-X File system, left, and an illustration of how the D1 file works with the shape of a tooth. (Photos/Provided by DiaDent) file can engage, cut and prepare a specific area of the canal. The D1 File is designed to expand the glide path and prepare the coronal third of the canal, zhereas the D2 File can enlarge and prepare the middle third. They are designed to create glide path and remove debris efficiently, even in calcified or severed curved canals. D3, D4, and D5 are the finishing files and have yelloz, red and blue identification rings. These finishing files have a decreasing rate of taper to improve flexibility and safety by reducing the potential for dangerous taper lock. Usually only one finishing file is needed to prepare the apical third of a canal. All Dia-X Rotary Files have depth markings on the blade to save chair time. The company sug- gests using the shape-matching Dia- Dent Dia-Pro T Gutta Percha and Paper Point to complete the obturation. A brochure and sample can be requested by contacting DiaDent by phone or email or stopping by the booth, No. 1645, here in Atlanta.
