A12 INDUSTRY NEWS Dental Tribune U.S. Edition | May 2019 New bulk fill composite easily and quickly adjusts to tooth ByEDr.EJfsephEKim When it comes to composite restorations, dentists are often asked to sacrifice speed for quality, or quality for speed. This has been especially true when it comes to bulk fill composites, which brought the promise of larger increment sizes, but required spe- cialized equipment or were other- wise difficult to handle. Now, clinicians can have a composite that easily adapts to the tooth and can be used in a true bulk fill technique. RE- VEAL® HD Bulk is BISCO’s new bulk fill light-activated restorative composite, op- timized for simpler and faster posterior restorations. REVEAL HD Bulk combines appropriate handling, depth of cure and polishability, which enable clinicians to provide patients with functional and es- thetic composites while saving valuable chair time. REVEAL HD Bulk enables layering in- crements up to 5 mm due to its predict- able depth of cure. This feature is ac- companied by low volumetric shrinkage, high flexural strength and excellent ra- diopacity, resulting in long-lasting, dura- ble restorations. While REVEAL HD Bulk is indicated for all direct and indirect restorations, clinicians will appreciate the significant time savings bulk filling provides, especially in posterior teeth. CDA BOOTH NO. 400 AAPD BOOTH NO. 1601 Like other restorative compos- ites, 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 with significant separating force will ensure excellent adaptation to the proximal margins, as well 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 manu- facturer instructions. When possible, it is ideal to selectively etch the enamel sur- faces where the composite is intended prior to application of the bonding agent, resulting in minimal long-term margin- al leakage and dentinal sensitivity issues. Depending on operator preference, a flowable composite resin may be used in the deepest and least accessible areas of the preparation, including undercuts and the cavosurface 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 due to its unique chemistry, care should be taken to avoid unnecessary exposure to light, including from ambient and over- REVEAL HD Bulk is BISCO’s new bulk fill, light-activated restorative composite, which is optimized for simpler and faster posterior restorations.

Finally, the restoration can be finished with fine diamonds and finishing car- bides, followed by finishing points. It is worth noting that since REVEAL HD Bulk’s viscosity has been tuned for bulk fill applications, it is preferable to limit occlusal carving and shaping to primary anatomy prior to curing. After curing, greater detail may be added with finish- ing burs, as needed. Alternatively, when darker or opa- ceous restorative composite shades are required, REVEAL HD Bulk can by placed and cured short of the occlusal cavosur- face margins. The final layer can be a traditional restorative composite in an ideal shade and opacity. Because REVEAL HD Bulk is universally compatible, it will serve as an excellent base under all light- activated restorative composites. REVEAL HD Bulk has been specifically designed to address the needs of clini- cians who require the speed of a bulk fill restorative composite without sacrific- ing strength and ignoring esthetics. It is currently available in the most com- monly used shades, from A3 to B1, in both syringe and unit dose form. At CDA Presents in Anaheim, visit booth No. 400.

Barrier protection critical with gloves While caring for their patients, dental and health care professionals are constantly exposed to bodily fluids that may carry viruses and other infectious agents. It is therefore critical that the gloves these profession- als use provide the best possible barrier protection. Many types of gloves are available today, but it is im- portant to know that not all gloves have the same bar- rier capability, depending on the type of material used. For example, natural rubber latex gloves have long been acknowledged for their very effective barrier proper- ties, while non-latex gloves, such as vinyl (polyvinyl chloride), have inferior barrier capability as shown by numerous studies. Quality, safety top priorities Other synthetic gloves, such as nitrile and polyisoprene, perform much better than vinyl but are more costly, es- pecially polyisoprene gloves. Using gloves with inferior capability could expose both the patient and user to harmful infections. Malaysia is the world’s largest medical gloves exporter (latex and nitrile). Both quality and users’ safety are of top priority to the nation’s glove industry. To this end, a quality certification program (the Standard Malaysian Glove, or the SMG) has currently been formulated for latex examination gloves. Stringent technical specifications All SMG-certified gloves must comply with stringent technical specifications to ensure the gloves are high in barrier effectiveness, low in protein and low in al- lergy risks, in addition to having excellent comfort, fit and durability — qualities that manufacturers of many synthetic gloves are trying to achieve. Latex gloves are green products, derived from a natu- ral and sustainable resource, and are environmentally friendly. (You can learn more online by visiting www. smgonline.biz or www.latexgloves.info). The use of low-protein, powder-free gloves has been demonstrated by many independent hospital studies to markedly reduce the incidence of latex sensitization and allergic reactions in workplaces. More important, latex-allergic individuals donning non-latex gloves can now work alongside their cowork- ers wearing the improved low-protein gloves without any heightened allergy concern. However, for latex- allergic individuals, it is still important they use ap- propriate non-latex gloves, such as quality nitrile and polyisoprene gloves, which provide them with effective barrier protection. Extensive array of brand, prices Selecting the right gloves should be an educated consid- eration to enhance safety for both patients and users. For decades, gloves made in Malaysia have been synon- ymous with quality and excellence, and they are widely available in an extensive array of brands, features and prices. Dental gloves can be sourced either factory di- rect (www.mrepc.com/marketplace) or from established dental products distributors in the United States and Canada. (Source: MREPC)
