Because it requires no separate etching and bonding steps and has greataesthetics, it is the ideal cement to use for your everyday cementation needs.Shelf-life without refrigeration and colour stabilityDuring the development phase of SmartCem2, it was recognised that thetraditional components used for the initiation of curing would not be suitablefor a self-etching, self-adhesive product. Since it was desired to have a dualcuring mechanism in SmartCem2, the formulation would require dual initiatorsystems. Thus, due to the use of acidic components within the formulationsof SmartCem2, both the visible light and self-cure initiators would be affected.Both initiator systems utilise basic components (e.g. amines), and thesecomponents would be expected to react with the acidic adhesion promoter.This would result in compromised storage stability if the components wereallowed to come in contact with each other in the package.A further complication involved the interaction of the acid componentswith the traditional benzoyl peroxide (BPO) self-cure initiator. This interactionwould also lead to degradation of the peroxide initiator over time, if allowedto be in contact with the acidic components during storage. Thus, theformulation of SmartCem2 needed a fresh look.The polymerisable resins are used in other DENTSPLY products, suchas Esthet•X ® Micro-matrix Restorative. These resins provide structuralreinforcement of the resin cement, as well as strong cross-linking of thepolymer network upon polymerisation. As a result, the mechanical andphysical properties of SmartCem2 are enhanced and strengthened.The adhesion promoter, PENTA, is well known to DENTSPLY adhesiveproducts, including Prime&Bond ® NT Universal Dental Adhesive System.This phosphoric acid modified monomer has been demonstrated to interactdirectly with the calcium in tooth structure, resulting in strong covalentbonding to the tooth surface (*reference 1).Micro-leakageThe extent to which a cement is able to seal the marginal areas around anindirect restoration can be demonstrated through the use of the in-vitro test forresistance to microleakage. In this test, non-carious human molars were used.Two class V cavity preparations were made on opposite sides of each noncarioushuman molar with the occlusal margins in enamel and gingival marginsin cementum. SmartCem2 showed no leakage in Class V Cavities, enamel anddentine, whereas other market-leading self-adhesive cements showed at least50% leakage to the apex.Based on research findings from the development of Xeno ® IV Dual CureSelf-Etching Dental Adhesive, the new, proprietary acid resistant amine wasincorporated as part of the visible light initiator system in SmartCem2.This amine is not reactive with the acidic components of SmartCem2,which makes the composition stable to storage conditions, ensuring that thevisible light activation of SmartCem2 will occur predictably during the life-timeof the product.The new, proprietary ingredients include the photoinitiator system, as well asthe self-cure reactive components of the dual cure material. The glass filler(69% by weight, 46% by volume) used contains fluoride fillers, similar to thoseused in other restorative products noted above.Bond StrengthsBoth the dual-cure and the self-cure modes were examined. As has been notedwith previous dual cure materials, exposure to visible light as part of the curingprocess generally leads to higher bond strengths, due to the more energeticconditions of curing. SmartCem2 showed the highest bond strengths to toothstructure when compared to 3 other market-leading self-adhesive cements.In-vitro Microleakage Gingival Dentine MarginsA second research problem involving the self-curing system within theSmartCem2 provided a novel, proprietary initiating system that also resultedin a shelf-stable material. In this case, the traditional benzoyl peroxide/aminesystem was replaced with a hydroperoxide/non-amine system.This new self-cure initiating system has several advantages;• The new system is insensitive to the acidic components of SmartCem2• The degradation of the traditional BPO component that leadsto changes in working and setting properties is eliminated• The degradation of the traditional BPO component with exposureto heat and prolonged storage times is eliminated, and• The effect of colour change of the materials using a BPO/amineself-cure is also eliminated.The overall effect of this new self-cure initiator system results in a shelf-stableproduct with stable and predictable handling properties (e.g. consistent workingand setting times), without color changes of the cured SmartCem2 cement overtime. Because the heat sensitive BPO/amine components were replaced,SmartCem2 has a significantly improved shelf-life without the need forrefrigeration of the product.Easy ApplicationThe real benefit of SmartCem2 is the application and handling compared tothe other self-adhesive cements on the market. Because it uses an automixsyringe, it means you avoid the hassle associated with hand mixing and ensuresyou always have enough material to hand (unlike capsules where you can easilyrun out of material mid-way through the procedure, or have excess materialwhich is wasteful.Gel-PhaseThe “gel-phase” of SmartCem2 ensureseasy clean-up of material and can beinitiated quickly with a few seconds of acuring light, reducing the waiting timeand ensuring a quicker procedure.To arrange for a free demonstration ofSmartCem2 in your practice, call todayon +44 (0)800 072 3313 to be one of the first to see this great new product.Bond Strengths to Tooth StructureREFERENCES1 Latta MA, Shear Bond strength and physiochemical interactions of XP Bond.

Dynamics Sep 08 20/8/08 09:02 Page 7ProTaper ® UniversalA Complete Endodontic Systemfor Endodontists and GDPsWhether you are an experienced endodontistor a clinician eager to improve your root canaltreatments, the ProTaper Universal range fromDENTSPLY Maillefer offers a solution to meetyour clinical needs.Built upon the enormous success of the existing ProTaper range, the Universalsystem has been enhanced and is one of the most simple, efficient and safesystems for root canal treatment on the market today. Due to this, the ProTaperUniversal NiTi treatment files are now the most popular files on the market in theUK (external Q1, 08 SDM data) and their use is being taught to undergraduatesin the majority of the dental schools with great success.As a true system-based approach, the ProTaper Universal range now includessimple solutions for treatment, warm obturation and re-treatment.TreatmentIn order to effectively eradicate infection from root canals and achieve truethree-dimensional fillings, the canals must be shaped effectively. ProTaperUniversal offers solutions for rapid and high quality canal shaping.Due to the unique multi-tapered shape that each ProTaper file exhibits alongit’s cutting portions, only 3 ProTaper treatment files are needed to efficientlyand effectively shape the majority of canals for optimal cleaning and truethree-dimensional filling, saving time.The other major benefit of ProTaper Universal over most other NiTi systems isthat they achieve a minimum of 7% taper at the apex, allowing for optimalirrigation, even in more difficult canals. This is paramount to allow for effectiveeradication of bacteria from the root canal system and therefore for success of thetreatment. In cases with severe apical curvature, the clinician can choose to usethe NiTi ProTaper for Hand Use instead of the rotary version. This ensures that thebenefits of NiTi and the system are seen in cases where the clinician may havepreviously had to revert back to stainless steel files if using another NiTi system.In addition to this, ProTaper caters for more types of clinical cases than most othersystems on the market due to the availability of the files in lengths 31mm as wellas 21mm and 25mm.The colour-coded and easy-to-follow protocol is the same sequence for all canals,simplifying the procedure. Because they have a guiding tip with rounded ends,deviations from the canal are minimised and can be used to safely treatanatomically difficult cases.In summary, more difficult canals are easier to prepare with ProTaper Universalthan most other systems, as well as requiring fewer instruments and achieve atapered preparation large enough for irrigation and obturation withoutunnecessarily enlarging the constriction.ObturationProTaper Thermafil provides an effective and simple solution to achieve acomplete, three-dimensional seal of the root canal system so that re-occurrenceof bacterial infection is prevented . These obturators have proven to have excellentsealing capacity and are able to penetrate lateral canals and dentinal tubules,increasing the quality of the seal. Because they have colour-coding to matchthe corresponding file, the simplified procedure saves time compared withtraditional techniques.ProTaper cold gutta percha points and paper points are also available andperfectly match the shape of the finishing files.Re-treatmentThree re-treatment files: D1, D2 and D3 are now are available aspart of the ProTaper Universal system and have been specificallydesigned to remove obturation material from the root canal. D1has a cutting tip for effective penetration into the obturationmaterial in the coronal third. D2 and D3 are used in the mid andapical thirds of the canal respectively and have non-active tipsthat have been designed to closely respect the path of the canal.To aid removal of zinc-oxide-eugenol based soluble pastes,DENTSPLY’s DMS IV solvent can be used to soften the pasteprior to use of the re-treatment files.DENTSPLY support and trainingDENTSPLY Maillefer is committed to providing you with high quality, reliableand effective solutions for all stages of root canal treatment to make procedures,simpler, faster and safer.

Dynamics Sep 08 20/8/08 09:02 Page 9Oraqix ® 25/25 mg/g periodontal gel (lidocaine, prilocaine)Air polishingNeed aquick LA fix?Use Oraqix!Like many hygienists, with some fear and trepidation at the time, I participatedin further training to be able to administer local infiltration anaesthesia in 1991and inferior dental blocks in 2002. With clinical experience under my belt, I amglad to say I’m confident and competent in both techniques and now use themregularly in my daily practice.However, I still encounter patients who refuse local infiltrations and blockinjections. Why? For many, memories of bad experiences still present in theirminds, stating that they would rather put up with a little discomfort of thetreatment than have an injection.In the past, I have tried applying topical anaesthetic gel to the surface of thegingiva as a solution to the problem. To date, I have had nothing more to offerthe patient than verbal encouragement and careful patient management!So where does Oraqix (25/25mg per g periodontal gel, lidocaine, prilocaine) fit in?For DCPs trained in administering local anaesthesia, Oraqix is a lidocaine 2.5%prilocaine 2.5% topical anaesthetic liquid. Oraqix gives effective localised gingivalanaesthesia for scaling and tooth surface debridement. It can be easily applieddirectly into the periodontal pocket with the specially designed Oraqix Dispenser,which is sterilised in between patients. The anaesthetic cartridges of Oraqix andblunt-tip applicator are disposable.Alison GrantAlison Grant qualified as a Dental Hygienist from BristolDental Hospital in 1987. She has gained a wide variety ofexperience in NHS & private practice and worked as a staffhygienist in the hospital setting treating patients with specialneeds and advanced periodontal disease. Alison currentlyworks in specialist periodontal practice, is a tutor for theHygiene/Therapy diploma at Bristol Dental Hospital andregularly lectures with the South West Dental PostgraduateDepartment providing continuing professional developmentfor members of the Dental Team.As a Dental Hygienist who qualified 21 years ago, I have always endeavoured and viewed it as mypriority, as a dental professional, to keep up to date and train in new techniques and skills to improvemy patient care.I have found there are many benefits to using Oraqix in a variety of clinicalsituations, which include:• The liquid easily flows into the contours of the periodontal pocketand then converts into a gel to stay in situ• The gel can be re-applied if longer treatment is required, with amaximum dose of five cartridges• The metal blunt-tipped applicator can be bent to improve access inposterior sites. I start with the tip straight for anterior periodontalpockets and then adjust for the posterior teeth• Oraqix is time-saving as it is effective in 30 seconds after application,allowing more time for treatment. There is minimal post-proceduralnumbness as the duration is about 20 minutes• Patients have commented on how quickly it wears off after theappointment has finished, so there is no prolonged anaesthesiadiscomfort for them to endure• Ideal for periodontal pocket charting for patients with sensitive teethand gingivae• Ideal for patients who present with one tooth in each quadrant thatrequires deep scaling where it would be inappropriate to inject on bothsides of the mouth using traditional anaesthetic injections• Relieves the anxiety of those patients who dislike traditional injections• Improves the flexibility of management of treatment during anappointment. Oraqix’s speedy effectiveness has really been a hugebenefit to me as I can spend more time treating my patients.Thanks to the use of Oraqix, the needs of these patients are now met.No injections, but effective anaesthesia to provide detailed scaling andprobing in comfort. They are now happy and relaxed to return, relieved toknow that previous discomfort is all in the past.Widen your treatment options today!Air Polishing…One of the tips to building the aesthetic side of your dental practiceAir Polishing Equipment and Prophy PowdersAir polishing is a great alternative to standard rubber cup polishing. It is quicker, more effectiveand particularly liked by patients; meaning patients are prepared to pay a little extra for this “special”service. Bal Chana, Deputy Principal Hygiene and Therapy Tutor at Bart’s & The London, loves theair polishing feature in the Cavitron Jet Plus.Air polishing is not only indicated for use on heavy stains but can be used for a wide range ofapplications making it a cost effective and efficient piece of equipment. Bal says that due to thecombined feature of air polisher with the scaler in the Cavitron Jet Plus, it is quick and easy toswitch from one system to the other. Moreover, her patients prefer air polishing to traditionalstain removal methods because the result and the feel is so much better.IndicationsAir polishing uses a mild polishing agent, water and air through a mixing nozzle to remove stainand debris, allowing polishing of the tooth enamel. (Please note that air polishing is different toair abrasion, which uses an aluminium dioxide abrasive to remove tooth structure prior to thereplacement of restorations). Air polishing can be used:• For extrinsic stain removal• As a post-scale polish• During implant maintenance• Prior to placement of sealants and bonds• Prior to orthodontic band placement and prophylaxis of orthodontic patients• During periodontal surgeryTo find out more about how you can offer air polishing to build aesthetic dentistry in your practice,please call +44 (0) 800 072 3313.NOW AVAILABLEJET-Fresh (aluminium trihydroxide based) and PROPHY-Jet(sodium bicarbonate based) can be used in air polishing CavitronJet Plus unit which has a wireless foot pedal! PROPHY-Jet is awater-soluble powder with a mint flavour and allows excellent stainremoval. A clinical report stated that it is no more abrasive on theenamel than a rubber/prophy cup and pumice. JET-Fresh gives afresher, non-salty taste to the patients and can be used on patientswith a sodium-restricted diet. Because of the ingredients, the ‘clogging’possibilities are reduced compared to other powders.Citanest 3% with Octapressin• Standard and Self-Aspirating 1.8ml Cartridges(that fit the 2.2ml syringes); adaptors suppliedwhere necessary• Latex-free• Adrenaline-free• 40% less toxic than lignocaine 2Citanest ® 3% with Octapressin DENTAL Injection (prilocainehydrochloride and octapressin corresponding to felypressin) isavailable in 1.8ml, self-aspirating cartridges.It avoids thecardiovascular effects of adrenaline 1 .www.dentsply.com, www.dentsply.co.uk.

Dynamics Sep 08 20/8/08 09:02 Page 11RestorativesChemFil ® Molar CapsTemporary Cavity Restorationduring Root Canal Treatment– Current MethodsAn endodontic specialist is able to choose among several alternative methods to restore the cavityfollowing root canal treatment temporarily or permanently. DENTSPLY spoke to Dr. Claudia Barthel,senior physician at the Outpatients' Department for Restorative Dentistry at the Heinrich-HeineUniversity in Düsseldorf, about currently available materials for temporary cavity restoration, duringand after root canal treatment.Which dental materials can be principally used for coronal restorationsduring endodontic treatment, and what are their benefits and disadvantages?For temporary coronal restorations we have, for example, Cavit ® which can beapplied very easily. However, after only a few days - according to our research- it tends to become permeable. The same aspect applies to intermediaterestorative materials, so-called IRM, which also can be used only for a few days.Glass Ionomer cements exhibit a significantly longer durability and excellentimpermeability, although the higher price might be seen as a disadvantage.Capsule systems, in particular, permit a rapid and safe procedure with a highdegree of impermeability - the best solution in the case of temporary coronalrestorations of less than four weeks.For a permanent or long-term temporary coronal restoration, composite systemsare the material of choice with regard to sealing properties. However, processingis more complex and expensive due to the adhesive bonding procedure.What circumstances necessitate a temporary coronal restoration of a toothduring root canal treatment?A temporary coronal restoration is always needed, either during single-sessionroot canal treatments or during multi-visit treatments which require a root canaldressing. You also need to restore endodontically treated teeth prior to postinsertion, and prior to placement of definitive restorations when a tooth remainsunder observation.What are the decisive criteria for temporary filling materials?Temporary filling materials must exhibit maximum impermeability to ensure thesuccess of an endodontic treatment procedure. Any amount of bacterial leakageduring or following treatment can cause reinfection. It would be unjustifiable totake complex steps to avoid bacterial infiltration during root canal treatment, onlyto allow re-infection when placing the temporary coronal restoration. In additionto impermeability, the functional and, especially in the case of anterior teeth,aesthetic aspects must be considered. The selection of a compatible restorativematerial is further determined by the defined period of time it will remain in situ.What is your personal choice of temporary restorative material?Numerous studies on the quality of restorative materials are available, includinga number of our own diverse published studies. I routinely use glass ionomercement during endodontic treatment, because the overall composition of thismaterial provides the best compromise of high safety and durability of temporaryrestorations together with an acceptable cost factor.In the case of extended planning intervals, bonded composite systems are alsoa valid option - for permanent restorations or for observation periods until healingof the tooth is completed.What durability do you anticipate from glass ionomer cement restorations,for example the new DENTSPLY capsule system ChemFil Molar Caps?In general, I use glass ionomer cement for approximately four to a maximumof six weeks, for reasons of impermeability, which, according to our studies,can no longer be guaranteed after this period of time. It should be noted thatthe permeability is not necessarily determined by innate material properties,but rather due to other factors. For example, the soft medical dressing materialin the root canal or cavity can cause dysfunction. In any case, there are numerousparameters, which, in varying degrees of influence, limit the durability of atemporary restorative material. Duration of application of four weeks should besafe for glass ionomer cement restorations.IRM may indeed be less costly, but offer reliable sealing properties for only alimited period of time. Added to this, the patient themselves presents an unknownfactor if, based on unforeseen circumstances.

Of Endodonticsin Chapel Hill, USA.Currently, Senior Clinician at the Polyclinic for RestorativeDentistry at the Heinrich-Heine University in Düsseldorf.My use of Glass Ionomersin a Private PracticeBeing purely private, I am trying to get away from placing amalgams as a treatment of choice forchildren. But also I am uncomfortable using composites in youngsters whose caries status is in aconstant flux depending on their dietary habits and fads, which seem to change at the drop of a hat!My treatment of choice for early class I cavities is glass ionomers. Cavities can be prepared minimally,they adhere very well, the fluoride release seems to give some protection against secondary caries,and moisture control isn’t as vital as for conventional composites (very useful in the very young).The treatment plan after providing a glass ionomer is to monitor the tooth at futurecheck-ups, and to restore with composite when the child is older. Often though, allof the ionomer does not need removing. Just enough thickness to put a compositeover the top, later on.ChemFil ® Molar is the new glass ionomer from DENTSPLY. It is presented incapsules, in individually wrapped foil packs. The capsules are transparent, whichis useful for seeing how much material is within them. It is activated by the same‘press’ tool familiar to users of 3M ESPE glass ionomer materials, and dispensedwith the same trigger action gun that now mercifully seems to fit all GC,DENTSPLY and 3M ESPE products .The material mixes to a nice consistency, flows well into cavities and packsnicely without sticking to the instrument. Setting is quite rapid and the instructionsrecommend polishing after only four minutes. At the time I was road-testing thematerial though, the surgery was warm, and it seemed very solid after 2-3minutes.Personally, I am quite a fan of this type of glass ionomer material.I haven’t been using ChemFil Molar long enough to comment on its long-termwear, but in general, I have been placing restorations like this for about ten yearsnow, and have been very impressed with the wear rates, so long as the filling isnot too large.I also use the material for replacing fractured cusps in non-visible areas ofpremolar or molar teeth. The sort of fracture where a bit of cusp comes away froman MO, DO or MOD amalgam. Sometimes, it seems overly dramatic to crown orinlay such a tooth when it’s only a small piece missing, and the old restoration isfirmly in place. Just repairing the missing cusp can often be a good long lastingrepair and put off crowning an otherwise healthy tooth for many years.In summary then, I feel that ChemFil Molar Caps are a good, user-friendlypresentation of a very useful material. Setting time and wear resistance for suchmaterial has come on tremendously over the past few years and they haveestablished themselves as a material with a very important place in a preventativepractice, operating in a minimally-invasive way.Andy Bates, GDPSkipton, North Yorkshire10 DENTSPLY Dynamics | September - December 2008www.dentsply.co.uk11

No matter how high the wear and stain resistanceof a coating, it will not maintain a smooth surface or protect margins if the coating layer de-bonds from the substrate.Most competitive products have good adhesion to composites and compomer, but none have good adhesion to enamel.Lasting Touch contains the same adhesion promoters used in Prime&Bond ® NT to enhance adhesion to enamel.These adhesion promoters, combined with specially synthesized resin, provides excellent adhesion to enamel.A Lasting Touch coating resin-reinforced polish seals the margins and any microscopic cracks or fissures, ensuring minimumpatient post-operative sensitivity.Nano-Technology for high wear resistanceThe main drawback of current liquid polishers on the market is poor wear resistance. Generally, wear resistance can beimproved by adding fillers; however, this could change the opacity and thereby change the shade of the underlying substrate.Using nano filler can solve the opacity issue, but can also increase the viscosity, which will limit the filler loading level.To address this issue, Lasting Touch uses proprietary nano filler which has a minimum impact on viscosity. It is a clearformulation with a high filler loading level, ensuring high wear resistance.If you would like further information on Lasting Touch please contact DENTSPLY +44 (0) 800 072 3313or Henry Schein Minerva +44 (0) 8700 1020 43.Hi-Di No. 520 521 522 534 535 561 742ISO 001-010 001-012 001-016 225-014 225-016 247-016 160-009Product Code 60703520 60703521 60703522 60703534 60703535 60703561 60703742Medium Medium Medium Medium Medium Medium MediumGroup 2 - Special Price (Equivalent to 10 Hi-Di ® Diamond Burs plus 10 Hi-Di ® Diamond Burs FREE)Hi-Di No. 554 555 556 557 622 630 564ISO 171-014 172-014 173-016 173-013 171-016 174-022 243-022Product Code 60703554 60703555 60703556 60703557 60703622 60703630 60703564Medium Medium Medium Medium Medium Medium MediumHi-Di No. 501 635 753 566 672 546 544ISO 197-016 197-018 160-014 233-012 238-016 110-014 138-010Product Code 60703501 60703635 60703753 60703566 60703672 60703546 60703544Medium Medium Medium Medium Medium Medium Medium12 DENTSPLY Dynamics | September - December 2008www.dentsply.co.uk13

Dynamics Sep 08 20/8/08 09:02 Page 21ArtioQuixFilWhat are ArtioInstruments?An alternative to AmalgamHand fatigue can be a real problem in dentistry – and isn’t justconfined to dental hygienists. DENTSPLY recognised this whenthey developed the Artio range of hand instruments in closeconsultation with clinicians.The resulting range includes the most popular restorative and periodontal instruments with super-lighthandles and durable steel tips. Restorative shapes include plastics, carvers, pluggers and burnishers,and Periodontal instruments include scalers, hoes, Gracey, Langer and Columbia curettes. Essentially,Artio supplies everything you need on a day-to-day basis, and at an affordable price.Great care was taken in selecting the best materials to use in making Artio. The range has incrediblydurable steel tips developed under a special cryogenic process. This process means there are no harderstainless steel tips on the market; and the hardest steel tips DENTSPLY has even produced.The resin handle has also been designed to be one of the lightest available, yet is strong and resilientenough to withstand even the toughest sterilisation regimen, and if fully compliant with HTM 2010 andHTM 2030.For more information, or to book an appointment with your local DENTSPLY specialist to view the range,call +44 (0)800 072 3313 (Ash).Before, with amalgam After, with QuiXfil QuiXfil compulesOn January 1st 2008, Norway and Sweden banned the use of dental amalgam. While it isgenerally agreed that it is safe in the mouth, mercury released post-mortem is causing healthand environmental concerns. Dental Practice quoted Erik Solheim, the Norwegian minister forthe environment; “mercury is among the most dangerous of environmental toxins. Satisfactoryalternatives to mercury in products are available.”Focus onMouth CancerDENTSPLY is proud to support the Mouth CancerFoundation with its Artio range of hand instruments.For every Artio instrument sold, 50p is donated to theMouth Cancer Foundation.With Mouth Cancer Awareness Week from 16th-22nd November, ensure you have theinformation you need on Mouth Cancer, and how to detect it.This is the general term given to a variety of malignant tumours that develop in the mouth(oral cavity), throat (pharynx), voice box (larynx), salivary glands, nose and sinuses. In the UK,mouth cancer kills more people than cervical cancer and testicular cancer combined.Once discovered, treatment options vary and will depend on how early the cancer isdiagnosed or detected. Removal of the tumour, followed by radiotherapy may be suitablefor smaller tumours; chemotherapy is required in more advanced cases. The long-termsurvival rate is only 50% after 5 years, but early detection greatly improves prognosis.Risk Factors include Tobacco, Alcohol and types of the Human Papillomavirus, a groupof sexually transmitted viruses.Mouth Cancer FactsMouth cancer is one of the top ten most commonlydiagnosed cancers and accounts for more than7,800 new cases each yearIncidence has risen by 25% over the past 10 years5-year survival rate has not improved (50% overall)for the last few decades except in specialisedcancer centresMouth cancer is more common in men than women.However, the sex ratio in the UK has decreasedrapidly from around 5:1 fifty years ago to less than2:1 todayCommon symptomsA sore or ulcer in the mouth that does not healwithin three weeksNumbness or a lump anywhere in the mouthA white or red patch on the gums, tongue, or liningof the mouthDifficulty in swallowing, chewing or moving the jawor tongueThe timing of the ban in the UK is creeping closer, with a review dateof April 2009. Already, the use of amalgam is no longer taught in dental schools.The US Food and Drug Administration (FDA) reported earlier this month that“silver-coloured metal dental fillings contain mercury that may cause healthproblems in pregnant women, children and foetuses”. As part of a lawsuit, theFDA agreed to alert consumers about the potential risks on its website and toissue a more specific rule next year for fillings that contain mercury.Fewer patients have been opting for mercury fillings in the US in recent years,instead choosing lighter options, such as tooth-coloured resin composites.Composite fillings are now comparable to amalgam in strength and longevity,and further still satisfy the increasing demand from patients for an aestheticend result.QuiXfil is DENTSPLY’s alternative to amalgam, offering the perfect balanceof performance and price. It is indicated for Class I and II cavities, when safetyand performance are to be combined with a fast and efficient application.Advances in TechnologyGround-breaking advances in technology ensures durability, low shrinkageand speed of placement with QuiXfil:• The highest possible filler loading (66% by volume and 86% by weight)with a consistency that can be easily extruded from a compule andprovides high resistance to wear• Low material shrinkage at just 1.7%, for minimal post-proceduralsensitivity and longevity of restorations• A maximum depth of cure in just 10 seconds for 4mm increments,and prolonged working time of up to 100 secondsAffordable Alternative• QuiXfil is available in one universal shade which demonstratesa chameleon effect for great aesthetics, yet minimal inventory• 0.28g per compule of QuiXfil, 12% more material than some othercompule brands meaning “more for your money”In this changing market, patients expect more from their restorative treatments,even when it comes to posterior fillings. If you want to be prepared forthis demand, contact your local DENTSPLY Product Specialist to try QuiXfilfor yourself.20DENTSPLY Dynamics | September - December 2008www.dentsply.co.uk21

Dynamics Sep 08 20/8/08 09:02 Page 27Impression TakingImpression-Taking FAQsAquasil has been around for over 10 years now, with a wealth of clinical success.DENTSPLY understand that the clinician needs an impression to be right, the first time, to ensurean accurate fitting restoration, every time. Below are a handful of questions that DENTSPLY areasked about Aquasil Ultra and impression-taking, which we hope you will find useful.THE AQUASIL FAMILYAQUASIL BITEPOLYTRAYSSILFIXWhat makes Aquasil Ultra different from other impression materials?Aquasil Ultra uses a patented cross-linking web chemistry; quadrafunctionalmolecular structure for maximum strength. Aquasil Ultra’s wash material is atleast 40% stronger than 23 other leading wash materials tested. This means itmakes it easier to remove from the mouth, resisting tearing on removal.A new surfactant was added to Aquasil Ultra, making the material as hydrophilicas a hydrocolloid, without compromising its strength, and is 8 times more wettablethan polyether. It makes the detail reproduction unbeatable!Should I use Regular Set or Fast Set tray material?Regular set is ideal for one or more preps and for use in full mouth or quadranttrays. It is best to seat the tray 1 minute 10 seconds from the beginning ofsyringing the preparation for best results. Fast set is best used for one prep onlyand quadrant trays only. Seat the tray within 35 seconds from the beginning ofsyringing the preparation for best results.Can I disinfect Aquasil Ultra impressions?Aquasil Ultra material is not affected by either spraying or immersing (as per themanufacturer’s DFU) with bactericidal agents. No swelling, loss of accuracy orloss of wetting ability has been observed. Acceptable disinfectants includeIodophors, sodium hypochlorite (5.25%), and chlorine dioxide. Water-baseddisinfectants solutions are preferred.What about a Bite Registration material?Aquasil Bite is the bite registration material with the legacy quality of Aquasil.It is designed for accurate interocclusal and jaw relation records, and combineshigh final hardness with resistance to breaking. Trimming is easy because of itsA-silicone technology. Excellent detail reproduction and low linear dimensionalchanges make Aquasil Bite a high precision material. The combination ofsufficient working time and short setting time ensures dentist and patient comfort.So, now that I’ve taken the perfect impression, what provisional restorativematerial would you recommend?Integrity ® Provisional Crown&Bridge material with Fluorescence, and Integrity ®TempGrip Cement is the complete solution for temporary crown and bridgeprocedures from DENTSPLY. In a recent user evaluation among dentists, 69%rated aesthetics with Integrity better than those with their existing material and90% of dentists would or may purchase Integrity to replace their current material.If you would like a demonstration in your practice of the Aquasil Ultra range, thenplease contact us and ask for your local Product Specialist.Which tray adhesive should I use with Aquasil Ultra?We would recommend using an adhesive such as Silfix. It is a polysiloxane-basedadhesive which increases the adhesion between A-silicone impression materialsand the impression tray surface. Just brush a thin layer onto the inner surface ofthe tray (excess adhesive will not enhance adhesion) and allow to dry for five minutes.What about Impression Trays?Any selected tray should have thick enough walls and enough curvature to providelateral support for the tray impression material, to prevent distortion when pouringthe model. Trays also require enough overall rigidity to prevent distortion andrebound. Ash PolyTrays are available in three colour-coded sizes and are singleuse only. The lowers are able to be sectioned and used for small partials with thehandle and nylon adapter supplied.The History of Impression Materials26 DENTSPLY Dynamics | September - December 2008
