The EuroPerio Congress has established itself as the world’s leading conference in periodontology and implant dentistry. EuroPerio8 will take place from 3 to 6 June 2015 at the ExCeL London international exhibition and convention centre.

news4 EUROPERIO London 2015–3 June Latest market figures released by the Federation of the European Dental Industry (FIDE), in coopera- tion with the Association of Euro- pean Dental Dealers (ADDE), last month at the International Dental Show in Cologne, indicate rapid changes toward a digital dentistry manifesting in overall trends to a more global approach with group practices and consolidations throughout dental markets in Eu- rope. The organisation’s 2015 mar- ket survey also revealed that the number of European dentists has slightly increased to a total of 276,090 in 2014 compared to 270,045 the year before. A contrary trend showed in the number of dental offices and den- tal laboratories. While the num- bersoftheformerremainedflaton average, the total figures of labs in Europe has decreased in almost every surveyed country. Accord- ing to ADDE President Dominique Deschietere, given the growing numbersofpracticingdentiststhis development either indicates a trend to group practices or consoli- dation. While the number of dental technicians has remained steady or slightly decreased in all coun- tries except Hungary, the number ofdentalhygienistsincreasedinall countries of the survey. This devel- opment is especially prominent in the UK, with the number of dental hygienists growing distinctively compared to 2013. As Deschietere has put it, this seems to be a result of the evermore “bending of the laws” in this area. Onthesupplychannelsside,the percentage of direct sales from manufacturers remained steady in most countries, and the share of productspurchasedviae-mailorin- ternet is constantly, if only slightly, increasing compared to the previ- ous year. Further, the figures indi- catethatthesalesvolumeofequip- ment has dropped in 2014, while sales of sundries and consumables remained stable on average.“Den- tists continue to treat patients,” De- schietere pointed out. “Consum- ables and sundries, not new equip- ment like CAD/CAM units or intra- oral X-ray units, kept the figures up during the last years.” To this date the gathering of in- formation on new technologies seems to be the weak point of the survey. Although Germany shows ajumpinthenumbersofintra-oral scanners installed, most countries are not collecting data on the sub- ject so far, explained Deschietere. The annual ADDE/FIDE survey, which is conducted through its na- tional associations since 1998 and represents the interests of more than 960 dental dealer organisa- tions,coversthemostrelevanttop- ics and trends for the European Dental Industry, such as the num- ber of customers and end users, sales values for the main product categories,theuseofcomputerand e-commerce,salessegments,distri- bution channels as well as VAT charges and their impact on the market. Over10percentoftheadultpopu- lation suffers from chronic kidney disease (CKD) and those affected of- ten have poor health outcomes ow- ing to an increased incidence of car- diovascular disease compared with thegeneralpopulation.Ateamofre- searchers at Aston University re- centlyfoundthattreatingacommon gingival condition in CKD patients couldsignificantlyreducetheirrisk ofpotentiallyfatalheartdisease. CKDprogressivelyworsenskid- ney function, raises blood pres- sure, and can cause progressive vascular injury and heart disease. The latest research at the univer- sity suggests that increased mor- tality in people with CKD may be linked with chronic inflammatory conditions such as periodontitis, which causes gingival inflamma- tion, loss of the bone that supports the teeth and ultimately tooth loss. Previous studies have found that more than 85 per cent of peo- ple with CKD have inflammatory gingival problems, caused by inad- equate removal of dental plaque from between the tooth and gingi- val margin and made worse by im- paired immunity and wound heal- ing. Experts have identified that bacteriainthemouthcanenterthe bloodstream through periodontal conditions, causing blood cells to malfunction and leading to clots and narrowing of the arteries. Dr Irundika Dias of Aston’s School of Life and Health Sciences is currently leading a study into the underlying causes of in- creased cardiovascular disease and outcomes of accelerated pro- gression observed in people with CKD and periodontitis. She will observe how successfully treating periodontitis reduces oxidised lipids and inflammatory cell activ- ity in people with CKD, thereby loweringtheirriskoflife-threaten- ing heart disease. “This project has the potential to make a real difference for peo- plewithCKD.Ifwecanproveman- aging periodontitis reduces the threat of cardiovascular disease then it may well represent an effi- cient and cost effective treatment for CKD,” Dias stated. “In conjunc- tion with our study, I will be talk- ing to dental schools about alter- nativewaysofhelpingperiodonti- tis patients. It is vitally important to keep your gums healthy and have regular dental check-ups to avoid the onset of a disease that is very common, poorly appreciated bythepublicandcausestoothloss resulting in reduced quality of life.” The study will involve 80 peo- ple, including healthy volunteers and 60 people with CKD, both with and without periodontitis. Among these will be a group of 20 people with CKD and periodontitis who willberandomisedtohavethegin- gival condition clinically treated over a 12-month period. They will be reviewed at three-monthly in- tervalstoassessmarkersofcardio- vasculardisease,suchasoxidative stress biomarkers in the blood and arterial stiffness.

European dental markets trend towards group practices and consolidation Dominique Deschietere (Photo Kristine Hübner, DTI) Periodontitis linked to heart attacks in kidney disease patients Dental implant surfaces are continuously being improved to achieve better and faster integra- tion with the bone. However, a study being conducted at the Uni- versity of Cologne has found that some implants’ surfaces still ex- hibit irregularities and contami- nants, and this could have a nega- tive influence on the clinical suc- cess of the implant. Thesurfaceofanimplantsignif- icantly determines the biological response after insertion and, therefore, has a great influence on osseointegration—the successful integrationoftheimplantwiththe surrounding tissues. Different treatmentsoftheimplantmaterial during production not only affect the surface properties of the im- plant, but may also leave organic orinorganicresidueonitssurface. Researchers at the University of Cologne have analysed approx- imately 100 different implants re- garding mechanical precision and surface quality. The study, con- ducted on behalf of the Quality and Research Committee of the European Association of Dental Implantologists (BDIZ EDI), regu- larly examines the implants avail- able on the European market. The first study was launched in 2008 and analysed 23 sterile- packaged implants from nine countries. A second study with 57 implants followed in 2012. Although, according to the re- searchers, some manufacturers have made substantial improve- ments since the first examination in 2008, a recent intermediate study report showed that several implants still exhibit topographi- cal irregularities, organic contam- inants and inorganic residue from the manufacturing process. The implants were analysed under a scanning electron micro- scopeandsubjectedtoqualitative and quantitative elemental analy- ses. From these, the researchers discovered unexpected particles on some of the implants, such as chromium, copper, iron, silicon and tin, and massive organic residue, like plastic material orig- inatingfromanimplant’slow-den- sity polyethylene plastic packag- ing. There is insufficient knowl- edge about the effect of metallic particles or organic residue on sterile implants, but impurities arepreventable,explainedDrDirk Duddeck, study author and head of materials research at the Inter- disciplinary Policlinic for Oral Surgery and Implantology at the university. “It is difficult to imagine that those contaminants may have a positive influence on osseointe- gration, especially in cases with a compromised bone situation,” he stated. However, the majority of the analysed implants showed good results. “A very clean implant in thisstudywasprovidedbyPaltop. The manufacturer uses a multi- stage extensive cleaning process, which was adopted from the semi- conductor industry. This cleaning process removes undesirable residue derived from processing, yielding a contamination-free sur- face,” Duddeck said. An intermediate report of the study, titled “Quantitative and qualitative element-analysis of implant-surfaces by SEM and EDX”, was published recently in the 1/2015 issue of the European Journal for Dental Implantolo- gists.
