The study found that this approach achieved improved re- sults compared with conventional treatments. The researchers treated 30 pre- pared flared root canals in vitro and restored these with CAD/CAM-in- tegrated glass fibre posts and cores, prefabricated fibre posts and cast gold alloy, respectively. After expo- sure to fatigue loading, each spec- imen was subjected to static loading until fracture. The findings showed that the mean fracture strengths of the teeth treated with CAD/CAM-inte- grated glass fibre posts and cores, and cast gold alloy were signifi- cantly higher than those restored with prefabricated fibre posts, whereas no differences were ob- served between the first two treat- ments. In addition, reparable fracture modes were mostly ob- served in teeth treated with CAD/ CAM-integrated glass fibre posts and cores, while irreparable and catastrophic fractures were mainly found in the other teeth. These re- sults demonstrate that, in compar- ison with conventional treatments, CAD/CAM-integrated glass fibre post and core restoration signifi- cantly enhances the fracture resis- tance of maxillary central incisors with flared root canals. The study, titled “Fracture behav- iors of maxillary central incisors with flared root canals restored with CAD/ CAM integrated glass fiber post-and- core”, was published online in Dental Materials Journal on 1 November 2018 ahead of inclusion in an issue. Nhw standard to bh dhvhlophd for sthrilh rhprochssing in dhntal practichs By DTI SYDNEY, Australia: Among the is- sues arising for small dental prac- tice owners is adhering to regula- tions that are more applicable to larger institutions such as hospitals. In what the Australian Dental As- sociation (ADA) is calling a “signif- icant advocacy win”, Standards Aus- tralia has accepted a proposal to develop a new standard for sterile reprocessing of reusable medical devices and surgical instruments. According to the ADA, it has lobbied for the past few years to prevent Australian and New Zea- land Standard (AS/NZS) 4187 from becoming the required standard applicable to small office-based practices. The new standard that will now be developed over the next several years will replace both AS/ NZS 4187 and AS/NZS 4815. The decision follows a discussion on whether there was an ongoing need to maintain two different stan- dards, given the confusion over which standard applied in which setting, or if it would be preferable to move The ADA has hailed Standards Australia’s decision to implement a new standard for sterile reprocessing in dental practices as a positive step forward. (Photograph: Okrasyuk/Shutterstock) to a single document that would meet the needs of any situation where ster- ile reprocessing is required. In response, newly elected ADA Federal President Dr Carmelo Bonanno praised the decision as an important positive step forward, noting that “AS/NZS 4187 is a stan- dard more applicable to large health care organisations and would have placed unreasonable demands on dental practices which would have resulted in increased costs for pa- tients”. It is envisaged that the single standard will be supported by a set of complementary implementation guides that will explain the appli- cation of the standard to particular settings. Throughout the develop- ment of the new standard, the ADA will remain closely involved and eventually align its own infection control guidelines to it once ready; however, until then the existing standards remain in place. A recent study found that placing a CAD/CAM-integrated glass fibre post and core decreases the risk of fracture of an endodontically treated and restored tooth.

02 ASIA PACIFIC NEWS Dental Tribune Asia Paciﬁc Edition | 12/2018 Combination of brhast milk and babihs’ saliva shaphs hhalthy oral microbiomh, study sugghsts By DTI BRISBANE, Australia: There is much debate of the pros and cons of breast- and bottle-feeding. A research team from the Queensland University of Technology (QUT), in collaboration with the University of Queensland, both in Australia, has found that breastfeeding, at least in terms of oral health of the baby, is beneficial. According to lead author Dr Emma Sweeney, from the Institute of Health and Biomedical Innova- AD tion at QUT, the team’s earlier stud- ies had found significant differences in the prevalence of key bacteria in the mouths of breastfed and for- mula-fed babies and that breastmilk and saliva interactions boost innate immunity by acting in synergy to regulate the oral microbiome of newborn babies.

A recent study conducted by the Queensland University of Technology demonstrated that breastfeeding improves the oral immune system of newborns. (Photograph: wong sze yuen/Shutterstock) For the recent study, a variety of microorganisms were exposed to breastmilk and saliva mixtures. The results showed that inhibited growth of the microorganisms took place immediately and for up to one day regardless of whether the microorganisms were considered pathogenic or commensal in an in- fant’s mouth. “Our findings suggest that breastmilk is more than a simple source of nutrition for babies be- cause it plays an important role in shaping a healthy oral microbi- ome,” said Sweeney. “Our previous research found that the interaction of neonatal saliva and breast milk releases antibacterial compounds, including hydrogen peroxide. The release of this chemical compound also activates the lactoperoxidase system, which produces additional compounds that also have anti- bacterial activity, and these com- pounds are capable of regulating the growth of microorganisms,” she added. According to the research team, the composition of a baby’s mouth microbiota has an important role in its health and well-being and also has an impact on infections and diseases in babies’ early lives. The study, titled “The effect of breastmilk and saliva combina- tions on the in vitro growth of oral pathogenic and commensal mi- croorganisms”, was published on- line in Scientific Reports on 11 Oc- tober 2018.

In a positive new development, inter- nationally renowned businessman and philanthropist, Graeme Hart and his wife Robyn have announced that they will be donating NZ$10 million towards the clinic’s con- struction. Businessman Graeme Hart and his wife Robyn have donated NZ$10 million to the University of Otago towards the construction of a new dental clinic in South Auckland. (Photograph: Cozine/Shutterstock) The University of Otago Foun- dation Trust Chair John Ward said, “this funding will make a signifi- cant contribution to the develop- ment of a new dental teaching fa- cility, which will not only provide students with diverse practical learning opportunities, but will also provide dental care for the local diverse communities at a highly accessible cost.” The NZ$28.2 million, two-sto- rey, 32-chair building will be built at the Counties Manukau District Health Board’s Super Clinic’s site. With 48 final-year dentistry stu- dents assigned to the South Auck- land clinic at any one time, the clinic will follow the long-standing social contract model that operates suc- cessfully in Dunedin, whereby pa- tients receive treatment provided by students under supervision at a very accessible cost. Hart, who lives in Auckland, was awarded an honorary Doctor of Commerce degree by the university last December in recognition of his contribution to the business sector and for his philanthropy in sup- porting education and children’s health. “We are delighted to be able to assist our university in provid- ing a dental school that will meet the needs of lower socio-economic groups. We are very pleased that the youth and young children of this region will benefit from this facility,” Hart commented. “The University of Otago re- mains highly committed to pro- viding outstanding education and to contributing to the communities where our campuses are located. The Hart family’s donation will allow us to proceed with certainty on the development of our dental teaching facility in the Counties Manukau region and it will assist us in making a substantial positive difference to the healthcare and wider wellbeing of residents of New Zealand’s largest city,” said Univer- sity of Otago Vice-Chancellor Har- lene Hayne.

04 ASIA PACIFIC NEWS Dental Tribune Asia Paciﬁc Edition | 12/2018 Survhy of Australian dhntists’ fhhs indicaths a small incrhash By DTI SYDNEY, Australia: Each year, the Australian Dental Association (ADA) conducts a dental fee survey to gain a better understanding of how pri- vate practices across the country are billing for their work. According to this year’s results, pricing has re- mained relatively stable, with only a small increase. However, as seen in previous surveys, there were sig- nificant variations in the different levels of fees that are charged, both within and between different states. The survey, conducted by ACA Research, summarises the fees charged by ADA members in private practice as at 1 July 2018. According to the ADA, there were 303 more practitioners who took part this year than last year, with a total of 1,740 valid responses received. The total participants were broken down into 1,454 general practitioners (GPs) and 286 specialist dentists. The fees charged by GPs re- mained relatively stable from 1 July 2017 to 30 June 2018 across the 121 items that were surveyed. However, there has been a continuous upward trend over the past five years. In line with the Consumer Price Index, the accumulative year-on-year in- crease in fees over the previous five years is eight per cent. Additionally, the changes in fees charged by GPs varied across all different service categories, with the highest increase in GP fees was noted for general dental services (1.6 per cent). Peri- odontics saw a decrease of 4.5 per cent; whereas preventive services and oral surgery went down 0.4 per cent and 0.3 per cent, respectively. As with previous years’ surveys, less than a quarter of GPs reported AD AEEDC 2019 05.- 07. 02. 2019 Dubai/ UAE Booth: 7F17 The annual survey by the Australian Dental Association to summarise fees charged by its private practice members has indicated that fees have increased slightly.

For the 23 per cent who do, the average rate billed was A$469 an hour, which is a four per cent in- crease from the previous A$449 an hour that was reported in 2017. On average, GPs in Western Australia charged the lowest fees, while GPs in Australia Capital Territory (ACT) and Tasmania charged the highest. The ADA did however warn that due to the small sample sizes in the ACT and Tasmania, these results should be regarded with caution. On aver- age, GPs in Victoria charged the highest mean hourly rate of A$524, while their counterparts in South Australia charged the lowest mean hourly rate of A$360. Generally, GPs in the state capitals charged a higher fee for the same item of service than GPs in the rest of the state. Approximately 11 per cent of private practice dentists in Austra- lia are specialists. From the 286 specialists surveyed in this year’s survey, 29 per cent charged an av- erage hourly rate of A$632, which increased from A$539 in the 2017 survey. Specialists in New South Wales charged the highest average hourly rate of A$684, while special- ists in South Australia charged the lowest rate of A$400. However, these results should be also be regarded with caution, due to the relatively small number of specialists included in the survey results, according to the ADA.

06 CLINICAL Dental Tribune Asia Paciﬁc Edition | 12/2018 Implants should only bh inshrthd whhn phriodontal conditions arh stablh By Dr Jan H. Koch, Germany Biofilm is the most significant cause of inflammatory bone loss around teeth and implants. Diagnostics, bio- film management and, where neces- sary, treatment help in patients with this problem. The W&H No Implan- tology without Periodontology work- flow should provide stable tissue prior to implantation through prevention, and implant success in the long term through aftercare – something that is advantageous to both the patient and the treatment team. Implant treatment can signifi- cantly improve quality of life after tooth loss.1, 2 The long-term prog- nosis is generally good, but biolog- ical complications are common.3 Peri-implantitis and its preliminary stage, mucositis, occur in a substan- tial proportion of patients.4 As is the case for periodontitis and gin- givitis, oral biofilm is the main cause.5, 6 This microbial biocoenosis can also encourage the develop- ment of severe systemic disease in the event of pathological changes, such as endocarditis and inflam- matory bowel disease.7 The only difference in the mi- crobial flora in periodontitis and peri-implantitis is in the detail.8 Compared with healthy conditions, the quantity and aggressiveness of the pathogenic microorganisms change in both diseases.5, 6 Bone loss around implants is generally more rapid and leads to more ex- tensive defects than when it occurs around teeth.9 Accordingly, pre- ventative care is advised even be- fore implant treatment. This means untreated periodonti- tis patients have an increased risk of peri-implant inf lammation through to implant loss.10 The risk is also higher when patients who are initially treated are not included in a supportive periodontitis treat- ment/recall programme.11 Leading periodontists there- fore recommend carrying out a screening procedure before im- plant treatment using, for exam- ple, the periodontal screening index or periodontal screening and re- cording.12 Bleeding on probing and pocket depths are determined at selected positions. An extensive check of the periodontal status should be carried out if the results are abnormal.13 Taking a careful medical his- tory, including previous systemic exposure, is also important.13 This provides important information about increased risk of inflamma- tion, for example in patients with diabetes that is not being optimally managed.14 Furthermore, patients should be informed of the risks relating to implants. Where necessary, initial peri- odontal treatment is carried out. First, professional tooth cleaning establishes healthy gingival condi- tions. In this procedure, calculus (Fig. 1) and biofilm (Fig. 2) are re- moved as far as the gingival sulcus. In combination with careful in- struction on oral hygiene, this gives the patient the basis for long-term freedom from inflammation.15 Determining risks and providing periodontal treatment Periodontitis is a key risk fac- tor for peri-implant inflammation. Removal of subgingival coat- ings (debridement) is carried out using sonic or ultrasonic devices and special periodontal tips as ini- tial periodontal treatment (Fig. 3). Manual instruments can also be used. Further surgical and/or re- generative measures may be nec- essary, depending on the situation. Periodontal aftercare for long-term success In the periodontal aftercare subsequent to implantation, soft (biofilm) and hard coatings are regularly professionally and me- chanically removed.16, 17 In the sub- gingival and supragingival areas, ultrasonic devices are generally used for this (Fig. 4), in combina- tion with manual instruments where necessary. Alternatively, subgingival air polishing can be used in combination with peri- odontal attachments and powders.18 Checking for individual risk factors, such as smoking and dia- betes, and working towards a healthy lifestyle are also recommended for a good long-term prognosis after periodontitis treatment.13, 19 If the patient had severe periodontitis before the initial treatment, the re- call frequency will be increased ac- cordingly, partially to prevent peri-implant inflammation.20 Proactive implant treatment If the patient has received good preventative treatment and where necessary has received prelimi- nary periodontal treatment, im- plant treatment can be planned. A suboptimal implant-supported prosthesis increases the likelihood of biofilm forming.21 In order to avoid this, the correct implant po- sition, sufficient distances from adjacent teeth and an ideal axial alignment should be considered during the planning phase. A suf- ficiently sized bone site and soft tissue that is well supplied with blood are needed for successful implant healing and a good long- term prognosis. Prior or simulta- neous augmentation may be needed to achieve this. In contrast to this, the time at which the implant is inserted and the treatment is pro- vided plays a less significant role.22, 23 In order to support predictable and stable implant treatment, it is also necessary to prepare the im- plant bed using suitable methods and equipment. This can be achieved using high-performance implan- tology motors in combination with surgical contra-angle handpieces. Using a low speed and an ample supply of sterile cooling fluid is es- sential during preparation.24 Oth- erwise, the bone can overheat and affect the healing process. Alternatively, the implant bed can be prepared with piezo-surgi- cal systems, for which special sets of instruments are available.25 Bone can be worked on in a gentle yet highly effective manner using other special instruments. Indications include alveolar ridge splitting, sur- gical tooth removal, and the prepa- ration of bone blocks or lateral win- dows for augmentation.26 Highly advanced piezo-surgical devices are also minimally invasive in soft tissue. Stability measurement and bone surgery Once the implant has been screwed into its final position, the primary stability can be safely and precisely determined using reso- nance frequency analysis. The tech- nology is available either separately or as an optional module in an im- plantology motor. If the ISQ (Im- plant Stability Quotient) value mea- sured is 66 or higher, early inter- vention is possible, and if it is over 70, treatment must be provided immediately.27 An exposure protocol based on the ISQ value improves the prog- nosis of treatment. Simply mea- suring the torque resistance, how- ever, does not provide the same level of clinical safety.28 If reduced ISQ values are measured after the implant has been inserted, a two- phase protocol is generally chosen. After exposure, a new measure- ment can then be used to deter- mine whether osseointegration has been successful (secondary stability) and loading will be pre- dictable at this point.29 Hygiene-friendly prostheses The emergence region should be designed to ensure that it is at- raumatic to the tissue for long-last- ing implant restorations. The im- plant–abutment connection, ma- terial, surface and emergence pro- file must be biocompatible and mechanically resilient over the long term. The transgingival com- ponents should also be accessible for individual and professional cleaning and for probing.20 Definitively integrating abut- ments or other components at im- plant level immediately (“one abut- ment, one time”) has also proved to be effective.30 In combination with good hygiene and correspond- ingly healthy tissue, this concept can probably be used to achieve a more stable attachment of the im- plant to the oral cavity than if the components have to be replaced several times - a requirement for peri-implant health. 1 3 2 4 5 Fig. 1: Calculus removal using an ultrasound (W&H Tigon (+) with a 3U tip) is a key part of professional tooth cleaning.

Dental Tribune Asia Paciﬁc Edition | 12/2018 CLINICAL 07 Whether it is with crowns, bridges, partial or complete pros- theses, the implant-supported su- perstructure should be designed so that the patient can maintain it without any difficulty.20 Addi- tionally, a distance of at least 2 mm between the bone and the mucosal edge of the prosthesis appears to be advised to prevent infection and subsequent bone loss.31 Peri-implant aftercare Experts recommend treatment immediately after the initial occur- rence of symptoms of inflamma- tion to avoid peri-implant bone loss from the start.20 Mucositis affects almost half of all implants, and since patients often have several implants, it occurs in a high per- centage of patients.32 The prophy- lactic or periodontal recall pro- gramme established after the im- plant has been inserted should therefore be continued.20, 33 At-home oral hygiene should be carefully tailored to the new prosthesis and the patient accordingly instructed on this.34 In combination with pro- fessional biofilm management, good preventative efficacy can be achieved in this way.35 The risk of peri-implantitis de- creases from 43.9 per cent (no recall) to 18.0 per cent if a patient receives a recall appointment carried out carefully each year, in other words by more than half.36 Ultrasonic sys- tems with special instruments that do not affect the materials are suit- able for this, such as those made of PEEK (Fig. 5), or appropriate manual instruments.37 Mechanically preventing mucositis As for periodontitis patients, peri-implant recall includes regular screening with a clinical check of both periodontal and peri-implant tissue for symptoms of inflamma- tion, probing and, where necessary, radiographic diagnosis.9 A frequency of two to four times a year has proved to be effective.17 Deep probing val- ues and bleeding occur more com- monly in patients with peri-implan- titis than in those with mucositis; pus secretion only occurs in patients with peri-implantitis.38 If a patient has mucositis, pro- fessional supragingival and sub- gingival biofilm removal reduce the risk of the inflammation ad- vancing to peri-implantitis. Local and systemic antibiotics used as supportive measures or air polish- ing, however, show no additional benefit.20, 39 Treating peri-implantitis Peri-implant bone loss can de- velop even if good preventative care is provided, for example if the patient’s oral hygiene is not sufficient. Most minimal defects should be treated in a non-surgi- cal manner using peri-implant debridement. 37 Mechanical re- moval of coatings using suitable ultrasonic systems, supported by Er:YAG lasers, antibacterial pho- todynamic treatment, air polish- ing, or treatment with local or systemic antibiotics, where appro- priate, has shown promising re- sults.37 If closed treatment is no longer possible, the defect must be surgi- cally exposed and carefully decon- taminated. This is carried out after flap preparation by removing in- flamed tissue and cleaning the sur- face of the implant using, for ex- ample, ultrasonic or piezo-surgical systems. Measures designed to re- generate the bone carried out after this procedure have been success- ful.40 Special piezosurgical instru- ments are available for the surgical treatment of periodontal defects. After treatment, the patient is once again intensively instructed on oral hygiene and made aware of the need for continual recall. If necessary, the frequency can be selected to be higher than previ- ously in line with periodontal after- care. If biofilm management is carried out consistently, the implan- tological results can remain stable for several years even after the peri- odontitis, mucositis or peri-implan- titis has healed.33, 39 No Implantology without Periodon- tology Successful implant treatment requires consistent, long-term pre- ventative thinking. In each phase, this includes regular periodontal and peri-implant screening in com- bination with individually tailored risk management, oral hygiene training and professional biofilm management where possible for every patient. Ideally, this preventative work- flow should start well before each restorative measure, before peri- odontitis can develop. It is essential if implant prosthetic treatment is planned or has already been inte- grated. Patients will be pleased with the long-term success of the treat- ment and will be pleased to return to a practice or clinic they trust.

08 WORLD NEWS Dental Tribune Asia Paciﬁc Edition | 12/2018 BDA warns against rhstricting dhntal visits to onch hvhry two yhars By Dental Tribune UK STIRLING, UK: A recent survey con- ducted by the British Dental Asso- ciation (BDA) has found that a Scottish government initiative to potentially extend the time be- tween dental appointments to 24 months has caused concern among Scottish dentists regarding possible delayed diagnosis of oral cancer. Earlier this year, the Scottish government launched the Oral Health Improvement Plan, which AD BDA Scotland has cautioned against attending dental check-ups only once every two years, as it may neg- atively impact the ability of dentists to detect oral cancers at an early stage. (Photograph: Andrey_Popov/ Shutterstock) outlines, among other things, a fo- cus on improving prevention, re- ducing oral health inequalities, and meeting the needs of an ageing population. Though the BDA wel- comed these ambitions, it expressed dismay that the plan recommends that certain patients with good oral health should only attend dental check-ups once every two years. A subsequent BDA survey of Scottish dentists found that 97 per cent of respondents are concerned that these extensions of recall intervals could undermine the detection of oral cancers, which 77 per cent re- garded as a major or severe risk. Scotland has seen a 37 per cent increase in oral cancer deaths over the past decade, and incidence rates are among the highest in Europe. Though it is primarily caused by smoking, excessive alcohol con- sumption and human papilloma- virus infections, oral cancer can also occur in individuals leading generally healthy lifestyles. Given that survival rates for oral cancer improve f rom 50 per cent to 90 per cent with early detection, regular check-ups are essential. Dr David Cross, Vice Chair of the BDA’s Scottish Council, said: “Den- tists are on the front line of a battle against some the fastest rising can- cers in Scotland. Early detection is key, but now risks becoming a casu- alty of a cost-cutting exercise.” “People in otherwise good health are succumbing to this disease. Tell- ing our ‘lower risk’ patients to come back in two years will only handicap efforts to meet a growing threat, while putting further pressure on NHS cancer services,” he continued. “Oral cancer now claims three times as many lives in Scotland as car accidents. Rather than chasing quick savings we need to see con- crete plans and real investment to help turn the tables on this devas- tating but preventable disease,” Cross advised.

The study also established that previous visits to the dentist, as well as parental back- ground and level of education, af- fect how children experience the loss of their first tooth. Children generally lose their first primary tooth when they are about 6 years old. This gradual process is probably one of the first biological changes to their own bodies that children experience consciously. The emotions that accompany this milestone are extremely varied, ranging from joy at having finally joined the world of grown-ups to fear about the loss of a body part. An interdisciplinary team of re- searchers at UZH, in cooperation with the City of Zurich’s school den- tal services, has examined the feel- ings that children experience when they lose their first primary tooth and what factors play a role. The sci- entists surveyed parents of children who had already lost at least one of their primary teeth. Of the nearly 1,300 responses received, around 80 per cent of parents reported pos- itive feelings, while only 20 per cent told of negative emotions. The researchers found that pre- vious visits to the dentist played a role regarding children’s feelings. Those whose previous visits were cavity-related and thus perhaps as- sociated with shame or guilt expe- rienced fewer positive emotions when they lost their first primary tooth. If, however, previous dental appointments were the result of an accident, and thus an abrupt, un- expected and painful event, the loss of the first primary tooth was more likely to be associated with positive emotions. According to lead author Dr Raphael Patcas, from the Clinic of Orthodontics and Pe- diatric Dentistry, one possible ex- planation for this is that primary teeth loosen gradually before fall- ing out—a process that, unlike an accident, unfolds slowly and pre- dictably. This is also supported by the finding that children who ex- perience the loosening of a tooth over an extended period tend to have more positive feelings. The longer the preparation and waiting time, the greater the relief and pride when the tooth finally falls out. Moreover, the study found that socio-demographic factors are re- lated to children’s feelings. For ex- ample, children were more likely to have positive feelings such as pride or joy if their parents had a higher level of education and came from non-Western countries. The re- searchers indicate that cultural dif- ferences could be at play here. These include education style and norms that parents pass on to their chil- Researchers from the University of Zurich have found that children mostly experience the loss of their first primary tooth as something positive.

This find- ing is important for dentists and parents alike: “Especially where cavities are concerned, it’s worth communicating with children pru- dently,” added Daum. “This way, emotions in connection with teeth and dentists can be put on the most positive trajectory possible.” The study, titled “Emotions ex- perienced during the shedding of the first primary tooth”, was pub- lished online on 15 September 2018 in the International Journal of Pae- diatric Dentistry ahead of inclusion in an issue. Nhw study links poor tooth- brushing habits to hhart dishash By DTI New research suggests that brushing one’s teeth less than twice a day for less than 2 minutes at a time may lead to a threefold increase in risk of developing cardiovascular disease. (Photograph: Aleksandr Lupin/ Shutterstock) CHICAGO, US/LONDON, UK: A new study presented during the 2018 American Heart Association Scien- tific Sessions held recently has sug- gested that brushing one’s teeth at least twice a day for at least 2 min- utes may reduce one’s risk of devel- oping cardiovascular disease. In response, the Oral Health Foundation, a leading charity work- ing to combat oral disease in the UK, stressed the importance of tak- ing charge of one’s oral health, stat- ing that it can provide benefits that go far beyond the mouth. “Findings like this may sound slightly scary to hear but it could prove to be just the push we need to take better care of our oral health,” said Dr Nigel Carter, OBE, CEO of the Oral Health Foundation. “This study adds to the growing scientific evidence that this is a strong link between the health of our mouth and that of our body.” “For many years, gum disease has been linked with conditions like strokes, diabetes, dementia, and pregnancy outcomes. These are all serious conditions that could im- pact on a person’s quality of life,” he continued. “Looking after our mouth should be a priority every day and the ben- efits of doing so are simply too im- portant to ignore,” Carter said.

(Photograph: Hu-Friedy/WeRestore.it) Until now, the minimum num- ber of instruments in a kit was five, and with an array of instruments on the market, it has become increas- ingly difficult for practitioners to make the right choices. Aiming to create something more compact, es- sential and easy to use, the creators of the 3SSENTIAL KIT settled on just three instruments: Anterior (red), Posterior (blue) and Spatula (grey). Speaking about the new kit, Sco- lavino said: “The concept behind the Posterior is very simple: we wanted to go from a plug-and-play to a plug- and-sculpt method. One tip is used to plug the composite into the cavity and the other one can sculpt and model composite in additive and subtractive modelling techniques”. According to Paolone and Scolavino, the Anterior is referred to as a solid brush, since it models and spreads the composite just like a brush. Giana Spasic, Manager of Key Opinion Leaders Strategy at Hu- Friedy, said the company is always looking to work with key opinion leaders, specialists, private practi- tioners, universities and educators, with the purpose of finding new ways to help clinicians to perform at their best. The creators believe the kit is the most straightforward restorative kit ever made and is perfect for clini- cians who want to save precious time in the dental office during restorative procedures and achieve remarkable aesthetic and functional results.
