Destination Hamburg

Hamburg - Gateway to the world & always worth a visit

Actually, people are going as far to call Hamburg “the most beautiful city of the world”. That is for sure the slightly understating sounding self-image that Hamburgers (don’t think about food!) have of their city.

Hamburg is a cosmopolitan host, open to change, refreshing by day and exciting by night. The pulsating hub of a region which primarily stands for vastness and nature, yet also has a lot more to offer. Hanseatic Brick Gothic, grand merchant’s mansions, royal country estates and manicured parks all make up the charm of northern Germany. They attest to the civic pride in maritime traditions, economic successes, entrepreneurial spirit and typically northern German style – but certainly not stagnation.

Undergraduate Education in the UK

The majority of children in the UK access routine dental care and treatment at their General Dental Practitioners, therefore the undergraduate curriculum needs to ensure that dentists have the knowledge and abilities to manage children to the level of “safe beginner” as described by the General Dental council.

This presentation will discuss:

Current teaching of paediatric dentistry in the UK
Current expectations from graduates, regarding providing dental care to children
Current guidelines on referral to specialist paediatric dentistry services within the National Health Service

Professor Amre Shahwan is Consultant Paediatric Clinical Neurophysiologist and Epileptologist at Temple Street Children’s University Hospital, Dublin, Ireland since September 2008. After training initially in paediatric neurology, paediatric epilepsy, adult epilepsy and clinical neurophysiology (EEG) in Ireland, he specialised further in more complex paediatric EEG and complex paediatric epilepsy at the Royal Children’s Hospital in Melbourne, Australia. In his current role, he specialises in paediatric EEG, video EEG telemetry and complex paediatric epilepsy diagnosis and management. He is Honorary Associate Clinical Professor at the Royal College of Surgeons in Ireland with avid passion for teaching and education.

Epilepsy – What should we know as paediatric dentists
This presentation will address several aspects of epilepsy which paediatric dentists should be (or would like to be) aware of. There is a relatively new system for classification of seizures and epilepsy which the epilepsy community itself is only beginning to become familiar with. Old terminology is being replaced with new terminology and new abbreviations which I hope to make easy for you to remember and recognise with ease after this presentation. There are some practical aspects of epilepsy and drug therapy paediatric dentists may encounter during clinic or surgery (including significant side effects which may impact on dental health but also on dental therapies/surgeries). There are different modalities for treatment of epilepsy other than antiepileptic drugs including diets and electronic devices you may come in contact with and may have some effect-impact on certain investigations and therapies you may be carrying out. If a child has an epileptic seizure whilst in your care in clinic, are you comfortable dealing with it? Do you need to have specific measures in place where you work to be ready for such situation?
I aim to address all the above points in this presentation which is planned to demystify, clarify, inform, update and install confidence in paediatric dentistry colleagues when dealing with patients/children with epilepsy. If this summary excites you or indeed provokes certain concerns or questions in your mind, please have these ready! I will happily address these on the day.

David Manton (Netherlands)

Prof. David John Manton BDSc MDSc PhD FRACDS FICD FADI FPFA

Chair, Postgraduate Research and Education Committee
Head, Growth and Development Section

David has spent more than 30 years in private practice and academia and is currently the Elsdon Storey Chair of Child Dental Health and a visiting consultant at RCH. He is involved in several collaborative and postgraduate research projects in both paediatric dentistry and orthodontics. Graduated BDSc (Melb) in 1984 and worked in general practice until 1991 when he undertook an MDSc in Paediatric Dentistry. He was dental advisor to the Australian Federal Government from 1994 – 1996 and won the KG Sutherland Prize of the RACDS in 2007. He is on the editorial boards of the European Archives on Paediatric Dentistry and the International Journal of Paediatric Dentistry, and the advisory panel (board) of the European Caries Research Association (ORCA).

Over the past 15 years David has spoken throughout Australia, Asia and Europe and has wide ranging experience in laboratory and clinical trials of CPP-ACP, Minimum Intervention Dentistry, the definition, detection, and treatment of carious lesions, developmental defects of enamel and the use of calcium silicates in endodontics. He has published more than 100 manuscripts in peer-reviewed journals and has been cited more than 3000 times since 2014.

Summary
Developmental defects of enamel (DDE) are a prevalent condition affecting both the primary and permanent dentitions – and one of the most prevalent is MIH. A mean prevalence of around 15% has been reported for MIH, with around one third of affected teeth being affected severely. MIH affected teeth can be sensitive, suffer from post-eruptive breakdown (PEB) and have poor restorative outcomes. Therefore, repair or remineralisation of the hypomineralised lesion has the potential to ameliorate these problems. However, when trying to preserve enamel integrity, several issues can influence mineral gain of affected enamel, such as individual caries risk and compliance, lesion surface layer thickness, increased protein content and rapid PEB. Due to the high prevalence of MIH worldwide and its influence on caries risk and treatment burden, MIH presents a challenge to oral health care systems; so minimisation of treatment burden is imperative.

Learning objectives
To understand the possibility of remineralising hypomineralised enamel
To understand the limiting factors for remineralising hypomineralised enamel
To understand the methods that may improve remineralisation potential

Saving the Unsavable: Interdisciplinary treatment options for fractured, necrotic immature teeth

Prof. Dr. Gabriel Krastl

Teeth with deep subgingival tooth fractures are usually deemed non-restorable. When tooth preservation is nonetheless essential, all treatment modalities have to be considered. Surgical crown lengthening can be performed to expose the root and allow restorative treatment. However, the reduction of alveolar bone may be associated with unfavorable gingival architecture and poor aesthetic results in the anterior region.

Orthodontic extrusion (forced eruption) may be a suitable alternative to transpose the lesion to a more coronal position. Surgical extrusion, also referred to as intra-alveolar transplantation, was introduced as a faster alternative to orthodontic extrusion. Since the tooth is first extracted, deep root injuries can be diagnosed more easily compared with orthodontic extrusion. Prognosis after surgical extrusion was shown to be favourable, however the level of evidence is rather low. To minimize the risk of resorption associated with surgical extrusion, minimally invasive extraction procedures are advantageous.

Although the treatment of crown-root fractures is one of the most technically demanding procedures in dental traumatology and is frequently considered as a long-term temporary restoration, tooth conservation up to the age at which implants can be placed may be regarded as a success. However, in many cases even long-term tooth preservation of teeth with deep subgingival fractures seems feasible.

Learning Objectives

Discuss the clinical problems associated with deep subgingival margins particularly in immature teeth
Demonstrate how endodontic and restorative treatment can be carried out in difficult cases
Demonstrate the use of atraumatic extraction systems to reduce the trauma to the PDL during tooth extraction

Extraction and space management – the orthodontic solution
Extraction therapy and orthodontic space closure represent a valid treatment approach for molars affected by molar incisor hypomineralisation (MIH), which also offers certain advantages over prosthetic-restorative therapy, given favourable factors for orthodontic treatment success and a certain severity of hypomineralization with poor long-term prognosis. The decision to extract MIH-affected first molars, however, should not be made by the paediatric dentist or orthodontist alone, but always in conjunction after comprehensive interdisciplinary diagnosis and joint treatment planning, taking into account general, local and secondary factors. Extraction therapy needs to consider not only the MIH pathology itself, but the entire dental and orthodontic status of the patient in question to achieve maximum patient benefit and the individually optimal treatment with minimal adverse effects. For the success of orthodontic extraction therapy in MIH, choosing the optimal time for molar extraction (between 8 and 11.5 years of age), depending on the jaw (upper or lower) as well as the presence or absence of additional dental crowding, is essential. An early referral of children affected by MIH to the orthodontist and an orthodontic examination in the early mixed dentition is recommended to allow for correct timing of orthodontic extraction therapy and space closure in patients, which would benefit from this treatment approach. In this talk the extraction of MIH-affected molars and subsequent orthodontic space closure is discussed as possible treatment option in patients with severe MIH as well as corresponding prerequisites, timing and treatment strategy.

Bread and butter of prevention in practice
Prevention is the cornerstone of every pediatric dentistry practice. In order to enable the maximum effect of preventive measures to take place in a child, the implementation of preventive measures should start during pregnancy, whenever this is possible.
During the first years of life the responsibility of maintaining oral health lies predominantly on child’s parents/caregivers, who need to be fully aware of the importance of their role. Nevertheless, at-home care is not an independent entity, but an activity that needs to be continuously supported by professional guidance, motivation and education, as well as by professional monitoring and intervention when needed. We can expect the best at-home care to be administered by parents/caregivers that are oral health literate and eager to make every effort so that dentition in their child remains both functional and estheticaly pleasing.
In line with the evidence-based dental approach, clinical recommendations should be integrated with the individual approach to the child, with the expert judgment of the dentist, as well as with the child’s needs and preferences. It is very important to pay attention to the collection of data relating to the child’s risks (hygiene, nutrition) and needs (absence of pain and discomfort, functioning, self-esteem) as a basis for adapting preventive care to be based on individual needs.
Dentists should be motivated to build relationships with children that will encourage them to gradually take full responsibility for their own oral health and prevent disease, rather than depend on the dentist to cure problems when they occur.

Replacing the unsavable – An Interdisciplinary approach to achieve biological long-term outcomes for children and adolescents
Complex and severe trauma to the dento-alveolar structures in children can carry a life-long legacy of dental disability. Such injuries can cause irreversible damage to not only teeth, but also supporting structures such as bone making achieving long term aesthetic outcomes challenging. We have developed a multidisciplinary approach for the management of anterior teeth with poor prognosis or those that are lost as a result of dental trauma. This involves bone management at the affected site followed by autotransplantation (AT). Since the inception of this programme we have placed over 260 transplants using the multidisciplinary team comprising of both paediatric dentistry and orthodontic expertise. In this talk the speaker will aim to provide an overview of interdisciplinary treatment planning involving paediatric dentistry, orthodontics and other specialities with the goal of providing children with a long term sustainable, and biological outcome. Methods to enhance the prognosis, such as the use of surgical templates and 3D printed tooth replicas for use in surgery to reduce the damage to the PDL of the donor tooth will be discussed. The technique and clinical protocol of autotransplantation will be presented, and importantly its clinical application will be demonstrated with discussion of several clinical cases with diverse, and some complex indications to highlight the versatility of this technique. Long term outcomes of up to 15 years and prognostic indicators for successful outcome will also be highlighted.

Title:The preservation and regeneration of the traumatised dental pulp: A clinical guidance.

Abstract: Preservation of the vitality of the dental pulp is an essential component in the successful management of traumatised teeth. This is extremely important in the case of immature teeth with incomplete root formation, thin dentinal walls and compromised crown root ratios. Preservation of the pulp insures continuation of root development and hence improving the tooth’s long-term prognosis. Despite our best efforts, pulpal necrosis is one of the possible sequalae of managing traumatised teeth. In immature teeth, root canal treatment using traditional endodontic techniques lacks the potential in promoting continuation of root development. Therefore, pulpal regeneration has been hailed as the best approach in managing these cases. This lecture focus on presenting available techniques and material used in preserving and regenerating the dental pulp within the available evidence.

Objectives:

1) To discuss the available techniques and materials used in preserving the traumatised dental pulp within available evidence.

2) To discuss the evidence and available guidelines of regenerative/revitalisation endodontic technique.

Satellite Symposium in Dental Trauma – Currently accepted treatment protocols

Periodontal injuries after dental trauma – risk and consequences of ankylosis and how manage this complication

The periodontal ligament is often damaged by dental trauma. Compression, tearing, drying or storage in non-physiologic conditions are examples of this. Root resorption is often seen after serious traumatic dental injuries such as tooth avulsions and intrusions. While infection related root resorption today can be prevented or treated, ankylosis is the most serious complication resulting in progressive replacement resorption of the root by bone and eventually causing loss of the tooth. Moreover, inhibition of growth and development of the alveolar process is seen in young growing patients following ankylosis. However, also this complication can be managed today. The lecture will present how ankylosis will develop, explain its progression and consequences and how we can understand and manage such situations today. The recent shift in paradigm from “save the tooth” to “preserve the bone” will be presented.

Eija Salmela (Finland)

I have worked as a university lecturer in Pediatric Dentistry at the University of Helsinki and as a pediatric dentist at the Hospital for Children and Adolescents in Helsinki, Finland since 2012. I got specialist degree in Pediatric Dentistry in February 2019.

I finished the doctoral degree under supervision of Professor Satu Alaluusua at the University of Helsinki in 2011. During my postgraduate studies, I did in vitro research on the effects of organic environmental toxicants on hard tissue formation in developing tooth. In recent years I have participated in Professor Alaluusua’s research projects studying etiological factors of molar incisor hypomineralisation. Currently I have been working in a project concentrating in inherited diseases of dental hard tissues.

MIH and possible associations with childhood illnesses and antibiotics

Molar incisor hypomineralization (MIH) is a common condition with a worldwide prevalence reported to vary between 2.4% and 40.2%. In MIH, demarcated dental enamel hypomineralization defects are found in first permanent molars (FPMs) and frequently also in permanent incisors. The clinical severity of enamel defects ranges from small, demarcated areas with a mild change in color to large, severe lesions with post-eruptive enamel breakdown. Hypomineralized enamel lesions may cause increased treatment-need and discomfort to the patient.

The origin of MIH is systemic, but studies have shown that there might be a genetic influence as well. However, the etiology is still unclear, even though several etiological factors have been suspected. These include e.g. birth complications, common childhood illnesses, antibiotics and environmental contaminants.

Enamel of FPMs starts to mineralize around birth and the enamel formation is completed at about three years. Therefore, medical problems during the early childhood have been proposed as possible etiological factors. Several studies have reported associations between early childhood fever, respiratory disease, pneumonia, acute otitis media and MIH. There are also studies that have not found significant associations.

The use of antibiotics as an etiological factor has also been studied and significant associations have been reported in part of them. The literature is however sparse, and the level of evidence is very low. In addition, because antimicrobial drugs are used against for certain illnesses, it is difficult to determine which one, the illness itself or the antibiotic used for the illness, may have a greater impact for the risk of MIH, or is there a combined effect. In some experimental in vivo and in vitro studies, amoxicillin has disturbed enamel matrix formation and mineralization, leading to quantitative and qualitative defects in enamel. Findings from experimental studies may support the hypothesis of antibiotics as an etiologic factor for MIH, but any straightforward conclusions to humans cannot be made.

Learning Objectives:

-Even though early childhood diseases might be associated with MIH, the level of evidence is still low.

-The role of antibiotics is uncertain but possible. The literature is sparse, and the level of evidence is very low.

-It seems that the etiology of MIH is multifactorial.

-More well-designed prospective studies are needed to clarify the etiology.

What’s new in adhesive (paediatric) dentistry?
This lecture aims to provide an update on modern adhesive technology to directly restore teeth. An overview of the current state of the art regarding dental adhesive technology and their adhesion performance to enamel and dentin will be presented. The most recent generation of ‘universal’ adhesives enable the dentist to choose for either an ‘etch-and-rinse’ or ‘self-etch’ bonding approach. A next research challenge is to develop adhesive technology that additionally provides bioactivity. This can be diverse in terms of anti-microbial, anti-enzymatic and/or re-mineralization potential. Special attention will be given to potential differences in bonding to deciduous versus permanent tooth tissue, as well as some new self-adhesive restorative material developments will be addressed.

Interactions of Materials & Carious Dental Tissues
This talk will look at the intraoperative assessment and management of dental caries. The restorative dilemmas facing clinicians are more complex now than ever, as we have materials that can have a range of effects: from being simple sealers – to prevent bacterial ingress and proliferation, to bioactive materials with anti-bacterial properties and remineralising properties. Furthermore, one mustn’t forget that the pulp – dentine complex is a vital living organ and can respond by healing, with the laying down of reparative dentine, especially in the presence of therapeutic agents.

This talk will look at ways of determining the extent of dentine caries, using sound observational techniques backed up by microscopical imaging and bacteriological studies. The dynamics of the caries affected tooth complex and its interactions with materials in laboratory and clinical caries management experiments has shown that there are changes in the depths of a cavity with time. This may stall the carious process and also preserve pulp vitality.

What is new?
Discussions on the interaction of bioactive materials with caries-affected tissues.

Learning objectives

Re-evaluate how much decayed tissue needs to be removed during cavity preparation.
Appreciate the interactions between caries affected tissue and modern restorative materials.

Are endocrine disruptors responsible for hypomineralisations in human teeth?

Sylvie Babajko, director of research at the French National Institute of Health and Medical Research (INSERM)

Centre de recherche des Cordeliers – INSERM – Université de Paris – France

Our environment is considerably changing during last decades and, many recent data show the relationships between our lifestyle, exposure to multiple pollutants and development of chronic diseases. Among environmental pollutants, hundreds of them present endocrine disrupting activities, they are called endocrine disruptors (EDs). They are able to interact directly with the steroid and thyroid hormone receptors, to modulate steroid hormone synthesis and / or their circulating levels. They are thus able to disrupt the homeostasis and development of target organs, especially during fetal and perinatal life when they are particularly active. This window of time corresponds to dental development; any disturbance of amelogenesis may cause irreversible enamel defects. Molar Incisor Hypomineralisation (MIH) retained our attention because the prevalence of this enamel pathology is higher nowadays than thirty years ago suggesting an environmental causal factor, and because selective teeth are affected, permanent first molar and incisors, the first mineralizing teeth, suggesting a time-window causality. Despite its etiology is still unclear, probably multifactorial, EDs appeared as interesting enamel disruptor candidates to investigate. Our experimental results show the impact of several EDs, including bisphenol A, alone or in combination with other EDs, on the quality of enamel. The defects of rodent enamel exposed to these molecules share many structural and biochemical similarities with those of children with MIH.

We are currently progressing in characterization of the different types of hypomineralizations caused by environmental toxicants, and in ED mechanisms of actions in dental cells to demonstrate their effects. In the future, dental defects reflecting the history of exposure to toxicants could be taken into account in the follow-up of children, future adults likely to develop pathologies related to lifestyles and exposure to multiple environmental pollutants.
