Biography:
Thomas H Loew is doing clinical research in relaxation exercises since 1992. As a psychiatrist and specialist in Psychosomatic Medicine and Psychoanalyst he works on the transfer of simple physiologically founded interventions into general medicine, e.g. hypertension, asthma, headache, somatoform disorders, obesity and specific phobias, for example dental anxiety. He is the President of the German Association for Medical Relaxation Methods, Hypnosis, Autogenic Training and Therapy and VicePresident of the Association of European Physicians for Psychosomatic Medicine.
Abstract:
Introduction: Slow paced breathing (SPB) for some minutes has relevant effects on high blood pressure it improves heart performance, relaxes and reduces anxiety. To get the right rhythm devices like Respirate®, Decelerbreather®, Atemtakter® or some apps (e.g. Breathe) are used. Clinical relevant effects are shown already after 3 minutes, two times a day. 3 minutes, two times a day? - The time we use for tooth brushing. So why not get double efficacy? A hydrodynamic sonic toothbrush (HST) can provide acoustic information. The Edel White HST includes a Yoga-Modus: It proposes a rhythm from the Pranayama tradition: After 4 seconds breathing in, the air is hold for 4 seconds followed by 8 seconds expiration.
Method: In a controlled randomized trial of cross over design with 20 participants and the effect of this “Yoga-Modus” was compared to standard HST, HST combined with an external breath pacer device in the other hand providing the usual SPB (4 seconds inspiration, 6 seconds expiration) and a combination with a body-oriented technique practiced while brushing. Blood pressure was measured with a wrist monitor before and after brushing.
Results: There was a significant reduction of blood pressure observed for standard HST and the Yoga-Modus. But not everybody took profit from the hemodynamic point of view from the standard HST only 10 out of 20 reduced their blood pressure while brushing the teeth. Further 8 participants could profit from the Yoga-Modus. Introducing a respiration regime in a hydrodynamic sonic toothbrush has a helpful physiological impact on blood pressure regulation.

Keynote: Soft tissue expanders behavior, in vitro pilot study of swelling speed and future perspectives
Biography:
Jose Luis Latorre Valenzuela specialized in Implant Dentistry in Barcelona at International University of Catalonia, UIC. He was interested in soft tissue management and continued his education with the Postgraduate program in Periodontics at UIC. Nowadays, he combines his practice focused on Implant Dentistry, Periodontics, Implant prosthesis with the research activity, at UIC.
Abstract:
Aim: The aim of this study was to analyze the swelling speed of tissue expanders.
Materials and Methods: Six samples of Osmed® soft tissue expanders were studied in vitro. They were submerged in saline solution CL Na 0.9% 37°C, imitating human conditions. The samples were weighed every 24 hours for the first 2 days; therefore, every 4 days until the samples stopped absorbing fluid. The weight measurements gave us the swelling speed of the devices in these conditions.
Results: In this in vitro study, the curves expressed by the expansion behavior of Osmed® devices are described.
Conclusion: The swelling behavior of Osmed® soft tissue expanders demonstrated in this vitro study, could differ from a linear growth. There are differences in behavior between the two devices studied. Swelling speed should be considered when applying soft tissue expansion devices, prior to any regenerative technique.

Abstract:
Dental implants have changed the face of dentistry over the past 30 years. This extensive, permanent procedure is used to treat people with terminal dentition, dental aversion and for cosmetics; it is both a functional and aesthetic procedure. Other invasive and permanent procedures such as gastric bypass and cosmetic plastic surgery rely on a psychiatric evaluation prior to surgery to either rule out inappropriate candidates or develop a plan for management. However, research suggests that this is not a common practice among oral surgeons and dentists. Failure to screen for psychiatric illnesses leaves the dentist and the patient vulnerable to a myriad of potential time consuming and costly problems. It is not always evident initially that a person may be inappropriate for implants and being able to identify warning signs early is essential because once the surgical process has started, it is a long-term commitment that is extremely difficult or impossible to reverse. The purpose of this presentation is to increase awareness of the unique needs, not only of the patients, but also the provider. Understanding the impact that patients with mental illness have on a practice is important and care must be taken to determine if implant procedures are appropriate. This presentation will center around four psychiatric disorders particularly relevant to aesthetic dentistry. They are: dental phobia; posttraumatic stress disorder; obsessive-compulsive disorder and; body dysmorphic disorder. Suggestions for screening prior to surgery will be also discussed. It is important to note that these illnesses are not obstacles for every patient who experiences them, but good practice warrants an understanding of these disorders for the development of a positive approach to treatment.

Abstract:
For many years, we have used regenerative endodontics procedure (REPs) in immature teeth with necrotic pulps and the results were impeccable as the clinical signs and symptoms were eliminated in addition to thickening of the canal walls or continued root development however the question or debate still remains whether we can used it also in mature teeth with necrotic pulp as an alternative to other kind of treatments, there has been many cases that used the (REPs) with a very promising results rendering REPs suitable treatment in some cases. REPs can repair or renovate the vitality of tissue in the canals of immature or mature permanent teeth previously destroyed by infection or trauma. The induction of periapical bleeding into the disinfected canal of immature or mature permanent teeth during REPs brings mesenchymal stem cells and likely growth factors (platelet-derived growth factor, platelet-derived endothelial growth factor, transforming growth factor and insulin like growth factor) mainly derived from platelets as well as fibrin scaffold from the periapical tissues into the canal space. The stem cells capable of producing mineralized tissue have migrated into the canals and formed hard tissue on the canal walls and at the root apex. Therefore, it is likely that new vital tissue might also be able to generate in the canals of human mature permanent teeth with necrotic pulps after REPs. REPs may become a feasible treatment for mature permanent teeth with infected or non-infected necrotic pulps which indicate that we still have not discovered all the possibilities of steam cells that should be taken in consideration.
Elena Rodriguez
University of Oviedo, Spain
Title: Timing in orthodontics: A simple guide for the general practitioner
Biography:
Elena Rodriguez is pursuing her Postgraduate Program in orthodontics at University of Oviedo.
Abstract:
Thousands of children visit the dentist every year and even though the general practitioners do their best to provide them with a good oral health, there is always something that escapes our control, the way teeth and jaws are disposed. According to research carried out in the UK almost 55% of the children population has an orthodontic problem. So, how do the general dentists know when it's the right time to refer these patients for their ï¬rst appointment with orthodontist? Specialist's opinions differ on the matter of the right time to see the potential patients for their ï¬rst time. These treatments are very time sensitive and if they're premature or delayed it leads to problems down the line which could have been prevented. The purpose of this study is to provide the general practitioner with the necessary tools and tricks to identify the most common malocclusions in the dental practice and to give them the ability to decide when is the perfect moment to start with our treatment based on age, development and the jaw problem.

Abstract:
One of the important drawbacks of commercially used orthodontic aligner is the change regime (14 days) due to the ratelimiting step. Therefore, investigators are working on doing improvements to aligner materials, force systems, staging of tooth movements, and treatment planning. One of these trails is the incorporation of shape memory polymers (SMPs), a type of important stimuli-responsive smart polymers, which can recover their original shape upon exposure to external stimuli. The purpose of this presentation is showing how far our research is going regarding producing an active orthodontic aligner made up of shape memory polymer, through a 3D finite element simulation model and experimental testing.

Abstract:
In the book “Seeing what’s next,” Clayton Christensen coined the term disruptive innovation and further predicts the future of different industries. Disruptive innovation may be defined as an innovation that disrupts an existing market by taking out a service or product in that market and entering it into a new or another existing market. As a result, this decreases the value of one market while increasing value of another. After examining various case studies, it was determined that Clayton Christensen disruptive innovation model may be applied to predict the future of dentistry. An infographic was created to illustrate this notion. Education differentiates the level of the hierarchy, while the area of each segment represents market size available for that section. With time, it is natural for services to decrease sectors. In the current day, you will find general dental practitioner offices that offer more services outside the general dentist scope. Practitioners have access to continuing education courses allowing them to be trained in areas of specialty, such as Invisalign. There is an increased prevalence of general dental practitioner offices offering services for extractions and implants, rather than referring a patient out. The general dentist can perform the operation if they believe they can perform up to the standard of a specialist. If not, the dentist may hire a specialist to come into the office and carry out the surgery in-house. This scenario will happen for an array of reasons. Research contributes to each disruptive innovation through finding new biological treatments, such as natural adult tooth growth with the contribution of laser stimulation, the addition of fluoride in public water, and the implementation of technology to aid treatment. This is important in dentistry to continuously enhance the care that a health care provider can give to patients.

Title: Audit: Improve the turnover for the reporting time for oral biopsies
Biography:
Manpreet K Gakhal qualified from Queen Mary, University of London in 2015. Following this, she has successfully completed her vocational training, and two years of Dental Core Training years 1 and 2 in Oral & Maxillofacial Surgery and General Practice & Special care Dentistry respectively. She is currently working as a Clinical Fellow in Pediatric Dentistry. She has also completed Diploma of Membership of the Faculty of Dental Surgery (MFDS) at Royal College of Surgeons of Edinburgh.
Abstract:
Aim: To increase the turnover of reporting times of oral biopsies.
Objectives: 1. Identifying the proportion of oral biopsies that being reported within in the recommended guidelines. 2. Identify the proportion of oral biopsies that are not being reported within the recommended guidelines. 3. Identify the proportion of oral biopsies that are urgent and no urgent.
Standards: The Royal College of Pathology
Suspected mucosal malignancies - 80% of diagnostic biopsies will be reported within seven calendar days of the biopsy being taken. 80% of all the histopathology specimens (excluding those requiring decalcification) will be reported within 10 calendar days of the specimen being taken.
Non-urgent mucosal malignancies - Histopathology cases reported, confirmed and authorized within 7-10 calendar days of the procedure. Standard 80% of cases must be reported within seven calendar days and 90% within 10 calendar days. Methodology: Data was collected both retrospectively from 369 patients by liaising with the Pathology Department, at Queens Medical Centre, from patients who had intra-oral biopsies taken under both local and general anesthetic.
Results: Cycle 1 The results show that only 18% of oral biopsies were reported within the recommended guidelines.
Implement change: This issue was raised at a departmental study day, and the concerns were addressed from all members of the team. The departmental consultants for maxillofacial and restorative had liased with pathology consultant regarding the results. It was established that the pathology department was experiencing a significant backlog and therefore it was proven difficult to ensure that all departmental biopsy results were returned within the recommended guidelines.

She has held many positions in UAE. Currently, she is working as an Endodontist at health point.
Abstract:
Endodontics is the clinical management of a microbiological problem. The aim of root canal treatment is to eliminate bacteria from the infected root canal and to prevent reinfection. Although, biomechanical cleaning and shaping of the root canal greatly reduces the number of bacteria; in necrotic infected canals, the reduction in bacteria is challenging. The microbes extend into the dentinal tubules where instruments do not reach. In addition, the anatomical complexity of the root canal system prevents complete removal of the organic and inorganic residues and bacteria. Microbes thus persist and directly affect the clinical outcomes of endodontic treatment. Shaping is not equal to cleaning. The microbes in the dentinal tubules are the source of recontamination after endodontic treatment. The strategy is to focus on the factor that determines the success of endodontic treatment: Disinfection. Irrigation plays a key role in disinfection. The past decade has various studies on the effectiveness of various irrigating solutions available and developed in the market. But considering the vapor lock effect and the tenacity of biofilms to change their phenotypes, Walton and Torabinajed have so aptly put forth a vital question- "Is good disinfection related to irrigating solutions or Irrigating systems?" This Presentation will endeavor to discuss the importance of infection control to increase endodontic outcomes, and review all the classic and contemporary techniques, instruments and materials to achieve predictable and safe disinfection.

Title: Dental management of patient with epidermolysis bullosa: A case report
Biography:
Ahmed A Albariqi is currently pursuing his PhD in Paediatric Dentistry at School of Dentistry, University of Leeds.
Abstract:
Introduction: Epidermolysis bullosa is a series of skin disorders characterized by blistering and mechanical fragility of the skin, including the oral mucosa and digestive system lining. Because of its low prevalence, many dentists have limited knowledge of the disease. The scientific literature regarding oral health care of people living with EB is relatively scarce. This makes it difficult for dentists with no experience in treating people with EB to know how to approach them in a safe manner given all the special care these patients might need. DEBRA International entrusted the development of Clinical Guidelines to health care professionals with significant experience in EB around the world. These guidelines contain the appropriate precautions that people with EB might require to receive optimal oral health care. The present guidelines on dental care for people living with EB have been developed by an international team of dentists, using a standard methodology based on a systematic review of the currently available scientific evidence. These guidelines can be applied to all patients diagnosed with epidermolysis bullosa. As such, the guideline considers information for all four major types of EB: EB simplex, junctional EB, dystrophic EB, and Kindler syndrome.
Background: A 6-year old girl presented to the Leeds Dental Institute (LDI) for dental treatment.
Case Report: Clinical and radiographic examination revealed that she has dental caries affecting both anterior and posterior teeth, early mixed dentition, class 1 malocclusion, and poor oral hygiene. Detailed medical and dental history was obtained from medical consultants and parents. Clinical report of her medical condition was provided by her medical team confirmed she has Dominant Dystrophic EB. Liaison with medical team supervised her case were made to check if there are any special precautions or investigations that need to be undertaken pre, peri and postoperatively in patient’s care. Comprehensive treatment including prevention, restorations of anterior teeth 52, 62, and 73 were carried out using composite resin restorations. Extraction of badly decayed teeth 55, 54, 64, 65, 74 and 84 and all the treatment modifications and precautions were used based on oral health care for patients with epidermolysis bullosa guideline published by DEBRA.
Follow-up: She was followed up for 6 months after initial presentation and both parents and patient were satisfied with the outcome.
Conclusion: Epidermolysis bullosa is a rare disease with multiple oral manifestations, which requires a special approach from the dental point of view. It is important that dental practitioners who treat patients with EB know how to best manage their care. This research presentation reviews the major causes and manifestations of EB, discusses a unique case study of how dental treatment was rendered to a patient with the condition, and suggests ways to properly manage the oral health needs of patients with EB and similar disorders.

Title: Comparison of patient satisfaction treated with fixed and removable implant prostheses in severely bone resorption using a visual analog scale
Biography:
Isil Damla Sener Yamaner has completed her PhD in the Department of Prosthodontics, Faculty of Dentistry at Marmara University and Postdoctoral Studies in the Department of Prosthodontics, Faculty of Dentistry at Istanbul Aydin University. Currently, she is an Assistant Professor and has published about 25 papers in reputed journals.
Abstract:
Bone resorption in dental arch can occur due to early tooth loss, periodontal problems, tumor resection, trauma etc. Patients with severe bone resorption usually experience severe retention and stability problems with their denture. These patients have the greatest need for implant prostheses but also present with findings that make management more complex. There are several prosthetic options to treat severely resorbed edentulous jaws. One of them is the placement of two or four implants between the mental foramens and rehabilitation of the patients with bar or ball splinted removable prostheses. Bar or ball splinted overdenture prostheses may offer significantly enhanced bite force, chewing efficiency and oral health compared to conventional complete dentures. However, patients may find removability less attractive. Other option is fixed-detachable hybrid implant prostheses which are cantilevered restorations. It is screwed onto premaxillary or interforaminal five or six implants to provide an acceptable esthetic, phonetic and functional result. This treatment option also helps patients with large maxillofacial defects by enhancing denture retention and stability. This presentation compared patient satisfaction levels in patients treated with fixed or removable implant prosthesis in case of extremely bone loss according to patient; comfort, esthetic and phonetic. A total of 22 patients assigned scores for their satisfaction after treatment regarding chewing, esthetics, comfort and phonetics. The average visual analog scale (VAS) scores regarding chewing and comfort were higher in patients treated with fixed implant prostheses than removable ones. However, VAS scores related to esthetic and phonetics in patients treated with removable implant prostheses were higher than fixed prosthesis.

Abstract:
The interrelationship of restorative dentistry and periodontics is dynamic. Using these basic guidelines, restorative care can be used to directly aid periodontal treatment by restoring an esthetically pleasing, comfortable and stable dentition. The clinician strives to create a beautiful smile paying attention not only to the glimmering white teeth, but also to the health of the surrounding tissues. A sound periodontium provides a firm foundation for an esthetic and functional prosthesis. Conversely, when restorations are designed to be self-cleansing and promote gingival health, the tissues present a harmonious esthetic blend at the restorative-gingival interface. This involves incorporating a comprehensive treatment plan, paying close attention to both soft and hard tissues around teeth and implants before, during and after restorative procedure. Key aspects of the restoration design that have a direct effect on the periodontium include restoration contour, margin adaptation, margin placement, prosthetic and restorative materials, design of fixed partial dentures, restorative procedures and occlusal function. Special emphasis is paid to the consequences of violation of biologic width that leads to inflammation, possible recession and unsightly exposure of crown margin. Periodontal considerations include control of periodontal inflammation, correction of the gingival architecture, and periodontal maintenance. This literature review was addressing the interactions between periodontal tissues and restorative procedures.

Abstract:
Statement of the Problem: As social media has become such a pervasive part of our lives, we as dentists and dental educators should work on the positive impact that social media has on the society and dental students. This study was based on the available literature studying the fact that due to the emergence of Web2, dental practitioners notice the importance of building a new kind of relationship with their patients using the communicative language used in social media and building a bond of loyalty and trust that makes this tool the most important in build a great reputation and higher number of followers and hence a successful practice. How to apply these finding on a sample taken from the authors main social media platform and discussing some striking feedbacks from the followers might give a new wider vision to help advance your social platform to the maximum advantage. Apart from the importance of the social media on education, your platform as an educator and or dental service provider can be considered now days the main patient source.

Ashish Patel is in his second year of dental core training in an Oral & Maxillofacial department, having graduated from King’s College London and has interest in oral surgery.
Abstract:
A hole in the mouth: A presentation of a case of a 32-year-old male who first presented to the Emergency Department at Southampton General Hospital, United Kingdom with a ‘hole’ in his mouth. The patient underwent various investigations during his clinic visits and multiple biopsies were required to confirm a diagnosis. Results initially suggested a benign selflifting condition, necrotizing sialomaetaplasia, for which the management would have been conservative only. However, due to clinical instinct, further biopsies revealed the presence of a Squamous Cell Carcinoma (SCC). This case is of significance for several reasons; firstly, the literature suggests that necrotizing sialometaplasia is a benign condition that can often mimic features of SCC, however there are fewer instances in which an SCC mimics a necrotizing sialometaplasia. Above all, this case highlights the importance of a clinical examination and a clinician’s ‘gut’ instinct and how this remains the most important aspect of an examination. Far too often do we rely on biopsy results for a diagnosis, however in this instance it was clinical judgement that was fundamental to differentiating an SCC from necrotizing sialometaplasia. This case can act as learning point for all clinicians in all fields of dentistry from junior trainee level up to consultant level.

Title: Assessment of the efficacy of thermography for the detection of artificially induced fractures in teeth: An in vitro study
Biography:
Shimpi Manasi Rajendra is currently pursuing her Master’s in Pediatric and Preventive Dentistry in India. She endeavours to improve oral health and the overall well-being of individuals, especially children. Using non-invasive techniques, through dedicated research and expertise in clinical practice, she aims to work towards the prevention of dental diseases in the paediatric population. She is currently conducting intense research in the various applications of Thermography in Dentistry.
Abstract:
Statement of the Problem: Most clinicians find it difficult to diagnose vertical teeth fractures due to the complicated and diverse symptoms that vary according to the position and extent of the fracture. Current methods such as radiography, transillumination, use of dyes, and operative microscopic examination have limitations, and the use of dental radiography or microtomography are controversial. Among the newer technologies, data on thermal imaging can be considered as a viable option for detecting vertical fractures.
Purpose of the Study: This study aims to assess the thermal changes associated with dehydration for the detection and quantification of artificially induced fractures in teeth using infrared imaging.
Methodology & Theoretical Orientation: 49 extracted teeth, of which artificial fractures were induced in 31 teeth and 18 intact (without any fracture) control teeth were used, keeping them hydrated at all times. A FlukeTi400 infrared camera was used to capture a video of 60s-10s to capture baseline temperature, 40s drying period where compressed air at 30psi was released onto the occlusal surfaces producing a thermodynamic transient on the tooth surface, and final 10s period for temperature stabilization.
Findings: The maximum drop in temperature from baseline was 1.32°F, 1.47°F, and 1.37°F for the incisor, premolar and molar control groups whereas, it was 4.8°F, 7.99°F and 6.2°F for the fractured groups respectively. This comparison showed a p value of 0.015 for incisors and <0.001 for the premolar and molar group, indicating that thermal imaging can be a very promising method of diagnosis of tooth fractures due to its non-invasive and radiation-free mechanism.

Abstract:
Aim: The aim of this study was to investigate the effect of different double antibiotic paste (DAP) concentrations on viability and the gene expression of collagen type I in dental pulp stromal cells (DPSCs) cultured in presence or absence of TGF ß 1.
Methods: DPSCs between passage 6-8 were cultured in-vitro in the presence or absence of TGF β1 growth factor and the presence or absence of two different concentrations of DAP (1.5μg and 25μg) for 3 and 7 days. Cell viability was assessed under the different culture conditions as well as in the basal negative controls at both time points using LDS assay. The gene expression of collagen type 1 under the different culture conditions was investigated using qPCR; the gene expression of all groups was normalized to the expression in DPSCs cultured under basal culture negative control. Statistical analysis was carried out using one-way analysis of variance (ANOVA) and Bonferroni's multiple comparison tests.
Results: DPSCs cultured in TGF β1 without antibiotics showed the highest percentage of cell viability after three days. At seven days, the highest percentage of cell viability was in the group cultured with 1.5µg DAP. The 25µg and the 1.5µg DAP groups showed the lowest expression of collagen type I at both time points compared to their culture conditions. The highest expression of collagen type I were noticed at seven days in the 1.5 DAP+TGF β1 group.
Conclusion: In this study we have proven that DAP at higher concentration is toxic to DPSCs and hinders their ability to synthesize collagen type I whereas, the lower DAP concentrations were less destructive to DPSCs viability and to collagen type I gene expression. However, lower antibiotic concentrations are more likely to develop microbial resistance.

Abstract:
Ectodermal dysplasia is a relatively rare congenital disorder accompanied by total or partial anodontia affecting both the primary and the permanent dentitions. A patient was a 4-year old girl with ectodermal dysplasia. The intraoral examination revealed hypodontia. Treatment included reconstruction of the conical teeth using composite material in order to improve the aesthetics and to aid retention of the prosthodontic appliances. After reconstruction of the existing teeth, a removable partial denture for the missing teeth were chosen as a treatment option. The patient and her parents were found to be extremely satisfied with the improved chewing ability, speech and esthetics. prosthodontics, ectodermal dysplasia, anodontia with ectodermal dysplasia should be multidisciplinary and commenced as soon as possible to avoid possible resorption and atrophy of the alveolar ridges, to control the vertical dimension of occlusion, to improve chewing ability, speech and aesthetics.
