Keynote: Modern Pediatric dentistry : The way from past to future

Time : 10.00-10.40

Biography:

Head doctor in one of the Private dental clinics Dental Fantasy, Russia, Moscow. Works with children from the earliest childhood to teenagers (from infancy to adolescence). Uses operative microscope in daily practice since 2008.Clinical and scientific activity.Her publications focus on dental treatment in children of different age groups  by means of modern  technologies (for example, rubberdam (for kids), operative microscope, root canal treatment, crowns, conscious sedation, behavioural management e.t.c.) and preventive care (hygiene, preventive programs for kinds with primary and permanent teeth).The author of a training course for pedodontists: "Dental treatment for children - myth or reality ". Speaker of the educational centre Medical Consulting Group, Russia.

Abstract:

Today pedodontists face with not an easy task. It is necessary to keep children's dental health, for decrease of the development of caries risks and progressing oral diseases. The second important goal is  improvement of quality of life (functional and esthetic aspects are important). It is known that children's carious lesions appear at more young age (if compare prevalence with the period of five and, even, three-year ago). In light of this, pedodontists need to increasing their skills (both in non-medical and medical behaviour management, and routine dental manipulations). By the same token, parents of our patients want to get treatments without any stress for kids and with the most successful late fate for teeth. All abovementioned dictates requirements to the modern Paediatric practice. We understand that the dental clinic for kids nowadays has to provide treatment for patients from 0 to 18 years, has to use safety sedation and a high quality general anaesthesia, staff have to use communication  technicians (during conversation with children and parents). Treatment of primary teeth has to be done only once and be sufficient before eruption of permanent teeth. Treatment of the immature teeth has to rely on the principles of minimum invasive dentistry.

During the lecture I will answer 4 important questions:

1) How modern pediatric clinic looks like? (design, work conditions and patient’s logistics)

2) Which kind of modern technologies shall we use in daily practice? (composite restoration, rubber dam isolation, pulpitis treatment per one visit, crowns for kids, microscope as a daily technology)

3) Everything new is well-forgotten old: What we need for successful routine work? (choice, decision, plan)

4) Are children agree with us? Dental world by children’s impression (few words about behaviour management)

Yaron Haviv

Head at Orofacial Pain Clinic Israel

Title: Comparison between Orofacial Migraine and Painful Post Traumatic Trigeminal
Speaker
Biography:

Dentist and Oral medicine specialist. He is the Head of orofacial pain clinic in oral medicine department, Hadassah school of dental medicine
Jerusalem, Israel.Specialized in diagnosis and treatment of craniofacial pain and dental sleep medicine

Abstract:

Misdiagnosed of toothache can be attributed to several chronic types. This lecture will discusses one major underestimate candidate: Orofacial Migraine (OFM), (previously Neurovascular Orofacial Pain (NVOP)), is often misdiagnosed as persistent idiopathic facial pain (PIFP) or post-traumatic trigeminal neuropathy (PTTN). This lecture will present a retrospective study aimed to reestablish diagnostic criteria for OFM compared to PTTN.

 METHODS: Pain and patient characteristics were compared in patients with: OFM, PTTN and OFM with additional trauma (PT-OFM). OFM criteria were based on prior studies; PTTN was defined according to the International Headache Society.
RESULTS:  Of the 171 patients in the cohort, 90 had PTTN, 52 had OFM and 29 had PT-OFM. Since all parameters matched, the OFM and PT-OFM groups were combined (T-OFM). T-OFM differed significantly from PTTN (P<0.001) in its periodic pain pattern, presence of autonomic and systemic signs, throbbing pain quality and frequency of bilaterality. Pain quality in PTTN was more burning/stabbing than OFM (P=0.003).  Pain severity, location, waking from sleep, muscle sensitivity to palpation and demographics were comparable.

CONCLUSION: OFM differs from PTTN in the periodicity of pain, presence of autonomic and systemic signs, throbbing pain quality and more often being bilateral. OFM diagnosis should be included in the differential diagnosis of all cases of PIFP. Distinguishing OFM from PTTN and PIFP affects treatment and prognosis.

Abstract:

Dental caries, which is also referred to as tooth decay or cavities, is one of the most common and widespread persistent diseases today and is also one of the most preventable. When you eat certain foods, the bacteria on your teeth breaks them down and produces acids that have the ability to seriously damage the hard tissues of your tooth. The result is the formation of dental caries (cavities). Dental caries causes through a complex interaction over time between acid  producing bacteria and fermentable carbohydrate and many host factors including teeth and saliva. The cavities may be a number of different colours from yellow to black. Typically, dental caries can be spotted on two specific areas of the teeth: occlusal caries, which form on the top most part of the tooth where food particles repeatedly come in direct contact with the teeth and interproximal caries, which are dental caries that form between the teeth. It’s in these two locations where bacteria fester and pose a risk to your oral hygiene. If the teeth and surrounding areas are not cared for properly, the bacteria will begin to digest the sugars left over from food in your mouth and convert it into acids as a waste product. These acids are strong enough to demineralize the enamel on your teeth and form tiny holes—the first stage of dental caries. As the enamel begins to break down, the tooth loses the ability to reinforce the calcium and phosphate structures of the teeth naturally through saliva properties and, in time, acid penetrates into the tooth and destroys it from the inside out. According to the WHO report, dental caries remains a major public health problem in most industrialized countries, affecting 60–90% of school children and the vast majority of adults. The WHO oral health report (1–3) noted that dental caries can be controlled by the joint action of communities, professionals and individuals aimed at reducing the impact of sugar consumption and emphasizing the beneficial impact of fluorides Treatment of dental caries is fillings  are the most common form of treatment for the disease and Crowns are another option for dental professionals when treating dental caries, Root canal Another method of treatment, a dental professional may employ is called a root canal and Extraction In some cases, the tooth may be damaged beyond repair and must be extracted if there is risk of infection spreading to the jaw bone Most children have signs of some inflammation of the gingival tissue at the necks of the teeth among adults the initial stage of gum disease is prevalent this condition is termed gingivitis .

Biography:

Dr. Mohammed Yehea serves as a Lecturer and clinical instructor in at Qassim University, College of dentistry, Qassim, Saudi Arabia. He maintains his enthusiasm for education. His lectures cover topics including digital dentistry, advanced restorative dentistry and tooth colored restorations and he is published in few acclaimed dental journals. He is a Prosthodontist and has an excellent reputation for carrying out his clinical work to the highest level of precision and expertise. Dr. Yehea obtained his Master Degree (M.Sc) in Fixed and Removable Prosthodontics  from Jordan University of  Science and Technology. Irbid, Jordan. His research focus is in Digital impression and CAD-CAM produced prosthesis, both single, multiple and metal framework for fixed and removable partial dentures, through a variety of manufacturing techniques; additive (3D printing) and subtractive technologies.

 

 

Abstract:

Purpose: The dimensional accuracy of recently introduced dental restoration taken by digital intra-oral impression initially   and then fabricated by additive manufacturing or the so-called 3D-printing technique is not well established and it may play a significant role in the future of dental technology.

Materials and Methods: This in vitro study presents a comparative experimental evaluation of dimensional accuracy of all-ceramic crown (fig 1) restorations fabricated by using two approaches: additive and subtractive manufacturing. The all-ceramic crown is digitally designed on molar die by using Computer-aided design (CAD) software. Samples are fabricated by using six different methods ( n=12 each group, total N=72), including three additive manufacturing techniques, stereolithography apparatus (SLA, fig 2), digital light processing (DLP, fig 3) and photopolymer jetting (PPJ,  fig 4) ; and three subtractive techniques, wax, acrylic and e.max ceramic milling. The samples are scanned by using a high resolution optical surface dental scanner and then compared by overlapping reference data. The dimensional accuracy are evaluated by 3D-deviation analysis method. The 3D digital files of the scanned fabricated all-ceramic crowns (test model) are exported in standard tessellation language (STL) format and superimposed with the STL file of the designed all-ceramic crowns (reference model) using Geomagic Studio (3D Systems). The results are statistically analyzed using a  one-way analysis of variance (a=0.05). Moreover, the surface morphology of one randomly selected sample from each group are evaluated using a digital microscope.

Results: The root mean square estimate value and color map results suggest that after digital intra-oral impression, additive and subtractive manufacturing  have an influence on the dimensional accuracy of 3D-printed crown restorations. Among the tested groups, the SLA group showed a minimal deviation of 0.029 mm for thin support and 0.031 mm for DLP group, indicating an accurate fit between the test and reference models. Furthermore, the deviation pattern observed in the color map was homogenously distributed and located further away from the critical marginal area.

Conclusions: Within the limitations of this study, The results indicate that the accuracy of dental restorations htaken by digital intal-oral impression and fabricated using the additive manufacturing methods (SLA) is higher than that of subtractive methods. Therefore, this method is a viable alternative to subtractive methods.
