Abstract:
Solving special clinical situations in young children is allways a problemin pedodontic dentistry. During our day-by-day work at the Department of Pedodontics and Orthodontics of the Semmelweis University Faculty for Dentistry the most critical problems are related to early childhood caries, dental traumatic injuries in both primary and permanent dentition, molar-incisor-hypomineralisation syndrome (MIH), severe cases of hypodontia related to ectodermal dysplasia (ED) and the management of disabled children. The aim of this presentation is to highlight the clinical solutions and preventions methods applied in our department in the above mentioned situations by presenting general treatment protocolls, dental treatment under
general anaesthesia, non-invasive and minimal invasive treatment methods for children with special needs, deveopmental dental anomalies such as MIH syndrome, caries circularis, aesthetical and functional rehablitation of children who suffered traumatic injuries of the primary teeth and prosthetic treatment of young with hypohydrotic ectodermal dysplasia (HED). The case presentations of HED patients focus on long term monitorizing and the benefits of early prosthetic treatment on the development of the maxillo-facial structures.

Abstract:
By integrating oral health into strategies for promoting general health and by assessing oral needs in socio-dental ways, health planners can greatly enhance both general and oral health.The key concept underlying future oral health strategies is integration with this approach, a major benefit being the focus on improving health conditions in general for the whole population and for groups at high risk, thereby reducing social inequities. Problems in the mouth can signal trouble in other parts of the body. AIDS and osteoporosis are examples. Mouth lesions and other oral conditions may be the first sign of HIV infection, and are used to determine the stage of infection and to follow its progression to AIDS. The human mouth is home to millions of microorganisms, most of them harmless. Under certain conditions, however, some can cause oral infections such as tooth decay or gum disease. Oral bacteria may also enter the bloodstream if normal protective barriers in the mouth
are breached. This can happen as a result of dental treatment or even tooth brushing and flossing. Recent studies point to associations between oral infections – primarily gum infections – and diabetes; heart disease; stroke; and preterm, low-weight births. Research is under way to determine if the associations are causal or coincidental. Gum infections have been called "the sixth complication of diabetes," because people with diabetes are more likely to have periodontal disease. Researchers are exploring a possible two-way connection between the conditions to see if treating gum disease improve diabetic control. Recent studies point to an increased risk of heart disease and stroke in people with gum infections; the risk increases with the severity of the oral infection. Some studies have found that mothers of preterm, low birth weight infants tend to have more severe gum disease than mothers of normal birth weight babies. More research is needed to determine if gum infections do indeed
contribute to babies being born too soon and too small. Among tobacco users, oral cancer is a significant concern. Survival and treatment outcomes depend largely on stage of diagnosis. Early detection has the potential to improve the prognosis and quality of life for those diagnosed with oral cancer. Oral cancer statistics show that less than 40 percent of oral cancer cases are diagnosed at an early stage. A number of conditions of the oral mucosa may present as white patches. Although the majority
of white patches are of little significance, certain lesions are associated with pre-malignancy or malignancy. Unfortunately, the presence of any sinister lesion cannot be assesed by clinical appearance alone and definitive diagnosis, involving a biopsy, is mandatory whenever there is uncertainetly about the clinical diagnosis of an oral white patch.

Abstract:
Patients today usually recognize irregular teeth or obvious jaw deformities and seek treatment from orthodontist, who can
improve tooth alignment, function, and facial aesthetics. Dentofacial deformities require both orthodontics and surgery. These deformities affect physical oro-facial function in several ways. Approximately 30% of patients seeking treatment have a vertical increase in the lower third of the face. Because of the excessive vertical growth of the maxilla, the mandible trends to rotate downward and backward. These patients have problems in the anteroposterior plane. Patients with long faces can be described as being class I rotated to class II or as class III rotated to class II. Lip incompetence due to the excessive vertical growth of maxilla results in mouth breathing which eliminates the physiologic effect of the nose on breathing. The combination of surgery and orthodontics makes it possible to treat dentofacial deformities at ease. This paper highlights the importance in diagnosis and treatment planning, which would provide a predictable and stable outcome in vertical malocclusion associated
with skeletal class II and class III patients by orthognathic approach.

Abstract:
One of the most important goals of endodontic therapy is the complete elimination of microorganisms from the root canal system. Failure of root canal treatment is likely caused by the inability to eliminate the bacteria like Enterococcus faecalis which is responsible for refractory endodontic infections. Many studies have proven the high antibacterial potential of sodium
hypochlorite and it is the most widely used irrigation fluid. The use of lasers in endodontics is an innovative approach for disinfection as it generates expansion and successive implosion of fluids because of a secondary cavitation effect. The aim and objectives of the study were to compare the antibacterial efficacy of sodium hypochlorite, endo activator, diode laser, Nd: YAG
laser, Erbium: YAG laser and a combination of Erbium: YAG and Nd: YAG laser on Enterococcus faecalis in primary teeth. 48 extracted primary teeth were selected out of which 60 root canals were prepared and randomly divided into 5 groups.The canals were inoculated with an overnight culture of Enterococcus faecalis in tryptic soy broth for 24 hours. The baseline of
the culture was standardized and then the root canals were treated with the selected technique. Post exposure samples were cultured and the counts were recorded. All groups have shown bacterial reduction. Inter group no statistically significant difference was observed. (p>0.05).Nd: YAG has shown the best bacterial reduction. In conclusion, lasers when used along with
hypochlorite help us in achieving good reduction of Enterococcus faecalis counts. Further in vivo studies and studies including larger sample size are recommended.

Abstract:
Oral health is not just important, but also necessary for maintaining the overall general health in an individual. Many people assume that the deciduous teeth are not very important as they will be later replaced by the permanent teeth. Also, many parents do not check the oral health status of the child until problem occurs. But, the child needs a dentist at every phase
of oral development. Toddlers: Oral care must be started right before the eruption of the baby teeth into the oral cavity. Food habits must be taken
care of to avoid rampant carious lesions. Kids: Oral habits might lead to the maldevelopment of teeth. Also, children are most attracted to sugars during this age, which can lead to endodontic problems. Teenage: In this age, they are mostly towards the aesthetics, hence any malalignment cases must be taken care of. Also, many of the sports injuries cases are seen in this age group which must not be ignored. Hence, parents must be aware that at each stage,
the child’s oral health needs keep altering and it must be taken care of. Remember, GREAT BEGINNINGS HAVE GREAT ENDINGS. Objective of the abstract: To create awareness among children and their parents regarding oral health status at every stage in
a child’s life.

She is the youngest graduate Dentist among the 2017 cohort in Cameroon. She is member of the cameroonian board of Dental surgeon. She has also been Vice President of the Cameroon Dental Student Association and also member of several national and international scientific associations.
Abstract:
Statement of the problem: Preservation of the width and the height of alveolar crest following tooth extraction is a real challenge. Indeed, when a tooth is extracted, a bone resorption inevitably occurs. If uncontrolled, this vertical and horizontal bone loss could disrupt the stability of prosthesis and aesthetic demands. Perhaps, filling the sockets immediately after tooth
extraction with bone substitutes will help to minimize bone resorption which naturally occurs. Different averages of bone gain have been found. This study aimed to evaluate the clinical effect of bone substitute in alveolar crest preservation. Methodology: We realized a randomized clinical trial on 26 subjects divided into two groups. Firstly, we realized a traumatic
dental extraction. Then in 14 of the patients representing the treatment group, the surgical site was preserved with granules of Beta Tricalcique phosphate. The control group followed the same protocol except they did not receive the bone substitutes. The length of the study was six months and the primary outcome was an increase of the vertical height during the study
period. The secondary outcomes were the stability or the increase of the horizontal height and width of crestal bone. Finally, bone modifications of the alveolar crest were carried out through a clinical measurement (alveolar width) and radiologic measurements (horizontal and vertical heights). The measurements were performed respectively after 3 and 6 months.
Results: Six months after therapy, the width and the horizontal height were constant, but we observed a significantly increase of the vertical heights during the same period. In the control group the reduction of the width and both heights of sockets were significant. Conclusion: The use of bone substitute in filling sockets following tooth extraction has a beneficial and osteogenic
effect. Therefore, socket’s filling preserves alveolar volume.

Biography:
Dana Jafarpur is a sixth year dental student at Shiraz University of Medical Sciences. Next semester she will be graduating summa cum laude from Shiraz Dental School and has written a book in forensic dentistry and published 5 papers during her undergraduate studies.
Abstract:
Objectives: To evaluate the effect of different Nano filled resin coatings on the staining susceptibility of glass ionomer restoratives after immersion in three food simulating solutions (FSS). Methods: Five encapsulated glass-ionomer restoratives (Riva light-cure (SDI), Riva self-cure (SDI), Fuji II LC (GC), Fuji Bulk (GC) and Equia Forte Fil (GC)) and two Nano filled coatings (EQUIA Coat (GC) and G-Coat plus (GC)) were employed. All specimens were immersed in distilled water for 24 h and then subjected to a color measurement with a spectrophotometer. Then the samples were divided into three subgroups and immersed for another one week in lactic acid (0.1mol/L), coffee, and
distilled water (control) respectively. The differences in the lightness and chromaticity values (ΔL, Δa, Δb) were determined and the total color change (ΔE) was calculated using the formula: ΔEn=[( ΔLn)2+( Δan)2
+ ( Δbn)2]1/2 Results: Three-Way ANOVA showed a significant interaction effect between materials, coatings and solutions for the color change values. Therefore, one-way ANOVA was used to compare different variables between the materials. Color change values (ΔE) varied depending on the material and solution. G-Coat Plus exhibited lower color change values compared to the EQUIAcoated and the uncoated groups. The effect of immersion in FSS on color change values among materials varied depending on the type of coating.

Title: A comparison of quality of obturation and instrumentation using two rotary file system with manual instrumentation in primary teeth
Biography:
Satish Vishwanathaiah is currently working as an associate professor at Jazan University in Saudi Arabia
Abstract:
The primary tooth plays a vital role in growth and development of the jaws. One of the most important concerns in pediatric dentistry is the premature loss, leading to space deficiency. Various pulp therapy techniques have been put forwarded for primary teeth with pulpal involvement. Endodontic treatment [cleaning and shaping] of the root canals of primary tooth poses a challenge for the clinician due to its morphology. The success of the pulpectomy depends on elimination of irritants by means of cleaning and shaping the root canal. The procedure for cleaning and shaping with conventional technique [K files]
consumed more time and improper shaping of the canals and decreased volume of the obturating material. The evolution of rotary techniques and instruments has helped in overcoming these factors and provides an optimum shaping and obturation of the canal. The literature has shown improved canal preparation and changes in volume of the obturation with tapered files [PROTAPER and V Taper files] which uses more than one file. A new system Kedo S files [Single file technique] has been introduced which has shown some promising results in pediatric dentistry. With the introduction of new systems in field of rotary endodontics, the study aimed to compare and evaluate the clinical efficacy, canal preparation and volumetric filling using conventional files and two different rotary systems.

Title: Restoration of a peg lateral: A novel technique (Vacuum-formed splint delivery systems)
Biography:
Ayesha Javed is working as a private practioner in Bahrain.
Abstract:
This clinical case report describes the restoration of peg lateral incisors by conservative approach using direct composite bonding technique.
Introduction: A peg lateral is a developmental anomaly of the maxillary lateral incisors that cause a tooth to resemble a small peg. Incidence of peg and undersized lateral is 4%-5% in population. It is a heredity condition and has been linked genetically with tooth agencies. A peg-shaped incisor has a marked reduction in diameter, extending from the cervical region to the incisal
edge. The Different conservative treatment options include indirect and direct composite resin material. They can be carried out for peg-shaped laterals depending on the circumstances and the smile designs. A direct composite bonding is an ideal treatment as it is conservative and can be placed directly onto the tooth. Shape of tooth can be changed and additions can be
made to the length and width. Case report: Through this oral case report, I will be presenting an alternative direct treatment option for esthetically correcting
the peg laterals using the concept of a vacuum formed thermoplastic splint that has been fabricated utilizing a stone model copy of the definitive wax-up. Composite is then placed in the splint and placed over the teeth. Two patients aged 23 and 25 years old concerned about both sided peg shaped lateral incisors that were restored with direct resin composite laminate veneers using vacuum formed splint. Conclusion: This conservative technique produced highly esthetic outcome with durability and stability and gave these
patients new confident smile.

Title: Caries risk assessment in children between 6-18 in Budapest, Hungary
Biography:
Dora Zsofia Nagy graduated from Semmelweis University, Budapest, Hungary in 2014. Since then she has been working at the Department of Paediatric Dentistry
and Orthodontics at Semmelweis University. She is a specialist in paediatric dentistry and currently enrolled in the orthodontic residency programme. Besides the daily clinical practice, she has been involved in scientific research projects at the department and in the training of undergraduate students in the Hungarian, English and German speaking dentistry programmes.
Abstract:
Materials and Methods: Dental caries has been a major public health problem for many years in Hungary and still continues to be, affecting in many ways normal growth and development as well as social adaptation of children. A research on caries risk assessment was conducted at the Department of Paediatric Dentistry and Orthodontics at Semmelweis University with
116 children aged 6-18 (mean age: 10, 4). Based on the clinical dental status evaluation the prevalence of dental caries, DMFT, def-t, DF/df-T/t score, and Significant Caries Index (SiC) were calculated. For caries risk assessment the questionnaire of the American Dental Association was filled in by the patients' caretaker. Statistical data analysis was performed by using the
programme Statistica. Results: 83% of the children enrolled in the programme were regarded as 'high risk' patient, 15% as 'moderate risk' and only 2% as 'low risk' patient. The mean DMFT score of all study participants was 1,84 and the def-t score was 2,39. 20% of the patients were caries free. The overall SiC Index was 8,82. The data obtained revealed a significant correlation between caries and frequent sugar consummation, visible plaque accumulation, lack of dental home and high caries prevalence in the family. Discussion: The caries prevalence in children in Budapest declines but still exceeds the WHO recommendations. Therefore, the authors emphasise the importance of caries risk assessment as a prerequisite for appropriate preventive and treatment
intervention decisions.

Title: Assessment of first aid knowledge about tooth avulsion in paediatricians of Karnal city, Haryana (India)
Biography:
Isha Bisla is a student of Masters of Dental Surgery in the speciality of paedodontics and preventive dentistry in Pt. B.D. Sharma University of Health Sciences, Rohtak, Haryana, India
Abstract:
Seventy pediatricians practicing in various Government and private hospitals in Karnal city Haryana, India, were assessed for their first aid knowledge about incisor tooth avulsion in children. The responses of 70 pediatricians on a hypothetical clinical condition about tooth avulsion and its re-plantation in a 10 years old boy, were collected through a questionnaire having seven conceptual questions. The collected data were analyzed as a whole and in four different groups of pediatricians based on experience as G1, < 10 years, G2, 10 to 20 years, G3, 21 to 30 years and G4, > 30 years of experiences. The percentage
of pediatricians having different options for all seven questions were calculated and in addition to that knowledge-score of each pediatrician was calculated by assigning one and zero to right and wrong options for each question. The satisfactory knowledge about three questions viz. type of incisor tooth in a ten-year-old boy as permanent answered rightly by 71.43% pediatricians with
knowledge score (0.70±0.19), critical extra-alveolar time of the avulsed tooth should be within 15 minutes accurately answered by 67.14 % pediatricians with knowledge score (0.65±0.15), and the avulsed primary tooth need not to be re-planted answered appropriately by 60% pediatricians with knowledge score (0.60±0.16), were observed from this study. Average knowledge
about three questions viz. the ideal time for replanting the avulsed permanent tooth for the best possible prognosis is within 10 to 15 minutes accurately responded by 34.29% of pediatricians with knowledge score 0.33±0.06, Immediate management of permanent avulsed tooth by putting the avulsed tooth in its original socket and then refer to dentist rightly answered by
28.57% of pediatrician with knowledge score 0.28±0.043, about the optimum storage medium for avulsed permanent teeth to be re-planted after a longer period as (HBSS) answered correctly by 21.42 % of pediatrician with knowledge score 0.22±.094, were observed. Very poor knowledge about the proper handling of avulsed permanent tooth and its immediate gentle cleaning
with the easily available tap water was answered correctly by 8.57 percent of pediatricians with knowledge score 0.06±0.078 was bserved. Average mean knowledge score from all 70 pediatricians for all questions was observed as 0.40±0.24 which does not vary significantly from the mean knowledge score of different groups (p≥0.05). The present study did not demonstrate a strong
association between their first aid knowledge about tooth avulsion and length of experience.
Ehsan Iranmanesh
Kerman Medical University, Iran
Title: High performance polymers and their application as dental implants abutment
Biography:
Ehsan Iranmanesh is currently working as a Associate Professor in Kerman Medical University. He has several publications on dentistry.
Abstract:
Since the concept of Osseo integration was introduced by Brånemark et al, modern dental implants have been considered a safe and reliable option for replacing missing teeth. By placing dental implants abutment directly in in bone, considering different problems regarding its rejection, if every step is done by standard method the implant will be osseointegrated into
the alveolar bone. Osseointegration depends on a multiple of factors such as implant material, surgical technique etc. The implant material mostly include titanium and its alloys (mostly Titanium alloys Ti6Al4V) zirconia or even fiber reinforced composite (FRC) which can be a potential material in near future. For past few decades titanium and its alloys have been the material of choice for dental implant’s abutment. However, titanium has been shown to exhibit a variety of problems. Because of the high modulus of elasticity of the titanium alloys, dental implants made from the material can cause stressshielding
which may lead to periodontal bone loss. Moreover few cases has been reported with induction of hypersensitivity to the titanium used as implant’s abutment also other problems such as Wear debris and ion leakage can also be of concern with titanium dental implants. There is various factor concerning the success or failure of a dental implant by the manner in which stresses are transferred to the surrounding bone. Load transfer from implants to surrounding bone depends on the type of loading, the bone–implant interface, the quantity and quality of the surrounding bone and etc. Finite element analysis (FEA) allows researchers to predict stress distribution in the contact area of the implants with cortical bone and around the implants in trabecular bone. The high-performance biomaterial PEEK (polyether ether ketone) has been applied as implant material in many fields of medicine since the 1990ies.Due to its excellent properties, a high stability and elasticity (elastic
modulus: 3-4 GPa), low density (1,32 g/cm3) and insolubility its application have been boosted in the field of dentistry as for the manufacturing of prosthetic reconstructions. Its elastic modulus, similarly to that of cortical bone, it plays an important role as viable alternative to conventional implant materials such as titanium. This reduces the risk of stress shielding around the
implant and makes it suitable for use even in orthopedic procedures and spinal surgery. The stable chemical structure of PEEK makes it extremely unreactive and inherently resistant to chemical and thermal degradation. The inertness of the polymer also explains its biocompatibility, which has been shown both in vitro and in vivo. In this review article we inspect the probable advantages of using the PEEK as a stress shielding material in dental implant’s abutment.
