Ahmed Halim Ayoub

Egyptian society of Oral Implantology, Egypt

Title: Novel approach for soft tissue management in esthetic zone

Biography:

Ahmed Halim Ayoub has accomplished diploma and master degrees is from Seville University, Spain. He developed expertise in bone augmentation and sinus elevation and has special interest in bone healing. Currently he is the visiting lecturer in Bari University, Italy. He provides live training throughout directing dental implant post graduate training in Egyptian society of oral implantology, London oral restorative Academy, and London dental education services. He is a distinguished speaker and presents at international conferences and teaches in the Rome, Europe and the Middle East.

Abstract:

Management of peri-implant soft tissue is as important as preserving the peri-implant bone level. Many techniques, approaches, and materials have been used to achieve healthy, keratinized, esthetic peri-implant soft tissue or correct/augment any deficiency in it. Platelets rich fibrin (PRF) or concentrated growth factors (CGF) is one of those materials that can be used to achieve soft tissue augmentation, especially in esthetic zone. Osseointegration is no longer considered the only parameter upon it we can judge the success of the implant therapy. Even precise ceramic duplication of the contour, shade, and translucency of natural dentition may still result in an aesthetic failure if the gingival profile, color and texture are compromised. Therefore, the functional and aesthetic success of implant treatment in the anterior esthetic zone depends not only on the quality of the restoration but also on the final aspect of the contour and stability of the marginal gingiva and the proximal papillae in harmony with the adjacent teeth.

Johann Lechner

Clinic for Integrative Dentistry, Germany

Title: Hyperactivated signaling pathways of chemokine RANTES/CCL5 in osteopathies of jawbone in cancer and autoimmune diseases: Neglected dental cause of systemic diseases?

Biography:

Johann Lechner is a dentist, Naturopath and the Head of the Clinic for Integrative Dentistry in Munich, Germany. He also serves as a member of executive board of DAH (German Association for Research on Disturbance Fields and Regulation). Besides extensive lecture and seminar activities in USA, Europe and China, he published numerous articles and hitherto nine books in German about Holistic Dentistry and Integrative Medicine. He has published 6 PubMed indexed scientific papers discussing immune messengers and hyperactivated signaling pathways by RANTES/CCL5 in jawbone and systemic interference. These studies done by him are the first ones worldwide and contribute to generating a new field of Maxillo-Mandibular Osteoimmunology.

Abstract:

Despite significant therapeutic advances most malignancies, as well as adenocarcinomas of the breast, remained incurable. At the same time, the importance of the microenvironment surrounding the tumor cells with “silent inflammation” increases. To check the suspected tumor-relevant inflammatory cytokine sources in fatty degenerative osteonecrotic jawbone (FDOJ), we analyze these conspicuously altered jawbone areas to assess the expression and quantification of cytokine expression. In 38 tumor patients we determine the levels of cytokines by bead-based Luminex® analysis in samples of FDOJ. Striking is the high content of chemokine RANTES/CCL5 (R/C) in all 38 jawbone tissue samples of cancer patients. A single case is characterized by high R/C levels in FDOJ sample and simultaneously by metastasizing cells inside the FDOJ sample. The R/C expression in all 38 FDOJ samples is on average at 35 fold higher compared to healthy jawbone. R/C interacts on several levels in immune responses and is considered in scientific literature as pathogenetic key point in tumor growth. The study supports a potential mechanism where FDOJ is a mediating link specifically in breast cancer (MaCa) and its metastasis. R/C is thus involved intensively in oncogenic propulsion progress developments. The authors conclude from the data of FDOJ analysis that these areas express hyperactivated signal transduction of the chemokine R/C, induce pathogenetic autoimmune processes in tumors, MaCa and its metastasis and serve as a possible cause. The authors hypothesize that such changes in areas of improper and incomplete wound healing in the jawbone may lead to hyperactivated signaling pathways, and result in unrecognized sources of silent inflammation which may contribute to systemic disease patterns like cancer. Combining the R/C signal induction of tumors and the information we collect illustrated, it may be suggested to involve FDOJ in an integrative concept for tumor therapy.

Sameh Samy Abdou

Egyptian Society of Dental Implant, Egypt

Title: Keys to success for implants placement with immediate loading

Biography:

Sameh Samy Abdou has completed master degree in prosthodontics in 1992 from Alexandria University Egypt. He has received diploma in Implantology from Sevilla University Spain in 2007. He has been the Consultant in Prosthodontics & Implantology since 2002.

Abstract:

The introduction of osseointegrated implants in dentistry represents a turning point in dental practice. The concept of immediate loading has recently become popular due to less trauma, reduced treatment time, high patient acceptance and better function and esthetics. A careful case selection, proper treatment plan, meticulous surgery and proper design of prosthesis are essential for optimal outcomes when this approach is adopted.

Jean-Marc Dersot

French Society of Periodontology and Oral Implantology, France

Title: Optimizing periodontal conditions around the maxillary included canine: Proposal of a surgical decision tree

Biography:

Jean-Marc Dersot is the doctor of Dental Surgery. He has completed MSc, PhD and the former assistant-professor at the Periodontology department of Paris 5, former president of the French Society of Periodontology and Oral Implantology (SFPIO), associate member of the National Academy of Dental Surgery (ANCD), international member of the American Academy of Periodontology (AAP), expert near the Paris Court of Appeals, practice limited to periodontics, oral surgery and implant - Paris – France.

Abstract:

Currently, it is considered acceptable to hold dolphin, orca, beluga and other cetaceans in captivity for human entertainment. Clearly, among the most emotionally and socially complex of all creatures, there is an urgent need to recognize and acknowledge the sentience of these beings. Moreover to rewrite global protocols and accepted norms in order to drive a systematic and comprehensive phasing out of this archaic, cruel practice. Cetaceans are to this day still being taken from the wild, with devastating consequences for those captured and family members left behind, in order to fulfill demand for hotels, waterparks and other facilities around the world. We must discuss and become the catalyst for an end to this.

Steven Traub

American Institute of Oral Biology, USA

Title: Immediate post-extraction molar dental implants

Biography:

Dr. Traub obtained his dental degree at Creighton University in Omaha, Nebraska. He completed his oral and maxillofacial surgery residency training at Cook County Hospital in Chicago. He maintains a private practice in Albuquerque, New Mexico (USA) and is on the board of directors of the American Institute of Oral Biology (AIOB). He is a fellow of numerous oral and maxillofacial surgery associations, both in America and internationally. He lectures extensively throughout the world.

Abstract:

Contrary to early dogma related to titanium implant integration, 100% bone to metal contact, complete wound closure, and peri-implant socket bone graft placement are not absolute determinants of success. In fact, adequate stabilization in an extraction site with normal osteogenic healing potential leads to the same result in molar wounds, both in the maxilla and mandible, with essentially equal predictability. This lecture documents a 12-year private practice clinical investigation using a single brand (Biomet 3i) implant for both root canal and non-root canal teeth with a standard follow-up protocol for over 700 consecutive cases.

Jean-Marc Dersot

French Society of Periodontology and Oral Implantology, France

Title: Optimizing periodontal conditions around the maxillary included canine: proposal of a surgical decision tree

Biography:

Abstract:

In front of the maxillary lateral incisor agenesis (MLIA), the therapeutic options are multiple. Opening or closure of the space, extraction of the sometimes peg-shaped contra-lateral incisor, removable temporary prosthesis, Maryland bridge, bonded cantilever bridge, conventional bridge, implant. MLIA diagnosis is made early by radiographic examination and, from the beginning of the orthodontic phase, it is important to know if the implant solution can be performed. The implant feasibility must meet certain conditions concerning: the bone corridor: height and thickness of the bone, the width of the mesiodistal space and parallelism of the roots of the two adjacent teeth. However, in 60 to 85% of cases, it is necessary to reconstruct the bone and/or gingival structures beforehand. A lingual treatment of a bilateral MLIA illustrates this thinking. The cost/benefit/ safety ratio, but also the age at which the orthodontic treatment is performed, can help to choose the most suitable and most durable solution. Several studies, carried out on the maxillary anterior area, specify what can be the evolution of an implant, 15 to 20 years after its installation, and the results are quite disappointing.

Dania Siddik

Consultant Pediatric Dentistry, UK

Title: Special Session: Recurrent aphthous stomatitis; Overview and suggested management modality in pediatric dentistry

Biography:

Dania Siddik is a consultant pediatric Dentist based in London specialises in the management of dental injuries, sedation and general anaesthesia for anxious children and oral surgery. In addition to practising dentistry, she also held a position teaching both undergraduates and post graduates at the King’s College University pediatric dentistry department. She is a regular examiner for the MJDF and ORE courses at the Royal College of Surgeons of England.

Abstract:

Aphthous ulcers also known as recurrent aphthous ulcers, aphthous stomatitis, recurrent aphthous stomatitis [RAS], or canker sores; are a common oral mucosal disease. They are ulcerations with no known cause and a wide spectrum of severity and frequency of recurrence. Clinically, RAS has different presentations. It can consist of solitary or multiple ulcers, usually on the non-keratinized oral mucosa. It has been proposed that aphthous ulcerations represent an autoimmune reaction and may be precipitated by stress or hormonal changes. I will be discussing the importance of right diagnosis and monitoring with a specific scoring system. I will discuss as well the predisposing factors, the microorganisms implicated in aphthous ulcers as well as different treatment modalities for the pediatric patient. I will discuss the clinical presentation of this condition together with the current views on the aetiology and pathogenesis of the disease.

Nur Ozel

Izmir Educational Dental Hospital, Turkey

Title: Keynote Forum: Evaluation of interleukin-1 beta level and oxidative status in gingival crevicular fluid during rapid maxillary expansion

Biography:

Nur Ozel does private practice in Izmir and is currently running as a clinician in Izmir Education Dental Hospital, Izmir/Turkey. She is a member of the Turkish Orthodontic Society and an affiliate member of the American Dental Association. She has been a certified incognito System user since 2017. To date she has published 5 various articles in various journals in dentistry.

Abstract:

The levels of interleukin-1beta (IL-1β), nitric oxide (NO), total antioxidant capacity (TAC), and total oxidant status (TOS) in gingival crevicular fluid (GCF) were determined during rapid maxillary expansion (RME) treatment. Fourteen patients (10-13 years old) were included. A modified hyrax appliance was used for the treatment. After periodontal parameters were recorded, GCF was collected from the first molars at each observation [T1:baseline: 14 days after periodontal prophylaxis and instructions; T2: 1 day later hyrax inserted, at passive position; T3:1 week later; after the first activation; T4: after 2 x 1/4 activation; T5:after 7 x 1/4 activation; T6: after 14 x 1/4 activation; T7:retention period on the 1st month; and T8:retention period on the 3rd month]. Although the levels of IL1-β, NO, and PD increased significantly from T1 to T2, the GI, BOP%, and PI remained unchanged throughout treatment. GCF volume at buccal and palatal surfaces increased significantly from T1 to T4, T6, T7, and T8. The parameters in GCF and TAC levels were not only higher at palatal side in comparison with buccal, but also TOS levels increased at both buccal and palatal sides. In this study, the differences of oxidative status and IL-1β levels during RME treatment could be attributable to orthopedic effect of the heavy forces on maxilla and minimal orthodontic forces on teeth applied by the RME apparatus.

Abdullah Mohammed Alzahem

King Saud bin Abdulaziz University, Saudi Arabia

Title: Keynote Forum: Importance of cheek-bite keratosis in diagnosing temporomandibular disorders

Biography:

Abdullah Mohammed Alzahem is the assistant professor of medical education. He specialises in temporomandibular joint disorders and advanced general dentistry. He is appointed as associate dean and director of Quality Assurance in King Saud bin Abdulaziz University for Health Sciences.

Abstract:

Cheek-biting commonly reported by patients with Temporomandibular Disorders (TMDs). This check biting may cause cheek-bite keratosis. This research aim is to study the prevalence of cheek-bite keratosis among TMDs patients. Cross-sectional survey conducted on 373 TMDs patients seen in the TMJ clinic by one TMJ specialist since 2013. Convenient sampling technique was followed where all screened patients having TMDs included in the study. TMDs patients who have check-bite keratosis are 226 patients (60.6%). Female TMDs patients are the majority (75.60%) and 78.8% of TMDs patients with cheek bit keratosis were female. The highest numbers of TMDs patients (4.6%) were at age of 20 years old. Cheek-bite keratosis is an important sign for TMDs screening for the general dentist in the first dental visit. Dentist who find cheek-bite keratosis during intra-oral examination, advised to ask more screening questions and do more clinical examination for TMDs.

Eric Hazan

Cabinet of Restorative Dentistry, Prosthetics and Esthetics, Paris

Title: Special Session: Porcelain laminate veneers and parafunctionnal habits : The impossible equation?

Biography:

Eric Hazan is a private practitioner since 1988, oriented to restorative, prosthetic and esthetic dentistry since 1991. He was the former president of the American Dental Club of Paris and member of the board and also the former president of Societe Odontologique de Paris and member of the board. He is an active member of American Dental Club of Paris, Societe Odontologique de Paris, and American Academy of Fixed Prosthodontics International College of Prosthodontists Pierre Fauchard Academy.

Abstract:

Parafunctional habits will have a profound impact on the form and function on hard dental tissues with premature wear of enamel and dentin, resulting in fissures, cracks, and dental fractures with important impacts on pulp biology and/or periodontium. Consequences include a profound and durable modification on the orofacial elements, as masticatory muscles and temporomandibular articulations. These deformations will lead to functional problems that could be detrimental for the proper function of our patients. The goal of this lecture will be to understand and identify the different diagnoses and treatment plans that are associated to them, so we could resolve complex restorative and prosthetic problems. We will see closely the utilization of new paradigms by the rehabilitation of the Porcelain Laminate Veneers, which represent nowadays an alternative solution to the full crown. This is particularly true with the emergence of full porcelain materials and techniques. The therapeutic fields becoming larger and more complex for the clinician. We will see also the specific relationship that is bonding the prosthetic restoration to the marginal periodontium, and see how we should handle this relationship to obtain a durable and constant result, knowing how difficult it is to capture properly the cervical margins for a good result.

Alkis Konstantinopoulos

Dental Design Lab, Greece

Title: Special Session: Dental prosthetics with predictable outcome

Biography:

Alkis Konstantinopoulos completed the Greek National School of Dental Technicians in 2005. He owns dental laboratory which is nowadays one of the most state of the art and fully equipped in Greece, “Dental Design Lab”. In addition, he has published many papers in reputed journals while also he has been invited as an expertise speaker to many conferences worldwide. Furthermore, he is also cooperating with many dental technology companies as a technical consultant.

Abstract:

This presentation is to show how predictable outcome can be achieved in high aesthetic dental prosthetics through digital designing and manufacturing techniques. One of these techniques is 3D prototype printing with DLP printers through the use of certified surgical resins and milled resins prototypes. In addition, this presentation will show how patient wishes/orders can be fulfilled and imprinted in the final outcome through digital designing tools like Exocad True Smile and also how the use of polarized dental photography can lead to an exact and correct communication between the patient, the dentist and the laboratory. As a result, function difficulties are avoided while also changes and/or remakes are not necessary which means the durability and strength of the final prosthesis are not affected. Finally, all above techniques diminish manufacturing and delivery time while also the patient’s stress period as he/she is certain for the final outcome of the prosthesis since the beginning of the procedure.

Merieme Lferde

Mohammed V University of Rabat, Morocco

Title: Intrusive luxation: From reflexion to decision: About two case reports

Biography:

M Lferde is the former intern at Ibn Sina University Medical Center, resident in pediatric dentistry, faculty of dental medicine at Mohammed V University of Rabat Morocco. She is a member of the committee bureau (communication manager) of the association of internal and residents dentists of Rabat.

Abstract:

Dental intrusion corresponds to the axial displacement of the tooth into the alveolar bone. Rather infrequent, it represents between 0.3 and 1.9% of traumas in permanent dentitions. It occurs mostly in children between the ages of 6 and 12 and generally affects only one tooth. Case report First case: The patient, B.K, was a 9-year-old child that reported to the Rabat Dental Treatment and Consultation Center (DTCC) in an emergency following a fall at home. After clinical and radiographic examination, the diagnosis of the intrusion of the two immature central maxillary incisors was made. The management of the case consisted of the therapeutic abstention with regular followup. Spontaneous re-eruption of the teeth occurred 3 weeks after the trauma. Second case: The patient Z. M was a 14-year-old teenager, who was sent to the DTCC of Rabat in an emergency following a public road accident. After clinical and radiographic examination, the diagnosis of the intrusion of the upper right central incisor was made. The treatment consisted of a surgical repositioning of the tooth. The clinical and radiological follow-up of the two clinical cases was spread over 18 months. Intrusive luxation is the most severe form of dental trauma. Axial shock usually causes considerable pulpal and periodontal complications. The treatment is complex since the prognosis is often unfavorable with inevitable complications. To date, no treatment has been found better than another. Besides, the incidence of pulp necrosis, all methods combined, varies from 45% to 96%. The therapeutic modalities depend on the age of the child, the stage of the root formation but also the importance of the vertical dislocation. Intrusive luxation, although rare, is the most severe form of traumatic emergencies. successful treatment requires a rigorous clinical and radiographic examination that allows reasoned decision-making ranging from therapeutic abstention to active repositioning.

Pirkko-Liisa Tarvonen

Rayo 3D-Toothfill Ltd, Finland

Title: Challenges related to direct filling with composite resin restorations among Finnish dentists

Biography:

Pirkko-Liisa Tarvonen has a specialist degree in Dental Public Health from the University of Turku, Finland, and a Ph.D. degree from the University of Eastern Finland. She acts as dental marketing director at Rayo 3D-Toothfill Ltd and is university lecturer at the University of Helsinki and at the University of Eastern Finland. As a volunteer project coordinator for ten years, she has had a remarkable contribution in the support of primary dental care and dental education in the Democratic People’s Republic Korea.

Abstract:

Dental caries remains as one of the main health problems globally. Over the past decades, resin composites have gradually replaced amalgam as the main direct filling material. However, there are several shortcomings with this technique, especially larger fillings in lower posterior teeth are challenging. Indirect restorations are used to overcome the challenges linked with direct restorations. Objectives: To evaluate the challenges related to direct filling technique with composite resin restorations among Finnish dentists. An electronic questionnaire was sent to 3,777 Finnish dentists. Respondent’s age and the challenges with direct filling technique with composite resin restorations were inquired by multiple-choice questions. The number of replies was 760 and the response rate was 20.1%. The responses were grouped by age in five subgroups of ten years each, and the statistical differences between the age groups were analysed using Chi-square tests with the statistically significant level at p<0.05. The main shortcomings and challenges related to large (3 or more surfaces) direct composite fillings were poor survival rate (57.4%) and moisture sensitivity (49.9%) followed by polymerization shrinkage (38.8%), time-consuming technique (34.5%) and poor accuracy (16.3%). Poor survival rate (p<0.001) and poor accuracy (p<0.001) were reported more frequently by younger dentists than the older ones. Concerning the other challenges, no statistically significant differences were found between the age groups. Dentists reported shortcomings related to direct dental composite filling methods. The findings give support to the development of new indirect techniques for cost-effective restorative treatment. RAYO 3DToothFill is a novel technique utilizing digital imaging and 3D printing to fabricate tooth fillings and other dental restorations. The innovation is developed by a team of professors and experts from the University of Eastern Finland and University of Oulu, Finland.

Sung-Woong Hur

Chonnam National University Dental Hospital, South Korea

Title: Guidelines for computer guided implant surgery; Minimizing errors and maximizing accuracy of surgical guides

Biography:

Sung-woong Hur has completed his DDS, PhD from Chonnam National University School of Dentistry, Korea and PhD (Dental Science) from Tohoku University, Japan. He has published several papers in reputed journals and his recent publication was published in Journal of Dental Research (2015). In the present, he is the representative of Gwangju TOP dental clinic, Korea and is serving as a clinical professor of Chonnam National University School of Dentistry.

Abstract:

Up to date, computer guided implant surgery (guided surgery) is being hotly debated in the field of dental implantology. The present cases were studied to find out the basis of using surgical guides, and further to establish an optimal guideline for using them in practical dental implant surgery. 108 stereolithographic surgical guides were fabricated by the uses of computed tomography (CT) scans integrated with three-dimensional (3D) virtual planning software and computer-aided design/ computer-assisted manufacture (CAD/CAM) process (Osstem®). 179 implant fixtures were placed to 82 patients using those surgical guides for about 18 months. All the surgical procedures were performed by one dentist at one local dental clinic (Gwangju TOP dental clinic, Korea). The cases included various situations such as single/multiple missing state, sinus bone augmentation, guided bone regeneration (GBR), narrow ridge and partial edentulous. A total of 179 dental implants were finished up to the final prosthesis and evaluated by clinical and radiographic method. From this study, it shows that the success of guided surgery depends on how we minimize errors and maximize accuracy of surgical guides. If once this goal is achieved, exceptionally precise placement of implants could be possible, followed by higher survival rate of implants, at the same time make surgical procedures much simpler with less complication. To conclude, it is certain that computer guided implant surgery is a reliable tool and can be applied broadly if performed in an appropriate manner.

Francesco Campione

Private Practice Roma, Italy

Title: SS Fly: A therapy for root re-implantation

Biography:

Francesco Campione specializes in CAD / CAM technology at the University of Zurich. He collaborates with Prof. Ernesto Rapisarda for the University of Catania for the realization of numerous conferences on the theme “aesthetics of the front group” (ceramic veneers). He practices a free profession between Catania and Rome and collaborates as a scientific researcher with Prof. Dai Kawahara, director of dental materials at the University of Osaka.

Abstract:

The therapy that we propose, unlike normal regenerative protocols, is a technique called SS fly, which unlike the Socket Shield consists of an autologous graft of the extracted root, appropriately processed out of the mouth and immediately re-implanted into the original site. With this technique we obtain positive results in the short term, with a very satisfactory medium-term maintenance that is very promising even in the long terms. Moreover thanks to the use of cono morse taper connection, which makes possible to decouple the prosthesis from the implant, we can control the position and, if necessary, adjust the structure from the third week after the insertion. The extraction and customisation of the root (out of the mouth) do not involve great technical difficulties and are very simple to carry out with the patient in the chair. In addition, no filler is required, but a simple provisional that acts as a camera and umbrella concept.

Title: The importance of hospital dental care in the treatment of oral mucosite in pediatric oncological patients Juliana

Biography:

Juliana Francisca Grossi Heleno, graduated in dentistry from PUC-MG academic highlights PUC-MG 1997, 1998 and 1999 postgraduate in pediatric dentistry by UFMG post-graduate in fixed prosthodontics and periodontal surgery, UNIP-SP postgraduate in implantology APCD-SP qualification in Hospital Odontology Albert Einstein Hospital, SP endodontic professor at FUNORTE BH / Ipatinga, MG master in endodontics PUC, MG dental surgeon at Hospital of Baleia - BH Brazil

Abstract:

Annually, more than 300,000 new cases of child and adolescent cancer are diagnosed worldwide, according to the International Agency for Research on Cancer. The numbers are no less alarming in Brazil, in which childhood cancer already reaches the second cause of death among children. The subject increasingly demands the implementation of emergency actions for prevention, early diagnosis and treatment, with a joint and multidisciplinary effort. Most cases require chemotherapeutic treatment, which often results in oral mucositis, the most frequently documented side effect in pediatric immunosuppressed pediatric patients. These oral lesions lead to a considerable impact of quality of life during treatment due to dysphagia, dysarthria, odynophagia and malnutrition. In addition, these injuries contribute to a gateway to opportunistic infections, discontinuation of treatment, longer hospital stay, hospital costs, and often lead to death in more severe cases. The Dentist plays a key role in the hospital setting to diagnose, treat and prevent such injuries. One of the treatments consists of low-intensity laser therapy, which has become one of the most recent and promising treatments, reducing the severity and duration of oral mucositis, and preventing future lesions. This study aims to show the effectiveness of laser therapy in reducing the degree and time of remission of pediatric oncology patients by chemotherapy. We will describe a series of cases, with a quantitative approach, in children from 0 to 19 years of age at a referral hospital in the State of Minas Gerais, Brazil, who had a diagnosis of oral mucositis after chemotherapeutic treatment. The group received daily sessions of Laser Therapy and to evaluate the lesions, a daily recording of the lesions was performed, following WHO protocol. Laser therapy has been shown to be effective in reducing the time of remission and severity of oral mucositis in infantojuvenis patients undergoing chemotherapy.

Title: Prevalence of Gingivitis and Periodontitis in Saudi adult male population and the ABO blood group distribution

Biography:

Mohammad Parvaiz Farshori, working as an Assistant professor in department of physiology in college of medicine, and the coordinator of physiology program at college of in college of dentistry at university of Hail in Saudi Arabia.

Abstract:

Many studies have reported a high prevalence of periodontal diseases among Saudi children and the male and female adult population. Saudi Arabia has a very high prevalence of obesity and diabetes. Many earlier studies have suggested about three fold increase in the incidences of periodontitis among diabetic patients. We recently reported a very high prevalence of periodontitis among the diabetic adult female patients. We found a significant increase in tooth loss and tooth decay among diabetic patients. In the recent past many studies have shown an association between the inheritances of blood groups with hypertension, cardiovascular disease, diabetes and many kinds of cancers.Although many studies have been published to report ABO blood group distributions among Saudi population but to the best of our knowledge to date no studies have been done to show an association between gingivitis and periodontitis and ABO blood groups. In the current study we wanted to analyze the possible association between the inheritance of ABO blood groups and the incidences of gingivitis and periodontitis among Saudi adult male population.Oral exams were performed by dental interns on a total of 400 randomly selected male subjects and their ABO blood group was recorded. Next we recruited 460 male subjects who either had gingivitis and or periodontitis and their ABO blood group information was recorded. Their oral cavities were thoroughly examined for the presence of dental carries, gingivitis, periodontitis, and tooth decay and or tooth loss. Data was carefully recorded and analyzed.Our blood group distribution analysis of gingivitis and periodontitis patients showed 3.26% to be A-, 5.43% were A+, 2.82% were B-, 13.7% were B+. 3.04% were found to be AB- and 8.9% were AB+. O blood group was the most prevalent blood group with 8.04% were O- and 52.39% were O+. There is a significant increase in prevalence of periodontitis in male diabetic patients as compared to the control group. Our results also show increased tooth loss among diabetics as compared to the control non diabetic patients. There was a significant decrease in prevalence of A blood group and a significant increase in distribution of O blood group among patients with gingivitis and or periodontitis.

Title: Evaluation of interleukin-1Î² level and oxidative status in gingival crevicular fluid during rapid maxillary expansion

Biography:

Nur Ozel does private practice in Izmir and is currently running as a clinician in Izmir Education Dental Hospital, Izmir/Turkey. She is a member of the Turkish Orthodontic Society and affiliate member of the American Dental Association. She has been a certiï¬ed incognito System user since 2017.To date she has published 5 various articles in various journals in dentistry.

Abstract:

The levels of interleukin-1β (IL-1β), nitric oxide (NO), total antioxidant capacity (TAC), and total oxidant status (TOS) in gingival crevicular fluid (GCF) were determined during rapid maxillary expansion (RME) treatment. Fourteen patients (10-13 years old) were included. A modiï¬ed hyrax appliance was used for the treatment. After periodontal parameters were recorded, GCF was collected from the ï¬rst molars at each observation [T1:baseline:14â€¯days after periodontal prophylaxis and instructions; T2:1â€¯day later hyrax inserted, at passive position; T3:1 week later; after the ï¬rst activation; T4:after 2â€¯×â€¯1/4 activation; T5:after 7â€¯×â€¯1/4 activation; T6:after 14â€¯×â€¯1/4 activation; T7:retention period on the 1â€¯st month; and T8:retention period on the 3rd month]. Although the levels of IL1-β, NO, and PD increased signiï¬cantly from T1 to T2, the GI, BOP%, and PI remained unchanged throughout treatment. GCF volume at buccal and palatal surfaces increased signiï¬cantly from T1 to T4, T6, T7, and T8. The parameters in GCF and TAC levels were not only higher at palatal side in comparison with buccal, but also TOS levels increased at both buccal and palatal sides. In this study, the differences of oxidative status and IL-1β levels during RME treatment could be attributable to orthopedic effect of the heavy forces on maxilla and minimal orthodontic forces on teeth applied by the RME apparatus.
