Abstract:
Objective: Dentists are exposed to musculoskeletal disorders, which are related to the work environments. Th e objective of this survey is to determine the prevalence of MSD among dentists in Lebanon. Materials & Methods: A questionnaire was distributed by the authors to the participants during the congress of the Lebanese Dental Association in September 2013. Th e recorded data was analyzed with SPSS 20. P-value<0.05 was considered to be statistically signifi cant.
Results: 219 dental practitioners participated in the study of which 92.7% suff ered from MSD and 40% had a prevalence of at least one MSD symptom over the past 12 months. Most common areas aff ected by MSD in order of magnitude were low back (61.8%), neck (51.5%), shoulders (39.5), fi ngers (14.1%), wrist (11.8%), and elbow (8.6%). Neck pain was related to the working hours per day. Females had a higher frequency than males in the most area. Permanent pain is inversely proportional to the physical activity. Conclusions: High prevalence of MSD exists among our dental practitioners aff ecting the daily practice. Further studies are needed to identify the specifi c risk factors for MSD so as to introduce eff ective remedial measures.
Zubaida Al Karaawi
Prince Sultan Medical Military City, Saudi Arabia
Title: Moderate and Deep Sedation Experience in Paediatric Dental Patients in Riyadh
Time : 11:50-12:20
Biography:
Zubaida Al Karaawi has completed her Master’s degree in 1999 in Pediatric Dentistry and PhD in Clinical Dentistry from UCL, London in 2004. She had completed six months course and passed the examination in Sedation and Pain Management from the Eastman Dental Institute in 2006. She is a Consultant in Pediatric Dentistry and teaching in the Saudi Board Program (Pediatric Dentistry) at Prince Sultan Medical Military City in Riyadh. She has published several papers in reputed journals.
Abstract:
The prevalence of dental caries among Saudi children is greater than 80%. Changing in the lifestyle of the Saudi population in the past decades is associated with high prevalence of dental caries such as an increase in the consumption of sugary food, carbonated drinks and lack of awareness towards proper oral health maintenance. Many of those children attended dental clinic if they have dental pain or dental abscess that makes treatment on dental chair is challenging for the dentist. Th erefore, many of those young children receive dental treatment under sedation or general anesthesia (GA). Oral sedation in pediatric dental clinic was initiated more than ten years ago in Prince Sultan Medical Military City (PSMMC) in Riyadh. Oral sedation was provided as single drug and monitored by the pedodontist. All patients received sedation were healthy children (ASA1). Sedative drugs were either midazolam 0.3-0.5mg/ kg or Vallergan Forte (alimemazine tartrate) 1-2 mg/kg. Th ough for the safety of the patients, the hospital policy has changed and oral sedation (midazolam) was provided and monitored only by the anesthesiologist in the dental chair for four years. Patient safety was still a great concern for the hospital administrationand it was decided to follow same protocol of sedation in the dental day case operating room as the area is fully equipped to deal with any emergencies and possibility to administer GA. In addition, the recovery area has advanced monitoring machines and qualifi ed recovery nurses. Unfortunately,dental treatment provided was minimal as midazolam in its own was not eff ective enough and children were fully awake and uncooperative.Th erefore, a new protocol has been approved by the department of anesthesia to administer multiple sedative drugs as a cocktail of IM or IV midazolam, ketamine and atropine (doses are adjusted according to the patient’s body weight). IV line is applied for all patients treated under sedation for IV fluids and for immediate interaction in case of emergencies. All patients must have pretreatment assessment and full blood profi le few days before the treatment. Patients are required to fast 6-8 hours before the operation. Patients who received multiple sedative drugs are usually in state of moderate to deep sedation and hence they require longer time for recovery similar to that for the GA. Pedodontists who treat patients under sedation, must have passed the test of the sedation course provided by the hospital. In our sedation protocol, showed successful dental treatment without any complications and reduce the need for GA. However, dental sedation is provided only inselective cases and not an alternative to dental treatment on dental chair with behavior management or treatment under GA.

Abstract:
Periodontitis is a group of infl ammatory diseases that aff ect the connective tissue attachment and supporting alveolar bone around the teeth. Periodontal diagnostic procedures should provide information to the clinician regarding the type of periodontal disease present, the location and the severity of the disease. Th e present periodontal diagnostic parameters incudes: probing depth, clinical attachment level, plaque index and radiographs. Th ough these diagnostic parameters are easy to use, non-invasive and cost effective, they do not measure the periodontal risk and the current disease status. Today, biomarkers play a great role in diagnosis of periodontal disease and disease monitoring. Th is presentation aims to focus light on this futuristic diagnosis of periodontal diseases using biomarkers.

Title: Oestrogen receptor (ER) expression and activity during osteogenic differentiation of dental pulp cells
Time : 12:50-13:20
Biography:
Dr. Aishah Alhodhodi is professor of University of Leeds, UK
Abstract:
Oestradiol (E2) maintains skeletal tissue integrity and significantly enhances osteogenic potency of mesenchymal stem cells. The activity of E2 is regulated both acutely and chronically through the interaction with high affinity oestrogen receptors (ERs). There is very little literature on the expression and activity of ER isoforms in dental pulp tissue and their regulation during osteogenesis of dental pulp cells. The aim of this study is to explore the expression and regulation of ER subtypes, ERα and ERβ in human dental pulp cells during their osteogenic differentiation. Human dental pulp cells derived from healthy female donors aged 20-24 yrs. were cultured. Cells were differentiated down an osteogenic lineage or cultured under basal conditions to provide controls. The cells were harvested on days 7, 14 and 21 for ER profiling by RT-PCR and Western blot. The results showed that both ERα and ERβ mRNAs were expressed in human dental pulp cells. However, only ER-β was up regulated during osteogenic induction. ERβ protein was also detected by Western blot with ERα showing only faint reactivity. We suggest that ERβ may be the principal isoform expressed in human dental pulp cells and may actively participate in the osteogenic differentiation process of these cells.

Title: Marginal Gap Evaluation of Metal Onlay and Resin Nano Ceramic (RNC) (LAVA â„¢ Ultimate CAD/CAM Blocks) Onlays
Time : 14:30-15:00
Biography:
Wan Zaripah Wan Bakar is a Senior Lecturer and Consultant Prosthodontist at University Sains Malaysia, Malaysia. She has completed her Doctorate in Clinical Dentistry (Prosthodontics) at University of Adelaide, Australia in 2006. She has completed her Post-doctoral Research Fellow program from University of Texas Health Science Center at San Antonio (UTHSCSA), USA in 2013. She has published more than 30 articles.
Abstract:
This study is to assess and compare the marginal gap of metal based on onlay and nano resin ceramic (Lava™ Ultimate block) onlay. The study was carried out in vitro on two extracted lower sound human mandibular molars. One extracted tooth was prepared to receive a metal onlay and another one for RNC (Lava TM Ultimate) onlay, which was fabricated using CAD/CAM technology. After fabrication of 12 metal and 12 ceramic onlays, marginal analysis was done under Leica stereomicroscope (Leica, Germany). The gapwidth was measured at 10 defi ned landmarks which include three points on the buccal and lingual surfaces and two points on the mesial and distal surfaces. Mann–Whitney Test was used for statistical analysis (P=0.05). It was observed that overall RNC onlays (Lava™ Ultimate block) showed signifi cant lower marginal gap measured with the exception of the landmark 5 and 6 at disto-lingual site. Landmarks 7 at mid-lingual site showed no signifi cant difference between both groups. It was concluded that, the marginal gap observed were all within the clinically acceptable limit (120 μm). Based on the results obtained, the resin nano ceramic onlays (Lava™ Ultimate block) CAD/CAM can be one of alternative materials for the metal onlay in term of marginal gap.

Title: “Gain Without Painâ€: Evaluating Preemptive Analgesic Effects of Dextrometharphan in Reducing Postoperative Pain
Time : 15:00-15:30
Biography:
Kruthi Nanduri has completed Master’s in Oral & Maxillofacial Surgery from DR. NTR University of Health Sciences, India. She worked as an Assistant Professor in Sibar Institute of Dental Sciences, India. She is presently working as a Consultant Maxillofacial Surgeon in Apollo hospitals, Mysore, India. She has several publications to her credit in various journals of national and international repute. Her areas of interest include maxillofacial trauma, pathology and aesthetic surgery.
Abstract:
Post-operative pain is the most common complication following any surgical procedure. Commonly performed minor oral surgical procedures like surgical removal of impacted third molars are associated with considerable amount of postoperative pain as incision & subsequent inflammatory response cause central sensitization and increased conduction of nociceptive impulses to central nervous system which not only increases the pain but also causes non painful stimuli to be perceived as pain. NMDA receptors play a role in this increased central sensitization. Pre-emptive analgesia is a treatment that is initiated before the surgical procedure in order to reduce this sensitization. Hence, we have undertaken a prospective study to evaluate the preemptive analgesic effects of Dextromethorphan, an NMDA receptor antagonist in reducing the postoperative pain following surgical removal of bilaterally impacted mandibular third molars.

Title: Role of Multidetector Computed Tomography in assessment of Fibro-osseous lesions of craniofacial complex
Time : 15:30-16:00
Biography:
Dareen Mohamed Abdel Hameed Khattab has studied Medicine at Alexandria University, Egypt. She has received her Master’s degree in Radio Diagnosis and Interventional Radiology from Alexandria University, Egypt, 2014. She is a member-in-training in RSNA, a Reviewer at the Biological Sciences Journal. She has fi ve years of experience in radio-diagnosis and is a Radiology Specialist at Dar Ashaa, Alex, Egypt. She is the author of a book “Utility of MDCT in fi bro-osseous lesions of craniofacial complex” published by Lambert Academic Publishing, available online since Feb. 2015.
Abstract:
Fibro-osseous lesions of the craniofacial bones comprise a diverse group of pathologic conditions that includes developmental lesions, reactive or dysplastic diseases, and neo-plasms. They share many similar histo-pathological features with other nonfibro-osseous disease processes that develop within the jaw bones. Thus a definitive diagnosis offi bro-osseous lesions (FOLs) requires a correlation of the histological features with the clinical, radiographic and intra-operative fi ndings. Th is study highlights the importance of the role of multi-detector row CT images, in assessment offi bro-osseous lesions in craniofacial complex in patients with known fi bro-osseous lesions, facial disfigurement and facial swelling. Multidetector computed tomography (MDCT) including reformations better delineate craniofacial complex anatomy than do single detector row CT images. It becomes possible to depict the complete path of complex structures. It is valuable in diagnosis and in guiding the surgical interventions by allowing pre-operative delineation of craniofacial complex anatomy. Th e proximity of the various components is best appreciated when the area is viewed inaxial and coronal sections and different reconstructive methods using sub-millimetric thickness. MDCT is a powerful diagnostic and illustrative tool that will narrow the gap between the radiologists and the surgeons.

He is also a Clinical Supervisor of the Advanced German Board students in United Arab Emirates. He is a member of the DGZI and GBOI.
Abstract:
This technique is used to minimize the surgical extraction complications at vital areas and will help us to preserve the bone from being lost during extraction. And this also makes it end in a smoother and easier extraction which will help us to minimize the post operative pain and bleeding after the surgery. This simple idea which turned into a technique will be explained easily in a power point slide show, which will show how to handle cases close to vital areas, especially wisdom teeth which are in close or direct contact with the inferior alveolar canal. Th e technique is also supported with a clinical case, which will help us to go through all the techniques including the treatment plans till the extraction. The clinical case is supported with Cone Beam Computed Tomography (CBCT) and panoramic technique before and aft er to show us the exact benefit of this technique. And it will also show how it can be used by the dentists to handle such difficult extraction cases safely without any doubt or fear to hurt their patients since; this idea is so simple and applicable.

Title: Is periodontal disease a risk factor for developing Alzheimer’s disease?
Time : 10:00-10:30
Biography:
Sim K Singhrao has gained her PhD from Cardiff University, UK. She did her Post-doctoral training from Cardiff University School of Medicine and then from the School of Dentistry. She is currently a Senior Research Fellow at the University of Central Lancashire, exploring the causative relationship of periodontitis and Alzheimer’s disease. She has published more than 60 papers in peer-reviewed journals and 4 book chapters. She is currently serving as an Editorial Board Member for Journal of Alzheimer’s Disease.
Abstract:
Alzheimer’s disease (AD) is a neurodegenerative condition that results in a long-term devastating emotional/psychological impact on their loved ones. The neuropathological hallmarks of AD are the deposition of copious amounts of amyloid beta (Aβ) and hyperphosphorylated tau protein coated neurofi brillary tangles in the brain. For decades, the role of the innate immune system in the etiology of AD was considered less important but the recently discovered infl ammatory genes by Genome-Wide association studies driving infl ammation in this disease has changed this view. Innate immune infl ammatory activity in the AD brain can result from the pathological hallmark Aβ protein as well as from specifi c peripheral microbial infections including the sub-gingival bacterial biofi lms. Oral spirochetes and Porphyromonas gingivalis components such as lipopolysaccharide (LPS), peptidoglycan and genomic DNA have all been detected in the brains of AD following autopsy. The oral pathobionts elicit weak immunostimulatory activity as a consequence of their immune evasion strategies, which aid their survival in the host. The aim of this presentation is to, disseminate new knowledge in the ever expandingfield of dentistry with experimental evidence from human AD brains and from experimental models of periodontitis in the apolipoprotein E(APOE) gene knockout mice. Th e possible contribution, specifi cally of the oral pathobionts P. gingivalis playing a role in infl uencing the development, and progression of AD infl ammatory pathology will be highlighted.

Abstract:
In the era of novel cancer treatments, both cancer doctors and dentists are observing drug related oral toxicities. Hence, awareness and multidisciplinary approach is necessary to improve the management of the patients. Th e oral mucositis which is secondary to chemotherapy, and especially in high-dose chemotherapy during the transplant setting, has now become the focus of several studies. Doctors are also well aware of acute and long term toxicities due to radiation of head and neck. Starting from 2003, Osteonecrosis of the jaw (ONJ) related to the administration of bisphosphonates represented a new challenge in the cancer care. Due to the recognition of the risk and the introduction of preventive strategies and combined therapeutic approaches, the number of new cases and the most severe consequences have become limited. More recently, the introduction of novel anti-cancer drugs and antiresorptive agents highlighted, oral complications with some similarities and some new aspects compared with the chemotherapy-induced mucositis, and bisphosphonate related ONJ. In particular, target therapies like everolimus, an m-TOR inhibitor, and EGFR-inhibitors induce mucosal lesions, ranging from mucositis to aphthous-like ulcers. Whereas, the novel antiresorptive agent denosumab, an anti-RANKL moncolonal antibody, and antiangiogenetic drugs have demonstrated a potential risk in inducing ONJ, increasing the number of drugs involved in bone damage of the mandible and maxilla. In the current presentation, we will present an up-date of the oral complications in the era of novel cancer treatments in order to inform the specialists, promote a multidisciplinary approach and improve patients care.

He is treating so many cases of TMJ disorder and gummy smile by Botox, besides participating in many international conferences as a Lecturer in many countries like USA, Germany, Jordan, Taiwan, Hong Kong and many Arab countries.
Abstract:
I believe that, an orthodontist is not only a specialist dentist; he must have knowledge and interest in art, as dentistry is not about teeth treatment but also aesthetic of the face. In some clinical cases, in our daily practice we might face bone defi ciency to replace missing teeth with dental implants instead of doing second surgery and bone augmentation. We can be more conservative depending on orthodontic means such as; extrusion of hopeless teeth, in other cases, can be used in mini implants to adjust the complicated orthodontic cases and surgical cases such as skeletal open bite or interocclusal space defi ciency. This lecture is for all the implantologists, orthodontists and general practitioners. In this lecture, I will talk about clinical cases to show the interrelation between ortho, implant, aesthetic dentistry and aesthetic medicine for solving clinical cases with no surgery. It’s for specialist dentist and general practitioner. Cases in the lecture will cover: 1) Extrusion of hopeless anterior centrals to correct bone level before replacing them with dental implant instead of bone augmentation; 2) to gain more interocclussal space by intrusion of opposite posterior teeth; 3) to correct skeletal open bite by using mini implant instead of orthognathic surgery; 4) using mini implant to align tilted teeth to provide space for implant or bridge and 5) gum smile treatment by mini implant and Botox beside some cases about aesthetic dentistry.

Time : 12:45-13:15
Biography:
Ahmed ElSebaai is currently working as Professor of Department of Pediatric Dentistry at Mansoura University-Mansoura- Egypt.
Abstract:
Aim: Th e aim of this study was to evaluate the effect of resin infiltrant on white spot lesions compared to adhesive resin.
Methods: Artificial white spot lesions were created on the labial surfaces of 65 anterior permanent teeth. 31 teeth (Group A white lesion) were divided into three groups according to treatment applied: control A1, ICON A2 and adhesive A3. Th e remaining 34 teeth were immersed in a staining solution. The stained lesions were bleached (Group B) then divided to three groups: control B1, ICON bleached B2 and adhesive resin bleached B3. Th e teeth were photographed at three stages and photos were analyzed to evaluate the color diff erence ΔE between the lesion area and sound enamel before and aft er treatment using image soft ware analysis. Th en, Vickers micro-hardness test was done for the whole teeth aft er treatment.
Results: The ICON A2 group showed a highly significant color improvement (P=<0.0001) compared to the other groups. The other test groups also showed significant color improvement but not as the ICON group. Icon group A2 showed the highest surface microhardness.
Conclusion: Resin infiltrant is an eff ective microinvasive approach in masking white spot lesions much more than adhesive resin.

Abstract:
Diabetes mellitus is known to cause micro vascular and possibly macro vascular completions. Similarly Extensive periodontal disease is associated with increased C- reactive protein (CRP) levels in otherwise healthy, middle aged adults. Periodontal disease seems to influence the occurrence and the severity of coronary artery disease and increases the risk of heart attack or stroke. Different studies proposes two hypotheses, one is that periodontal pathogens could enter the bloodstream, invaded blood vessel walls and ultimately cause atherosclerosis. Another hypothesis shows that periodontal infections can be correlated with increased plasma levels of inflammation such as C-reactive protein. Indeed the periodontal signs & symptoms are now recognized as the sixth complication of diabetes. CRP predicts not only heart disease, but also the risk of developing type 2 diabetes. Individuals with CRP levels greater than 3 mg/L have a risk of getting diabetes 4 to 6 times higher than individuals with lower levels of CRP. Moderate elevation of CRP has been found to be a predictor of increased risk for CVD. Elevated CRP levels in periodontal patients have been reported by several groups. In this study, we examined whether CRP plasma are increased in periodontitis.
