Abstract:
After a stroke the mouth can become a very unhealthy place and act as a reservoir for opportunistic oral microbiota. The growth and proliferation of opportunistic microbiota can not only result in deteriorating oral health status but lead to systemic upsets with life-threatening consequences and impact for stroke rehabilitation. Maintaining oral hygiene in the initial periods following stroke is problematic as often stroke survivors experience loss of motor function of the limbs required for oral self-care. Patients with stroke are commonly encountered difficulties in swallowing and, therefore, are at a greater risk of aspiration pneumonia from microbiota originating in the oral cavity. Thus good oral hygiene for stroke survivors is of key importance to potential lifesaving effects. Patients require specific information and assistance on the oral care to enable them to maintain good oral hygiene. Hence, empowerment of caregivers is crucial and important. Caregivers may need to be vigilant of this and to assist patients with stroke to maintain oral hygiene so as to prevent not only oral diseases that further compromise their rehabilitation, but also to prevent life threatening events. Improved in oral health knowledge, attitude and behaviors of the caregivers may provide better delivery of oral health care to patients. Hence helps to improve the oral health conditions in patients. This presentation will explore the gap present in implementing oral health care and the importance of caregivers in maintaining good oral hygiene to patients with stroke.

Title: Customized topography with tailored porosity control of composite 3D scaffold for enhanced bone tissue engineering
Time :
Biography:
Mehdi A Ebrahimi is a graduate of Oral and Maxillofacial Surgery from Prince of Songkla University (Thailand). Beside his clinical interest in Maxillofacial Reconstruction and Traumatology, he started his research activities on biomaterials with special focus on biphasic bioceramics in 2010. He presented his works at different local and international conferences and published several papers in peer reviewed journals. He is currently working as a Researcher and PhD candidate at Prince Philip Dental Hospital (Hong Kong). His recent research focus is on development of novel hybrid nano-bioceramics with incorporation of collagen as a potential carrier of signaling molecules for enhanced bone regeneration.
Abstract:
Bioceramic biomaterials provide excellent support for bone tissue engineering, yet there are many shortcomings in physicochemical properties to be improved. Surface topographical features ranging from nano to macro are of great importance in determining the particular cellular responses toward the scaffold. There have been many attempts in the literature to tailor the porosity in order to modify the surface topography. It is known that pore dimension, geometry and overall porosity and interconnectivity have significant impact on cellular attachment, migration and communication. However, the control of porosity parameters in 3D scaffold structure is a challenging task. Different porogens to better customize the porosity have been studied but the challenges are difficult control over pore size and the need to remove porogens to avoid cytotoxic effects. Here, we introduce a novel technique by using non-toxic non-ionic surfactant (Tween) as porogens to aid in customizing surface topography by modifying porosity features of composite collagen-HA scaffolds during lyophilization process. Four different ratios of Tween (0, 10, 20, 30 wt%) and two ratios of collagen-HA (85/15 and 92/8 wt%) along with a controlled quenching rate allowed production of a range of porosities (> 90%), pore sizes (≤ 500 nm and 100-300 µm) with high interconnectivity. It is assumed that a range of pore size and geometry will provide a suitable topographical feature that may better support vascularization and cells communication. This will be of great advantages over conventional scaffolds in supporting cellular interactions and improving cellular behaviors for enhanced bone tissue engineering.

Abstract:
Implant dentistry is a merger of different disciplines of dentistry like oral surgery, prosthodontics, periodontics, radiology, orthodontics and endodontics. Surgery and prosthetic rehabilitation play the key part of treatment. There are situations where other disciplines play an important role. When remaining teeth is involved in rehabilitation along with implants or where aesthetic concern comes into play often procedures like crown lengthening, post core and even Lasers become applicable. Three case reports are discussed where an interdisciplinary involvement of dental treatments was deemed beneficial to the patients in achieving a successful outcome.

She has now been served as Editorial Advisory Board Committee for Journal of Pediatric Dentistry (JPD) and Scientific Paper Reviewer for Journal of the Dental Association of Thailand (JDAT).
Abstract:
Revolutions in pediatric dental caries management will require a paradigm shift in the way professions approach prevention and management of the disease. Prevention of dental caries has relied mainly upon parental and patient cooperation and significant life style changes that are at best difficult to implement and maintain or at worst ignored. The paradigm shift in pediatric dental caries management demands that clinicians redirect their energies and emphasis from the "surgical" approach to dental caries to a "medical" strategy and therapeutic intervention including use of antimicrobials to reduce caries producing-bacteria and innovative materials for re-mineralization. The revolutions will require the development of non-surgical strategies as well as biochemical approaches on the essentials of the paradigm shift. This presentation will provide interesting perspectives on unconventional approaches to dental caries management and novel ideas to incorporate into pediatric practices for new approaches to dental caries management.

Abstract:
Purpose: To compare on effects of different surface treatments, such as acid etched and Laser treatments of titanium surfaces especially new alternatives on the adhesive strength between resin and titanium surfaces. Methods: Sixty titanium grooved disks (makro etched) were prepared and they were seperated into five groups as follows: 1) No treatment-control group; 2) Sandblasted group with aluminium oxide; 3) Tribochemical procedure group in the laboratory; 4) Tribochemical procedure group in the clinically; 5) Nd:YAG Laser-irradiated group. The topographic patterns were observed by scanning electron microscopy. After these tests, resin cement was applied to the titanium surfaces. Shear bond test was performed via a universal testing machine at a crosshead speed of 0.5 mm/minute. In addition, the correlation between the surface roughness and bond strength was checked using Spearman correlation test (The mean difference is significant at the 0.05 level). Results: The highest mean shear bond strength was recorded with Tribochemical procedure group in the laboratory (rocatec plus-silan) 15.701±2.62) and the lowest with the control group (5.23±2.49 MPa). Conclusion: All of the surface treatment methods that were used in present study increased the bond strength between resin and titanium surface.

Title: The use of piezoelectric surgery in Oral and Maxillofacial Surgery
Biography:
Berkay Tolga Suer has completed his Graduate degree from Aegean University and PhD degree from Gulhane Military Medical Academy (GATA) at Ankara. He is a Clinical Associate Professor of the Oral and Maxillofacial Surgery department at GATA Haydarpasa Teaching Hospital in Istanbul. He has published more than 30 papers in reputed journals.
Abstract:
Piezoelectric surgery device or ultrasonic surgery device was originally developed for the atraumatic cutting of bone by way of ultrasonic vibrations and as an alternative to the mechanical and electrical instruments that are used in conventional oral surgery. Even though piezoelectric bone surgery is a relatively new alternative for bone-related procedures in oral and maxillofacial surgery, over the past two decades, increasing amount of literature has shown the application of piezosurgery within dental surgery, implantology and maxillofacial surgery. Recent publications have also shown the benefits of their use in craniofacial surgery, plastic and reconstructive surgery, head and neck surgery, neurosurgery, ophthalmology, traumatology, and orthopaedics. Key features of piezosurgery include the selective cutting of bone without damaging the adjacent soft tissue (e.g. vessels, nerves or mucosa), providing a clear visibility in the operating field by the way of pressurized irrigation and cavitation phenomenon, as well as cutting with micron sensitivity without the generation of heat. According the literature large initial costs of this innovative tool could be considered one of the disadvantages. The other main disadvantage would be the increased operation times when compared with conventional techniques in Oral and Maxillofacial procedures. The author of this presentation describe the current status of the application of piezosurgery within oral and maxillofacial surgery facilitated by the use of clinical case examples and argue that piezosurgery should take a place in the surgical armamentarium of a surgeon that deals with bone procedures.

Abstract:
The expanding role of endodontics into different phases of dental treatment is illustrated by the awareness of its relationship with orthodontics. Orthodontic treatment is done for gaining esthetic appearance for the patient & for the establishment of proper occlusion. However, there is a paucity of information on the concise relationship between endodontics and orthodontics during treatment planning decisions. This relationship ranges from effects on the pulp and potential for root resorption from orthodontic treatment to the clinical management of teeth requiring integrated endodontic and orthodontic treatment. This paper presentation will address the consequences of tooth movement on the pulp and preventive measures to be taken to maintain its vitality. Other areas such as comparison of various endodontic procedures on teeth movement and effects of teeth movement on apical seal will also be covered. Towards its end, the presentation will cover the treatment planning with combined orthodontic-endodontic therapy, necessary to gain the desired endodontic result and ascertain better prognosis.

She is a member of American Academy of Pediatric Dentistry, European Academy of Pediatric Dentistry and Arabian Academy of Pediatric Dentistry. She has experience in treatment of special health care needs in children.
Abstract:
Paediatric venous access causes unnecessary anxiety and pain in children and, in turn, can have detrimental consequences. Behavioural approaches to paediatric venous access distress management can be organized temporally. Specifically, preparation before the procedure includes providing children with sensory and procedural information in an age-appropriate manner and providing training in coping skills. It is important to consider the timing, format, and content of the approach to provide optimal preparation for the unique circumstances of the individual patient. In addition to the child patient, preparing parents and teaching them which specific behaviours might be most helpful to their child should prove valuable to both patient and parents. During the procedure, there are benefits to providing secure and comfortable positioning. In addition, researchers recommend that adults encourage children to cope and actively engage children in distracting activities. For infants, there is support for the distress-mitigation properties of swaddling, skin-to-skin contact, breastfeeding, and sucrose. After venous access, distraction and encouragement of coping should speed recovery. In sum, research in behavioural approaches to paediatric pain management has provided recommendations for minimizing children's anxiety and pain associated with venous access.

He is currently working as an Assistant Professor in the Department of Conservative Dentistry and Endodontics, at the Nair Hospital Dental College, Mumbai.
Abstract:
One of the main objectives of endodontic treatment is the thorough preparation of the root canal system and proper obturation for obtaining a three-dimensional seal. To achieve this goal, clinicians must have a comprehensive knowledge of the normal anatomy of the relevant root canal system and its common variations. Cross-sectional root canal configurations have been classified as round, oval, long oval, flattened, or irregular. The oval shaped canals should have a different approach regarding management compared with normal root canal configurations. The recognition of oval configurations determines that a different approach be applied in cleaning, shaping and obturation. It is difficult to prepare root canals with oval cross-sections since their irregular shape make steady contact of the instruments with the canal walls a challenge. Circumferential filing movements allow improved contact with the canal wall, although this method does not always guarantee the preparation of the entire root canal. The aim of this presentation is to address the definition, prevalence, and treatment protocols for oval shaped canals.

Abstract:
The rehabilitation of an edentulous space aims to return esthetics, function, comfort, phonetics and health to the patient. Certain clinical cases of oral rehabilitation require interdisciplinary treatment with the need for orthodontic treatment, endodontics, and prosthetically driven implant placements. Multi -disciplinary planning based on diagnostic wax setup casts to determine exact implant location and orientation in line with future orthodontic tooth displacements and prosthetic implant crown restorations is the most important step in the overall treatment planning. This lecture describes many such case series of rehabilitation involving orthodontics, surgery, implant insertion and aesthetic restorative dentistry, with an implant-supported prosthesis approach.

Time :
Biography:
Sara Kaveh has taken her DDS from Mashhad Dental School, Iran and MS from Isfahan Dental School Iran. She is the Professor of Operative Dentistry in Semnan Dental School.
Abstract:
This in vitro experimental study was conducted on 96 sound primary teeth randomly divided into 8 groups (n=12). Four groups were demineralized and the rest remained sound. All the specimens were subjected to pH cycling. Then, GC-Tooth Mousse was applied on their surfaces. Composite resin was bonded using Clearfil SE Bond self-etch or Single Bond total-etch bonding systems. The bond strength of the specimens was measured by an Instron machine and the mode of fracture was assessed by a stereomicroscope. Data were analyzed by one-way and two-way ANOVA and chi-square test. In the total-etch system, the bond strength of demineralized group was significantly higher than that of sound group (p=0.009). This difference in self-etch system was not significant (p=0.928). The CPP-ACP remineralizing agent decreased the bond strength in total-etch and increased the bond strength in self-etch group (p=0.032 and p=0.018, respectively). No difference was observed in the mode of fracture of the two bonding systems. GC Tooth Mousse decreased the bond strength to composite in total-etch and increased it in self-etch group. Higher bond strength to composite can be achieved in teeth with white spot lesions (WSLs) when total-etch system is used.

She has presented her work in national and international conferences and has published many scientific papers in high quality impact journals. She has over 7 years of teaching experience and is also the author of the upcoming book “Optical Spectroscopic techniques in the management of periodontitis”.
Abstract:
Photodynamic therapy (PDT) is a modern approach in dentistry where light of an appropriate wavelength is used in the presence of a specific photosensitizer (PS) to eradicate target cells selectively. Although PDT is more widely known for its application in the treatment of neoplasms, PDT shows great potential in the treatment of periodontitis. Treatment of patients with periodontitis of varying extent and severity can be often challenging and difficult. Although scaling and root planing still remains to be the gold standard for the non-surgical treatment of periodontal disease, however, it has been noticed that in some cases, adjuctive treatment modalities are required to suppress periodontal pathogens and augment the effect of conventional mechanical treatment. Therefore, photodynamic therapy (PDT) has been suggested as an alternative treatment modality in managing periodontitis. Various clinical trials have been conducted to evaluate the effects of PDT as an adjunct in the management of chronic and aggressive periodontitis patients. While there is still inconclusive data regarding a definitive benefit for PDT along with SRP in the treatment of periodontitis, its noteworthy that several clinical trials have shown additional clinical, microbiological, immunological and patient-based benefits when PDT and SRP were given in combination to patients with periodontitis. This presentation is an evidence-based approach to summarize the results of the available literature for clinical protocol for application of photodynamic therapy. It is intended to aid the clinicians and academicians in making evidence-based treatment decisions regarding PDT as a nonsurgical treatment modality in management of periodontal diseases.

Abstract:
Speech and language development is a useful indicator of a child’s overall development and cognitive ability. Identification of children at a risk for developmental delay or related problems may lead to intervention and assistance at a young age, when the chances for improvement are the best. Pediatric dentists are primarily involved in treating young children and communication with the child is essential for co-operation and effective treatment. During the process of communicating with the child any evidence of abnormal speech or deviant or delayed language skills can be identified by the pediatric dentist. Thus, screening children for speech and language delay can be integrated into routine clinical practice, followed by referrals for thorough diagnostic evaluation and appropriate intervention

Abstract:
Thousands quit smoking every day - by dying ~author unknown tobacco and the tobacco products affects human in all the possible ways as children who are exposed to tobacco smoke on daily basis grow up with more than triple the risk of lung cancer later in life compared to those who grow up in smokeless environment, personal appearance such as premature aging, wrinkling, greying, wasted appearance, delayed wound healing, and delaying in recovery and increased complications are recorded not only on health but also economical fronts are affected when it comes to being addictive to the tobacco products. All phases of tobacco production have the potential to contribute to climate change from farming to curing the leaf and manufacturing process. many studies are being conducted to study the impact of tobacco on ecological aspect, devastating effects on human health, chemical wastes in the process of manufacturing of tobacco products and the enormous amounts of litter caused by cigarette butts which are not bi-degradable the life cycle of cigarette takes a heavy toll on environment from growing the tobacco plant to the disposal of butts. The ecological impacts of tobacco are over shadowed by its devastating effects on human health, they are nevertheless considered as a cause of cancer. Many attempts are being made to reassess the carcinogenicity of several compounds including tobacco, though the lancet oncology concluded that smoking is cause of at least 15 types of cancer. This is to heave a light on the issue we always talk and alarmed about and need to act before the devil gulps the humans, gorgeous mother earth and the hard earned money of each individual who enjoys the transient smoky cloud of evil tobacco that is tobacco vs. health environment and economics.

Title: The association between the frontal sinus morphological variations and the cervical vertebral maturation for the assessment of skeletal maturity
Time :
Biography:
Hafiz Taha Mahmood is a Resident of Orthodontics at Dental Section, Department of Surgery, The Aga Khan University Hospital, Karachi, Pakistan.
Abstract:
Introduction: The assessment of skeletal maturity is important for planning dentofacial orthopedics or orthognathic surgery for the treatment of different skeletal malocclusions. Cervical vertebral maturation is widely used method to evaluate skeletal maturity of patients undergoing orthodontic treatment. In the past decade, another method is being proposed which is based on frontal sinus morphology. So, the aim of this study is to evaluate the association between frontal sinus morphological variations and cervical vertebral maturation for the assessment of skeletal maturity. Method: Lateral cephalograms of 252 subjects aged 8-21 years were collected from the dental clinics of AKUH. The sample was divided into six groups based on cervical vertebral maturation stages. The frontal sinus index was calculated by dividing frontal sinus height and width and the cervical vertebral maturation stages were evaluated on the same radiograph. Data were analyzed using SPSS (version 19). Kruskal-Wallis test was applied to compare frontal sinus index at different cervical stages and Post hoc Dunnett t3 test was applied to compare frontal sinus index between adjacent cervical stage intervals in males and females. A p-value of ≤0.05 was considered as statistically significant. Results: The frontal sinus height and width were significantly associated with the individual cervical vertebral maturation stages in males and females. However, frontal sinus index wasn’t significantly associated with the individual cervical vertebral maturation stages in males and females. Conclusion: Frontal sinus index cannot differentiate between pre-pubertal, pubertal and post-pubertal adolescent growth stages therefore; it cannot be used as a reliable maturity indicator.

Biography:
Batool Ali has completed her Bachelor of Dental Surgery from the Karachi Medical & Dental College which is associated with Karachi University and is currently pursuing her Post-graduate studies in Orthodontics at the Aga Khan University, Karachi, Pakistan. She is a final year resident in the program of Orthodontics. Over the last few years she has published 4 papers in reputed journals.
Abstract:
The palatal rugae have been used as a reference landmark and identification marker by orthodontists and the forensic analysts, respectively. However, the reliability of palatal rugae as a forensic marker remains questionable once an individual is subjected to orthodontic treatment. This study aims at evaluating the changes in the rugae pattern after non-extraction, extraction and maxillary expansion orthodontic treatment. The lengths and shapes of palatal rugae were evaluated on the pre-treatment and post-treatment dental casts of 168 subjects using Thomas and Kotze classification. Extraction treatment significantly reduced the second and third rugae lengths (p<0.05); whereas, the third rugae length was significantly increased after palatal expansion (p<0.05). The shape of rugae remained consistent in all the study groups which may be used as a reliable forensic marker in subjects undergoing orthodontic treatment. However, the use of the lengths of palatal rugae in forensic odontology must be made with caution.

He is Chief Resident in the program of Orthodontics. Over the last few years, he has published 7 papers in reputed journals and has been serving as reviewer for several journals of good repute.
Abstract:
Treatment with the growth modification appliances is only successful if commenced at the right stage of adolescent growth spurt. Variations in the timing of adolescent growth spurt can affect the success of the treatment. The aim of this study was to compare the mean age of adolescent growth spurt among children with three skeletal classes. A cross-sectional study was conducted on the lateral cephalograms of 440 children (203 boys, 237 girls) aged 9-17 years. Subjects were categorized into three skeletal classes (Class I=187, Class II=169, Class III=84) according to the sagittal relationship between maxilla and mandible. The cervical vertebral maturation stages were recorded using Baccetti’s method. The mean age at each cervical stage was compared between two genders and among three malocclusion using Mann-Whitney U and Kruskal-Wallis tests, respectively. The results of the study showed that the pubertal growth peak occurred on average 1.5 years earlier in girls than boys. The mean difference in the age of adolescent growth spurt between Class I and II girls was of 7.5 months (p=0.026) and between Class I and III boys was of 10.5 months (p=0.022). All boys older than 16.5 years and girls older than 16.0 years were found to be in cervical stage 6. However, timing of completion of the adolescent growth spurt is comparable among three skeletal classes.
