Abstract:

We are using restorative dental materials to restore or help in restoring missing, diseased, and traumatized teeth, tooth structures and tissues. Dental materials and, in general, biomaterials have been initialized and developed at dental schools. Dentists are the only authorized end users of dental biomaterials. Novel, innovative emerging dental materials are at the front position of new technologies ‎in dentistry. Dentistry has been moving rapidly toward adhesive and noninvasive direction, the so-called conservative dentistry. Dental materials science is an integral, multidisciplinary domain in dental sciences. Materials in dentistry are predominantly synthetic, such as resin composites, silver amalgam, dental cements etc. Restorative dental materials can be classified according to the principles of direct application ‎as a) direct restorative materials and b) indirect restorative materials. Direct restorative materials ‎such as resin composites, silver dental amalgam, and glass ionomer cements are used directly inside ‎the oral cavity to restore the function of teeth. Some of them are aesthetic. Indirect ‎restorative materials, such as porcelain fused to metal (PFM), high content gold alloys, non-precious ‎metal alloys, and indirect resin composites are prepared in a dental laboratory. But are the current dental materials already optimal and can they serve well and long enough? What different type of dental materials do we have in clinical use today? What is so special in the materials one is using in dentistry? To which direction are dental materials going? Do we have adhesive dentistry also in the future? How about 3D printing and dentistry? These are some of the questions this talk is addressing. The chemical and physical properties of restorative materials are also covered in a concise but clinically exciting and comprehensive way. Basic concepts of e.g., adhesion and bonding of dental restorative materials are also introduced.

Abstract:

Now we are at the time that personal appearance is important in our life style, teeth whitening or bleaching is the most popular esthetic dental treatment that enhances the appearance. People frequently ask dental professionals questions
about dental bleaching and its efficacy and biological safety. The lecture will answer many questions that every general dental practitioner wants to know to answer patients and to have optimum results. The presentation will cover types and natures of teeth stains, the importance of case evaluation and selection before starting dental bleaching. It will cover briefly types and materials of dental bleaching, then short discussion for the indications and contraindications of dental bleaching. Some important tips during bleaching will be covered and finally focuses on safety factors.

Doctorate Research Fellow program at the UTHSCSA, Texas in the United States. She is currently working as a Senior Lecturer and Consultant Prosthodontist/ Restoratives at University of Science, Malaysia. She has published more than 30 papers in reputed journals. She has frequently invited as a speaker in workshop or conferences locally and internationally.

Abstract:

Interactive lecture (IL) is still new things terminologically to School of Dental Sciences (PPSG), University of Science, Malaysia. Unnoticeably many lecturers has practiced it during teaching and learning activities even they are seems unaware and lack of knowledge about IL. The claims of heavy workload and less time especially by clinician might hinder the use of IL in
teaching and learning. A study has been done to find out the acceptance level for IL by dental lecturers at current time and after some exposure through intervention for the future and further planning and application at the school. Two sets of the same self-administered questionnaires were used in the study where the questionnaires consist of 4 sections (A, B, C and D) that will
take about 15-20 minutes to complete. 71% has responded for pre-intervention where 37/52 (71.15%) are clinicians and 15/52 (28.85%) is basic sciences lecturers; whereas only 51.4% responded for post-intervention. Generally, lecturers at PPSG accept the application of IL, agree about the important and show interest in applying it in their teaching. No significant difference of all acceptances to IL components tested in this study between clinician and basic sciences lecturers. Clinical lecturers gave more reasons/problems for not applying it mostly claims due to lack of knowledge, time limitation, unsatisfactory supports and facilities especially internet at the university and not suits the clinical teaching condition. Concern and strategies need to
be found to improve this problem.

Yassir Elkhidir

Suiwah Stomatological Hospital, China

Title: Ultraviolet Photofunctionalization for Speed Osseointegration
Speaker
Biography:

Yassir Abdelrahman Hag Elkhidir has completed his MDS in Oral Surgery and Implantology in 2014 from Huazhong University of Science and Technology, China. His work on titanium surface modification has resulted in remarkable improvements in the speed and extent of bone regeneration. Currently he is working in the Department of Oral Implantology and Dentofacial Surgery at the First Affiliated Stomatological Hospital of Jinan University in China.

Abstract:

Osseointegration is a prerequisite of successful implant stability and is by far the most important factor to consider before establishing any further treatment. Biological ageing of titanium is the time-related degradation of the physiochemical properties of the implant surface. Ultraviolet photo-functionalization (PhF) reverses the ageing process, increases the BIC
to almost 100% in what is known as super-osseointegration and therefore increases the strength and the primary stability of implants while decreasing the average healing time. PhF regenerates the lost hydrophilicity caused by biological ageing of titanium and converts titanium surfaces from hydrophobic to super-hydrophilic. It also optimizes the electrostatic status of the surface reverting it from electronegative back to the electropositive status found on fresh titanium surfaces. PhF also removes the significant amount of hydrocarbon that unavoidably accumulates on the surface by time leaving more space for cellular attachment. At molecular level it was shown that PhF of titanium surfaces increases protein absorption enhances osteogenic migration and attachment, as well as osteoblastic proliferation and differentiation. Clinically, PhF allows for more treatment options as shorter and thinner implants can be utilized more frequently without any compromise to the treatment outcome. PhF therefore improves prognosis, decreases morbidity and has a significant impact on clinical practice.

Title: Antibacterial efficacy of neem, triphala, green tea and combination of neem with triphala extract against Enterococcus faecalis: An in vitro study
Speaker
Biography:

Abstract:

Aim: The main objective of root canal treatment is to disinfect the entire root canal system and irrigation is an important step in reducing the bacterial load from the root canal system. However, irrigants currently used in the field of endodontic have their share of limitations, the search for an ideal root canal irrigants continues. The use of herbal extracts as endodontic irritants is today gaining popularity. This study is to evaluate and compare the antimicrobial potential of herbal extracts such as neem (Azadirachta indica), triphala (Terminalia chebula), green tea (Camellia sinensis) and combination of neem and triphala as endodontic irrigants against Enterococcus faecalis.
Materials & Methods: Freshly prepared extracts of neem, triphala, green tea and 2% chlorhexidine were used to assess the antimicrobial efficiency against Enterococcus faecalis using the agar well diffusion test. Agar plates were incubated at 37 oC for 24 hours in an incubator. The diameter of bacterial inhibition zones around each well was recorded to the nearest size in mm. Results: Higher mean zone of inhibition was recorded in chlorhexidine followed by neem extract combination of neem and triphala than triphala and green tea extract, respectively. The lowest mean zone of inhibition was found in green tea extract.
Conclusion: From the present study, it can be concluded that neem leaf extract shows comparable zones of inhibition with that
of chlorhexidine and combination of neem and triphala.

Sanjeev Kunhappan

Government Dental College, India

Title: Taming the “LEO” (Lesion of Endodontic Origin)
Speaker
Biography:

Sanjeev Kunhappan is a Conservative Dentistry and Endodontics and has completed his BDS from College of Dentistry, Indore during 1996-97. Then he worked in College of Dental Sciences as a Lecturer for 6 years. He was then selected by Public Service Commission for the post of Lecturer in Government Dental College, Raipur, India in 2005. He has completed his MDS in 2012 and has published more than 10 papers in reputed journals. His interest is mainly towards non-surgical endodontic

Abstract:

A periapical lesion is formed within an area of existing apical periodontitis, the foci of infection being the degenerating pulpal tissues within the root canal system. This pulpal degeneration is caused by the microbes that enter the pulp chamber from oral cavity. These periapical lesion regresses as soon as the microbial etiology present within the root canal is removed by nonsurgical root canal therapy. Mere surgical removal of the periapical lesion, without proper root canal disinfection and three dimensional obturations are not sufficient for its complete healing. Non-surgical endodontic treatment using triple antibiotic
paste (TAP) as intra-canal medicament to disinfect the root canal system followed by mineral trioxide aggregate (MTA) for three dimensional obturations offers a high success rate in the healing of large periapical lesions. These clinical cases highlight the healing of large periapical lesions with conservative non-surgical endodontic treatment, followed-up over a period of 2-3 years.
