Title: A lab-centered approach for initiating early regeneration of dental pulp using specialized alginate biomimetic microenvironments.

Abstract: There is a significant need in modern endodontics to have living replacement for dental pulp that can salvage the infected necrotic tooth. The first step towards fabricating a dental pulp tissue is to construct a suitable cellular structural microenvironment. In this study we establish an environment by judicious selection of hDPSC and HUVEC encapsulated in RGD alginate infused with physiologically relevant quantities of VEGF and FGF. These environment constructs were fabricated in template of gutta percha shape mold. They were analyzed for viability, proliferation, morphological changes, distribution and growth factor release kinetics. Results from confocal and SEM showed uniform distribution of cells along the length of construct. They were viable with significant rate of proliferation, morphological changes and cell-clustering phenomena noted with formulation in constructs having one or both added growth factors than in growth factor-free constructs. The release kinetics showed significant results in groups with dual growth factors. We conclude that combining VEGF and FGF in 1:3 ratio to co-culture of DPSC-HUVEC could initiate denovo regeneration.

Presenter: Dr. Zakir Muhammad, PhD Candidate (1:15 p.m. to 1:45 p.m.)

Title: Bonding dissimilar materials in dentistry

Abstract: Bonding of dental restorative materials to tooth tissues is one of the most important aspects in dentistry. To meet the harsh oral environment coupling agents are used to enhance the adhesion between different materials. There has been considerable research on silane coupling agents compared to other coupling agents. Adhesion of metals and resin cements is the most important aspect for the longevity of the prosthesis. Titanium is used as a material of choice for dental implants and other metal dental prosthesis. Our aim is to use an optimized novel silane system and compare and contrast its adhesive properties to the commercially available surface modifiers and resin cements when titanium and resin cements are bonded. Different mechanical tests such as shear bond adhesion test, fractural analysis, scanning electron microscopy, atomic force microscopy (for surface roughness), energy dispersive X-ray spectroscopy are some tests which are going to be conducted. All the tests are going to be done after the specimens have been aged in water and after thermocycling. All the obtained data will be statistically analyzed and presented in the thesis and published studies.

“Original Sin”? Revising the Revisionist Critique of the 1963 Operation Coldstore in Singapore

Kumar Ramakrishna

“Revisionist” or “alternative” historians have increasingly questioned elements of the Singapore Story — the master narrative of the nation’s political and socioeconomic development since its founding by the British in 1819.

Institutional Engineering and Political Accountability in Indonesia, Thailand and the Philippines

Patrick Ziegenhain

Political accountability is a crucial element of any democracy since it is a safeguard against power abuse and corruption, both urgent problems of many political systems in Southeast Asia. Based on social science theories, the author analyses from a comparative perspective the ways institutional engineering concerning different dimensions.

The Armed Forces in Myanmar Politics: A Terminating Role?

Robert H Taylor

While Myanmar’s constitution under which the current government of President Thein Sein was created in 2011 has all the characteristics expected of a modern republic, the continued autonomy and political role of the armed forces are perceived by opponents of the regime as an anomaly.

China’s Quest for Energy in Southeast Asia: Impact and Implications

Zhao Hong

Energy cooperation between China and ASEAN countries since its initiation in the late 1970s has been viewed as an important part of China-ASEAN relations. As China expanded its FDI to Southeast Asia after the global financial crisis in 2008, cooperation in this field developed to a new level, extending from energy trade to energy resource exploration and related infrastructure-building.

Templer and the Road to Malayan Independence: The Man and His Time

Leon Comber

Dr Comber’s account of General Templer’s administration in Malaya as High Commissioner and Director of Operations (1952–54) during the Malayan Emergency departs from the usually accepted orthodox assessment of his time in Malaya by focusing on the political and socioeconomic aspects of his governance rather than the military.

Mirror Images in Different Frames? Johor, the Riau Islands, and Competition for Investment from Singapore

Francis E Hutchinson

In the early 1990s, Singapore, the Malaysian state of Johor, and the Riau Islands in Indonesia sought to leverage their proximity, differing factor endowments, and good logistics connections to market themselves as an integrated unit.

Title: Oral Health Promotion Intervention Among Stroke-Carers and Patients

Abstract: Disability caused by stroke can decrease patients’ quality of life through impacts on daily life activities. Rehabilitation services for patients with stroke are dedicated to improve the condition of patients and to support independence through education and training.  Oro-motor function and clearance are commonly perturbed following stroke, and daily toothbrushing is also impaired due to reduced manual dexterity.  Dental plaque accumulates at a faster rate, and opportunistic bacteria and yeast proliferate. While maintenance of oral health is a great challenge for patients after stroke, health care staff and caregivers are ideally positioned to support and assist these patients to maintain oral hygiene so as to prevent not only oral diseases but also life-threatening infections such as aspiration pneumonia.  Evaluations of oral care provided by caregivers and approaches for optimizing such care have received little attention.  Thus, this study aims to evaluate the factors that determine the oral health behavior of stroke care providers, and the impact of a tailored Computer-Assisted-Learning (CAL) programme.

Title: Bioimimetic Nature-Derived Antibacterial Surfaces for Modified Denture and Dental Restorative Materials

Abstract: Control of the oral microbiome under different disease, inflammatory and degenerative challenges is possible with antibiotics, anti-quorum sensing molecules and toxic heavy metals such as, silver nanoparticles. However, bacteria can quite rapidly evolve resistance to chemical agents. They cannot evolve mutations to counter physical structures that are able to damage and destroy them. Therefore, attention has focused on the use of micro- and nanostructures to kill pathogenic bacteria particularly derived from nature where self-cleaning surfaces are common.
In dentistry the ultimate aim is to develop strategies that affect species that have become virulently pathogenic and restore a normal interdependent balanced microbiome. Previously it has been reported that Cicada wing surfaces can selectively remove pathogenic, gram negative while maintaining non-pathogenic species. The post-like protrusions are effective in rupturing the membrane of thin-walled bacteria represented by the gram negative staining classification. We have studied a range of potential nature-derived candidates as templates for antibacterial surface structure. Gecko skin fulfils criteria for a superior antibacterial surface structure, because it consists of high aspect ratio nanohairs, confined in tight spacing and eliciting superhydrophobicity. Such intricate structures can be copied in any material allowing for their exploitation in biomedicine and dentistry.
The aim of this study is to measure the short-term bactericidal properties of gecko skin, and Epoxy resin polymer imprints and assess their feasibility to control two ubiquitous species of “surface associating” pathogenic oral bacteria with virulent biofilm forming potential. The goal is to confirm whether these surface structures can be usefully applied as bactericidal coatings at the surface of dental implants and restorations requiring bacterial control management.

Title: Possibility of Key-Hole Revision of Endodontic Treatment

Abstract: The nonsurgical revision endodontic treatment may involve the perforation of intact crown, decementation of crown or crown and bridges and disobturation of radiographically satisfactory obturation, which may be unacceptable to the patient many a times. The option of surgical approach may not appeal to the patient or it may be too invasive in terms of the size of the persistent lesion or new lesion formed or just symptomatic tooth as described by the patient all of which have known to be of microbiological origin.
This research evaluates the possibility of an approach to a surgical technique, which is based on the concept of keyhole surgery in conjunction with photodynamic dye and laser activation to eradicate the extra-radicular infection in endodontically treated tooth and the periapical region. The feasibility is assessed in a series of experiments to evaluate the parameters that make this procedure a clinical possibility
