Title: ZONE-SPECIFIC GENE EXPRESSION OF MANDIBULAR CONDYLAR CARTILAGE: A Promising Approach or an Overcomplicated Strategy?

Abstract: Mandibular condylar cartilage (MCC) possesses a unique multizonal structure to perform its function as a lubricating and load-bearing surface in the TMJ and as a growth plate cartilage. Trauma and/or pathogenesis of the MCC, which has limited capacity for regeneration, are significant causes of morbidity in human beings. Thus, tissue engineering may provide an ideal solution, but current zone-specific information is limited to a small set of genes and proteins. Resolving functional and phenotypic differences between cell populations of the MCC is important to understand mechanisms of homeostasis and pathogenesis. In addition, the identification of zone specific differential gene expression is useful in tissue engineering approaches to recapitulate the native zonal architecture.

The aim of our study is to obtain new insights into the characterization of MCC cells by investigating gene expression profiles of individually isolated MCC zones. The question that arises: is this zonal-based investigation a promising approach or just an overcomplicated strategy?

Presenter: Miss Ren Chong, PhD Candidate (1:15 p.m. to 1:45 p.m.)

Title: A randomized controlled trial of a laser-aided orthodontic treatment for patients with periodontitis

Abstract: The objective of this double-blind randomized controlled trial is to assess the effects of low-level laser therapy (LLLT) in orthodontic patients with periodontitis on pain, periodontal inflammation, alveolar bone remodeling and dentin sensitivity. Thirty-five nonsmoking patients (male or female, 18-60 years old) with controlled chronic periodontitis will be recruited. After insertion of the first archwire, one side of the arch will be randomly assigned to repeated LLLT (940nm, continuous mode and energy density: 3.57 J/cm2) and the other side to placebo laser. Following parameters will be recorded on selected time-points during the 12-month follow-up: visual analogue scale, bite force, cytokines in gingival crevicular fluid, bacteria levels in supragingival plaque, clinical parameters and cone-beam computed tomography. This study will provide first-hand evidence for the incorporation of LLLT in adjunctive orthodontic treatment for patients with chronic periodontitis.

Smile! : your guide to esthetic dental treatment/ Douglas A. Terry.

D 617.627 T32 s

 

Many patients are unaware of the wide range of treatment options available for esthetic dental restoration and enhancement, and it is often difficult for them to visualize the change that is possible with such treatment. This book presents full-page images to show how various areas of the mouth can be restored and transformed to make the smile more esthetic. Before-and-after photographs of exceptional quality reveal the significant improvements that are possible with procedures as simple as crown lengthening, composite restoration, or veneers. Other topics include all-ceramic crowns, fixed partial dentures, connective tissue grafting, implant therapy, and esthetic contouring. The author also addresses tooth fracture and diastema closure, missing teeth, noncarious lesions, sealants, interproximal restoration, inlays and onlays, minor orthodontics, bleaching, and root canal therapy. Smile! Your Guide to Esthetic Dental Treatment is the perfect tool for showing patients how they can benefit from esthetic dental treatment.

Date: May 5, 2015 (Tuesday)
Time: 12:45 p.m. to 1:45 p.m.
Venue: The Lounge, 7/F, The Prince Philip Dental Hospital

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.

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.

 

Presenter: Dr. Govindool Sharaschandra Reddy, PhD Candidate (1:15 p.m. to 1:45 p.m.)
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

Ethical decision making in dentistry/ [edited by] Suzanne U. Stucki-McCormick.

D 617.6871 E8

 

Ethical principles are essential in the practice of dentistry, and Ethical Decisions in Dentistry takes the reader from ethics in dental education to creating ethical protocols and public policy. This concise volume covers ethics issues in the education of dentists, in licensure and licensing examinations, in solo and group private practice, and in esthetic dentistry. It also supplies a chapter presenting the patient’s perspective on medical ethics, one on informed consent, and another on the process of developing the guidelines for ethical dental decision-making. The topics of billing, office management, and advertising are covered, and the book closes with a chapter entitled Ethics in Transition, which charts transitions in a dentists practice and career as well as transitions in how ethical principles themselves are viewed. Ethical Decisions in Dentistry is a valuable text for teaching ethics in dental schools, but also serves as a refresher course for practicing dentists at any stage of their professional lives.
