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.

Title: Improving Oral Health for Children with Autism Spectrum Disorders

Abstract: Autism Spectrum Disorders (ASD) is a spectrum of developmental disorders characterized by impairments in communication and social skills. Maintaining good oral health requiring special care is a challenge because of multiple learning, communication and cogitative impairments. This has been the focus of my thesis with a theme of research relating to special care dentistry.

A systematic review of the oral health status of individuals with autism spectrum disorders was undertaken across five electronic databases employing PRISMA guidelines. The initial search yielded 727 papers, among which 36 were identified as potentially effective papers and 11 ‘effective’ case-control studies informed this review. Variations in oral health existed among children with and without ASD in terms of dental caries experience, periodontal health, malocclusion, dental injuries and bruxism. This has implication for special care practice and policies.

To understand ASD and oral health in the Hong Kong context a population-wide oral epidemiological study was undertaken among 17 randomly selected registered Special Child Care Centres. An age (±6 months) and gender matched sample of children from mainstreams preschools were recruited as the ‘control group’. Comprehensive oral health assessments were undertaken for over 500 children. Difference in clinical oral health status existed among preschool children with and without ASD in terms of dental caries experience (dmft>0), periodontal health (pp<0.001).

A clinical trial was undertaken to evaluate the effectiveness of a tooth-brushing visual pedagogy to improve oral health and enhance oral self-care among children with ASD in both intervention and control groups. Improvements in oral hygiene status and gingival health were observed over the 6-month period. Regression analyses identified the visual pedagogy intention was a significant factor associated with improved oral health (p This has implications for safeguarding and promoting good oral health among children with ASD in Hong Kong and beyond.

An introduction to oral and maxillofacial surgery / David A. Mitchell and Anastasios N. Kanatas.

D 617.67 M67

 

The surgical specialty of oral and maxillofacial surgery is sometimes less recognised in the UK. This is due to its complex training requirements necessitating dual degrees in medicine and dentistry and formal general and specialist surgical training and qualification. This volume is a definitive yet concise source of reliable information for UK trainees following the ISCP curriculum. Following a similar structure, approach and delivery as the original, the content matches the updated Intercollegiate Surgical Curriculum Project (ISCP) curriculum for oral and maxillofacial surgery.

Oral and cranial implants: recent research developments / Hugh Devlin, Ichiro Nishimura, editors.

D 617.674 O63 D49

 

Dentists are routinely faced with a huge choice of implant systems from different manufacturers, each of whom claims that its own particular system has advantages over the others. There is consequently a need for an evidence-based review of the field that offers authoritative practical guidance for dental practitioners. Oral and Cranial Implants: Recent Research Developments has been written with this in mind. It brings together all the recent key developments in implant research and discusses the underlying science relating to implant procedures and failures. Relevant literature is reviewed and clear practical advice is offered. This book will be ideal for dentists wishing to obtain a snapshot of research in the field and will also be useful for specialists in restorative dentistry. The authors are recognized leading authorities who are well equipped to evaluate the applications and challenges associated with implants.
