DVDs + program notes 

Unlike bone, which is constantly undergoing resorption followed by bone apposition, teeth are not subject to remodeling. They are remarkably resistant to physiologic remodeling processes. The reason for this is found in the periodontium and cementum. The mechanisms that take effect in this area and the effectiveness of the periodontal system — consisting of gingiva, alveolar bone, periodontium, and cementum — after injury can be visualized in this scientific 3D film. The visualization of these complex processes is of great interest for academic teaching as well as for the clinician, as the cellular interactions are presented in this context of four phases. For the first time, scanning electron microscope images of real cells can be visualized alongside computer-animated simulations, allowing the comparison of their characteristics.

Dental Research Seminar

Published by under Dentistry
Tags:

Date: August 17, 2015 (Monday)
Time: 12:45 p.m. to 1:30 p.m.
Venue: Lecture Theatre II, G/F, The Prince Philip Dental Hospital

Presenter: Mr. Liu Quan, PhD Candidate

Title: Studies on bone-derived biological apatite: structural and compositional investigations, assessments and simulations

Abstract: Biological apatite (BAp) is the primary inorganic component of biological calcified tissues such as bones and teeth. Due to the similarity in structure and chemical composition, xenogenic bone graft materials composed of BAp have been widely used in orthopaedics, oral and maxillofacial surgery, and implant dentistry. However, a comprehensive understanding of BAp’s physicochemical properties (such as morphology, composition and solubility) has not yet been obtained because of the variety of its sources and the effects of extraction methods, as well as the drawbacks and limitations of examination methods. Therefore, the aim of this work was to investigate the structure and chemical composition of vertebrate bone-derived BAp, to assess the influence of thermal treatment on its physicochemical properties, and also to examine the effect of heating temperature and magnesium on its solubility by using synthetic hydroxyapatite (HAp) and carbonated HAp (CHAp) as simulation models.

Bone-derived BAp from several vertebrates was extracted by both low-power plasma ashing and thermal treatment. It was found that each consisted of platelet-like CHAp crystals with low crystallinity, which became rod-like or irregular particles, of larger size and higher crystallinity but lower carbonate (CO32−) content, on high-temperature treatment.

The solubility of HAp (as a model for BAp) in potassium chloride-deuterium oxide (KCl-D2O), a potential medium for the investigation of HAp’s solubility behaviour, was close to that in potassium chloride-protium oxide (KCl-H2O), indicating that there was no significant effect of D2O on the equilibration of HAp with its solution. In contrast, the effect of magnesium on HAp’s solubility was concentration-dependent; while with CHAp, another simulation of BAp, the effect of heating temperature was found to be temperature-dependent with respect to its physicochemical properties.

It is concluded that platelet-like BAp is the common inorganic component of vertebrate bones. BAp’s in vivo structure and composition as well as solubility are vulnerable to alteration during extraction involving thermal treatment. Magnesium has evident influence on BAp’s solubility although the mechanism is as yet unknown. D2O, which appears not to affect the solubility behaviour of HAp, may provide a means of preparing deuterated material suitable for detailed crystallographic analysis.

Fractured instrument removal : a systematic approach : multimedia compendium / Michael Arnold.

D 617.6262 A75  (Includes 1 DVD)

Instrument breakage is a possible complication of mechanical preparation and widening of complex root canal systems. The more difficult the endodontic treatment, the greater the risk of instrument fracture. Recent studies show that more than 90% of all broken endodontic instruments can be successfully removed without surgical intervention. However, before undertaking a removal attempt, clinicians must know how to determine when a broken instrument should be removed and when it should be left in place; the appropriate methods for broken instrument removal; and which instruments should be used for each level of difficulty. This DVD provides a simple, step-by-step strategy to instrument removal that is illustrated by numerous images and clinical case demonstrations. This systematic approach can help significantly improve the odds of successfully removing broken endodontic instruments from the root canal. The accompanying booklet includes insightful articles on minimally invasive fragment removal using CBCT as well as systematic approach to orthograde removal of fractured instruments.

Title: A randomized clinical trial on arresting dentin caries in preschool children by topical fluorides
Abstract: This study was conducted on 371 preschool children with dental caries in primary teeth. At baseline, they were randomly allocated into: Group 1 – annual application of 30% silver diammine fluoride (SDF) solution; Group 2 – three applications of 30% SDF solution at weekly interval; and Group 3 – three applications of 5% sodium fluoride (NaF) varnish at weekly interval. Follow-up examinations every 6 months were conducted to assess whether the treated caries lesions had become arrested. After 24 months, 316 children (85%) remained. For cavitated carious lesions (ICDAS code 5/6), application of SDF solution, either 3 weekly applications at baseline or annual application, arrested active dentin caries faster than 3 weekly applications of NaF varnish at baseline. However, for established carious lesions (ICDAS code 3/4), the three fluoride application protocols were equally efficient in controlling established carious lesions.

Presenter: Ms. Suen Rita Po Chu, MPhil Candidate (1:15 p.m. to 1:45 p.m.)
Title: Dental situation of institutional residents with intellectual disability in Hong Kong
Abstract: Objectives: The aim of this study is to investigate the oral health of intellectually disabled adults living in institutions in Hong Kong. We will also find out their oral health-related behaviours, and difficulties they encounter when accessing dental services.
Methods: The subjects of this study are the intellectually disabled adults who are currently living in government-subvented institutions in Hong Kong. About 750 subjects will be selected from 16 institutions through systematic sampling from the 96 institutions operated by non-governmental organisations, that contributes at least 400 subjects as the final sample size (C.I. = 95%). After obtaining informed consent, care-givers will complete a questionnaire about the dental care behaviours and problems of their cared subjects on their behalf. Additionally, dental information will also be extracted from the patient record of the outreach dental service.

Title: Flavor perception in human brain

Abstract: Flavor perception might be a system far more complicated than we can imagine. For example, we may experience a loss of taste sensation when we block our nose. Indeed, flavor perception is a multisensory integration which may involve taste, smell, tactile, visual and auditory senses. Among different combinations of sensation, the most common one is a combination of taste and smell, which will be mainly focused in this study, stimulated inside or through an oral cavity. The aim of the study is to investigate the human brain response to the interaction between a sour taste and a fruity smell. This presentation will introduce the basic concept of perceiving flavor in neuroscience and some results from the pilot study of functional Magnetic Resonance Imaging.
