Abstract:

Injectable soft tissue filler procedures are becoming increasingly important for rejuvenating the aging face. Hyaluronic acid (HA) is one of the substances used as natural dermal fillers that appear in the body naturally, but disappears with aging. Such fillers are physiological (non-carcinogenic and non-teratogenic). They are in fact temporary, but safer to use. Among the wide range of techniques for correction of aesthetic nasal defects, one of them has been gaining emphasis, non-surgical rhinoplasty with dermal filler of HA. The dermal filler of HA presents a promising alternative due to its ease of application, intimacy with tissue, efficacy and safety to the body of the patient. The gold standard surgical technique for nasal defects is traumatic, postoperative painful procedure, and which is away from the patient’s usual activities. The aim of this study was to show a clinic case of success using HA in the treatment of aesthetic nasal defects. Treatment area should be cleaned with 70% alcohol and aseptic conditions maintained during the injection. Local anesthesia may be offered for increased treatment comfort. It was done by Restylane, Restylane Lidocaine, Restylane Perlane (Sweden) for the majority of nasal treatments. Nasal reshaping was done with 1 mL Restylane Perlane, injected intradermally into the
nasal tip (0.15 ml), 0.20 ml in the nasal septum, in the anterior nasal spine supraperiostally (0.20 ml) and intradermally and supraperiostally in the dorsum (0.25 ml) with a sharp 29-G needle. The procedure was conclused with the injection of HA in the nasolabial fold upper lips (another syringe of Restylane was done-1 ml). Important anatomical considerations include the superficial vascular network and the potential risk of intravascular injections. Serious complications such as blindness and facial skin necrosis, have been reported after HA injection in the nasal and periorbital region.

Abstract:

Objective: EverStick glass fibre posts have been advocated for a new method of a direct post and core fabrication. The EverStick posts have adhesive surface and are flexible before curing therefore can be shaped individually. The purpose of this article is to describe a new technique of direct composite resin crown fabrication on a custom made EverStick root canal post.
 
Methods: At first a rubber dam isolation was achieved and the EverStick post was fabricated following manufacturer’s instructions (Figure1 A, B, C, D, E). The crown fabrication started from the palatal layer of composite resin (Gaenial JE, GC) which was applied by means of a silicon index and light cured for 20 seconds (G-Light, GC).A dual cure self-adhesive resin cement (G-CEM Link Ace A2, GC) was used to cement the post and light cured for 40 seconds Figure(2A). Two further layers of Gaenial in AO2, A2 shades were placed to obtain the dentin shape and shade of the crown (Figure2B).
For the enamel layer of the restoration Gaenial BW shade was used (Figure2C). Each layer was light cured separately for 20 seconds. The restoration was polished with diamonds (NTI-KAHLA GmbH, Germany) under water cooling. The final gloss was achieved by means of Soft-Lex discs (3M ESPE, USA) and a polishing paste (Gradia diapolisher, GC).
 
Results: The results achieved after 3 days (Figure 2D) and 12 months (Figure 2E) showed satisfactory aesthetics and marginal integrity of the restoration.
 
Conclusion: Direct composite resin crown fabrication on a custom formed root canal post could be used as an economical and conservative treatment option.

Biography:

Hollie Hawrot graduated from The University of Sheffield dental school in 2016. She was born and lives in the United Kingdom. She is a member of the Royal College of Surgeons of Edinburgh after completing the MFDS in 2018. Hollie has completed her foundation training post, dental core training in Oral and Maxillofacial Surgery and most recently worked for Floating Doctors as a lead dental provider, which is a non-profit organisation based in Panama.

Kevin Lan graduated from Bristol University in 2011 and is of Mauritian and Chinese heritage. He is a Member of the Joint Dental Faculties and regularly attends post graduate courses, specifically focused on minimal invasive dentistry. He has worked with Floating Doctors since founding the dental program in 2015 and is on the board of directors. His interests include paediatric care and developing clinics in underserved remote locations.

Abstract:

The Ngobe-Bugle populations, who are indigenous to Panama, are the largest of the three indigenous groups. Historically, they had limited contact with dental professionals and therefore, have received minimal oral health education and treatment. Floating doctors is a non-profit organization, which has a dental program that aims to improve the oral health of this population. Floating doctor’s dental health program has been running for four years and focuses on oral health education, prevention and holistic dentistry to improve the quality of life of the Ngobe-Bugle people. As the Ngobe-Bugle population is divided into multiple communities in different locations, floating doctors travels remotely by boat to 26 different locations on a three monthly basis. Mobile dental equipment is taken to the communities and extractions, restorations, stainless steel crowns and preventative treatment is provided. Furthermore, oral health education and the provision of personal oral hygiene products are fundamental in the services we provide. Since starting the dental program, floating doctors has seen an improvement in the oral health of both children and adults due to improved access and regular reviews. However, over recent years refined sugar and sugar-containing products have become much more easily accessible to these populations and presents a significant problem, much like many parts of the western world. The aim of floating doctors is to continue with the services we currently provide, but most importantly to reiterate oral health education and preventative advice so that the positive effects of this dental program can be experienced by generations to come.

Session Introduction

Aylin Pasaoglu Bozkurt

Beykent University, Turkey

Title: Effects of mechanical vibration force on tooth movement: Finite element analysis

Time : 11:35-12:00

Speaker
Biography:

Aylin Pasaoglu Bozkurt is an Associate Professor at Beykent University, Department of Orthodontics, Istanbul. She has obtained her PhD at Ege University, Faculty of Dentistry, Department of Orthodontics. Her research interests are different treatment methods used in orthodontics. She is an author of several articles in international journals.

 

Abstract:

Objective: The aim of this finite element study was to assess the effect of mechanical vibration force on tooth movement, stress distribution and velocity.
 
Methods: A 3D model was created using CBCT image of a patient with class 2 malocclusion. Three different analyses were performed on a single model where upper first premolars were extracted. At canine distalization stage; 150gf, 150 gf and 30 Hz (0.2 N), 150 gf and 111 Hz (0.06 N) were applied to canine. The first moment effect of force and vibration were evaluated using the Algor Fempro finite element analysis program. Stress and displacement
distribution were investigated comparatively.
 
Results: It was observed that the maximum displacement occurred in the second analysis (150 gf-30 Hz), while lower displacement was seen in the third analysis (150 gf-111 Hz), and the lowest amount of displacement was in the first analysis (150 gf). While only force application caused extrusion of the tooth, linear and vibration forces together caused intrusion. In the first analysis canine rotated in the distovestibule direction, but in the second and third analysis, canine showed distopalatal rotation.
 
Conclusion: It was concluded that in a certain range, mechanical vibration force may have accelerated tooth movement.

Abstract:

The current dental environment has suffered through many dietary changes through the years; from a more abrasive low-sugar diet to a softer, more acidic and more sugary evolved diet. This has been evidenced through the increase in dental diseases, such as caries and erosion, leading to a surge of the need for fillings and extractions. This is particularly prevalent in pediatric patients. New dietary changes have been introduced into society, such as vegetarianism and veganism. These in turn have had an impact on the dentition, such as reduced calcium intake from dairy products in veganism and a less abrasive diet in vegetarianism through the exclusion of chewing meat. Another major factor in today’s society is stress. This has a huge impact through wear and myofascial pain caused by bruxism, irregular eating patterns that could lead to dental diseases, smoking which compromise periodontal health and the increase in eating disorders, such as bulimia, which increase the risk of dental erosion. It is the aim of this presentation to evaluate the anatomical changes of the jaw, dentition and oral cavity and the progression of oral diseases through the years as diet and society have progressed.

Biography:

Abdul Rahman Khan has his expertise in orthodontics and he is a Clinician and a Researcher. He wants to improve his skills and wants to bring new ideas oftreatment and improvement in the treatment provided.

Abstract:

Introduction: About 1/3rd of orthodontic patients have class II malocclusion and different treatment options are available for the treatment. It is the goal of orthodontics to give an ideal smile to the patients and therefore this study
was conducted to compare the outcomes of different treatment protocols.
 
Materials & Methods: A cross-sectional study was conducted using pretreatment and post-treatment photographs, cast and post-treatment radiographs of 135 subjects being divided into 3 treatment protocols: Upper premolar extraction (UPE), clark’s twin block (CTB) and class II elastics (C2E) treatment modality. The cases were analyzed using ABO-OGS, IOTN and PAR index. Wilcoxon-Signed Rank test was used to compare the pretreatment and post-treatment malocclusion scores. Mann-Whitney U test and Kruskal-Wallis test were used to compare the scores among treatment modalities. p≤0.05 was kept as a level of significance.
 
Results: The ABO index indicated that more failure with C2E followed by CTB and UPE (40, 33.3 and 20%) respectively. PAR and IOTN showed statistically significant improvement.
 
Conclusion: All treatment modalities are effective however; C2E has more failure cases as compared to other modalities.

Karl Lee Kingsley,

University of Nevada, USA

Title: MicroRNA expression in dental pulp stem cells

Time : 14:00-14:25

Speaker
Biography:

Karl Lee Kingsley teaches Microbiology and Immunology, Biostatistics and Epidemiology and research methods in the Department of Biomedical Sciences at UNLV School of Dental Medicine (DMD) program. His research focuses on oral cancer and oral biology, including dental pulp stem cells.

 

Abstract:

Introduction: Dental pulp stem cells (DPSCs) are non-embryonic, mesenchymal stem cells that may have significant potential for therapeutic and regenerative biomedical applications. MicroRNAs are small non-coding RNA molecules that can act as transcriptional activators and repressors in many types of mesenchymal stem cells. To date, few studies have evaluated the expression or activity of microRNAs among dental pulp stem cells.
 
Methods: Using eight previously isolated and characterized DPSC lines, RNA was extracted and examined using PCR to determine expression of several key miRNAs, including miR-16, miR-27, miR-124, miR-135, miR-143 and miR 218.
 
Results: These data demonstrated that at least four of these microRNAs are active among some of these DPSC isolates, including miR-16, miR-27, miR-124 and miR-218.
 
Discussion: Although the transcriptional targets of these miRNAs are not yet known, it is evident that the differential expression of some of these miRNAs (miR-27, miR-124, miR-218) may correlate (or even contribute) to differentiation status of these isolates. More research will be needed to determine the precise function and targets of these microRNAs to determine their effects on DPSC differentiation, which may foster biotechnology applications for DPSC bioengineering applications.

Hala Aoun

Lebanese University School of Dentistry, Lebanon

Title: Evaluation of hearing in children treated with palatal expansion

Time : 14:25-14:50

Speaker
Biography:

Hala Aoun is an orthodontist that studied dentistry and graduated in 2005 as a dental surgeon from the Lebanese University, school of dentistry. Then studied for three full time program at American university of beirut and at the Lebanese University and graduated in 2010 with a diploma in orthodontics and dentofacial orthopedics. For the past nine years, Dr Hala Aoun has been running her own private dental clinic where she is practicing all types of orthodontic treatments using fixed and removable appliances and clear aligned as well. She aims to proceed with her research idea and to run new studies and gain more acknowledgments.

 

Abstract:

The aim of this presentation is to explore the potential association between rapid palatal expansion RPE and decrease in conductive hearing loss. RPE is a common orthopedic treatment for maxillary constriction and or lateral crossbite. This procedure may result in unexpected improvement of nasal breathing and improvement in nasal sensitivity. The underlying mechanism for the latter would consist of the extension of the tensor veli Palatine muscle
following the palatal distraction, which opens the Eustachian tube orifice and facilitates air passage, allowing normal function of the middle ear system. Clear cut conclusions are not yet formulated on whether the improvement in
hearing is transient or permanent. A thorough review of the literature with methodological shortcomings and design of future studies are reported.

Abstract:

Statement of the Problem: Using mouthwashes have been recommended to limit dental caries, periodontal diseases
and due to their affection for restorative dental materials. The longevity and durability of the aesthetic composite
resin restorative materials are important factors in the oral environment. However, many studies conducted the
effect of some mouthwashes on the surface hardness and accuracy of composite resin.
Aim: The purpose of this study is to investigate the effect of both Listerine alcohol-contained and GUM alcohol-free
mouthwashes on the surface hardness and dimensional accuracy of light-cured composite resin.
Methodology & Theoretical Orientation: 30 disc-specimen of nanohybrid light-cured composite resin was prepared
for this study (Smile USA, shade A2). According to ISO standardization, the disc dimension was of 12(±0.2mm) in
diameter and thickness of 3(±0.2mm). The sample divided into three groups (n=10) (3-readings each), G1: Control
non-treated (distilled water); G2: Listerine (Alcohol-contained mouthwash) (Johnson and Johnson, UK) and; G3:
G.U.M (Alcohol-free mouthwash) (Ivohealth, South Africa). The specimens were measured for surface hardness
using Shore D and for dimensional accuracy by digital vernier caliper device at different immersion intervals. These
include pre-treatment (initial), after 1 week, after 4 weeks, and after re-curing. Data were analyzed via one-way
ANOVA (post-hoc Turkey test) performed at a confidence level of 95% and a significant P-value of (P≤.05).
Findings: Within the study limitation, both Listerine alcohol-contain and G.U.M alcohol-free mouthwashes had
no effect on the hardness and dimensional accuracy of the composite material before recurring. While after the
re-curing process, only GUM mouthwash showed a reduction in the surface hardness of the composite material.
Further studies were needed to estimate the effect of mouthwashes on the micro-hardness and wearability of the
composite materials.

Abstract:

Dental implant technology was first introduced nearly 42 years ago and it has a dramatic transformation in the
dentistry industry as well as an alternative to traditional treatments. Nowadays, implants are a good treatment for
patients who cannot use their complete denture and who missed their teeth and it should be noted that dental implants
besides the incredible advantages have disadvantages and at the same time correct management of the diagnosis before
and after surgery is important to prevent further problems. In this article, Author tried to investigate the treatment plan as
well as the management of complications before and after implant surgery. Common complications may include factors
such as incorrect treatment plan, sinus perforation, mandibular fracture, lack of primary stability, wrong angulation that
can be determined by the proper diagnosis of the treatment plan, having CBCT, proper surgical guide and the dentists
experiences, which can be a major factor in managing and preventing further complications.
