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.

Biography:

Kavita Ravi-Shankar has completed her Graduation at King’s College London in 2016. Following this she carried out her vocational training in the Kent, Surrey & Sussex deanery. Currently, she is pursuing her dental core training in Oral & Maxillofacial Surgery. Alongside her clinical duties, she has achieved distinction in the Postgraduate certificate in Primary Dental Care and merit in the Postgraduate Diploma in Primary Dental Care. She is pursuing her Masters. She has keen interest in the evolution of dental health and dentistry through the ages.

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.

Recently, appointed as a committee member for the IADR KULZER Travel Award and for three years starting from 2019 (International & American Associations for Dental Research, Alexandria, Virginia-USA).

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.

Title: Diagnosis and management of complications of implant surgery
Biography:

Omid Panahi has completed his Graduation at Centro Escolar University as Doctor of Dental Mediciene and has completed his MSc in Oral and Maxillofacial
Surgery at Yeditepe University, Istanbul, Turkey. He has published more than 40 papers in reputed journals and has been serving as an Editorial Board Member
of ISI journals.

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.

Biography:

Hollie Hawrot is a Lead dental provider in Floating Doctors which aims to promote Oral and dental health care delivery worldwide.

 

Abstract:

Statement of the Problem: The Ngobe-Bugle populations, who are indigenous to Panama, are the largest of the three indigenous groups. Historically, they have had limited contact with dental professionals and therefore, have received minimal oral health education. Over recent years, refined sugar and sugar-containing products have become much more easily accessible to these populations. There is very limited research on the oral health of the Ngobe-Bugle populations and therefore the DMFT (decayed, missing and filled teeth) of the paediatric population is unknown.

Aim: The purpose of this study is to calculate a DMFT rate for the paediatric patient’s in the Ngobe-Bugle population, and compare it to the DMFT rate of children in Panama as a whole.

Methodology & Theoretical Orientation: Using standard WHO methodology, examinations for missing teeth and caries were completed by three dental professionals who calculated a DMFT rate. Data was collected retrospectively and patients from the age of 5-18 were included in the study. Unerupted teeth, congenitally missing teeth, supernumerary teeth and third molars were not included in the study. An average DMFT score was calculated for 12 year-olds and as an average for 5-18 year olds, and was compared to the DMFT rate of 12 year olds in Panama.

Findings: The DMFT rate of 12 year-olds in the Ngobe Bugle population was higher than the DMFT rate of 12 year-olds in Panama.

In 2012 she has joined the National Laboratory for Research in Applied Molecular Biology and Immunology at the University of Tlemcen, under the direction of Professor Mourad ARIBI In 2015. She enrolled in the Doctoral program in medical sciences where, she learned about the therapeutic effects of metallo proteinases responsible for carious disease in children. After completing additional training, she obtained a Diploma of Sub-specialization in Clinical Health Research at the University of Oran, and in June 2018, a certificate in E-learning in specialized endodontics.

Abstract:

Introduction: Diabetes mellitus is one of the most common chronic diseases in children. However, several studies have shown that unbalanced diabetes is often associated with changes in the oral environment namely altered buffering capacity, xerostomia, high numbers of Streptococci and Lactobacilli which increases the risk of dental caries.

Aim: To reduce the appearance of Streptococcus sanguinis involved in dental caries.

Materials & Methods: After recruiting diabetic children, two young patients responding to informed consent, underwent salivary sampling for isolation and identification of the bacterium, microbial activity of the extracted oil was evaluated by the disc diffusion method, then a minimal inhibitory concentration was sought, then antioxidant activity was achieved by the free radical trapping method DPPH    

Results: Carious disease is present in 80% of diabetic children, 72% had unbalanced diabetes with an average HbA1C level of 8.1+/-1.6%. The disc diffusion method has shown that essential oil of cumin has intermediate activity on Streptococci sanguinis. The inhibition diameter is 14mm. This oil also has a more interesting antioxidant activity (CI50=0.02) than ascorbic acid (CI50=0.048) All experiments were performed in triplicate. Data were analyzed using SPSS software 21.0 (Chicago, IL, USA). The data are expressed as the mean±standard deviation values. The statistical analysis was done using Student's t-test. Values of p<0.05 were considered statistically significant.

Conclusion: Given the high prevalence of carious disease in diabetic children. The essential oil of cumin revealed an interesting intermediate activity on S. sanguinis, to prevent the installation of the lesion.

Title: Child’s oral health-A hand in hand approach
Speaker
Biography:

Abstract:

Dental care is the most unmet care need of children which places more than 52% of children at risk of untreated oral disease. Those at increased risk include poor or minority families or children with special health care needs. Children and RSQUO`S oral health care can be predicted from their development changes and their position in life span and the deficiency, in the context of environment and current demographic changes. It is always said that “Prevention is better than cure”. So we should try to prevent oral diseases in a child rather than curing it at later stages as it will be more time taking and costly. Now a days special gap in education include training of general dentist to care for infants and young children as well as pediatric providers and other professionals caring for child in oral health promotion and disease prevention. Education should focus on technical aspects of interdisciplinary approach as child and RSQUO`S oral health care can be improved by integration of dentistry with medicine and other health care professionals. Child`s oral health should be a hand in hand approach. Oral health is shared moral responsibility of dental and other medical professionals working with children, parents and society.

Biography:

Jinesh Shailesh Thakrar has completed his Graduation at Birmingham Dental School in 2015 and is currently working as a Dental Officer at Hertfordshire Community NHS Trust. He has also spent time working in Oral and Maxillofacial Surgery as a Senior House Officer. During his time at University he noticed a number of patients having their wisdom teeth and a secondary molar removed due to caries and was interested to investigate further.

Abstract:

Third molar surgery is one of the most common procedures performed in oral surgery. There is no controversy when it comes to removing third molars which show signs of pathology or present with symptoms but prophylactic removal of third molars has caused lots of debates for a number of years. Before the National Institute for Clinical Excellence (NICE) created the guidelines for third molar extractions, wisdom teeth extraction was a very common procedure costing the NHS around £30 million per year and roughly £20 million was spent privately. From 27th March 2000 NICE published guidelines on wisdom teeth removal resulting in a decrease in 30% of wisdom teeth extractions. It does not however include distal decay in the second molar as a reason for removal. My research project looked at wisdom teeth referrals into Birmingham Dental Hospital, UK and assessed which NICE guidance category they fell under as well as if there was any radiographic evidence of distal decay in the second molar. A total of 69 cases were assessed, 45 female and 22 male. The most common age group of referrals was between 24 and 30 with 61% of all cases presenting with a vertical impaction. Caries was the most common reason for referral (39%) with 22% of all cases having radiographic evidence of caries in the lower second molars. Of those that presented with caries in the lower second molars only 33% had it mentioned in their referral letter and this was most commonly in mesially impacted lower wisdom teeth. There is relatively low proportion of those with evidence of caries in the second molar and so I would not consider it to be a necessary change for NICE guidelines. I would however put more emphasis providing oral hygiene advice to patients with mesially impacted wisdom teeth.
