Abstract:

A biocompatible, low elastic modulus Ti-7.5Mo alloy with an alpha-double-prime (α”) orthorhombic crystal structure for medical applications has been developed at National Cheng-Kung University (NCKU). The mechanical properties of this alloy can be adjusted via different processes for different applications. Its ultimate tensile strength/modulus ratio through one specific process can be more than 200% of Ti-6Al-4V ELI, 300% of grade-4 cp-Ti, and 500% of grade-2 cp-Ti, while its elongation can be adjusted to 10-40%, depending on the application. The low modulus feature is expected to reduce the stress-shielding effect often observed in rigid metallic and ceramic implantation studies. This Ti-7.5Mo alloy is expected suitable for making a dental crown & bridge, RPD, dental implant, orthopedic fixation, miniplate, etc. A head-to-head comparison between α” Ti-7.5Mo and the popularly-used grade-2 cp-Ti in dental casting-related performance shows that cast Ti-7.5Mo alloy performs consistently superior to the cp-Ti. In addition to its much better castability (by 25-100%, depending on wax paten design) and machinability, the unique combination of higher strength and lower elastic modulus of Ti-7.5Mo alloy offers a far higher elastic recovery angle which has advantages over cp-Ti for certain applications such as RPD clasps. The interesting cold working-induced α’’-α’ phase transition phenomenon is also discussed in this presentation. The research was funded by the Ministry of Science and Technology (MOST) Grant No. 107-2221-E-006-016.

Abstract:

Abstract:

Nowadays, aesthetic is no more an option in our treatments, especially in young patient who is at a critical time of his social integration. This challenge have to be manage by a minimally invasive way, guided by a therapeutic gradient. We need to lavish treatment aesthetic, functional, biomimetic and the atraumatic for the tissues as possible. This paradigm shift is induced by the fact this young patients have to growth, live and evolve with our treatments in a long term period of life. This clinical case shows a minimally invasive way to restore the aesthetic and function of a multiple dental agenesis in the anterior zone of the maxilla in a young patient.

Abstract:

The human immune system plays a vital role in the defence against foreign as well as few self antigens like tumour antigens. Chemotaxis is essential for the release of inflammatory mediators capable of producing an immune reaction at the site of infection or targeting tumour cells. Allopathic immunomodulatory drugs, although potent, comes with its fair share of disadvantages like hepatotoxicity, intestinal and oral mucositis. We evaluated the the immuno-modulatory activity of herbal concoctions in boosting the chemotactic activity,
intracellular killing property and anti-tumour activity. Neutrophils and lymphocytes were isolated from peripheral blood using magnetic bead seperation. Immunomodulatory effect of Triphala on the Chemotactic activity of leukocytes was evaluated using modified Boydens transmigration chamber.
Intracellular killing activity of Neutrophils was evaluated spectrophotometrically using Nitroblue Tetrazolium (NBT) reduction method. Antitumour activity of the Triphala enhanced lymphocytes was evaluated using MTT assay on Human Oral squamous cell carcinoma cell lines. The results of the study revealed Triphala enhanced the chemotactic, intracellular killing and antitumour activity of Leukocytes in a dose-dependent manner. The results indicate that herbal concoctions can be used as an alternative to chemotherapeutic immuno-modulation in case of immunodeficiency as well as
in cancer immunotherapy and precision medicine.

Abstract:

Oral mucositis is one of the serious side effects of chemotherapy and radiotherapy. Complications secondary to oral mucositis include ulcers, pain, dysphagia, dysgeusia, infection, eating and breathing problems, as well as mucositis on the gum and dental condition of patients. Mucositis can affect the patient’s self-confidence and reduces the quality of life of by reducing the ability to communicate. The purpose of this study was to evaluate the diet of a person under cancer treatment on the severity of chemotherapy and radiation therapy induced mucositis. Twenty-one cancer patients who referred to Imam Khomeini Hospital in the middle of the cancer treatment phase and completed the first stage of chemotherapy and were waiting for their next stage of treatment, were randomly selected. At this stage, the patients were examined by
a dental and oral dentist and the severity of mucositis was determined by a dentist according to the World Health Organization (WHO) criteria. Completion of diary for 3 days, Allergen nutrient inventory and nutritional recommendations were completed at this stage. After completion of the forms, 4 questionnaires were completed for each patient and the diet of patients was analyzed in N4 software and the amount of macro and micronutrients were
determined. Afterwards, the relation of dietary intake with the severity of oral mucositis (Grade 1 to 4) was investigated. For analyze of regression model SPSS software was used. (P <0.05) In this study, among all the studied micro and macronutrients: the micronutrients of the amino acids aspartic acid, glycine, proline, alanine, arginine, glutamic acid and vitamin b12, and macronutrients including rose water, coffee and veal, there was a significant difference between group 1 (grade 1 mucositis) and group 2 (grade 2 mucositis). It can be concluded from this cross-sectional study that diet is effective on the severity of mucositis caused by cancer treatments.

Biography:

Marwa Baraka is working in Tanta University, Egypt

Abstract:

Introduction: Various forms of malocclusion are usually encountered in non syndromic cleft lip and palate, mostly affecting maxillary dental arch.

 

Objective: To assess the dental arch parameters in surgically treated unilateral cleft lip and palate Egyptian children with mixed dentition and compare them with those of comparable healthy non-cleft children.

 

Material and methods: Comparative cross-sectional study design was used. Twentysix non-syndromic children with repaired unilateral cleft lip and palate (UCLP), aged 6-9 years, were compared to twentysix healthy non-cleft children (control group) recruited from Faculty of Dentistry, Alexandria University. Both groups were divided into two age groups; 6-7 years and 8-9 years. For each subject, dental arch parameters were measured using dental study models.

 

Results: Mean maxillary arch depth and inter-canine arch width were significantly smaller in UCLP children than in non-cleft children in the age groups 6-7 and 8-9 years. Mean inter-molar arch width was not significantly narrower in UCLP children than in non-cleft children. Mean mandibular arch dimensions of UCLP children did not differ significantly from those of non-cleft children. The mean Goslon Yardstick score was 3. Conclusions: Children with UCLP, aged 6-9 year old, had significant reduction in mean maxillary arch dimensions compared to healthy matching non-cleft children except for inter molar arch width which showed no significant reduction. The average dental arch relationship in surgicallyrepaired UCLP children was fair according to Goslon Yardstick index.

Biography:

ARGHAVAN TONKABONI is working at the Department of Oral & Maxillofacial Medicine, School of Dentistry, Tehran University of Medical Sciences, Tehran, Iran. She has completed his DDS degree at the age of 25 years from Tehrasn University of Medical Sciences and also has continued M.S. studies in the fiel of ORAL & MAXILLOFACIAL MEDICINE, from Mashahd University of Medical Sciences 2011. She was head of department ORAL & MAXILLOFACIAL MEDICINE DEPARTMENT, School of Dentistry, 2012-2017. She has published more than 20 papers in reputed journals and has been serving as an editorial board member of repute.

Abstract:

Oral lichen planus (OLP) is a chronic autoimmune cell-mediated disease affecting mucocotaneous tissues of oral cavity. Recent studies revealed that psychological stress may act as a trigger to initiate clinical symptoms. An
8-year-old girl complaining of oral ulcer, pain and irritation in mouth with onset of 3 months ago, was admitted to oral medicine department. Her medical history was negative except for severe psychological trauma in last 6 months. Intraoral examination showed bluish purple atrophic erosive striations with hyperkeratosis. Pathological study of buccal lesions confirmed OLP diagnosis. As all primary investigations were negative; psychogenic origin was suspected. Although it is rare for a child to have OLP but it should be taken into consideration in differential diagnosis of red and white oral lesions in children. Huge impact of psychological factors in the occurrence of oral diseases have suggested that they should be treated in combination with psychotherapy.

Title: Innovative inclinations in forensic odontology
Biography:

Kamla Naveeda is the principal dental surgeon at a private dental clinic. She has been one of the main proponents of this program for several years, and it a true stand out in this field. She has a great understanding of the program and a great appreciation of what it takes to truly make and continue on a path of progress, and a remarkable vision of the future of dentistry. She has participated in many articles in regard to forensic Dentistry. Also, she has been a part of many dental conferences at her hometown. She has been awarded several certificates of participation and also rewarded as the most fascinating speaker.

Abstract:

Forensic odontology is an evolving science with a superior scope of development. It has proven as an indispensable science in medico-legal matters and in the identification of the dead person. The dental tissues are preserved even if the deceased person is skeletonized, decomposed, burnt, or dismembered. Various methods have been developed to determine age, sex, and ethnicity of the person, using dental tissues. Data collection methods
and supplementary technologies used in forensic dental identification have undergone significant transformation. This article provides an overview of the evolving trends in conventional methods, and the recent concepts used in forensic odontology. Forensic dental identification plays a primary role
in the identification of remains when postmortem changes, traumatic tissue injury, or lack of fingerprint record invalidate the use of visual or fingerprint
method. In courts, dental evidence has been used for the past many years. The techniques used in forensic odontology has evolved through the evolution of
humankind. Forensic odontology has three major areas of use as follows: (1) diagnostic and therapeutic examination and evaluation of injuries to jaws,
teeth, and oral soft tissues (2) the identification of individuals, especially casualties in criminal investigations and/or mass disasters (3) identification,
examination, and evaluation of bite marks that occur with some frequency in sexual assaults, child abuse cases, and in personal defense situations. Dental tissues are often used to determine the age, sex, and ethnicity of a person who can either be a victim or a suspect.

Title: Effects of Er:YAG, Nd:YAG, and 940 nm diode laser irradiation on the microtensile bond strength of self-etch adhesive
Biography:

LOGHMAN REZAEISOUFI is Associate Professor who is working as a Faculty member at the Department of Restorative Dentistry, Dental Research Center, Dental Faculty, Hamadan University of Medical Sciences, Hamadan, Iran He has completed his DDS degree at the age of 25 years from Tehran University of Medical Sciences and also has continued Specilized Restorative (operative) Dentistry felowship in Mashahd University and Laser felloship course at the Achen University. He has published more than 30 papers in reputed journals and has been serving as an editorial board member of repute.

Abstract:

Nowadays, studies show that laser irradiation can enhance the adhesion of
bonding agents to the dentin. Therefore, the present study was set to find an appropriate protocol for the use of Nd:YAG, Er:YAG, and 940 nm diode lasers
during the application of the 6th generation of adhesives for dental restorations. A total number of 100 healthy extracted teeth were distributed in the ten groups. Control group(C) was prepared according to the manufacturer’s guideline. Each of the remaining 9 groups were treated with Er:YAG, Nd:YAG
and 940 nm diode lasers in following stages: Before applying primer (Er BP,Nd-BP,D-BP), After applying primer (Er-AP,Nd- AP,D-AP) and after applying bonding (Er-AB,Nd-AB,D-AB. The strength of microtensile bonding was measured using the universal testing machine. The data were analyzed using one-way ANOVA followed by post hoc Tukey test (p<0.05). The results of the means and standard deviation of the groups were as follow: C=30.09±4.21,
Er-BP=18.83±4.21,
Er-AP=14.43±3.12,
Er-AB=19.67±4.96,
Nd-BP=20.35±5.55,
Nd-AP=39.85±4.13,
Nd-AB=18.16±3.36,
D-BP=26.74±5.05,
D-AP=28.11±5.12,
D-AB=37.28±5.61.
The means of two groups: Nd:AP and D-AB were significantly higher than control groups. (p<0.05) D-BP and D-AP had no siginificant difference in
comparison with control group while the remaining groups had significantly lower values (P<0.05). It was demonstrated by the present study that implementing the Nd: YAG laser system after the primer and also implementing the 940nm diode laser after the bonding significantly improved the bond strength.

Argishti Hayrapetyan

Yerevan State Medical University, Republic of Armenia

Title: Understanding the most successful incisal preparation designs of anterior teeth for porcelain laminate restorations
Biography:

Argishti Hayrapetyan completed a Bachelor of Science in 2011 and pursued to obtaining his Master of Science degree in 2013 from Yerevan State Medical University. Thereafter, the General Family Dentistry residency was completed in 2015. He is a member of the Armenian Dental Association, attended University Hospital of Olomouc, Czech Republic, Division of Dentistry and Oral Surgery for professional exchange in complex dental restorations. He is currently in the field of restorative dentistry, specializing in diagnosis and management of diseases of the teeth and their supporting structures and the
rehabilitation of the dentition to functional and aesthetic requirements of the individuals at “Drampyan Clinic” in Yerevan, Armenia.

Abstract:

Veneer restorations are one of the most conservative and aesthetic techniques
applied as treatment of unaesthetic anterior teeth as they avoid aggressive dental preparation; thus, maintaining tooth structure. The continued development of materials offers clinicians many options for creating highly aesthetic and functional laminate veneers. Correction of minor malformations of anterior teeth with minimal removal of the remaining tooth structure, correction of crown length and width, diastema closure and masking, as well as some intrinsic discoloration of anterior teeth are examples of solutions that can be gained with using porcelain veneers. Initially, laminates were placed on the
unprepared tooth surface. Although there is as yet no consensus as to whether or not teeth should be prepared for laminate veneers, currently, more  conservative preparations have been advocated. Because of their aesthetic appeal, biocompatibility, and adherence to the physiology of minimalinvasive
dentistry, porcelain laminate veneers have now become a restoration of choice.
Today, limited controversial information is available regarding the influence of preparation design on the longevity of laminate restorations. The purpose of this presentation is to attempt to review the different incisal preparation designs of porcelain laminate veneers for anterior teeth. A further objective is to understand which is the most successful design in terms of preparation.

Title: The efficacy of Vizilite®Plus and Oral CDx in the diagnosis of oral cancer: A prospective study
Biography:

Soliman Ouda is working in King Abdulaziz University, Saudi Arabia

Abstract:

Objective: To study and compare the efficacy of Vizilite®Plus and computer-assisted brush biopsy (Oral CDx), a non-invasive adjuvant diagnostic aids, in the detection and assessment of oral potentially malignant, and/or malignant lesions.
 
Study Design: This is a prospective study that included a total of 500 patients referred to Oral Medicine clinics of King Abdulaziz University Faculty of
Dentistry (KAUFD), and regional Ministry of Health (MOH) hospitals, presenting with oral mucosal lesions over a 24-month period which were referred for further management. All cases were examined with Vizilite®Plus.
Cases with positive results were subjected to Oral CDx. Positive or atypical Oral CDx lesions, as well as negative Oral CDx lesions with clinical suspicion of precancer/ malignancy, were scalpel biopsied.
 
Results: The sensitivity of Vizilite®Plus in detecting dysplasia/malignancy was
100% whereas the specificity was 30.3%. The positive predictive value was 19.29%, whereas the negative predictive value was 100%. The positive
likelihood ratio was 1.43 and the negative likelihood ratio was 0. The sensitivity of Oral CDx in detecting dysplasia/malignancy was 97.4%, whereas
the specificity was 78.94%. The positive predictive value was 52.44% whereas the negative predictive value was 99.22%. The positive likelihood ratio was 4.6
and the negative likelihood ratio was 0.03.
 
Conclusions: Because of its low positive and negative predictive values, we do not advocate Vizilite®Plus as a useful adjunctive tool for the diagnosis of oral cancer. Oral CDx is more promising and can be utilized as an aid for the early diagnosis of suspicious oral lesions with limitations.

Title: Periodontal disease and diabetes: Association and connections
Biography:

Abstract:

The term “diabetes mellitus” denotes a number of diseases marked by high levels of glucose in the blood and abnormalities of fat, carbohydrate, and protein metabolism. A group of oral diseases and disorders has been associated with diabetes mellitus, and periodontitis has been identified as a probable risk
factor for poor metabolic control in subjects with diabetes.
 
Methods: The researcher reviewed the literature to characterize oral conditions that are hit by diabetes mellitus. She also scrutinized the literature related to periodontitis as a modifier of glycemic control.
 
Results: Despite the fact that a group of oral diseases and disorders has been linked to diabetes mellitus, the data braces the fact that periodontitis is a  complication of diabetes. Patients with constant and poorly controlled diabetes are at higher risk of developing oral candidiasis, and the evidence shows that periodontitis is a risk factor for poor glycemic control and the development of other clinical complications of diabetes. Evidence suggests that periodontal changes are the first clinical demonstration of diabetes.

Title: Natural resistanceassociated macrophage protein 1 gene polymorphism is associated with chronic periodontitis not periimplantitis in an Iranian population: A crosssectional study
Biography:

Mehdi Kadkhodazadeh has completed his Doctor of Dentistry from Shahid Beheshti University of Medical Science and Periodontology from the Mashhad University of Medical Science. She is the Director of Periodontology. She has published more than 40 papers in journals.

Abstract:

In inflammatory diseases such as peri-implantitis (PI) and chronic periodontitis (CP), both adaptive and innate immunity play a part. Natural resistanceassociated macrophage protein 1(Nramp1) has considerable effects on macrophage function (phagocytosis) and host innate immune response against infections. The present study was to investigate the relationship of Nramp1 gene polymorphisms with PI and CP in an Iranian population. In this crosssectional study 79 patients with CP, 38 patients with PI and 84 healthy controls presenting to the Periodontology Department of Shahid Beheshti University of Medical Sciences were enrolled. DNA was extracted from fresh blood samples of arm vein of participants and transferred to the KBiosience Institute (United Kingdom) for genotyping. χ2 and Fisher’s exact tests were
used by SPSS software v.19 for statistical analyses. Significant differences were detected in the distribution of genotypes between control and CP groups
both for rs17235409 and rs2276631 polymorphisms (P:0.044 and P:0.028
respectively). Distribution of genotypes differed insignificantly in comparison of PI and control groups for rs2276631 (P:0.623) and either rs17235409 (P:1)
polymorphisms. Based on our results, we conclude that the presence of G allele in both rs2276631 and rs17235409 location may be a protective factor against CP. More studies with a larger sample size in different populations are required for confirming Nramp1 as a genetic determinant in periodontal disorders.

Title: Lip repositioning surgery treatment option for a gummy smile: A case report
Biography:

Abeer Ahmed has completed her M.Sc. from King Saud University in 2017. Currently, she is studying the doctorate program from King Saud University College of Dentistry. In addition, she is a researcher in King Saud University at Periodontology and Community Dentistry Department.

Abstract:

A gummy smile is an excessive display of the gingiva or imbalance in the gingival-tooth ratio. It has different etiological factors such as vertical maxillary excess, short upper lip and altered passive eruption which cause a major aesthetic concern for many patients that may be reflected in their social or behavioral daily life, thus several techniques have been developed for its treatment. Treatment varies according to the etiological factors,
perception, and expectations of the patients like orthodontics, orthognathic surgery, cosmetic surgery, and periodontal surgery (including gingivectomy,
apically repositioned flap and lip repositioning technique). Lip repositioning surgery, chosen mainly in the treatment of hypermobile upper lip and excess
gingival display, consists of the removal of a stripe of mucosa from the maxillary vestibule and suturing the lip mucosa with the mucogingival junction. It is well tolerated by patients and results are irreversible with a very high rate of satisfaction. This report will present the results of clinical cases and the demonstration of the procedure step by step. Indications, objectives, limitations and patient’s outcome will be explained.

Sung Ho Kim

Dankook University School of Dentistry, Republic of Korea

Title: Esthetic improvements through systematic diagnosis and treatment procedures in patients with unesthetic maxillary anterior proportion after orthodontic treatment: A case report
Biography:

Sung Ho Kim has completed his bachelor’s degree at the age of 25 years from Dankook University. He is currently a resident at the Department of Prosthodontics, Dankook University and studying for a master’s degree of prosthodontics. He participates in as a member of The Korean Academy of Prosthodontics (KAP) and The International Team for Implantology (ITI). His current research focuses on Ceramic Prosthesis, Digital Dental Technology, and Implant Restorative Dentistry. He is involved in basic and clinical research on Oral Implantology and Applied Digital Dental Technology.

Abstract:

The treatment of areas demanding esthetic requirements, such as maxillary anterior teeth, should take into account the achievement of a healthy, harmonious to the surrounding tissue, and an attractive smile line. In this case report, the smile line, soft tissue and hard tissue morphology, and the anatomy and proportion of the tooth must be considered. In patients with an unesthetic maxillary anterior ratio due to inadequate gingival contour and diastema caused by peg laterals in maxillary lateral incisors, it would be challenging to achieve
an esthetic restoration by orthodontic treatment alone. In such a case, after orthodontic treatment, gingivo-dentofacial compositional diagnosis and analysis, followed by gingivectomy and prosthodontic restoration are needed to improve the interdental mesial/
distal, width/length ratio to achieve a satisfactory aesthetic result. In addition, when improving the tooth proportion of peg laterals by prosthodontic treatment, Porcelain laminate veneer (PLV), which results in less tooth structure loss, reproduction of similar shade to that of the proximal tooth and high transparency, is recommended. This case report demonstrates esthetic improvements by prosthodontic restoration through systematic diagnosis and treatment procedure in patients with an unesthetic maxillary anterior
proportion after orthodontic treatment due to peg laterals in maxillary lateral incisors by
means of two female patients aged twenty years old.

Title: Dental arch parameters and Goslon Scores in mixed dentition of Egyptian children with surgically repaired unilateral cleft lip and palate
Biography:

Marwa Baraka is currently working in Tanta University, Egypt

Abstract:

Introduction: Various forms of malocclusion are usually encountered in non-syndromic cleft lip and palate, mostly affecting maxillary dental arch. Objective: To assess the dental arch parameters in surgically treated unilateral cleft lip and palate Egyptian children with mixed dentition and compare them with those of comparable healthy non-cleft children.
 
Material and methods: Comparative cross-sectional study design was used. Twentysix non-syndromic children with repaired unilateral cleft lip and palate (UCLP), aged 6-9 years, were compared to twentysix healthy non-cleft children (control group) recruited from Faculty of Dentistry, Alexandria University. Both groups were divided into two age groups; 6-7 years and 8-9 years. For each subject, dental arch parameters were measured using dental
study models.
 
Results: Mean maxillary arch depth and inter-canine arch width were significantly smaller in UCLP children than in non-cleft children in the age groups 6-7 and 8-9 years. Mean inter-molar arch width was not significantly
narrower in UCLP children than in non-cleft children. Mean mandibular arch dimensions of UCLP children did not differ significantly from those of non-cleft children. The mean Goslon Yardstick score was 3.
 
Conclusions: Children with UCLP, aged 6-9 year old, had significant reduction in mean maxillary arch
dimensions compared to healthy matching non-cleft children except for inter-molar arch width which showed no significant reduction. The average dental arch relationship in surgicallyrepaired UCLP children was fair according to Goslon Yardstick index.
