Abstract:

PDO threads is a synthetic absorbable surgical suture composed of polydioxanone (PDO). It’s a hypodermic needles preloaded with an absorbable PDO suture. Thread lifting is a procedure that works to tackle sags and folds. The procedure is becoming more popular than ever before as demand grows for skin care where less is more.The PDO thread lift is designed to help restore your facial structure and reduce the visible signs of ageing without the need for surgery. The PDO lift works by using threads-cannula (thin tube) beneath the skin and attaching them to the surrounding tissue to lift the face and tighten the skin. The PDO thread lift works by redefining the facial contours and inducing collagen production creating a lifting effect which lasts for up to 2 years. The threads will form an integrated support structure for the tissue of the face due to collagen synthesis. Usually, ten to thirty threads are applied in a treatment, requiring a local anaesthetic, that can last from 30 minutes to 1 hour. Expect mild to moderate swelling, but recovery time is on average two to three days. The threads, which come in different lengths, are pulled up to create the lift and can be successfully combined with filler and other treatments.

The results can be noticed immediately, but it is necessary to reduce the edema to view the effects under the skin.

Session Introduction

Jeffery Lynn Hicks

University of Texas Health San Antonio, USA

Title: Dental clearance prior to medical intervention in patients with liver failure

Time : 11:10-11:35

Speaker
Biography:

Jeffery Lynn Hicks served as a Chair of the Department of Hospital Dentistry in San Antonio, Texas, USA for 11 years and he has developed expertise in the care of patients with complex medical problems. In particular, he has developed algorithms for the oral health care treatment of patients with organ failure and cancer. He currently directs training projects and writes for US federal training grants for the University of Texas Health San Antonio School Of Dentistry.

 

Abstract:

As many as one in 10 Americans have some form of liver disease. Cirrhosis and chronic liver failure are leading causes of morbidity and mortality, with most cases due to excessive alcohol intake, viral hepatitis, or nonalcoholic fatty liver disease. Routine liver function tests do not correlate well with degree of liver function but with liver cell damage instead. Liver transplant is the only effective long-term treatment for chronic liver failure. The study detailed in this paper was undertaken to determine: 1. the oral disease presence in patients with liver failure awaiting liver transplant; 2. the oral health care determined to be necessary to clear patients for transplant and the costs of that oral care; 3. the effectiveness of an examination and treatment algorithm in the evaluation and care of liver failure patients; and 4. whether correlations existed among various commonly performed laboratory tests in these patients. The study showed that patients awaiting liver transplant commonly have generalized severe periodontal disease and periapical abscesses which would preclude the patient from undergoing transplant surgery. The average cost of care to issue dental clearance for the patients in this study was $1,169. Liver failure patients being considered for liver transplant surgery can be treated safely using a treatment algorithm to guide care that incorporates a few precautions to avoid post-operative bleeding. Precautions include platelet transfusion and use of agents and surgical technique to ensure hemostasis. Results of commonly used laboratory tests for liver failure patients were not found to show correlations with one another and were not considered good predictors of the risk for complications following invasive procedures.

Kumar Jashbhai Patel

Marietta Dental Care & Georgia Prosthodontics Associates, USA

Title: Evidence based approach to oral rehabilitation with contemporary Dental Materials

Time : 11:35-12:00

Speaker
Biography:

Kumar Jashbhai Patel is practicing prosthodontics in Atlanta, USA. He limits his practice to rehabilitation of debilitated dentition and post trauma and cancer reconstruction. He serves as a reviewer for Journal of Prosthodontics and served as an Editor for Georgia Dental Association. He is a fellow of American College of Dentists, International College of Dentists and Pierre Fauchard Academy.

 

Abstract:

Evidence based approach to the patient treatment is now considered a norm. Dental profession has made a strategic shift in establishing protocols, education and training based on evidence-based support. Presentation includes importance of diagnosis and treatment planning for different clinical scenarios. Contemporary rehabilitation requires planning with end results at the forefront based on evidenced based protocol. Treatment prognosis depends on optimal diagnosis, execution, material choice and technology utilized. Research can be controversial; application depends on multiple factors. Biologic, anatomic and material factors and its interplay over time dictate prognosis and longevity. Traditional and contemporary dental materials as they are applied to rehabilitation have variable success rates. Many protocols have limited and evolving supporting evidence. Patient expectations and economics of rehabilitation are important part of overall picture. Increasing longevity of human life and projected increase in population over 65 years old ads to the increasing challenge in terms of longevity of treatment protocols and simplicity of maintenance and quality of life. Treatment options in terms of evidence available in contemporary literature; application of dental materials are discussed. Limitations of different modalities and factors contributing to failures are identified. Author brings in discussion about level of evidence and strength of it in order to justify the application. Available research and evidence are scrutinized and interpreted in practical terms. Special focus of the presentation is to illustrate practical solutions for patients at different life stages with different economic and physical limitations. Presentation also discusses concept of shortened dental arch along with quantitative and quality functional needs. Use of fixed vs. implant retained and implant supported prosthesis, clinical protocols and maintenance protocols are discussed. Basic esthetics concepts and its application to overall treatment planning within biologic system are discussed.

Biography:

Cesar Dos Reis Perez is an Associate Professor of State University of Rio de Janeiro (UERJ). He is working in Dental Materials and Prosthesis Graduation and Post-Graduation. He has his expertise in Non-Carious Cervical Lesions and Development of Dental Materials.     

 

Abstract:

Statement of the Problem: Considering some factors as the growth of the elderly population, the smaller rate of tooth loss, and possibly the increase of some etiologic factors as inadequate brushing techniques, corrosive food and drink consumption, and occlusal stress concentrating factors (occlusal interferences, premature contacts, habits of bruxism, and clenching), the treatment of non-carious cervical lesions can be considered a matter of great importance. Unfortunately, Class V restorations also represent one of the less durable types of restorations and have a high index of loss of retention, marginal excess, and secondary caries. Some causes for these problems include difficulties in isolation, insertion, contouring, and finishing and polishing procedures.

Objective: This presentation aims to help dentists in choosing the best treatment strategy, which necessarily involves steps of problem identification, diagnosis, etiological factor removal or treatment, and, if necessary, restoration. Finally, appropriate restorative techniques are suggested for each situation.

Biography:

Mahitab Hassan Elgash, passionate and driven general practitioner Dentist in Alrehab Medical Center, UAE. He studied in National Ribat University, Sudan. He has a heart and goal to keep bright smile on every patient. Communicate kindheartedly to ease all the pressure and trauma on every patient.

 

Abstract:

Statement of the problem: Dental hygiene manner, smoking, and recognized dental health setbacks among individuals.

Background: Dental manners play a major role in terms of preventing oral diseases. To go further, only few people are aware of the relationship of smoking with the potential of oral diseases. More specifically, it appears that smoking interferes with the normal function of gum tissue cells. This interference makes smokers more susceptible to infections, such as periodontal disease, and also seems to impair blood flow to the gums - which may affect wound healing. However, this issue has not been previously tackled with importance.

Aims: Putting that into consideration, this study aims to analyze the behavior towards oral hygiene, habitual smoking and foreseen dental health problems among residents of UAE.

Material & Methods: An observation and interview with regards to dental hygiene practices, smoking and a perceived oral health problem was performed. Smoking results more serious problem regarding health that the patients are not fully aware. The method was descriptive study, predominantly focused to regular dental patients (smokers and non-smokers) visiting the clinic in the regular basis. The subject were asked how they usually clean their teeth and what the other methods they use, for example are if they frequently use mouthwash and routinely floss their teeth and how often they perform the said behavior. They were also asked about the potential problems they might encounter in the long run.

Results & Conclusion: It is found out that the dental hygiene methods demonstrated by the patients (UAE residents) were alike. It is necessary to increase the awareness of dental professionals about negative effects of smoking on oral and general health. Furthermore, they should be more aware of their central role of healthcare workers as promoters of healthy lifestyle among patients. Most of the participants brushed and cleaned their teeth, however, only once per day. An attitude towards smoking was manifested clearly by the majority. Those who smoke regularly foreseen problems in oral health compared to those who do not. Healthcare provider (dentist) should encourage giving more proper care on their patient regarding about the risk of smoking on their health, with the proper knowledge about smoking, and manner of thinking from simple step will lead to a better improvement of their health.

Title: Root canal morphology and its implications in Endodontic therapy

Time : 14:10-14:35

Speaker
Biography:

Adil Hamed Alani is an endodontist with close to 41 years’ experience in the field. He has completed his BDS from the Dental School, University of Baghdad in 1978. He got his higher Dental Diploma in 1981 at the same School in conservative Dentistry and furthermore was awarded a PhD Degree in Endodontics from the Dental School, University of Dundee, Scotland, UK. He has published many articles in both local and International Dental Journals, and was invited as an External Examiner in various Dental Schools. He has also presented in a considerable number of lectures in both local and international conferences.

 

Abstract:

The hard tissue repository of the human dental pulp takes on numerous configurations and shapes; the variations of anatomical and morphological characteristics of the teeth are very important for any practitioner. These differences in root morphology determine the success of the endodontic therapy and the long-term prognosis of the tooth, especially when it is an abutment for a prosthetic restoration. Before beginning an endodontic treatment, the clinician must take into account the morphological variations of the root anatomy. A thorough knowledge of tooth morphology, careful interpretation of angled radiographs, proper access preparation and a detailed exploration of the interior of the tooth are essential prerequisites for a successful treatment outcome; magnification and illumination are aids that must be utilized to achieve this goal. This presentation describes: How the lack of knowledge in root and pulp anatomy permits errors in diagnosing and treatment planning; A thorough understanding of the complexity of the root canal system is essential for understanding the principles and problems of shaping and cleaning, for determining the apical limits and dimensions of canal preparations; Unfilled canals, left like this by omission, can compromise both the endodontic and prosthetic treatment; Describes and illustrates tooth morphology and discusses its relationship to endodontic procedures.

His area of research interest includes cancer and oral pathology.

 

Abstract:

Oral squamous cell carcinomas (SCC) of the mandible present the lowest survival rates of the whole oral cavity. Oral region metastases are considered uncommon. The most frequent sources of metastatic tumors to the mouth are primary cancers from the lung and breast with the latter being the most common site for tumors that metastasize to the jawbones. Treatment involves surgery, radiation, chemotherapy or in combination. However, these treatment modalities involve severe aesthetic and functional side effects. The aim of this lecture is to present an alternative and unprecedented treatment modality for metastatic mandibular bone carcinoma-cryosurgery. A 37-year-old female patient who presented with gradually increasing pain over several weeks whose radiological tests revealed the formation of mass in the left mandibular ramus. Histopathologically, metastatic breast squamous cell carcinoma was reported. The patient has been effectively treated without aesthetic and functional side effects by using for the first time worldwide cryosurgery. We conclude that it is valued promoting this method for current and future use.

He 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:

Nowadays, a large number of people can be found with missing teeth who don’t know the consequences of empty space between their teeth. This lack of awareness leads to the destruction of other teeth, increased therapeutic costs and longer treatment duration. A dental implant is a new therapeutic approach that can be used for replacing the missing teeth. Prior to implant technology, dental bridge was used as the best treatment plan, and infact the traditional and old form of treatment has become a new method for replacing missing teeth. In this clinical research, I have tried to investigate the advantages and disadvantages of both methods. Choosing a correct and accurate treatment plan for the patients can be a success factor in the treatment. Both treatment plans are used as alternative for the missing teeth and can vary according to some of the parameters including the patient-specific treatment plan, financial aspect, the appearance of teeth and the comfort care.

Abstract:

Cosmetic dentistry is considered as one of the priorities for people need all around the world in a high percentage. Most of the patients nowadays are looking for cosmetic corrections. The reason behind this patient demand may have a great effect on the psychological behavior of the patient. The variation of this demand depends on the severity of the appearing beauty of the smile line of the patient. According to this aspect, some of these patients may become shy, and others may become aggressive with psychological trauma. Also, some of these patients may isolate themselves from the community in a way that may not share any social activities and the end result is inferior complexity. Far from this, another type of patients they may look for cosmetic correction just for new fashion. In other words, they do not have serious cosmetic problems. Accordingly, the clinician here is playing the role of a dentist and a psychiatrist at the same time. This is where the role of the dentist as a psychiatrist emerges to restore confidence to the spirit of that patient and when we win the trust of the patient, this is the biggest support for dental marketing. Winning the trust of the patient is the largest aid to the marketing of dental services, taking into account that you deal with the utmost honesty and loyalty with your patient. Hence, the dentist may change the social life of the patient. In other words, you are rehabilitating the life of your patient. The difficulties in cosmetic correction may vary from one case to another depending on many factors. This article discusses these difficulties by displaying some clinical cases report of patients suffering from problems in the smile line. Most of these patients had psychological trauma, and they were looking for an immediate solution. Meanwhile, they were looking for a dentist with a deep emotion that has a spiritual behavior towards them. The conclusion of this article indicates how you can solve the problem of your patient's smile, which may negatively affect his/her social life. This means you did not take the role of the dentist only, but the role of the psychiatrist which means this role will be the biggest incentive for this patient to pay you what you see appropriate and this is the most important part in dental marketing.

He is the Researcher and head of the Laboratory of Oral Biology, Institute of Dental Medicine, First Faculty of Medicine and GUH, Charles University, Prague.

 

Abstract:

Aim of the study: The purpose of the study was to compare presence of periopathogenic bacteria in sites intended for implantation therapy in dentistry with success of this therapy.

Material and methods: Fifty-four patients underwent implantation therapy by titanium implants from BTLock company (Italy). Before dental implantation therapy started, saliva samples from implantation site were collected. From these samples, microbial DNA was isolated by DNeasy Blood & Tissue Kit (QIAGEN). Presence of periopathogenic bacteria Tannerella forsythensis, Porphyromonas gingivalis, Prevotella intermedia, Prevotella nigrescens, Aggregatibacter actinomycetemcomitans and Capnocytophaga ochracea was determined by qualitative PCR using periopathogenic bacteria specific primers.

Results: Prevotella nigrescens was found in 64.3 % of patients, Prevotella intermedia was found in 28.6 % of patients, Tannerella forsythensis was found in 25 % of patients, Porphyromonas gingivalis was found in 14.3 % of patients, Capnocytophaga ochracea was found in 12.5 % of patients and Aggregatibacter actinomycetemcomitans was found in 1.8 % of patients. Implantation therapy was successful in all patients.

Conclusion: Presence of periopathogenic bacteria in implantation sites was common in patients undergoing implantation therapy. Despite this fact, there was no problem with implant healing and implantation therapy was successful in all patients.

Biography:

Radka Vrbova has completed her studies at the University of Chemistry and Technology. She has been working at the Institute of Dental Medicine, where she focuses on testing the physico-mechanical properties of dental materials. She completed her Postgraduate Studies at the Czech Technical University with the specialization in Biomechanics. Her area of interest includes development and research of new implant materials.  

 

Abstract:

Statement of the problem: The disinfection of dental impressions is currently a necessary step before further processing in dental laboratories. However, the disinfection of impression materials can lead to the deterioration of their surface properties with negative impact on the quality of the resulting prosthetic work.

 

Objectives: The purpose of this study is to compare the effect of several commercially available disinfectants on the accuracy of various types of dental impression materials and their compatibility with gypsum including surface quality and structure evaluation.

 

Material & Methods: In this study alginate (Alligat fast set, Elastic Cromo, Kromopan, Phase Plus) and elastomeric (Variotime Medium Flow, Xantropen L blue, Impregum Soft) dental impression materials in combination with four disinfectants (Aseptoprint Liquid, Zeta 7 solution, Silosept, Dentaclean Form) and gypsum type 3 (Mramorit Blue) and type 4 (BegoStone plus) were tested. The dimensional changes were measured and the detail reproduction, compatibility with gypsum including observation of surface quality and surface structure were evaluated using three imaging methods - light microscopy, scanning electron microscopy (SEM) and micro computed tomography (micro-CT). The results were statistically analyzed using Statistica 12 software (StatSoft Inc.).

 

Findings: Dimensional changes after disinfection were higher in alginate materials (even over 1%) for some combination of impression material /disinfectant. All imaging methods proved that the detail reproduction, surface quality and compatibility with gypsum of the tested alginate impression materials were most negatively influenced by disinfectant Dentaclean Form. The surface quality of tested elastomeric impression materials remained unchanged after disinfection. It was confirmed that the desired properties of impressions may be negatively affected by disinfectants, particularly in the case of alginate materials, and that the effect of disinfectants is very individual.

Eman Maged Fouad Ahmed is an active researcher, holds master degree from Ain Shams University and high deploma degree from NILES in medical applications of laser, working as dental specialist at Air force specialized hospital, Egypt and as clinical instructor at Future University in Egypt and currently DM student at ElAzhar University. She expresses high enthusiasm regarding health improvement, especially in field of laser advancements and biological aspect of endodontics.

 

Abstract:

Background: Over years, the main goal of endodontic therapy has focused on the total elimination or at least major reduction of root canal microorganisms, which has never been guaranteed yet. Recently photoactivated disinfection (PAD) through activation by laser irradiation has been suggested as a promising supplement to root canal disinfection. It is further enhanced by incorporation of concept of nanotechnology.

Aim: Aim of the study was to evaluate the antibacterial effect of PAD protocol with or without silver nanoparticles against E. faecalis biofilm.

Materials & Methods: 60 single rooted teeth were decoronated and the root canals were mechanically prepared. Then roots were inoculated with E. faecalis isolate and incubated at 37°C for 7 days. They were divided equally into three experimental groups and one positive control group. The first group canals were irrigated with 2.6%NaOCL for 5 minutes. Second group subjected to PAD protocol where canals were filled with 100µg/ml methylene blue (MB) and irradiated with 660 nm, diode laser at power of 250 mW for 180 seconds. Third group canals were inoculated with both NgNPs and MB and irradiated at same settings.

Results: They were assessed quantitively through counting the colony forming units

(CFU/ml) while scanning electron micrography was performed to address topographical changes of experimental groups. All of experimental groups resulted in significant high reduction in bacterial population, however the synergistic effect of NgNPS was very obvious and the colony counts reached 0. Micrographs confirmed the presence of the dense heterogeneous smear layer in G1, modification of smear layer with partial opening of dentinal tubules in G2 while demonstrated total absence of smear layer and clear surface of dentine in G3.

Conclusion: Incorporation of NaNPs with PAD protocol represents a very promising modality in regard to root canal disinfection.

Abstract:

Background: It has been observed that there is an increase in Candida carriers during the treatment with orthodontic removable appliance. Vanillin is a flavouring agent, which is known to have antioxidant and antimicrobial properties.

Objectives: The purpose of this study was to investigate the effect of vanillin incorporated PMMA on adhesion of Candida albicans.

Material & Methods: A total of 54 orthodontic self-curing PMMA resin samples were fabricated. The samples were divided into 3 groups depending on percentage of vanillin incorporated (0.1%, 0.5% and 0% as control). PMMA samples were coated with saliva. The adhesion assay was performed with C. albicans (ATCC 10231) and a clinical strain isolated from oral lesion of a patient. The adherent yeast cells were stained with crystal violet and counted under microscope by random selection of 3 fields at 10X magnification. The statistical significance was analysed by Kruskal-Wallis and Mann-Whitney non-parametric test.

Results: It was found that the PMMA resin samples with vanillin incorporation significantly reduced the adhesion of C. albicans as compared to the control group.

Conclusions: This study indicates that vanillin incorporated resin can impede the adhesion of C. albicans (ATCC 10231) about 45-56% and clinical strain about 55 to 60%. With further testing and development, vanillin can be employed as an antifungal agent to prevent adhesion of C. albicans to orthodontic self-curing PMMA resin.

Abstract:

Background & Aim: We aimed to evaluate the knowledge and attitudes of Iranian dentists towards cone-beam computed tomography (CBCT).

Materials & Methods: A 20-item questionnaire was distributed among 410 Iranian dentistry graduates attending the 56th Congress of Iranian Dental Association held in Tehran, Iran. The questionnaire included items on demographic characteristics, namely full name, age, gender, work experience, type of current activity (individual or group), and the highest educational level. In addition, the questionnaire contained items on knowledge and attitudes of dentists. The obtained data were analyzed by using statistical tests.

Results: In this study, 49.3% and 22.4% of the subjects were male and female, respectively, 47.1% of whom used CBCT, while 49.8% did not. In detail, 72.2% of the dentists used the technique to evaluate the location of implant, whereas 19.7%, 3.2%, and 2.7% of the subjects applied it to localize the inferior dental canal, evaluate the location of implant and localize the canal, and perform cephalometric analysis. The main causes of lack of prescription of CBCT entailed high cost (80%), high rate of patient absorbed dose (27.6%), insufficient number of CBCT centers (46.3%), and long duration of the process (15.6%).

Conclusions: CBCT is an advantageous imaging technique in dentistry. With regards to the increased application of CBCT in all domains of dentistry, holding workshops in the form of exclusive courses or in congresses could help train dentists to use the technique.

Abstract:

Osseo-integrated implants have become a routine solution for treating edentulous patients. Dental implants have a favorable long-term prognosis when compared to conventional fixed prosthodontics. The implant length is usually considered during the treatment planning and the length is decided based upon the existing bone. After teeth extraction the jaw bone volume is lost creating a real challenge to place implants with adequate length. Moreover and subsequent to poor bone volume; implant placement become risky as we have some important anatomical structures such as the nasal cavity, maxillary sinus mental nerve, mandibular nerve and lingual vascular bundle. There are many surgical procedures to compensate for bone deficiency, such as sinus and/or ridge augmentation procedures. They are proven to be successful in providing sufficient bone quantity and quality for implant placement and prosthetic support; however, increased cost, surgical time, morbidity, and healing time are often associated with these procedures. Hence implants with alternative length and diameter were introduced in response to clinical demands. In the last decade, use of short implants has become a growing interest among clinicians. Encouraging survival rates have been reported over time. Recent systematic reviews indicated that short implants have the same survival rates and degree of marginal bone loss as longer implants. Short implants bio-compatibly transfers occlusal forces from abutment to surrounding bone. The entire design of short implant optimizes the effectiveness of each of the features within the available implants surface area and length. Short dental implants could be a reliable and predictable alternative solution for those cases with less than optimal ridge bone volume. This lecture focuses of both clinical and biological aspects of short implants in our routine clinical practice.
