IMPLANTS IN ESTHETIC ZONE MYTHS AND TRUTHS Prof. PhD Bratu Emanuel Victor Babes University of Medicine and Pharmacy, Timisoara, Romania The presentation will touch all aspects of implantation in the aesthetic area and possible mistakes. It will also be discussed the aspects of time tracking of the cases, significant augmentation and insertion techniques and the type of implant chosen in this area. Participants will receive clear notions prosthetic cases in the aesthetics, and how to avoid mistakes that can be fatal in these situations.

ANALYSIS OF COMPLICATIONS FOLLOWING BONE AUGMENTATION Prof. Gabi Chaushu, DMD, MSc    Rabin Medical Center, Beilinson Campus, Petah Tikva, Israel BACKGROUND: Bone grafting may be associated with soft and hard tissue complications. Recipient site complications encountered using cancellous block allografts for ridge augmentation are analyzed. METHODS: A total of 101 consecutive patients (62 females and 39 males; mean age 44 ± 17 years) were treated with implant-supported restoration of 137 severe atrophic alveolar ridges augmented with cancellous bone-block allografts. Alveolar ridge deficiency locations were classified as anterior maxilla (n = 58); posterior maxilla (n = 32 sinuses); posterior mandible (n = 32); and anterior mandible (n = 15). A total of 271 rough-surface implants were placed. Recipient site complications associated with block grafting (infection, membrane exposure, incision line opening, perforation of mucosa over the grafted bone, partial graft failure, total graft failure, and implant failure) were recorded. RESULTS: Partial and total bone-block graft failure occurred in 10 (7%) and 11 (8%) of 137 augmented sites, respectively. Implant failure rate was 12 (4.4%) of 271. Soft 16-18 October 2014

tissue complications included membrane exposure (42 [30.7%] of 137); incision line opening (41 [30%] of 137); and perforation of the mucosa over the grafted bone (19 [14%] of 137). Infection of the grafted site occurred in 18 (13%) of 137 bone blocks. Alveolar ridge deficiency location had a statistically significant effect on the outcome of recipient site complications. More complications were noted in the mandible compared to the maxilla. Age and gender had no statistically significant effect. CONCLUSIONS: Failures caused by complications were rarely noted in association with cancellous block grafting. The incidence of complications in the mandible was significantly higher. Soft tissue complications do not necessarily result in total loss of the graft.

OCCLUSAL REHABILITATION OF PATIENTS WITH MUSCULO-ARTICULAR DYSFUNCTION BY APPLYING MODERN DIGITAL TECHNOLOGIES Adj. Prof. Valeriu Fala PhD Associate Professor, Department of Therapeutic Dentistry, Faculty of Continuing Education of Physicians and Pharmacists, Rep. Moldova, Chisinau In the last years, impaired ATM function is quite common in clinical dentistry practice. This requires to the dentists to pay more attention to diagnosis of these disorders and especially, the possibility of reaching an occlusal rehabilitation as the primary way for the stomatognathic system treatment. Since the development of neuromuscular dentistry is constantly growing, proposing new and modern methods of diagnosis and treatment of temporomandibular disorders, should be noted that the method of electronic axilografia and of the diagnosis of methods in articulator study have not lost their actuality. And the possibility of making a virtual 3D occlusion diagnosis, provided a tool to an exact study for the virtual occlusal correction using the occlusal breasts, orthodontic appliances, of the temporary and permanent restorations. The potential of modern CAD ​​/ CAM in the end is not revealed, being in a continuous process of improvement, which are now able to create accurate occlusal restoration by correlating parameters mandibulo-cranial occlusion of the stomatognathic system, after condylography.

INFLUENCE OF THE ALVEOLAR CONTOUR IN THE FINAL ESTHETIC OUTCOME Oscar González-Martín, DDS, MSc Adjunt Assistant Professor, Periodontal and Perio- Prosthesis Depatment, University of Pennsylvania School of Dental Medicine and University Complutense of Madrid, Spain

For natural appearance of prostheses placed in aesthetic areas, the preservation and/or reconstruction of the tissue volume seems necessary in many instances. Soft tissue, hard tissue, or combined augmentations may be attempted to reduce these defects, enhancing the alveolar contour at the edentulous segment. Also, while tissue volume at anterior implants is a key to aesthetic success, the adequate management of the provisional and definitive restoration become crucial to obtain optimal esthetic results. During this lecture we will discuss different surgical techniques to optimize aesthetic result, also describing the concept of the critical/subcritical contour and the role of abutment contour modifications at these zones on the peri-implant soft tissues, including the gingival margin level, gingival architecture and gingiva color.

AN ASIAN PERSPECTIVE OF THE CHALLENGES OF TISSUE MANAGEMENT AND LONG TERM ESTHETICS FOR DENTAL IMPLANTS Dr. Henry Ho Royal College of Surgeons form Edinburg - Prosthodontics and Implant Dentistry, Singapore The importance of bone and soft tissue stability to provide long-term health and esthetics for dental implants has been discussed extensively. The factors that allow this effect to occur have been identified. However, this effect has been discussed and observed only predominantly in the Caucasian population. The application of these factors however did not create a predictable situation in the Asia population. Therefore, it is the purpose of this presentation to provide the other necessary steps to create an acceptable long-term esthetics in a challenging Asia population similar to the thin gingival biotype described in the literature. 16-18 October 2014

AUGMENTATION OF EDENTULOUS ATROPHIC POSTERIOR MANDIBLE FOR IMPLANT SUPPORTED REHABILITATION Dr. Adrian Kahn DMD Specialist in Oral & Maxillofacial Surgery, Tel Aviv, Israel Adequate bone quantity and quality is a prerequisite for good esthetic and biomechanical result. In cases of severe alveolar ridge defects, augmentation is needed prior to endosseous implants placement. Several augmentation techniques can be employed in order to enhance the bone volume for proper implant placement. The edentulous atrophic posterior mandible represents today a great challenge for clinicians due to the lack of supporting bone and the presence of the inferior alveolar nerve in the surgical field. Vertical bone augmentation, short implant placement and surgical repositioning of the inferior alveolar nerve are treatment options that can provide a successful clinical result.

PERI-IMPLANTITIS: THE DISEASE OF THE FUTURE! Prof. Liran Levin Periodontist, Head of Research, School of Dental Medicine, Rambam Health Care Campus, Faculty of Medicine, Technion, IIT During the last years, the use of dental implants is becoming a common practice and peri-implant diseases are more frequently evident. Apparently, as time goes by and also implies from the available literature, we will be seeing more and more cases of peri-implant diseases. The reported prevalence in the literature reaches almost 30 to 50% of implant patients. This means that one out of two or three of our implant patients might present with peri-implant disease at some point. This is also an important aspect of informed consent for our patients. Another troubling issue with regards to peri-implant diseases is the lack of appropriate, well-documented gold-standard treatment, specifically for peri-implantitis. There are many suggested treatment options described in case reports and case series in the literature; none of them seems to provide a predictable long-term resolution of the disease. In order to prevent and treat peri-implant diseases, there is a need to understand the nature of the disease and the risk factors. 14 |

This lecture will focus on causes and risk factors for peri-implant diseases, ways to prevent its occurrence as well as the currently available treatment options for peri-implantitis.

HOW TO EVALUATE THE BEAUTY OF THE SMILE Prof. Adi Lorean School of Dental Medicine, Tel-Aviv University, Israel In the last decade rehabilitation of the oral cavity in conjunction with dental implants demands a great skill, knowledge and precision from the treating doctors. The new surgical techniques and technologies together with a better understanding are a key factor in our success .This lecture will try to reveal the connection of the surrounding tissues of the oro-facial architecture that influence and mark their impact on the beauty of the smile, the ultimate goal for us and for our patients.

THINKING OUTSIDE THE BOX IN MODERN IMPLANTOLOGY Prof. Ziv Mazor School of Dental Medicine, Tel-Aviv University Israel Alveolar ridge resorption leads to ridge atrophy making implants placement a difficult task. Rebuilding the existing atrophied ridge demands careful treatment plan often requiring 3D diagnosis and utilizing “outside the box” innovative treatment modalities. The lecture will incorporate this innovative thinking in patients who were told implants placement is practically impossible using conventional methods. Cases will be shown featuring step by step planning and execution.

Occusal performance of several commercial cad-cam systems – three years clinical experience and experimental model Prof. PhD Alexandru Petre Specialist in Dental Prosthetics, Bucharest, Romania ABSTRACT Prosthetic restorations that does not need intraoral occlusal adjustments are more a wish than a clinical reality of dentistry. The practical value of dental articulators is still controversial. Dental CAD-CAM systems have a high potential predictability. Zirconium oxide based ceramics appear to be a promising restorative material in terms of mechanical, biological and for the latest materials – aesthetic qualities. This presentation offers the author’s experience on the occlusal performance of zirconium-oxide based fixed restorations made by CAD-CAM technology using virtual articulator. Additionaly it shows a virtual model for assessing the consequences of variability in articulator mounting.

MAXILLARY SINUS AUGMENTATION: COMPLICATIONS, PREVENTION AND FUTURE Prof. PhD Dong-Seok Sohn School of Medicine, Catholic University of Deagu, Republic of Korea Sinus augmentation using variable bone substitutes has been known as predictable method to reconstruct the pneumatized sinus cavity for several decades. However various complications such as bacterial and fungal infection, oroantral fistula and failure of bone regeneration have been reported after bone graft was done in the sinus. Numerous studies reported successful bone formation and osseointegration in cases of sinus membrane elevation without bone graft. No bone added sinus augmentation is free from postoperative infection and the risk of cross-contamination according to studies. Only autologous bone reformation is achieved when bone is not graft in the sinus. This presentation will demonstrate new bone formation in 16 |

the sinus without bone graft using lateral window technique and crestal approach - hydrodynamic piezoelectric internal sinus elevation (HPISE) - with clinical, radiographic and histologic evidence from animal and human. Learning objectives: 1) Understand the predictability on new bone formation in the sinus without bone graft by clinical, radiographic and histological evidence from human and animal in lateral and crestal approached technique. 2) Understand the effect of replaceable bony window to seal lateral window on new bone formation in the sinus augmentation, compared to collagen membrane 3) Understand proper utilization of ultrasonic piezoelectric device for crestal and lateral sinus augmentation.

BIOLOGY BASED MODERN AUGMENTATION TECHNIQUES DMD Roland Török Dr. Roland Toroek, Nurenberg, Germany Diplomate ICOI, SRCOMF; Councilor of the SEUCC / SEHNOS Placement of endosseous implants in the atrophic jaw is often restricted because of a lack of sup- porting alveolar bone. To overcome this anatomic limitation, sinus lifting, bone block transplantation and GBR has become a common surgical procedure in oral implant treatment. This presentation will highlight through in depth clinical case documentation, the new and evolving role of instrumentation for access to the Sinus for Bone Augmentation and new a new method fort he GBR. Since the initial application of sinus lift augmentation, GBR and implant placement , many new approaches have been develloped, articles have been published describing predictable techniques with reliable long-term results. A knowledge of useful and clinically manageable techniques that provide access but minimize large surgical flaps are keys to success. We will see how to achieve successful results by creating bone in different regions of the jaw with osseointegration maintaining occlusal function under load.

DIRECT TECHNIQUES FOR RESTORATION OF ENDODONTICALLY TREATED TEETH – FIBER GLASS AND QUARTZ REINFORCED ENDODONTIC POST AND CORE SYSTEMS Lecturer PhD DMD Dana Cosac Titu Maiorescu University of Bucharest, Dental Medicine Faculty Restoration of endodontically treated teeth has been associated with the use of posts. Various post materials and designs have been introduced over the years. Motivated by the desire to conserve the remaining tooth structure and thanks to properties of modern adhesive systems, clinicians have re-evaluated traditional restorative dentistry and seek alternative methods to build up devitalized teeth. Direct restorations with fiber-reinforced post systems is becoming popular among clinicians because enlargement of the root canal space is not required and the risk of root perforation eliminated. The purpose of the paper is to present one of the many choices in restorative treatments which concern the direct reconstructions, using fiber glass and fiber-quartz reinforced endodontic posts and core systems. Direct restoration technique with fiber posts began to be used very often due to the biocompatibility, radiopacity, elasticity module very close to that of dentin, easy technique, their combination with dual cure composites permitting an homogeneous mechanical and physical-chemical reconstruction. They also satisfy with success the esthetical demands. Non restored devitalized teeth are structurally compromised and represent one of the greatest challenges for the clinician. Particular attention is paid to the incremental and curing techniques adopted to build up the restoration. Treatment modalities in restorative dentistry should be implemented with a solid rationale behind them and support from scientific studies. These principles, in conjunction with clinical experience, can dictate when and if a post is required when a tooth has undergone root canal treatment. Dentists know each tooth is anatomically different and should be diagnosed and treated with an individual approach when it comes to its restoration. Since their introduction in the late 1980s, the performance of these posts has delivered excellent clinical results, thus enabling the dentist to restore the involved teeth in a cosmetic and conservative manner. The reason for this success is directly related to fiber posts ability to absorb or dissipate the forces they will be under during function, thus reducing the stress on the root. Furthermore, it has been demonstrated that endodontically treated teeth are reinforced when bonded with these types of posts. 16-18 October 2014

VIRAL INFECTIONS IN THE ORAL CAVITY Lecturer, PhD, DMD Lelia Laurentia Mihai Titu Maiorescu University of Bucharest, Dental Medicine Faculty The oral mucosa  is  affected by many viral diseases, each giving rise to a specific clinical picture showing but common elements. The viral diseases can benign with  insignificant  signs, but may become severe in case of immunosuppression. In most cases, the oral lesions can present isolate localization and the others can be accompanied by skin lesions, with or without systemic manifestations. Viral infections can be  caused  by infectious agents, incapable of self-replication. This self-replication is done only at the expense of living cells that viruses invade them. Therefore, because the viruses are considered intracellular parasites, in order to reproduce they must penetrate the cells where they infect, through the cell membrane. The host cell is destroyed (cytopathic effect), and the viral particles are discarded in the extracellular environment and can infect other cells. Some types of viruses do not cause the death of infected cells, but limits themselves at their level remained dormant. Is the case of applicable herpes viruses and retroviruses of papilloma. When the balance is disturbed by a decreased immunity, stress or other triggers, viral infection becomes manifest. Recognition and diagnosis of viral diseases are important for specific treatment as well as for different etiologies of other similar events.

NON-SURGICAL METHODS IN BONE REGENERATION Assoc. Prof. PhD DMD Mihaela Raescu*, DMD Vladila Bogdan** * Titu Maiorescu University of Bucharest, Dental Medicine Faculty ** Dental Medicine Practice, Bucharest The usual conservative treatment methods concerning the periapical pathology consists in using antibacterial substances, calcium hydroxide, ozone-therapy, a.s. It is a fact that by using these methods the results can be obtained in a long period of time and sometimes are uncertain.The dimension of periapical pathology is the most important condition for a successful result.

THE MANAGEMENT OF PERIODONTAL DISEASE IN YOUNG PEOPLE AND CHILDREN Lecturer PhD Ruxandra Voinea Georgescu Titu Maiorescu University of Bucharest, Dental Medicine Faculty The periodontal disease is an important source of pain, aesthetic and masticatory disorders, discomfort and even loss of teeth in adults. Also, considering that it is a breeding ground for bacteria, it increases the risk for developing general cardiac, respiratory, renal disorders and not only. In other words, we could say that without dental and periodontal health, our general health is most of the times compromised, just like many systematic diseases give specific reactions at the level of the oral cavity. Twenty years ago, the manifestation of the periodontal disease was typical for ages of over 40. Today, this disorder is found more and more often at young ages, between 12 and 30. If these pacients are not treated accordingly from the beginning, they will become the proud owners of partial or even full dentures or they will develop general diseases, with their inherent psychologic and social effects. During the past decade, periodontology has become a true medical discipline. By capitalizing the progress made in microbiology, immunology, biomaterials, etc. a better knowledge of ethiopathogeny was gained, and differentiation of therapeutic methods was enabled. The management of diagnosing and treating this disease in young people implies interdisciplinarity. Imagistic, clinical and paraclinical investigations, personalized local treatment, and combining periodontal treatment with the orthodontic one are the latest treaments, and they bring solid and long-lasting results. Key words: Periodontal disease, interdisciplinarity, personalized treatment

PSYCHOLOGICAL IMPLICATIONS IN REMAKING OF THE ESTETICAL FUNCTION AT THE FULLY T OOTHLESS AGING PATIENTS Lecturer PhD DMD Ciavoi Gabriela*, Prof. PhD Dumbrava Vasile**, Prof PhD DMD Bechir Anamaria** * Medicine and Pharmacy Faculty, University of Oradea ** Titu Maiorescu University of Bucharest The purpose of paper is to study the modifications that produce in the psychological area of a fully toothless aging patient who’s estetical function will be rehabilitate. We studied the aging patient’s problem because this represent the majority of of the fully toothless patients and also presents psyhical and phisical caracteristiscs that are specific for the third age. Material and method: We studied 24 fully toothless patients, with age around 60-75 years old,from the urban medium, equally distributed on sexes.They had the anamnesis done and they talked to a psychologist.After remaking their estetical function (implant or mobile prothesis)the patients had another talk with the psychologist. Results were centralised around the raports we got from the psychologist. Conclusion was that remaking the estetical function of a patient increases some psyhical atributes such as self esteem, motivation, the wish to prelong life and also decreases anexiety.We can also conclude the fact that, in the results, we didn’t observe any significant diffrences between sexes.

Abstract. Removable dentures are a convenient and affordable solution for all social groups, especially for the underprivileged. We can rehabilitate any type of edentulism, Kennedy I, Kennedy II or interspersed gaps, with help of the removable denture or fixed prosthesis. Introduction: The favorable consequences of this type of prosthesis are largely determined by valueing the biomechanical, morphological and emotional conditions of each individual, taking into account several other factors. Purpose: In this paper we associate rehabilitation of mechanical function, aesthetics and phonetics with patients comfort by wearing a composite prosthesis. Material and Method: In this case study we present a 70 year old patient who came into our office for medical help. The patient was unhappy with both her aesthetics and mechanic functions of her dental arches. Results and Discussions: Because of economic matter, our patient denied the prosthetic work with implant treatment. We decided upon a more conservative treatment, using a composite prosthetic plan. Conclusions: The loss of morphological units over time arise aesthetic functional and social problems in young and old people. Therefore, prosthetic rehabilitation of the oral cavity can restore damaged functions. Oral rehabilitation in patients all ages lead to restoring social function, as well as quality of life. Key word: Removable prosthesis, Socio-economic aspects, old people

BONE SPLITTING METHOD IN THE CASE OF OSSEOUS RIDGESOF REDUCED DIMENSIONS (Case study) PhD stud. DMD Mihai Ionuţ Daniel*, DMD Mihai Roxana**, Assoc. Prof. PhD DMD Elena Despa, Prof. PhD DMD Doina Lucia Ghergic * *Faculty of Dental Medicine, Titu Maiorescu University, Bucharest **Selarl de chirurgien dentistes Daniel et Roxana Mihai, France Abstract: Introduction: In the case of patients with reduced vestibular-palatal or vestibular-lingual ridges with a dimension under 3-4 mm, in order to allow the insertion of endoosseous implants, we are forced, more than often, to resort to osseous grafts. The bone splitting method allows, with the help of piezosurgery tools, to increase the intracortical distance and to regenerate the bony structure in a guided way, with a success rate up to 98%. Material and method: The bone splitting method was used in the case of 65-yearold female patient, who, at the level of 22, had internal radicular resorption with mobility of III degree. The patient asked for both a provisory as well as a permanent aesthetic solution regarding the replacement of 22 after extraction. Therefore, we used the 3D scanner in order to determine the osseous dimension necessary for an implant insertion and, as a result of the clinical examination, the patient had an intracortical vestibular-palatal dimension of 3 mm. In this clinical study, the decision was to augment the ridge through the bone splitting method and to insert a 3.7 mm implant in diameter and 8 mm in length at the level of 22 area. Conclusions: During the same visit we performed the extraction, the bony augmentation of the ridge, the insertion of the implant and a provisory crown was cemented. As a result of the augmentation, the intracortical diameter increased from 3 mm to 5 mm and the patient was given a permanent prosthesis 2 month after implant insertion. Key words: endoosseous implant, osseous augmentation, bone splitting method.

GUIDED IMPLANTOLOGY AND ITS EFFECT ON AVOIDING OSSEOUS GRAFTS (Case study) PhD stud. DMD Mihai Ionuţ Daniel*, DMD Mihai Roxana**, Assoc. Prof. PhD DMD Elena Despa, Prof. PhD DMD Doina Lucia Ghergic * *Faculty of Dental Medicine, Titu Maiorescu University, Bucharest **Selarl de chirurgien dentistes Daniel et Roxana Mihai, France Abstract: Currently, guided implantology allows the use of a software that helps the practitioner to obtain a surgical guide in order to insert implants in areas rich in osseous offer and, therefore, he/she can renounce osseous grafts. Introduction: A 38-year-old male patient came to the dental office. He needed a speciality implant-prosthetic treatment. As a result of the endo-oral clinical and radiological examination, we noticed the occurrence of bilateral edentation of the upper canines, with two 13-year-old temporary bridges. The two upper canines were in palatal position and the dentist preferred extraction and not the orthodontic treatment. The patient recalls that, over time, there were multiple episodes of decementation of the two temporary dental bridges and also episodes of dentinal sensitivity in contact with physical stimuli. He also recalls that each recementation was followed with multiple interventions on aggregation elements or on pillar teeth. Subsequently, there were performed study photos, impressions of the study and the 3D scanner was used. The proposed solution by the dentist previously was to insert two endoossesous implants after an initial autogenous graft with iliac crest assay. Conclusions: In this clinical study, we proposed the building of a surgical guide used in Simplant software, having as purpose the insertion of two Zimmer TSV implants with 13 mm length, without appealing to the osseous procedure initially proposed for the two implants. In our case, the permanent prosthesis was performed two months after the successful insertion. Key words: guided implantology, surgical guide, autogenous graft.

THE ETIOLOGY OF HIGH CARIOACTIVITY IN MIXED DENTITION Lecturer PhD DMD Ane-Marie Stancu Titu Maiorescu University of Bucharest Abstract The aim of the study was to assess the causes of increased carioactivity of a group of 30 patients aged 6-11 years. Material and methods: To assess causes increased carioactivity designed questionnaires were used to investigate the antecedents family history, medical history, physiological and dental history. They were filled with parents and patients (eating habits, hygiene), in the presence of the doctor, his role is to clarify any issues or concerns. Results and discussion: Following analysis of the questionnaires, it was found that when grown carioactivity drives a plurality of at least two factors, the worst forms manifested when overlapping all three determinants of dental caries at the same intensity. Another important issue in patients with increased carioactivity is the absence of systematic visits to the dental office or making them just in case of emergencies. Conclusions: Thorough evaluation of these cases, not only clinically and laboratory but also in terms of history and customs allow an individualized plan prophylactic, therapeutic and periodically control.

ORAL MUCOSAL LESIONS INDUCED BY THE CONTACT WITH DENTAL ALLOYS Prof. PhD Șerban Țovaru*, Prof. Ass. PhD stud. Carmen Gheorghe*, Prof. Ass. PhD stud. Ioanina Pârlătescu*, Lect. PhD Lelia Laurenția Mihai** *UMF Carol Davila of Bucharest ** Titu Maiorescu University of Bucharest The edentations due to loss of teeth impose restorations by prosthetic devices. The dental alloys are not completely inert and allow the release of ions which sometimes leads to mucosal changes. Of these,in current dental practice, most frequently seen are amalgam tattoos visible at the fillings contact, lichenoid reactions occurring near the dental bridges, mucosal pigmentations due to metal contact in restauration. Dental amalgam is an alloy composed of liquid mercury and a powder containing silver, tin, copper and zinc in varying proportions. The presence of local contributing factors (chronic inflammation of the oral mucosa or gingival and periodontal disease, a particular salivary composition, the act of chewing) or general (atopic nature - hipersensibility to constituents of dental alloys) in certain patients promotes migration and deposition of ions in the lining alloy structure. The clinical aspect of these lesions may be different from pigmented patches of various shades of color depending on the contained alloys, up to reticular keratotic lesions that mimic the clinical appearance of an idiopathic lichen planus. The evolution of these types of injuries is different, lichenoid lesions can disappear in a period which varies from six months to one year after removing the device, while pigmented lesions persist indefinitely. Further research on this topic has as main objective the development of dental alloys chemically stable not allowing the release of ions in saliva and mucosa.

PhD Violeta Hancu*, Lect. PhD Raluca Monica Comăneanu*, Lect PhD Alina Ormenişan**, Prof. PhD Doina Lucia Ghergic* *Titu Maiorescu University of Bucharest, Dental Medicine Faculty **UMF Târgu Mureş, Dental Medicine Faculty The partial edentation is one of the most frequent encountered oral pathologies, its restoration being usualy made with integral/partial physiognomical fixed prosthesis. The incorrect execution or choice of the dental materials to be used for the manufacturing of the restoration, lead to the occurrence of multiple effects. The aim of our study is to analyze the negative effects on a group of patients, generated by the insertion in the oral cavity of prosthetic restorations incorrectly manufactured or adjusted. Material and methods: The study was made on a group of pacients, whose partial edentations have been restored, pacients who addressed theirselves to a number of three different dental offices in Bucharestand Târgu Mureş, in the period of October 2012 – June 2014. The pacients were classified according to age, gender, the location of the edentation, its etiology, the success or the failure of the prosthetic treatment and the type of the iatrogenic observed. Results and conclusions: The study group consisted predominantly of female patients belonging to the 50-59 years age group. Percentage of iatrogenic detected in the study group was 19.14%. The most common problems are incorrect fillings of rooth canal and including an insufficient number of teeth.

Restoring teeth with coronary destructions and rebuilding dental arches continuity interrupted by loss of periodontal dental units benefit more often nowadays the fixed metal-ceramic prosthesis. Prosthetic treatment success depends on developing a full diagnosis, the development of a treatment plan properly phased and individualized for each clinical case and the rigorous execution of all technical phases of clinical which includes metal-ceramic technology prosthetic reconstructions. Material and methods: We performed the analysis by electron microscopy and X-ray spectroscopy energy dispersive (EDS) of a metal-ceramic crowns CoCr with physiognomic component substrate represented by Hera Ceram ceramics with a scanning electron microscope SEM model Philips XL 30 TMP, equipped with an EDAX spectrometer energy as to detect any defects. Results and conclusions: We found from the study that the porcelain layer is not deposited uniformly. At a magnification of 2000x detect the presence of surface defects casting. Since the thermal cycles occur at elevated temperatures is obtained diffusion of the elements is different to the metal layers deposited between the ceramic layers deposited in succession, thereby creating a bond between the layers of porcelain.

A CLINICAL STUDY OF THE RELATIONSHIP BETWEEN BURNING MOUTH SYNDROME AND ALLERGENS FROM THE DENTAL MATERIALS PhD stud. Elena Claudia Coculescu*, Prof. Ass. PhD Stud. Ioanina Părlătescu*, Prof. Ass. PhD Stud. Carmen Larisa Gheorghe*, Prof. PhD Şerban Ţovaru*, Prof. PhD George Sorin Siplică**, Lect. PhD Bogdan-Ioan Coculescu*** *Faculty of Dental Medicine, University of Medicine and Pharmacy Carol Davila, Bucharest **Faculty of Medicine, University of Medicine and Pharmacy Carol Davila, Bucharest ***Faculty of Medicine, Titu Maiorescu University of Bucharest

Introduction: Burning mouth syndrome (BMS) is defined as a chronic pain condition characterized by a burning sensation in clinically healthy oral mucosa. Incidence Incidence of BMS diagnosed and treated in the Department of Oral Medecine - Oral Pathology Dental, Faculty of Medecine, University of Medicine and Pharmacy „Carol Davila” Bucharest is 16,23%. As it was 20 years ago, the etiology of BMS is considered nowadays multifactorial. Objective: To evaluate the role of allergens from the dental materials in the etiology of burning mouth syndrome. Materials and Methods: For this study 36 patients with the diagnosis of burning mouth syndrome (BMS) were selected. They were consulted in the period November 2013-May 2014 in the Department of Oral Medicine, Faculty of Dentistry, Bucharest, Romania. In the Dermatology Department of the Clinical Hospital Colentina, Bucharest, the patients were tested with DS-1000 test kit (allergic epicutaneous tests), which includes 31 kits dedicated to materials commonly used in dentistry. The interpretation of the results was made at 48 and 72 hours, using a visual scale included in the test kit. Results and Discussions: Positive reactions occurred in 12 women with a mean age of 57 years and 4 men, with mean age 47.75 years. The positive reactions (n=11) were noticed to these substances: Potassium dichromate, cobalt (II) chloride hexahydrate, Sodium tetrachloropalladate (II) hydrate, Gold (I) sodium thiosulfate dihydrate, Nickel (II) sulfate hexahydrate, Tin (Tin), Copper ( II) sulfate pentahydrate, Palladium (II) chloride, Urethane dimethacrylate, ethylene glycol dimethacrylate, 16-18 October 2014

dimethylaminoethyl methacrylate. A.C, female, 40 years with BMS symptoms and positive reactions to allergens no 10 (++), 12 (+), 14 (+), 15 (++) and 31 (+), with DS-1000 test kit (allergic epicutaneous tests). (where 10 = Potassium dichromate, 12 = Cobalt (II) chloride hexahydrate, 14 = Gold (I) sodium thiosulfate dihydrate, 15 = Nickel (II) sulfate hexahydrate and 31 = Sodium tetrachloropalladate (II) hydrate). The most frequent allergen was Sodium tetrachloropalladate (II) hydrate which was positive in 11 patients, followed by Potassium dichromate positive in 5 patients; Gold (I) sodium thiosulfate dihydrate and cobalt (II) chloride hexahydrate positive in 4 cases; Tin (Tin) and Palladium (II) chloride in 2 patients; Nickel (II) sulfate hexahydrate, Copper (II) sulfate pentahydrate, Urethane dimethacrylate, ethylene glycol dimethacrylate, dimethylaminoethyl methacrylate positive in one patient. An argument that BMS is caused by dental materials allergy is that the majority of positive reactions in study group were to compounds that are not common, such as Palladium, Chromium and Cobalt. Positive reactions to these haptens are rarely quoted in similar studies. Other authors confirm positive reactions to haptens such as Nickel, Mercury, Gold and Thiomersal. The fact that the majority of positive reactions in the tested patients with BMS were to Palladium, Chromium and Cobalt can only confirm the strong association between their disease and allergy. The source for these compounds can only be in the patients’ dental fillings, while the small percent of allergies in the control group was to common compounds such as Nickel and Gold. Conclusions: From all possible causative factors of BMS, a significant role is played by contact allergic reactions to dental material. The therapeutical approach based on removal of the etiological cause will bring good results. Selective References 1. Coculescu E.C., Ţovaru Ş., Coculescu B.-I.
