Abstract:
Bad breath, foetor ex ore or halitosis originates in 85% of the cases out of the oral cavity, although still a large public majority believes it comes out of the stomach. The remaining 15% can come out of the ENT region (10%) or from several systemic disorders (5% - so including the stomach/gastrointestinal tract).Oral bacteria are at the origin of the problem. A clear correlation with chronic periodontitis has been found. Several oral niches play a role in the housing of these bacteria, of which the dorsum of the tongue is of utmost importance.Detection can be performed physical (organoleptical) of by machinery (chair-side or in a laboratory). The treatment consists of 2 approaches: (1) the in-clinic cleaning of the oral cavity, including the tongue and (2) the at-home maintenance instructions. In case of periodontitis, the whole periodontical protocol should be followed. 90% of the halitosis cases can be treated successfully, although a lifelong good oral hygiene has to be performed!Moreover, we are often confronted with cases of pseudo-halitosis or even halitophobia. These patients need a special approach and are better of by a multi-disciplinary setting for their problems (including psychological support). Otherwise these patients continue “shopping†from clinic to clinic and from specialist to specialist…

Abstract:
Success in endodontic treatment is based on the equally important triad of debridement, disinfection, and obturation. When a step in the endodontic or restorative procedure is inadequate, apical seal is adversely aff ected. Th e ultimate goal of endodontic obturation has remained the same for the past 50 years: achieve a fl uid-tight seal of the root canal system, from the coronal opening to the apical termination. Th ree-dimensional obturation of the radicular space is essential to long-term success. For this purpose, several techniques have been advocated for obturation. An ideal fi lling technique should assure complete fi lling of the canal without overfi ll and with minimal or no voids. Th us, it is important to select an obturation technique that off ers consistency and is easy to use. Most of obturation studies show that all materials and techniques result in some degree of microscopic voids. Although a poorly obturated canal and voids are correlated, radiographic evaluation of obturation does not correlate well with obturation imperfections. An adequate radiographic appearance of the obturation does not confi rm an adequate seal. Fortunately, clinical success rates aft er endodontic treatment are high despite the varied conditions, materials, and techniques employed. Our presentation will review obturation techniques and evaluation methods and discuss actual success rate in endodontic treatment based on clinical reliable studies.

Abstract:
The periodontal ligament, that connects the root of the tooth to the jaw bone, contains many mechanoreceptors that encode tooth load when subjects contact and gently manipulate food with the teeth. Tooth loss will remove these receptors and reduce the intra-oral neural input to the brain. The rehabilitation ofedentulism by means of endosseous implants leads to an improvement in the sensory and motor functions but fail to reach the same level of sensitivity as dentate subjects. Patients with a lower limb prosthesis anchored by a percutaneous osseointegrated implant reported that this allowed them to feel the kind of soil they walked on. Th is sensory improvement coined ‘osseoperception’ was defi ned as a perception of external stimuli transmitted via the implant through the bone by activation of receptors located in the peri-implant environment, the periosteum, the skin, the muscles and/or the joints. Hence, it remains uncertain whether this improvement can be ascribed to neural endings in the implant-bone interface itself or to intraosseous neural endings (‘osseoreceptors’) located further either in the bone marrow or above in the periosteum. Histological, neurophysiological and psychophysical evidence of osseoperception is available. Yet, from the current evidence it remains unclear whether an altered innervation (from periodontal to peri-implant) may have changed the tactile function of implant-rehabilitated sites. The identification of the possible sensorimotor cortical adaptive processes that may be associated with the loss of teeth and their replacement by endosseous implants has beenalso explored by functional magnetic resonance imaging (fMRI). Th is presententionwill describes, at a cortical level, the basis of tactile osseoperception aft er tooth replacement by a boneanchored implant. It will also elucidate other neurophysiological aspects of oral implants, such their refl ex function, and point out their clinical meaning.

ShePublished more than 10 papers in reputed journals
Abstract:
Treatment of the edentulous patients poses a number of challenges. Expectations regarding the esthetics of the defi nitive prosthesis may be high. The treatment of completely toothless patients using oral implants does not always allow the insertion of adequate number implants to ensure a fi xed construction, the reasons ranging from anatomical, or health restrictions to fi nancial limitations. Multiple surgical approaches are available in order to provide this type of treatment such as sinus graft ing, maxillary osteotomies as well as horizontal augmentations. The loss of teeth and use of a removable prosthesis can result in continued alveolar bone atrophy in both the vertical and horizontal dimensions. Th e use of dental implants to stabilize dentures has proven to be successful for many people, these include decreased bone resorption. This presentation presents a simplifi ed surgical and prosthodontic’s approach. Although we discuss the many advantages of implant-supported overdentures.

Title: The diagnosis of mandibular midlingual foramen and the chin relationship by Computed Tomography scan
Time : 13:50-14:10
Biography:
Chia-Ming Ho has completed his D.D.S. at the age of 26 years from National Yang-Ming University in Taiwan and M.S. from Johann-Wolfgang Goethe (Frankfurt) University in Germany. He is the instructor of TIDER (Taiwan Institute of Dental Education and Research) and the director and diplomate of APAID (Asia-Pacifi c Association of Implant Dentistry).
Abstract:
Nowadays, as the long term success and the survival rate of dental implants are growing up, implant surgery is largely regarded as a safe and minimal invasive procedure when meticulously planned and carefully performed, especially at the lower anterior region. However, implant placement and chin bone harvesting procedures, as any other surgical procedures, are not free of inherent risks. These years, there are more and more articles which discussed the neurosensory disturbance including pulpal canal obliteration, negative pulpal sensibility, and postoperative paresthesia aft er mandibular symphysis bone harvesting procedure. To be compared with harvesting autogenous bone blocks, implant placement at mandibular symphysis is a minimally invasive surgery. Nevertheless some articles revealed that implant placement at mandibular symphysis may cause not only neurosensory disturbance, also life threatening scenarios. One of the fetal risks is severe haemorrhage in the fl oor of the mouth with subsequent life threatening upper airway obstruction have been recorded in association with implant placement in both the anterior and posterior mandible. In order to avoid the life-threatening complication, such as severe haemorrhage in the fl oor of the mouth with subsequent upper airway obstruction aft er implant placement or chin block harvesting. Th e aim of this study is (1) to bring to the attention of the clinician this extremely important anatomic structure which may cause potentially fatal complication, (2) to determine the location and incidence of the mandibular midlingual foramina by direct measurement on human dry skull and CT images (3) to analyze the diff erence between diff erent data banks.
Pamela Uribe

Title: Clinical predictors for permanent maxillary canine impaction: A novel approach using a multivariate data analysis.
Time : 14:10-14:30
Biography:
Pamela Uribe completed her DDS degree at CES University, MedellÃn, Colombia in 2012. Currently, she is a PhD student at the Department of Orthodontics, Sahlgrenska Academy, University of Gothenburg, Sweden. Her research interests include the pathogenesis of impacted canines, molecular characterization of the dental follicle, and bone biology.
Abstract:
Background: Ectopic eruption and impaction of maxillary permanent canines is a frequently encountered clinical problem. A number of studies have been conducted in order to fi nd possible predicting/predisposing factors. Conventional univariate statistics have been used in these studies, which have led to disperse and potentially inaccurate results. Multivariate data analysis (MVDA) is a powerful tool for integration and interpretation of complex datasets, which can be used to avoid high numbers of false positives predictors. Aim: To fi nd possible predicting factors for impacted canines by using a comprehensive multivariate approach. Subjects and methods:Th is retrospective study included all patients referred for surgical exposure of impacted canines (n=45) to Mölndal Hospital, Sweden, during 2011. Age- and gender-matched orthodontic patients (n=45) with normally erupting canines were used as a control group. Th e age range for both groups was 11-17 years. Position of the canine (OPG radiographs), skeletal variables (profi le radiographs) and dentoalveolar traits (casts) were evaluated as possible predicting/predisposing factors for impaction. A MVDA was performed using SIMCA (MKS Umetrics, Sweden). Results: Th e vertical level and lateral distance of the impacted canines were positively correlated to impaction. None of the parameters evaluated either with profi le x-rays or casts were associated to impacted canines. Conclusion: Th e only factor that could be identifi ed as a positive predictor for impaction, using a MVDA approach, was the position of the impacted canine. Neither the profi le x-ray analysis nor the study cast analysis is adequate to predict canine impaction. Non-clinical parameters potentially associated with the etiology of impacted canines, such as inheritance and molecular factors regulating the eruption process, should be investigated in future studies. Clinical implication: A clinical examination of the canine eruption path at DS2M1 is recommended, and should be complemented with radiological and regular clinical supervision when ectopic eruption of the maxillary canine is suspected.

Abstract:
Aim: The study was conducted to apply a new three dimensional method of analysis for comparison between the eff ects of two diff erent methods of distalization of the maxillary fi rst molar. Materials and Methods: Cone beam computed tomographic radiographs of 20 patients suff ering from class II malocclusion were selected from the outpatient clinic data library of Department of Orthodontics, Faculty of Dentistry, Minia University. Half of them had been treated with Carriere distalizer and the other half were treated with the dual force distalizer. Th e pre and post distalization C.B.CTs were analyzed three dimensionally using the united reference method. Linear and angular measurements for the maxillary fi rst molar and the maxillary canine were taken to evaluate the performance of both distalizers. Loss of anchorage was also evaluated through linear and angular measurements performed for the mandibular fi rst molar and the mandibular central incisor in case of Cariere distalizer while only linear measurements were performed for buccal and palatal screws heads in case of dual force distalizer. Results: Maxillary fi rst molar distalization, intrusion, distal crown tipping, lingual crown inclination and mesial out molar rotation were assessed among both distalizers. More bodily movement and lesser rotation in usage of dual force distalizer were detected. Loss of anchorage indicated by mesialization and extrusion of mandibular fi rst molar and buccal crown inclination of mandibular central incisor in usage of carrier distalizer and mesial movement of buccal and palatal screws heads in usage of dual force distalizer was observed. Conclusion: The united reference method is an eff ective three dimensional evaluation method for treatment progress

Abstract:
Objectives: The aim of this study was to characterize the the Mandibular median Lingual Foramen region using cone beam computed tomography (CBCT) to clarify its morphology and variations that take place. Materials and Methods: A retrospective study of the Midline lingual canal was performed in the transverse and sagital planes of 111 CBCT. Inclusion criteria were: patients older than 18 years and no artifacts or pathologies that would interfere in the evaluation. The variables measured were: A, length of the outlet duct. B, distance from the canal to the vestibular cortical. C, distance from the canal to the inferior cortex, D: distance from the canal to the lingual cortical. E, distance to the alveoli of the tooth nearest dentate patients, and crest in edentulous patients. F, angle of the duct to the horizontal. G, diameter. H, output level of the socket in relation to the teeth and presence of bifurcations Results: A total of 111 CBTC were analysed. 83 were of dentate and 28 of edentulous patients. In the Mandibular median Lingual Foramen region, a single canal was observed in 63%, 2 canals in 33.3% and a triple foramens in 2.7% of patients. Females showed slightly lower values than males for each of the analysed variables, with statistically signifi cant diff erences in the length of the canal in edentulous (p=0.029) as well as in dentate (p=0.027). Conclusion: Dental CBCT demonstrates the presence of the lingual vascular canals, their frequency, number, and size being of great importance for planning surgical procedures.

Abstract:
Background: Reduced vertical bone level in the implantation area is oft en considered one of the limiting factors before implant insertion. Inserting implants of reduced length might be useful in order to avoid vertical bone augmentation prior to implantation. Th e use of short implants in compromised sites are considered an alternative procedure to avoid extensive surgical procedures such as sinus lifting and grafting. Methods: 40 short dental implants (4.8 and 6.2 mm diameter with 5 and 7 mm diameter). fixtures were installed on 20 bovine rib blocks. Th e primary stability of the implant was measured by the resonance frequency using an Osstel ® device. Th e removal torque values (RTV) of the implants was assessed using a Digital torque gauge instrument. Results: Both 4.8 and 6.2 mm wider implants showed marginal increase in resonance frequency and removal torque values with 5 and 7 mm implants. However when the comparison was done between the two implants with different diameter a significantly higher primary stability was observed with 6.2 mm diameter implants. Conclusion: From the observations of the study it can be concluded that short implants were able to achieve desirable primary stability. Th e primary stability substantially improved with short implants with wider diameter.

Abstract:
Assuring a high standard in the quality of care delivered is an important goal for every practitioner. Quality Assurance (QA) is the systematic monitoring and evaluation of various aspects of care. Implementation of a suitable QA program involves developing criteria based on acceptable standards of care and professional ethics. Analyzing such criteria to determine weaknesses helps achieve Quality Improvement (QI). QI in health care refers to revising current standards of care to make changes that are confluent with improved patient outcomes and system effectiveness. Th ere are several strategies to ensure QI in a dental clinic. Use of various checklists, encouraging certification, obtaining accreditation and ensuring proper credentialing of employed professionals are the most common ones. For many years, policy makers and regulators in the United States have pushed toward mandatory accreditation for hospitals and allied health schools. Dental personnel would benefit from being aware that office procedures may soon come under such a radar.It is in this respect, that accreditation as a Dental Home for a general dental practice has received considerable attention. Th e Dental Home is an ongoing relationship between the dentist and the patient, based on oral health care delivered in a comprehensive, continuously accessible, coordinated and family-centered way. Th is synoptic review will discuss the feasibility of accreditation as a Dental Home by enumerating its requirements, benefits, limitations and recommendations, thus jointly addressing the current trend towards accreditation of facilities and marked interest in the concept of Dental Homes.

Abstract:
Dental Radiology is a vital diagnostic tool which is essential in a dental practice. Recent studies have shown that 25 % of radiological examinations occur in dental clinics in the European union . These radiological examinations are most commonly performed on children and young adults , which makes it even more fundamental for dental practitioners to be informed about its harmful effects. Th e purpose of this study is to assess dentists knowledge regarding radiological practices. Th is study was conducted to enquire about perceptions in radiology and its harmful effects amongst the dental community practicing in the UAE. 220 questionnaires were distributed to general practitioners and specialists working in dental clinics in UAE. Surveys contained questions regarding basic concepts in radiology, radiation protection devices were some of the questions that were asked for patients exposed to radiation and staff handling x rays. Result analysis showed that 89 % of dentists find radiographs most useful for initial diagnosis. The results further showed that 75 % of dental clinics iseintraoral periapicalradiographs , followed by panaromic radiographs ( 44%) and bitewings (40%). Th is is followed by the conventional method used in 32.8% of dental clinincs . There were 29.1% of the dental clinics which made use of both conventional and digital radiography. 78.8% of respondents are aware of radiographic protection devices . 63.2 % of dental clinics provide patients with a lead apron for radiation protection.

Abstract:
Dental implants being the hallmark of dentistry nowadays, is oft en a challenge especially in patients with either or all of excessive alveolar bone resorption, traumatic extractions and over pneumatized maxillary sinus. Th e literature is quite rich in the graft materials used for open sinus lift procedures, however, the modifications in technique where not as such. Whether the science in this area is lead by research or by manufacturers, is obscure; however, the piezo-surgical instruments have been favored for open sinus lift techniques for their higher safety. Th ere is also abundance of sinus lift kits from all over the world.Th e introduced technique will eliminate the need for special sinus lift kits, provide an easier approach to the floor of the sinus and facilitate the placement of graft materials (blocks or discs).

Abstract:
Usually, Patients with cancer encounter assaults on their oral health from both the disease and the treatment option. While most of these are manageable, complications can have a profound impact on quality of life. Compromised oral health prior to, during, and following cancer therapy can affect treatment outcomes. Despite the significant advances in the cancer therapy which had a great impact on prolonging the survival rate, these patients are potentially at high risk for developing a number of oral complications, ranging from acute oral complications including oral mucositis and infections, to late complications including hyposalivation, caries, taste changes, trismus and jaw osteonecrosis. Cancer survivors, depending on the specific cancer and modalities of therapy, may remain at life-long risk of developing oral complications which require increased awareness and recognition to promote prevention and appropriate intervention as well as long-term dental follow-up aft er completion of cancer therapy. It is therefore important for the primary oncologist and the dentist to be aware of these complications. Prevention and management is best provided via multidisciplinary health care teams, which must be integrated and communicate effectively in order to provide the best patient care in a coordinated manner at the appropriate time. Patients should typically undergo thorough oral examination prior to initiation of therapy, during and aft er therapy to identify any active infection. Th e aim of this presentation is to discuss potential oral complications as a result of cancer therapy and their management and what are certain precautions we should be aware of for these patients.

Dailey “Biostatistics for Oral Healthcare,†published by Wiley-Blackwell Publishing, which is recognized as the most comprehensive biostatistics book for researchers and students in dental science.
Abstract:
The goal of the study is to assess the level of misused statistics in dental research, and identify the major source of statistical errors that are prevalent in dental literature. Misuse rate in dental literature is compared with that in medical literature. Th e total of 418 papers, published between 1995 and 2009, was randomly selected from 10 dental journals. Every paper in the sample underwent careful scrutiny for the correct use of statistics. Of these, there were 111 papers that can’t be determined whether or not the use of statistics is appropriate, due to insufficient information presented in the paper. Removal of these undetermined papers from the further consideration left 307 papers for the study. A paper with at least one statistical error has been classified as “misuse of statistics,†and a paper without any statistical errors as “acceptable.†Statistical errors also included misinterpretation of statistical results. To assess the misuse rate, the number of papers that contained at least one statistical error was counted. From the sample of 307 papers, our investigation showed that 149 were acceptable and 158 contain at least one misuse of statistics. Th is resulted in the misuse rate of 51.5% for dental literature that is lower than that reported by several studies done for medical literature. Th e improper use of statistical methods and data analysis could cause irreparable harm to the patients as the wrong analysis can lead the investigators to inappropriate conclusions that could be clinically detrimental. Th e major source of statistical errors discussed in this presentation should help reduce the potential misleading conclusions that might cause clinical mistakes. In this presentation 8 most common statistical misuses in dental research will be discussed. Th ese 8 misuses account for approximately 80% of the total statistical errors in our study.

She has published extensively and has presented at national and international meetings on the issue of oral health and quality of life.
Abstract:
Objectives: This multi- center study was aimed to assess how the burden of caries and malocclusion independently affects the Oral Health Related Quality of Life (OHRQoL) of Latino children/adolescents living in the US, Peru and Mexico Methods: A total of 2000 students aged 12 to 19 years were recruited from the US, Peru and Mexico in six different sites. Th is study was a collaborative effort between four universities. Our sample was representative of various socioeconomic levels and populations densities in each country. Th e Child Oral Health Impact Profile (COHIP) was utilizes to assess the OHRQoL. Caries was quantified utilizing the Decayed, Missing and Filled Surface index (DMFS) and malocclusion using the Index of Complexity, Outcome and Need (ICON). We also evaluated the cross-sectional concurrent validity of the COHIP in each participating country. Results: A significant decrease in OHRQoL was detected in relation to Malocclusion Treatment Need in Mexico, Peru, and the US. However, this was not consistently reflected in the COHIP subscales across sites. Only Social/Emotional Well-Being appears to be a significant contributor (P=0.04) to the decrease. An increasing burden of caries appears to significantly decrease OHRQoL. It is not clear which subscale contributes to this decrease. In rural and indigenous population, caries and malocclusion had not effect on OHRQoL. Students living in urban setting experienced a linear relationship between malocclusion severity, caries experience and OHRQoL. Overall, the COHIP appears to be concurrently valid in each country (P<0.01). Conclusions: Th e overall analysis of the sample shows an apparent effect of caries and malocclusion in OHRQoL of Latino students. However, the difference of this effect between rural/indigenous and urban samples demonstrates that acculturation and demographic settings may modify the effect of caries and malocclusion in OHRQoL.

Dr. Li is a 2000 graduate of China Medical College in Taichung, Taiwan, and is the fi rst graduate student in 2011 of the MOI program at Goethe University in Frankfurt, Germany. He was an invited participant of the 14th Dentsply Friadent World Symposium 2010 in Barcelona, Spain. Dr. Li was chosen by Business Week magazine as one of the top one hundred dentists in Taiwan. His clinic, opened in 2004, has nine units, two Cone Beam CT scanners, and is staffed by four dentists and twelve assistants.
Abstract:
Trephine explantation is an effective method to retrievean osseointegrated implant, but the bone destruction is obvious. In recent years, there are more and more tool kits on the market focusing on removing failed implants (e.g. Noble Implant Retrieval Tool; BTI Implant Extraction System) without significant bone destruction. However, in the case of solid morse taperabutment fracture(e.g. ANKYLOS standard abutment), the kit cannot engage the implant inner surface to reverse the implant from the bony socket. In this situation, the method presented by Li C.H.&Chou C.T. is a good way to deal with the problem.Furthermore, it is preferable to trephine because it will preserve the bony socket and allow for immediate reimplantation.

Abstract:
The revival of the lost periodontium using therapeutic measures have always been the unceasing objective since decades. Root bio modification agents have been used as an adjunct to periodontal regenerative therapy targeting to demineralize the root surface, thereby providing a matrix which supports periodontal regeneration. Recently, maleic acid has been used as a smear layer removal agent in the field of Endodontics. Hence, the aim of the present study was to evaluate the use of maleic acid as a root bio modification agent and to compare it with three other root conditioning agents for its effectiveness. Method: Twenty extracted single rooted human teeth were selected. Each tooth was decoronated and the apical portion of the root was cut, so as to preserve the mid root portion. Th en, the specimens were randomly assigned to four groups of 10 fragments each according to the demineralizing agents used. Group1 (Citric acid) – application of 50% citric acid, pH 1 for 3 minutes. Group 2 (EDTA) – application of 24% EDTA, pH 7, for 3 minutes. Group 3 (Maleic acid) – application of 7% maleic acid, pH 1.3 for 3 minutes. Group 4 (Control) – application of saline for 3 minutes. Scanning electron microscopy was used to check the presence of residual smear layer and the patency of the dentinal tubules along with fi broblast cell attachment on the cemental surface aft er treatment with the root conditioning agents . Th e results of this study demonstrated that at the 3 min time interval, Maleic acid group, removed 70% of smear layer compared to Citric acid ( 50%) and EDTA ( 30%). Also, all the three experimental groups showed signifi cant fi broblast cell attachment compared to control group. Hence, this study provides suitable information regarding the use of Maleic acid as an denovoagent for root biomodification.

Abstract:
The anatomical variations of root canals may cause furcation perforation during endodontic treatment. In the event of perforation, the area is covered with a repair material that provides a tight seal between the periradicular tissues and the oral environment. The aim of this study is to evaluate the success of Biodentine as a furcation perforation repair material. For this propose 50 cubic Biodentine samples (1cm3) were prepared. Five experimental groups were established: Group 1 (samples 1–10) was exposed to distilled water; Group 2 (samples 11–20) to 5.25% NaOCl; Group 3 (samples 21–30) to 17% EDTA; Group 4 (samples 31–40) to 2% CHX; and Group 5 (samples 41–50) to ozonated water. All samples were exposed to irrigating solution for 7 days and then they were washed with distilled water for five minutes. Next microhardness testing and surface roughness testing were applied to all speciments. The data were evaluated using SPSS 15.0 soft ware. The signifi cance level was set at 0.05. Microhardness values significantly diff ered among the groups (P<0.05). Pairwise comparisons of microhardness values showed differences between the following groups: 1-2, 1-4, 1-5, 2-3, 2-5, 3-4, and 4-5. Th ere were no diff erences between groups 1-3, 2-4, and 3-5. No statistically signifi cant differences were observed in surface roughness among the groups (P 0.05). In conclusion; Biodentine seems a good alternative to MTA and other furcation perforation repair materials. However, further research is needed to warranty endodontic usage of Biodentine.

Abstract:
The Self-Adjusting File (SAF) represents a paradigm-shift in modern endodontics, as the first instrument that truly addresses the basic cleaning, shaping and irrigation principles of endodontic treatment in all three dimensions. The SAF is a hollow file designed as an elastically compressible, thin-walled pointed cylinder that is composed of a nickel titanium lattice. This motorized file is used as a single instrument to achieve complete 3D root canal cleaning and shaping in a minimally invasive way. Its hollow shape allows for the continuous flow of irrigant through its lumen to achieve superior disinfection. The SAF’s mode of operation eliminates many of the risks and drawbacks attributed to rotary NiTi files, leading to better and safer treatment. The SAF is supported by dozens of research papers published in the leading endodontic journals, representing its superiority over rotary fi les and turning it into a true evidence-based endodontic concept.

Abstract:
The Flow Jac System , constitutes an alternate highly innovative esthetics, for patients who don’t tolerate brackets and do not accept the use of removable appliances; it is ideal for simple alignments and resolution of relapse and constitutes a solution both in adults for the procedures of preprosthetics as well as in children and adolescents to maintain clean oral tissues and a healthy periodontics.Th e objective of the presentation of the system of mini tubes is to inform about this new and latest alternative to treatment, its components, installation, strategies and basic biological fundamentals and biomechanics. Th e system has been patented in Colombia and has proven successful in more than 300 patients for about 6 years now.For the movement, it is required millimeter tubes of about 2 to 5 millimeters which support arches that are super elastic activated through the dental pieces to move in the resolution of malocclusions. Th e clinical procedures in this system are a combination of science and art which require more dedication and analysis to obtain better results, both in simple procedures as in complex cases of class II, class III and deviation of jaws, likewise the bio chemistry involved in the closing of spaces depends on the application of differential forces which do not take into account wings of bracket.It is consider as an orthodontics system minimally invasive which give patients a high level of hygiene, comfort and esthetics, respecting the muscular function and the biological space between the soft tissue and bucal surface of the teeth. Its fundaments constitute the sum of basic concepts of the main techniques in orthodontics and its learning theory is based on the sum of knowledge and application of own strategies and other philosophies.

Abstract:
Molar incisor hypomineralization (MIH) is a common developmental condition resulting in enamel defects in first permanent molars and permanent incisors. It presents at eruption of these teeth. The aim of this study is to determine the possible causes which led to MIH in a group of school children living in Ankara, Turkey. For this purpose the study group consisted of 30 children who affected from MIH. The datas were recorded using the modifi ed DDE index. These children were matched by age with other children with apparently normal first molars (control group). Children and their parents were invited for a survey about their medical history. The datas were evaluated using SPSS 15.0 soft ware. The signifi cance level was set at 0.05. A statistically significant difference was determined between the groups in response to the question related to the disease while pregnant (P<0.05). Also the ratio of suffering from tonsillitis were higher in the study group than the control group (P<0.05). Th e number of the children affected by MIH is low in this study but the results of this study will provide guidance to clinicians and parents with other previous epidemiological reports.
