Multiple hyperodontia: report of a case with 17 supernumerary teeth with non syndromic association

Supernumerary teeth or hyperodontia is an infrequent developmental alteration that appears in any area of the dental arches and can affect any dental organ. Multiple hyperodontia can be associated with several syndromes such as Gardner’s, cleidocranial dysplasia, tricho-rhino phalangic syndrome or in patients with cleft lip and palate.However, it can be present in patients without any systemic pathology. The presence of supernumerary teeth is associated with different alterations in neighboring teeth, being the most common: over retained teeth or delayed eruption, ectopic eruption, dental malposition, occlusal problems, diastemas and rotated neighboring teeth, among a series of associated pathologies.The routine use of radiographic images during examination is a valuable tool that helps make the early diagnosis of these types of abnormalities. Keeping in mind that there are different treatment options, the therapeutic modalities increase. A case of a 20 year old female patient with multiple supernumerary teeth with non syndromic association is presented. The teeth were located in the maxilla and the mandible causing a severe malocclusion

Ergonomic factors that cause the presence of pain muscle in students of dentistry

Objective: To identify the ergonomic factors and the presence of muscular pain in dental students of VIII, IX, X semesters presently practicing at the clinics of the College of Dentistry of university of Cartagena, Colombia, South America. Materials and methods: This is a descriptive study carried out in dental students of the VIII, IX, and X semesters which were undergoing clinical practice at the College of Dentistry of University of Cartagena. A convenience sample of 83 students who met the inclusion criteria was taken and those who agreed to participate signed an informed consent. Data collection was obtained by means of a structured questionnaire for ergonomic factors and the presence of pain was identified palpating the muscles object of the study by a physical therapist. The variables evaluated were: presence of pain, affected muscles, affected zones, gender, postures and work environment. Results: The adoption of inadequate postures such as exaggerated flexions or cervical torsions could generate a higher frequency of muscular pain in dental students. The approximating muscle of the thumb showed 11% frequency of pain. The presence of muscular pain was higher for the female group participating in this study. Conclusions: Dentists are prone, since the beginning of their clinical practice as students, to lesions of the skeletal muscle system due to the clinical exercise of the profession, being the most common, muscle pain in the back, neck, shoulders and hands. This would imply initiating an occupational health program promoting healthy lifestyles in their academic environment and their future professional life, at the beginning of their clinical practice in dental school

Mineral trioxide aggregate in primary teeth pulpotomy. A systematic literature review

Evidence-based dentistry is a critical evaluation, awareness of the available evidence to improve decision making about the care of individual patients and / or communities. Objective: To systematically analyze the available scientific literature on clinical and radiographic results of two materials used in pulpotomy in primary teeth: formocresol and mineral trioxide aggregate. Materials and methods: It was identified relevant publications through a search of electronic databases such as MEDLINE (Ovid) and The Cochrane Library. To be included in the review, studies had to define the material used in child patients with pulp exposure by caries or tooth-alveolar trauma. Results: Of the 21 articles obtained in the initial phase of the review, only 19 were available in full text and of these only met the requirements for inclusion 6 items, which were confronted, analyzed and discussed later. Conclusions: The clinical evidence available showed significant differences regarding the use of a material or another. In addition to the findings of clinical follow - radiographic and taking into account the potential toxicity of formocresol suggest the use of mineral trioxide aggregate pulpotomy of primary teeth

Elements of the anthropological theory of didactics in the selection of contents in a course of fluid mechanics in engineering, a case study in Spanish universities.

The Anthropological Theory of Didactics has been applied to the field of didactics of mathematics with remarkable success. Fluid Mechanics is a discipline with a strong mathematical background, where mathematics is used for modeling the continuous nature. In addition, the Fluid Mechanics concepts are essential for the future engineer or scientist. For this reason, it is worth thinking whether the content that developed in engineering schools or science faculties are those demanded by the future professionals. The analysis has been done within the context of a case study framed in the Spanish noosphere, more particularly Universities and Companies. In this direction, the objective of this article is to know the institutional distance between the University and society as a demander of technologies based on Fluid Mechanics. To this end, the methodology based on the issuance of a questionnaire to experts focused on aspects such as present and emerging content associated with the Fluid Mechanics of an engineering degree is used. Note that the number of experts selected is reduced so as to consider the study as a sourcing for introducing expert thoughts on the fluid mechanics conception between university and companies. The results highlight the existence of an institutional distance between the University and the Enterprise (as a technology executor) in the conception of contents, thus establishing an area of potential improvement within the noosphere associated with fluid mechanics in Spain.post-print771 K

Agrandamiento gingival farmacoinducido: Serie de casos

Introduction: Gingival enlargement (GA) is a benign condition of the oral cavity that is characterized by the excessive growth of the gingiva in mass and volume. This lesion is not only caused by hereditary factors or poor oral hygiene, but also by the intake of medications, including antihypertensive, anticonvulsant and immunosuppressive drugs. Objective: To sensitize the prevention or early care in patients with pathologies that merit the use of antihypertensive and anticonvulsants in conjunction with the dentist, to treat or avoid the drug-induced gingival enlargement (DIGE). Materials and methods: A series of clinical cases of patients with gingival enlargement by various drugs are reported, including Phenytoin, Amlodipine and Nifedipine. Periodontal and gingivectomy hygienic phase measures were applied to obtain better effects. Results: Satisfactory results were obtained with a considerable decrease in DIGE. Conclusions: The integral management is important in conjunction with the treating physician to follow up the drug that can be generating gingival enlargement. It is necessary to employ an initial approach with strategies of periodontal hygiene, and in severe cases and, as last resort, the periodontal surgery with gingivectomy and gingivoplasty

ATOMISTIC SIMULATIONS OF HYDROGEN EMBRITTLEMENT IN PALLADIUM

Palladium hydrogen system has unique catalytic activities and up to 1:1 hydrogen adsorption capability. It is studied in the context of hydrogen embrittlement, which is a subset of stress corrosion cracking, with classical molecular dynamics techniques. Hydrogen embrittlement is a long lasting metallurgical challenge due to its intractability and unpredictability. First, the thermomechanical properties are studied parametrically in a wide range of hydrogen concentration and temperature, serving a database for hierarchical multiscale simulations and constitutive models in mechanics. To quantitatively describe the kinetics of hydrogen segregation at crack tips, anisotropic diffusion properties are investigated under tensile/compressive loads in both elastic and plastic regions at different temperature and hydrogen concentration. Meanwhile, vacancy concentration as a function of strain is also studied in the same circumstances to quantitatively study the super abundant vacancy phenomenon and how it could initiate hydrogen embrittlement. Further, hydrogen interactions with coherent twin boundary is simulated at finite temperature. The local strength of twin boundary with hydrogen is estimated by molecular dynamics nanoindentation. At last, the heterogeneous nucleation mechanisms of defects under the influence of hydrogen content in single crystal pillars with different growth orientations are investigated to reveal the slip versus twin competition in plastic deformation. In short, a wide range of interesting topics are rigorously explored in the realm of atomistic hydrogen embrittlement

EEEs y desarrollo de competencias profesionales en la docencia en lengua inglesa en la EUEE de la Universidad de Sevilla: El caso de Cost Accounting

Desde los años 70, los organismos contables internacionales vienen cuestionando la forma tradicional de enseñar la Contabilidad y enfatizando la importancia de la adquisición de competencias, especialmente las profesionales. La adaptación del sistema universitario español al Espacio Europeo de Educación Superior (EEES) debería ser un revulsivo para adoptar los nuevos modelos de formación centrados en el trabajo y en el desarrollo de competencias del alumno. En este trabajo analizamos el impacto del empleo de estudios de caso y supuestos basados en plantillas de hojas de cálculo sobre el desarrollo de competencias profesionales —especialmente las de comunicación en inglés—, la adquisición de conocimientos y la motivación del alumno. Los resultados obtenidos ponen de manifiesto que esta estrategia docente ha sido muy positiva en todos los aspectos previamente mencionados

Residual cyst with semisolid content, a clinical case.

Objective: to present a clinical case of a residual cyst in the right maxillary region with semi- solid content. Main data of the case: 61-year-old patient who comes to consultation for the realization of up- per jaw dentures, during the clinical examination a slight facial asymmetry of the right side is observed; radiographic and tomographic examination revealed a radiolucent lesion in the right premolar region. It is diagnosed as a residual cyst and an enucleation is decided; during the surgical procedure a viscous content of yellowish coloration and semi-solid content is observed. Main comments: it is very rare to find residual cysts with semi-solid content, since they gene- rally have purulent or serosanguinous contents
