Programa de atención buco-dental en alumnos discapacitados psíquicos con epilepsia.

El proyecto pretende cubrir las necesidades de atención sanitaria en salud buco-dental y desarrollar hábitos y costumbres sanas de higiene buco-dental en los alumnos. El objetivo es que los discapacitados psíquicos alarguen sus períodos de bienestar y disminuyan las enfermedades buco-dentales, que aparecen por el tipo de vida, la conducta y los efectos de la medicación en los alumnos con epilepsia. Otros objetivos son reconocer y apreciar el propio cuerpo y contribuir a su desarrollo; reconocer principales patologías buco-dentales; establecer medidas preventivas para impedir enfermedades; y realizar estrategias ante un problema de salud individual y los pasos del protocolo de actuación de higiene buco-dental. En cuanto a la metodología, una vez diseñadas las programaciones, se elabora el material para mejorar la práctica y adaptarlo a las necesidades de los alumnos, de forma normalizada, integradora y atendiendo a la diversidad. Las actividades se realizan en las aulas, después en la consulta de odontología y finalmente en los departamentos de Terapia Ocupacional y Centro de Día, manteniendo así una estrecha colaboración entre auxiliares, terapeuta ocupacional, educadores y maestros. La evaluación es continua y se realiza a través de registros de observación individual, cuestionarios para las familias, datos clínicos, consulta odontológica y materiales. Se elaboran fichas de actividades; registros de evaluación; cuestionarios como el de datos demográficos, datos clínicos, y hábitos de alimentación sana; guías informativas sobre las actividades buco-dentales, fichero de consulta para enfermedades, alimentación sana y hábitos de higiene oral; vídeos formativos; pictogramas de exploración dental; guías fotográficas; y protocolo de actuación. Se incluye el cuestionario de exploración buco-dental y los resultados, el cuestionario para las familias, el programa guía para alumnos y profesionales de atención buco-dental, y la guía para alumnos y profesionales de anatomía buco-dental..

Actitud de los escolares murcianos hacia la salud dental

Construir y validar una escala para medir la actitud de los escolares murcianos hacia la salud dental, conocer sus actitudes e identificar algunas de las variables que influyen en dicha actitud.Se hizo un muestreo aleatorio, por tipo de estudios y situaci??n del centro, y por aulas, siendo el tama??o de la muestra de 4221 alumnos. Se construyo una escala de Likert de cinco opciones para conocer la aptitud de los escolares murcianos hacia la salud dental.Como resultado final, el 6,8 por ciento de los escolares no cepilla nunca o casi nunca, mientras que el 65 por ciento lo hace una vez al d??a por lo menos. El 16,2 por ciento de la poblaci??n escolar nunca ha visitado al dentista y el 13,9 por ciento presenta ansiedad dental. La actitud media ha sido de 3,91 sobre 5, que puede considerarse regular-buena. Los escolares de EGB presentan la mejor actitud, independientemente de sus h??bitos higi??nicos dentales. En definitiva, la variable que m??s influye en la actitud es la ansiedad dental, quedando en un segundo plano la frecuencia del cepillado, la periodicidad de las visitas dentales y el sexo (las mujeres presentan mejor actitud que los hombres). Los aspectos de la salud dental mas necesitados de cambios positivos son el miedo y la preocupaci??n por la salud dental.

Multidisciplinary analysis of clinical cases: a transition towards active learning in dental education

In the past 2009/10 academic year, we took steps towards introduction of active methodologies, from a multidisciplinar approach, into a conventional lecture-based Dental Education program. We consolidated these practices in the current 2010/11 year, already within a new Bologna-adapted scheme. Transition involved (i) critical assessment of the limitations of traditional teaching (ii) identification of specific learning topics allowing for integration of contents, (iii) implementation of student-centred learning activities in old curricular plans (iv) assessment of students' satisfaction and perceived learning outcomes, (v) implementation of these changes in new Bologna-adapted curricula

Analysis of chemical bonding and aromaticity from electronic delocalization descriptors

Interactions between electrons determine the structure and properties of matter from molecules to solids. Therefore, the understanding of the electronic structure of molecules will enable us to extract relevant chemical information. In the first part of this thesis, we focus our attention on the analysis of chemical bonding by means of the Electron Localization Function (ELF) and the Domain-Averaged Fermi Hole analysis (DAFH). In the second part, we assess the performance of some indicators of aromaticity by analyzing their advantages and drawbacks. We propose a series of tests based on well-known aromaticity trends that can be applied to evaluate the aromaticity of current and future indicators of aromaticity in both organic and inorganic species. Moreover, we investigate the nature of electron delocalization in both aromatic and antiaromatic systems in the light of Hückel’s (4n + 2) rule. Finally, we analyze the phenomenon of multiple aromaticity in all-metal clusters.

The intelligibility of cleft palate speech with and without dental prosthesis

This paper discusses a study to investigate the possibility of quantifying and analyzing the speech of cleft palate subjects.

Are there hazardous auditory effects of high-frequency turbines and ultrasonic dental scalers on dental professionals?

The purpose of this pilot study was to survey dentists in the St. Louis area to assess their subjective opinion of commonly used dental handpieces as well as history of noise exposure and use of hearing protection. Selected handpieces were then chosen to measure their output levels and determine if emissions are hazardous to the auditory system.

Dental training system using haptic technology

In the U.K., dental students require to perform training and practice on real human tissues at the very early stage of their courses. Currently, the human tissues, such as decayed teeth, are mounted in a human head like physical model. The problems with these models in teaching are; (1) every student operates on tooth, which are always unique; (2) the process cannot be recorded for examination purposes and (3) same training are not repeatable. The aim of the PHATOM Project is to develop a dental training system using Haptic technology. This paper documents the project background, specification, research and development of the first prototype system. It also discusses the research in the visual display, haptic devices and haptic rendering. This includes stereo vision, motion parallax, volumetric modelling, surface remapping algorithms as well as analysis design of the system. A new volumetric to surface model transformation algorithm is also introduced. This paper includes the future work on the system development and research.

A healable supramolecular polymer blend based on aromatic π-π stacking and hydrogen bonding interactions

An elastomeric, supramolecular healable polymer blend, comprising a chain-folding polyimide and a telechelic polyurethane with pyrenyl endgroups, is compatibilised by aromatic π−π stacking between the π-electron-deficient diimide groups and the π-electron-rich pyrenyl units. This inter-polymer interaction is key to forming a tough, healable, elastomeric material. Variable temperature FTIR analysis of the bulk material also conclusively demonstrates the presence of hydrogen bonding, which complements the π–π stacking interactions. Variable temperature SAXS analysis shows that the healable polymeric blend has a nanophase-separated morphology, and that the X-ray contrast between the two types of domain increases with increasing temperature, a feature that is repeatable over several heating and cooling cycles. A fractured sample of this material reproducibly regains more than 95% of the tensile modulus, 91% of the elongation to break, and 77% of the modulus of toughness of the pristine material.

Anion-pi, Lone-Pair-pi, pi-pi and Hydrogen-Bonding Interactions in a Cu-II Complex of 2-Picolinate and Protonated 4,4 '-Bipyridine: Crystal Structure and Theoretical Studies

A Cu-II complex of protonated 4,4'-bipyridine (Hbyp) and 2-picolinate (pic), [Cu-2(pic)(3)(Hbyp)(H2O)(ClO4)(2)], has been synthesised and characterised by single-crystal X-ray analysis. The structure consists of two copper atoms that have different environments, bridged by a carboxylate group. The equatorial plane is formed by the two bidentate picolinate groups in one Cu-II, and one picolinate, one monodentate 4,4'-bipyridyl ligand and a water molecule in the other. Each copper atom is also weakly bonded to a perchlorate anion in an axial position. One of the coordinated perchlorate groups displays anion-pi interaction with the coordinated pyridine ring. The noncoordinated carboxylate oxygen is involved in lone-pair (l.p.)-pi interaction with the protonated pyridine ring. In addition there are pi-pi and H-bonding interactions in the structure. Bader's theory of "atoms in molecules" (AIM) is used to characterise the anion-pi and l.p.-pi interactions observed in the solid state. A high-level ab initio study (RI-MP2/aug-cc-pVTZ level of theory) has been performed to analyse the anion-pi binding affinity of the pyridine ring when it is coordinated to a transition metal and also when the other pyridine ring of the 4,4'-bipyridine moiety is protonated. Theoretical investigations support the experimental findings of an intricate network of intermolecular interactions, which is characterised in the studied complex, and also indicate that protonation as well as coordination to the transition metal have important roles in influencing the pi-binding properties of the aromatic ring.

Effect of H-bonding on the ambivalence of SCN- towards copper(II)

Condensations of 2-(2-aminoethyl)pyridine with 4-methylimidazole-5-carboxaldehyde and 1-methyl-2-imidazolecarboxaldehyde generate the tridentate N donor ligands L and L' respectively. Reactions of Cu(NCS)(2) with L and L' yield respectively CuL(SCN)(NCS) (1) containing a CuN4S core and CuL'(NCS)(2) (2) having a CuN5 core. Both the cores are square pyramidal with SCN bound in 1 at the axial position through the S end. This differential behaviour of SCN in the two complexes despite the ligands being very similar, is investigated by DFT calculations at the B3LYP/TZV level. It is found that DFT calculations predict isolation of the Cu(ligand)(NCS)(2) species for both the ligands L and L'. Presence of an offsetting intermolecular H-bonding between the N atom of the thiocyanate and the N-H proton of the ligand L of an adjacent molecule makes the binding of SCN via the S end feasible in 1 resulting in the H-bonded-dimer Cu2L2(SCN)(2)(NCS)(2). The strength of the H-bond is estimated as 27.1 kJ mol (1) from the DFT calculations. The question of such H-bonding does not arise with L' as it lacks in a similar H atom. Dimeric 1 represents a case of two non-interacting spins. (C) 2008 Elsevier B. V. All rights reserved.
