ABSTRACT
Los traumatismos dentoalveolares son lesiones que afectan a los dientes y los tejidos de sostén, incluyendo desde la pérdida de la integridad del diente hasta el desplazamiento total o parcial de su posición anatómica. Actualmente constituyen la segunda causa de atención odontopediátrica después de la caries. La búsqueda de información se realizó en la base de datos de PubMed de INFOMED y EBSCO; se utilizó dental trauma como descriptor. También se revisaron revistas médicas nacionales e internacionales en INFOMED, así como libros de texto. Se describieron los aspectos esenciales y actuales de los traumatismos en cuanto a prevalencia e incidencia, clasificación, etiología, factores predisponentes, localización, tipo de lesión, pronóstico y alteraciones de los dientes en desarrollo.
Dental and alveolar traumas are lesions that affects teeth and supporting tissue they may range from the loss of the whole integrity of the tooth to the total or partial displacement of its anatomical position. Nowadays they are the second cause of dentist pediatric care after cavities. The searching for information was carried out in PubMed and INFOMED and EBSCO using the descriptor dental trauma. In International and national medical journals were also reviewed as well as books. The current and essential aspects of traumas were described taking into account prevalence, incidence, classification, etiology, predisposing factors, site, kind of lesion, prognosis and teeth alteration.

Proton structure effects in hydrogenic bound states are analyzed using nonrelativistic QED effective field theory. Implications for the Lamb shift in muonic hydrogen are discussed. Model-dependent assumptions in previous analyses are isolated, and sensitivity to poorly constrained hadronic structure in the two-photon exchange contribution is identified.
ABSTRACT
We show that in the standard model the parametrically leading (by a factor 1/α(s)) contribution to the inclusive CP asymmetry in BâX(s,d)γ decays arises from a long-distance effect in the interference of the electromagnetic dipole amplitude with the amplitude for an up-quark penguin transition accompanied by soft gluon emission. Using model estimates for the associated hadronic parameter Λ(17)(u), we predict a value in the range -0.6% < A(X(s)γ)(SM) < 2.8%. In view of current experimental data, a future precision measurement of the flavor-averaged CP asymmetry would signal the presence of new physics only if a value below -2% was found. A cleaner probe of new physics is offered by the difference of the CP asymmetries in charged versus neutral BâX(s,d)γ decays.
ABSTRACT
We consider a class of models in which supersymmetry breaking is communicated dominantly via a U1' gauge interaction, which also helps solve the mu problem. Such models can emerge naturally in top-down constructions and are a version of split supersymmetry. The spectrum contains heavy sfermions, Higgsinos, exotics, and Z' approximately 10-100 TeV, light gauginos approximately 100-1000 GeV, a light Higgs boson approximately 140 GeV, and a light singlino. A specific set of U1' charges and exotics is analyzed, and we present five benchmark models. The implications for the gluino lifetime, cold dark matter, and the gravitino and neutrino masses are discussed.
ABSTRACT
A new method for a precision measurement of the Cabibbo-Kobayashi-Maskawa matrix element |V(ub)| is discussed, which combines good theoretical control with high efficiency and a powerful discrimination against charm background. The resulting combined theoretical uncertainty on |V(ub)| is estimated to be 10%.
