Résumé
Los traumatismos dentoalveolares que afectan a escolares pueden involucrar a los tejidos blandos y/o duros de las piezas primarias y permanentes jóvenes. Las causas por las que se producen son múltiples e incluyen caídas, accidentes en el hogar, actividad deportiva en el colegio o el club, accidentes de tránsito. El objetivo de este trabajo es presentar la resolución y el seguimiento a dos años de dos situaciones clínicas de traumatismos dentoalveolares en pacientes escolares que concurrieron a la Universidad de Buenos Aires, Facultad de Odontología, Odontología Integral Niños (AU)
Dentoalveolar trauma in schoolchildren can involve soft and/or hard tissues of deciduous and young permanent teeth. It has multiple causes, including falls, home accidents, sports accidents at school or at a club, and car accidents. The aim of the present work was to show treatmentand two-year clinical follow up of dentoalveolar trauma in schoolchildren seen at the Universidad de Buenos Aires, Facultad de Odontología, Odontología Integral Niños (AU)

We studied chromosomal abnormalities in arrested embryos produced by assisted reproductive technology with fluorescence in situ hybridization (FISH) and comparative genomic hybridization (CGH) in order to determine the best technique for evaluating chromosomal aneusomies to be implemented in different situations. We examined individual blastomeres from arrested embryos by FISH and arrested whole embryos by CGH. All of the 10 FISH-analyzed embryos gave results, while only 7 of the 30 embryos analyzed by CGH were usable. Fifteen of the 17 embryos were chromosomally abnormal. CGH provided more accurate data for arrested embryos; however, FISH is the technique of choice for screening in preimplantation genetic diagnosis, because the results can be obtained within a day, while the embryos are still in culture.
