Bioengineering of Dental Tissues: Bibliometric Analysis 2000-2011.
Abstract
Abstract: Introduction: There has been a noticeable increase in experimental use and therapies based on stem cells over recent years. Nevertheless, there is a lack of information about this progress in the dental field, which makes it difficult to trace development and design policies. The purpose of this study, as a first approach to the subject, is to determine a bibliometric profile for the investigation related to bioengineering of dental tissue at a worldwide scale, based on the MEDLINE database, for the period 2000-2011.Methodology: A bibliometric study was carried out. Every article indexed in the MEDLINE database and associated with the terms “stem cells” and “tooth regeneration” for the period 2000-2011 was included. The analyzed variables were publishing date, country of origin, language and publication type (original or review), journal, author, associated university and tissue source (human or animal). Results: For the entire period included in the study, 257 articles were found. Of these, 149 corresponded to original works published in English; 5 in other languages; 92 comprised literature reviews in English, 9 in other languages and 2 publications were included in the “others” category. The countries with the highest research productivity were the United States (24.51%), Japan (20.62%) and China (17.90%), while Brazil (3.9%) was the only Latin-American country found in the list. Animal tissues were used in 59.09% of them. The most productive authors were Ueda M (17) and Jin Y (11), whereas Fourth Military University (13), University of Tokyo (12) and Capital Medical University (10) had the largest number of publications.Conclusion: The United States, Japan and China concentrate about two thirds of the production. Latin-America was represented only by Brazil.

Bioingeniería de tejidos dentales: Análisis bibliométrico 2000-2011.
Resumen: Introducción: El creciente uso experimental de células madres y el perfeccionamiento de las terapias con estas es un hecho notorio en los últimos años. Sin embargo, en odontología no existen datos del desarrollo de esta área, lo que hace difícil un seguimiento o diseño de políticas. El objetivo de este estudio, siendo una primera aproximación a la temática, es definir el perfil bibliometrico de la investigación asociada a la bioingeniería de tejidos dentales a nivel mundial en la base de datos MEDLINE para el periodo 2000-2011. Metodología: Estudio bibliométrico. Se incluyeron todos los artículos asociados a los términos “stem cells” y “tooth regeneration” para el periodo 2000-2011, indexadas en MEDLINE. Se analizaron las variables: año de publicación, país de origen, idioma y tipo de publicación (original o revisión), revista, autor, universidad de afiliación y origen del tejido utilizado (humano o animal). Resultados: Para todo el período en estudio se hallaron 257 artículos: 149 trabajos de originales publicados en inglés, 5 en otros idiomas; 92 revisiones de literatura en inglés y 9 en otros idiomas; y 2 publicaciones en categoría otros. Los países más productivos fueron Estados Unidos (24,51%), Japón (20,62%), China (17,90%), el único latinoamericano es Brasil (3,9%). El 59,09% utilizó tejidos de origen animal. Los autores más productivos fueron Ueda M (17) y Jin Y (11), en universidades fueron Fourth Military University (13), University of Tokyo (12) y Capital Medical University (10). Conclusión: Estados Unidos, Japón y China concentran dos tercios de la producción, Brasil es el único representante latinoamericano. Palabras clave: Células madre, regeneración dental, bibliometría.
