Introduction: Until now, there are no reports of quantity and quality of publications in oral and maxillofacial surgery (OMFS) conducted in Chile, which is why the aim of this study is to determine the productivity and methodological quality (MQ) of OMFS clinical articles in Chile in the period 2001-2012. Material and Methods: Bibliometric study. A systematic search in MEDLINE, Science Citation Index Expanded (Web of Science-ISI) and SciELO was conducted. Only clinical items related to OMFS made by Chilean authors were selected. Journal name, publication year, primary Chilean institution affiliated and specialty area were registered. Those articles related to surgical therapy were evaluated according to Sackett's level of evidence and MINCIR-therapy scale for MQ. Results are presented using descriptive statistics. Results: 68 articles were selected. Growth was observed in the number of publications, from 3 (4.4%) in 2002 to 8 (11.7%) in 2012, showing a peak (13 articles) in 2009. The most productive institution was Universidad de Chile (n = 20). Majority of items are cases of surgical pathology. 91.2% of the articles observed had a type 4 level of evidence. The MQ average of analyzed articles was 9.9 ± 4.0 points, verifying only 4 items of good MQ (18 or more points). Conclusion: OMFS scientific production in Chile has increased during the last decade. However, the amount of articles of good level of evidence is low and MQ is poor. [ABSTRACT FROM AUTHOR]

In January 2007, the Chilean Journal of Agricultural Research was indexed by the Institute of Scientific Information (ISI). This paper reviews the research that has been published since 2007 by using records extracted from the Web of Science database. The papers published were mostly affiliated to researchers from Chile, and six out of the ten most-contributing countries were from Latin America. The analysis by institutions showed Universidad de Concepcion as the most prolific, although this result is not valid. A lack of standardization in the manner the Instituto de Investigaciones Agropecuarias (INIA) subscribed its address on each paper caused a disaggregation of the information. This was proven by the manual duration of each record that was affiliated to any of the centers belonging to INIA. The journal has a serf-citation rate of 19.3%, value that is relatively high if compared to other journals from the same subject category listed on The Journal Citation Reports 2010. Finally, this work should be considered a bibliometric snapshot of the current situation of the journal that will serve as a benchmark when new evaluations are made in a few-years time.

The Hirsch's h-index is a new bibliometric indicator that has been considered useful to evaluate the scientific productivity of individual researchers and scientific journals. This paper uses it to evaluate the productivity of the 15 research universities of Chile. Since in Chile public rankings of perception of their universities are beginning to be common, the article relates the h-index with a pair of rankings based on the prestige that the potential employers and students of the last level of secondary education have of them. I found that both rankings of perception were related and the same happened when they were associated to the h-index of Hirsch. The association was greater for the ranking based on the perception by potential students at those universities. [ABSTRACT FROM AUTHOR]
