Dear Editor-in-Chief
In recent years, viral infections as risk factors for the onset of oral cancers have been well discussed by the international academic-scientific community. In Brazil, according to the National Cancer Institute, in 2016, 15490 new cases of oral cancer were estimated, counted as 11140 men and 4350 women (1).
Bibliometry as a data collection and analysis technique has been used as an argumentative source in the search for investment resources in researches (2–3). The ISI Web of Knowledge, Web of ScienceTM database was used in this study for its international academic recognition to be considered one of the most comprehensive journals covering several areas of scientific knowledge (4). Data collection from the ISI Web of Knowledge/Web of ScienceTM database was performed using descriptors: oral cancer, HIV and Aids and exported to the HistCiteTM bibliometric analysis software to organize information and facilitate analysis.
According to Table 1, the search resulted in 201 articles on oral cancer and HIV/AIDS in the English, German and French languages, published in 111 different journals indexed to the main database and written by 954 authors with links to 340 institutions located in 37 countries. For the achievement of these articles, 7021 references were used, with an average of approximately 35 references per article (Table 1).

As it is showed in the amount of publication per year (Fig. 1), the first published paper dates from the year 1989. Until 1995, the publication record is relatively low, reaching a maximum of 4 records. There is a considerable increase in the number of records starting in 2012, in relation to previous years, with 24 published papers. The year of 2015 stands out with 29 records..

The journals with the highest number of records are presented in Table 2. The “Oral Oncology” and “Journal of the American Dental Association” with 16 and 10 papers, respectively, are highlighted. The most prominent journal in relation to the number of publications is specialized in publications related to head and neck neoplasias. The second journal is specialized in publications focused on dentistry. Although it is the second in number of publications, it is the first one with greater impact, presenting a citation index by amount of publications of 48, 8.

The paper distribution by the countries of origin of the authors, with more records is presented in Table 3. Despite the majority characteristic of the United States, it is possible to observe a distribution of scientific production to other America’s countries, such as Peru, in addition to other continents: Europe, Australia and Asia.

The 16 articles with the greatest impact were published in the period 1995–2010. Of these, the study published in 2008 (5) in the journal Oral Oncology, is the most cited by the authors of the 201 articles in the sample. Among the 201 papers, the study published in 2008 (6) in the journal European Journal of Surgical Oncology was the most cited in the Web of Science Database during the period.
Thus, this study have shown the evolution of publications in 26 yr of building scientific knowledge about oral cancer risks of people living with HIV/AIDS and can contribute to the development of new researches to fill knowledge gaps and implement effective public policies all around the world.
