In both cases, the quality indicators, showed that the articles signed by dentists had values exceeding the mean of the category where published.Figures shows the output distribution by specialties for the three periods, with the output and impact indicators of the DOSM and Non-DOSM categories. General Dentistry was the most productive area in the three periods in DOSM and Non-DOSM, save the first period of Non-DOSM, when the top specialty was Public Health. General bibliometric indicators of the database. Dentistry, Oral Surgery, and Medicine, DOSM; other JCR categories,Non-DOSM. “% Dentistry”is the relative dental production, DOSM +Non-DOSM in Web of Science, representing the percentage of the total production of dentistry with the rest of the sciences. b Geographic analysis of the scientific output in Dentistry: relative data (%DOC).Top-20-ranking countries in terms of production with respect to the total of each period studied. The countries are arranged according to their absolute total production in the three periods analysed. Production variation in the three quarters studied can be seen graphically in “Trend”Clin Oral Invest
percentage columns represent those that provide c. 70 % of the output in each period Clin Oral Invest shows the relations between the specialties (SNAdiagram) in the three periods. The six diagrams indicate the interconnection between areas, in DOSM and Non-DOSM. Discussion To date, partial analyses of dental-research activity has been published, works in which the output is analysed in a Dentistry specialty or theme , in a journal or set of them or rather broad geographical analyses . In many such works, MEDLINE has been used to analyse dental-research output but, in general, the WoS is preferred over other databases because it is multidisciplinary (covering all scientific and technological fields), their well-documented quality is guaranteed by peer review [20], andit track citations to calculate an impact factor reflecting use by journals in the . However, in these cases,the analysis of production has always been limited to those published in the DOSM category, and, as observed by Gil et al. , “some dental research papers included in other categories of the ISI database may have been missed”. The most productive JCR Non-DOSM categories in the three periods studied with their indicators of output and impact. Dental production by specialties in each period analysed, in DOSM and Non-DOSM, with their indicators of output and impact (see Table 1).(1)General Dentistry, (2) Dental Materials, (3) Orthodontics and Dentofacial Orthopedics, (4)Oral and Maxillofacial Pathology, (5) Pediatric Dentistry, (6)Dental Public Health, (7) Oral and Maxillofacial Radiology,(8) Oral and Maxillofacial Surgery Clin Oral Invest.
