General terms such as tooth or enamel were deleted because they introduced excessive noise and because if the article concerned Dentistry, it could always be recalled by other more specific terms. Citation average Relativize the number of citations (NCit) with of citable documents through a division by what gives the average of citations reached by the documents CAVG 0NCit/N citable doc JCR journal citation reports, IF impact factor Clin Oral Invest terms, many shared a common root, and therefore were submitted to a process of lemmatization. This gave rise to a final list of 77 basic descriptors; these truncated terms being assigned to one or more dental specialties. In this way, when one of these terms appears in the title, keywords or a summary of an article, this record is labelled with the specialty or specialties previously associated with this term (i.e. record in the title, key words, or abstract of which appear the term periapic* is labelled with the specialties Periodontics and Endodontics). Thus, when an article covers various themes at a time, using several of the truncated terms associated with several specialities, it is labelled simultaneously with these different specialties, offering us therefore information on how to relate these different disciplines within Dentistry.Finally, the Social Networks Analysis (SNA) provides a graphic view of the relations between different pairs of specialties. In the network, the specialties are rep-resented by nodes, and the number of documents that they share, by lines. To establish the strengths between the disciplines in each of the periods analysed, the total relations between pairs was calculated, representing in the network only those relations between pairs that jointly accumulated 75 % of the relations.
