Background
Due to the lack of bibliometric studies in the field of lingual orthodontics in dentistry, the aim of this study was to assess the evolution and current status of activity in this field during the period 1978–2017.
Methods
A bibliometric analysis of the scientific articles indexed in the Science Citation Index-Expanded of the Web of Science and in the Scopus® database was performed using the truncated terms “ling* apppli*” or “ling* orthod*” or “ling* bracket*”. The types of texts included for analysis were limited to “articles” and “reviews”. The following information was extracted from each article identified: title, authors’ name(s), institutional affiliation(s), country of origin, journal title, year of publication, type of publication, and number of citations.
Results
A total of 341 articles were identified by 646 different authors, 6.2% were reviews and 93.8% were other types of journal articles. Bibliometric indicators showed a tremendous increase in the rate of publication over time with two peaks in productivity in 1989 and 2013. Fourteen authors and 15 institutional collaboration networks were identified in which European institutions were the most productive. Methodological articles were the most frequent types of research articles (28.1%), followed by case reports/series (17.1%), and narrative reviews (4.7%). Articles providing the highest quality evidence were interventional clinical trials (1.8%) and systematic reviews (0.9%). The remaining articles were non-research papers and were for information purposes only.
Conclusions
Bibliometric indicators point to an irregular increase in the numbers of published works in lingual orthodontics over time. Research output is dominated by methodological articles as a technique-driven subspecialty. Although articles on lingual orthodontics are published mainly in North American journals, lingual orthodontics is largely a European domain.
