Research collaboration is an essential component of research. Researchers, as well as the policy makers, are showing increasing interest in research collaboration. Forensic Science being multidisciplinary subject collaboration is essential. This study is an attempt to quantify and visualize the research collaboration in Indian Forensic Science and also to assess the impact of research collaboration. A total of 2096 bibliographic records pertaining to Indian Forensic Science literatures published during the period 1975-2012 are retrieved from the Scopus database. These data are analyzed and visualized using MS-Excel spreadsheets, VOSviewer, and Pajek software. It is found that the International Multilateral Collaborations are associated with greater citation impact. The study also reveals that the International Cooperation Index of India in Forensic Science research is 7.68. India has the highest Affinity Index value of 34.16 in Forensic Science with the USA. A new measure of international collaboration known as Authorship AFI is also proposed based on the number of collaborating authors.

A bibliometric analysis of the growth, authorship and publication patterns of forensic science literature for the period 2001 to 2013 was done using the data obtained from PubMed. MS-Excel worksheet was used for data analysis. The study revealed the exponential growth of forensic science literature. The relative growth rate fell from 0.83 in the year 2002 to 0.17 in the year 2013. The mean collaborative Index was 3.5; mean degree of collaboration was 0.89; mean collaborative coefficient was 0.6119 and mean modified collaborative coefficient was 0.6121 during the period of study. Forty one authors have contributed more than one percent of the total publication. Ten journals have contributed more than one percent of the total papers. Among these 'Journal of Forensic&Legal Medicine' ranks first with 16.10% papers. Cluster map of co-words was also created using VOSviewer.

Science and technology are continuously changing as new discoveries and inventions are made. Research funding agencies, project directors, and individual researches need to keep a tab on these dynamics. This chapter tracks the research directions of forensic science for a period of thirty-eight years starting from 1975. Data for the analysis was obtained from SCOPUS bibliographic and citation database. Over the study period there was an exponential growth of forensic science literature and documentation. The United States of America contributed about one fourth of the research papers published while the most prolific author was Bruce Budowle (University of Texas). The majority of the contributors were from the non-governmental sector. The Journal of Forensic Sciences was the most productive journal during the study period in terms of number of published papers. It was also found that internationally collaborated papers attracted more citations.

The data for this study was retrieved from the WoS platform using the Boolean search string (TS=periodont* OR gingiv*) AND (Year=1989 to 2018). The total number of bibliographic records retrieved was 69952. This study found that the literature growth pattern at the global level to be linear. Journal of Dental Research is the most favored journal; Offenbacher is top contributing author and University of Washington is the top contributing institution. The study also emphasizes the importance of research collaboration among the Periodontists.
