The total of 3,818 publications collected from the Web of Science database had their collected data measured using scientometric techniques. The search strategy TS=topic for black holes research was refined to 15 years, from 2008 to 2022, and only selected Indian research productivity. The collected data was measured from various angles and types of documents, with 97.590% articles and the highest annual growth rate of 23.664% in 2018. The most prolific author, Ajith Parameshwaran, from the Bangalore International Center for theoretical science, published 119 papers with 32,405 citations (61 h-index). The Journal of Physical Review is the most prolific, with 604 publications and 16,068 citations. The most frequent keyword occurrences are "black holes," with 435 reflected. The Department of Science and Technology in New Delhi is the most prolific, having published 664 papers with a total of 14,346 citations (58 h-index). The black research involved 80 countries, out of which India secured the 8th place in the world's contribution. The prepared research area related to black holes, namely the astronomy and astrophysics research area, is 2,423 with 47.45% of publications. [ABSTRACT FROM AUTHOR]

Regenerative endodontics (RE) is a dynamic field with widespread global impact. The aim of this bibliometric analysis is to highlight India's contribution in the field. Electronic search was performed in PubMed and Web of Science database till December 2019 using the search terms "Dental pulp regeneration," "Pulp revascularisation," "Revitalisation," "Regenerative endodontic," and their permutation. Articles of Indian authors with affiliation to Indian institutes were included. The following data were extracted: first author, institute and state of affiliation, year and journal of publication, study design, level of evidence (LOE), and number of citations. A total of 76 articles (case reports [n = 29, 38.15%], review [n = 25, 32.8%]) were published between 2008 and 2019. Majority (42.6%) were categorized as LOE 4. 7.4% articles were in LOE1 category. Eight percent articles had citations above 100 (highest cited-354 citations). The average yearly growth rate between 2011 and 2019 was 33.28% and highest number of publications was in the year 2015. The south zone had the maximum publications. At an institutional level, Centre for Dental Education and Research, All India Institute of Medical Sciences, New Delhi, had the maximum publications. Journal of Conservative Dentistry published the highest number of articles. India contributed 7.6% of the global PubMed indexed publications and reported 22% of clinical trials. This analysis reveals increasing trend of research in RE in India. However, it highlights the need to generate articles with higher LOE by conducting quality multicenter trials and promote national and international collaborations. [ABSTRACT FROM AUTHOR]
