A cross-sectional study was undertaken evaluating all articles published in JIPS from January 2005 to December 2025. Data were retrieved from the journal's official archives. The key variables assessed included annual publication volume, study design, thematic domains, citation metrics, geographic distribution of authorship, and journal impact indicators. Data were analyzed using descriptive statistics and temporal trend evaluation. A total of 1238 articles were published during the study period. Original articles accounted for the largest number of publications (54.4%), followed by case reports/series (22%) and review articles (15%). The early publication trends (2005-2015) were focused on research related to complete denture and fixed partial denture, whereas the recent research (2016-2025) showed a substantial inclination toward implantology, digital prosthodontics, and biomaterial innovations. International authorship contributions increased progressively over the study period, particularly from America, Asia, Africa, and some European countries, reflecting the journal's expanding global reach. Citation performance improved substantially following key indexations in PubMed, Scopus, and Web of Science. The journal demonstrated a steady growth in the impact metrics, including impact factor, SCImago Journal Rank, and quartile rankings.
