Conventional diagnostic tools, including clinical probing and radiographic evaluation, are limited in detecting early disease activity. MicroRNAs (miRNAs) have emerged as potential biomarkers due to their regulatory role in inflammation and bone metabolism.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This scoping review aimed to map the available evidence on miRNA expression profiles in peri\u2010implantitis, identify knowledge gaps, and highlight miRNAs with potential diagnostic and therapeutic relevance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The review was conducted in accordance with Arksey and O\u2019Malley\u2019s framework, Joanna Briggs Institute guidelines, and PRISMA Extension for Scoping Review (PRISMA\u2010ScR) standards. Electronic databases (PubMed, Embase, and Web of Science) were searched up to October 2025. Studies evaluating miRNA expression in peri\u2010implantitis using human or relevant experimental samples (peri\u2010implant crevicular fluid [PICF], saliva, gingival tissue, serum) were included. Data were extracted and synthesized narratively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Eleven studies published between 2017 and 2025 were included. Dysregulated miRNAs were consistently associated with inflammatory and osteolytic pathways, including NF\u2010\u03baB, MAPK, Wnt\/\u03b2\u2010catenin, and RANKL signaling. Downregulation of miR\u201021\u20103p, miR\u2010150\u20105p, and miR\u20104484, and upregulation of miR\u2010155 and miR\u2010146a were frequently reported in peri\u2010implantitis. Polymorphisms such as miR\u2010155 rs767649 and miR\u201027a\u20103p rs895819 were linked to disease susceptibility. However, heterogeneity in study design, small sample sizes, and lack of longitudinal validation were common limitations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The mapped literature indicates that miRNA expression is altered in peri\u2010implant disease across several biological compartments, but the evidence remains heterogeneous and largely exploratory. Specific miRNAs should be regarded as candidate biomarkers requiring independent and prospective validation rather than established diagnostic tools. Standardized sampling and analytical methods, clearly defined disease criteria, adequately powered longitudinal cohorts, and external validation are needed before clinical translation can be assessed.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/ijod\/7830337","type":"journal-article","created":{"date-parts":[[2026,10,21]],"date-time":"2026-10-21T12:53:02Z","timestamp":1792587182000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mapping the Expression Profile of MicroRNA in Peri\u2010Implantitis: A Scoping Review"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7160-0404","authenticated-orcid":false,"given":"Madhumitha","family":"Muruganandam","sequence":"first","affiliation":[{"name":"Department of Periodontology Manipal College of Dental Sciences Mangalore Manipal Academy of Higher Education  Manipal India  manipal.edu"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5980-2698","authenticated-orcid":false,"given":"Sangeeta U.","family":"Nayak","sequence":"additional","affiliation":[{"name":"Department of Periodontology Manipal College of Dental Sciences Mangalore Manipal Academy of Higher Education  Manipal India  manipal.edu"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6943-5761","authenticated-orcid":false,"given":"Ashita S.","family":"Uppoor","sequence":"additional","affiliation":[{"name":"Department of Periodontology Manipal College of Dental Sciences Mangalore Manipal Academy of Higher Education  Manipal India  manipal.edu"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3080-512X","authenticated-orcid":false,"given":"Arpit","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Periodontology Manipal College of Dental Sciences Mangalore Manipal Academy of Higher Education  Manipal India  manipal.edu"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5393-5251","authenticated-orcid":false,"given":"Santhosh","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Periodontology Manipal College of Dental Sciences Manipal Academy of Higher Education  Manipal India  manipal.edu"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,21]]},"reference":[{"key":"e_1_2_14_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41415-024-7402-z"},{"key":"e_1_2_14_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/JPER.17-0739"},{"key":"e_1_2_14_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/jop.13612"},{"key":"e_1_2_14_4_2","doi-asserted-by":"publisher","DOI":"10.3390\/ijms21114147"},{"key":"e_1_2_14_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41368-018-0025-y"},{"key":"e_1_2_14_6_2","doi-asserted-by":"publisher","DOI":"10.3390\/ijms22115456"},{"key":"e_1_2_14_7_2","doi-asserted-by":"publisher","DOI":"10.1080\/1364557032000119616"},{"key":"e_1_2_14_8_2","doi-asserted-by":"publisher","DOI":"10.1097\/XEB.0000000000000050"},{"key":"e_1_2_14_9_2","doi-asserted-by":"crossref","first-page":"467","DOI":"10.7326\/M18-0850","article-title":"PRISMA Extension for Scoping Reviews (PRISMA-ScR): Checklist and Explanation","volume":"169","author":"Tricco A.
