The ultimate goal of periodontal therapy is to achieve the regeneration of all of the periodontal tissues. Thus, tissue engineering approaches have been evolving from simple membranes or grafts to more complex constructs. Hydrogels are highly hydrophilic polymeric networks with the ability to simulate the natural microenvironment of cells. In particular, hydrogels offer several advantages when compared to other forms of scaffolds, such as tissue mimicry and sustained drug delivery. Moreover, hydrogels can maintain a moist environment similar to the oral cavity. Hydrogels allow for precise placement and retention of regenerative materials at the defect site, minimizing the potential for off-target effects and ensuring that the treatment is focused on the specific defect site. As a mechanism of action, the sustained release of drugs presented by hydrogels allows for control of the disease by reducing the inflammation and attracting host cells to the defect site. Several therapeutic agents, such as antibiotics, anti-inflammatory and osteogenic drugs, have been loaded into hydrogels, presenting effective benefits in periodontal health and allowing for sustained drug release. This review discusses the causes and consequences of periodontal disease, as well as the advantages and limitations of current treatments applied in clinics. The main components of hydrogels for periodontal regeneration are discussed focusing on their different characteristics, outcomes, and strategies for drug delivery. Novel methods for the fabrication of hydrogels are highlighted, and clinical studies regarding the periodontal applications of hydrogels are reviewed. Finally, limitations in current research are discussed, and potential future directions are proposed.<\/jats:p>","DOI":"10.3390\/jfb14110545","type":"journal-article","created":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T02:46:47Z","timestamp":1699843607000},"page":"545","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["New Insights in Hydrogels for Periodontal Regeneration"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3862-4794","authenticated-orcid":false,"given":"Mafalda S.","family":"Santos","sequence":"first","affiliation":[{"name":"Department of Bioengineering, iBB\u2014Institute for Bioengineering and Biosciences, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisboa, Portugal"},{"name":"Associate Laboratory i4HB\u2014Institute for Health and Bioeconomy at Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandra B.","family":"dos Santos","sequence":"additional","affiliation":[{"name":"Department of Bioengineering, iBB\u2014Institute for Bioengineering and Biosciences, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisboa, Portugal"},{"name":"Associate Laboratory i4HB\u2014Institute for Health and Bioeconomy at Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1026-1995","authenticated-orcid":false,"given":"Marta S.","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Department of Bioengineering, iBB\u2014Institute for Bioengineering and Biosciences, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisboa, Portugal"},{"name":"Associate Laboratory i4HB\u2014Institute for Health and Bioeconomy at Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1809","DOI":"10.1016\/S0140-6736(05)67728-8","article-title":"Periodontal diseases","volume":"366","author":"Pihlstrom","year":"2005","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"392","DOI":"10.1002\/sctm.18-0181","article-title":"Concise Review: Periodontal Tissue Regeneration Using Stem Cells: Strategies and Translational Considerations","volume":"8","author":"Xu","year":"2019","journal-title":"Stem Cells Transl.
