This descriptive study examined quantitatively the task allocation between dentists and dental hygienists and the influence of patient age on NSPT provision using aggregated data from electronic patient records of patients aged 60+ attending public oral healthcare in Helsinki, Finland, in the period 2007\u20132016. Nearly 50% of the patients received NSPT, either time\u2010based or complex treatments. Of all appointments, 7% involved time\u2010based NSPT by dentists and 13% by dental hygienists. NSPT comprised 98% of all periodontal procedures, with dental hygienists performing 60%. Dentists mainly provided short (&lt;20\u00a0min) and \u226520\u00a0min treatments, each accounting for 8%\u201313% per age group, whereas longer and complex treatments were rare (1%\u20134%) and declined with age group. Dental hygienists increasingly performed \u226520\u00a0min treatments in the older age groups (12%\u201322%), with \u226530\u00a0min treatments being most common (32%\u201337%). Although \u226545\u00a0min procedures were infrequent, dental hygienists performed them twice as often as dentists, with a decreasing trend in the older patient groups. No obvious differences were found across study years. Findings emphasize dental hygienists\u2019 central role in periodontal care and suggest age\u2010related differences in treatment duration and provider allocation.<\/jats:p>","DOI":"10.1111\/eos.70068","type":"journal-article","created":{"date-parts":[[2026,1,5]],"date-time":"2026-01-05T06:43:41Z","timestamp":1767595421000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Task allocation in periodontal treatment among older adults in public oral health services in Helsinki, Finland, from 2007 to 2016"],"prefix":"10.1111","volume":"134","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-1749-2254","authenticated-orcid":false,"given":"Antti","family":"Kokkonen","sequence":"first","affiliation":[{"name":"Institute of Dentistry University of Eastern Finland  Kuopio Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3307-6605","authenticated-orcid":false,"given":"Kaija","family":"Hiltunen","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Diseases University of Helsinki  Helsinki Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6319-854X","authenticated-orcid":false,"given":"Miira M.","family":"Vehkalahti","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Diseases University of Helsinki  Helsinki Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2091-972X","authenticated-orcid":false,"given":"P\u00e4ivi","family":"M\u00e4ntyl\u00e4","sequence":"additional","affiliation":[{"name":"Institute of Dentistry University of Eastern Finland  Kuopio Finland"},{"name":"Oral and Maxillofacial Diseases Kuopio University Hospital  Kuopio Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,4]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/prd.12145"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2015.140520"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/jcpe.14128"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2016.160013"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0757.2005.00114.x"},{"key":"e_1_2_10_7_1","first-page":"3","article-title":"Risk factors for periodontitis","volume":"7","author":"Van Dyke TE","year":"2005","journal-title":"J Int Acad Periodontol"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/prd.12131"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/0022034514552491"},{"issue":"18","key":"e_1_2_10_10_1","first-page":"145","article-title":"Ageing, dental caries and periodontal diseases","volume":"44","author":"L\u00f3pez R","year":"2017","journal-title":"J Clin Periodontol"},{"key":"e_1_2_10_11_1","volume-title":"Oral health in the Finnish adult population: health 2000 survey","author":"Suominen\u2010Taipale AL","year":"2008"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1080\/00016357.2018.1451653"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12903\u2010017\u20100364\u20107"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.identj.2020.12.006"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12903\u2010020\u201001091\u2010w"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1177\/20501684211012587"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jebdp.2014.04.003"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0528.2008.00426.x"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/idh.12166"},{"key":"e_1_2_10_20_1","unstructured":"Periodontitis.Current care guidelines.
