The aim of this study was to evaluate the effectiveness of two different oral hygiene instruction methods on oral hygiene and the self-perception of oral health in older adults. Methods: This randomized controlled trial included participants aged 65 and older who completed a questionnaire on socio-economic factors, self-perceived oral health, and oral hygiene behaviours. Oral hygiene status was assessed using the Oral Hygiene Index\u2014Simplified (OHI-S). Participants were randomly allocated into two different groups, according to the method of oral hygiene instruction: a \u201cGeneral Approach\u201d (GA) (n = 28) and a \u201cPersonalized Technique\u201d (PT) (n = 26). After two months, a follow-up session was conducted. Data were analysed using descriptive and inferential methodologies. Results: The GA and PT methods were effective in promoting oral hygiene behaviours, with a significant increase in the use of interdental devices, but no significant differences were found between the two methods. Self-perceived oral health did not change significantly, neither after the instruction nor between methods. Significant improvements were achieved with both methods for the OHI-S, with significant differences between the two methods for the Calculus Index, where the PT achieved better results. Conclusions: Oral hygiene education leads to improvements in the adoption of oral hygiene behaviours and clinical indicators. Furthermore, a personalized approach promoted better results in clinical indicators.<\/jats:p>","DOI":"10.3390\/jcm13247642","type":"journal-article","created":{"date-parts":[[2024,12,17]],"date-time":"2024-12-17T03:46:02Z","timestamp":1734407162000},"page":"7642","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of the Effects of Oral Hygiene Instruction Methods on Oral Hygiene and Self-Perception in Older Adults: A Randomized Controlled Trial"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8095-0107","authenticated-orcid":false,"given":"In\u00eas Caetano","family":"Santos","sequence":"first","affiliation":[{"name":"Egas Moniz Center for Interdisciplinary Research (CiiEM), Egas Moniz School of Health & Science, 2829-511 Almada, Portugal"},{"name":"NOVA Medical School, Faculdade de Ci\u00eancias M\u00e9dicas, Universidade Nova de Lisboa, 1169-056 Lisbon, Portugal"},{"name":"Comprehensive Health Research Center (CHRC), Universidade Nova de Lisboa, 1169-056 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-1446-0036","authenticated-orcid":false,"given":"Catarina","family":"Cola\u00e7o","sequence":"additional","affiliation":[{"name":"Egas Moniz Center for Interdisciplinary Research (CiiEM), Egas Moniz School of Health & Science, 2829-511 Almada, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0921-342X","authenticated-orcid":false,"given":"Giancarlo De la Torre","family":"Canales","sequence":"additional","affiliation":[{"name":"Egas Moniz Center for Interdisciplinary Research (CiiEM), Egas Moniz School of Health & Science, 2829-511 Almada, Portugal"},{"name":"Division of Oral Diagnostics and Rehabilitation, Department of Dental Medicine, Karolinska Institutet, SE-14104 Huddinge, Sweden"},{"name":"Department of Dentistry, Ing\u00e1 University Center, Uning\u00e1, Paran\u00e1 87035-510, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8482-5936","authenticated-orcid":false,"given":"Lu\u00eds","family":"Proen\u00e7a","sequence":"additional","affiliation":[{"name":"Egas Moniz Center for Interdisciplinary Research (CiiEM), Egas Moniz School of Health & Science, 2829-511 Almada, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7651-3334","authenticated-orcid":false,"given":"M\u00e1rio","family":"Polido","sequence":"additional","affiliation":[{"name":"Egas Moniz Center for Interdisciplinary Research (CiiEM), Egas Moniz School of Health & Science, 2829-511 Almada, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0167-4077","authenticated-orcid":false,"given":"Jos\u00e9 Jo\u00e3o","family":"Mendes","sequence":"additional","affiliation":[{"name":"Egas Moniz Center for Interdisciplinary Research (CiiEM), Egas Moniz School of Health & Science, 2829-511 Almada, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1894-4870","authenticated-orcid":false,"given":"Helena","family":"Canh\u00e3o","sequence":"additional","affiliation":[{"name":"NOVA Medical School, Faculdade de Ci\u00eancias M\u00e9dicas, Universidade Nova de Lisboa, 1169-056 Lisbon, Portugal"},{"name":"Comprehensive Health Research Center (CHRC), Universidade Nova de Lisboa, 1169-056 Lisbon, Portugal"},{"name":"LA REAL, ULS S\u00e3o Jos\u00e9, 1900-028 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9881-3338","authenticated-orcid":false,"given":"Ana Cristina","family":"Manso","sequence":"additional","affiliation":[{"name":"Egas Moniz Center for Interdisciplinary Research (CiiEM), Egas Moniz School of Health & Science, 2829-511 Almada, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,15]]},"reference":[{"key":"ref_1","unstructured":"(2024, May 28).
