Additionally, 20 non-treated people were included as a control group. The mobility of six mandibular anterior teeth was measured using a Periotest\u00ae device at each time points (before application of LR [T0], immediately after application of LR [T1] and 10 months after [T2] the application of the LR), and at only one time (T0) for the control group.\nResults: The mobility value was significantly lower at T1 and T2 compared to that at T0 (P &lt; 0.05); yet, there were no differences at T1 and T2 in all LR groups (P &gt; 0.05). No significant differences in mobility between the T0-T1, T0-T2, and T1-T2 time points were observed across the LR groups (P &gt; 0.05). The mobility of teeth 33 and 43 decreased over time across all study groups (P &lt; 0.05).\u00a0\nConclusions: Mobility decreased immediately after LR application, but did not change during the 10-month follow-up in the treatment groups. The observed decrease in mobility of canines over time, in contrast to other teeth, suggests a relationship between root size and mobility.\nTrial registration: The current clinical trial was recorded at clinicaltrials.gov, NCT06284499, 08\/02\/2024, retrospectively registered.<\/jats:p>","DOI":"10.2340\/aos.v84.44808","type":"journal-article","created":{"date-parts":[[2025,12,10]],"date-time":"2025-12-10T16:30:34Z","timestamp":1765384234000},"page":"577-582","source":"Crossref","is-referenced-by-count":0,"title":["Effect of different fixed lingual retainers on tooth mobility: prospective clinical study"],"prefix":"10.2340","volume":"84","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5640-0658","authenticated-orcid":false,"given":"Ey\u00fcp Burak","family":"K\u00fc\u00e7\u00fck","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3276-2408","authenticated-orcid":false,"given":"\u00d6zge","family":"\u00c7elik G\u00fcler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1510-8917","authenticated-orcid":false,"given":"Osman","family":"Fatih Arpa\u011f","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8119-5131","authenticated-orcid":false,"given":"Hatice K\u00fcbra","family":"Eren","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1183","published-online":{"date-parts":[[2025,12,10]]},"reference":[{"key":"135100","doi-asserted-by":"crossref","unstructured":"Littlewood SJ, Kandasamy S, Huang G.
