Aim: To assess whether orthodontic treatment affected the levels of OHRQoL in CLP patients and their families. (2) Methods: 226 individuals (111 with cleft and 115 control) and their parents were invited to complete the Oral Health Impact Profile-14 (OHIP-14) and Family Impact Scale (FIS), respectively. The Mann\u2013Whitney test was used for quantitative variables and the Fisher\u2019s exact test for categorical variables. The Spearman Rank Correlation Coefficient was used to correlate the results of the OHIP and FIS questionnaires. (3) Results: No significant difference was found between groups in OHIP-14 but FIS score revealed a significant difference between the two groups evaluated (p &lt; 0.001). Only the social limitation in OHIP score revealed a significant difference (p = 0.001). Regarding FIS score, the most affected dimensions were family activities (p &lt; 0.001), parental emotions (p = 0.001), and family conflict (p = 0.011). (4) Conclusion: Undergoing orthodontic treatment had a similar impact on the overall quality of life in CLP patients and non-cleft patients. Parents of cleft children had a poorer OHRQoL compared to what was perceived by their children and parents of non-cleft children.<\/jats:p>","DOI":"10.3390\/ijerph182312826","type":"journal-article","created":{"date-parts":[[2021,12,5]],"date-time":"2021-12-05T21:01:45Z","timestamp":1638738105000},"page":"12826","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["A Comparative Study of Oral Health-Related Quality of Life among Cleft Lip and Palate Patients and Their Families during Orthodontic Treatment"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3283-5104","authenticated-orcid":false,"given":"In\u00eas","family":"Francisco","sequence":"first","affiliation":[{"name":"Institute of Orthodontics, Faculty of Medicine, University of Coimbra, 3000-075 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0015-8604","authenticated-orcid":false,"given":"Francisco","family":"Caramelo","sequence":"additional","affiliation":[{"name":"Institute of Clinical and Biomedical Research of Coimbra (iCBR), Faculty of Medicine, University of Coimbra, 3000-075 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9391-9574","authenticated-orcid":false,"given":"Maria Helena","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Faculty of Dental Medicine, University of Porto, 4200-393 Porto, Portugal"},{"name":"LAQV\/REQUIMTE, University of Porto, 4160-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2615-2929","authenticated-orcid":false,"given":"Francisco","family":"Vale","sequence":"additional","affiliation":[{"name":"Institute of Orthodontics, Faculty of Medicine, University of Coimbra, 3000-075 Coimbra, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e1195","DOI":"10.4317\/jced.54043","article-title":"Tooth Abnormalities In Individuals With Unilateral Alveolar Clefts: A Comparison Between Sides Using Cone-Beam Computed Tomography","volume":"9","author":"Bezerra","year":"2017","journal-title":"J.
