Changes in OHRQoL were measured using the PIDAQ, while malocclusion severity was assessed using the PAR index and Index of Orthodontic Treatment Need. Data were collected before treatment (T0) and 1 month after treatment completion (T1). Responsiveness of the PIDAQ was evaluated using standardized effect size, standardized response mean, and Global Transition Judgment.Results: A positive, moderate overall correlation (r = 0.417, P < .05) was observed between changes in PAR and PIDAQ scores posttreatment, with significant improvements in OHRQoL reported by 88.1% of participants at T1. Subgroup analysis revealed strong correlations in cases of crowding (r = 0.711) and increased overjet (r = 0.703), while Class III malocclusion showed a weaker correlation (r = 0.263). Multivariate regression analysis revealed that change in PAR score was independently associated (R2 = 0.652) with change in OHRQoL score. The PIDAQ demonstrated responsiveness to treatment-associated changes, with a significant reduction in OHRQoL scores posttreatment.Conclusions: While a positive correlation between the objective measure of malocclusion severity (PAR) and subjective OHRQoL was identified, the relationship was moderate. The PIDAQ was found to be a responsive scale for assessing OHRQoL in orthodontic patients.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":"438-444"},"PeriodicalIF":3.2,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12418972/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Orthodontists (ORs), general dentists (GDs), and laypersons (LPs) then evaluated the attractiveness of the modified smiles.Results: A total of 79 LPs, 65 ORs, and 89 GDs participated in the evaluation.

Cone-beam computed tomography (CBCT) images were obtained before and after RME. Three CBCT coronal sections passing through the maxillary first molars, 5 mm anterior and 5 mm posterior, were used for quantitative assessment. NSD was calculated using the ratio of nasal cavity height to nasal septum contour. Additionally, five ENT professionals evaluated NSD qualitatively using scores from 1 to 3 through CBCT sequential axial and coronal sections. Absent NSD was scored as zero. Interstage changes were assessed using Wilcoxon tests. Spearman correlation and linear regression were performed to evaluate the association between quantitative and qualitative analyses (P < .05).Results: No significant change was observed in the NSD ratio. In pre-expansion CBCT images, absence of NSD and scores 1, 2, and 3 for NSD were found for 45.8%, 41.7%, 12.5%, and 0%, respectively. In the qualitative assessment, no significant change in NSD was observed after expansion.

A purposive sampling strategy aimed to recruit a representative cohort of orthodontic patients who had their orthodontic treatment in adolescence and had their treatment concluded at least 5 years previously. Twenty-one patients (13 females and 8 males) were interviewed using a prepiloted topic guide. These interviews were transcribed and analyzed verbatim, using the general inductive method of data analysis.Results: The thematic analysis revealed four key themes and related subthemes: (1) self-confidence and interpersonal communication, (2) social and professional opportunities, (3) oral health and function, and (4) challenges. In-depth analysis revealed positive treatment outcomes regarding enhanced self-confidence, social interactions, and perceived improvement in oral health and function. It also highlighted ongoing challenges with retainers and dissatisfaction with relapse.Conclusions: Orthodontic treatment can significantly impact patient lives. Orthodontic patients described direct long-term positive effects on their social lives and well-being. However, it is equally important to remain mindful of the long-term challenges that may arise after treatment, especially with retainer choices and relapse, enabling proactive measures to mitigate their impact.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":"205-211"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11842113/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142866904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
