Parents of children who recently underwent an orthodontic consultation and were fluent in English were purposefully selected. Interviews continued until data saturation was achieved. Data were analyzed using inductive, manifest thematic analysis.Results: Fifteen parents, including 10 females and five males, participated. Four themes were inductively developed. Parents attributed several characteristics to effective PPC, including inclusivity, clarity, honesty, and comprehensiveness's. Specifically, they emphasized the importance of involving children and staff members in the consultation process, delivering honest and justifiable diagnoses and treatment plans, and adopting a holistic approach that considered all phases of the therapeutic process and various dimensions such as tasks, finances, and relationships between patients and care providers.Conclusions: The findings underscore the significance of care provider-related factors in PPC. These findings also emphasize the need for a collaborative and inclusive approach between orthodontic patients and care providers to foster effective PPC. Subsequent researchers should delve into the perspectives of pediatric patients, particularly adolescents, and care providers regarding effective PPC.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143733659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attachments were designed on the buccal, lingual, and buccolingual surfaces of the first molar. Different overcorrection torques were designed on the first molar. The displacement and stress of the whole arch were analyzed using a three-dimensional finite element analysis model.Results: Crown buccal tipping was observed during arch expansion, while the lingual attachment showed more buccal crown and lingual root movement. Based on the trend of displacement, 1.5° of buccal root torque overcorrection without attachments could lead to bodily movement, 1.8° with a lingual attachment, 0.5° with a buccal attachment, and 0.9° with a buccolingual attachment.Conclusions: Arch expansion is primarily achieved by teeth tipping despite attachments placed on the buccal or lingual side of teeth in CAT. Appropriate overcorrection of buccal root torque could contribute to the achievement of bodily movement.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143665618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study site was the Dental Radiology unit in the School of Dentistry of the Muhimbili University of Health and Allied Sciences (MUHAS), in Dar es Salaam, Tanzania. Cephalograms were imported to Quick Ceph Studio and then to Keynote for analysis. Minimum, maximum, mean, standard deviation, and mean difference were used to describe the data. Agreement between the two techniques was assessed by the Bland-Altman plot, linear regression, and interexaminer reliability tests. A level of significance was considered at P < .05, and a 95% CI was estimated for the outcomes in the study groups.Results: The majority of the mean values obtained from Quick Ceph were greater (P < .05) than those obtained from Keynote. According to Bland-Altman plots, all measurements were within the limit of agreement except for only five linear variables. The interexaminer reliability test showed no agreement between the two instruments for all linear parameters except for the LAFH: TAFH, whereas all angular measurements revealed good to excellent agreement (ICC: 0.75 to 0.97) between the methods.Conclusions: The measurements obtained with the Keynote software were found to be clinically reliable since the limits did not exceed the maximum acceptable difference between the methods. The two software instruments were considered to be in agreement and can be used interchangeably.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143652799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OGEs were measured in maxillary and mandibular anterior regions using posttreatment intraoral photographs (actual OGEs) and the final step from the first treatment plan in ClinCheck (predicted OGEs). Prediction performance indicators including precision, sensitivity, specificity, false positive rate, false negative rate, and accuracy were evaluated at each tooth site. Predictors of OGEs (age, crowding, crown morphology, tooth movement, tooth site, treatment duration, and attachment design) were analyzed using binary logistic regression.Results: Incidence of actual OGEs was like that of the ClinCheck predicted OGEs in the maxillary and mandibular anterior regions. The predictability of ClinCheck was satisfactory in both the maxilla and mandible, with accuracy rates of 94.0% and 86.0%, respectively. The most accurate prediction was for the maxillary central incisors, achieving a precision of 100% and an accuracy of 96.6%. The most significant predictors of OGEs included patient age at initial consultation, anterior crowding, tooth crown morphology, and type of tooth movement.Conclusions: Invisalign ClinCheck predicted OGEs in adult patients treated with four premolar extractions.

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":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
