Shear bond strength (SBS) was measured with a universal testing machine. Rheological properties were evaluated through a dynamic shear rheometer (DSR) test. Cytocompatibility was assessed with a CCK-8 kit. Bracket bonding and debonding procedures were performed on a head simulator. Adhesive removal effectiveness during bonding and debonding procedures was assessed.Results: There was no significant difference in SBS among four groups (0%: 10.06 ± 4.81 MPa, 2%: 8.98 ± 3.70 MPa, 4%: 10.88 ± 5.12 MPa, 6%: 8.09 ± 3.43 MPa, p > 0.05). DSR displayed that the rheological curves of group-2% and group-4% were close to that of group-0%. CCK-8 assay indicated cell vitality did not differ among group-0%, group-2%, and group-4% (p > 0.05). Group-4% showed less excess adhesive area (0%: 1.81 ± 1.58 mm2, 4%: 0.95 ± 1.33 mm2, p = 0.0465), less remnant adhesive area (0%: 0.73 ± 0.79 mm2, 4%: 0.07 ± 0.21 mm2, p = 0.0002), more time taken in removing excess adhesive (0%: 40.76 ± 6.44 s, 4%: 47.19 ± 8.40 s, p = 0.0046), and similar time taken in removing remnant adhesive (0%: 40.04 ± 10.05 s, 4%: 43.54 ± 10.18 s, p = 0.2365).Conclusions: Fluorescent orthodontic adhesive containing 4 wt.% of A-ZnOQDs with reliable SBS, rheological properties, and cytocompatibility was successfully constructed, with proof that it can be recognised and removed efficiently.","PeriodicalId":19652,"journal":{"name":"Orthodontics & Craniofacial Research","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143811933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After the first set of aligners was used, an intraoral scan was taken (T1). These scans were used as a control sample (n = 37). At the same appointment, the final aligner was activated using detailing instruments for the expression of rotation, torque and inclination according to the needs of the case. Second scans were taken 10 days later (T2) and treated as a study sample (n = 37). The two scans were then imported to Nemocast software and digital setups were performed for ideal finishing. The primary outcome variable was the number of refinement aligners.Results: Of the 222 teeth in total, 52.2% received activations for rotation (78.4%); inclination (6.9%) and torque (14.7%). Reduction in the number of aligners (T1-T2) was 1.62 ± 1.53 in the study sample; 1.93 ± 1.64 in subgroup A; 2.40 ± 1.71 in subgroup B (p = 0.000; p = 0.002; p = 0.007, respectively). Intergroup comparisons revealed that the difference between groups was not significant.Conclusion: This study is a pioneer to investigate the effects of detailing instruments in clear aligner practice. This intervention created a clinically small but statistically significant decrease in the number of refinement aligners when used on the final aligner only. Applications in earlier stages can have more prominent effects on the expression of movements, which might be the subject for future investigations.","PeriodicalId":19652,"journal":{"name":"Orthodontics & Craniofacial Research","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143753859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the association between the ACTN3 rs1815739 polymorphism through a Stop Codon (changing 577RR to 577XX) resulting in variations in mandibular morphogenesis.Materials and methods: Two hundred and fifty subjects were categorised into three groups. The control group (Group 1) comprised 100 patients with skeletal Class I malocclusion. The experimental group (Group 2) had 150 subjects with skeletal Class II malocclusions and a retrognathic mandible, divided into two groups of 75 subjects each based on the ramal heights (short ramal height-Group 2a) and (long ramal height-Group 2b). Saliva samples of the subjects were analysed to identify the genotype of the rs1815739. Tissue samples were taken to quantify the mRNA expression in the different alleles studied.Results: Polymorphism of the ACTN3 gene with risk homozygous TT genotype was linked only to subjects with short ramal height. The highly variable polymorphic site exhibited a substitution of the ancestral allele cytosine (C) with thymine (T) inhibiting protein synthesis. The mRNA expression was also found to be reduced (p < 0.05) in the short ramal height group.Conclusion: ACTN3 577XX polymorphism is more common among individuals with skeletal Class II malocclusion and short ramal height in the Dravidian population. It results in decreased protein expression in the masseteric muscle, which contributes to variations in sagittal and vertical facial dimensions.","PeriodicalId":19652,"journal":{"name":"Orthodontics & Craniofacial Research","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143743445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advanced algorithms and machine-learning techniques may enable orthodontists to analyse complex cases and predict treatment outcomes accurately. This technology facilitates the creation of customised treatment plans that consider individual tooth morphology and periodontal health, optimising force application and minimising treatment time. Since their introduction, clear aligners have gained popularity, with over 17 million people treated by 2023. Compared with fixed appliances, clear aligners offer advantages, such as better aesthetics, comfort and oral hygiene. Treating patients with a compromised periodontium requires accurate diagnosis and treatment planning. This paper reviews how AI-driven treatment planning software predicting root movement and visualising bone structures may impact treatment decisions and, ultimately, treatment outcomes. The technology behind machine learning and AI in designing clear aligners is discussed. Research shows that when viewing the cases in 3D, clinicians are more comfortable when treating crowding cases with a non-extraction approach using interproximal reduction (IPR) only. However, it was interesting to note that clinicians with extensive experience treating clear aligner patients were more comfortable using IPR to address severe crowding cases when viewed in 2D, compared with those less experienced with clear aligners. However, when the cases were visualised in 3D, both groups showed equal comfort in using IPR, as the roots were within the bone. AI-driven treatment planning software, utilising machine learning in conjunction with 3D modelling, may enhance the predictability of orthodontic movements while reducing treatment time and increasing patient satisfaction.","PeriodicalId":19652,"journal":{"name":"Orthodontics & Craniofacial Research","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143692971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radiant energy penetration was measured using a power meter, and Vickers hardness was assessed for composites cured through the samples. Mechanical properties were evaluated using uniaxial testing and three-point bending.Results: Both the resin type and lag time significantly affected radiant energy penetration and composite hardness. The effect of lag time varied by resin. Young's modulus from uniaxial testing showed significant changes only for the Pro3dure resin, while three-point bending indicated significant flexibility changes only for the SprintRay IDB 2 resin.Conclusions: The resin type and the lag time before post-print processing influence important functional properties of 3D-printed indirect bonding jig materials, including radiant energy penetration and flexibility. These findings suggest that optimising lag time may enhance the performance of 3D-printed indirect bonding jig materials.","PeriodicalId":19652,"journal":{"name":"Orthodontics & Craniofacial Research","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143674423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
