Patients with anteroposterior maxillary deficiency and mandibular prognathism associated with a long-face pattern exhibit reduced anterior and lateral projection of the zygomaticomaxillary complex. Several techniques have been combined with orthognathic surgery to enhance the volume and definition of this region, such as zygomatic osteotomy. Two female patients, aged 22 (Case A) and 29 (Case B), with class II (Case A) and III (Case B) malocclusion, respectively, complained about facial aesthetics due to a long face and lack of malar projection. Le Fort I osteotomy to advance the maxilla, bilateral mandibular ramus osteotomy to set back the mandible, mentoplasty for advancement and width reduction, and zygomatic osteotomy were erformed. The patients underwent computed tomography scans, and superimposed images indicated that a volumetric increase in the malar region was achieved through the anterolateral movement of the zygomatic body. Improvements were noted in the paranasal region (Case A), better alignment of the upper and lower lips, the chin region, and an improved chin-neckline ratio (in both cases). The patients were satisfied with the results and are under follow-up. In summary, zygomatic osteotomy combined with orthognathic surgery proved to be a predictable and safe strategy for increasing malar prominence, with satisfactory aesthetic and functional outcomes.

Objective: Several studies have highlighted the toxic potential of bisphenol A (BPA), however, BPA release from orthopedic devices remains poorly investigated.Therefore, this study aimed to evaluate BPA levels in the saliva of children treated using Haas expanders. Methods: Twenty-two children of both sexes aged 6–10 years who required rapid maxillary expansion were recruited. One week after placement of elastics to separate the permanent molars, orthodontic bands were adapted, and maxillary impressions were obtained using alginate impression material. Haas expanders were fabricated using a standardized amount of acrylic resin. The bands were cemented using Transbond Plus Light Cure Band (3M).Saliva samples were collected at five time points: before (T0) and 30 minutes (T1), 24 hours (T2), 1 week (T3), and 1 month (T4) after Haas expander installation.BPA levels were measured using ultra-high-performance liquid chromatography coupled with Tandem Mass Spectrometry. The results were evaluated using oneway analysis of variance with Tukey’s post-hoc test (alpha = 5%). Results: BPA levels were below the recommended tolerable daily intake (TDI) at all timepoints;however, salivary BPA levels at T1 (70.324 ng/mL ± 37.05) and at T2 (18.015 ng/mL ± 11.22) were significantly higher compared to that at T0 (0.475 ng/mL ± 0.27) (P < 0.05). Conclusions Salivary BPA levels significantly increased 30 minutes and 24 hours after Haas expander installation and return to baseline values after 1 week. BPA levels did not exceed the TDI, suggesting that the use of Haas expanders may be considered safe concerning BPA exposure in children.

Objectives: Digital health (DH) is a revolution driven by digital technologies to improve health. Despite the importance of DH, curricular updates in healthcare university programs are scarce, and DH remains undervalued. Therefore, this report describes the first Junior Scientific Committee (JSC) focusing on DH at a nationwide congress, with the aim of affirming its importance for promoting DH in universities. Methods: The scientific committee of the Brazilian Congress of Health Informatics (CBIS) extended invitations to students engaged in health-related fields, who were tasked with organizing a warm-up event and a 4-hour session at CBIS. Additionally, they were encouraged to take an active role in a workshop alongside distinguished experts to map out the current state of DH in Brazil. Results: The warm-up event focused on the topic “Artificial intelligence in healthcare: is a new concept of health about to arise?” and featured remote discussions by three professionals from diverse disciplines. At CBIS, the JSC’s inaugural presentation concentrated on delineating the present state of DH education in Brazil, while the second presentation offered strategies to advance DH, incorporating viewpoints from within and beyond the academic sphere. During the workshop, participants deliberated on the most crucial competencies for future professionals in the DH domain. Conclusions Forming a JSC proved to be a valuable tool to foster DH, particularly due to the valuable interactions it facilitated between esteemed professionals and students. It also supports the cultivation of leadership skills in DH, a field that has not yet received the recognition it deserves.

Purpose: The aim of this study was to evaluate the influence of different cone-beam computed tomography (CBCT) acquisition protocols on reducing the effective radiation dose while maintaining image quality. Materials and Methods: The effective dose emitted by a CBCT device was calculated using thermoluminescent dosimeters placed in a Rando Alderson phantom. Image quality was assessed by 3 experienced evaluators. The relation-ship between image quality and confidence was evaluated using the Fisher exact test, and the agreement among raters was assessed using the kappa test. Multiple linear regression analysis was performed to investigate whether the technical parameters could predict the effective dose. P-values<0.05 were considered to indicate statistical significance. Results: The optimized protocol (3 mA, 99 kVp, and 450 projection images) demonstrated good image quality and a lower effective dose for radiation-sensitive organs. Image quality and confidence had consistent values for all structures (P<0.05). Multiple linear regression analysis resulted in a statistically significant model. The milliamperage (b = 0.504; t = 3.406; P = 0.027), kilovoltage peak (b = 0.589; t = 3.979; P = 0.016) and number of projection images (b = 0.557; t = 3.762; P = 0.020) were predictors of the effective dose. Conclusion Optimized CBCT acquisition protocols can significantly reduce the effective radiation dose while maintaining acceptable image quality by adjusting the milliamperage and projection images.
