Dentofacial deformities can significantly impact an individual's quality of life, affecting facial aesthetics, self-esteem, and overall well-being. The combined orthognathic surgery-orthodontic treatment is the preferred approach for correcting moderate-to-severe deformities. However, patient satisfaction following orthognathic surgery remains a crucial outcome measure, influenced by various factors, including the type of malocclusion, surgical procedure, and demographic characteristics. This systematic review aimed to synthesize the available evidence regarding patient satisfaction following orthognathic surgery, exploring the effects of the type of malocclusion, surgical procedure, age, and gender on satisfaction rates, addressing a gap left by previous outdated reviews. A comprehensive literature search was conducted across multiple databases, including PubMed®, Scopus®, Web of Science™, and Embase®. Eligibility criteria were defined using the PICOS (population, intervention, comparison, outcomes, and study design) framework. Cochrane's ROBINS-I (Risk of Bias In Non-randomized Studies-of Interventions) tool was employed for non-randomized intervention studies within clinical controlled trials to assess the risk of bias. In parallel, a revised version of the Newcastle-Ottawa scale determined the methodological quality of cohort and cross-sectional studies. Sixteen studies were analyzed, revealing satisfaction levels ranging from 83% to 100%. Findings indicate that class III malocclusion patients report higher satisfaction than class II patients and satisfaction varies based on surgical type, with bimaxillary procedures generally yielding better outcomes. While most studies found no significant correlation between satisfaction and demographic factors such as age and gender, some suggested younger patients may express higher satisfaction and that female patients might report lower satisfaction levels. The review highlights the importance of effective patient communication and expectation management in achieving optimal satisfaction outcomes in orthognathic surgery. Limitations such as memory bias and methodological diversity across studies restrict the ability to perform meta-analyses, underscoring the need for further research in this area., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

This review aimed to evaluate the currently available evidence regarding the best method of correcting deep bites in growing patients. In September 2023, a search was conducted electronically across the following databases: PubMed®, Web of Science™, Scopus®, Embase®, Google™ Scholar, and Cochrane Library. In this systematic review, randomized control trials (RCTs), controlled clinical trials (CCTs), and cohort studies of growing patients with deep bite malocclusion who received treatment with the primary objective of treating the deep bite were included. Risk of bias of the included studies was assessed using two different tools; one tool was applied for RCTs and the other one for the CCTs and cohort studies. One RCT, one CCT, and one cohort study were included (85 patients). The flat fixed acrylic bite plane was superior in terms of duration of treatment when compared to the inclined fixed acrylic bite plane and the utility arch with posterior intermaxillary elastics. Limited evidence indicates that the inclined fixed acrylic bite plane causes a significant increase in the lower incisor inclination and a significant increase in the angle between the mandible and the anterior cranial base (SNB). However, limited evidence indicates that the utility arch with posterior intermaxillary elastics causes a significant decrease in the angle between the maxilla and the anterior cranial base (SNA). Regarding the vertical skeletal changes, it was found that the three methods were comparable; in each case, the vertical dimension of the face increased because of a significant increase in the lower first molar height. There is a need for further studies to strengthen the evidence of the treatment efficacy of the employed methods, with more RCTs to be conducted in this regard., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Rasol et al.)

Background: The study's objective was to assess the dimensional accuracy and reliability of dental digital models prepared by direct intraoral scanning and indirect scanning of the plaster models compared to the plaster models as the gold standard., Materials and Methods: This study included 20 patients. Nine had a class I malocclusion, seven had a class II malocclusion, and four had a class III malocclusion. Intraoral scanning was done for the upper and lower arches of all the patients enrolled in this study using an intraoral scanner (i700; Medit, Seoul, Korea). The next step was preparing the plaster model for the control group. Addition-silicone impressions were taken for each patient's arches. The impressions were poured according to American Board of Orthodontics (ABO) standards. Finally, the digital models of the indirect scanning group were prepared using a 3D desktop scanner (T710; Medit). In total, 26 measurements were made on the plaster and digital models. Paired t-tests were used to test for significant differences between the studied groups. The reliability of the studied techniques was tested using intraclass correlation coefficients (ICCs). Because of the multiple comparisons, the ɑ level was adjusted and set at 0.002., Results: No significant differences were found between the intraoral scanning group (20 patients) and the plaster models group (20 patients; P>0.002). The ICCs ranged from 0.814 to 0.993, indicating excellent agreement between the direct digital and traditional plaster models. There were no significant differences between the digital and original plaster models (P>0.002). ICCs ranged from 0.834 to 0.995, indicating excellent agreement between the indirect digital and original plaster models. No significant differences were detected between the direct and indirect digital models (P>0.002). ICCs ranged between 0.813 and 0.999, indicating excellent agreement between direct and indirect digital models., Conclusion: Both direct and indirect scanning techniques are accurate and reliable for digital model preparation and can be considered an alternative to traditional plaster models used in clinical orthodontics diagnostic applications. The intraoral scanning technique can be considered a valid alternative for indirect scanning of the plaster models to prepare digital working models during the digital design and fabrication of orthodontic appliances such as clear aligners., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Jaber et al.)

Background: There is insufficient information available in the literature about the efficacy of laser-activated irrigation (LAI) in removing dentine debris at different coronal-apical levels of the root canal system (RCS)., Objectives: To evaluate the efficacy of erbium (LAI) in removing dentine debris from different coronal-apical levels of the RCS when compared to passive ultrasonic irrigation (PUI) and conventional irrigation (CI)., Material and Methods: Forty-five single-rooted human teeth were split longitudinally into halves. In each sample, a standardized groove was cut 2-6 mm from the apex along the canal wall of the 1st half, and another standardized groove was cut 10-14 mm from the apex along the canal wall of the 2nd half. Each groove was filled with dentine debris mixed with sodium hypochlorite (NaOCl) 5.25%. The samples were assigned to 3 experimental groups according to the irrigant activation techniques (n = 15); (a) CI group, (b) PUI group and (c) LAI group. The amount of the remaining dentine debris was identified and scored using a stereomicroscope., Results: Laser-activated irrigation removed significantly more debris than PUI and CI systems. The efficacy of dentine debris removal was not affected by the root canal third within all groups., Conclusions: Erbium LAI enhances dentine debris removal from the artificial irregularities in the RCS.
