Objectives: To evaluate the content, reliability, and quality of videos of patient experiences after orthognathic surgery on YouTube., Materials and Methods: Fifty videos that met the inclusion criteria were analyzed. The demographic characteristics of the videos were determined, and 13 points were used to classify poor and rich-content videos. The quality of the videos was evaluated using the Video Information and Quality Index (VIQI), Global Quality Score (GQS), and DISCERN. The Mann-Whitney U-test, Spearman correlation, and linear regression analysis were used for statistical analysis., Results: When poor- and rich-content videos were evaluated, there were statistically significant differences in video duration, number of likes, number of comments, and interaction index (P < .05). Compared to the poor-content video group, the GQS score, DISCERN, total content, and VIQI score of the rich-content video group were significantly higher. The interaction index and video duration and video information content quality showed a positive relationship., Conclusions: Although the quality of the videos shared by patients on YouTube was generally moderate, the content of the information was generally poor. Nevertheless, it should be considered that YouTube videos can be a source of information for patients who want to have surgery, which can affect the process., (© 2023 by the EH Angle Education and Research Foundation, Inc.)

Introduction: This study aimed to investigate whether the postoperative change in patients after orthognathic surgery, whose facial aesthetics was affected, led to detectable differences using Microsoft Azure, Amazon Web Services Rekognition, and Face ++ , which were commercially available face recognition systems., Methods: Photographs of 35 patients after orthognathic surgery were analyzed using 3 well-known cloud computing-based facial recognition application programming interfaces to compute similarity scores between preoperative and postoperative photographs. The preoperative, relaxed, smiling, profile, and semiprofile photographs of the patients were compared separately to validate the relevant application programming interfaces. Patient characteristics and type of surgery were recorded for statistical analysis. Kruskal-Wallis rank sum tests were performed to analyze the relationship between patient characteristics and similarity scores. Multiple-comparison Wilcoxon rank sum tests were performed on the statistically significant characteristics., Results: The similarity scores in the Face ++ program were lower than those in the Microsoft Azure and Amazon Web Services Rekognition. In addition, the similarity scores were higher in smiling photographs. A statistically significant difference was found in similarity scores between relaxed and smiling photographs according to different programs (P <0.05). For all 3 facial recognition programs, comparable similarity scores were found in all photographs taken before and after surgery across sex, type of surgery, and type of surgical approach. The type of surgery and surgical approach, sex, and amount of surgical movement did not significantly affect similarity scores in any facial recognition programs (P >0.05)., Conclusions: The similarity scores between the photographs before and after orthognathic surgery were high, suggesting that the software algorithms might value measurements on the basis of upper-face landmarks more than lower-face measurements., (Copyright © 2022 American Association of Orthodontists.

Objective: The purpose of this study is to determine whether or not the ImageJ program can be used to automatically determine the growth period of the hand and wrist which have different growth-development periods according to the density values in the phalanges in radiographs., Setting and Sample Population: Our study included hands-wrist radiographs of 270 individuals aged 8-17 years., Material and Methods: The study's participants were classified into 7 groups according to their skeletal maturation stage (PP2=, MP3=, MP3cap, DP3u, PP3u, MP3u, and Ru) which included pre-peak, peak, and post-peak periods. The total density values (TDV) and pure density values (PDV) in the distal, medial, and proximal phalanges were calculated using each radiograph in the ImageJ program. Analysis of variance (ANOVA) was used to evaluate the density values and chronological age, and pairwise comparisons were made using the post-hoc LSD test., Results: The total density value was graphically zigzagged in the mesial, distal, and proximal phalanges. However, the pure density value increased continuously until the post-peak period and decreased after the DP3u period until the Ru period. While no significant difference in total density values was observed between the growth periods for all three phalanges, a significant difference in pure density values was observed., Conclusion: It has been demonstrated in the ImageJ program that the peak growth period can be distinguished using the pure density values obtained from all phalanges of the third finger and that this method can be used as an alternative to the growth period detection through artificial intelligence., (© 2022 John Wiley & Sons A/S.

The aim of this study is to investigate and compare the changes in psychosocial status, self-esteem, and quality of life in patients treated with conventional and SF approaches. 14 patients (mean age 23.04±3.36; 9 male and 5 female) who met the inclusion criteria were included in the SF group; 18 patients with class III malocclusion (mean age 29.27±3.78; 9 male and 9 female) were included in the COS group. In the research protocol, the first questionnaires were carried out 2 weeks before surgery (T0); second survey approximately 4 weeks after surgery (T1); and the third one was done to patients after the treatment was completed (debonding) (T2). In our study, Orthognathic Quality of Life Questionnaire (OQLQ), Pyschosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), Oral Health Impact Profile (OHIP-14), Beck Depression Inventory second edition (BDI-II) and Rosenberg Self-Esteem Scale (RSES), surveys were conducted. No statistically significant difference was observed in all of the PIDAQ parameters and most of the OQLQ parameters within the COS and SF groups (P>0.05). When the BDI-II results were examined, different trends in scores were observed between the two groups, and this difference was found to be statistically significant (P<0.05). In the SF approach, progressive improvement was detected in the patients in terms of psychosocial and quality of life in the early period of treatment. The greater improvement in psychological and social characteristics in the SF approach compared to conventional orthognathic surgery may also be associated with a shorter treatment time., (Copyright © 2021 Elsevier Masson SAS.

The most appropriate treatment option for maxillary expansion in adulthood due to increased cyanosis in sutures is surgically assisted maxillary expansion (SARME). Skeletal and dental changes are observed with SARME. Three-dimensional imaging techniques are gaining importance with the developing technology in evaluating the changes that occur as a result of the treatments applied. The aim of study was to evaluate the soft tissue changes occurring in the nasal projection after SARME in 3-dimensional analyzes during the expansion and post-retention processes. The study sample consisted of 19 patients with a transverse maxillary deficiency of more than 5 mm (11 female and 8 male). 3dMD Vultus software was used for measuring height and width of the philtrum, superior alar, nasal and subnasal width; nasal length, nasal projection, nasal bridge width, nasal tip protrusion and upper face height) before surgery (T0), after the expansion phase (T1), and 6 months postoperatively (T2). A significant difference was found only subnasal width between pre-treatment and post-retention values. Surgically assisted maxillary expansion operations alter the nasal projection and this study certified these results with 3dMD face system. 3dMD face technique is an effective imaging technique for evaluating the soft tissues changes after orthognathic surgeries.

Objective: This study aimed to evaluate the unerupted mandibular second premolar (MnP2) angulation in individuals with different tooth agenesis in Turkish population., Methods: We retrospectively reviewed panoramic radiographs of patients treated at Akdeniz University. According to the agenesis, the subjects were categorized into three groups: 22 patients with unilateral MnP2 agenesis (Group 1), 22 patients with bilateral mandibular incisor agenesis (MnI, Group 2), and 22 patients with no agenesis excluding third molars (Group 3). The angle between the first mandibular molar and unerupted MnP2 (ɣ angle) and the angle between the mandibular basis and unerupted MnP2 (Ɵ angle) were measured on both the right and left sides in Groups 2 and 3 using the method determined by Shalish et al., Results: Groups 1 and 2 were compared with the control group with respect to (ɣ) and (Ɵ). No significant difference was found between Groups 2 and 3 on both the right and left sides (p>0.05). The comparison between Groups 1 and 3 revealed significant differences in the ɣ and Ɵ angle only on the left side (p>0.05)., Conclusion: Posterior rotation of the mandibular condyle during the growth-development period may be one of the factors responsible for the difference in the Ɵ angle between the MnI agenesis and control groups. A difference in the total number of teeth on the dental arch may be a reason for the differences in the ɣ angle between the MnI agenesis and control groups., Competing Interests: Conflict of Interest: The authors have no conflict of interest to declare., (© Copyright 2019 by Turkish Orthodontic Society.)

The aim of this comprehensive review is to introduce clinicians to the increasingly popularity Alt-RAMEC procedure, a method commonly used in the treatment of class III malocclusion in the last 15 years. Another application of the literature to enhance the skeletal effects of Class III treatment on the maxillae is the Alternative Rapid Maxillary Expansion and Constriction (Alt-RAMEC) procedure introduced by Liou, which improves the effectiveness of the maxillae relative to the surrounding sutures and the enhancement of the maxillae. In the Alt-RAMEC protocol, maxillae will be enlarged to be 1 mm per day, first enlarged to 7 mm, and then the 1 mm screw is closed. In other weeks, in this order the screw of the expansion device is turned on for one week and then closed for one week, completing the Alt-RAMEC protocol at the end of the 9-week process. In this review, we will discuss the advantages and disadvantages of the studies, which include successful treatments by applying this protocol, differences with other methods, its effect on the airway, and its advantages and disadvantages., Competing Interests: Conflict of Interest: The author has no conflict of interest to declare.
