This study aimed to determine the efficacy of platelet-rich fibrin (PRF) injection on orthodontic pain perception during the 1st week of the alignment and leveling process. The study sample included 18 patients (11 females and 7 males). The patients were randomly divided into two groups, the PRF group (9 patients) and the control group (9 patients). The mean age of the sample members was 21.9 ± 2.5 and 20.8 ± 2.4 in the control and the PRF group, respectively. Conventional brackets were applied for both groups. PRF was injected into the six upper front teeth at a rate of 0.6 mm for each point before starting the primary wire insertion process. The pain parameters of each patient were evaluated for both groups during the 1st week of the alignment and leveling process by application of the Visual Analog Scale (VAS) at the durations of (2 h, 6 h, 1 day, 2 days, and 7 days) and all patients were followed up until the end of the alignment and leveling process. PRF injection can reduce pain perception in orthodontic patients, overall (P < 0.05), with an effect size of approx. 53 ± 0.13%. The biggest effect was observed 2 h after exposure (P < 0.1) which showed a 50% reduction in pain in the PRF group. No significant effects were observed at later times (P > 0.1). The present study concludes that PRF injection can be an effective alternative for decreasing pain perception levels; however, its efficacy needs to be leveraged immediately after the injection of PRF.

Active vertical control is critical in the treatment of hyperdivergent skeletal Class II malocclusion. The mechanics have been well shown as successful in the fixed appliance system with temporary anchorage devices (TADs); however, there are few relevant case reports in clear aligner therapy (CAT). The present case report describes the treatment of a severe hyperdivergent skeletal Class II case using CAT with the extraction of four premolars. Active vertical control was performed with TADs, which was facilitated by intrusion bulbs (IBs), that is, digitally designed and preformed vacuum bulbs on clear aligners for wearing intrusive elastics. The challenging camouflage case was finished with an improved profile and occlusion; specifically, the upper central incisors were intruded for 3 mm and the first molars for 1.8 mm, with counter-clockwise rotation of the mandible for 2.2° and a decrease of the ∠ANB for 2.6°. After a 4-year follow-up (the latter 2 years without retainers), the treatment results remain stable on the whole. According to the case report, camouflage treatment of hyperdivergent skeletal Class II case can be successfully achieved with active vertical control using TADs, facilitated by preformed IBs on the clear aligners.

Patients frequently use social media platforms to obtain information on dental treatment. This study aimed to evaluate the quality of the content prepared for patients seeking information on laser-assisted surgical treatment of the gummy smile on the YouTube platform. Videos were searched on YouTube using the keyword “fix gummy smile” in Google Trends. Considering the exclusion criteria, 30 out of 119 videos were selected for the study. Videos were analyzed in terms of general characteristics, video uploader, video content quality (VCQ), video information and quality index (VIQI), and Global Quality Scale (GQS). Statistical significance was established at P < 0.05. The average VCQ of the videos was 3.07 ± 1.39 out of a maximum of 30. Most videos (46.7%) were uploaded by dentists and 23.3% by healthcare institutions. Considering the video uploader, no significant difference was found in VCQ, VIQI, and GQS (P > 0.05). There was a positive correlation among the interaction index, the number of likes, and the reliability score (P < 0.05). Moreover, reliability score showed a positively directed association with GQS, total VIQI score, and total VCQ score (P < 0.01). Clinicians who upload content to YouTube should consider the importance and potential of YouTube to provide information to communities and create videos with more intellectual content to facilitate access to accurate information, especially related to health.

The eruption of the second molars may delay the therapy and lengthen the treatment time. To minimize excessive treatment prolongation, the principle of resistance factor elimination was applied to the unerupted second lower molar through a surgical incision on the occlusal gingival tissue. The 3.7 was successfully erupted and easily bonded the following month, to allow the archwires sequence.

The purpose of this study was to evaluate the relationship between psychosociocultural factors and dental malocclusion, facial appearance, and body perception. The study was carried out with the participation of 112 female and 113 male individuals between the ages of 18 and 25. Individuals were asked to answer the Rosenberg Self-Esteem Scale, Physical Appearance Comparison Scale Revised, and Sociocultural Attitudes Towards Appearance Questionnaire 4-Revised questionnaires. Individuals were divided into three groups Class I, Class II, and Class III according to dental molar relationships. Standard facial and profile photographs of individuals in all groups were taken and soft-tissue measurements were performed. There was no significant psychosociocultural difference between male and female individuals. However, individuals with Class III dental malocclusion compare their physical appearance more than other malocclusion groups and more experience body dissatisfaction (P > 0.05). Individuals with Class III dental malocclusion have higher lower face height, lower lip height, mentolabial angle, facial convexity angle, total facial convexity angle values, and lower forehead height/lower face height, nose height/lower face height ratio, and projection of the upper lip relative to the chin. Individuals with Class II dental malocclusion have lower chin height and anterior mandibular height/lower face height ratio, higher upper lip height/lower face height ratio, and upper lip height/anterior mandibular height ratio. Individuals with Class I dental malocclusion have a lower upper face height/lower face height ratio. Dental malocclusion groups have different facial soft tissue properties. Dental malocclusion and the facial appearance of individuals affect their lives in terms of psychosociocultural aspects.

This study aimed to three-dimensionally evaluate and compare anatomic condylar position to glenoid fossa in skeletal Classes I and II malocclusions along with vertical facial morphology (VFM). Full skull 50 cone-beam computed tomographies (CBCTs) were taken with teeth in maximum intercuspation of patients aged 18–45 years who were grouped as skeletal Classes I and II, 25 each based on ANB angle and the patient’s right condyle was analyzed on CareStream-3D viewing software. The VFM was categorized based on the Jarabak ratio. Statistical analysis was performed using Mann–Whitney and Chi-square test. In skeletal Class II when compared to Class I, the condyle in the glenoid fossa was anteriorly positioned with reduced anterior (P = 0.006) and increased posterior (P = 0.04) distance showing eccentric position. The condyle was also positioned lower suggesting an increased distance in the upper joint space (P = 0.04). The reduced height of the articular eminence indicated the condylar path and its position. The angle of articular eminence (P = 0.44) was decreased. Statistically, significant difference was not found between the various vertical facial morphologies. CBCT provides precise diagnostic values of joint spaces in skeletal Classes I and II to differentiate ideal condylar position from non-ideal according to different skeletal patterns, VFM, and also to notice minor discrepancies in joint spaces quantitatively. Depending on increased or decreased distances in the joint spaces, one can identify any temporomandibular joint-related discrepancies.

To find out success rate of mini-implants based on side of insertion and type of jaw. The aim of orthodontic treatment is to maintain sufficient anchorage control to create appropriate force systems that provide the desired treatment effects. Implants have been used as skeletal anchorage devices for orthodontic purposes. The following study is a systematic review of mini-screws as an intervention to evaluate the stability and different related clinical parameters to define the success rate (outcome) depending on the side of insertion (i.e., right side and left side) and type of jaw (i.e., maxilla and mandible following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses). A total of 52 articles were extracted for qualitative synthesis among which 24 articles were reviewed for meta-analysis and the results showed that the maxilla is a better placement site for insertion of mini-implant (MI) than mandible with the odds ratio of 0.58, that is, the MI placement in the maxillary region is 58% more successful than mandibular region. The other parameter showed that the insertion of MI on the right side was more successful with the odds ratio of 0.50, that is, the insertion of MI on the right side of the jaw is 50% more successful than on the left side of the jaw.

The study aimed to compare the efficacy of Titanium-Molybdenum (Ti-Mo) and Titanium-Niobium (Ti-Nb) alloy wires as retraction springs, by comparing: The amount and rate of canine retraction, the degree of canine rotation, the change in axial inclination of canines, and the associated anchorage loss. All 17 participants (age: 18–25 years) to be treated with the first premolar extraction approach by canine retraction were assigned Ti-Mo and Ti-Nb alloy T-loop springs to either of the upper quadrants randomly. Digital intraoral 3-D scans and panoramic radiographs orthopantomagram (OPG) were taken before (T0) and after (T1) the study period (4 months). 3-D superimposition was performed and using the digital models and OPG, changes in canine position, angulation, and anchorage loss were compared between the two groups. There was no significant difference between the two treatment groups for all the parameters pertaining to maxillary canine retraction, that is, canine retraction (P = 0.72), change in axial inclination of canines (P = 0.71), rotation of canines (P = 0.74), and anchorage loss (P = 0.13) as well as extraction space closure (P = 0.74). Ti-Nb and Ti-Mo alloy wires show a similar potency for use in retraction mechanics for orthodontic space closure.

This study conducted a comprehensive bibliometric analysis of articles published from 2012 to 2021 in three orthodontic journals: The American Journal of Orthodontics and Dentofacial Orthopedics (AJODO), The Angle Orthodontist (AO), and European Journal of Orthodontics (EJO). Eligible articles published from 2012 to 2021 in AJODO, AO, and EJO were retrieved from the Web of Science Core Collection database and subsequently processed using CiteSpace software to generate their characteristics, including authorship, institution, geographic origin, keywords, and citation profiles. The three orthodontic journals published 4001 articles from 370 institutions in 95 countries from 2012 to 2021. The AJODO published the most articles (45.5%) followed by AO (31.3%) and EJO (23.2%). The most prolific country was the United States (US), followed by Brazil, South Korea, China, and Turkey. The authors from the US were heavily engaged in international collaborations, especially with South Korea and Brazil. The country and institutions with the highest citation counts per publication were Italy and the University of Bern (Switzerland), respectively. Pandis N was the most prolific author, and Proffit W was the most-cited author in the 4001 publications. The keywords that emerged most frequently were “children” followed by “orthodontic treatment” and “malocclusion.” Four of the 10 most-cited articles were related to digital dental technology. This bibliometric analysis provides a complete picture of the research published in three major orthodontic journals over the past decade. It comprehensively analyzes the authorship, country of origin, institutions, keywords, and citation profiles of the articles.
本研究对2012年至2021年发表在《American Journal of Orthodontics and Dentofacial Orthopedics》(AJODO)、《The Angle Orthodontist》(AO)和《European Journal of Orthodontics》(EJO)三家正畸期刊上的文章进行了全面的文献计量分析。从Web of Science Core Collection数据库中检索2012 - 2021年在AJODO、AO和EJO上发表的符合条件的文章，随后使用CiteSpace软件进行处理，生成其特征，包括作者、机构、地理来源、关键词和引文资料。2012年至2021年，这三家正畸期刊发表了来自95个国家370家机构的4001篇文章。AJODO发表的文章最多(45.5%)，其次是AO(31.3%)和EJO(23.2%)。最多产的国家是美国，其次是巴西、韩国、中国和土耳其。来自美国的作者积极参与国际合作，特别是与韩国和巴西的合作。每份出版物引用数最高的国家和机构分别是意大利和伯尔尼大学(瑞士)。在4001个出版物中，Pandis N是最多产的作者，profit W是被引用最多的作者。出现频率最高的关键词是“儿童”，其次是“正畸治疗”和“错牙合”。被引用最多的10篇文章中有4篇与数字牙科技术有关。这个文献计量学分析提供了在过去十年中发表在三个主要正畸期刊上的研究的完整图景。它全面分析了文章的作者、原产国、机构、关键词和引用概况。

The demand for clear aligner treatment has increased in recent years. Thus, this study investigated public knowledge regarding Invisalign clear aligner treatment. A web-based survey was administered through different social media platforms covering different aspects of Invisalign treatment, namely: Treatment efficiency, patient discomfort, appliance esthetic attractiveness, oral hygiene maintenance, and treatment aesthetic results. Participants were also asked to outline their perception of Invisalign treatment cost. A Likert-type scale was used to rank the participant responses. Data were analyzed with the Chi-square test and Bonferroni correction for multiple comparisons. Out of 934 eligible adult participants, 19.6% were aware of Invisalign. Most of the Invisalign-familiar respondents were unaware of its cost (27.9%) but agree it is generally better (49.7%), requires fewer visits (38.2%), results in shorter treatment duration (39.4%) and reduced teeth discomfort (35%), more esthetically attractive (64%), yields easier oral hygiene maintenance (55.2%), and produces superior esthetic results (43.7%) than traditional braces. In addition, males and average-income participants were more likely to believe that Invisalign treatment produces superior esthetic results than traditional braces (P = 0.0002 and P = 0.002, respectively). Average-income participants also believed that Invisalign treatment was generally better (P < 0.0001). While participants in the age-range 55–64 years strongly believe, it is cheaper (P < 0.0001) than traditional braces. This study highlighted the lack of public knowledge about Invisalign treatment. The results also indicated the importance of ensuring public access to reliable information backed up by high-quality evidence.
