The aim of this in vitro study was to evaluate the shear bond strength (SBS) and adhesive remnant index (ARI) scores of two different adhesive applications of aesthetic brackets produced from permanent crown material using 3D-printing technology.

The objective of the present study was to compare the dentoskeletal effects of mini-screw-assisted rapid maxillary expansion (RME) in children with different body mass index (BMI) percentiles.

Background/Aim: Social media has become popular in recent years in dentistry. This study aims to evaluate the posts shared on Instagram related to accelerated orthodontic treatment.

This study aimed to evaluate the movement pattern of two different distalization systems during the distalization of the maxillary dentition from the maxillary canine to the second molar tooth and the stresses in the periodontal ligament by anchoring the mandibular dentition using the finite element analysis method. A standard three-dimensional finite element model was created that simulates the mechanics planned to be implemented with maxillary and mandibular teeth, periodontal ligaments, cortical and trabecular bones. Two different distalization mechanics were applied to this model with the Carriere Distalizer appliance (CDA) and the clear splint appliance (CSA), and two scenarios were created. The amount of displacement of the teeth from the maxillary canine to the second molar tooth was calculated, and the von Mises stress distribution in the periodontal ligament of the relevant teeth was visualized with a color scale. The current study found that the distalization movement of the CDA and the CSA after the force applied by anchoring from the mandibular dentition was similar. Although the amount of distalization obtained with the CDA is higher, it is seen that the mass movement is more significant in the CSA. The CDA and CSA showed a similar distalization pattern. The current study findings suggest that the CSA can be added to the Class II distalization treatment options such as the CDA. [ABSTRACT FROM AUTHOR]

BACKGROUND: Botulinum toxin, commonly referred to as botox, is frequently used in facial aesthetics, but also has therapeutic applications in various medical and surgical conditions such as bruxism treatment. OBJECTIVE: The aim of this research is to evaluate the information quality of only English resources available on the Internet regarding the use of botulinum toxin in the treatment of bruxism. METHODS: The terms "Botox + Tooth Grinding" selected for this study were searched on the Internet using the Google Search Engine, and the URLs of the top 150 websites containing only English pages were recorded and examined. The websites were assessed using DISCERN tools, the Journal of the American Medical Association (JAMA) benchmark, and HONcode tools. The website readability evaluation involved utilizing the Flesch Reading Ease Score (FRES) and the Flesch-Kincaid Grade Level (FKGL). RESULTS: A total of 130 websites met the inclusion criteria. The total mean DISCERN score (section 1 + section 2) for all websites was 39.75/75 (range: 15–67). The average FRES of all websites was 52.79, and the average FKGL score of all websites was 10.72. Internet blog websites had significantly higher DISCERN (Section 1) scores than other websites (p = 0.007). Only one website had the HON code. Internet blog websites showed better compliance with JAMA (authorship and currency) benchmarks. No statistically significant difference was determined related to FRES and FKGL scores between groups (p > 0.05). CONCLUSIONS: There is moderate and difficult-to-read information on the Internet about masseter botox injection for bruxism. Relevant guidelines are needed to improve the quality of websites about botulinum toxin for the treatment of bruxism. [ABSTRACT FROM AUTHOR]

Objective: Increased body mass index (BMI) is a growing problem worldwide and can affect medical conditions through morphological structures. The purpose of this study was to examine the hyoid bone position and pharyngeal airway dimensions on the sagittal section in different BMI percentile adolescent subjects.Methods: Fifty-five adolescent patients were subdivided into three groups, considering their BMI percentiles: Normal-weight (16 subjects), overweight (20 subjects), and obese (19 subjects). A total of 13 linear and angular parameters of head posture angle, pharyngeal airway dimensions, and hyoid bone positions were investigated on 55 lateral cephalometric radiographs.Results: Except for one hyoid bone measurement (RGN-H), there was no significant difference among groups. The RGN-H distances of obese and overweight adolescent subjects were higher than normal-weight adolescent subjects.Conclusion: Obese, overweight, and normal-weight adolescent subjects were likely to have similar hyoid bone position and pharyngeal airway dimensions.

Objective: This study aimed to evaluate the content and quality of YouTube™ videos about rapid maxillary expansion (RME). Methods: Videos on YouTube™ were searched using the term "palatal expansion." After sorting by relevance, the final 100 videos were analyzed for video demographics, primary purpose, information reliability, audiovisual quality, and Global Quality Scale (GQS). Also, viewers' interaction index and viewing rate formulas were calculated for each YouTube™ video. Mann--Whitney U test, Spearman's correlation coefficient and Intra-class Correlation Coefficient were used for statistical analyses. Results: YouTube™ videos about palatal expansion were mostly uploaded by patients and their relatives (51%). The reliability of the information in the videos with a GQS value >3 was significantly higher than those with a GQS value ≤3 (4.33 vs. 1.69) (P < .001). There was an excellent correlation between information reliability and GQS in videos uploaded by orthodontists and dentistry professionals (r=0.878, P < .01). Conclusion: YouTube™ is currently not an appropriate source of information about RME for patients. Orthodontists should refer patients to reliable sources of information on social media platforms.

Background: The aim of this study was to evaluate the content of oral habit videos on YouTube™.Materials and Methods: The four keywords "Oral Habits," "Thumb Sucking," "Tongue Thrust", and "Finger Sucking" relevant terms oral habits were searched on YouTube™. The videos sorted by view count were screened and evaluated. The following exclusion criteria were defined as; non-English videos, unrelated to a topic, poor audio-video quality, and duplication. A hundred videos were analyzed for general video characteristics (number of views, likes, dislikes, number of comments, and uploaded date) the purpose of the video, information content, audio-visual quality, and viewers' interaction index.Results: The top hundred videos have been viewed an average of 26,870.83 times. Most videos were uploaded by dentists (n = 29; 29.0%). Most of the videos (44.0%) were classified as having moderate general information content and 38.0% were rated as good, and 18.0% were rated as poor. Videos generally involved information about oral habits (82.0%), followed by personal experience (12.0%). The viewers' interaction index of all evaluated YouTube™ videos was 0.59. Good content videos had a significantly higher interaction index than the other groups (P = 0.011).Conclusions: YouTube™ videos about the oral habits are generally inadequate and patients must be recommended to view them with caution. High quality and more informative videos about oral habits in dentistry should be uploaded to YouTube™ by professionals. [ABSTRACT FROM AUTHOR]

Objective: The aim of the present study was to evaluate the content and quality of the popular videos on YouTubeTM about the treatment of cleft lip and palate. Design: Retrospective, YouTubeTM video analysis. Methods: The 3 keywords "cleft lip and palate surgery," "cleft lip and palate treatment," and "cleft lip and palate repair" were searched on YouTubeTM. After sorted by view-count, final 50 videos were analyzed for general characteristics, primary purpose, information content, relevance, audiovisual quality, and also viewers' interaction index, and viewing rate formulas were calculated for each video. Kruskal Wallis and one-way analysis of variance tests were used to compare the video parameters between good, moderate, and poor information content videos. Results: The viewing rate was significantly higher in good content videos (P =.003). Most of the videos were uploaded by a clinic (32%), a surgeon (20%), or individuals (22%) who shared their own experience. Most of the videos (54.00%) were classified as moderate general information content and 26.00% were rated as poor, and 20.00% were rated as good. Videos generally involved patient information (60.00%), followed by patient parent's experience (14.00%), and cleft lip and palate surgery (12.00%). The average viewers' interaction index of all evaluated YouTubeTM videos was 0.36. Conclusions: Although most of the videos were rated as moderate regarding the sufficiency of the information, the results of this study showed that YouTubeTM could still not be considered as a fully reliable source of information for patients on treatment of cleft lip and palate.
