Introduction: The objective of this randomised controlled trial (RCT) is to investigate the effect of a social networking site (SNS) on body dissatisfaction, facial and smile dissatisfaction, and face-related discrepancy, and whether these effects differ from the use of appearance-neutral Instagram images. We also aimed to investigate whether there are trends in increased self-reported use of social media and increased body dissatisfaction, facial and smile dissatisfaction, and face-related discrepancy. Methods: Undergraduate students were randomly allocated to an experimental group with idealised smile images or to a control group with neutral nature images. They completed pre-exposure questionnaires, then perused for 5 min their allocated images on individual Apple iPads via the Instagram application. Participants then completed the post-exposure surveys. The main outcome was facial dissatisfaction. Body dissatisfaction and total facial and body dissatisfaction were secondary outcomes. Simple randomisation was achieved with a computerised random number generator. Data were analysed using repeated measures ANOVA and multivariate regression analyses. Results: A total of 132 participants (mean age = 20.50 ± 2.21 years) were randomised to either the experimental group with idealised smile images (n=71) or the control group with neutral nature images (n=61). Baseline characteristics were similar between groups and no participants were lost. Exposure to ‘ideal’ facial images on social media decreases facial satisfaction (95% confidence interval [CI] = 0.85–1.05; P < 0.0001). Individuals with high baseline self-discrepancy scores are less satisfied with their facial features and body appearance (95% CI = 0.04–1.16; P = 0.036). Conclusion: This study shows that viewing SNSs with high visual media reduces satisfaction with facial appearance in the short term in men and women. This effect is greater in those with high self-discrepancy scores. Increased media usage was not correlated with increased dissatisfaction. Wearing braces or having had braces was shown not to influence post-exposure dissatisfaction.

Objectives To investigate the relationship between the use of social networking sites (SNSs) on patient perceptions, acceptance, and expectations of treatment using temporary anchorage devices (TADs) and to compare differences between patients from the United Kingdom and Brazil. Materials and Methods Cross-sectional questionnaires were administered to 39 participants at orthodontic practices in the United Kingdom and Brazil about patients' use of SNSs, exposure to TADs on SNSs, and thoughts on extractions, jaw surgery, or TADs as treatment options. Results UK patients prefer for clinicians to have SNS profiles (P = .022). Most UK and Brazilian patients want to see their clinician's work online (76.7%) and use SNSs to get information about treatment options (76.6%). There was a statistically significant difference in Brazilian patients' acceptance of TADs as a treatment option compared with UK patients, particularly if it meant avoiding extractions (P = .002), avoiding jaw surgery (P = .004), or reducing treatment time (P = .010). Knowledge of TADs was greater in Brazilian patients (P &lt; .001). Conclusions Patients use SNSs to obtain information about treatments and prefer clinicians to have social media accounts. Patients exposed to TADs on SNSs are more likely to accept them as an orthodontic treatment option. UK patients have less knowledge of TADs and are therefore less sure to consider TADs as an option. Brazilian patients are more confident in considering the use of TADs. Clinicians should consider increasing their social media presence to accommodate patients' expectations and acceptance of TADs.

The prevalence of an anterior open bite ranges in the literature from 1.5% to 11%, with great racial variance. Stable non-surgical treatment of an anterior open bite is notoriously unpredictable, with a high risk of relapse and an uncertainty of true skeletal change. Temporary anchorage devices (TADs) are increasingly used to enhance and simplify orthodontic biomechanics, enabling clinicians to push the boundaries of orthodontic treatment. In anterior open bite cases, TADs may be used predictably for molar intrusion and improvement of the overbite. We describe a 16-year-old male with a Class I incisal relationship on a skeletal I base and increased vertical proportions, complicated by a 4-mm anterior open bite secondary to a previous digit sucking habit. Treatment involved fixed orthodontic appliances on an extraction basis, and molar intrusion using TADs. TADs provide a safe and effective alternative to reducing an anterior bite in a patient whose growth is complete. CPD/Clinical Relevance: Understanding the options for the treatment of an anterior open bite and the limits of orthodontic camouflage will help clinicians provide their patients with the necessary information with which to make informed decisions.
